Background
The bag type dust collector is a dry dust filtering device for collecting solid particles in dust-containing gas by utilizing a bag-shaped filter element made of fiber fabrics, is suitable for collecting fine, dry and non-fibrous dust, and consists of an upper box body, a middle box body, a lower box body, a dust cleaning system, a dust discharging system and other structures; the working principle is as follows: when the dust-containing gas passes through the filter layer, dust particles in the gas flow are intercepted and trapped by the filter layer, so that gas-solid separation is realized; after the resistance of the dust remover reaches a certain value, dust is removed in time to avoid the efficiency reduction;
the existing pulse blowing ash removal mode is that high-pressure air (more than 0.3Mpa) is blown into a filter bag at a high speed within 2 seconds, so that the filter bag generates pulse expansion vibration from inside to outside, and the outer surface of the filter bag obtains great acceleration, thereby shaking off a dust layer on the surface; because the length of the dust removal bag is longer, the stress of the dust removal bag close to the blowing opening is larger, the dust removal effect is good, and the stress of the dust removal bag far away from the blowing opening is smaller, and the dust removal effect is poor; the upper end of the dust removal bag needs to bear larger air pressure, so that the dust removal bag is easy to damage, the use cost is increased, and an ideal cleaning effect cannot be achieved only by blowing.
