Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments.
Referring to Fig.1: a kind of easily to prevent tank used for storing ammonia volatilization ammonia leakage device, including the storage of tank used for storing ammonia 1, dilution water
Tank 3 and buffer unit, the tank used for storing ammonia 1 one outlet is connected with static mixer 4, another outlet of tank used for storing ammonia 1 and
Buffer unit is connected, and an outlet of the buffer unit is connected with dilution water storage tank 3, and the one of the dilution water storage tank 3 goes out
Mouth is connected with static mixer.
In process of production, ammonia is mixed in static mixer with dilution water, obtained mixed liquor is used for
It is out of stock.
In the present embodiment, 1 breather valve 11 is installed on tank used for storing ammonia, breather valve is equipped with exhaust pipe 15, exhaust pipe 15
Outlet is inserted into buffer unit, and buffer unit is surge tank 2, and surge tank is provided with dilution water, and exhaust outlet is inserted into slow
Jar liquid surface 300mm is rushed hereinafter, being because utilizing dilution when the ammonia in tank used for storing ammonia is entered in surge tank by exhaust pipe 15
Water washing ammonia can generate vigorous reaction, can prevent liquid level from acutely floating exhaust outlet insertion liquid level 300mm or less, just
