Water mist membrane filter cloth and membrane covering method thereof

The invention provides water mist membrane filter cloth which comprises a bag-shaped filter bag, and water mist membranes are coated on the inner side surface and in pores of the filter bag. The water mist film is composed of water mist. The water mist is periodically coated on the inner side surface of the filter bag and in pores. The invention provides a film covering method for water mist film filter cloth. The film covering method comprises the following steps: step 1, introducing water mist generated by an ultrasonic atomizer into a reverse blowing fan; step 2, spraying the water mist and air into an expandable air bag by the reverse blower, and spraying the air mixed with the water mist into the filter bag by the air bag through a linear valve which can be intermittently opened. The problem that the air permeability of the filter material is poor due to the fact that the film covering mode of the filter material such as a cloth bag is not appropriate at present is effectively solved. 本发明提供一种水雾膜滤布，包括袋状的滤
