Introduction to the specific use of dust removal bags
Date: 2025-08-15Read: 30
The effectiveness of dust removal bags is related to various factors, but primarily depends on the filter material. The filter material of the dust removal bag is a cloth or felt woven from synthetic fibers, natural fibers, or glass fibers. Sew the cloth or felt into cylindrical or flat filter bags as needed. Select filter media suitable for the application conditions based on the properties of the flue gas.
Usually, when the flue gas temperature is below 120 ℃ and the filter material is required to have acid resistance and durability, polyester velvet cloth and polyester needle punched felt are often selected; When dealing with high-temperature flue gas (<250 ℃), graphitized glass fiber cloth is the primary choice; In some special cases, carbon fiber filter media should be used.
Controlling the speed at which flue gas passes through the filter material during the operation of the dust removal bag (referred to as the filtration speed) is quite important. Generally, the filtration speed is 0.5-2m/min. For speeds greater than 0.1? The particle power of m can reach over 99%, and the equipment resistance loss is about 980-I470Pa. The plan is innovative and adopts an intake structure, where coarser high-temperature particles directly fall into the ash hopper, effectively protecting the filter bag.
The use of a compartment separation line for dust cleaning has high power and less secondary adsorption of dust, which effectively reduces equipment energy consumption. The fatigue level of filter bags and pulse valves also decreases accordingly, doubling the life of filter bags and valve plates and reducing equipment operation and maintenance costs.
