How to choose a bag filter?

1. First understand the temperature of the flue gas. The filter bag is the core component of the bag filter. It is very important that the selected filter material can adapt to the temperature of the flue gas. If the temperature of the filter material exceeds the temperature of the flue gas too much, the cost of the high-temperature filter material is high, and the investment in equipment increases. If the normal use temperature of the filter material is lower than the temperature of the flue gas, it may cause the bag to burn and cause great economic loss. The filter material is divided into: normal temperature filter material below 130 °C, medium temperature filter material 130~180 °C, high temperature filter material 180~280 °C.
2. The second step is to understand the composition of the flue gas: this includes parameters such as dust content, specific gravity, particle size, viscosity, and moisture content of the flue gas. By understanding these methods, the dust cleaning method of the dust collector, the post-treatment method of the filter material, and the filtration wind speed are determined.
3. The third step is to understand the amount of flue gas that needs to be treated: the air volume of the precipitator is usually the working air volume plus the system air leakage coefficient (10%~15%).
Formula: S = Q / 60V gives the total filtration area.
S: total filtration area
Q: The system handles air volume
V: Filter the wind speed, first understand the temperature of the flue gas to be treated: the filter bag is the core component of the bag filter. It is very important that the selected filter material can adapt to the temperature of the flue gas. If the normal use temperature of the filter material exceeds the temperature of the flue gas, the investment in the equipment increases due to the high cost of the high-temperature filter material.
