Description

The atm number that dustiness is 100-2000g/m3, tar content is 100-3000g/m3 The dust pelletizing system and its dust removal method that cleaner, the cleaner of gas form

Technical field

The present invention relates to the cleaner of the high oil gas body of atm number high-temperature high dust and dust removal method field, especially pyrolysiss of coal Field, the cleaner in biomass pyrolytic field, system and dust removal method.

Background technique

Dedirt cleaner under room temperature is numerous, selects suitable deduster, deduster according to the case where dedusting gas It is divided into following five class by its action principle；(1) mechanical precipitator includes gravitational precipitator, inertial dust separator, centrifugal deduster Deng.(2) Washing dust remover includes water-bath type dust cleaner, foam type deduster, venturi tube duster, water film type duster Deng.(3) filtration dust catcher includes bag filter and gravel bed filter etc. (4) electrostatic precipitator.(5) magnetic dust collector.

More in industry is sack cleaner.Dedusting refers to the technology that dedusting is filtered using filter bag.Filter The material of bag includes natural fiber, chemical synthetic fiber, glass fibre, metallic fiber.In filter process, gas by outside filter bag to Inside, dust is in filter bag outer surface gas by, to outside, dust is in filter bag inner surface, nineteen fifty-seven, pulse bag-type dust-removing in filter bag Device comes out.Processing air quantity (Q) processing air quantity refer to cleaner within the unit time institute energy purification gas volume.Unit is Cubic meter (m3/h) or per hour mark cubic meter (Nm3/h) per hour.It is one of most important factor in sack cleaner design. When being designed according to air quantity or selecting sack cleaner, deduster cannot generally run in the case where being more than regulation air quantity, it is no Then, filter bag is easy to block, the lost of life, pressure loss substantial increase, and efficiency of dust collection will also reduce；But air quantity can not be selected It is excessive, otherwise increase equipment investment and occupied area.Reasonable selection processing air quantity is often according to process condition and experience Come what is determined.

For sack cleaner, two factors are depended on using temperature, first is the highest bearing temperature of filtrate, Second is that gas temperature must be more than dew-point temperature.Due to a large amount of selections of glass fiber filter material, maximum operation (service) temperature is up to 280 DEG C, cooling measure must be taken to the gas for being higher than this temperature, temperature raising measure must be taken to the gas lower than dew-point temperature. It for sack cleaner, is not obvious using temperature and efficiency of dust collection relationship, this point is different from electric precipitation, to electric precipitator For, the variation of temperature influences whether that specific resistance of dust etc. influences efficiency of dust collection.

High-temperature dusty gas is often generated in chemical industry, petroleum, metallurgy, building materials, biological field of pyrolysis, especially in low order During pyrolysis of coal generates coal tar oil gas, decomposition gas, low-order coal substance is rolled with lesser particulate form or in air-flow Lower pyrolysis is driven, coal dust content is very high in the admixture of gas generated in pyrolytic process, and easily analyses in mixed gas containing carbons Substance such as tar is burnt out, class bituminous material can exist only in the environment of high temperature with gaseous state, temperature it is slightly too low or Environment is easy for being attached on filter mechanism from precipitation in gaseous mixture, causes filter mechanism to lose filtering function, make once changing Production can not continue.For decades, the mixed oil and gas dust removal problem of domestic and international amount dusty, in the scientific research of dozens of major country Under the effort of mechanism, also fails effectively to be solved always, cause low-order coal pyrolytic technique that cannot form industrialized production, directly The whole Coal Industrial pattern of our times is influenced, the low-order coal of staggering amount cannot obtain clean and effective utilization.

Colloid and asphalt content are higher in coal tar, and resin and asphalt is the predecessor of coking.Resin and asphalt Cellular construction be all using polycyclic aromatic ring system as the structure of core, the difference of the two be only molecular structure and molecular size range not Together.When coal tar is pyrolyzed evolution from coal in a gaseous form, generation is following in filtering body reacts: asphalitine bulky grain thermal depolymerization For asphalitine little particle, asphalitine little particle pyrolytic reaction generates fused ring compound or polycondensation reaction is graphitized to form coke, Fused ring compound pyrolysis is oil distillate or polycondensation is coke.

