High-efficiency filter air volume calculation method
High-efficiency filter air volume calculation methodMethod 1: the premise has a partition high-efficiency filter air volume that is generally based on high-efficiency filter wind speed and size to determine the size of the general high-efficiency filter out of the wind speed in the 0.3-0.6M/S, you can take the intermediate value of 0.45, for example, we all know that the 1000 air volume of high-efficiency filter size is: 484 * 484 * 220 converted to come out of the method is very simple, but not precise enough! This method is very simple, but not precise enough, and there are more accurate calculation methods below.Method 2: the national standard 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 split for 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, 280 for 1 meter, the effective width, 280 for 1 meter, the effective width, the effective width, the effective width, the effective width, the effective width, the effective width of 280 for 1 meter. Effective width, 280 for 1 meter of filter paper folded double layer, 0.2 for the actual height of the filter paper, 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, the initial resistance of the filter paper in 200PA. Conclusion: high-efficiency filter air volume, a 900 * 600 * 370 filter, 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 number of folded filter paper for the standard filter 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 This is a standard high-efficiency filter with a partition calculation method. |
