Description

Technical Field

[0001] The utility model relates to the technical field of bag dust removal, in particular to a dust removal bag installation structure which is convenient for dust cleaning. Background Art

[0002] Bag filter, also known as filter filter, is a dry high-efficiency dust collector. It is a dust removal device that uses a bag filter element made of fiber weaving to capture solid particles in dust-containing gas. Its working principle is that dust particles are intercepted by colliding with the fibers due to inertia when passing around the filter cloth fibers. During the dust removal process, the bag will slowly adhere to layers of dust, reducing the dust removal efficiency.
