What is the function of the high temperature dust filter bag?


The dust bag is called the heart of the bag filter. It is generally called the dust filter bag and the dust filter bag. The dust bag is an important part of the bag filter in operation. Usually, the cylindrical filter bag is hung vertically on the dust collector. Vacuum cleaners and dust removal equipment are equipment that separates dust from smoke. Bag vacuum cleaners, also called filter vacuum cleaners, are dry high-efficiency vacuum cleaners. They are vacuum cleaners that use cloth bag filter elements made of fiber woven fabrics to capture solid particulate matter in dust-laden gases. The principle of action is that dust particles are intercepted by collision with the fibers due to inertial force when they wind around the filter cloth fibers. In pulse and air box pulse vacuum cleaners, dust adheres to the outer surface of the dust bag. When the dust-containing gas passes through the vacuum cleaner, the dust is trapped on the outer surface of the filter bag, and the clean gas enters the filter bag through the filter material. The cage inside the filter bag is used to support the filter bag, prevent the filter bag from collapsing, and at the same time help the redistribution of the dust cake.


High-temperature dust filter bag.


The fabric and design of high-temperature-resistant dust filter bags should pursue filtration, easy dust removal and durability as much as possible. The selection of high temperature resistant dust filter bag is very important, which directly affects the dust removal effect of the dust collector. The choice of dust filter bag is selected from factors such as gas temperature, humidity and chemistry, particle size, dust concentration, filter wind speed, and dust removal method. It is applied to flue gas management and dust removal systems in ironworks, steelworks, ferroalloy plants, refractory plants, foundries, power plants, etc. Waste incinerators, coal-fired boilers, fluidized bed boilers and other flue gas filtration. Asphalt concrete mixing, building materials, cement ceramics, lime, gypsum and other production sites. Aluminum electrolysis, lead, tin, zinc, copper and other rare metal smelting flue gas filtration, fine material recovery, liquid and solid separation. Liquid fixed separation and fine material recovery in the chemical industry, coke, carbon black, dyes, pharmaceuticals, plastics and other fields. Dust management and purification collection in mining, grain processing, flour, electronics industry, wood processing, etc. The appearance of the dust bag is leaking, the air temperature in the bag room is lower than the dew point, the filter bag is humid, the dust is not loose, it sticks to the filter bag, blocking the fabric hole, the dust is invalid, the vacuum cleaner is too large to continue to operate, and sometimes sticks to the filter on the filter bag
