[0002] The bag dust collector is suitable for capturing fine, dry, non-fibrous dust. The bag dust collector is a dry dust filtering device. After the filter material has been used for a period of time, a layer of dust accumulates on the surface of the filter bag due to screening, collision, retention, diffusion, static electricity and other effects. This layer of dust is called the primary layer. In the subsequent movement process, the primary layer becomes the main filtering layer of the filter material. Relying on the effect of the primary layer, the filter material with a larger mesh can also obtain a higher filtration efficiency. When the bag dust collector is dealing with high-humidity dust removal air, the moist dust is very easy to adhere to the surface of the filter bag and cause blockage, thereby affecting the reliability of dust removal.
