The beneficial effects of the utility model are:
1, this utility model biofiltration process for purifying device comprises one-stage water wash cascade filtration.Float in foul smell and gas soluble in water are removed in washing, ensure that foul smell keeps certain humidity to enter into biofiltration section simultaneously.Moistening foul smell enters into biofiltration section, for biological bacteria breeding nutrient substance is provided, thus foul smell molecule is degraded and changes into Organic substance, carbon dioxide and water, last qualified discharge.
2, effectively can increase gas-to-liquid contact, gas is fully reacted with microorganism, raising purification efficiency.
3, in aiutage, be provided with demister, demister, near aiutage, solves the problem that exhaust steam moisture is excessive.
On the basis of technique scheme, this utility model can also do following improvement.
Further, described prewashing assembly comprises circulation fluid case and collection conduit, and described collection conduit partially passes through described biofilter body, is connected with described circulation fluid case, and described circulation fluid case is connected with described biological treatment component.
Further, described biological treatment component comprises one-level spray system, wrong gas medium layer, plural secondary spray system, compounded mix layer, gas distribution supporting plate and perforation cloth air flue, described one-level spray system is arranged on the roof of described biofilter body, described wrong gas medium layer is between described one-level spray system and described circulation fluid case, described secondary spray system is successively on the roof being arranged on described biofilter body side by side, described gas distribution supporting plate be arranged on described biofilter body middle and lower part, and described compounded mix layer is between described secondary spray system and described gas distribution supporting plate, one end of described perforation cloth air flue communicates with described one-level spray system, the part in the horizontal of described perforation cloth air flue is positioned at the bottom of described gas distribution supporting plate, described aiutage communicates with described secondary spray system.
This utility model have employed the compound action of Liquid Absorption and biological treatment.First foul smell is absorbed selectively by liquid (absorbent) and forms combined sewage, then by the effect of microorganism by contaminant degradation wherein.
Detailed process is: be first fixed on the filler of compounded mix layer by the extraordinary microorganism species of artificial screening, when dusty gas is through the filling surface initial stage, those microorganism species of nutrient source can be obtained from dusty gas, in suitable temperature, (optimum temperature of biofiltration is 20 DEG C ~ 37 DEG C, but within the scope of 5 DEG C ~ 65 DEG C, biofiltration all can normally run), (humidity of bed body, according to the difference of host material, should remain on 20% ~ 60% to humidity.If bed body humidity is too low, not only in wet bed, biological activity reduces, and also can cause the short stream of foul smell, affect deodorizing effect further), (the optimum pH value of most growth of microorganism is all in neutral range for pH value.When pH value lower than 3.2 time, removal efficiency significantly declines, and when pH value is higher, its removal efficiency is basic irrelevant with pH) etc. under condition, will be grown fast, be bred, and be formed biomembrane at filling surface, when foul smell is by therebetween, by microorganism adsorption and degraded after Organic substance is absorbed by the water layer of biofilm surface, the water being purified regeneration is reused.
The essence of pollutant removal is by antimicrobial absorbent, metabolism and utilization using foul smell as nutrient substance.This process is the process of the mutual coordination of microorganism.
