Title: Method and device for back washing
Inventor: REO RAIAN
IPC: B01D29/62
Filed: 1991-10-15
Abstract: PURPOSE: To generate a propulsive force to rapidly move filter surfaces outward in the radial direction to backwash liquid by feeding gas into a plenum compartment and a filter compartment, forming a pressurized state therein, then rapidly dropping the pressure in the filter compartment. CONSTITUTION: When a valve 88 is opened while valves 75 and 77 are held open, a prescribed volume of the backwash liquid is fed above a tube sheet 66 into a plenum compartment 64 through a pipeline 87 down to a depth shown by a line 86. A pressurized gas is then fed into the filter compartment 62, then into the plenum compartment 64 by closing the valves 75, 75, 88 and opening valves 98, 96. When the valve 98 is closed and the valve 77 and a control valve 106 are rapidly opened, the pressure in the filter compartment 62 drops below the pressure of the plenum compartment 64 and a pressure difference is generated during the time, a propulsive force for moving the prescribed volume of the backwash liquid is generated and the piston-like flow of the backwash liquid from above the tube sheet 66 is surged downward in the central parts of the respective filter elements 68.  Then, the instantaneously high surges of the flow in the radial direction are generated on the filter surfaces of the respective filter elements 68.
