Description
Technical field
This utility model relates to exhaust-gas treatment field, refers specifically to a kind of biofilter for exhaust-gas treatment.
Background technology
The rise of chemical industry and various manufacturing enterprise in recent years, also result in serious environmental pollution while providing material demand for society.The industrial organic exhaust gas of high concentration is at present only taken purified treatment by China, frequently with method be Production by Catalytic Combustion Process, absorption process, absorption method etc.；For the organic exhaust gas of low concentration, this several method complex process, operating cost is high, and biological waste gas purification technology is compared with traditional high-concentration organic waste gas purification method, not only equipment is simple, low cost, and can be greatly improved the clearance of organic exhaust gas.Meanwhile, the organic exhaust gas of high concentration is also had higher purification efficiency by biofilter.
Bioanalysis refers to and heterotroph Microorganism incubation is attached to porous medium filling surface, under moistening environment, makes contaminated air first contact with water, and organic pollution is diffused into biomembrane by air film under the effect of concentration difference and is absorbed by Institute of Micro-biology.Harmless compound such as CO2, H2O and neutral salt finally it is degraded to by the microorganism continuous metabolism to gas chromatography and some inorganic matter.
But existing biofilter waste gas purification technology causes filler blocking or sink due to the accumulation of filler metabolite after a long time use, and then cause that exhaust purification efficiency reduces.
Utility model content
For the deficiencies in the prior art, this utility model aims to provide a kind of biofilter for exhaust-gas treatment, this biofilter is not only simple in structure, put into and operating cost is low, and can solve the problem that the accumulation due to filler metabolite after a long time use existing in prior art and cause filler blocking or problem of sinking, greatly improve exhaust purification efficiency.
For solving the problems referred to above, this utility model provides techniques below scheme:
A kind of biofilter for exhaust-gas treatment, including filtering ponds, filler and spray system, described spray system includes microbial liquid circulatory pool and spray equipment, described spray equipment includes one end and stretches into the feed tube in described microbial liquid circulatory pool and one end is stretched into the shower in described filtering ponds and connects the pump of described feed tube and shower, described shower includes transfusion supervisor and is responsible for the first spray arm being connected and stretching in described filtering ponds and the second spray arm with described transfusion, described filler is located in described filtering ponds, described filler includes spaced ground floor filler and second layer filler, the bottom of described filtering ponds is provided with exhaust gas inlet；The first described spray arm is between described ground floor filler and second layer filler, and described second spray arm is located at the top of second layer filler.
Further, described ground floor filler includes the wood flour as microorganism attachment medium and activated carbon and the hollow ball as bracing frame；Described second layer filler is general bio-filter stuffing.
Further, the bottom of described filtering ponds is provided with the microbial liquid recovery tube being connected with described microbial liquid circulatory pool.
Further, the first described spray arm and the second spray arm are equipped with shower nozzle.
Beneficial effect: this utility model is not only simple in structure, put into and operating cost is low, and can solve the problem that the accumulation due to filler metabolite after a long time use existing in prior art and cause filler blocking or problem of sinking, greatly improve exhaust purification efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of specific embodiment of the utility model.
Description of reference numerals: filtering ponds 1, exhaust gas inlet 101, ground floor filler 2, second layer filler 3, infuse supervisor 4, first spray arm 401, the second spray arm 402, shower nozzle 5, pump 6, feed tube 7, microbial liquid circulatory pool 8, microbial liquid recovery tube 9, microbial liquid 10.
Detailed description of the invention
Specific embodiment of the utility model is described in detail below according to Figure of description:
With reference to Fig. 1, a kind of biofilter for exhaust-gas treatment, including filtering ponds 1, filler and spray system, described spray system includes microbial liquid circulatory pool 8 and spray equipment, described spray equipment includes one end and stretches into the feed tube 7 of described microbial liquid circulatory pool 8 and one end is stretched into the shower in described filtering ponds 1 and connects the pump 6 of described feed tube 7 and shower, described shower includes transfusion supervisor 4 and the first spray arm 401 and the second spray arm 402 being connected with described transfusion supervisor 4 and stretching in described filtering ponds 1, described filler is located in described filtering ponds 1, described filler includes spaced ground floor filler 2 and second layer filler 3, the bottom of described filtering ponds 1 is provided with exhaust gas inlet 101；The first described spray arm 401 is between described ground floor filler 2 and second layer filler 3, and described second spray arm 402 is located at the top of second layer filler 3；Described ground floor filler 2 includes the wood flour as microorganism attachment medium and activated carbon and the hollow ball as bracing frame；The bottom of described filtering ponds 1 is provided with the microbial liquid recovery tube 9 being connected with described microbial liquid circulatory pool 8, and the first described spray arm 401 and the second spray arm 402 are equipped with shower nozzle 5.
The operation principle of this biofilter: first waste gas is entered in filtering ponds 1 by the exhaust gas inlet 101 of filtering ponds 1, then microbial liquid 10 by first spray the shower nozzle 5 that sprays of arm 401 spray and under, microbial liquid 10 forms one layer of microbial film on ground floor filler 2 surface, waste gas first passes through ground floor filler 2 in the process flowed up, Organic substance and oxygen in waste gas pass through and are transferred into microbial film, thus being decomposed by the microorganisms utilization；Waste gas after ground floor filler 2 purifies enters second layer filler 3, and in this packing layer, waste gas is decomposed purification further；Clean gas after two-layer purifies is directly discharged into air, owing to the bottom of filtering ponds 1 is provided with the microbial liquid recovery tube 9 being connected with described microbial liquid circulatory pool 8, so microbial liquid 10 can reclaim and be again introduced into microbial liquid circulatory pool 8 and be circulated use.
This utility model is not only simple in structure, and puts into and operating cost is low, and can solve the problem that the accumulation due to filler metabolite after a long time use existing in prior art and cause filler blocking or problem of sinking, and greatly improves exhaust purification efficiency.
The above, it it is only preferred embodiment of the present utility model, not technical scope of the present utility model is made any restriction, therefore every any trickle amendment, equivalent variations and modification above example made according to technical spirit of the present utility model, all still fall within the scope of the technical solution of the utility model.
