Description

Photocatalysis organic waste-gas purification device
Technical field
The utility model relates to a kind of photocatalysis organic waste-gas purification device, belongs to the industrial organic waste-gas purification field.
Background technology
Atmosphere pollution is one of at present the most outstanding environmental problem of China; Industry photocatalysis waste gas is the important source of atmosphere pollution; The purpose of industry photocatalysis waste gas purification is in order to remove poisonous and harmful substance and the flue dust in the commercial production discharging waste gas; Make it handle the back qualified discharge, reduce pollution atmosphere.
Existing organic waste-gas purification device comprises the active carbon layer of being located in the cabinet, and this cabinet is provided with exhaust gas entrance and waste gas outlet, and organic exhaust gas gets into cabinet from exhaust gas entrance, through the filtration of active carbon layer, purifies the back and is discharged to the atmospheric environment from waste gas outlet.Yet active carbon layer is limited to the purification of organic exhaust gas, needs the frequent change active carbon, and operation cost is high.Often can not reach the effect of cleaning organic waste gas effectively.
Summary of the invention
The technical problem that the utility model will solve provides a kind of photocatalysis organic waste-gas purification device of more effectively purifying exhaust air.
The photocatalysis organic waste-gas purification device of the utility model comprises that one is provided with the cabinet of exhaust gas entrance and waste gas outlet, is provided with an active carbon layer between said exhaust gas entrance and the waste gas outlet, also is provided with a photocatalysis layer between said exhaust gas entrance and the active carbon layer.
One plasma generator also is set between said exhaust gas entrance and photocatalysis layer, and it is located in the distribution box.
On cabinet, also establish a new wind inlet, this new wind porch is provided with a filter; Waste gas outlet place at cabinet establishes a blower fan.
Filter is provided with an energetic ion generator away from a side of new wind inlet.
Purification through plasma generator, photocatalysis layer is transformed into organic compound nonhazardous inorganic molecules compounds such as carbon dioxide and water with heat, light, catalyst etc.Harmful substance obtains decomposing, purifying, and passes through the filtration of active carbon layer again, can remove harmful substance and microorganism free in the waste gas, produces more effective clean-up effect; And new wind porch can get into more energetic ion wind and fresh air, has diluted the organic exhaust gas that gets into exhaust gas entrance, can prevent the risk of blast.
Description of drawings
Fig. 1 is the schematic appearance of the utility model;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the side view of the utility model.
The specific embodiment
Combine accompanying drawing and embodiment that the utility model is done further explain at present.
Referring to Fig. 1, Fig. 2, the photocatalysis organic waste-gas purification device of the utility model comprises that one is provided with the cabinet 10 of exhaust gas entrance 11 and waste gas outlet 12, is provided with a photocatalysis layer 20 and an active carbon layer 30 between exhaust gas entrance 11 and the waste gas outlet 12 successively.
Photocatalysis layer 20 is provided with photocatalyst (Photocatalyst), and photocatalyst (Photocatalyst) also is photochemical catalyst (Lightcatalyst), be one type with titanium dioxide (TiO 2) for representative, under the irradiation of light, self do not change, but can promote chemical reaction, have the general name of the semi-conducting material of catalysis.TiO 2As a kind of photocatalyst; After the ultraviolet ray in absorbing sunshine or lighting source; Redox reaction takes place under the exciting of ultraviolet energy; The surface forms the hydroxyl free radical and the ultra-oxygen anion free radical of strong oxidizing property, resolves into harmless carbon dioxide and water to harmful substance and microorganism free in the air, thus reach purify air, purposes such as sterilization, deodorizing.
After the photocatalysis organic exhaust gas got in the cabinet 10, through the filtration of photocatalysis layer 20, harmful substance obtained decomposing, and passes through the filtration of active carbon layer 30 again, can more effectively remove harmful substance and microorganism free in the waste gas, is discharged in the atmosphere at last.
One plasma generator 40 also can be set between exhaust gas entrance 11 and photocatalysis layer 20; It is located in the distribution box; Plasma generator 40 can produce a large amount of plasmas, and plasma is a kind of state of aggregation material, it be different from the general knowledge " Gu ", " liquid ", " gas " ternary material; It is the 4th attitude of material; A series of primitive physical reactions can take place during with airborne molecular collision in the high energy electron that it had, and in course of reaction, produce various active free radical and ecological oxygen, and promptly ozone decomposes and the elemental oxygen that produces.Living radical can destroy the nucleic acid in various viruses, the bacterium effectively, and protein makes it can not carry out normal metabolism and biosynthesis, thereby causes its death; And ecological oxygen can decompose multiple macromolecule gas with foreign flavor or be reduced to low molecule innocuous substance rapidly; In addition, by the coalescence effect of ion in the plasma and object, can carry out effective collection to little fine particulates to submicron order.
When yet organic exhaust gas passes through charged plasma generator 40, exist the risk of blast.Can on cabinet, establish new wind inlet 13 for this reason, be provided with an energetic ion generator 50 near the new wind inlet 13, and export 12 places at cabinet and establish a blower fan 60; When blower fan 60 started, ozone can get in the cabinet 10 from new wind inlet 13, through energetic ion generator 50; Under electric field action, ion generator 50 produces a large amount of α particles, collides with airborne oxygen molecule and forms positive and negative oxonium ion; And join with the ion of plasma generator 40; Positive oxonium ion has very strong oxidisability, can oxidation in the extremely short time, decompose pollution factors such as methyl mercaptan, ammonia, hydrogen sulfide, and with the chemical bond of opening volatile organic compounds after the VOC molecule contacts; Through a series of reaction, finally generate carbon dioxide and water etc. and stablize harmless little molecule.Simultaneously, oxonium ion can destroy the living environment of bacterium in the air, reduces interior space bacterial concentration, and charged ion can adsorb the suspended particulate greater than tens times of own wts, settles down by deadweight, thereby removes suspension colloid; And the organic exhaust gas that gets into from exhaust gas entrance 11 has also been diluted in the adding of fresh air, makes organic exhaust gas further reduce through the risk that charged case produces blast.
Also be provided with a filter 70 between new wind inlet 13 and the energetic ion generator 50, so that air obtains preliminary purification.
The above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Though the utility model discloses as above with preferred embodiment; Yet be not in order to limiting the utility model, anyly be familiar with the professional and technical personnel, in the scope that does not break away from the utility model technical scheme; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be the content that does not break away from the utility model technical scheme, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
