Description
Technical field
The utility model relates to retracting device, is specially a kind of ammonia recycling device.
Background technology
A kind of ammonia recycling device is applied to the retracting device that high-concentration ammonia nitrogenous wastewater is processed rear ammonia.During high-concentration ammonia nitrogenous wastewater is processed, ammonia passes through gas and water separator, make ammonia escape dewatered constraint, blown in the air, but ammonia has corrosion and spread effect to the skin histology of contact, can absorb the moisture in the skin histology, makes the histone sex change, and make the tissue fat saponification, destroy membrane structure.The solubility of ammonia is high, stimulates and corrosiveness so mainly the upper respiratory tract of animal or human's body is had, often be attracted to mucocutaneous and the eye conjunctiva on, stimulate and inflammation thereby produce.Can benumb respiratory tract cilium and infringement mucous epithelium tissue, make pathogenic microorganism be easy to invade, weaken human body to the resistance of disease.Ammonia sucks human body with gas form usually, and ammonia easily enters blood by alveolar after being inhaled into lung, is combined with hemoglobin, destroys fortune oxygen function.So it is necessary that Ammonia recovery is recycled, and also is feasible.
The utility model content
The technical problem that the utility model solves is to provide a kind of ammonia recycling device, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of ammonia recycling device, comprise primary amine gas absorption tower, secondary amine gas absorption tower, cyclic water tank, circulating pump one, circulating pump two and hand-hole, be connected by the ammonia carrier pipe between described primary amine gas absorption tower and the secondary amine gas absorption tower, be connected by circulating line between described secondary amine gas absorption tower and the circulating pump two, described circulating pump two and circulating pump one are connected to the two ends of described cyclic water tank by pipeline, described circulating pump one is connected with primary amine gas absorption tower by circulating line.Be equipped with two hand-holes on primary amine gas absorption tower and the secondary amine gas absorption tower.
Described secondary amine gas also is provided with blowdown stack and rainhat on the absorption tower, and described blowdown stack is installed on the described secondary amine gas absorption tower, and described rainhat is installed in the top of described blowdown stack.
Described cyclic water tank also is provided with mouth for subsequent use, glass-tube liquid level meter and running water entrance, and described mouth for subsequent use is located at the top of described cyclic water tank, and described glass-tube liquid level meter and running water entrance are located at the right-hand member of described cyclic water tank.
Also be provided with the weak aqua ammonia delivery pipe on the described circulating line, the bottom of described weak aqua ammonia delivery pipe also is connected with sampling nozzle.
