Photolysis oxidation oil fume purifier

Abstract

The present invention discloses a photolysis oxidation oil fume purifier, which comprises a purifier main body, an oil stain filtration system, a photolysis oxidation system, a ventilation pipeline system, and a control system, wherein the purifier main body comprises a purifier housing, a maintenance observation door arranged on the front surface of the purifier housing, and a stain collection port arranged between the lower portion of the purifier housing and a stain separation plate, the oil stain filtration system comprises a tapered diversion body arranged at the inlet of the purifier, a diversion sheet, and the stain separation plate, and the photolysis oxidation system comprises a high energy ultraviolet ray lamp arranged on the inner side of the tapered diversion body, a lamp tube installation frame, and a titania coating coated inside the tapered diversion body and the purifier housing and on the stain separation plate and the lamp tube installation frame. The photolysis oxidation oil fume purifier of the present invention has characteristics of grease decomposition, smoke odor removing, excellent smoke removing pipeline disinfection effect, and easy use and maintenance.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to a photolytic oxidation oil fume purifier that can meet the oil fume emission standards of the catering industry. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, my country's catering industry has developed rapidly. However, the emission of cooking fume in the catering industry has not been effectively controlled. A large amount of untreated cooking fume is discharged outside in an orderly manner through range hoods or exhaust fans. In the atmospheric environment, it has caused great harm to the surrounding environment, thereby endangering our lives and health; and because smoke, dust and other substances adhere to the range hood and exhaust fan, it is extremely difficult to clean and it is easy to cause fire hazards. For this reason, the State Environmental Protection Administration promu...

AI Technical Summary

Problems solved by technology

However, the current photolytic oxidation oil fume purifier still has the following deficiencies: 1. Because there are many oil fumes in Chinese food, if the oil particles in the oil fume purifier are too large and there are too many water vapor molecules in the oil fume, it will cause the problem of blocking ultraviolet rays. Transmission, resulting in the UV-C ultraviolet C-band (254-257nm) light emitted by the ultraviolet lamp can only cut off the surface of large particles of oil or the oil molecular chains that are effectively irradiated, resulting in the failure of some oil particles to be effectively removed

As a result of increased wind resistance, it is necessary to increase the wind pressure of the exhaust fan and increase energy loss

At the same time, the "grease physical filter" still has the problems of difficulty in daily maintenance and cleaning

2. The ultraviolet light tube is installed around the shell of the oil fume purifier. The ultraviolet light may be transmitted through the interface of the smoke pipe. The leakage of ultraviolet light and refracted light will affect the health of the operator

At the same time, the light from the shell of the oil fume purifier fails to effectively react with the grease

3. Failure to intuitively understand the dust and oil on the surface of the ultraviolet lamp tube, failure to clean up in time, will hinder the penetration of ultraviolet rays, affect the penetration rate of ultraviolet rays and the intensity of irradiation