CN104147862A is to solve the problems, such as above-mentioned technique, proposes a kind of high-temperature oil gas, vapor, contains The dust filtration system of the gaseous mixture of the easy precipitate of carbons, the closed disengagement chamber including connecting admission line and exhaust pipe, institute It states and filter mechanism is set in closed disengagement chamber, the outer surface of the filter mechanism is connect with admission line, inner surface and exhaust pipe Road connection, the dust filtration system is interior to be arranged filter regeneration mechanism.By including connection admission line and exhaust pipe Closed disengagement chamber in be arranged filter regeneration mechanism, can filtering body after a period of work, filtering body filter capacity because It is declined to a great extent when can not meet normal work for the tar coal ash attachment in surface and stomata, by filter regeneration machine Filtering body is restored to due level up by structure work, and repeated regeneration directly reduces the investment of filtering body, also significantly Improve the service life of filtering body.

United States Patent (USP) US 09/271,741 discloses " method and apparatus for filter synthetic gas ", and which employs one To stick cleaner, each cleaner have one for receives the hot non-filter synthetic gas that need to be filtered entrance side, with And the outlet side of a synthetic gas for filtration to be discharged.Two cleaners can be accommodated with a shell, or be each Cleaner provides an individual shell.Alternately supply combustion air to each stick cleaner, so as to burn it is heavy The non-filter synthetic gas for allowing the filtering of another cleaner hot while accumulating the oxidable particle on a cleaner.One Or multiple switching valves are connected to the combustion air feedway, for the alternately supply combustion between two stick cleaners Burn air.

CN2297238Y discloses a kind of temperature gas dust remover, which has pipe heater outside, can solve gas The solid gas separation at high temperature of middle solid particle, but inside its patent document, relatively clearly introduce and only illustrating It can solve the thermal release problem of solid particle in the environment of high temperature, high pressure in this way, oil-containing high for Wind Volume Gas without reference to.

However, above-mentioned patent still has following several defects:

(1) it is asked present in high-temperature oil gas dedusting although the technical solution of above-mentioned patent disclosure solves to a certain extent Topic still with the progress of filter process, still has part tar precipitate and dust to combine, is formed and even quickly form ash Cake is attached to filtering body surface, easily cleaner is made comparatively fast to be blocked, and leads to one or when one group of filtering body works normally Between shorten, especially during the industrialized production of atm number amount dusty, be unfavorable for entirely interaction regenerating unit it is steady It is qualitative, and then greatly increase operation expense.

(2) United States Patent (USP) US 09/271, " method and apparatus for filter synthetic gas " disclosed in 741, however, should Cleaner is limited only to the lesser gas cleaning at high temperature of tolerance, and atm number is such as even more big in thousands of m3/h, m3/h up to ten thousand For the filtration yield of numerical value, the technical solution of the patent disclosure is obviously also helpless, first is that filter area is too small, only needle A kind of possible thinking and idea are provided for laboratory stage.Second is that faint air intake is not easy to guarantee regenerating unit Interior a large amount of filtering bodies carry out the uniformity and consistency of regenerative response, cannot also obtain the harmony of reaction temperature.In the U.S. In the technical solution of patent disclosure, heating device is only to heat to filter mechanism, and remove dust and gas to the atm number of entrance The preheating of body and huge cleaner device be it is extremely limited, because of the filtration system of industrialized production, diameter up to number Even more than ten meters of rice, more than ten meters of height are arrived tens of rice, filtering tolerance can up to upper even ten tens of thousands of sides incomparably per hour, and Adapt to atm number filtering gas cleaner preheat it is not in place in the case where, internal temperature be it is non-uniform, when high temperature contains Oil pyrolysis coal gas or biomass pyrolytic gas, if encountering the cleaner of local cold conditions, tar will be precipitated in oil gas quickly Mist, tar fog form oily precipitate in conjunction with grit and quickly block cleaner；Encounter the part of hot-spot, tar gas Polycondensation coking is attached in surface and the micropore of filter mechanism, with the progress of filtering, is also attached to the filter of filtering body Surface Creation It is increasingly thicker in the surface and gap of cake, the final cleaner for blocking filter synthetic gas.In addition, Chinese patent CN104147862A absolutely not mentions the device that heating preheating is carried out to filter mechanism, when high temperature oil-containing is pyrolyzed coal gas or life Material pyrolysis gas also brings along the rapid precipitation of tar and blocking up for cleaner if encountering the cleaner of cold conditions certainly Plug, naturally it cannot be guaranteed that guaranteeing that device is normally run during interaction switching is regenerated.

