Calculation method of air volume of high efficiency filter with partition
Calculation method of air volume of high efficiency filter with partitionFirst, the first calculation method of the air volume of the high-efficiency filter with a partition: a 484 * 484 * 220 high-efficiency filter to calculate the rated air volume is 1000M3 / H, the initial resistance in 200PA, the number of filter paper splitting 28 fold / 10CM, the effective area of the filter paper calculation: 0.475 * 0.475 * 280 * 0.2 * 2 = 25.27 square meters, of which. 0.475 for the effective length of the filter paper, 0.475 for the effective width of the filter paper, 280 for the number of 1 meter of filter paper folding, 0.2 for the actual height of the filter paper, 2 for the double layer, the filter paper section wind speed = 1000/3600/25.27 = 0.011 m / s, that is to say, when passing through the cross-section of the filter paper wind speed of 0.011 m / s when the filter paper in the initial resistance of 200PA.Second, the filter air volume, a 900 * 600 * 370 filters 0.88 * 0.58 * 280 * 0.35 * 2 * 0.011 * 3600 = 3961m3 / h, of which 0.88 for the effective length of the filter paper, 0.58 for the effective width of the filter paper, 280 for the standard filter paper folding number of 1 meter, 0.35 for the actual height of the filter paper, 2 for the double layer. 0.011 for the filter paper section wind speed, 3600 for an hour is equal to 3600 seconds which is a standard high-efficiency filter with a partition air volume calculation method! According to the high-efficiency filter wind speed and size to determine the air volume, in general, we use high-efficiency filters, with rated wind speed between 0.3-0.6M/S, we can take the middle value of 0.45, to give a simple example, 1000 air volume of high-efficiency filters size is: 484*484*220, only need to be converted to derive the air volume, these two are our common! These two are our common methods of calculating the air volume of high-efficiency filters. |
