METHOD OF WASHING ROTATING TUBE OF HORIZONTAL TYPE TUBULAR CENTRIFUGAL SEPARATOR

摘要

Removal of sediment from a centrifugal separator has hitherto been done by hand, which adds to the cleaning cost. For the same reason large centrifugal separators have involved difficulties in independent operation. This invention provides a cleaning method for removing sediment from the inner wall of the rotary drum of a horizontal drum-type centrifugal separator that rotates with trunnions at both ends supported by bearings, which comprises charging a plurality of solid cleaning medium pieces into the rotary drum, supplying a cleaning liquid to the rotary drum, rotating the drum, and discharging the sediment together with the cleaning liquid. The solid cleaning medium is charged into the rotary drum either before centrifugal separation or at the time of cleaning after centrifugal separation. <IMAGE>
