Bag type dust collector

Abstract

The invention discloses a bag type dust collector which comprises a bag type dust collecting device. The bag type dust collecting device comprises a dust collecting case and a cloth bag assembly, wherein the cloth bag assembly is arranged in the dust collecting case, a first-stage cyclone dust collecting unit is provided out of the bag type dust collecting device, an air outlet of the first-stage cyclone dust collecting unit is connected with an air inlet of the bag type dust collecting device, the top of the dust collecting case is provided with a rotary rod, the cloth bag assembly is connected with the rotary rod, a rocking bar is vertically arranged out of the dust collecting case, and the rocking bar is connected with the rotary rod. According to the invention, after gas containing particles and dust passes through the first-stage cyclone dust collecting unit of the bag type dust collector, the content of particles and dust in the gas is substantially reduced, which enables only a small amount of particles and dust to adhere onto the surface of the cloth bag assembly; then the rocking bar is turned to allow the rotary rod to rotate so as to further achieve the purpose of enabling the particles and dust adhering onto the surface of the cloth bag assembly to fall by vibrating the cloth bag assembly, which enables consumption of energy to be greatly reduced, thereby reducing production cost of enterprises.

Description

technical field [0001] The invention relates to a dust collector, in particular to a bag-type dust collector, and belongs to the technical field of devices for filtering gas in operation and transportation. Background technique [0002] A dust collector is a device that separates dust from flue gas. There are many types of dust collectors, among which pulse bag filter is a relatively new type of dust collector, which is mainly composed of dust removal box, bag group, ash hopper, pulse device and ash storage device, etc. The bag group is set in the dust collector In the box, there is an ash hopper under the dust removal box, and an ash storage device under the ash hopper. The pulse device is used to control the vibration of the bag group to clean the ash. The gas containing particles and dust enters the dust removal box from the air inlet. The gas containing particles and dust suddenly increases in volume and the flow rate decreases. Some larger particles and dust will fall ...

AI Technical Summary

Problems solved by technology

Such a pulse bag filter does not have a first-stage dust removal device. Close to the collision between particles and dust and the fall of its own weight will cause too much adsorption of particles and dust on the surface of the bag group, which increases the opening time of the pulse device and consumes a lot of energy. cost of production
