Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a spray gas storage tank fixing device for a bag type dust collector. Background Art

[0002] The jet air tank fixing device for bag filter is a dry dust filtering device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-laden gas. When the dust-laden gas enters the bag filter, the large particles and heavy specific gravity settle down due to the action of gravity and fall into the ash hopper. When the gas containing fine dust passes through the filter material, the dust is retained and the gas is purified. When the dust-laden gas passes through the filter bag for purification, more and more dust is accumulated on the filter bag with the increase of time, which increases the resistance of the filter bag and causes the processing air volume to gradually decrease. For normal work, the resistance must be controlled within a certain range (140-170 mm water column), and the filter bag must be cleaned. During cleaning, the pulse controller sequentially triggers each control valve to open the pulse valve, and the compressed air in the air storage tank is sprayed into the corresponding filter bag through the venturi tube from the holes of the blowing pipe. The filter bag expands sharply in an instant, so that the dust accumulated on the surface of the filter bag falls off and the filter bag is regenerated. During the use of bag dust collectors, pulse valves, injection pipes, venturi tubes and gas tanks will more or less malfunction, or require cleaning after long-term use. If disassembly is inconvenient, it will affect work efficiency and increase work difficulty.

[0003] Based on the above problems, the utility model proposes a spray air tank fixing device for a bag dust collector. Utility Model Content
