Description of the drawings
Fig. 1 is the schematic diagram of the present invention；
Fig. 2 is the diagrammatic cross-section of the present invention.
Specific embodiment
The invention will be further described with specific embodiment for explanation below in conjunction with the accompanying drawings：
A kind of evaporator steaming as shown in Fig. 1 to 2 removes ammonia and ammonium salt reclamation vapo(u)rization system, includes evaporator 1,
Heat exchanger tube 2 is equipped in the evaporator 1, be equipped in 1 upper end of evaporator can absorb in evaporator 1 contained ammonia in steam except ammonia
Device 3.
Heretofore described ammonia removal device 3 includes gas gathering mask 31, and pickling system 32 is equipped in the gas gathering mask 31,
32 top of pickling system is equipped with the acid solution of steam entrained with or the demister 33 of mist after removing pickling.
Heretofore described pickling system 32 includes cloth acid disk 321, and acid solution is equipped on the cloth acid disk 321 and is sprayed
Device 322 is equipped with below the acid solution spray thrower 322 and connects acid tank 323.
Pickling system 32 of the present invention is connected with the pickling circulatory system.
The heretofore described pickling circulatory system includes acid solution storage tank, is connected in the acid solution storage tank with a metering pump
It connects, the metering pump is connected with acid solution spray thrower 322, and the acid tank 323 that connects is connected with acid solution storage tank.
