Product introduction：
With the further improvement of the national dust emission concentration standards for the power industry, bag filters with high dust removal efficiency have been widely promoted in the power industry.
Currently, among the bag filters used in power plants, the long arm rotary tube nozzle bag filter is widely welcomed by users in the power industry due to its suitability for handling high air volume dusty gases, low maintenance workload of pulse valves, large blowing volume, low pressure, and the ability to save a lot of energy. It has broad development space. The pulse valve in the bag filter, as the "heart" component of the dust cleaning system, is generally a large valve imported from abroad with a diameter of more than 8 inches, while the valve diameter produced domestically is mostly less than 3 inches, which cannot meet the requirements of its large blowing volume. Our company's scientific researchers have made unremitting efforts to adapt to the requirements of the rapidly developing environmental
protection industry and have developed large-diameter pulse valves with specifications such as 8 inches, 10 inches, 12 inches, 14 inches, and 16 inches.
Product features：
The rotary cleaning large-diameter pulse valve uses a three-stage diaphragm structure to ensure unloading and exhaust matching, inflation damping matching, and high control and blowing sensitivity of the pulse valve, with good flowability.
Greatly increases the blowing air volume of the pulse valve, greatly enhances the power output of the pulse valve. Greatly reduces the blowing pressure of the pulse valve, ensuring economical, stable, and reliable operation.
The gas supply pressure is less than 0.1MPa, compressed air is used, which is not affected by the simultaneous use of gas in the pipeline network, and the operation is stable and reliable.
Low gas supply pressure, Roots blower can be used for gas supply, cheap equipment, simple management, economical operation, and convenient use.
The rotary cleaning large-diameter pulse valve is manufactured as an integrated unit with the compressed air tank. After one-time installation, the pulse valve with large volume and weight is extremely convenient for disassembly and maintenance.
