Because the form of the bag filter and the type and characteristics of the filter material are different, there is a great difference in the filter wind speed, and once the processing air volume is determined, the filter area can be determined according to the filter wind speed. When calculating the processing gas of the bag filter, it is necessary to first determine the gas volume under working conditions, that is, the gas data actually passed through the bag type dedusting equipment should be determined based on the actual operation experience or testing data of the existing plant, if it is not necessary The data can be calculated according to the production process (about 20% to 40%).
The formula is: Q = Qs (273 + Tc) * 101.324 / (273 * Pa) * (1 + K) where Q – dust gas through the dust collector m3 / h; Qs – gas produced during the production process Quantity m3/h; Tc – temperature of the gas in the precipitator °C; Pa-atmospheric pressure, kPa; K-precipitator air leakage system. It should be noted that if the amount of gas produced during the production process is the amount of gas in the working state, the comparison of the type selection should be converted to the standard state.
