Pulse dust collector

The pulse dust collector is a new type of high-efficiency dust collector . It combines the advantages of various pulse jet dust collectors with sub-chamber back-blowing, and overcomes the shortcomings of insufficient cleaning intensity of the sub-chambers and uneven distribution of incoming and outgoing air. Expanded the scope of application.

Product Description

 

The pulse dust collector is that when the dust-laden gas enters the dust collector from the air inlet, it first encounters the inclined plate and baffle plate in the middle of the air inlet and outlet, and the air flow turns to flow into the ash hopper. At the same time, the air flow speed slows down. Dust flows directly into the ash hopper. It plays the role of pre-dust collection. The airflow entering the ash hopper is then folded upwards and passes through the filter bag with a metal frame inside. The dust is captured on the outer surface of the filter bag. During the process of purifying the dust-containing gas through the filter bag, the dust accumulated on the filter bag increases with the increase of time, which increases the resistance of the filter bag and causes the processing air volume to gradually decrease. In order to work normally, it is necessary to control The resistance is within a certain range (140--170 mm water column). Once the range is exceeded, the filter bag must be cleaned. When cleaning the dust, the pulse controller will trigger each control valve in sequence to open the pulse valve, and the compressed air in the air bag will be released by the injection pipe. Each hole is sprayed into each corresponding filter bag, and the filter bag expands rapidly in an instant, so that the dust accumulated on the surface of the filter bag falls off, and the filter bag returns to its original state. The cleaned dust falls into the ash hopper and is discharged from the body through the ash discharge system. In this way, the dust accumulated on the filter bag is periodically pulsed to clean the dust, so that the purified gas can pass normally and ensure the operation of the dust removal system.
