Fume purification device and central fume purification equipment

Abstract

The invention provides a fume purification device and central fume purification equipment, and relates to the technical field of purification equipment. The fume purification device comprises a ventilation pipe, an active carbon carrier layer is arranged in the ventilation pipe, the shape of the active carbon carrier layer is matched with the cross section shape of the ventilation pipe, and a photocatalyst corresponding to the ultraviolet rays is loaded on the active carbon carrier layer; an ultraviolet lamp is arranged in the ventilation pipe, and the ultraviolet lamp corresponds to the active carbon carrier layer; the central fume purification equipment comprises a public gas flue, an exhaust fan and the fume purification device; and the gas outlet end of the public gas flue is communicated with a gas inlet of the ventilation pipe, and a plurality of fume collecting hoods are communicated with the public gas flue. The fume purification device has good purification effect on VOCs element in the fume gas, the content of the VOCs element in the gas which is exhausted out of the ventilation pipe is greatly decreased, and pollution to the environment by the exhausted gas is reduced.

Description

technical field [0001] The invention relates to the technical field of purification equipment, in particular to an oil fume purification device and central oil fume purification equipment. Background technique [0002] The production process of traditional Chinese food culture includes frying, frying, deep-frying, roasting, etc. During the process of making food, a lot of oil fume is produced. Kitchen oil fume is made of animal and vegetable oils under high temperature heating, through thermal oxidation and pyrolysis and Millard A large amount of volatile substances are produced by reaction and other ways, that is, VOCs (volatile organic compounds) volatile organic compounds, VOCs are aerosol particles, which have the characteristics of fine particle size, strong adhesion and hydrophobicity. [0003] Existing oil fume purification devices are generally equipped with ultraviolet lamps and photocatalysts. The ultraviolet lamps irradiate ultraviolet rays outward, and VOCs are d...

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of oil fume purification device and central oil fume purification equipment to solve the problem that the oil fume purification device in the prior art cannot efficiently purify the VOCs in the oil fume, and the discharged gas still contains a relatively high content of VOCs components. There are still technical problems of pollution to the environment
