Abstract
PURPOSE: To perform dehydrating treatment of sludge while thawing by the procedure in which frozen sludge is thawed and at the same time pressurized by supplying a heating medium into the space between diaphragm surrounding filter body and casing.
CONSTITUTION: The unfrozen sludge filled up in the first container 1 si frozen by passage of a refrigerating medium through the pathway 5, and after the completion of freezing, the refrigerating medium present in the pathway 5 is replaced with a heating medium and the heating medium is flowed for a given hour to remove frozen sludge from the wall of the container 1. Then, fresh unfrozen sludge is forced into the container 1 by pressure to push a columnar frozen sludge out of the container 1 and the columnar frozen sludge is sent to the filter cloth body 8 and then stopped by the stopper 13. Then, under a condition that a certain amount of frozen sludge remains in the container 1, between the inlet 15 and the casing 11 and the outlet 16 is heated to a fixed temperature and also a pressurized heating medium is circulated to thraw the frozen sludge. And, after thawing and dehydration are finished, the supply of the heating medium is stopped, the cover 12 is opened, the frozen sludge in the container 1 is peeled off, fresh sludge is forced into the container 1 by pressure 7, and dehydrated sludge cake in the filter cloth body 8 is discharged through frozen sludge.
