The device has advantages of high absorption efficiency, low equipment investment, convenient operation and no secondary pollution.
Description
(1) technical field
The utility model relates to a kind of gas absorbing device, relates in particular to a kind of ammonia-containing exhaust absorption plant, belongs to technical field of chemical.
(2) background technology
In producing pesticide intermediate isophthalodinitrile process,, therefore in producing tail gas, have and do not participate in the remaining ammonia of reaction owing to be the ammonia excessive response.In order to reclaim and administer the pollution that ammonia causes, domestic enterprise adopts water or acid to absorb the back discharging to this mixed tail gas mostly at present, and the most frequently used equipment is spray absorber.
Absorbing in the ammonia process with acid, there is following point, can produce a large amount of acid mists after adopting single spray absorber to absorb, caused secondary pollution, this just needs the extra cover demister system that increases, and has increased investment.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of absorption efficiency height is provided, and equipment investment is little, and is easy to operate, can not cause the ammonia-containing exhaust absorption plant of secondary pollution.
The purpose of this utility model is achieved in that a kind of ammonia-containing exhaust absorption plant, it is characterized in that it comprises absorption liquid case, absorption tower and spray pump,
Described absorption tower comprises air inlet, packing layer, multihole distributor and spray thrower,
Described air inlet is arranged on the tower wall of bottom, described absorption tower,
Described packing layer is arranged at inner chamber top, absorption tower, and described multihole distributor is arranged at described packing layer below,
Described multihole distributor below is provided with spray thrower, and described spray thrower links to each other with described spray pump outlet by pipeline, and the import of described spray pump links to each other with described absorption liquid case,
Described absorption liquid case is positioned at the bottom on described absorption tower, and is connected with the outlet of described absorption tower,
Described absorption liquid lower box part is provided with discharge opening.
The utility model ammonia-containing exhaust absorption plant, described spray thrower are the two-layer or two-layer above corrosion resistant of the obstruction shower nozzle that do not have.
The utility model ammonia-containing exhaust absorption plant has the following advantages:
When this ammonia-contaminated gas absorption plant moves on the one hand, still get back to the absorption liquid case after absorption liquid pumping spray absorbs tail gas, the gas after the absorption after multihole distributor effectively distributes, is removed acid mist through packing layer again, has avoided secondary pollution.
The characteristics of a maximum of this absorption plant organically combine absorption liquid case, spray absorption system and demister system exactly on the other hand, and are so both easy to operate, also reduced investment simultaneously.
