Method for purifying cooking oil fumes through rare earth catalysis low-temperature plasma technology, and apparatus thereof

Abstract

The invention discloses a method for purifying cooking oil fumes through a rare earth catalysis low-temperature plasma technology, and an apparatus thereof. Few cooking oil fumes are dried, the dried cooking oil fumes enter a plasma after generation zone, plasmas generated through atomization discharge enter an adsorption catalysis cooperated plasma purification zone, most cooking oil fumes directly enter the adsorption catalysis cooperated plasma purification zone, fully contact with the plasmas and are purified, and purified oil fumes are discharged to the outside from an oil fume outlet. The apparatus comprises a plate-hole-plate corona atomization discharge plasma generation zone, the adsorption catalysis cooperated plasma purification zone and a shell; and the shell is provided with an upper oil fume inlet, a lower oil fume inlet and the oil fume outlet. The method and the apparatus purify the cooking oil fumes depended on the rare earth catalysis cooperated low temperature plasmas, the highest oil fume removal rate reaches 99.5%, the peculiar smell removal rate reaches 80%, and the concentration of each of pollutants after treatment meets requirements of Discharge Standard of Cooking Fume. A discharge electrode plate and an adsorption filler are not polluted or corroded, so the durability of the performances of the apparatus is guaranteed.

Description

technical field [0001] The invention relates to a low-temperature plasma technology catalyzed by rare earth, and an oil fume purification device for degrading various harmful gases in kitchen oil fume, effectively eliminating peculiar smell and sterilizing. Background technique [0002] With the continuous development of our country's economy, the tertiary industry is booming, and the catering industry is also developing rapidly, which has also caused environmental problems. At present, most of the large amount of oil fume and exhaust gas generated during the cooking process is directly discharged outdoors through range hoods and exhaust fans. Oil mist, smoke and other substances adhere to the range hood and exhaust fans, making cleaning extremely difficult. More importantly, a variety of harmful substances in the oil fume are discharged into the atmosphere without treatment, which destroys the air quality condition. At present, cooking fume pollution has been listed as one...

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
