Description
Technical field
The present invention relates to a kind of industrial waste-gas purifier and application, particularly sewage-farm waste gas directly carries out the waste gas purification apparatus and the application of purified treatment, removal odor pollutant.
Background technology
In industrial processes, waste gas needs emptying, some are poisonous, harmful substance enters atmosphere thereupon, the gas that particularly contains odorant, meeting severe contamination surrounding enviroment, biology growth and health are worked the mischief, and along with the progress of social civilization, the requirement that people administer pernicious gas grows to even greater heights.Along with development of science and technology, the waste gas purification technical merit is improving constantly, at present, administer contain method that odorant pollutes have multiple, as firing method, absorption method and bioanalysis or the like.Biological purifying process (as CN97121666) has removal efficiency height, advantage that operating cost is low, obtains paying attention to and using.
Prior biological removes device and adopts forms such as tower, case, jar usually, as the described biological packing tower of CN97211331, the described shell structure waste gas purification apparatus of CN98251836.6.Above-mentioned waste gas purification apparatus need produce the place to waste gas and carry out closed processes, so that collect waste gas, simultaneously, must dispose the waste gas guiding system, thereby gas line, blower fan and other relevant device need be set, thus increased investment, increase floor space, power consumption and operating cost.The main feature of biological purifying process need generally need be lower than 500h than carrying out under the low-speed
-1, and other physical chemistry method such as catalytic fuel etc., gas space velocity can reach 10000h
-1More than.This just makes unit scale that biological clarification needs too big (unit scale and air speed are inversely proportional to), and plant investment, during-operation service, floor space etc. all become serious limiting factor.In addition, the employed filler common intensity of biological clarification is lower, and voidage is less, and need under the condition of more water content and operate, it is bigger therefore to operate pressure drop, and increases along with the increase of the duration of runs, this will increase power consumption, and influence runs well, and purifying rate also reduces greatly.CN01106039.5 is described to be provided with a plurality of biological cleaning filler units on the seal cover of sewage-farm, device is decomposed into a plurality of small-scale operating units on a large scale, has solved problems such as occupation of land, pressure drop be big to a certain extent.If but adopt a fairly large number of little operating unit, and equipment investment increases greatly, and running, maintenance and management is very loaded down with trivial details.If adopt the big operating unit of negligible amounts, then equipment scale is bigger, can't be arranged on the seal cover, has the common weak point of above-mentioned biological purification plant simultaneously.And, this apparatus structure complexity, fabrication and installation and operation are all complicated.Problem on the above-mentioned engineering that the prior art biological purification method exists has seriously restricted its commercial Application in waste gas purification.
Summary of the invention
At the deficiencies in the prior art, the invention provides the waste gas purification apparatus that the place takes place a kind of waste gas.This appliance arrangement is simple in structure, need not to be provided with the waste gas guidance system, power consumption is few.
Exhaust gas biological purifying device of the present invention comprises the spray assembly on biologic packing material layer assembly and the biologic packing material layer assembly, the biologic packing material layer assembly comprises a packed bed body or a plurality of side by side packed bed body, the filler of working load microorganism in the packed bed body constitutes whole biological cleaning reaction zone continuously.The biological cleaning reaction zone accounts for 30%～150% of waste gas generation device area, is preferably 50%～100%.
Leacheate collection assembly (liquid collecting assembly) can be set under the biologic packing material layer, and the liquid collecting assembly is arranged on the packing layer bottom, collects that spray liquid is all or part of to recycle or discharge processing, can adopt conventional ventilation liquid collecting structure.
The covering assembly can be set on spray equipment, hide assembly and be arranged on the spray assembly, can afforest, play effects such as attractive in appearance, collection rainwater.
The oil removing assembly can be set under the liquid collecting assembly, and the waste gas generation device at producing mist of oil removes the mist of oil in the waste gas.
The maintenance inlet of waste gas generation device is set, to make things convenient for the maintenance of equipment.
The application of exhaust gas purification and treatment device of the present invention in purifying various waste gas generation devices particularly purifying various treatment tanks, handling the application in the generation waste gas.
The present invention is according to the biological deodorization process characteristic, utilize waste gas take place the place building structure, hide assembly, liquid spraying assembly and filling batch assembly, liquid collecting assembly and oil removing assembly by being provided with, place waste gas to take place on the place, with biological deodorization, airtight source of the gas, collect waste gas, greening environment, hide rainwater to reduce function such as sewage quantity in one, can obtain effects such as desirable purifying exhaust air, greening environment.For producing the plant area that exhaust device is concentrated,, can greatly improve and beautify the local environment situation as the sewage-farm of large enterprises.Apparatus of the present invention are simple in structure, floor space is little, reliable, power consumption is few, low and the greening environment of operating cost, be applicable to the industrial waste gas purifying processing,, directly purify, remove the waste gas purification processing of stench composition especially for taking place on the place at waste gas.
