Low-noise cooking fume purification fan

Abstract

The invention provides a low-noise cooking fume purification fan, and belongs to the technical field of waste gas treatment machines. The low-noise cooking fume purification fan solves the problems that an existing purification fan is low in purification efficiency and high in noise. The low-noise cooking fume purification fan comprises a box body, a panel and a base. The panel is mounted on the box body to form a fan shell. The base is fixedly connected to the bottom of the box body to achieve a supporting function. The interior of the box body can be sequentially divided into a fan segment,a purification segment and a noise reduction segment. A motor, an impeller and a fan cover are mounted at the position, located on the fan segment, in the box body. The impeller is mounted on a motortransmission shaft and is connected with the fan cover to form an air inlet. The purification segment is arranged at the position, located behind the motor, in the box body. A filter, photocatalyst carrier nets and ultraviolet lamps are sequentially mounted on the purification segment. The the two layers of photocatalyst carrier nets are arranged, and the ultraviolet lamps are located between thetwo photocatalyst carrier nets. The noise reduction segment is arranged at the rear end of the box body, noise reduction cotton is arranged on the panel in an attached manner, multiple noise reductionbarrels are exhibited in the box body, and therefore the effect of noise reduction is achieved. The low-noise cooking fume purification fan has the advantages of being low in noise and high in purification efficiency.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment machinery, and relates to a fan, in particular to a low-noise soot purifying fan. Background technique [0002] Oil fume purification is a kind of equipment specially formulated for oily and smelly equipment. It can make the oil fume discharge tasteless, pollution-free, safe and fire-resistant. It is mainly used for the purification and treatment of low-altitude kitchen fumes; , restaurants, schools, institutions, factories and other places; food frying and cooking processing industries; industrial occasions such as oil splash heat treatment workshop, oil mist lubrication workshop, workpiece welding workshop and olefin oil boiler discharge, by changing the filter element, it can also be used Purify in laboratories, operating rooms, smoking rooms and other related places. The kitchen fume exhaust gas treatment device is the fume purifier. The national standard for cooking fume purifica...

AI Technical Summary

Problems solved by technology

[0004] At present, the filtering effect of conventional oil fume purification fans on the market is generally only achieved through physical filtration. After absorbing the exhaust gas, it will absorb the pollutant particles contained in the fiber filter material. The purification efficiency is generally 80~90%. If it reaches a higher efficiency Then the resistance increases a lot, reaching more than 1000Pa, the replacement cycle of the filter element is also greatly shortened, and it produces a lot of noise
