Embodiment Construction
[0046] Small bag-type dust collectors are generally online dust removal. In the dust removal strategy, first of all, establish the concept of pulse valve numbering, and number the pulse valves of all boxes from the beginning to the end. The number is recorded as num, and num is from 1 to m* The number of n (m, the number of pulse valves in each box; n, the number of boxes); then, set the number of interval pulse valves Δnum (0<=Δnum<num); finally, the cleaning strategy is based on the two values of num and Δnum data to realize jump cleaning. In the ash conveying and unloading strategy, first, when receiving the ash conveying and unloading start command for the first time, start the dust-free ash unloading device or bucket elevator in sequence, and start the scraper machine after a delay; then, open the No. 1 ash hopper to unload Ash valve, after the ash discharge valve of No. 1 ash hopper is closed, open the ash discharge valve of No. 2 ash hopper in a delayed manner. If th...
