Baffle plate box type filter element in use for pulse self-cleaning type air filter

Abstract

The invention relates to a self-cleaning pulse air strainer with the partition board box-type filter element, the net locates outsides, and the frame sited all around, in the frame there is a draught excluder strip, some partition boards locate in the center of the filter element, and the filter paper is between the partition boards. The partition board is made by the aluminum handkerchief with a tile-edge form, the contour of it has a square shape module type, which can intercept the dust granule effectively, and not form the oversized resistance to the air current, and the filter fineness can achieve 0.3mum. The partition board box-type filter element with 80% textile fibers, 20% polyester synthesis filter paper has a belt partition board's box-type filter element which the filter fineness progressive raises, this partition board uses the aluminum handkerchief to make the corrugated shape, which enhances filter paper's effective filtration area, reduces the low resistivity rate, and increases accommodates the quantity of dust, it solves the problem of losing the filter efficiency because of the combination of the filter paper along with the increasing pressure. The textile fiber polyester composition material can filter effectively the tiny dust pellet and let it on the material surface, which strengthens the effect of clearing ash by pulse, and lengthens the filter element's life.

Description

technical field [0001] The invention relates to a partition box-type filter core for a pulse self-cleaning air filter, which can effectively intercept dust particles without forming excessive resistance to air flow. It belongs to the technical field of air filters. Background technique [0002] The existing filter element is a traditional cylindrical filter element. The filter paper used in China is formed by a polyester fiber by acupuncture. It is easy to backwash when it is made into a drum. At present, the best filter paper in China can only reach Medium-efficiency, most of them are between 1-5μm, imported materials can reach 0.3-0.5μm, that is, high-efficiency and sub-high-efficiency filter paper, such as making imported high-efficiency filter paper into a cylindrical filter at one time to achieve a filtration accuracy of 0.3μm , It is also possible, but its consumption has indeed increased. Originally, the filter barrel should be replaced once every 1-2 years, but it h...
