AI Technical Summary
In existing technologies, it is difficult to actively remove the scattered small clumps on the inner wall of the dust hopper of a bag filter in the early stages, and wet cleaning will generate industrial wastewater, resulting in unstable cleaning effect and increased cost.
By employing a gelation bonding method, scattered small clumps are bridged into a large, integral clump through a gel reaction medium, and then vibratory fragmentation technology is used to cause its brittle fracture. Combined with the application of a protective film and dry cleaning, waterless removal is achieved.
It achieves efficient removal of scale buildup on the inner wall of the ash hopper, avoids the generation of industrial wastewater, reduces cleaning frequency and cost, and keeps the removed material dry so that it can be directly incorporated into the dry ash conveying system.