In addition, the case where for biomass pyrolytic, from the point of view of the case where retrieving at present, either compression blocks still dissipate Shape object, after pyrolysis the case where gas high there is also oil-containing dirt, various dedusters and its variation all cannot fundamentally solve big Dedusting problem in the high oil gas body of tolerance high-temperature high dust.

Summary of the invention

To solve the above problems, the present invention provides and a kind of is used in pyrolysis of coal, dust-laden in biomass pyrolysis process, containing tar heat Vent one's spleen the cleaner for filtering dust, cleaner composition dust pelletizing system and its dust removal method.

A kind of cleaner of the high oil gas body of atm number high-temperature high dust, including filter cavity, filter mechanism regenerating unit and Preheating device；Filter mechanism is provided in the filter cavity, the filter mechanism is limited in the inner space of filter cavity The inlet chamber and outlet chamber of isolation, the inlet chamber are connect with air filtration air inlet pipe is crossed, and the outlet chamber connects with air filtration escape pipe is crossed It connects；The filter cavity is provided with Guo Hui mechanism；The preheating device integrally preheats the filter cavity.

The present inventor is the study found that dust removal by filtration for atm number dust-laden, the pyrolysis gas containing tar, because of coal substance, life Substance is stirred or is pyrolyzed under air-flow drive, causes dust content in the admixture of gas generated very high, and mixed gas In be easily precipitated that substance such as tar is burnt, class bituminous material can exist only in the environment of high temperature with gaseous state, temperature containing carbons Slightly too low or environment is easy for slowly being precipitated from gaseous mixture once changing.The reason of being not only due to temperature, even Filter cavity persistently be suitable for high temperature in the state of, the too high admixture of gas of dustiness during the filtration process because molecule liquefaction, Solidification and the relationship between contact environment, temperature change are being physically contacted frequent position with filtering body, can still gradually appeared Containing the phenomenon that easy precipitate of carbons such as tar are burnt, class bituminous material is precipitated from gaseous mixture, it is enriched in filtering body surface and micropore It is interior, it is combined rapidly with the dust crossed in air filtration and generates filter cake, and be attached in filter cake surface and gap, and continue to tie in filter cake Enrichment is closed, the process of filtering pyrolysis gas is hindered, this is also that the high-temperature oil gas dust removal field stranded time is not at most, all the year round for a long time Up to the present it is held always without an industrialized high-temperature high dust oil-containing gases filtration system at the place for the problem of capable of capturing It is continuous to operate normally.The research and experiment of many decades are passed through by domestic and international dozens of leading company and well-known research institution, can not all solve Certainly the problem of the dedusting of high-temperature high dust oil-containing gases filtration system.

The present inventor has found finally in very long research process, entire cleaner internal cavity and the intracorporal correlation of chamber Temperature consistency is very crucial and important between component, each region.The gaseous mixture of the easy precipitate containing tar gas enters closed point After in chamber, it is microcosmic on gas molecule from air inlet pipe enter cavity after moment cause pressure to become since space becomes larger suddenly It is small, and the channel abnormal of micropore is narrow so that pressure becomes larger when close to filter mechanism, the easy precipitate containing carbons is in hot environment In interference just very easy precipitation by pressure change, tar coke and class bituminous material are liquefied as, if gas molecule During flowing, and because local heating, non-uniform heat flux lead to occur the irregular temperature of large area in cleaner Distribution, the temperature region indirectly uneven heat radiation necessarily occurred of height and heat transmitting, uneven irregular fever transmitting can distort Flowing trend in gas molecule, attaching space containing the easy precipitate molecule particles of carbons and dust particles, greatly increases and contains The probability of the easy precipitate molecule particles of carbons and dust particles collision and conglomerate polymers, oily asphalitine aggregate become larger Become weight, cannot also maintain vaporized state, while irregular air motion also increases tar coke molecule and dust molecule, mistake The contact frequency of filter body increases the probability that asphalitine polymerization is precipitated, be very easy to occur such as tar containing the easy precipitate of carbons it is burnt, Class bituminous material is from quickly precipitation is attached on dust the phenomenon that blocking filter mechanism normal filtration in gaseous mixture.

