Dust bag; It can be called the heart of bag filter, generally referred to as filter bag, dust filter bag, dust collection bag, dust accumulation bag, dust removal bag, dust collector bag, etc. The dust removal bag is a crucial part of the operation of the bag filter, usually a cylindrical filter bag suspended vertically in the dust collector.

Dust collector or dust removal equipment is a device that separates dust from flue gas. The bag filter, also known as the filter type dust collector, is a dry dust collector that uses bag filter elements made of fiber woven fabric to capture solid particles in dusty gases. The principle of its action is that dust particles are intercepted when they collide with the fibers of the filter cloth due to inertial force when bypassing the fibers.

Flue gas treatment and dust removal systems for ironworks, steelmaking plants, ferroalloy plants, refractory plants, foundries, power plants, etc. Flue gas filtration for waste incinerators, coal-fired boilers, fluidized bed boilers, etc. Asphalt concrete mixing, building materials, cement ceramics, lime, gypsum and other production sites. Aluminum electrolysis, filtration of smelting flue gas for lead, tin, zinc, copper and other metals, recovery of fine materials, and separation of liquid and solid. Liquid solid separation and fine material recovery in chemical, coke, carbon black, dyes, pharmaceuticals, plastics, and other industries. Dust control and purification collection in mining, grain processing, flour, electronics industry, wood processing, etc.

Production standards for dust removal bags:

The longitudinal stitching of the dust removal bag should be firm, straight, and not less than three The circular stitching of the dust removal bag opening shall be firm and not less than two The circular stitching of the anti collapse ring of the dust bag should be firm and not less than two on each side The circular stitching at the bottom of the dust removal bag is allowed to be single, but sewn in two or more circles The deviation of the length dimension of the dust removal bag during cutting is ± 10mm. The sewing needle code around the dust removal bag should be uniform, and the longitudinal needle code of the bag should not be less than 15 needles/10cm, and the transverse needle code should not be less than 12 needles/10cm; The sewn cloth bag must not have any holes, damages or defects; Bags with a diameter greater than 200mm and a length greater than 5000mm should undergo a tensile test, and their elongation should meet the requirements.
