Is the differential pressure method for calculating air volume suitable for calculating process air volume?
Thread Content
Can the differential pressure method for calculating air leakage be applied to the calculation of process air flow? For example: In dryers, the air volume X can be calculated to determine how much water can be removed; the pressure difference method is used to calculate the air leakage volume Y of the dryer, which serves as the process air volume. Is the pressure difference method feasible? Or take the maximum of X and Y?
Do you mean by the air leakage pressure difference the pressure difference between the inlet air pressure of the dryer and the outlet air pressure of the dryer? . . Normally, all parameters of the wind are determined through process calculations, and then the equipment parameters are determined in sequence. If that’s what you mean by the so-called air leakage rate, then the airflow amount calculated using this value should be consistent with the airflow amount determined through your process calculations. Otherwise, it’s either due to an error in the calculation of the equipment parameters, or it’s because the equipment pressure loss selected during the calculation based on pressure differences is incorrect. If you need to calculate the required air volume, it is more accurate to do so based on the process parameters, as it is difficult to calculate or estimate the pressure loss inside the actual equipment.