In the prior art, by the way that preheating is arranged in back-blowing mechanism in the periphery of filtering body or internal setting calandria Mechanism, such as CN105056647A and CN2297238Y necessarily lead to the uneven and not of preheating since the region of preheating is limited The dust removal requirement of the dust-laden of atm number, pyrolysis gas containing tar can be well solved, uniform entirety is not yet recognized in this field The importance of heating not yet recognizes the presence of such problems.In the prior art, even if in order to increase heating effect, It also is usually that more calandrias are set as CN105056647A, nevertheless, due to dependence being radiant heat transfer shape Formula is mainly merely able to preheat the region near filtering body, and the entirety that still can not achieve inner space and components is uniform Heating, and increase built-in electric heating mechanism can bring risk and operational risk to filtering high temperature inflammable gas.In addition, this field Technical staff also generally considers, either in the case where cleaner enlargement or lab pilot plant, lab scale, in filtering high temperature After the process of oil gas starts, the temperature of cleaner will soon be increased near the temperature value of filtering gas, without being further added by A whole set of complicated pre-heating system exclusively carries out preheating to it, belongs to the behavior being not necessarily at all, so in the prior art Seldom see the record preheated to it.

Even if there is the considerations of preheating, person of ordinary skill in the field also thinks only to be heated to high temperature to filter mechanism The temperature of oil gas, it will be able to solve the problems, such as that the temperature difference about filter mechanism and filtering gas is brought, in background technique Described in the documents mentioned.During industrialized production, cleaner is very huge, hundreds of easily, thousands of cubes The components of volume, the inside are more, and the inlet chamber and outlet chamber to whole system filter environment and carry out high temperature preheating, can generate Biggish economic cost；Even more important property is that it is logical to carry out heating to entire filter cavity using high-temperature gas or other modes A large amount of high-temperature gases are often introduced, and the high-temperature combustion gas being introduced into is easy to be mixed into high temperature oil-containing gases to be filtered, changes The composition of pyrolysis gas, reduces its economy, the gas separating treatment in later period is with regard to more complicated.While general high temperature oil-containing gases are all Be it is inflammable and explosive, the row that the condition of high temperature is a kind of danger is preheating to entire cavity with heat forms such as high-temperature gas, electric heating For so preheating to high temperature oil-containing gases cleaner, the economy of gas to be filtered on the one hand can be reduced, on the other hand As increase electrothermal mechanism, the switching operation such as high-temperature gas, its warm, the safety of filter process and reliable are reduced Property.Therefore, the generally introduction of this field is: high temperature dust, pyrolysis gas containing tar dust removal by filtration during, it is not necessary to removing Dirt equipment is preheated because pyrolysis gas start filtering will rapid heating equipment；Even if preheating, also need not preheating filtering body it Outer space and component, because being almost not involved in filtering with the not similar region of filtering body and component；It less will recognize that using whole Body preheating, because not only will increase heating cost and equipment cost to the result that it is integrally preheated, but also also likely brings heat Solve the reduction of reduction and the whole system safety of gas economic benefit.

Preferably, the filter mechanism is that plate-type filtering body or plate-type filtering body combine.

It is particularly preferred that the regenerating unit, preheating device share set of device.

Further, the regenerating unit, preheating device are connect with the inlet chamber, and the outlet chamber passes through circulation line It is connect with the regenerating unit, preheating device.

A kind of dust pelletizing system of the high oil gas body of atm number high-temperature high dust, the dust pelletizing system is by two sets or more set dedustings are set It is standby in parallel.

Described two sets or more set cleaner integration are arranged in parallel.

A kind of dust removal method of the dust pelletizing system of the high oil gas body of atm number high-temperature high dust, includes the following steps:

(1) using the preheating device being connect with the inlet chamber of the cleaner and/or outlet chamber, to one of dedusting Equipment (the first cleaner) carries out whole preheating, is preheating to the temperature close with high-temperature high dust temperature value containing tar gas；

(2) high-temperature high dust is passed through the first cleaner after preheating containing tar gas, entered from inlet chamber, by filtering Mechanism entered air filtration escape pipe from outlet chamber into outlet chamber；During the filtration process, back-blowing device is by filter mechanism surface Floating ash blow off；

(3) after a period of operation, the filter capacity of the first cleaner can be reduced to and not be able to satisfy filtration gradually When needing, another cleaner (the second cleaner) is preheated, when being preheating to close with high-temperature high dust temperature containing tar gas, High-temperature high dust is passed through the second cleaner containing tar gas, the second cleaner is started to work；

