Oil mist removing method with automatic cleaning and device thereof

Abstract

The invention relates to an oil and smoke removing method and device with automatic cleaning function. The method is that: adopt a rotating structure to drive a filtering rotaing barrel made of filtering material to rotate and make the filtering material cycle through an air process zone, a liquid cleaning zone and an air back flushing zone in sequence; on the air process zone, the filtering material filters the oil and smoke in the air, the air after processed can be discharged out directly; on the liquid cleaning zone, adopting cleaning agent and spaying device to force the oil and smoke separated from the filtering material; on air back flushing zone, using high pressure air to blow away the cleaning agent remained on the filtering material. The device mainly comprises: a shell, a blower, filtering material and a rotating structure, the rotating structure comprises a wheel carrier, a filtering rotating barrel and a motor, the motor drives the filtering rotating barrel to rotate, the filtering material can rotate in the air process zone, the liquid cleaning zone and the air back flushing zone according to the pre-set speed. The device can work continuously and be under the situation of high efficiency and low flow resistance for a long time, which doesn't need manual regular cleaning and saves time and labour.

Description

technical field [0001] The invention relates to a waste gas treatment method and a device thereof, in particular to a degreasing mist method with automatic cleaning and a device thereof. Background technique [0002] People often encounter some oil mists in daily life, such as the paint mist produced by the spray painting process; the catering industry: the tiny oil mist generated during the heating process of edible oil; the solid tiny particles generated by the Millard reaction in the food processing process, These oil mists not only cause great harm to the human body, but also pollute the living environment. Usually, most of the organic solvents in the paint exhaust gas and the organic substances in the catering exhaust gas can be recovered or decomposed by the organic exhaust gas treatment device, but the paint mist and oil mist contained in it will cause the organic exhaust gas treatment device to block. Separation of paint mist and oil mist from catering exhaust gas i...

Problems solved by technology

At present, the filtration method is generally used to separate paint mist or oil mist. The filtration method is to use lipophilic polymer composite materials such as activated carbon, non-woven fabrics, sponge or spherical filter materials, etc. The oil mist and particulate pollutants in the air are intercepted. This purification method has the advantages of high purification efficiency, but with the increase of operating time, the filter material is easy to clog and the pressure of the filter device increases. It is necessary to replace or clean the filter material regularly, which is troublesome to maintain. , high operating costs, large fan power, easy to generate noise and other pollution
