Description

Technical Field

[0001] The utility model relates to the technical field of dust removal polyester filter bags, in particular to a heat-resistant polyester filter bag used for dust removal equipment. Background Art

[0002] Polyester filter bag is a filter bag made of polyester fiber. Its main function is to filter particulate matter. The filter bag is a key part in the operation of bag-type dust removal equipment. It is mainly used for dust removal on dust removal equipment. Usually, the cylindrical filter bag is hung vertically in the dust removal equipment. The dust-laden airflow passes through the filter bag, and the particulate matter is blocked on the outer surface of the filter bag. The clean gas is discharged through the filter bag.

[0003] Existing filter bags sometimes need to filter and purify high-temperature furnace gas and smoke, so the filter bags need to have high heat and high temperature resistance to withstand high temperature environments. For example, an anti-static dust removal filter bag disclosed in announcement number CN218306787U does not have a multi-layer high-temperature resistant structure, which reduces the heat resistance of the filter bag. However, the filter bag may soften, deform or even melt if used in a high temperature environment for a long time, resulting in an enlarged pore size or fiber melting, thereby reducing the filtration efficiency. High temperature will accelerate the aging process of the filter bag material, resulting in a greatly shortened life of the filter bag, requiring frequent replacement.

[0004] Therefore, it is necessary to invent a heat-resistant polyester filter bag for dust removal equipment to solve the above problems. Utility Model Content
