Abstract
The utility model relates to an imitative-ecological waste gas purification device which is characterized by comprising an imitative-ecological filter bed, a plant liquid washing device and an air draft, wherein the air draft, the imitative-ecological filter bed and the plant liquid washing device are sequentially connected. The device, based on a waste gas purification principle of combining the imitative-ecological filter bed and the plant liquid washing, ensures that the waste gas molecules respectively and completely contact with biological flora and plant deodorant liquid to absorb and decompose the waste gas molecules, and the final reaction products are harmless molecules such as water, oxygen and nitrogen. And the technology, since successful development and putting onto the market, has been widely applied to deodorization in sewage treatment plant, sewage pumping station, refuse landfill, waste transfer station and factory place.
Description
Technical field:
The utility model relates to waste gas purification apparatus, is specifically related to a kind of Ecology waste gas purification apparatus.
Background technology
At present, the spray odor removal that is applied to the occasions such as sewage treatment plant, sewage pumping station, refuse landfill all adopts the chemical washing device, Chinese patent ZL 200820080269.5 discloses a kind of four segment combined biological deodorizing devices, comprises the parts such as housing, spray pump, gas pipe, inert filler layer, active filler layer, spray nozzle, floss hole, overflow pipe, blow-down pipe.The shortcoming of such device is: 1, this invention is comprised of two-stage washing and two-stage absorption, and it is larger that odor removal takes up an area the space, complex operation; 2, the active filler layer of this device needs continuous spray washing liquid, consumes a large amount of recirculated water, and energy consumption is larger; 3, the cleaning solution of active filler layer is back to housing bottom, recycle as first order washing water source, the time has been grown later cleaning solution and can become strong acid, can corrode feeding spraying pump and shower nozzle on the one hand, can affect the acid-base value of active filler layer on the other hand, thereby affect the activity of biological inoculum.4, this device does not have Insulation, and in the situation that temperature is lower in the winter time, spray piping easily freezes on the one hand, and biological inoculum can't be survived at a lower temperature on the other hand.5, in fact, contained pollutant is various and complicated in the waste gas, use single treatment facility to be difficult to effectively remove simultaneously, special waste gas for some low threshold values, because the concentration of waste gas and intensity are not linear ratios, even exhaust gas concentration has reached national relevant discharge standard, but still can smell an offensive odor.This device is undesirable for the waste gas removal effect of some low threshold values.
The utility model content
In order to overcome defects, the purpose of this utility model provides the Ecology waste gas purification apparatus.
To achieve these goals, the utility model adopts following technical scheme:
The Ecology waste gas purification apparatus is made of Ecology filter bed, vegetation water wash mill and air exhauster, waste gas after blower fan is collected at first imports to the Ecology filter bed, after waste gas enters into the Ecology filter bed, distinctive fungi flora directly contacts with waste gas in the filter bed, the principle of simulating nature circle flora waste gas decomposition, utilize fungus degrading waste gas, waste gas is decomposed into CO
2, H
2O and other inorganic salts, thus waste gas is purified.Again import to the vegetation water wash mill through the waste gas after the purification of Ecology filter bed.This wash mill can effectively be removed the emission molecule of low threshold value, and then strengthens and guarantee the effect that the Ecology filter bed is processed, and makes the waste gas qualified discharge after the processing.
The Ecology filter bed is comprised of attemperating unit, housing, colony culture medium, buffering area, humidity control device etc.; The bottom of Ecology filter bed is buffering area, is provided with colony culture medium in the centre of filter bed, is provided with humidity control device above colony culture medium.
The vegetation water wash mill is comprised of housing, packing layer, gas pipe, water circulating pump and circulating water chennel; The bottom of wash mill is circulating water chennel, and the tank top is air inlet, is provided with packing layer in the centre of wash mill, is provided with the plant liquid spraying shower nozzle above packing layer; Deodorant liquid in the circulating water chennel is transported to the spray nozzle of packing layer top through water circulating pump, deodorant liquid is sprayed packing layer, deodorant liquid comes back to circulating water chennel after packing layer and waste gas fully react, circulating water chennel is provided with the pH value checkout gear, and precision metering pump adds deodorant liquid toward circulating water chennel automatically according to the data of pH value checkout gear.
The utility model structure possesses following characteristics:
A, this device adopt fungi as biological flora, utilize the pollutant of fungus degrading hydrophobicity or poorly water-soluble, and its degradation efficiency is higher than the degradation efficiency of bacterium.The pH value that fungi adapts to is 3～6, when processing acid waste gas or acid accumulation occurring, does not need to add alkali and adjusts the pH value.Particularly for some organic matter, the degradation capability of fungi is higher than bacterium.
B, fungi can grow in dry environment, need not continuous spraying and sprinkle water to keep moist environment, and this is just so that need not to consume a large amount of recirculated water, and energy consumption is lower.
The inlet end of the waste gas of C, this device is provided with attemperating unit, in the situation that temperature is lower in the winter time, can avoid shower to freeze on the one hand, can provide a suitable temperature to flora on the other hand.
D, this device adopt combined type waste gas purification technique, and strong shock resistance is even more ideal for low threshold value waste gas purification effect.
The cleaning solution that adopts in E, the vegetation water scrubbing tower is natural botanical extraction liquid, eighteenth of the twenty etc. in soft, the fluorine, and nontoxic, nonirritant, without flammability can not produce secondary pollution with the generation of waste gas reaction.
The waste gas purification principle that this device utilizes the washing of Ecology filter bed and vegetation water to combine, make emission molecule respectively biological flora fully contact with plant deodorization liquid, absorption and waste gas decomposition molecule, the end product of reaction is harmless molecule, such as water, oxygen, nitrogen.After this technology is succeeded in developing and put on market, be widely used in the deodorizing of sewage treatment plant, sewage pumping station, refuse landfill, garbage transfer station, plant location.
Description of drawings
Fig. 1 is the utility model structural representation.
Icon is: admission line 1, air exhauster 2, attemperating unit 3, humidity control device 4, colony culture medium 5, buffering area 6, housing 7, circulating water chennel 8, gas pipe 9, packing layer 10, spray nozzle 11, water circulating pump 12.
The specific embodiment
Further specify below in conjunction with accompanying drawing:
