Problems solved by technology

[0006] In the past, people tried to use water washing, activated carbon filtration, adsorption and other methods to purify odors, but the effect was not only poor but also caused secondary pollution
Some people use the method of biological deodorant biological liquid to atomize and spray the deodorizing working liquid in the space near the kitchen, so that the deodorizing working liquid droplets can absorb the odor substance molecules in the oil fume, and the adsorbed odor substance molecules can be combined with the deodorizing substance molecules. The working fluid reacts, and as a result, not only the effect of removing odor is not good, but also the cost is high and there is secondary pollution

Embodiment 1

[0033] figure 1 and figure 2 All are structural schematic diagrams of different angles of a preferred embodiment of the photochemical cooking fume deodorizer 17 described in the present invention. The inlet 7 and the oil fume outlet 11 are provided with a uniform air guide device 5 on the inner wall of the housing 6 on the side of the oil fume inlet 7. In the cavity, a number of ultraviolet light sources are respectively used to support the solid storage device 8 and the photocatalyst catalytic device fixing part 4. The ultraviolet light source device 2 and the photocatalyst catalytic device 3 of net shape. Wherein, the photocatalyst catalytic device 3 is arranged in a direction perpendicular to the oil fume flow direction. The ultraviolet light source device 2 is composed of ultraviolet lamp tubes with a wavelength of 100-200nm and electronic ballasts. The ultraviolet lamp tubes are arranged in columns in the base plane perpendicular to the oil fume direction; the device i...

Embodiment 2

[0037] image 3 The structural representation of the preferred photochemical catering oil fume deodorizer used in a photochemical catering oil fume deodorization system of the present invention, by image 3 It can be seen that the photochemical catering oil fume deodorization system consists of a smoke exhaust hood 12, an elbow pipe 13, a square-to-round pipe 14, an electrostatic degreasing device 15, a variable diameter pipe 16, and the photochemical catering oil fume deodorizer 17 of the present invention. , Connecting pipe 18, fan 19 and air outlet pipe 20 form.

[0038] When in use, cooking oil fume (comprising cooking oil fumes and stove burner waste gas) is inhaled through the smoke exhaust hood 12 under forced ventilation, enters the elbow, square to round pipe, electrostatic degreasing device 15, and passes through the electrostatic degreasing device 15. After the preliminary pretreatment, it enters the photochemical catering oil fume deodorizer 17 through the variabl...

Abstract

The invention relates to a photochemical catering oil smoke smell removing method and a photochemical catering oil smoke smell remover, belonging to the technical field of protection of atmosphere and inhabited environments of urban and rural residents. The smell removing method is realized by irradiating the oil smoke by ultraviolet ray and catalyzing the oil smoke by photocatalyst. The smell remover comprises a shell, a cavity formed by the shell as well as an oil smoke inlet and an oil smoke outlet of the cavity, wherein the cavity is also internally provided with a plurality of ultraviolet ray source devices and photocatalyst catalyzing devices. The invention combines ultraviolet ray, ozone and photocatalyst and associates the ozone and a plurality of active free radical strong oxidizers, and the cooperative interaction thereof has a multiplied integrative catalyzing effect so as to greatly quicken the speed of photolysis and oxidation reaction, shorten the purifying working course of photolysis and oxidation to less than 0.1 second and greatly improve the efficiency for purifying and processing poisonous substances and substances with peculiar smell for the catering oil smoke.

Description

【Technical field】 [0001] The invention relates to a method for purifying fumes, toxic substances and peculiar smells in catering and food processing industries, as well as equipment and systems used therein, and belongs to the technical field of protection of the atmosphere and the living environment of urban and rural residents. 【Background technique】 [0002] Since the reform and opening up 30 years ago, the urban and rural catering and food processing industries have achieved great development, and people's living standards have been greatly improved. However, during the cooking process, a lot of oily smoke and peculiar smell are produced, and the peculiar smell spreads to the surroundings, which is pungent and unpleasant, and seriously pollutes the atmosphere. and the living environment of urban and rural people. [0003] Generally speaking, the flue gas of the catering industry is composed of two parts of mixed pollutants, the exhaust gas of the stove and the cooking fu...
