[0002] Flame retardant antistatic dust bag is specially designed for flammable dust. In various industrial dust removal fields, the properties of dust are different. Different dusts have corresponding dust bags, which are generally selected according to the temperature of the dust-containing gas. The filter bag has excellent chemical stability and heat resistance. It is the highest performance representative in the filter material industry and the most high-end variety among all commonly used filter materials. It has reached a high level in terms of filtration efficiency and filtration accuracy.

[0003] In order to ensure the internal environment of the furniture factory during production, ventilation holes are usually set on the walls of the furniture factory, and filter bags with flame retardant effects are set at the ventilation holes to collect the dust generated during the production and cutting of wooden furniture. However, dust usually accumulates inside the filter bags during use. If there is too much dust accumulation, the filter bags need to be disassembled, cleaned and replaced. If they cannot be cleaned or replaced in time when there is too much dust accumulation, the subsequent filtering effect will be affected. Therefore, we proposed a flame retardant filter bag for furniture factories to solve the above problems. Utility Model Content
