The material of the dust bag is a cloth or felt made of synthetic fibers, natural fibers or glass fibers. If necessary, sewn cloth or felt into a cylinder or a flat filter bag. Depending on the nature of the flue gas, filter media suitable for the application conditions are selected. Generally, when the flue gas temperature is lower than 120°C and the filter material is required to have acid resistance and durability, polyester fleece and polyester needle punch felt are often used; when high-temperature flue gas (<250°C) is processed, graphitization is mainly used. Glass cloth; in some special circumstances, the use of carbon fiber filters. It is important to control the speed at which the flue gas passes through the filter material (called the filtration rate) during operation of the bag filter. Generally, the filtration rate is 0.5-2 m/min, and the particle efficiency greater than 0.1 μm can reach 99% or more, and the device resistance loss is about 980-I470Pa.
The dust bag is made of textile filter cloth and non-woven felt, and the dust-containing gas is filtered by using the filtering action of the fiber fabric.

The dust bag is a key part of the operation of the bag filter. Usually the cylindrical filter bag is suspended vertically in the dust collector.
A dust collector or a dust removal device is a device that separates dust from flue gas. The bag filter is also called a filter type dust collector, which is a dry type high efficiency dust remover. It is a dust removal device that uses a bag filter element made of fiber material to trap solid particles in a dust-containing gas. The principle of action is that the dust particles are intercepted by the collision of the fibers with the inertial force of the filter cloth fibers.
In pulse and air box type pulse dusters, dust is attached to the outer surface of the filter bag. When the dust-containing gas passes through the dust collector, the dust is trapped on the outer surface of the filter bag, and the clean gas passes through the filter material into the interior of the filter bag. The cage inside the filter bag is used to support the filter bag to prevent the filter bag from collapsing, and it helps the removal and redistribution of the dust cake.
The fabric and design of the dust bag should strive for efficient filtration, easy removal of dust, and durability. The selection of dust bag is very important. It directly affects the dust removal effect of the dust collector. The dust bag is selected from the following aspects: gas temperature, humidity and chemical properties, particle size, dust concentration, filtration speed, clearance Dust and other factors.
