Abstract
The invention relates to deodorization technologies in environmental sanitation, environmental protection facilities, agricultural and sideline product processing industry and chemical industry production fields. As one of seven typical public hazards, fetor involves various materials, has a large range of influence, and seriously impairs human health. The invention provides a biochemistry-physicochemistry combined deodorization device, which is composed of a deodorization device main body, an air distribution pipe, a valve and other components. The deodorization device main body is internally divided into three layers. The bottom layer is a microbial decomposition layer, the second layer is a physical adsorption layer, and the third layer is a photocatalytic decomposition layer. The odor treated by the biochemistry-physicochemistry combined deodorization device can realize harmlessness, and meets the relevant provisions of national emission standards.
Description
Affiliated technical field:
The present invention relates to the removal stink invention technology of environmental sanitation, environmental protection facility, farm and sideline product processing industry and chemical production field.
Background technology
Stench is as one of 7 kinds of typical public hazards (atmosphere pollution, water pollution, stench, soil pollution, noise, vibration, land subsidence), its substance classes is various, coverage is big, and serious harm health, cause the generally attention of countries in the world, the research of relevant deodorization technology has become an important link in the environmental improvement engineering.
At present, the removal method for stink mainly contains: (1) chemical deodorizing method (oxidizing process, absorption process, absorption method) comprises firing method (flame combustion, catalytic combustion); (2) physical deodorization method, as cover the method for keeping away, dilution diffusion method etc.; (3) biological deodorizing method mainly is to utilize microbial deodorant, and the material that the physiological metabolism by microorganism will have stink is transformed.(4) physical chemistry deodorization process, perhaps be the light-catalyzed reaction technology: belong to the physical chemistry category on the photocatalysis chemistry origin, belong to catalytic chemistry in essence, photoelectricity be " driving force " of chemical reaction be again the catalyst of chemical reaction; The photoelectrocatalysis agent is again power.
The conventional control technology of above stench respectively has its benefit and limitation.A physics method suitable treatment low concentration, the stench that scope is little, and cost is higher; The chemical method deodorizing is not lasting, deodorizing facility investment and operating cost height; Though bioanalysis is with low cost, effective, the screening and culturing of bacterial classification is difficulty comparatively, takes effect slightly slow and can't move cold season.Etc..
Summary of the invention
The invention provides a kind of biochemistry-materialization combined type deodorization arrangement, namely can bring into play the superiority of various deodorizing methods effectively, can adapt to various meteorological conditions and various operating condition again, reach the purpose of energy-efficient thorough removal stink.
Biochemistry-materialization combined type deodorization arrangement is made up of parts such as deodorizing equipment body, wind-distributing pipe, valves.Divide three layers of design up and down in the odor removal main body, bottom is the microorganism decomposition layer, and the second layer is the physical absorption layer, and the 3rd layer is the photocatalysis Decomposition layer.Preliminary purification gas drained into the second layer after odorous gas contacted with biofilter material and filters, after little spray painting pouring purification and the absorption of how empty filtrate, enter the photocatalysis Decomposition layer again, the photocatalysis section guarantees that whole foul smell evenly contact fast with ion-oxygen and the rapid mixing of air.Photocatalysis apparatus is accelerated the reaction speed of gas and ion-oxygen.A large amount of cluster ions that the ion-oxygen generator produces have high activity, after the foul smell molecule contacts, open its chemical chain, and the foul smell molecular oxygen is changed into simple harmless compound, and purified gas can reach emission request and directly discharge.
Said biofilter material is filler with the mixture of corrosion resistant string thing or porous materials or corrosion resistant string thing and porous materials, and inoculation has microorganisms such as saccharomycete, bacterium and actinomyces in filler.
The physical absorption layer is filled conventional active micropore filtrate, such as: volcanic rock, shell, float stone, activated carbon etc.
The configuration wavelength is the special source tube bank superpower ultraviolet ray of generation and the high-concentrated ozone of 184.9nm and 253.7nm in the photocatalysis Decomposition layer, realizes the oxidation Decomposition to gas with foreign flavor, and big of its accessory substance is carbon dioxide and water.
Description of drawings
Figure of description is structure chart of the present invention:
1 is the odor removal body among the figure, and 2 is the photocatalysis Decomposition layer, and 3 is wind-distributing pipe, and 4 is valve, and Fig. 5 is blast pipe,
Fig. 6 is biological filter material layer, and Fig. 7 is the physical absorption filter material layer, and Fig. 8 is exhaust duct.
The specific embodiment
As shown in the figure: system's pressure fan is delivered to blast pipe 5 with odorous gas, and odorous gas passes through biofilter material layer 6 and photocatalysis Decomposition layer 7 successively, finishes biochemistry-materialization deodorisation process, through exhaust duct 8, drains into atmosphere.
When meteorological condition and the bigger variation of processed gas flow generation, but appropriate regulation valve 4 enters the photocatalysis Decomposition layer to realize processed odorous gas short circuit, finishes the process of taking out stink.
