[0002] The main state of oil fume emissions is aerosol fine particles; from the perspective of particle size characteristics, the PM1 / PM2.5 mass ratio is 0.66-0.85, indicating that the cooking process in the catering industry mainly emits aggregated particles with a particle size of <1μm. This type of organic aerosol particles are fully mixed with the atmosphere and exist for a long time, which can affect the atmospheric environment. The PM2.5 / PM10 range is 0.57-0.62, indicating that cooking also produces about 40% of coarse oil fume particles.

[0021] The interior of the shell 1 is provided with three sections of guide rails 9 distributed in the length direction, and the three sections of the guide rails 9 are sequentially placed with a honeycomb oil removal filter 4, a composite material plate electrostatic field 5 and a non-woven activated carbon filter assembly 6.

Corresponding indicator lights 10 are placed on the cabinet doors 72 for observing the real-time status of the device.

[0022] The honeycomb oil removal filter 4 uses multiple herringbone aluminum foils, which are nested with each other and symmetrically distributed. The thickness of the honeycomb oil removal filter 4 is 50 mm. The width and length of the honeycomb oil removal filter 44 vary with the model of the purification equipment and are on the inner side of the air inlet 2.

When an electrostatic electric field is formed between the composite plate of the source and the grounded composite plate, the charged oil fume particles move toward the composite plate under the action of the electric field force. After reaching the plate, the oil fume particles release the electrons they carry, and the oil fume particles are deposited on the plate, and the purified gas is discharged out of the dust collecting area 52; the purified oil fume exhaust gas passes through the dust collecting area 52 and enters the non-woven activated carbon filter assembly 6. After the non-woven activated carbon filter body 62 absorbs most of the odor in the oil fume exhaust gas, the purified gas is discharged through the air outlet 3 to achieve the purification purpose.
