Description
Technical field
The present invention relates to a kind of reactive evaporation device for reclaiming ammonia in sewage, belong to chemical mechanical equipment field.
Background technology
One kind can be produced NH is contained in chemical process4 +Industrial wastewater, this waste water can not discharge directly, it is necessary to pass through
Qualified discharge after treatment is crossed, and common processing method is plus alkaline solution is neutralized, such as quick lime, calper calcium peroxide, hydrogen-oxygen
Change sodium, potassium hydroxide etc., generate NH3, neutral salt etc., separate NH by the measure such as being aerated3.Patent No. ZL02112729.8 is disclosed
A kind of processing method of high-concentration ammonia nitrogenous wastewater, successively to added in waste water alkaline complexing agent quick lime and calper calcium peroxide and
NaOH, sodium perborate and denitrifier, are aerated after stirring reaction, are eventually adding flocculant, sedimentation separation.But the method
It is made up of multistep reaction and aeration, step is more, is unfavorable for operation.ZL201520604433.8 discloses a kind of from ammonia-containing water
The complexes of middle high efficiente callback ammoniacal liquor, the evaporator of the device carries out heating evaporation using conduction oil to ammonia-containing water, does not have
Aerator, is unfavorable for the separation of ammonia nitrogen.ZL201320516033.2 discloses a kind of high ammonia-nitrogen wastewater treatment and reclaims ammoniacal liquor
Device, including adder-subtractor, blender, prefilter, the waste water pump being connected with high ammonia-nitrogen wastewater pipeline, are connected by road and exchanged heat
Device heated material and by vacuum come ammonia nitrogen removal, the device adds alkali and ammonia nitrogen removal separately to process, and step is more, and there is vacuum
The shortcomings of deamination causes ammonia easily to be escaped by vavuum pump.
The content of the invention
It is an object of the invention to provide a kind of reactive evaporation device for reclaiming ammonia in sewage, it is provided with gas distributor and steam adds
Heat pipe bundle, the effect of gas distributor is not only in that and is sufficiently stirred for sewage and aqueous slkali, accelerates reaction process, Er Qie
Can be by NH in its bubble for being formed3Separated with sewage, prevented it from being effectively dissolved in the water, while in the rising of bubble
During by NH3Gas takes away liquid level, and steam-heating pipe beam is carried out its role is to sewage is heated into certain temperature and alkali
Reaction, under heating and gas distributor ventilation bubbling stirring action, reaction is not only rapid, and conversion ratio is greatly carried
Height, meanwhile, react the NH of generation3At relatively high temperatures, its solubility in water is substantially reduced.
The reactive evaporation device of ammonia in a kind of recovery sewage, including：Housing, lye import, containing NH4 +Wastewater inlet, gas point
Cloth device, steam-heating pipe beam, support, liquid level gauge mouthful, outlet of sewer, temperature-measuring port, gaseous phase outlet, pressure tap, relief valve port；Housing
Side is provided with lye import, and opposite side is provided with temperature-measuring port, and housing bottom is provided with containing NH4 +Wastewater inlet, liquid level gauge mouth, sewage go out
Mouthful, case top is provided with gaseous phase outlet, pressure tap, relief valve port, support is provided with housing, and steam-heating pipe is set on support
Beam, the lower section of gas distributor steam-heating pipe beam again.
Wherein, gas distributor is made up of 6~8 straight tubes arranged in parallel, and every straight tube position directed downwardly is provided with a row
Gas distribution holes, the effect of gas distributor is not only in that and is sufficiently stirred for sewage and aqueous slkali, accelerates reaction process, and
And be that its bubble for being formed can be by NH3Separated with sewage, prevented it from being effectively dissolved in the water, while in bubble
By NH in uphill process3Gas takes away liquid level.
Wherein, steam-heating pipe beam by 6~8 groups of set of heat exchange tubes into being evenly distributed on support.Its role is to by sewage
It is heated to certain temperature and alkali is reacted, under heating and gas distributor ventilation bubbling stirring action, reacts not only fast
Speed, and conversion ratio is greatly improved, meanwhile, react the NH of generation3At relatively high temperatures, its solubility in water is significantly
Reduce.
Equipment operation principle：NH will be contained4 +Sewage by containing NH4 +Inside wastewater inlet injection reactive evaporation device, filling
To a certain amount of rear unlatching steam and compressed air, while to aqueous slkali is filled in equipment, in steam heating and compressed air stirring
Under effect, the NH in sewage4 +It is swift in response with alkali and generates NH3, NH3Absorption tower is sent to by aeration to be absorbed, it is reacted
Sewage is sent to Sewage Disposal and is processed.
In sum, NH is contained4 +Sewage by after the treatment of ammonia reactive evaporation device of the present invention, will can not only generate
NH3Utilization is effectively separated, and by reacting the NH in sewage4 +Subsequently located after dropping to a very low content
Reason, greatly reduces cost of sewage disposal, and certain economic benefit is brought to enterprise.
