Background technology
Current energy source shortage and problem of environmental pollution highlight day by day, and the energy-saving and emission-reduction and the environmental protection that realize industry become very urgent.The develop rapidly of the related industries such as electronics, semiconductor, medicine, make the VOCs (VOC) produced in process of production keep ground contamination, destroy ecological environment.
VOCs (VOC) is hereinafter referred to as VOCs
VOCs common composition and physical property are as following table:

| HMDS (hmds gastral cavity) | 161.4 | 126 | C 6H 19Si |
The characteristic of VOCs:
According to the boiling nature of emission gases, can classify as high boiling VOCs (boiling point is greater than 150 DEG C), general boiling organic compounds (boiling point more than 30 DEG C, less than 150 DEG C) and room temperature are the organic compound that gas exists.
And smelly, malicious and general VOCs can be divided into according to the chemical property of emission gases.It also causes harm in various degree to environment.
The general processing method of VOCs:
Hybrid treatment system: runner inspissator+regeneration regenerative oxidation stove (RegenerativeTO; RTO)
Concentration runner system: this system divides adsorption and desorption, cooling three regions, system is adsorbed the VOCs in waste gas and is carried out elevated temperature desorption to the VOCs after absorption, and the runner after desorption enters cooling zone, in order to follow-up absorption after cooling, periodic duty, Zhou Er renews.
Incinerator system: carry out high temperature 732 DEG C of cracking to through runner desorption VOCs out, the composition after cracking respectively with O
2reaction, generates carbon dioxide and water vapour.
Heat-exchange system: the gas after incinerator gas out and desorption carries out heat exchange, makes the gas temperature entering oxidation furnace reach suitable temperature, thus reduces oxidation furnace combustion fuel.
Each state all endeavouring to research and develop VOCs treatment technology of new generation, especially payes attention to VOCs incineration technology especially.This incineration treatment technology carries out heated oxide, cracking VOCs exactly, is carbon dioxide (CO by hydrocarbon conversion
2) and water (H
2o) typical process.This process raises processing procedure EGT to interrupt C-H bond, and produce carbon dioxide (CO
2) and water (H
2o).The generation of this process also produces exothermic reaction.The thermal source demand of incinerator mainly adds the heat required for hot-air to organic solvent cracking, and organic solvent, also can release portion heat energy while cracking, and reduce the demand to fuel.Burn burner hearth should remain on 800 DEG C ~ 850 DEG C and allow VOC
sin burner hearth, be detained a period of time oxidized, cracking, should not be less than for 2 seconds during this period of time.VOC
safter carrying out heated oxide, cracking, produce carbon dioxide (CO
2) and water (H
2o) be discharged into air, environment is not polluted, but still with heat, this just needs a good combustion system and heat recovery equipment, makes emission gases reach state-set standard, reduces the consumption to the energy, eliminate pollution to ecological environment.
At present, two-tower type, the positive extensive use of three-tower type VOCs incinerator.The complex structure of two-tower type, three-tower type incinerator, bulky, VOCs heated oxide, cleavage rate 95 ~ 99%.These incinerators are designed with regenerator, and cellular ceramic structure heat storage tank is filled in regenerator inside, and heat recovery efficiency can reach 93% (± 2%) left and right.Heat storage tank segmentation is carried out absorbing heat, heat release, blowing, in blowing section, air inlet duct and air discharge duct heat switch, and reach the object of recuperation of heat.But the machine that the opens stage of two-tower type, three-tower type VOCs incinerator needs preheating, before the non-heated oxide process of VOCs, the burned machine of ceramic heat-storing groove is heated gradually to operating temperature, needs to consume a large amount of fuel.VOCs carries out heat absorption by the heat storage tank of heat release and heats up, to burning after hearth combustion, the gas of high temperature again through heat storage tank heat release, heat storage material.Utilize the heat absorption of ceramic heat-storing material, exothermic process carries out waste heat recovery, although decrease part of fuel consumption, waste heat recovery efficiency is low; Use a large amount of porcelain heat-storing materials, make body of heater bulky, add incinerator construction cost; Because the cellular loose structure of heat storage tank, pipeline is elongated, VOCs turbulent flow type air-flow turns round more in burner hearth, windage is large, air-flow velocity is low, is easily detained remaining unburned VOCs material, causes pipe blocking, need removable parts heat storage tank and increase blowing blower fan at any time, too increase construction cost and maintenance cost.These have become current two-tower type, the cost of three-tower type VOCs incinerator remains high, the principal element of complex management, Frequent Troubles, maintenance difficult.
In order to improve VOCs heated oxide, lysis efficiency, reduce the consumption of fuel, reduce burning construction cost, we are according to the general principle of " spiral of Archimedes ", design seriation L-type non-phase transformation super heat-conductive pipe heat reclamation type VOC
sincinerator, the combustion chamber of incinerator is designed to ceramic spiral of Archimedes burner hearth, and the entrance angle of air outlet and burner hearth is 13.5 degree.Be concentrated, after VOCs after desorption enters ceramic spiral of Archimedes burner hearth, form spiral air flow, fully mix with combustor flame, burn completely.Spiral air flow time of staying in burner hearth burns furnace superintendent than two-tower type, three-tower type VOCs, can not produce residual gas and residue, both decrease the consumption of fuel, also make efficiency of combustion significantly improve.Seriation L-type non-phase transformation super heat-conductive pipe heat reclamation type VOC
safter incinerator adopts new combustion system and combustion process, make VOCs at the first combustor burning phase, close to all oxidation, cracking, cleavage rate reaches 96 ~ 98%, at the second combustor combustion phases, continue oxidation, cracking, cleavage rate reaches more than 99 ~ 99.5%.Seriation L-type non-phase transformation super heat-conductive pipe heat reclamation type VOC
sincinerator is higher than the cleavage rate of the two-tower type generally adopted in the world now, three-tower type VOCs incinerator, and do not need to install cellular ceramic structure heat storage tank, volume will reduce more than 30%, and construction cost reduces 35-40%.Also reducing mounting cost and maintenance cost, is the high-efficiency environment friendly product of energy-saving and emission-reduction, represents development trend and the direction of VOCs incinerator of new generation.
