Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1 tower body, 2 exhaust gas inlet, 3 clean air outlets, 4 access holes, 5 porous plates, 6 active carbon filtering layers, 7 ground floor demisters, 8 second layer demisters, 9 nozzles, 10 spray liquid casees, 11 spray liquid pumps.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of biological activated carbon deodorizing tower, comprise tower body 1, exhaust gas inlet 2 and clean air outlet 3, described exhaust gas inlet 2 is placed in sidewall bottom tower body 1, purified gas outlet 3 is placed in tower body 1 top, described porous plate 5 is placed in tower body 1 inner lower, is equipped with active carbon filtering layer 6 on porous plate 5; Described nozzle 9 is arranged at active carbon filtering layer 6 top; Ground floor demister 7 and second layer demister 8 is equipped with respectively between described nozzle 9 and purified gas outlet 3.Described spray liquid case 10 is connected with the nozzle 9 be arranged in tower body by spray liquid pump 11.Described tower body 1 sidewall is equipped with access hole 4.Described nozzle 9 is transversely equidistant setting in tower body 1.The utility model is provided with two-layer demister, can ensure except fog effect well, the better effects if purified air, in addition, porous plate 5 of the present utility model can according to different needs, selecting different porous plates 5, specifically, is the porous plate 5 selecting different radii, and then can purify air better, another effect of porous plate, can support active carbon filtering layer 6, make the area of active carbon filtering layer larger.Access hole 4 is arranged on the both sides of tower body, when needs overhaul, can open access hole 4, makes it more to facilitate.
The utility model in the course of the work, gas with foreign flavor is concentrated by exhaust gas inlet 2 and is delivered to biological activated carbon deodorizing tower after gathering system is collected, foul smell enters moistening, porous by porous plate 5 and is full of the active carbon filtering layer 6 of active microorganism, active carbon is utilized foul smell Molecular Adsorption to be got off, recycling deodorizing biology absorbs and degradation function foul smell molecule, the feature little in conjunction with microbial cell individuality, surface area is large, adsorptivity is strong, metabolic type is various, decompose after smell substance absorption, such as, by H
2s is oxidized to SO under the effect of sulfuration bacterium
4 2-, by NH under the effect of nitrifier
3be oxidized to NO
3-, organic bad smell biological is oxidized to CO
2and H
2o, makes active carbon obtain constant regeneration, recovers the function that it absorbs foul smell molecule while microbial decomposition oxidation odorous substance.Gas after active carbon layer adsorption treatment, after moisture removed by ground floor demister 7 and second layer demister 8, is discharged by clean air outlet 3.Spray liquid is sprayed into active carbon layer by nozzle 9 by spray liquid pump 11 continuously or regularly, for microorganism provides required moisture, nutriment, maintains PH in tower.
Microorganism peculiar smell control procedure is divided into three steps:
The first step: activated carbon surface is coated with water layer, at superficial dissolution after the chemical substance in foul smell contacts with filtrate, and be liquid phase from gas phase conversion, the cell be beneficial in active carbon further absorbs Sum decomposition.In addition, the porous of active carbon makes it have the specific area of super large, makes gas, liquid two-phase has larger contact area, increase effectively gas chemistry material transfer spreading speed in the liquid phase.Therefore water-soluble process of osmosis is a physical action process in fact, transmission diffusion at a high speed means that the concentration of foul smell can be down to extremely low level rapidly by filtrate.
Second step: the smell component in the aqueous solution is by microorganism adsorption, absorption, decomposition, and smell component is transferred in microbial body from water.
3rd step: the obligate bacterium cultivated in active carbon (the process bacterial classification obtained according to the type screening of odor source) will take pollutant as food, be the nutriment of self contamination transform, the elements such as carbon, hydrogen, oxygen, nitrogen, sulphur are made to be converted into free state from the form of compound, enter the repeats itself process of microorganism, thus reach the object of degraded.Meanwhile, the microorganisms such as obligate bacterium can realize again self reproductive process, when reaching balance as the pollution compound of food and the nutritional need of obligate bacterium.
Biological activated carbon deodoration system utilizes fixing microorganism on the activated carbon to go to decompose the odorant destroying and be present in air.Growth of microorganism is in the biomembrane or the liquid phase being suspended in around active carbon of activated carbon surface.The bond area that these active carbons provide microorganism larger and extra nutrient supply.When air-flow is by filter bed, the pollutant in gas phase absorb by the biomembrane on active carbon and be attached to activated carbon surface, and carry out biological decomposition at this place.
Biological activated carbon deodorizing tower is generally applicable to process low concentration and a large amount of waste gas, has preferably economy and treatment effect.Meanwhile, polluting species must be decomposable asymmetric choice net and avirulent, has the low-molecular-weight of singly-bound and the good organic compound of dissolubility is the species that in biological treatment, removal effect is best.Biological activated carbon deodorizing tower is applicable to eat, and kitchen is discarded, the process of industrial organic exhaust gas, house refuse foul smell etc.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
