Description
Technical field
The present invention relates to a kind of air cleaning unit, especially for the air cleaning unit of removing airborne pernicious gas.
Background technology
Usually said air pollution can be divided into pernicious gas (as sulfur dioxide, carbon monoxide, formaldehyde, benzene compounds etc.) and can suck particle two big classes, remove the airborne particle that sucks and can adopt methods such as filter, electrostatic precipitator, remove airborne pernicious gas and approximately can be divided into following several according to prior art:
Chemiadsorption: use specific chemical agent and airborne pernicious gas irreversible chemical reaction to take place and immobilization, shortcoming is that a kind of medicament can only be effective with one or more pernicious gas compositions, present very strong selectivity, for the more stable pernicious gas of chemical property, normal temperature and pressure is difficult to down remove with chemiadsorption.
The photocatalyst method: this is a kind of relatively more novel method, the subject matter of existence be oxidation reaction the intermediate product thoroughly the time may still be harmful to, even might be stronger than original pernicious gas toxicity.
Chemical oxidization method: typical scheme is to use the strong oxidation oxidation Decomposition pernicious gas of high-concentrated ozone, and the problem of existence is that ozone with high concentration itself is poisonous, and also exists and the problem of the similar intermediate product of photocatalyst.
Physisorphtion: even reach the purpose that purifies air with the airborne pernicious gas of the adsorbents adsorb of the active carbon with physisorption, molecular sieve and so on, physical adsorption techniques is with a long history and ripe, but because the integrated cost height of traditional desorption method, usually only be used for the occasion that the desorption thing has the value recycled, seldom be used for the air cleaning under the general occasion.
Existing civilian or commercial air cleaning unit seldom uses the regenerable sorbent of active carbon, molecular sieve and so on, even if used these regenerable sorbent, owing to do not consider the desorption and regeneration problem of adsorbent in design, just perform practically no function after the saturated absorption of these adsorbents.The manufacturer of some air cleaning units recommends the user to adopt sunlight exposure as the desorption means to adsorbent, no matter and the condition of sunlight exposure is not to have at any time, the obtainable desorption temperature of sunlight exposure institute is pitifully also low, it is extremely insufficient that desorption carries out, the situation that can expect is that the adsorbent behind the sunlight exposure several hrs adsorbs the work dozens of minutes and just adsorbs saturated once more, such desorption time and the ratio of working time are nonsensical technically.
Summary of the invention

Among Fig. 1, the objective of the invention is to realize: a kind of air cleaning unit by following means, at least by air inlet (1), main air blower (2), absorbing unit (3), air outlet (4), and control device (5) constitute, it is characterized in that in main air duct (6), locating to be provided with a heating element heater (7) near absorbing unit (3), form a high-temperature region (8) during this heating element heater heating power in main air duct, this high-temperature region is provided with heat-insulation layer (9); Absorbing unit (3) should be positioned at high-temperature region (8), thereby can be heated to the desorption temperature of setting; Obviously, in the high-temperature region and the high temperature air parts (as absorbing unit (3) and air outlet (4)) of flowing through must adopt heat-resisting design, can operate as normal under the desorption temperature of setting to guarantee it.
Said heating element heater can be heating wire, electrothermal tube, PTC heating pottery etc.Further, said heating element heater can be any element or device that can heat air in the high-temperature region, also can be the element or the device that can directly heat absorbing unit by radiation mode, such as infrared lamp, microwave emitter etc., or a heat exchanger, for example a tube coil type heat exchanger that has high temperature oil to pass through.
Said absorbing unit (3) be to comprise adsorbent, be used for keeping the locus of adsorbent support member, be used for the general name of the connector of necessity of being connected with the device miscellaneous part, but said adsorbent can be active carbon, NACF, molecular sieve and other has the adsorbent of thermal desorption, or the mixture of aforementioned multiple adsorbent.Although select suitable adsorbent, suitable absorbing unit structure to help to improve the performance of device, but the not strict optimization that depends on these factors of the realization of purpose of the present invention is selected, therefore, need not do special qualification to the kind and the absorbing unit structure of adsorbent in this manual.
