[0005] The beneficial effects of the utility model are as follows: 1. The large-caliber pulse valve is adopted, the pulse valve is large in size and high in strength, the diaphragm is significantly thickened and strengthened, and the service life of the pulse valve is greatly extended. 2. The pulse cleaning pressure is lower than that of the commonly used bag dust collector, which can extend the service life of the filter bag. 3. The number of pulse valves is small, and it is easy to determine the location of the pulse valve fault point, so the cleaning system runs stably and reliably, and occupies a small area, thereby saving production costs.
