A range hood micro-discharge plasma removal system for exhaust gas

Abstract

The invention relates to the field of range hoods, and discloses a microdischarge plasma exhaust gas removal system of a range hood. The microdischarge plasma exhaust gas removal system comprises a machine box, an air exhaust chamber, an outer connector and an air inlet end. A ventilation chamber is arranged on the inner side of the machine box in a penetrating manner. Medium stop plates the samein height are fixedly paved on the two sides of the outer surface of the inner side of the machine box. A longitudinal polar plate is arranged on the outer surfaces of the inner sides of the medium stop plates in the vertical direction. Transverse polar plates are fixedly arranged at the positions, close to the lower end of the longitudinal polar plate, of the outer surfaces of the inner sides ofthe medium stop plates. A plasma power supply device is fixedly arranged on the outer surface of the machine box. A smoke sensor is arranged at the position, close to the lower end of the outer surface of the inner side of the machine box. According to the microdischarge plasma exhaust gas removal system of the range hood, smoke is ionized through a high-voltage electric field, dust charge is separated from gas flow under the action of the electric field, the aim of purifying exhaust gas of the range hood is achieved, and the advantages of purifying air, reducing pollution to air and achievingenergy saving and emission reduction are achieved.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a system for removing waste gas by micro-discharge plasma for range hoods. Background technique [0002] In recent years, smog, mainly composed of inhalable fine particles (PM1.0, PM2.5, PM10), volatile organic compounds (VOCs), moisture and harmful microorganisms, is a major problem that continues to plague and seriously affects people's health. Environmental problems, cooking fume is produced by heating food oil and food at high temperature. The high-temperature oil fume condensate has strong carcinogenic and mutagenic hazards. Since most restaurants and restaurants are located in downtown and residential areas, the cooking fume is emitted to surrounding residents. The problem of oil fume pollution from the catering industry and the nuisance to the people has become one of the hot issues of urban residents' environmental protection complaints. [0003] Micro-discharge plasma is a sp...