The setting of desorption temperature should not surpass the tolerable temperature of adsorbent, consider the extra production cost that the design of associated components hear resistance brought when desorption temperature was too high, and the high energy consumption brought of high desorption temperature, desorption temperature can be set in 120～350 ℃, preferably 140～280 ℃, further preferably 160～240 ℃.
Here said control device (5) is the general name of all control elements in the air cleaning unit, generally include but be not limited to: the supply of power supply, blower fan and switch and speed governing, the switch of air door and aperture are regulated, the switch of heating element heater and temperature control, be used for sequentially carrying out the cyclelog of sequence of operations, timer, duty shows, remote control circuit etc., understanding according to this specification under the prerequisite of the present invention, the control device that is easy to utilize prior art to design and share accordingly, therefore in this manual, to the structure of control device, form, principle and working method are not all done detailed explanation and special the qualification.
The course of work of this device is as follows:
State purifies air:
Main air blower (2) drives air and sucks from air inlet (1), during through absorbing unit (3), airborne pernicious gas is adsorbed the adsorbents adsorb in the unit (3), the air of cleaning is discharged from air outlet (4), so continue, just can be with the air cleaning in the space of one of the air cleaning unit place limited relative closure, such as with the air cleaning in a room or the joint compartment.
For the convenience of narrating and understanding, be the space that example is represented a limited relative closure all with the lower part in this specification with a room, and therefore produce in the room in the room outside the concept of space of (atmosphere).
Detachment status:
When the adsorbent in the absorbing unit (3) during saturated or absorption property deterioration, air cleaning unit integral body can be shifted out the room, such as moving to outdoor garden or balcony, give heating element heater (7) heating power this moment, main air blower (2) drives the air heating element heater (7) of slowly flowing through, be heated the back hot-air absorbing unit (3) is added thermal desorption, the pernicious gas that desorption comes out from adsorbent together enters outside atmosphere with hot-air through air outlet (4).More simple, if air outlet (4), absorbing unit (3), heater element (7), main air blower (2), air inlet (1) are arranged according to order from top to bottom, just the characteristic that can utilize hot-air to rise, need not start main air blower (2), only depend on hot-air free convection that absorbing unit is added thermal desorption.
Through after the lasting heating of appropriate time, desorption is finished, and heating element heater (7) stops heating, cools off naturally or forced air cooling under main air blower (2) drives by cross-ventilation, high-temperature region (8) temperature of this device is reduced near room temperature, and so far desorption process is finished.
After this, just air cleaning unit can be moved into the room again and be adjusted to the state of purifying air, just can continue airborne pernicious gas in the adsorption chamber, adsorb saturated after again integral body move to the outdoor desorption that carries out, so circulation, just can in the quite a long time,, purify the air of a room constantly such as the several years.
Obviously, move between indoor and outdoor for the ease of this device, this device should not design too hugely, also can install castor (28) additional on this device so that move.
Shown in Figure 2 is the schematic diagram of a technical scheme of the present invention.
Among Fig. 2, air cleaning unit at least by air inlet (1), main air blower (2), absorbing unit (3), air outlet (4), and control device (5) constitute, it is characterized in that in main air duct (6), locating to be provided with a heating element heater (7) near absorbing unit (3), in main air duct (6), form a high-temperature region (8) during this heating element heater (7) heating power, the sidewall of this high-temperature region (8) is provided with heat-insulation layer (9), absorbing unit (3) is positioned at high-temperature region (8), thereby can be heated to the desorption temperature of setting.Be provided with air door (17) in the air side of absorbing unit (3), be provided with dirty wind exhaust outlet (14) between absorbing unit (3) and the air side air door (17), dirty wind exhaust outlet (14) has following four kinds with outdoor mode of communicating, be the 3rd kind shown in the figure, promptly dirty wind exhaust outlet (14) is communicated with outdoor by blowdown blower fan (16) and blowdown airduct
1. lead directly to outdoor by blowdown airduct (15)
2. be communicated with outdoor by blowdown air door and blowdown airduct (15)
3. be communicated with outdoor by blowdown blower fan (16) and blowdown airduct (15)
4. be communicated with outdoor by blowdown blower fan (16), blowdown air door, blowdown airduct (15).
More than the difference of 4 kinds of modes be, when adopting the blowdown blower fan, can open main air blower when adding thermal desorption, and the blowdown blower fan can form negative pressure in the high-temperature region, effectively avoid revealing because of air door (17) tightly causes the high temperature air that contains pernicious gas inadequately.Such leakage has dual harmfulness: first pernicious gas comes back to indoor, it two are high temperature airs to miscellaneous part is that the harmful effect of indoor environment is not when using the blowdown air door, air cleaning unit has a spot of air and drains into outdoor by the blowdown airduct when purifying the air of a room.
The effect of air side air door (17) is under detachment status, the blocking-up main air duct, prevent that the high temperature air that contains pernicious gas from leaking to indoor, so, the any in principle structure that can block the air channel all can be selected for use, air side air door (17) shown in the figure is made of stationary grid that can slide relatively (12) and movable screen (13), when align in the grid hole (11) on the screen, air can pass through via grid hole (11), air side air door (17) is opened, hole on the screen (11) is when staggering, and air side air door (17) is closed.For illustrated simple and clear, not drawing among the figure drives the mechanism of movable screen (13).
Obviously, in the high-temperature region or as the air door on border, high-temperature region, should adopt heat-resisting design, particularly in the present invention, air side air door (17) is as the border of high-temperature region (8), preferred heat-barrier material or the heat insulation structural of adopting made air-out crosswind door (17), in the air-flow of blocking-up main air duct, can also reduce heat leak by air side air door (17).The harm of such heat leakage is to waste energy and to the undesirable heat influence of miscellaneous part in installing and indoor environment.
The course of work of this device is as follows:
State purifies air:
Air draft crosswind door (17) is opened, if be provided with blowdown blower fan (16) and blowdown air door, both all are in closed condition, main air blower (2) drives air and sucks from air inlet (1), during through absorbing unit (3), airborne pernicious gas is adsorbed the adsorbents adsorb in the unit (3), and the air of cleaning is discharged from air outlet (4) by air draft crosswind door (17).
Detachment status:
, air cleaning unit can be adjusted to detachment status and carry out thermal desorption during saturated or absorption property deterioration when the adsorbent in the absorbing unit (3).
Desorption 1: air draft crosswind door (17) is closed, heating element heater (7) heating power, if be provided with blowdown blower fan (16) and blowdown air door, both all are in opening, also can make main air blower (2) low-speed running to drive air when not having blowdown blower fan (16), the air flow process during desorption is: air inlet (1) → → main air blower (2) → → heating (7) → → absorbing unit (3) → → blowdown air port (14) → → blowdown blower fan (16) → → the blowdown air door → → blowdown airduct (16) is discharged outdoor.From blowdown air port (14) air flow process afterwards, because of aforementioned 4 kinds of blowdown air ports and outdoor mode of communicating difference to some extent.
More simple, with shown in Figure 1 similar, the characteristic that also can utilize hot-air to rise, make hot-air free convection carry out thermal desorption to absorbing unit, can not establish blowdown blower fan (16) this moment, and the air flow process is: air inlet (1) → → main air blower (2) → → heating (7) → → absorbing unit (3) → → blowdown air port (14) → → the blowdown air door → → blowdown airduct (16) is discharged outdoor.
Desorption 2: through after the lasting heating of appropriate time, desorption is finished, and heating element heater (7) stops heating, cools off naturally by cross-ventilation, perhaps uses blowdown blower fan (16) this device of forced air cooling extremely near room temperature, and desorption process is promptly accused and finished.
After this, purifier is adjusted to the state of purifying air, just can continue airborne pernicious gas in the adsorption chamber, adsorbent reaches when adsorbing saturated or absorption property deterioration, be adjusted to detachment status again and carry out desorption, so circulation just can be in the quite a long time, such as the several years, purify the air of a room constantly.
