Influence of pulse valve injection quantity on dust-cleaning performance of cartridge filters

On the pulse-jet experimental table, using the orthogonal pulse valves with the two sizes of calibers of 3/4 in. and 1 in., changes jetting pressure and pulse width respectively, compares and analyses the single-injection quantity of the pulse valve and the influence on the positive pressure peak on the side wall of the cartridge.The results show that the higher jetting pressure is, the larger single-injection quantity is; the pulse width has some influence on the single-injection quantity, the influence at high jetting pressure is smaller than that at low jetting pressure; the 1 in. pulse valve has the larger single-injection quantity when jetting pressure remains the same; the 1 in. pulse valve using lower jetting pressure has smaller positive pressure peak on the side wall of the cartridge when the once injection quantity is the same, but the peak is larger than that of the 3/4 in. pulse valve using the same low jetting pressure.
