Among the flue gas that needs to be treated with pulse bags, some are high -temperature flue gas, such as high -temperature boiler flue gas and various ironmaking flue gas, and some industrial kiln flue gas. These high -temperature smoke and dust enters the pulse bag dust collector, and the filter bag of the pulse bag dust collector does not take any cooling measures, and the combustion phenomenon will occur and damage the pulse bag dust collector. So how to choose the filter bag of the pulse bag dust collector? Let's meet with the filter bag manufacturer!
(1) The filter bag of the pulse bag dust collector should be determined according to the temperature, water content, acidity, alkali, dust viscosity, concentration and grinding degree, size, etc.
(2) Generally speaking, when the water content is low and there is no acidic substance, the selection should be selected according to the temperature of the dust -containing gas. When the room temperature or 130 degrees Celsius, the polyester needle felt of 500 ~ 550g/m² is usually used. When the temperature is less than 250 degrees Celsius, you should choose a glass fiber needle felt or a 800g/m2 glass fiber needle felt.
(3) When the dust is large and the dust concentration is large, the waterproof oil -proof filter bag (or a exposed filter bag) should be used.
(4) When the dust -containing gas contains acid and alkali, and the temperature of the gas is less than or equal to 220 degrees Celsius, the Leiden needle felt. When the temperature of the gas is less than or equal to 280 degrees Celsius, please use the P84 needle felt, when the dust is dust, when the dust is dust When the gas is flammable and explosive gas, please use anti -static polyester needle felt. When the dust -containing gas contains the corresponding water and flammable and explosive gas, please use waterproof, oil -proof and anticrocating polyester needle thorns. felt.
Pulse bag dust collectors can handle large particles of dust. The pulse bag dust collector has high dust removal efficiency. The export dust concentration can meet national emissions standards, even lower than 10mg/m3. Bag materials, etc. determine the appropriate filtration wind speed. The resistance of the pulse bag dust collector is proportional to the fan power. This is an indicator directly related to the energy consumption of the fan, and it also involves the operating cost of the dust removal system. Factors are related, such as the structure of the device, the type of filtering materials, the nature of dust, dust removal method, filtering wind speed, gas temperature and humidity, etc. If any of them are problems, it will cause the pulse bag dust collector to rise, the pulse cloth bag will The resistance of the dust collector is generally controlled within the range of 1200 to 1500Pa, ensuring that the pulse bag dust collector can be quickly removed from the filter bag without damaging the filter bag.
