Description
Technical field
The utility model is related to a kind of gas handling system more particularly to a kind of ammonia exhaust treatment systems.Especially suitable for
Tail gas amount is unstable, and ammonium hydroxide can be with the system of reuse.
Background technology
Currently, the purification method of ammonia mainly has chemical pickling method, cooling water washing method and high-temperature decomposition.Chemical absorption method
It is that one kind being widely used in exhaust gas control, technology maturation is stable, the process of high treating effect.Low temperature washing master
If being sprayed using sub-cooled, ammonia recycles after multiple stage circulation washing.High-temperature decomposition is exactly that gas is introduced calcining furnace
In, temperature is added to 700 degrees Celsius or more, so that ammonia is resolved into NO, CO and vapor, but one-time investment is big, operating cost
Height, it is complicated, overhaul the shortcomings of inconvenient.Most of exhaust emissions are because operating mode is unstable larger to equipment impact, absorbing liquid
Directly as waste liquid by direct emission, it is unfavorable for circular economy industrial.
Invention content
In order to solve the above-mentioned technical problem the utility model is related to a kind of ammonia exhaust treatment systems, it is therefore an objective to which enhancing absorbs effect
Fruit reduces reaction temperature, steady working condition.
A kind of ammonia exhaust treatment system of the utility model for the above-mentioned purpose, including surge tank tank connected are penetrated with buffering
Tower is flowed, the water scrubber being connect with jet stream tower connect pickling tower with water scrubber, and the gas discharge outlet of pickling tower passes through pipeline and chimney
Connection, with tank used for storing ammonia by pipeline connection, pickling tower is connect the liquid outlet of jet stream tower with sulfuric acid dosing tank.
Pipeline is equipped with wind turbine between water scrubber and pickling tower.
The caliber of the air inlet pipe of jet stream tower and water scrubber is more than the caliber of escape pipe.
Shell and tube condenser is equipped in jet stream tower and water scrubber.
External insatiable hunger ammonium hydroxide make-up pump between jet stream tower and water scrubber.
Jet stream tower, water scrubber and pickling tower distinguish external vacuum cycle pump.
Liquid level gauge, thermometer and percentage display are equipped in jet stream tower and water scrubber.
The utility model has the advantages of：Tail gas containing ammonia is after jet stream tower and water scrubber repeatedly cooling water washing, ammonia
Gas, which dissolves in, becomes ammonium hydroxide in water, sulfuric acid scrubbing of the ammonia in pickling tower of volatilization, and fresh tail gas is arranged from pickling column overhead portion
Tracheae is discharged.Ammonia assimilation effect in tail gas is up to 99% or more.Tail gas after absorption does not generate new pollutant, whole
Tail gas is absorbed by water used for cooling tower, and ammonia is converted to ammonium hydroxide recycling, and remaining unabsorbed ammonia sulfuric acid scrubbing is done
The top tail pipe direct emission that net gas passes through tower.Enhance assimilation effect, reduces reaction temperature, steady working condition.The tail gas of discharge
The discharge standard of national defined can be reached.
Description of the drawings
Fig. 1 is the block diagram of the utility model.
In figure：1, surge tank；2, jet stream tower；3, water scrubber；4, pickling tower；5, chimney；6, tank used for storing ammonia；7, vacuum cycle

Specific implementation mode
The technical scheme in the embodiment of the utility model clearly completely retouched with reference to the accompanying drawings and examples
It states.Obviously the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on this reality
It is obtained by those of ordinary skill in the art without making creative efforts every other with the embodiment in novel
Embodiment shall fall within the protection scope of the present invention.
As shown, a kind of ammonia exhaust treatment system of the utility model, including surge tank 1, the jet stream being connect with surge tank 1
Tower 2, the water scrubber 3 being connect with jet stream tower 2 connect pickling tower 4 with water scrubber 3, the gas discharge outlet of pickling tower 4 by pipeline with
Chimney 5 connects, and with tank used for storing ammonia 6 by pipeline connection, pickling tower 4 is connect the liquid outlet of jet stream tower 2 with sulfuric acid dosing tank 10.
Pipeline is equipped with wind turbine 9 between water scrubber 3 and pickling tower 4.
The caliber of the air inlet pipe of jet stream tower 2 and water scrubber 3 is more than the caliber of escape pipe.
Shell and tube condenser is equipped in jet stream tower 2 and water scrubber 3.
External insatiable hunger ammonium hydroxide make-up pump 8 between jet stream tower 2 and water scrubber 3.
Jet stream tower 2, water scrubber 3 and pickling tower 4 distinguish external vacuum cycle pump 7.
Liquid level gauge, thermometer and percentage display are respectively equipped in jet stream tower 2 and water scrubber 2.
The operation principle of the utility model：For reacted complete ammonia using reacting kettle inner pressure as power, ammonia enters ammonia
Gas surge tank, surge tank play the role of the stabilization to follow-up operation air-flow；Eliminate it is unstable to source gas, caused by tolerance
Moment is excessive or hypertonia is influenced caused by follow-up operation stabilization and safety；The impurity in ammonia is collected, is made pure steady
Fixed ammonia is recycled into incident flow tower；It can be pumped and controlled by vacuum cycle by the effect of adjusting vacuum degree and rate of air sucked in required again,
The tolerance into incident flow tower can be controlled, source gas destabilizing factor can be made to be adjusted to stable air-flow and air inlet pressure in this way
Power.Surge tank is connected with low temperature jet flow tower, in low temperature jet flow tower wherein by the suction of ammonia continuous-stable in surge tank.Main profit
With hydrodynamics relative theory, gas is mixed with absorbing liquid in pipeline, and at this moment gas-liquid two-phase is big with tube wall contact surface, contacts table
Face liquid constantly it is fierce collide so that gas-liquid is sufficiently mixed after, form ammonium hydroxide as the gravity of liquid falls into bottom.Jet stream
The caliber of the air inlet pipe of tower 2 and water scrubber 3 is more than the caliber of escape pipe, is micro-positive pressure in tower, to reach the mesh of efficient absorption
's.When ammonia concn is more than 20% in jet stream tower, reuse pipe valve, conveying ammonium hydroxide to tank used for storing ammonia, water scrubber supplement leaching are opened
Washing lotion is to jet stream tower, and when ammonia concn is more than 20% in pickling tower, conveying ammonium hydroxide to tank used for storing ammonia, last tail gas is from pickling tower
Top of tower exhaust pipe is discharged into chimney.
