The filter cloth is a filter medium made of natural fibers or synthetic fibers. Including metal mesh or filter. Mainly used in air filtration and removal of dust, dust collection powder to purify the air, protect the environment in smelters, chemical plants, sugar, dyes, medicine, food and other industries.
Synthetic fibers are mainly polypropylene, polyester, nylon, vinylon, etc., of which the most commonly used polyester and polypropylene to solid-liquid separation, while the nylon is widely used in the coal preparation plant, because of its excellent wear resistance.
The new high efficiency filter cloth is mainly used in air filtration and dust removal, dust collection powder, to purify the air, protect the environment, in the smelter, chemical plants, sugar, dyes, medicine, food and other industrial applications.
Polyester, polypropylene, nylon, cotton and other materials of the filter cloth, screen, is widely used in pharmaceutical, chemical, dyes, steel, construction, metallurgical iron, chemicals, ceramics, cement, geology, minerals and other industries.
Special filter cloth: aramid, PTFE, PVDF, etc., the use of high temperature
Ironmaking plants, steel mills, ferroalloy plants, refractory plants, foundries, power plants and other flue gas treatment dust removal system. Waste incinerator, 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 metals smelting flue gas filtration, fine material recovery, liquid, solid separation. Chemical, coke, carbon black, dyes, pharmaceuticals, plastics and other fields of liquid-solid separation and recovery of fine materials. Mining, grain processing, flour, electronics industry, wood processing and other dust control and purification collection.
Advantages and disadvantages
Close to zero emissions, to achieve the most stringent environmental standards.
Good cleaning, can provide a higher ventilation, or can reduce the pressure.
Filter bag life extension, the reduction in the number of clean-up, so that equipment maintenance costs.
A higher air-to-cloth ratio can be designed with a smaller dust collector, reducing the energy consumption when the pressure drop is reduced.
Dust bag from the temperature can be divided into three categories, such as polyester bags at home temperature, such as polyester needle felt bag, anti-static dust bag, easy to clean dust bag, the temperature, such as polyester coated needle felt bag, three dust bag, Oil needle felt, high temperature category such as the United States Tate dust bag, fluoride cloth bags, glass needle felt filter bag, PPS acid bag, etc. Select dust bag should be based on gas
Body temperature, humidity and chemical properties; particle size, weight, shape, dust concentration filtration rate, cleaning methods, emission concentration and bag filter system and other factors.
Under normal circumstances, the pulse of the bag-type dust filter used needle felt, sub-room anti-blown bag filter or mechanical vibration bag filter selection of woven fabrics, such as high temperature conditions need to be acid and alkali Can choose high temperature class such as film Fumei Si, etc., choose dust bag to consider a lot of factors.