Device shown in Figure 2 and a bigger difference shown in Figure 1 are: this device need not to move just can finish desorption manipulation, thereby can manufacture and design bigger device or adopt wall hanging or other modes to be fixed on indoor, the flexibility ratio of product design is bigger, uses also convenient.
Among Fig. 3, air cleaning unit is at least by air inlet (1), main air blower (2), absorbing unit (3), air outlet (4), and control device (5) constitutes, it is characterized in that in main air duct (6), being provided with a heating element heater (7) near absorbing unit place (3), in main air duct (6), form a high-temperature region (8) during this heating element heater (7) heating power, the sidewall of this high-temperature region (8) is provided with heat-insulation layer (9), absorbing unit (3) is positioned at high-temperature region (8), the two ends of high-temperature region (8) are equipped with air door (17) and (18), at least absorbing unit (3) and heating element heater (7) are positioned at high-temperature region (8), dirty wind exhaust outlet (14) and circulation air port (19) are located at the both sides of absorbing unit (3) respectively, and circulation air port (19) are located at a side of heating element heater (7), the inlet end of blowdown blower fan (16) is communicated with dirty wind exhaust outlet (14), exhaust end then is divided into two-way, lead up to cycle throttle (21) and circulation airduct (20) towards circulation air port (19), and another road is communicated with outdoor by blowdown air door (22) and blowdown airduct (15).
The effect of air door (17) and (18) is under desorption is state, the blocking-up main air duct, prevent that the high temperature air that contains pernicious gas from leaking to indoor, so, the any in principle structure that can block the air channel all can be selected for use, air door shown in the figure (18) for adopt block-shaped and taper main airway (a 6) coupling and can move up and down baffle plate (23) and constitute, during the mobile lofty perch of baffle plate (23), air-flow can pass through from the space between baffle plate (23) and the main airway (6), baffle plate (23) is when moving to low spot, baffle plate (23) agrees with fully with main airway (6), and main air duct is blocked.，
Obviously, in the high-temperature region or as the air door on border, high-temperature region, should adopt heat-resisting design, particularly in the present invention, air door (17) and (18) are as the border of high-temperature region (8), preferred heat-barrier material or the heat insulation structural of adopting made air door (17) and (18), in the air-flow of blocking-up main air duct, can also reduce heat leak by air door (17) and (18).The harm of such heat leakage is to waste energy and to the undesirable heat influence of miscellaneous part in installing and indoor environment.
Its course of work is:
State purifies air:
Blowdown blower fan (16), cycle throttle (21), blowdown air door (22) are closed, open air door in the main air duct (17) and (18), main air blower (2) starts, driving air is sucked by air inlet (1), through main air blower (2) pressurization, the inlet side air door (18) of flowing through successively, absorbing unit (3), air side air door (17), discharge by air outlet (4) at last.
Detachment status:
Desorption 1: blowdown blower fan (16) and cycle throttle (21) are opened, blowdown air door (22) is closed, air door in the main air duct (17) and (18) are closed, main air blower (2) cuts out, heating element heater (7) energising heating, air in the high-temperature region (8) is under the driving of blowdown blower fan (16), according to blowdown blower fan (16) → → cycle throttle (21) → → circulation airduct (20) → → circulation air port (19) → → heating element heater (7) → → absorbing unit (3) → → dirty wind exhaust outlet (14) → → order of blowdown blower fan (16) circulates in high-temperature area, at this moment, if keep blowdown air door (22) crack, can in high-temperature region (8), form negative pressure, can avoid containing the pernicious gas high temperature air and leaking because of the air door in the main air duct (17) and (18) are not closed completely to cause.
