The Plenum Pulse dust collector is a high-efficiency dust collector introduced from the American company Fuiler, which has the technological level of the 1990s. This type of dust collector has the advantages of various types of dust collectors, such as chamber back blowing and pulse spraying, which overcome the disadvantages of insufficient kinetic energy intensity during chamber back blowing and simultaneous filtering and cleaning of dust with pulse spraying. 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, it can not only be used as a dust collection equipment for crushers, dryers, coal mills, grate coolers, cement mills, and packaging machines, but its high concentration and high efficiency type can directly serve as a dust collection device for the outlet concentration (500g/Nm) gas of the raw material vertical mill and the outlet concentration (1000g/Nm) gas of the O-Spea powder selector. The dust concentration of the gas after dust collection is less than 100g/Nm, and the filter bag adopts polyester needle punched felt filter material, with a service life of more than two years. At present, the new equipment has been widely used, not only quickly adopted in cement plants, but also promoted in industries such as steel and carbon black.

 

The pneumatic pulse bag dust collector is divided into several box areas, with 32, 64, 96, 128 bags per box. And there is a cylinder driven extension valve on the side outlet pipe of each 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 the first chamber begins to close to cut off the filtered airflow. Then the solenoid valve of this box is opened (one for each box, with a pressure not lower than 0.5Mpa), and compressed air flows in to remove the dust on the filter bag. After this action is completed (approximately 10-15 seconds), the lift valve on the outlet pipe will reopen, allowing the chamber to resume filtering work and follow the above requirements one by one until all dust is cleared.

 

The gas box pulse bag dust collector adopts a split box dust cleaning method. During dust cleaning, it is isolated and rotated box by box to avoid the problem of secondary flying of the spray type pulse bag dust collector. At the same time, the compressed air cleaning effect is ensured. The entire box design utilizes the structure of the inlet and outlet main pipes. The ash hopper can be extended below the inlet main pipe, allowing the incoming dusty flue gas to directly enter the expanded ash hopper to achieve pre dust collection effect, and can remove horizontal straight pipes that are prone to blockage. So, the gas box pulse bag dust collector can not only handle general concentrations of dusty gases but also handle dusty gases with concentrations up to 1000g/Nm.

 

This dust collector uses a full box large pulse valve to blow back and spray clean dust. When removing the bag, open the top cover and directly remove the filter bag, making maintenance simple and convenient. Overcoming the tedious process of removing nozzles, Venturi, and other components during spray bag replacement.