(4) stop being passed through the first cleaner high-temperature high dust containing tar gas, be passed through high temperature safe gas later, replace Fall the high-temperature high dust in the first cleaner containing tar gas, after being replaced, closes the first cleaner and cross air filtration escape pipe Valve inputs inlet chamber from Poor oxygen gas to the first cleaner and/or outlet chamber by filter mechanism regenerating unit, carries out the The regeneration of one cleaner；

(6) alternately switched by two sets or two sets or more of cleaner by " filtering-regeneration ", keep entire dust pelletizing system real Existing continuous work.

A kind of cleaner of the high oil gas body of atm number high-temperature high dust of the present invention, including filter cavity, the filter cavity Space in filter cavity is divided into the inlet chamber and outlet chamber of isolation, the filtering by interior setting filter mechanism, the filter mechanism The air inlet face of mechanism connects inlet chamber, and outlet face connects outlet chamber, setting and inlet chamber and/or outlet chamber on the filter cavity The preheating device connecting with inlet chamber and/or outlet chamber is arranged on the filter cavity for the filter mechanism regenerating unit of connection.It can Easily by the inlet chamber connection high-temperature high dust of be arranged in parallel two sets or two sets or more of filter cavity containing tar gas Air filtration air inlet pipe is crossed, outlet chamber connects the mistake air filtration escape pipe of gas after dedusting, uses setting and air inlet on the filter cavity The filter cavity of cold conditions be preheating to high-temperature high dust containing tar gas entrance by chamber and/or the preheating device of outlet chamber connection Near temperature value when cleaner, other filter cavities are simultaneously closed off；Filter cavity after preheating is passed through high-temperature high dust and contains Tar gas, high-temperature high dust enter the inlet chamber containing tar gas, enter filter mechanism, quilt by the air inlet face of filter mechanism The dust of filtering is stopped by filter mechanism air inlet face, is attached in filter mechanism air inlet face, and filtered high temperature contains tar gas Enter outlet chamber from filter mechanism outlet face；With the progress that high-temperature high dust is filtered containing tar gas, in filter mechanism air inlet face Floating dust and ash cake can quickly be formed, Guo Hui mechanism is arranged in the cleaner, can be convenient by the ash of the deposition in inlet chamber Dirt is discharged from cleaner.Filter mechanism regenerating unit can be realized the removing to floating dust and ash cake on filter mechanism, with Guarantee that entire cleaner works normally.

In the prior art, in the cleaner and method document of a large amount of high temperature oil-containing gases, few pairs of cleaners The related record heated.In the file preheated to cleaner that only a few is recorded, have outside filter mechanism Setting heater strip heats filter mechanism, that is, filtering body, to filtering body or filter core is made to add also by back-blowing mechanism Heat, but during industrialized production, heating and back-blowing mechanism to filtering body itself preheat filtering body, even It is the combination of the two preheating, is merely able to preheat filter stick itself and a part of cavity, it is difficult to realize atm number high-temperature high dust Comprehensive heating of oil-containing filter mechanism.Heater strip heats filter mechanism, because filter mechanism will realize filtering function, institute Filtering body surface cannot be centainly close to heating wire, but heated with the filtering body that the mode of radiation surrounds it, this kind preheating Mode effect is very poor, and the temperature for no matter how long being all difficult to realize whole cavity is consistent, and safety is worse.And with back-flushing valve pair Filtering body is heated, because the major function of back-flushing valve is to realize the blowing function of filtering body, caliber is compared to work Very thin, tolerance very little for the cleaner that industry metaplasia produces, even if the interruption without electromagnetism back-flushing valve acts on, cross tolerance also according to It is so too small, it is far from satisfying the whole needs uniformly preheated.It is so-called uniform, it is all of entire cleaner inner cavity after preheating The temperature of region and all components is relatively uniform, preheating the result is that each part temperatures in each position in cleaner inner cavity it is consistent or It is almost the same.The range integrally preheated, be in cleaner with filtering gas may by or may contact area or position.

