Description

Air washing filter structure

This creation relates to a wet screen, and in particular to an air wash screen structure.

In the prior art, the method of purifying air generally uses a paper filter or a chemical filter to remove dust, particles, gas glue, chemical molecules and the like in the air, and the pollutants pass through a paper filter or a chemical filter. The dense mesh structure (paper filter) through the filters or the high intermolecular affinity (chemical filter) between the materials and the pollutants causes the pollutants to adhere to the filter screen. Since the above method does not use water to help the filtration of pollutants, it is a mechanism of dry interception and adsorption. Whether it is a paper filter or a chemical filter, it is a consumable. After a period of use, it needs to be replaced, except that it is not environmentally friendly. The cost of the air filtration system will be increased, and the dense mesh structure designed to filter the pollutants will also cause the pressure drop when the air flows through the filter, thereby causing the efficiency of filtration. reduce.
