Novel air filter bag

Abstract

The invention discloses a novel air filter bag which mainly comprises a large filter bag and small filter bags, wherein the small filter bags are positioned in the large filter bag; the filter area of each small filter bag is 50 percent of that of the large filter bag; the small filter bags are adhered to the large filter bag through thermal melting; the small filter bags are also adhered to one another through the thermal melting. Under the conditions that an air conditioning box is small and the air volume is large, a filter frame is not required to be replaced; a small filter bag page technology is additionally adopted in a conventional filter bag page, so that 50 percent of the filter area is increased in the original filter area; furthermore, bag pages are adhered to one another through the thermal melting by using a high-frequency technology; the ventilating intensity of the bag pages is improved; at high air speed, the filter effect can not be affected by the adhesion of the bag pages; the aims of saving energy and reducing the cost are fulfilled.

Description

technical field [0001] The invention relates to the technical field of air purification devices, in particular to a novel air filter bag, which is applied to various air purification equipment. Background technique [0002] As a filter element, the filter bag is a key part of the filtration process. The quality of the filter bag largely determines the filtering effect of the user. The application document with the application number 00220835 discloses a high-strength dust filter bag, including a cylindrical bag body sewn from filter cloth, the filter cloth is interwoven by warp yarns and weft yarns, and its improvement is the The weft yarn is formed by twisting a group of glass fibers with a group of flexible synthetic fibers. However, this filter bag only improves the prior art in terms of material, and is no different from the traditional filter bag in terms of structure, which also limits the further improvement of the filter bag in filtering performance.