After the present invention is by carrying out i.e. whole preheating comprehensively to inlet chamber and outlet chamber, so that each region in cleaner, The temperature of each component is relatively uniform consistent, and the high high dirt gas molecule of oil of the high temperature entered in the consistent overall situation of temperature can face Less temperature change and states of matter variation, even if under the action of dust, be also less susceptible to occur local space states of matter variation and Cohesion is precipitated, and greatly improves cleaner in the single use time for guaranteeing filter capacity.The whole preheating of preheating mechanism is such as big The high-temperature gas of air quantity is passed directly into inlet chamber or/and outlet chamber and integrally heats to cleaner, can be realized following three spies Point: contact, the accurate control without dead angle, heating temperature and heating process, and also preheating speed is fast, energy conservation, and economic benefit is aobvious It writes；Other heating methods such as outside sandwich integrally heated leads to hot wind, cavity surrounding integrally wraps up the ways of realization such as heat generating components May be implemented no dead angle, comprehensive preheating, preheating the result is that each regional temperature is almost the same in cleaner, but it is preferred still It is so the preheated form that a large amount of high-temperature gases for having circulating air to participate in integrally heat cleaner.In addition, it is critical that because For by the way of integrally preheating, during the filtration process, cleaner cavity inner wall, filtering body, partition, blowback Venturi tube etc. are all The temperature of more interior fittings is relatively uniform, and the intracorporal heat transfer of chamber is less, the filter in neighboring area and central filter area The case where structure strainability is consistent, and generation precipitate is with ash cake is consistent, and the effect of blowback is consistent, even during regenerated Regenerated progress is consistent, substantially increases the controllability of system, reliability of operation and consistency.Simultaneously reduce two sets or Person covers the switching frequency and regeneration frequency between filter cavity more, has shortened the single reproduction time of cleaner, and then ensure that The filter effect of cleaner.It avoids occurring local filtration body during the filtration process losing filtering function, Partial filtration body still In good working state, caused by a large amount of filtering mechanism works out of step conditions.Nonsynchronous result not only influences filter quality And effect, the difference of the putty coke content on different zones filter mechanism surface can be also brought, what filter mechanism different zones generated The case where ash quantity is different, generates bridge formation are also different.So-called bridge formation is between filtering body because a large amount of dust connects together, This position loses the space of gas flowing, and biggish expansive force is generated between adjacent filtering body.Nonsynchronous result It can also bring, some places between filtering body are built bridge, some places are not built bridge, some local arch formations are serious, some Local arch formation is relatively light, then it is also inconsistent by the lateral expansion power in the filter mechanism portion generated of building bridge, lead to part There is breakage phenomenon in filtering body, not only significantly affects filtering body filter effect, also directly affects cleaner service life.Separately Outside, because filtering mechanism works process it is asynchronous, can also bring the serious problems during blowback, same backflowing gas amount and anti- The significant difference that frequency has pressure and flow velocity to the nonsynchronous filtering body of filtration condition is blown, it can be straight during moment blowing Connecing causes pressure difference between different filter mechanisms excessive, and then can bring risk.It yet further says, in filter regeneration In the process, because of the difference of different zones filter mechanism surface ash quantity, inevitably there is Partial filtration in the difference of coke content in ash cake Body regeneration terminates already, Partial filtration body regenerates not foot phenomenon, all seriously affects the using effect and service life of cleaner.

Molecular state of oil gas itself be it is unstable, in the high temperature environment, often because heat absorption and cause two or The interaction of more than two organic molecules is combined in the form of covalent bond forms a macromolecular, and with shaking off for small molecule and Condensation reaction constantly occurs, molecule is solid-state from gaseous, liquid coking, and ash cake is generated in conjunction with dust and hinders filtering.And it is of the invention Technical solution whole preheating is carried out to filter cavity, filter the relatively uniform uniform stabilization of environment temperature, heat occurs for asphalitine Solution and polycondensation reaction probability substantially reduce, and also do not occur low-temperature liquefaction phenomenon, and tar is burnt, the reduction of class bituminous material amount of precipitation is straight Connect the speed for inhibiting filter cake to generate.For each filter mechanism or filtering body, slightly problem can bring about the fast of filter cake Fast-growing at and cause filter mechanism to fail or scrap, directly affect the normal work of the large high-temperature chemical industry equipment worked continuously into Journey, as being most difficult to handle most important key technique in dust removal process, the reduction of filter cake production quantity and formation speed it is big It is big to reduce, the frequency and processing difficulty of filter mechanism regenerative response will be substantially reduced, filter mechanism is improved and restores filter capacity Rate, to overcome the long-standing technical problem in this field.

