How to choose a high quality pulse bag filter

The bag filter should be selected according to factors such as dust filtration area, material characteristics, filtration wind speed, and material temperature. As we all know, there are many specifications and models of the pulse bag filter, which are applied in different industries according to the different characteristics and performance of the industry. How do we choose a high quality pulse bag filter?

First introduce the pulse bag filter, understand its contents to better choose the pulse bag filter.

Filtration speed is a key factor in the selection of pulse bag filter. It should be determined according to the nature of dust or dust, application, dust particle size, viscosity, gas temperature, moisture content, dust concentration and different filter materials. When the dust particle size is fine, the temperature and humidity are high, the concentration is large, and the viscosity is relatively high. Such as ≤ 1m / min; otherwise, the optional high value, generally should not exceed 1.5m / min. For the dust particle size is large, normal temperature, dry, non-sticky, and the concentration is extremely low, you can choose 1.5 ~ 2m / min. When the filtration speed is selected, it should be calculated that the net filtration wind speed when reducing the filtration area of one chamber (when cleaning) should not exceed the above values.

The filter material should be considered according to the temperature, water content, acidity, alkalinity, dust viscosity, concentration and sharpness of the dust-containing gas. Generally, when the water content is small and there is no acidity, it is selected according to the temperature of the dust-containing gas. When the temperature is normal or ≤130 °C, the polyester needle felt of 500-550 g/m2 is commonly used. <250°C, use aramid Nomex needle felt or 800g/m2 glass fiber needle felt or 800g/m2 weft double fiberglass fabric or flumex [FMS] high temperature filter material (fluorine gas can not be used) Glass fiber material). When the water content is large and the dust concentration is large, it is recommended to use waterproof and oil-proof filter material (or anti-condensation filter material) or film filter material (the base cloth should be waterproof felt needle felt). When the dust-containing gas contains acid and alkali and the gas temperature is ≤190 °C, Ryton (polyphenylene sulfide) needle felt is often used. P84 (polyimide) needle felt is used when the gas temperature is ≤240 °C and the acid and alkali resistance is not too high. When the dust-containing gas is a flammable and explosive gas, the anti-static rayon needle felt is used. When the dust-containing gas has both certain moisture and flammable and explosive gas, it is waterproof, oil-proof and anti-static (three-proof). Polyester needle felt.
