Description

Pulse dust collector Technical Field The invention relates to the technical field of dust collectors, in particular to a pulse dust collector. Background The bag type dust collector is the device with the highest dust collection efficiency in dry dust collection equipment, and is widely applied to industries such as electric power, metallurgy, chemical industry, mine, grain processing, garbage incineration, building materials and the like, dust-containing gas flows through a filter bag under the action of pressure, is filtered through the filter bag, dust in the dust-containing gas is blocked on the outer surface of the filter bag to form a dust layer, the dust layer is blown into an ash bucket through an ash removal device, clean gas after filtration passes through the filter bag, and is discharged into the atmosphere from a clean gas chamber. In the running process of the existing bag type dust collector, when dust-containing gas enters the bag type dust collector, a more obvious problem often exists, because the dust-containing gas which is not subjected to pretreatment is directly discharged into a cloth bag treatment box, a series of adverse effects can be caused by the operation mode, firstly, the air flow in the bag type dust collector is increased instantaneously at the moment of gas entering, under the condition, a large amount of dust which is wrapped in the air can be blown towards a certain specific position directly under the drive of strong air flow, thus, the collected dust is difficult to be dispersed uniformly in the bag type dust collector, the uneven distribution condition can have extremely adverse effects, such as cloth bags which are opposite to the position of an air inlet, the blocking phenomenon can occur quickly due to the fact that most of dust is impacted and accumulated, and the cloth bags which are positioned at the rear position are almost in contact with each other, so that the dust is difficult to have an ideal filtering effect on the dust, the difference between the front and rear cloth bags is difficult to have a serious adverse effect on the dust collecting efficiency of the whole bag type dust collector, and the dust collector is difficult to finish the dust collector. Disclosure of Invention The invention provides a pulse dust collector, which solves the problems that dust in gas is driven by air flow to blow directly to one position in the related art, accumulated dust is difficult to disperse in a bag dust collector, so that a cloth bag facing an air inlet is easy to cause blocking quickly, and the cloth bag at the rear is difficult to have a better filtering effect on the dust, so that dust collection efficiency is easy to influence.
