The drain water in the bag filter dust bag dust during handling, the gas contains more moisture and dust and moisture and easy deliquescence oil dust may be generated on the surface of dust or water film increases adhesion film, Although this helps to trap the dust, but cleaning will be difficult. Especially in high humidity and high-temperature gas state, due to the cooling effect of the outside air to produce condensation. This not only makes the dust trapped in the bag surface fouling, or even blocked, and can corrode structural materials, so that dust collector running resistance increases directly affect the normal operation of the baghouse. In view of this, the general media must be further enhanced in functionality to accommodate this particular working conditions, prevent or reduce dust paste bag, and enhanced filter life and work efficiency. Our factory is equipped with the most advanced media finishing equipment, product by singeing, calendering, dipping, coating, drying and styling, etc. Process. Finishing technology can be of various woven needle punched filter felt and filter for water repellent and oil processing. Water repellent and oil filter needle felt production processes: fiber opening - carding - lapper - Pre thorn - the main thorn - singeing, calendering - impregnated water repellent and oil - drying - stereotypes - Finished rejected by various media water and oil repellent treatment, it does not absorb water, the surface having hydrophobic properties, in the application to prevent the paste bag, without pore blocking, easy cleaning, and there is acid, alkali and other chemical properties. Compared with ordinary bag, not only water and oil repellent properties, but in terms of dust, but also has anti-blocking properties and ease of removability, bag cleaning cycle life prolonged and extended through the gas flow is increased, it can be a lot of savings in energy and maintenance costs, but also increased production, anti-static dust bag in the general industrial dust concentration reaches a certain level (ie explosive limit), in case of electrostatic discharge spark ignition or external factors such as the polar easily lead to explosions and fires. In the dust removal system, the dust in the pipeline, as well as dust bag on the mutual friction between the collision, peeling, broken filter surface will cause dust and static electricity. When the filter surface with a certain amount of the charge can not be promptly released to go out, they will form a high-voltage spark discharge, which is likely to result in a dust explosion. I produced the anti-static needle punched filter felt, there are two: one is in the warp and needle felt fabric infiltration copper complexes known as striped antistatic conductive yarn; Another is uniformly mixed in the chemical fiber conductive said antistatic fiber blend. Anti-static needle punched filter felt authorities have been tested, and blast furnace gas in domestic coal mill, cement mill coal mill dust collection system and the actual working conditions to obtain the desired results, to provide users with considerable economic benefits , the user has a high rating.