Desorption 2: high-temperature area (8) is interior after circulation heating after a while, after reaching the desorption temperature of setting, open blowdown air door (22), close cycle throttle (21), inlet side air door (18) is crack to replenish air, the flow process of air is: inlet side air door (18) → → heating element heater (7) → → absorbing unit (3) → → dirty wind exhaust outlet (14) → → blowdown blower fan (16) → → blowdown air door (22) → → blow-off pipe (15) → → outdoor, heating element heater continuation energising heating this moment can be so that the temperature of absorbing unit remains on the desorption temperature of setting, perhaps be unlikely fall too fast, to guarantee the desorption effect
Desorption 3: close heating unit (7), stop heating, other are identical with step 2, and enter cooling stage this moment, and when treating that each interior parts of high-temperature region (8) are cooled near room temperature, desorption process is promptly accused and finished.
Air cleaning unit after desorption is finished can be adjusted to the duty of air cleaning at any time.
Among Fig. 3, what pass through in the circulation airduct (20) is high-temperature gas, so its surface should coat heat-insulation layer, preferably, circulation airduct (20), cycle throttle (21), blowdown air door (22) all should be arranged in the casing, but for illustrated simple and clear, it is outer and do not coat heat-insulation layer among the figure it to be drawn in casing.
In Fig. 1 to Fig. 3, the air flow of absorbing unit when purifying with desorption is identical, in fact also can be different.With Fig. 1 is example, main air blower can be designed to when purifying with air by above suck, from following discharge, the air flow process of this moment be exhaust outlet → → absorbing unit → → heating unit → → blower fan → → air inlet; During desorption, blower fan counter-rotating, the principle of perhaps just utilizing hot-air to rise, air flow be air inlet → → blower fan → → heating unit → → absorbing unit → → exhaust outlet.Fig. 2 and Fig. 3 are similarly.
Among Fig. 3, heating unit (7) also can be located between air side air door (18) and the absorbing unit (3), accordingly, dirty wind exhaust outlet (14) then should be located at the opposite side of absorbing unit (3), circulating fan (16), blowdown air door (22), blowdown airduct (15), cycle throttle (21), the connection of circulation airduct (20) also is adjusted accordingly and gets final product, if the air flow process that satisfies the desorption stage for according to according to blowdown blower fan (16) → → cycle throttle (21) → → circulation airduct (20) → → circulation air port (19) → → heating element heater (7) → → absorbing unit (3) → → dirty wind exhaust outlet (14) → → order of blowdown blower fan (16) circulates in high-temperature area.
Among Fig. 3, heating unit is located in the main air duct, also can be arranged on any position of circulation wind path, such as the middle part that can be arranged on the circulation airduct.Like this during desorption the air flow process be blowdown blower fan (16) → → cycle throttle (21) → → circulation airduct (20) → → heating element heater (7) → → circulation airduct (20) → → circulation air port (19) → → the dirty wind exhaust outlet of absorbing unit (3) (14) → → blowdown blower fan (16).
At Fig. 1 to the technical scheme of the present invention shown in Figure 3, though with heating element heater " built-in ", but for absorbing unit, the mode that remains " outer heat " heats, promptly be that heating agent heats adsorbent with radiation or with the air, the shortcoming of this mode is that the efficiency of heating surface is lower, and temperature distributing disproportionation is even, absorbing unit (3) is higher near a side temperature of heating element heater (7), opposite side is lower, the method that solves is: the adsorbent in absorbing unit is an active carbon, when NACF or other adsorbents that can conduct electricity, the Hybrid Heating mode that can adopt heating element heater " outer heat " and adsorbent self heating power " self-heating " to combine, can be so that the distribution of absorbing unit temperature inside be more even, therefore the speed of heating and desorption all can improve.For this reason, only need absorbing unit is done corresponding design, comprise and take necessary insulation measures, electrode etc. is set gets final product, as shown in Figure 4.
Figure 4 shows that the structural representation of the absorbing unit of can switch on " self-heating ", among the figure, absorbing unit shell (24) and ventilative aperture plate (27) adopt insulating materials to make, the effect of ventilative aperture plate is to allow air communication to cross and prevent that adsorbent (26) wherein is scattered, pair of electrodes (25) contacts with adsorbent, apply suitable voltage at electrode (25), just have in the adsorbent (26) electric current by and the heating, but said adsorbent can be the adsorbent of active carbon, NACF or other the thermal desorption that can conduct electricity.
