Description

A workshop air dust removal device

technical field

The utility model relates to the technical field of dust removal equipment, in particular to a workshop air dust removal device.

Background technique

Dust collector is a device that separates dust from flue gas, called dust collector or dust removal equipment. The performance of the dust collector is expressed by the amount of gas that can be handled, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life and difficulty of operation and management of the dust collector are also important factors to consider its performance. Dust collectors are commonly used facilities in industrial production.

The existing dust collectors on the market use a motor to drive a fan to generate wind energy, and then use a filter bag to filter the dust-laden gas through the filter bag, and the dust is retained on the bag surface, and the clean air passes through the bag mouth to the clean air chamber, and is discharged into the atmosphere by the fan , when the dust on the surface of the filter bag continues to increase, the program controller starts to work, and the pulse valves are opened one by one, so that the compressed air can be blown to the filter bag through the nozzle to clean the filter bag, so that the filter bag suddenly expands, and under the action of the reverse air flow, the bag is given The dust on the surface quickly leaves the filter bag and falls into the ash bin, and the dust is discharged by the ash discharge valve.

The filtering effect of the existing filter bag is not obvious, and the dusty gas still contains dust after passing through the filter bag. When this gas enters the inside of the machine, it will cause damage and blockage of the machine, and when it is discharged into the atmosphere, it will cause air pollution. The filter bag is easily damaged during use, and it is troublesome to replace, which will increase the maintenance cost. The dust collector has a large volume, occupies the ground area, and has a complicated structure.
