The concentration of dust in the gas processed by the dust removal bag directly affects the resistance and service life of the filter bag. The thicker the dust layer on the surface of the filter bag, the greater its resistance, and the greater its impact on the service life of the filter bag. The use of flat and round filter bags in this equipment is mainly for rotary ash cleaning, and allows for a greater chance of the nozzle being aligned above the bag mouth. Select low voltage pulse method for ash cleaning. When using fiberglass coated filter bags, low-pressure pulse ash cleaning has emerged.
According to the on-site situation, each equipment can be designed as a single room, double room, or multiple rooms. Each room can be composed of one or more filter bag bundles, which is a typical modular design. Firstly, the average between rooms, followed by the average of the entire room after entering the ash hopper. In addition, when the pulse airflow is used to wash the filter bag, the higher pressure airflow inside the bag causes the contracted filter bag to rapidly expand. The filter bag will experience fiber to fiber misalignment under high pressure, and the greater the pressure, the greater the friction force on the staggered contact surface, and the shorter the service life of the filter bag. The resistance of the filter bag is proportional to the square of the filtering wind speed. If the wind speed is too high, it will cause the initial resistance to be too high, causing local "perforation" on the film, which will cause wear on the substrate and affect emissions and service life.
