Title: Method for operating centrifugal clarification machine
Inventor: HATA KENJI
IPC: G21C19/46
Filed: 1989-02-10
Abstract: PURPOSE:To reduce the loss of effective components in rinsing operation by stopping the rotation of a bowl and collecting clarified liquid while leaving a sludge deposit layer, and rinsing the sludge and collecting effective components. CONSTITUTION:When solution is supplied into the bowl 1c in rotation from a liquid feed nozzle 1e, sludge in the liquid is caught by the internal wall of the bowl 1c. The rotation of the bowl 1c is stopped temporarily and clarified liquid pooled in the bowl 1c is collected in a recovery tank 4 through the discharge opening of a casing 1d, but the deposit layer of sludge is left on a wall surface. Then while the bowl 1c is rotated at a rated rotating speed, rinsing liquid is jetted from a nozzle 1f to separate the sludge deposit layer. Consequently, U and Pu staying among sludge particles by impregnation are substituted to collect effective components. Then when the rotating speed is increased, sludge is collected by the internal wall again. This operation is repeated several times, then the solution is switched to cleaning liquid, and a flow passage switching device 6 is switched to a sludge recovery tank 5; and the inside of the bowl 1c is cleaned and the sludge is collected 5.
