Generally, the adjustment range of differential speed should be increased or decreased by 1 each time to avoid excessive range. In short, there is a certain contradiction between processing capacity and processing effect. To improve the processing capacity, the differential ratio needs to be increased, but it may reduce the biscuit degree of mud; To improve the degree of mud biscuit, it is necessary to reduce the differential speed, thus reducing the processing capacity. Therefore, the on-site commissioning work is to find the best operating parameters under the conditions consistent with the on-site sludge properties, so as to achieve the dual goals of the highest equipment operating efficiency and the best treatment effect. This needs to rely on long-term actual commissioning experience and make timely adjustments according to changes.
At the same drum speed, the larger the length diameter ratio is, the greater the processing capacity is Centrifuge The longer the relative settling time inside the drum is, the lower the moisture content of the separated solid material is, and the better the separation effect is; On the contrary, the separation effect is worse.
The comprehensive adjustment principle of the operating condition of the centrifuge is to adjust the differential speed and another operating parameter (sludge flow or flocculant dosage) when one parameter (sludge flow or flocculant dosage) is fixed. During the specific operation, at the initial stage, according to the dosage of 6 grams of PAM per kilogram of dry sludge, on the premise of keeping the dosage of flocculant unchanged, by adjusting the rotation speed of the sludge screw pump, the sludge is fed according to the maximum flow, and the differential speed is gradually increased from low to high until the supernatant is completely clear. If the differential speed has been increased to more than 7r/min, but the content of suspended solids in the supernatant is still high, it means that the sludge inflow has exceeded the maximum dry solid load of the centrifuge. At this time, gradually reduce the sludge flow according to the gradient of 100%, 90%, 80%, 70%, 60%, 50%, 40% until a good supernatant appears. After the above adjustment, after the centrifuge runs stably, gradually reduce the dosage of flocculant until a good solid content of mud cake and supernatant can be obtained with the minimum dosage of PAM.
