Full-automatic roll-to-roll air purification device and electret method

Abstract

The invention belongs to the technical field of environmental protection, and particularly discloses a full-automatic roll-to-roll air purification device and an electret method. The device comprisesa recycling reel, a storage reel, an electrode bracket, an corona electrode, an electric control box, an electric control plate, a filter net, a cellular board electrode, a stepping motor, a cross beam, a recycling box, a storage box and the like. According to the full-automatic roll-to-roll air purification device disclosed by the invention, an electrostatic electret device and a reel type electret filter net are mounted in an air filter unit; when the electrostatic effect of the filter net is reduced a little, the filter net is subjected to electrostatic electret treatment to recover the electrostatic effect of the filter net, and germs and viruses are killed; the number of filter nets stored on the reel is large enough for use for more than one year; and when the dust accumulation of anunfolded filter net reaches a set value, the old filter net is automatically recycled, and a new filter net is unfolded at the same time, namely the filter nets are automatically replaced, and are subjected to the electret treatment. The full-automatic roll-to-roll air purification device disclosed by the invention solves the problem that the electrostatic electret effect of the electret filter net of the conventional air purification device works for a short time, and realizes automatic replacement of the filter nets, thus avoiding manual operation of filter net replacement.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to a fully automatic roll-to-roll air purification device and an electret method. Background technique [0002] Electret filters are widely used in the field of air purification, such as masks, air filter elements, etc. The electret filters processed by the new electret can efficiently filter out dust in the air, and have a larger dust holding capacity compared with HEPA filters. , The wind resistance is smaller and the cost is lower. The electrostatic electret filter has excellent PM2.5 adsorption capacity and low cost. It is an ideal material for air filtration. However, the electrostatic electret effect is poor in timeliness, will fail in a short time, and does not have a sterilization function. [0003] The electret filter is not purely physical filtration, but absorbs dust through the static electrostatic field effect. Its efficiency mainly depends on the ...

Problems solved by technology

[0004] At present, the air filters are designed to be blocky and need to be replaced manually, which is easy to be ignored and the air filtration effect is greatly reduced. Moreover, the bacteria and viruses accumulated on the filter will cause secondary pollution. Therefore, the function of automatic filter replacement is also very important. necessary