In the present invention, it is combined by setting plate-type filtering body or plate-type filtering body for the filter mechanism, it can be with The status of current technological development is preferably adapted to, plate-type filtering body is easy to process, it is easy to accomplish enlargement, during use It is easily installed, seals, replaces and debugs, especially the combination of plate-type filtering body, additionally it is possible to well solve single plate-type filtering The problem that body filter area is too small, filtration yield and filter capacity are too low.In addition, with the further development of new material new process, The structure of plate-type filtering will be relatively reliable durable, convenient for disassembly and assembly.

For the present invention, by way of filter mechanism being arranged to partition and multiple tubular filter bodies combine, Counterbore is set on the partition, tubular filter body is fixed on partition by counterbore, the inner surface of the tubular filter body with The outlet chamber connection, outer surface is connect with the inlet chamber.Partition combines with multiple tubular filter bodies and solves large plate The problem of quality of formula or the filtering body of board-like combination production cannot guarantee very well, tubular dedusting equipment is with the knot of its cylindrical body Structure improves the stabilization of construction bring durability and strainability of the surfaces externally and internally in conjunction with self-filtering micropore well, And cleaner cavity is divided into two spaces with a partition, multiple or a large amount of tubular filter body can be certain The filtration area that filtering body is greatly increased in space greatly improves it and filters air capacity, is suitable for large-scale industrialization Production.

Filter mechanism physics deashing mechanism is set in the cleaner, the filtering being arranged in the outlet chamber is such as set Mechanism back-blowing device such as periodically carries out physical contact and brushes away the brush resistant to high temperature that ash is floated on filter mechanism surface, or to mistake Filter structure carries out the deashing mechanism of air flow blowing, or setting in outlet chamber, after crossing air filtration air inlet pipe valve and closing, into Air cavity realizes the mechanism of instantaneous negative pressure, it is therefore an objective to realize the cleaning to filter mechanism surface floating dust.

For the present invention, multiple tubular filter bodies on the partition are divided into several groups, and every group of tubular filter body is corresponding A set of filter mechanism back-blowing device is set.Why multiple groups are divided into, one can be allowed during filter mechanism works normally The starting of filter mechanism back-blowing device is covered, other filter mechanism back-blowing devices are not turned on, avoid in all filter mechanism back-blowing devices When blowback simultaneously, bring the pressure in the obstruction and cleaner that high-temperature high dust is flowed containing tar gas in whole system acute Increase, influences whole system normal work, or even act on pyrolysis system and bring danger.It is controlled by a set of blowback control mechanism Several groups filtering body, a group by a group regular intervals of time blowback can guarantee that remaining is more during one group of blowback is in blowback Group filtering body is still filtering, so that so that the integral filter of cleaner is worked is not being influenced by big.

For the present invention, the filter mechanism back-blowing device includes the blowback Venturi tube being arranged in the outlet chamber, The blowback Venturi tube big opening end is connect with the partition towards the surface of outlet chamber, the outlet end of every group of tubular filter body Correspondence protrudes into the blowback Venturi tube big opening end, and a blowback jet pipe, the blowback is arranged in the blowback Venturi tube osculum end Jet pipe stretches out the filter cavity shell and is connect by electromagnetism back-flushing valve with high temperature and high pressure gas generating device.Filter mechanism makes After a period of time, surface will generate a certain amount of floating dust, and electromagnetism back-flushing valve periodically turns on, and high temperature and high pressure gas will be by anti- Pipe ejection is blowed and sprayed, negative pressure is formed at the osculum end of Venturi tube, drives cleaner outlet plenum around the osculum end of Venturi tube Filtered coal gas enters Venturi tube together, generates pressurization in Venturi tube big end and penetrates filtering body, is especially to filtering body ontology The floating dust of filtering body air inlet face is blown off, continues to be able to carry out work.

