Description
Technical field
The present invention relates to a kind of waste gas recovering device, be specifically related to a kind of ammonia recycling device.
Background technology
APP is a kind of halogen-free environment-friendly type flame-proof agent of nitrogenous phosphorus structure, and this product degree of polymerization is high, Heat stability is good, and hygroscopicity is little.It is different from the fire-retardant process of Halogen and produces the fire retardation that the expansion carbon-coating reaches heat insulation secluding air, and characteristics such as low cigarette, low toxicity, no molten drop, is a kind of fire retardant of inorganic environmental protection efficiently.Applicable to fields such as plastics, polyester, rubber, various high-grade expanding fire-proof paints.But in the product building-up process, can produce NH
3Volatility waste gas, contaminated environment as not handling discharging, certainly will cause environmental pollution easily.
Usually the processing method of ammonia-contaminated gas has: absorption process and decomposition method.The former mainly is that water or dilute acid soln (sulfuric acid or hydrochloric acid) absorb ammonia-contaminated gas; Make it be converted into ammoniacal liquor, ammonium sulfate or ammonium chloride; Because the restriction of ammoniacal liquor purposes, most enterprises adopt the dilution heat of sulfuric acid absorption process, and isolate the raw materials for production of ammonia sulfate crystal as composite fertilizer through evaporation and concentration, crystallisation by cooling; Accomplish comprehensive utilization, but whole utilization ratio is lower.Latter's decomposition method mainly is the effect through catalyst, and ammonia is decomposed into nitrogen and hydrogen, and still, the processing cost of this method is higher, uses producer few.It is reported; There is company to adopt two sections sprays of clear water absorption process to absorb useless ammonia at present; Decompose ammonium through denitride technology again, because weak influence and the disposal cost height of biological treatment ability makes circulating absorption solution not handle completely effectively; And high-temp waste gas makes the absorption liquid intensification cause the ammonia that is dissolved in the absorption liquid to parse after the repetitive cycling, causes secondary pollution.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of good absorbing effect in order to overcome deficiency of the prior art, the ammonia-contaminated gas treating apparatus that cost is little.
Technical scheme: ammonia-contaminated gas treating apparatus of the present invention; Comprise condensing unit; This condensing unit is connected with the absorption tower, and the bottom is provided with the absorption liquid bath in this absorption tower, and this absorption liquid bath is provided with the Recycling Mother Solution pump; Be provided with the mother liquor riser tubing between this Recycling Mother Solution pump and the top, said absorption tower, internal upper part is provided with three grades of spray equipments on said absorption tower.
Be provided with exhaust blower at top, said absorption tower.
Be provided with elevator pump at said absorption liquid trench bottom, be provided with the magma pipeline between this elevator pump and the centrifuge.
On said absorption liquid bath, be provided with feeding tube and filler pipe road.
Be provided with waste gas at said condensing unit one end and feed pipeline, the said condensing unit other end is fixedly connected with said absorption tower.
Be provided with useless ammonia between said condensing unit and the said absorption tower link and import pipeline, this useless ammonia imports pipeline one end and is located at said absorption liquid trench bottom.
Beneficial effect: the present invention compared with prior art; Its remarkable advantage is: adopt absorption tower and three grades of structures such as spray; Make the absorptivity of ammonia-contaminated gas improve greatly; And cost of investment is less, and the ammonia sulfate crystal of generation can be used as the raw materials for production of composite fertilizer, has played the effect of utilize resources synthetically.
Description of drawings
Fig. 1 is a framework sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Of Fig. 1; Ammonia-contaminated gas treating apparatus of the present invention comprises condensing unit, and this condensing unit is connected with the absorption tower; The bottom is provided with the absorption liquid bath in this absorption tower; This absorption liquid bath is provided with the Recycling Mother Solution pump, is provided with the mother liquor riser tubing between this Recycling Mother Solution pump and the top, said absorption tower, and internal upper part is provided with three grades of spray equipments on said absorption tower; Be provided with exhaust blower at top, said absorption tower; Be provided with elevator pump at said absorption liquid trench bottom, be provided with the magma pipeline between this elevator pump and the centrifuge; On said absorption liquid bath, be provided with feeding tube and filler pipe road; Be provided with waste gas at said condensing unit one end and feed pipeline, the said condensing unit other end is fixedly connected with said absorption tower; Be provided with useless ammonia between said condensing unit and the said absorption tower link and import pipeline, this useless ammonia imports pipeline one end and is located at said absorption liquid trench bottom.Acid ammonium sulfate liquor is transported to the top of packed absorber by the Recycling Mother Solution pump, and ammonia-contaminated gas gets under the solution that absorbs liquid bath from the bottom, absorption tower through condensing unit spray cooling back, carries out bubbling earlier and absorbs; Gas after bubbling absorbs rises and top sprays the circulating mother liquor counter current contacting of getting off along packed absorber again, the ammonia of the remnants in the waste gas is further absorbed, thereby the ammonia content in the gas is reduced to below the discharge standard; After Despumation device enters atmosphere by the exhaust blower that is located at the top, absorption tower with gas, the ammonium sulfate that absorbs in the liquid bath absorbs through continuous circulation, just separates out ammonia sulfate crystal after concentration reaches capacity; These crystal can sink to the absorption liquid trench bottom, through elevator pump magma are entered in the crystallization tank, send into to obtain the by-product solid ammonium sulfate after centrifuge removes mother liquor; And leach to such an extent that mother liquor turns back in the absorption liquid circulating slot, and continue recycle, in this process, need constantly to add the concentrated sulfuric acid; To replenish, keep pH value about 6, simultaneously by the acidity of ammonia neutralization; Because in the absorption process is exothermic reaction; Can evaporate part water,, need to replenish a spot of water in order to keep water balance.The present invention adopts absorption tower and three grades of structures such as spray, make the absorptivity of ammonia-contaminated gas improve greatly, and cost of investment is less, and the ammonia sulfate crystal of generation can be used as the raw materials for production of composite fertilizer, has played the effect of utilize resources synthetically.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
