[0002] Biomass boiler is an environmentally friendly thermal energy equipment, but it also produces solid particles during the combustion process, and appropriate dust removal equipment is needed to purify the flue gas. The dust filter bag is a dust removal equipment dedicated to biomass boilers, which is usually used to capture and filter solid particles in the flue gas;

[0003] During the installation and use of dust filter bags, there is a problem that the bag is not tightly connected to the built-in frame, which will cause the bag to be pulled or squeezed, causing the bag to deform or be damaged, which will shorten the service life of the bag. In severe cases, the bag needs to be replaced, increasing maintenance costs. Secondly, the loose connection between the bag and the bag box will make the dust removal system unstable, affecting the filtering effect of the filter bag, making it impossible to fully capture and filter particulate matter in the flue gas, thereby reducing the dust removal efficiency. In response to the above problems, the inventor proposes a dust filter bag specifically for biomass boilers to solve the above problems. Utility Model Content
