Bag filters

The pollution problem of smoke and dust emissions is a problem that needs to be solved in the power, cement, iron and steel, metallurgy and chemical industries. In the process of industrial fume and exhaust gas treatment, the pulsed bag filter was patented in 1958 to ensure the efficient, stable and micro-emission of flue gas. Is an ideal high efficiency dust removal equipment.

Whether the bag dust collector can be used successfully in industrial dust control, the first one is whether the filter material is selected properly. When the bag dust collector of the waste gas treatment equipment is manufactured, the temperature of flue gas, the emission standard and the chemical nature of the flue gas must be considered to select the more suitable filter. Material bag to ensure the effect of dust removal and equipment life. Today we introduce hybrid fiber filters:

Fibrous materials used in the manufacture of filter media have their own advantages and disadvantages. In order to enhance their strengths and avoid shortcomings, two or more fiber materials can be mixed and processed into filter media, which is called mixed fiber filter media. .

Exhaust gas treatment equipment bag filter mixed fiber filter, the use of glass fiber and high temperature resistant synthetic fiber composite needle acupuncture applications. Mixtures made of glass fiber and aramid fiber are more suitable for blast furnace gas purification, but also for the secondary flue gas purification of electric furnaces and converters. This kind of composite felt reduces the defect of imperfect folding of pure glass fiber mat through the mixing of glass fiber and aramid, or improves the folding resistance of glass fiber. For pure aramid fiber mat, it is made by mixing with glass fiber. The resulting composite felt reduces the cost of the aramid felt.

The exhaust gas treatment equipment uses a composite felt made of glass fiber mixed with PPS fiber to be used for the purification of boiler flue gas. Here is mainly to consider the PPS's excellent acid and alkali corrosion resistance of the fiber, this kind of composite mat can meet the power plant's coal-fired boiler flue gas purification requirements, but also lower than the cost of pure PPS fiber filter material.

Exhaust gas treatment equipment using PPS and P84 fiber blended PPS needle felt filter material using P84 fiber temperature performance and better cohesion properties than PPS is good, reduce high temperature dust and hot particles on the filter surface damage.

Glass fiber cloths made of glass fiber yarns and Teflon yarns can also be included in this range.

After the industrial dust exhaust gas treatment dust enters the bag filter, the surface of the filter bag intercepts and deposits dust, the resistance of the filter bag will increase, and the air permeability will decrease. At this time, the powder layer will be peeled off and settled by the dust removal device, and the resistance of the filter bag will be restored. Bag filter is a working process of collecting dust and cleaning periodically. The importance of filter bags is very important.
