Embodiment

[0021] An air filter, which has an air inflow end 1, an air outflow end 2, a filter medium 3 and a support part for supporting the filter medium 3, and the support part is arranged between the air inflow end 1 and the air outflow end 2 A spray generating device 4 is installed on the side of the filter medium 3 towards the air inflow end 1, and the spray generated by the spray generation device 4 is located on the path where the air flows from the air inflow end 1 to the filter medium 3.

[0022] In this embodiment, the filter medium 3 includes a first layer of filter cloth layer 31, a filter fiber layer 32 and a second layer of filter cloth layer 33 stacked in sequence, and the first layer of filter cloth layer 31 and the second layer of filter cloth Layer 33 can be disassembled for easy cleaning;

[0023] In order to ensure the filtering effect, the density of the first layer of filter cloth layer 31 of the filter medium 3 is less than the density of the second layer of filte...

Abstract

The invention belongs to the field of air filtering, and particularly relates to an air filter. The air filter is provided with an air flow-in end, an air flow-out end, a filtering medium and a support part used for supporting the filtering medium, wherein the support part is arranged between the air flow-in end and the air flow-out end; a spray generating device is arranged at one side, facing the air flow-in end, of the filtering medium; spray generated by the spray generating device is positioned on a path of the air flowing from the air flow-in end to the filtering medium. The efficient filtering on the air can be realized; the effective protection on elements can also be realized.

Description

technical field [0001] The invention belongs to the field of air filtration, in particular to an air filter. Background technique [0002] The air filter device includes an air passage, a first air filter installed in the air passage, wherein the first air filter includes a filter frame and a filter body, the filter frame is provided with at least one passage for air circulation, The filter body includes electrostatically chargeable fibers attached to the filter frame such that the filter body achieves a predetermined flow direction from the filter frame to a predetermined flow direction relative to air flowing through the air channel at a certain distance downstream from the filter frame. The extension at the distance position. When air flows through a first air filter of the type described above, the fibers in the filter body move relative to each other, thereby rubbing against each other. The friction created when air flows over the fibers keeps the fibers electrostatic...
