Description

Ejector device of pulse bag-type dust collector

Technical Field

The utility model belongs to the technical field of dust remover equipment, and particularly relates to an ejector device of a pulse bag-type dust remover.

Background

The pulse bag dust collector set consists of an air inlet chamber, an ash discharge chamber, a filter chamber, an air purifying chamber, a fan, a blowing ash removal device and the like.

The working principle of the pulse bag-type dust collector is as follows: when the dust-containing gas enters the filter chamber through the air port and passes through the filter bag from outside to inside, the dust is blocked on the outer surface of the filter bag, and the purified gas enters the bag and is discharged into the atmosphere from the air outlet through the ejector and the air purifying chamber. When the dust on the surface of the filter bag is continuously increased to cause the resistance of the equipment to rise to a set value, the micro-differential pressure controller outputs a signal, and the control instrument sends out a signal to enable the blowing system to work. The compressed air is directly sprayed out through the round holes on the output pipe and is downwards sprayed at the speed of sound, a certain vacuum is formed at the upper part, partial air in the air purifying chamber is induced (called as secondary air flow), and dust adhered to the outside of the filter bag and among fibers is blown down, so that the filter bag is cleaned. The dust separated by cleaning falls to a dust discharge port to be discharged, and the filter bag is in a filtering state after the spraying and blowing are finished.

Because the dust outside the cloth bag is not uniformly distributed, the dust can be better removed by properly adjusting the spraying angle and the spraying state.
