Abstract

PURPOSE: To make better the fluidity of sludge and hasten the freezing of the sludge by supplying a liquid substance of a higher fluidity than sludge to unfrozen sludge upheaved by its volumetric expansion by freezing between heat exchangers.
CONSTITUTION: When flowing a cooling brine into the heat exchangers 2a and 2b, the unfrozen sludge 4 is upheaved at the center of the frozen portion 5 between both heat exhangers, and then as the upheave exceeds, a liquid substnace of a higher fluidity than the sludge, e.g., water, is added in a fixed amount to the upheaved sludge 4 protion, whereby the fluidity of the sludge 4 is made better and the sludge extends in the form of the mixed sludge 7 into between the heat exchangers 2a and 2b and thus the contact area between the heat exchangers 2a and 2b is increased freezing time is shortened. Also, the liquid substance is jetted onto the sludge 4 at a fixed pressure to make better the mixing of the sludge and water and the extention of the sludge for enhancing expected effects.
