Application of acrylic dust removal cloth bag

Time : 2023-06-28 Hits : 6

The application of acrylic dust bag, acrylic dust bag will not hydrolyze When the temperature is lower than 125 ℃, it has good resistance to organic solvents, oxidants, organic mechanisms and organic acids. Polyacrylonitrile homopolymerization is not produced from polycondensation polymers, and is often used to replace fibers with hydrolysis problems, that is, to replace polyester at low temperature, humidity and chemical corrosion. The copolymer of acrylonitrile is not resistant to hydrolysis, so it can not be used to replace homopolymer in filtration. It can be used in waste incineration, asphalt, coal mill, power plant and other flue gas dust collection in low temperature, high chemical corrosion and humid occasions. Acrylic needled felt is chemically called polyacrylonitrile. It is used as raw material to make felt by needling method, and then through special water and oil repellent treatment, acrylic medium temperature anti hydrolysis needled filter felt is obtained. Needled felt is based on acrylic woven fabric to enhance the vertical and horizontal strength. It has excellent chemical resistance and hydrolysis resistance. It is widely used in garbage incineration, asphalt, spray dryer, coal mill, power plant and other flue gas dust filtration. Acrylic dust removal cloth bag has the following characteristics: 1. The continuous working temperature is 130 ℃, and the instantaneous working temperature does not exceed 140 ℃; 2. Good acid and alkaline resistance, pH value between 3-11; 3. The relative humidity is less than 30%, pay attention to oxidation. Acrylic filter bag: when the temperature is lower than 125 ℃, it has good resistance to organic solvents, oxidants, inorganic and organic acids. Acrylic is not a self condensation polymer, which is often used to replace fibers with hydrolysis problems, that is, it is used in low temperature, humidity and chemical corrosion. The medium temperature acrylic dust removal cloth bag is made of homopolyacrylonitrile fiber, and its price is higher than that of ordinary normal temperature dust removal cloth bag, but it is mostly used in ordinary bag dust collectors. The long service life of bag filter will cause the rise of flue gas temperature in work, which is fatal to ordinary dust removal bag. The medium temperature dust removal cloth bag is a good choice. Acrylic needled felt is made of material, and proper post-treatment is the advantage of acrylic needled felt dust removal cloth bag. The air permeability of medium temperature acrylic needle felt dust removal cloth bag is generally maintained at 14m3 / m2 • min, but the retroperitoneal acrylic needle felt will weaken the air permeability, and acrylic can achieve good dust removal effect in a certain working environment. The use of acrylic needled felt lies in the selection of acrylic needled felt products. All dust removal cloth bag products are not universal, we should understand. Acrylic needled felt is a filter material with good dust removal effect in the field of normal temperature dust removal. This product gives full play to the characteristics of acid-base resistance and hydrolysis value in normal temperature filter material, and it is an indispensable kind of normal temperature dust removal cloth bag. Acrylic needle felt is one of the commonly used varieties in medium temperature dust removal cloth bags. The average service temperature is 125 ℃, and the instantaneous working temperature is 140 ℃. It is used for dust collection of waste incineration, asphalt, dryer, coal mill, power plant and other flue gases. The dust removal cloth bag is the heart of the operation of the bag type dust collector. Usually, the cylindrical pulse filter bag is suspended vertically in the dust collector, and the dusty gas enters the dust collector from the air inlet, passes through the deflector of the ash bucket, so that part of the large particle dust in the gas is separated by the inertia force, and directly falls into the ash bucket. The dusty gas enters the filter bag filtration area of the box, and most of the dust is trapped on the outer surface of the filter bag, The clean gas enters the filter bag through the filter material, and the purified gas enters the upper box through the filter bag mouth, and then is discharged from the air outlet. The cage inside the filter bag is used to support the filter bag, prevent the collapse of the filter bag, and it is conducive to the removal and redistribution of dust cake. Prev:
