Rare earth catalytic low temperature plasma kitchen fume purification method and device

Abstract

The invention discloses a rare earth catalyzed low-temperature plasma kitchen fume purification method and device. A small part of the kitchen fume enters the plasma generation area after being dried, and the plasma generated by the atomization discharge enters the adsorption-catalysis synergistic plasma purification area, and most of the kitchen oil fume directly enters the adsorption-catalysis synergistic plasma purification area, and is purified after full contact with the plasma. The purified oil fume is exhausted from the oil fume outlet to the outside. The device includes a plate-hole-plate corona atomization discharge plasma generation area, an adsorption catalysis synergistic plasma purification area, and a shell; the shell is provided with an upper oil fume inlet, a lower oil fume inlet, and an oil fume outlet. The invention relies on rare earth catalysis to cooperate with low-temperature plasma to purify kitchen oil fume. The oil fume removal rate is as high as 99.5%, and the odor removal rate is as high as 80%. Both the discharge electrode plate and the adsorption filler are not easily polluted and corroded, which ensures the durability of the performance of the device.

Description

Technical field [0001] The present invention involves a low -temperature plasma technology catalyzed by rare earth, as well as the various harmful gases in the kitchen oil fume, efficiently eliminating odor and sterilization of oil fume purification device. Background technique [0002] With the continuous development of my country's economy, the tertiary industry has flourished, and the catering industry has developed rapidly, which has also triggered environmental problems.At present, most of the large amount of oil fume exhaust gas generated during the cooking process is directly discharged from the hood and exhaust fan to the outdoor. Oil fog, smoke, dust and other substances are adhered to the range hood and exhaust fan, making it extremely difficult to clean.More importantly, a variety of harmful substances in the oil fume discharged into the atmosphere without treatment, destroying the atmospheric quality.At present, dietary oil pollution has been listed as one of the thre...

AI Technical Summary

Problems solved by technology

[0003] Existing oil fume purification equipment is mainly divided into electrostatic deposition equipment, filtration equipment, and inertial separation equipment. Secondary pollution, difficult maintenance, etc.

There is a lack of oil fume purification equipment that can efficiently remove fine oil droplets and gaseous pollutants, overcome the viscosity of oil droplets, operate stably for a long time, remove peculiar smells, cause no secondary pollution, and be easy to maintain
