Combined cooking fume gas purifying system

Abstract

The invention discloses a combined cooking fume gas purifying system, and belongs to the field of air purification. The combined cooking fume gas purifying system comprises a static electricity cooking fume purifier, and is formed by the combination of a plurality of modules; the purification modules arranged sequentially from the cooking fume inlet to the cooking fume outlet in the system include a fireproof deoiling baffle, a static electricity cooking fume purifier, a photocatalytic mechanical filter and a draught fan component. Three purification modules are adopted for the system aiming at the cooking fume in a kitchen; a unique combined purification mode is applied; cooking fume is separated efficiently; dual-filtration is carried out, and then smell is adsorbed, so that the cooking fume in the kitchen is purified maximally.

Description

technical field [0001] The invention relates to a gas purification system, in particular to a compound fume gas purification system, which belongs to the field of air purification. Background technique [0002] In recent years, with the development of urbanization and the adjustment of industrial structure, China's tertiary industry has developed rapidly, and the catering industry has developed particularly rapidly. Not only large and super large restaurants and restaurants often need dozens of sets of stoves, hundreds of sets of stoves, and cities Barbecue restaurants with kebabs, barbecue, and grilled chicken wings have gradually appeared in China. These restaurants use coke and charcoal as fuel, and will generate a large amount of oil fume and dust rich in PM10 and PM2.5 particles. These harmful Substances are the chief culprits of atmospheric smog. In order to reduce the pollution of the oily fume produced by the catering industry to the atmosphere, the industry is const...

Problems solved by technology

[0013] The beneficial effects of the present invention are: by using the fire-proof and oil-removing baffle in the system, and using mechanical separation principles such as filtration, collision, cooling, and adsorption, it solves the difficulty of self-flow due to the large proportion of oil fume in the application of filtration and adsorption control technology, and the large pressure drop Weaknesses; solve the problem of low capture efficiency, to achieve the effect of ventilation and separation; by using the electrostatic oil fume purifier in the system, using the ionization section and dust collection section in it, the oil fume gas molecules are ionized, and the oil mist particles are carried Charged, the charged particles move towards the grounding plate under the action of the electric field force, and the charged oil mist particles are adsorbed, captured on the dust collecting plate and carbonized to separate the oil mist
