Filter Cloth Classification

Filter cloth is a filtering medium made of natural fibers or synthetic fibers. Include metal mesh or mesh. It mainly applies to air filtration and dust removal, dust collecting powder, to purify air, protect environment, in smelting plant, chemical plant, sugar, dye, medicine, food and other industries.

apply

The flue gas treatment and dust removal system of iron and steel mill, steel mill, ferroalloy factory, fireproof factory, foundry and power plant etc. Garbage incinerators, coal-fired boilers, fluidized bed boilers and other smoke filters. Asphalt concrete mixing, building materials, cement ceramics, lime, gypsum and other production places. Aluminum electrolysis, lead, tin, zinc, copper and other rare metal smelting flue gas filtration, micromaterial recovery, liquid, solid separation. Chemical, coke, carbon black, dye, pharmaceutical, plastic and other fields of liquid solid separation and micromaterial recovery. Mining, grain processing, flour, electronic industry, wood processing and other dust treatment and purification collection

Merits and demerits

Close to zero emissions can meet the most stringent environmental standards.

Good ash quality, can provide higher ventilation volume, or can reduce pressure difference.

Prolong the life of filter bag, reduce the number of cleaning, make equipment maintenance cost lower.

Higher air cloth ratio can be designed with smaller dust remover and lower energy consumption.

Dust bag from temperature on roughly divided into 3 groups, normal temperature such as polyester fiber needled felt bag, anti-static dust bag, Yi Qing ash dust bag and so on, the medium temperature such as polyester coated needled felt bag, three anti dust bag, waterproof and oil proof needled felt, high temperature such as beauty, dust bag, fluorine beautiful cloth, glass fiber needled felt filter bag, PPS and alkali bag etc. Choose dust bag should be according to the gas

Temperature, humidity and chemical properties of body; Particle size, weight, shape, filter speed of dust concentration, clean ash method, discharge concentration and the working system of bag filter.

In general, the pulse jet bag dust collector choose needled felt, chamber blow or mechanical shaking bag filter bag filter machine weaving. Such as working conditions as high temperature resistance to acid and alkali and moisture can choose, such as high class effect of fluorine mae choose dust bag there are many factors to consider.

classification

1. The cross section of the filter bag is divided into: flat bag (trapezoid and flat) and round bag (cylindrical).

2. According to the way in and out of the wind, the wind of the wind and the wind in the wind and the straight flow (confined to the flat bag).

3. The filter mode of the filter bag is divided into: external and internal filtration.

4, according to the temperature of dust filter bag bear ability is divided into: high temperature, medium temperature, room temperature type 5, application field applications: iron, steel, iron alloy factory, refractory factory, foundry, power plants, cement plants, chemical plants, food processing plants, carbon black plant, aluminium plant, etc

(1) class at low temperature, suitable for raw meal grinding, cement mill, library and other local dust at the bottom point of bag filter is used, and used in under the condition of high moisture content still need to adopt oil-repellent waterproof treatment on the surface to surface treatment;

(2), high temperature, suitable for shaft kiln cement and rotary kiln preheater, cooling machine, dryer, etc. The high temperature of waste gas treatment of bag filter, and is used in high temperature, high humidity content under the condition of still need to use oil-repellent waterproof treatment on the surface to surface treatment; Material non-woven fabric applicable scope vacuum cleaner, filter pot, fan, air purifier, baking paint room, water purifier
