The FGM air box pulse bag filter (plenum pulse) is a dust collector introduced from the American company Fuiler. This type of dust collector has advantages over other types of dust collectors, such as insufficient kinetic energy intensity during chamber blowback and simultaneous filtering and cleaning of dust with pulse blowing. Therefore, it increases the adaptability of bag dust collectors, improves dust collection efficiency, and prolongs the service life of filter bags. On the entire cement production line, not only can it be used as a dust collection equipment for crushers, dryers, coal mills, grate coolers, and cement mills, but its high concentration and rate type can also be directly used as a raw material vertical mill outlet concentration (500g/Nm) gas.
The 0-Spea powder selection machine is used for dust collection of gas with an outlet concentration of 1000g/Nm, and the dust concentration of the collected gas is less than 100g/NM. The filter bag adopts polyester needle punched felt filter material, and the average service life can reach more than two years. At present, the equipment has been widely used, not only quickly selected in cement plants, but also promoted and used in industries such as steel and carbon black.
The gas box pulse dust collector is divided into several box areas, with 32, 64, 96, 128 bags per box. And there is a lift valve driven by a cylinder on each outlet pipe of the box. When the resistance of the dust collector reaches the pre selected value (usually 1500pa), the dust cleaning controller sends a signal. The lift valve of each compartment begins to close to cut off the filtered airflow. Then the solenoid valve of this box is opened (one per box, pressure not less than 0.5MPa), and compressed air flows into the cleaned filter bag to remove the dust. After this action is completed (approximately 10-15 seconds), the lift valve on the outlet pipe will reopen, allowing the box to resume filtering work and follow the above requirements one by one until all dust is cleared.
The pneumatic pulse bag dust collector adopts a separate chamber for dust cleaning. During dust cleaning, it is isolated and rotated box by box to avoid the secondary flying problem of the jet pulse bag dust collector. At the same time, the compressed air cleaning effect is ensured. The entire box design utilizes a compartment structure, and the ash hopper can be extended to the inlet main pipe. The incoming dusty flue gas directly enters the enlarged ash hopper to achieve pre dust collection effect, and can remove horizontal straight pipes that are prone to blockage. So, the segmented pulse bag filter can not only handle dust containing gases of general concentration, but also handle dust containing gases with a concentration of up to 1000g/Nm.
This dust collector uses a full box large pulse valve for back blowing and jet cleaning. When removing the bag, open the top cover and directly remove the filter bag, making maintenance simple and versatile.
