Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collector detection, in particular to a bag dust collector broken bag detection device. Background Art

[0002] Bag filter is a dry dust filter. 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 dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified. Most industrial and mining enterprises use box-type bag filter to control flue gas and dust pollution. The filter bag plays a filtering role on dust in the dust collector. During the operation of the dust collector, the filter bag will be damaged due to the influence of wind speed, flue gas temperature, pulse cleaning, etc. The filter bag needs to be replaced in time if it is damaged, otherwise the flue gas and dust pollution will not meet the emission standards.

[0003] The traditional dry dust bag leak detection method is that personnel wear air respirators, and more than two people place the physical leak detection piece of the bag on the dust detection leak detection port by hand, manually open the valve handle, and check whether there are large particles on the sample after the gas is blown out, so as to determine whether the gas entering the generator set meets the standards. This method produces a large amount of smoke and dust that affects the health of the workers. Utility Model Content
