Efficient and energy-saving pulse bag filter is a thousand type dust filtering device. Its basic mechanism is that when dust containing gas passes through the box equipped with a filter bag, the dust inside is blocked by the filter bag and purified, and the dust is discharged centrally. Bag dust collectors have the following characteristics: high dust removal efficiency, high capture efficiency for fine dust, strong adaptability, ability to handle various types of dust, and insensitivity to dust characteristics. When the concentration of dust in the inlet gas changes significantly, it does not affect the dust removal efficiency, with a dust removal efficiency of over 99%, and can achieve ultra-low emissions of
