Description
Technical field
The utility model relates to waste gas recovering device manufacturing technology field, relates in particular to a kind of exhaust gas adsorption device.
Background technology
In the production of the industries such as chemical industry, medicine, printing, coating, packing, all can produce organic exhaust gas, VOC VOCs particularly, VOC (VOC) refers at normal temperatures, the various organic compounds that boiling point is 50 ℃-260 ℃.VOC by its chemical constitution, can be further divided into: alkanes, aromatic hydrocarbons, ester class, aldehydes and other etc.What identified at present has a kind more than 300.Modal have benzene,toluene,xylene, styrene, trichloro-ethylene, chloroform, trichloroethanes, vulcabond (TDI), two isocyanide toluene esters etc.Formaldehyde is also VOC, but formaldehyde is soluble in water, different with other VOCs, indoor wide material sources, and release concentration is also high.Therefore, often formaldehyde and other VOCs are set forth respectively.Except formaldehyde, most VOCs are generally all water insoluble and be soluble in organic solvent.In indoor their concentration separately, be not often very high, but when several VOC are present in room air jointly, its synergy is very important.Because their kinds are many, the concentration of single component is low, is usually used in TVOC and represents VOC total amount in indoor.TVOC weighs the indoor articles such as building interior trim finishing and furniture.To Affecting Indoor Air Quality degree important indicator.At present, need to use organic exhaust gas adsorption device to carry out adsorption cleaning to it, in order to avoid environment is impacted.Current organic exhaust gas adsorption device is comprised of intake valve, adsorption chamber and air bleeding valve, has placed a plurality of absorbing units in adsorption chamber.Its workflow is: organic exhaust gas with pressure enters adsorption chamber through intake valve, sees through the bed of the absorbing unit of discharge side by side and enters adsorption chamber inner chamber, and then the air bleeding valve by adsorption chamber top emits.Organic matter in adsorption process in organic exhaust gas be adsorbed, be trapped in adsorbent bed in, reach the purified treatment of organic exhaust gas.
But because current organic exhaust gas adsorption device is, in adsorption chamber one side, air inlet is set, organic exhaust gas directly enters adsorption chamber from the side, the defect that causes this intake method to exist.First, because the resistance of absorbing unit causes absorption indoor air flow, there is pressure differential, more approach air inlet place pressure higher, from air inlet place more away from pressure lower, particularly evident for the adsorption chamber of placing many absorbing units.Such pressure differential certainly will cause each absorbing unit allocation of the amount of air uneven, and the adsorbance that air quantity is large penetrates greatly and first, and the adsorbance that air quantity is little is little and unsaturated; Secondly, because air quantity inequality causes the utilization rate of adsorbent low and can cause the direct discharge of the organic exhaust gas causing because of partial penetration, serious environment pollution; Again, under this intake method, to enter the gas speed of adsorption chamber many more than 10m/s for organic exhaust gas, and be that air-flow directly purges the carbon bed of absorbing unit, can cause certain breakage and shortened its service life carbon bed, therefore there is the problems such as the adsorption efficiency causing because intake method is unreasonable is low, the adsorbent life-span is short in current organic exhaust gas adsorption device.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of exhaust gas adsorption device is provided, and can reclaim industrial waste gas, prevents that industrial gas emission is in atmosphere.
The utility model for achieving the above object, by the following technical solutions:
A kind of exhaust gas adsorption device, it is characterized in that: comprise the first suction box, the second suction box and axial flow blower, described the first suction box and the second suction box top are communicated with by ventilation shaft, described axial flow blower is arranged on described ventilation shaft, in described the first suction box, be provided with Curved dust suction cloth bag, the entrance point of described dust suction cloth bag is connected with outside, the port of export sealing of described dust suction cloth bag, in described the second suction box, be provided with at least one deck ceramic fibre cellular board, the bottom of described the second suction box is provided with air-introduced machine.
The thickness of described ceramic fibre cellular board is 8-10mm, on it with the cellular through hole being crisscross arranged.The ceramic fibre cellular board of this kind of special construction can adsorb VOCs(VOC), reach the object purifying air.
It is conical that described the second suction box is, and the setting of pyramidal structure can strengthen by the intake of ceramic fibre cellular board, the absorption of the pollutant of being more convenient for.
Described ceramic fibre cellular board is two-layer, and the setting of double-layer structure can either reduce the input of cost, can reach good adsorption effect again.
Described ceramic fibre cellular board is parallel to be placed in described the second suction box, strengthens adsorption area.
Described ceramic fibre cellular board is vertically placed in described the second suction box, and this kind needs the setting of multilayer, is vertically arranged on when guaranteeing that wind speed is fast, is more convenient to cleaning.
The beneficial effects of the utility model are: the utility model is simple in structure, adopt the structure of secondary recovery, the first suction box can be adsorbed on the pollutant of larger particles in discarded on dust suction cloth bag, ceramic fibre cellular board on the second suction box can adsorb VOCs, waste gas absorption is mainly by being coated in hydrophobic type zeolite mesopore molecular sieve on the honeycomb that the resistant substrates such as ceramic fibre make, when large-wind-volume low-concentration waste gas is during by this special structure, six unique side's phase structures of the mesopore molecular sieve of hydrophobic type self, for little molecule VOCs, there is good adsorption effect, short grained VOCs is adsorbed in the duct of zeolite molecular sieve completely, thereby complete the purification of whole waste gas.And thereby special honeycomb makes molecular sieve and the VOCs of Wind Volume have sufficient contact to guarantee that whole absorption link adsorption effect can be up to more than 95%, purified gas can discharge and enter in atmosphere straight.
