Problems solved by technology

[0015] The latest photolytic oxidation oil fume purification technology that appeared on the market is still in concept, and there are not many applications of this technology in the market, mainly because its purification effect is not ideal
As we all know, ultraviolet technology is widely used in hospitals and related industries, and its deodorization and sterilization effects are very good, but ultraviolet light itself does not have the function of purifying oil fume.

Abstract

The invention discloses a cooking fume purification device and a working method thereof. The cooking fume purification device comprises a gas inlet hopper, an electrostatic purification chamber, a catalytic absorption chamber, an exhaust device and a control system, wherein the control system sends out a signal to control an exhaust fan of the exhaust device to start, cooking fume waste gas is sucked into the electrostatic purification chamber through the gas inlet hopper and enters the catalytic absorption chamber after being subjected to electrostatic precipitation by the aid of the electrostatic purification chamber, CO and peculiar smells in the waste gas are transformed and absorbed in the catalytic absorption chamber, and finally treated clean gas is exhausted from the exhaust device. The cooking fume purification device and the working method thereof are good in cooking fume purification effect, high in efficiency, capable of treating various toxic and harmful substances in cooking fume and widely applicable to various catering industries.

Description

technical field [0001] The invention belongs to the field of oil fume exhaust gas purification devices, and in particular relates to an oil fume purification device and a working method thereof. Background technique [0002] Although the development time of oil fume purification technology in China is relatively short, after more than 20 years of development, commonly used oil fume purification equipment on the market can be roughly divided into the following categories according to their working principles: [0003] 1. Mechanical [0004] Common mechanical types include centrifugal type (cyclone dust removal), filter type, clapboard type, etc. Mechanical treatment technology is mainly used in large-scale industrial dust removal, and is the mainstream treatment method in industrial dust removal. [0005] The cyclone dust collector is a dust removal device that uses the centrifugal force generated by the rotating air flow to separate dust particles from the combined dust ai...
