Gas box type blowing wind pipe dust removing device

Abstract

The invention discloses a gas box type blowing wind pipe dust removing device, which comprises a box body, wherein the box body comprises a wind inlet box body, a filtering box body and an ash hopper,the wind inlet box body, the filtering box body and the ash hopper are distributed up and down, a wind inlet is formed in the wind inlet box body, an ash outlet is formed below the ash hopper, a group of blowing wind pipes are arranged in the filtering box body, a plurality of flange interfaces are arranged on the upper end surfaces of each blowing wind pipe, a filtering cylinder can be vertically mounted on each flange interface, the two ends of the blowing wind pipe extend out of the box body, pulse valves connected with a gas source are arranged on each blowing wind pipe on the same side of the box body, off-line valves are arranged on each blowing wind pipe on the other side of the box body, the blowing wind pipes on one sides of the off-line valves are communicated with a wind outletgathering pipe, and a fan is arranged on the wind outlet gathering pipe. According to the invention, by increasing the diameter of the blowing wind pipe, the filtering cylinder is directly mounted onthe blowing wind pipe to increase the flow of the gas flow in the blowing wind pipe, so that the back blowing operation of the filtering cylinder is well realized; and the gas box type blowing wind pipe dust removing device is simple in overall structure, convenient to mount and convenient to maintain.

Description

technical field [0001] The invention relates to the field of dust removal equipment, in particular to an air box-type dust collector for spraying blow pipes. Background technique [0002] The filter cartridge dust collector is composed of a filter cartridge as a filter element or a dust collector using pulse injection. The dust-laden gas enters the box through the air inlet, and then passes downward through the filter cartridge, and the dust is collected on the outer surface of the filter cartridge, and the filtered clean air passes through the center of the filter cartridge and is discharged through the air outlet pipe. When the dust accumulates on the surface of the filter cartridge and the resistance increases and reaches the set value, the pulse valve is opened, and the compressed air is directly sprayed into the center of the filter cartridge to remove the dust attached to the outer surface of the filter cartridge, and the dust particles fall into the dust bucket.
