The present invention mainly utilizes hydromechanical relative theory, gas mixes in pipeline with absorption liquid, after mixing with gas, absorption liquid passes through pipeline, at this moment gas-liquid two-phase is big with the tube wall contact-making surface, contact surface liquid constantly obtains cooling, reach efficient chemical exchange reaction, the fierce collision of gas-liquid is so that after gas-liquid fully mixes, along with the gravity effect of liquid falls into cyclic water tank.
Workflow is as follows: the ammonia tail gas of band dust enters in the gas buffer jar under the effect of vacuum, make dust follow gas to separate, pure then ammonia continues to carry out secondary water washing in the water tank that volatilization enters the vacuum unit, because the liquid in the water tank constantly heats up under the ringing of water pump, this moment, ammonia was water insoluble, continuing evaporation and enter first absorption tower, is that absorption liquid absorbs with water.Ammonia in the process that water absorbs along with the raising of absorption strength, the temperature of absorption liquid can be along with rising, in order to ensure assimilation effect, so absorption liquid is fully absorbed with cooling water circulation cooling back, the gas that part does not absorb fully enters second absorption tower to be continued to absorb, the gas that was absorbed subsequently enters the 3rd absorption tower again, this moment, the concentration of ammonia was very low, because gas and liquid are also being absorbed by the water circulation, so volatility is very low, the gas of discharging has been pure air relatively, and entering the final gas of discharging of absorbent charcoal adsorption tank absorption again is pure air basically.When the ammonia concn in first absorption tower reaches capacity, it is squeezed into finished product storage tank, simultaneously the ammoniacal liquor of relative high concentration in second absorption tower is squeezed into and continued in first absorption tower to absorb, the low concentration ammoniacal liquor of the 3rd absorption tower mother liquor tank is squeezed into second absorption tower continue the circulation absorption, in the 3rd absorption tower circulating tank groove, inject clear water and continue to absorb.The circulation that goes round and begins again thus absorbs, and finally reaches recovery ammoniacal liquor, the effect of emission compliance, and promptly the economic benefit of Chuan Zaoing makes environment obtain protection again.