The filter cavity setting safe gas replaces mechanism 15, before it is regenerated, with safe gas replacing machine Structure changes the remaining high-temperature high dust in inlet chamber 3 and outlet chamber 4 containing tar gas, when Poor oxygen gas being avoided to enter and high Wen Gaochen vigorous reaction containing tar gas, or even there is safety accident.Guo Hui mechanism 16 is arranged in the cleaner bottom, described Guo Hui mechanism 16 includes letting out ash pipe and ash-leaking valve.Mistake air filtration of the high-temperature high dust containing tar gas from high-temperature high dust containing tar gas into Tracheae 11 enters inlet chamber 3, enters outlet chamber 4 by the filtering of plate-type filtering body 2, entered back into air filtration escape pipe 12, enters Lower one of program.The filter mechanism regenerating unit 5 connecting with inlet chamber 3 is set on the filter cavity 1, and the filter mechanism is again The input of Poor oxygen gas when 5 completion system of generating apparatus needs to regenerate, including Poor oxygen gas input pipe 6, the Poor oxygen gas input Pipe 6 is connect with inlet chamber 3, in addition, exhaust pipe 7 is arranged on air filtration escape pipe 12 in described cross.When the cleaner filtered When filtering body 2 is blocked, input suitable Poor oxygen gas with Poor oxygen gas input pipe 6, allow be blocked 2 surface of filtering body deposition Oxidable particle be oxidized, restore the gas permeability of filtering body, suitable oxygen deprivation has carrier of oxygen control filtering body surface heavy Temperature when oxidation rate and the cleaner regeneration of long-pending oxidable particle.Filter mechanism blowback is set in the outlet chamber 4 Preheating device 9 is arranged on described cleaner 30A, 30B for device 8, and the preheating device 9 is by fuel channel and valve, air blast Machine, air hose and valve, burner, combustion chamber, combustion gas outlet conduit composition, the combustion gas outlet conduit and cleaner air inlet Chamber 3 connects, and heat is continuously fed to cleaner by combustion gas outlet conduit by the heat that combustion chamber generates, and makes cleaner Temperature reaches 450 DEG C of temperature of pyrolysis of coal oil gas or so.

Comparative example one:

The difference of this comparative example and embodiment five is only that the difference of preheating mechanism.In the comparative example, without whole pre- The Wind Volume gas of heat, but electrothermal mechanism is set on each filter cavity surface.It finds during the work time, to tubulose mistake The ambient temperature of filter body increases, and after being heated to the temperature close with high-temperature high dust temperature containing tar gas, stops preheating, in high temperature It is filtered by high-temperature high dust containing tar gas on cleaner 30A, every 5 to 10 minutes, blowback one is taken turns, can be small with continuous production 15 When, just more than 10000 Pa, blowback cannot realize the normalization of its filter capacity, need to stop for inlet chamber and outlet chamber pressure difference Work is evacuated blower excess constant current into regeneration stage, and production is forced to stop, after discovery, which removes, to be checked to cleaner opening There is coal dust frame in many places between dirt equipment filtering body, and 20mm or so hard shell occurs in filtering body appearance, rub hard shell sense with finger Higher containing oil by hard shell, closer to filtering external surface, oil content is higher；For only filling the filtering of 480 filtering bodies Body, send 5 people to filtering body dismantle, with 68 hours, and filtering body damage 112, remaining filtering body further through hairbrush, alkali cleaning, Ultrasonic cleaning wastes many artificial, materials, and filtering body damages 83 again, spends quite surprising.

" parallel connection ", be herein two or more cleaners inlet chamber with cross air filtration air inlet pipe connect, outlet chamber and Cross the connection of air filtration escape pipe.Two or more cleaners will not interfere with each other, and can both use, and also can be used alone simultaneously One, such as the concept in parallel in lighting circuit.

Parallel connection as described herein can be two or more cleaners and access air filtration air inlet pipe side by side and crossed air filtration It between tracheae, can also access between pyrolysis plant and equipment for after-treatment side by side, to realize the dust removal and filtration of air filtration.

Two or more cleaners of " parallel connection " described herein, can be identical, and such as two dedustings in parallel are set It is standby, it is all cleaner described in embodiment seven.Can also be not exactly the same, a such as dedusting recorded for embodiment one is set Standby, another connected in parallel is the cleaner that embodiment three is recorded.Possibly even one is removed for plate-type filtering body structure Dirt equipment, another is the cleaner of partition and tubular filter body structure.

As is generally understood, particularly relating to for " high temperature and high pressure gas " of blowback can be by tubulose The effective blowback of substance of the reduction filter effect adhered on filter mechanism is fallen, and not will lead to filter mechanism temperature simultaneously and obviously drop Low gas.