Obviously, if at Fig. 1 to the technical scheme of the present invention shown in Figure 3, adopt absorbing unit shown in Figure 4, also can save heating unit, the benefit of doing like this is to have simplified complete machine structure, and desorption rate is fast.
The objective of the invention is to propose a kind of device that can remove pernicious gas in the air, several technical schemes that the present invention proposes have also realized this purpose well, obviously, if in this device, increase in dust removing units, temperature adjustment unit, damping unit, the oxygenation unit one or more, then can on a table apparatus, superpose and realize multiple function.Otherwise, also this device can be superimposed to dust pelletizing system, air-conditioning system, make it to have the function of air cleaning.
Figure 5 shows that on technical scheme shown in Figure 3 basis, increase the system block diagram of dust removing units, temperature adjustment unit, damping unit, oxygenation unit etc.
Among Fig. 5, dust removing units, temperature adjustment unit, damping unit, oxygenation unit are optional increase project, can optionally increase one or more, constitute the device of difference in functionality, for example, increase dust removing units, can constitute the air cleaning unit of full effect, remove airborne pernicious gas simultaneously and can suck particle, increase register, can constitute aircondition, all increase, then constitute Full Featured air purification and regulation device with purification function.
Said temperature adjustment unit is meant the unit that air themperature is regulated, and for example is used to evaporimeter of lowering the temperature or the condenser that is used to heat up.
Said dust removing units is meant removes the unit that can suck particle in the air, can be the filter or the electrostatic precipitator of various structures.
Said damping unit is meant the unit that air humidity is regulated, and for example is used to the evaporimeter that dehumidifies or is used for the fog-spray nozzle of humidification.
Said oxygenation unit is meant the unit that increases oxygen concentration in the air, for example pellicle oxygen-enriching device.
More than said increase correlation function, its effect is not simple stack, for example increasing dust removing units not only can remove dust in air and can suck particle, also can avoid the absorbing unit laying dust, prolong the service life of absorbing unit, be located at the preceding evaporimeter of absorbing unit and can remove moisture too much in the air, prolong the work period of hydrophily adsorbent, the high temperature desorption can also be killed the bacterium and the virus of absorbing unit interception.
Among Fig. 1 to Fig. 3, air cleaning unit is the monomer device, and in Fig. 5, it is indoor to have only the import and export of air to be located at, and the air ports that also can be understood as air cleaning unit feeds indoor by pipeline, and the air cleaning unit body then is installed in outdoor, obviously, such air cleaning unit, its air ports can feed a plurality of indoor by pipeline, Figure 5 shows that " the center air purification adjusting device " of a kind of being similar to " central air-conditioning ".
Fig. 1 to Fig. 3 and technical scheme shown in Figure 5, owing to must there be the regular hour to be used for the desorption of absorbing unit, so its air cleaning process is interrupted, Fig. 6 and Figure 7 shows that a kind of center air that can continuous operation purifies adjusting device
Among Fig. 6, main air duct is divided into 2 or 2 above branch roads, shown in the figure be 2, each branch road is equipped with and is similar to Fig. 3 or high-temperature region shown in Figure 5, and is that heat is isolated between each high-temperature region, to avoid heat affecting each other, like this, the different branch roads desorption time that can stagger, any moment can guarantee that all at least one branch road is in the purification state, whole device just can the continuous purification air.Unillustrated other unit on the main air duct are referring to Fig. 5.
Among Fig. 7, main air duct is divided into 2 or 2 above branch roads, shown in the figure be 2, each branch road is equipped with and is similar to Fig. 3 or high-temperature region shown in Figure 5, shared same blowdown blower fan of a plurality of branch roads and heating element heater, and blowdown blower fan and heating element heater are arranged to an independent high-temperature region, structure that so just can simplification device.Equally, be that heat is isolated between each high-temperature region, to avoid heat affecting each other, like this, and the different branch roads desorption time that can stagger, any moment can guarantee that all at least one branch road is in the purification state, whole device just can the continuous purification air.Unillustrated other unit on the main air duct are referring to Fig. 5.
Sum up:
