[0002] Dust collector filter bags are a type of high-efficiency dust collection media, characterized by good air permeability, high dust removal efficiency, and certain resistance to acids, alkalis, and heat. The filter bag is the heart of a baghouse dust collector. Typically, cylindrical pulse-jet filter bags are vertically suspended within the dust collector. Dust-laden gas enters the dust collector through the inlet, and after passing through the guide plate in the ash hopper, some large dust particles are separated by inertial force and fall directly into the ash hopper. The dust-laden gas then enters the filter bag filtration zone within the outer frame, where the vast majority of dust is captured on the outer surface of the filter bag. Clean gas passes through the filter media into the interior of the filter bag, and the purified gas passes through the filter bag opening into the upper outer frame before being discharged through the outlet.

[0003] For example, the utility model application with application number CN202021409094.5 discloses a dust collector filter bag. The dust collector filter bag of this utility model has an elastic element set between the first section and the second section of the support rod. During the dust removal process, the support rod can vibrate longitudinally, thereby providing dust removal for the filter bag. However, the existing dust collector filter bags require multiple fixing methods to install the bag mouth and the filter frame inside the dust collector, which is cumbersome.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a dust removal filter bag that combines polyester and filter cloth. Utility Model Content
