Plate type static-electricity filter

Abstract

The invention discloses a plate type static-electricity filter. The filter comprises a filter box, wherein, one side end face of the filter box is provided with an air inlet, the other side end face of the filter box is provided with an air outlet. An ionization box is installed between the air inlet and the air outlet, the ionization box is orderly provided with an ionizing region and dust collecting region along a moving direction of air. Along a width direction of the air inlet, the ionizing region is provided with plural groups of ionization lines with high voltage and ionization grounding plates which are grounded, the ionization lines and the ionization grounding plates are in one-to-one correspondence, and are uniformly distributed with equal interval. Along a width direction of the air inlet, the dust collecting region is provided with plural groups of dust collecting high-voltage plates with high voltage and dust collecting grounding plates which are grounded, the dust collecting high-voltage plates and the dust collecting grounding plates are in one-to-one correspondence, and are uniformly distributed with equal interval. The ionization lines, the ionization grounding plates, the dust collecting high-voltage plates and the dust collecting grounding plates are all parallel with the two side wallboards of the ionization chamber. The plate type static-electricity filtercan effectively filter suspended particles in air, is easy to produce, and the cost is low.

Description

technical field [0001] The invention relates to an air filter, in particular to a plate-type electrostatic filter, which belongs to the technical field of air purification. Background technique [0002] At present, the medium-efficiency filter section of air purification often uses filter material filters such as bag filters, filters with clapboards and filters without clapboards. These traditional filter material filters have the following shortcomings: [0003] 1. High resistance, resulting in a corresponding increase in system energy consumption. [0004] 2. The dust filtration effect between 0.1μm and 0.3μm is not significant. [0005] 3. During use, when the differential pressure before and after the filter material reaches the design final resistance, a new filter needs to be replaced, and the used filter becomes garbage, causing disposal problems. [0006] On December 31, 2008, the Chinese invention patent with the publication number CN101332393 disclosed a high-vo...
