Abstract
The utility model discloses an odorous gas processing device. The device comprises a reactor and a main air pipe, wherein, the main air pipe is filled with the odorous gas to be processed; a branch air pipe connected with the reactor is arranged on the main air pipe; the reactor comprises a housing, a blower and a plurality of ultra-violet lamps; the blower and the ultra-violet lamps are mounted in the housing; and a catalyst film is coated on the inner surface of the housing. The utility model has the advantages that the reactor is arranged at the external of the main air pipe so as to prevent odor pollutant, especially oil fume from adhering on the surface of a lamp tube effectively, thereby reducing cleaning frequency; the blower is arranged in the reactor so as to prevent ozonic air from flowing back when wind pressure in the main air pipe is over-high; and the branch air pipe extends into the main air pipe, so that negative pressure is formed in a local scope, thereby providing convenience for ozone to be scattered in the odorous gas in the main air pipe, and saving power.
Description
Technical field
The utility model relates to a kind of foul gas treating apparatus.
Background technology
The oil flue waste gas in restaurant and kitchen, hotel generally adopts static oil removing or water spray to handle, and directly is discharged to outdoor after the processing.Above method has removal effect preferably to volatility oil, cigarette and steam, but not good to the removal effect of the organic pollution of generation after other peculiar smell in the kitchen and the edible oil heating.These pollutants may jeopardize peripheral resident's health, and in addition, peculiar smell also influences people's work and life.The foul gas that produces in the sewage disposal process has had a strong impact on people's health, and this type of foul gas mainly contains hydrogen sulfide, ammonia, methyl mercaptan and volatile organic contaminant, and they are the reasons that cause stench.Oxidizing process is to handle the prefered method of this type of foul gas at present.
Ozone oxidation is a kind of method for gas purification of high-efficiency cleaning, but ozone reaction speed when some organic pollutions of oxidation is slow, and the reaction time is long; In addition, ozone generator is to the air humidity sensitivity, under the wet weather condition, and ozone generating capacity deficiency.
Photochemical catalytic oxidation also is usually used in the processing of indoor foul smell, produces the free-radical oxidation pollutant by the UV-irradiation catalyst.But because the photochemical catalytic oxidation energy utilization efficiency is low, the number of free radicals quantity not sufficient of generation, treatment effect is undesirable.
Summary of the invention
The purpose of this utility model is to solve the problems of the prior art, and a kind of foul gas treating apparatus is provided.
The technical solution of the utility model is: the foul gas treating apparatus, comprise reactor and air main, and be full of pending foul gas in this air main; Described air main is provided with a branch road airduct, and this branch road airduct and reactor join, and described reactor is made of housing, blower fan and a plurality of uviol lamp, and blower fan and a plurality of uviol lamp are contained in the housing, and the inner surface of described housing is covered with catalyst film.
Described branch road airduct extends in the air main.
Described blower fan is arranged on the import or export place of reactor shell.
Described catalyst film is one or both in titanium dioxide film or the manganese dioxide film.
Preferably, described uviol lamp is a vacuum UV lamp.
The beneficial effects of the utility model are: reactor is arranged on the air main outside, can prevent effectively that odor pollution thing, particularly oil smoke from sticking to surface of the light tube, has reduced cleaning frequency; Be provided with blower fan in the reactor, ozone-air flows backwards when preventing that the air main blast is too high; The branch road airduct extends in the air main, and it forms certain negative pressure in subrange, helps ozone and is dispersed in the interior foul gas of air main, saves power.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the foul gas treating apparatus comprises reactor and air main 5, is full of pending foul gas in this air main 5; Described air main 5 is provided with a branch road airduct 4, and this branch road airduct 4 joins with reactor, and described reactor is made of housing 3, blower fan 1 and a plurality of uviol lamp 2, and blower fan 1 and a plurality of uviol lamp 2 are contained in the housing 3, and the inner surface of described housing 3 is covered with catalyst film.
Described branch road airduct 4 extends in the air main 5.
Described blower fan 1 is arranged on the import or export place of reactor shell 3.
Described catalyst film is one or both in titanium dioxide film or the manganese dioxide film.
Preferably, described uviol lamp 2 is a vacuum UV lamp.
In the reactor shell 3 of the present utility model blower fan 1 is set, is used to prevent that the stench odour in the air main 5 from flowing backwards away from branch road airduct 4; Reactor shell 3 inner surfaces are covered with one or both the catalyst film in titanium dioxide or the manganese dioxide, and be used for catalysis ozone and UVC ultraviolet light and produce hydroxyl radical free radical, but the pollutant in the hydroxyl radical free radical efficient oxidation foul gas.
Using method of the present utility model: open uviol lamp 2 and blower fan 1, blower fan 1 is with in the air suction reactor shell 3, the air of suction produces ozone under the irradiation of uviol lamp 2, ozone generates hydroxyl radical free radical under the effect of reactor shell 3 inner catalysts, under blower fan 1 action of centrifugal force, enter the pollutant in the air main 5 oxidation Decomposition foul gas, finally obtain pure air.
Being embodiment of the present utility model only in sum, is not to be used for limiting this novel practical range, and promptly all equivalences of doing according to the content of the utility model claim change and modify, and all should belong to technology category of the present utility model.
