Description
Technical field
The utility model relates to a kind of biological deodorizing device of removing foul odour in the industrial tail gas, is specifically related to the bio-trickling filter of the organic foul smell of a kind of novel decomposition.
Background technology
VOC (VOCs) is one big type of gaseous organic pollutant, mainly is meant at the normal temperature saturated vapor pressure to be about greater than 70Pa, and boiling point is less than 260 ℃ organic compound under the normal pressure.VOCs is of a great variety, and it is wide to distribute, and toxicity is big.The VOCs source exhaust gas is extensive, and under the intense UV rays effect, photochemical reaction takes place for VOCs and nitrogen oxide, hydrocarbon etc., generates photochemical fog; The infrared ray that absorbs terrestrial surface radiation causes greenhouse effects; Halohydrocarbon VOCs also can damage the ozone layer and form the ozone cavity, and some VOCs also has three causing property (carcinogenic, aberration inducing, cause breakthrough) in addition.The VOCs exhaust emission is increasingly extensive, is on the rise.Its not only serious harm existent environment of people, and do not encroaching on the healthy of the mankind all the time.
In the market the improvement of organic odorant is generally adopted the washing of two-stage void tower or adopted large-area bio-absorbable pond to decompose; More than two kinds of methods, the former can't take out the odorant composition, wastes a large amount of water sources; Cause secondary pollution; The latter can't realize for a long time the absorption to odorant, because caking and the big gas distribution inequality of area cause the system can't ordinary production easily, takies the large-area production land used of plant area.
Summary of the invention
The purpose of the utility model just provides the bio-trickling filter of the organic foul smell of a kind of novel decomposition; The utility model can absorb and decompose stench tail gas, and flushing water can recycle again, and floor space is little, and vent gas treatment efficient is high.
The bio-trickling filter of the organic foul smell of a kind of novel decomposition of the utility model; Has tower body; The tower body top has clean gas outlet, and the tower body bottom has waste gas inlet, has waste water discharge opening at the bottom of the tower; In tower body, be provided with several layers porous aggregate bed, spray head is being housed on the tower body above the superiors' packed bed; Spray head down is housed on the tower body below the orlop packed bed; A side is provided with the biological fluids circulatory pool at the bottom of tower, the other circulating pump that is provided with of circulatory pool; Outlet port at the bottom of the said tower is respectively with circulatory pool, circulating pump and be connected with pipeline between the spray head up and down and form closed circuit.
Be provided with upper, middle and lower-ranking porous cascade ring packed bed in the said tower body altogether, the packing layer thickness of every layer of packed bed is 600-1000mm, and spacing is 1000-1500mm between every layer of packed bed, and the cascade ring packing material size is 50-100mm.
The operation principle and the process of the utility model are: the biological fluids pond is set outside tower, and initial start stage will be by organic matter acclimated microorganism bacterial classification inoculation in biological liquid pool; Through circulating pump biological fluids is squeezed in the tower, spray and descend, incorgruous mobile with the VOCs that gets in the tower; Microorganism utilizes the organic substance that is dissolved in liquid phase, carries out the metabolism breeding, and is attached to filling surface; Form microbial film, accomplish the bio-film colonization process, water outlet is gone into circulatory pool through tower bottom flow again; And regularly in biological liquid pool, replenish certain biological nutrient liquid, and waste gas gets into from the waste gas inlet that drips filter tower bottom or side setting, the process spraying cooling absorbs from going up earlier down; Liquid and gas flow with the mode of counter current contacting in the packed bed of porous, through the porous aggregate bed, the organic matter in the gas phase through with packing layer in after liquid phase fully contacts; Transfer to liquid phase, behind the waste gas process multilayer packed bed, its organic compound is absorbed, decomposes; Waste gas after the purification is then discharged from the cat head clean gas outlet, VOCs clearance >=85% in the waste gas of being discharged.
The utility model compared with prior art has following characteristics:
1. vertical type cylinder shape tower is simple in structure, and the porous aggregate bed divides wind even, and biologic packing material does not lump, and a filter tower floor space is little;
2. the bacterial classification that adopts is provided by Zhengzhou University's environment and ecological Studies, bacterial classification optimization intensity height, and the ability that eliminates the unusual smell is strong, can high temperature resistant (≤55 ℃), can breed voluntarily, anti impulsion load is big;
3. utilize tower outer circulation loop, the biological nutrient liquid in the biological liquid pool is regularly intermittently replenished in tower, keep biological high activity in the tower;
4. the waste gas of handling through the utility model, wherein VOCs clearance >=85%.
The utility model is mainly used in the improvement of all kinds of organic exhaust gas such as the component complicacy that produces in petrochemical industry, fermentation, pharmacy, tobacco, food, feed, fertilizer, synthetic material, garbage disposal, drying sludge, sanitary sewage disposal or the like the industrial processes, breath malodor.
