Title: Method for charging sludge to filter press
Inventor: TOKUNAGA KIYOHIKO
IPC: B01D25/12
Filed: 1982-05-08
Abstract: PURPOSE:To dehydrate efficiently without damaging a filter plate, by controlling a pump so as to make a charging pressure a target one after attaining a prescribed charging pressure by keeping the number of revolutions of the pump constant. CONSTITUTION:Through a flowmeter 5 and an on-off valve 6, a filter press 7 is connected to the delivery side of a charging pump 3 of which suction side is connected to a flocculation-mixing tank 1 through an on-off valve 2. The pump 3 is controlled by a controller 9 basing on a detected value of a pressure detector 8 provided to a pipe line between the pump 3 and the filter press 7. Now the pump 3 is driven at the constant number of revolutions by opening the valves 2 and 6 to charge a sludge from the pump 3 to the filter press 7 through the flowmeter 5, and a charging pressure is detected by the detector 8. When the detected pressure reaches a prescribed one, the controller 9 starts to attain a target charging pressure by PID control and then continues the charging operation. A rise of the charging pressure is controlled by decreasing the number of revolutions of the pump 3 with the advance of sludge filtration, and the number of revolutions of the pump 3 is kept constant when it reaches the prescribed number of revolutions nearly at the finishing time of filtering operation, thus the dehydration is efficiently performed without causing the fluctuation of charging pressure.
