Solving
Vacuum filter performance (G, t/s,sense of soda.) determine with the formula: GFdrn 60ω , 1000 Here F is the area of the filtering surface, m2; is the thickness of the bicarbonate sediment layer in the filter, m; - sediment density in the filter, kg/m3; – compression coefficient; n – drum rotation speed min–1; is the coefficient of soda release from bicarbonate; is the coefficient for standard soda (0.992). Removal of sediment from the field in one revolution of the drum: F= DL = 3.14 · 1.8 · 0.98 = 5.55 m2. The coefficient of compression of sediments is calculated based on the total thickness of the sediment layer and the thickness of the layer remaining in the fabric after cutting: d d' 40 5 0.875. d 40 The product filter works as follows: G5.55 0.04 1320 0.875 1 60 0.52 8.07 t/h. 1000 0.992 Download 33.51 Kb.
