Description
Technical field
The utility model relates to a kind of waste gas recycle device, the waste gas recycle device in particularly a kind of ultra-pure ammonia production system.
Background technology
Ultra-pure ammonia is very important raw materials for production in iron and steel, powder metallurgy, heat treatment, chemical industry, the electronic gas production, but in production, use, there is useless ammonia to exist, its strong impulse smell all can damage and pollute for health and atmospheric environment, therefore, directly enter atmosphere and cause air pollution for fear of a large amount of industrial tail gas that contains ammonia that produces, need to adopt certain method to absorb for the ammonia in the industrial tail gas.
At present be that to absorb ammonia by water spray column device be ammoniacal liquor basically in the equipment of usefulness.
The shortcoming of this kind equipment is: because use neutral water as absorbent, the ammonia that also has a great deal of in the absorption process discharges in air from emptying.And the solubility of ammonia in water is limited, so equipment must be huge, and floor space is many.Can not thoroughly solve the environmental issue of production, use ammonia industry.
Summary of the invention
At the shortcoming of above-mentioned existence, the purpose of this utility model is: propose a kind of ultra-pure ammonia production system waste gas recycle device ingenious, safe and reliable, that can produce continuously and can fully utilize that designs.
The technical solution of the utility model is: a kind of ultra-pure ammonia production system waste gas recycle device, this device comprises absorption tower body and complex acid groove, wherein absorb tower body and be provided with exhaust gas entrance, absorb in the tower body and be provided with three layers of packing layer and twice spraying system, absorb cat head and be provided with blow-down pipe, be provided with the liquid circulation pump that is communicated with the spraying system pipeline in the tower body, liquid circulation pump is provided with the PH measuring cell, and the pipeline that liquid circulation pump comes out from packing layer is provided with fluid sulphuric acid ammonium baiting valve; The complex acid groove is provided with PH analyzer and diaphragm metering pump, the control signal wire of PH analyzer is connected to diaphragm metering pump, wherein diaphragm metering pump carry sulfate liquid to absorption tower body that its pipeline is connected in liquid circulation pump, the holding wire of PH measuring cell is connected to the PH analyzer.
Described exhaust gas entrance enters and absorbs the oblique angle that interior its pipeline of tower body has downward-sloping 30 degree, is convenient to entering of waste gas.
The operation principle of the utility model product is:
The liquid circulation pump that tower body is provided with, sulfate liquid is sprayed by two road spray systems, the useless ammonia that produces from each point, is collided with sulfuric acid mist in the process that gas rises from lower to upper to the exhaust gas entrance that absorbs on the tower body by each road pipe influx, generates ammonium sulfate.The PH measuring cell that the tower body bottom is furnished with sends to the PH analyzer continuously with the acid degree in the liquid, the PH analyzer passes to the sulfuric acid diaphragm metering pump with signal when the approaching neutrality of liquid, the measuring pump starting, ceaselessly sulfuric acid is added to and make in the tower still that circulating fluid remains acidity in the tower, guarantee the normal absorption of useless ammonia.
The beneficial effects of the utility model are: useless ammonia can fully utilize through being absorbed as the industrial sulphuric acid ammonium, eliminates environmental pollution.This appliance arrangement compact conformation, floor space is little, can move continuously.The utility model is widely used in the industry that iron and steel, powder metallurgy, heat treatment, chemical industry, electronic gas have useless ammonia to exist.
