Abstract

PURPOSE: To effectively utilize energy by enhancing the dehydrating property of sludge making part of heat on the high temperature side of refrigerator absorb into sludge at heat exchanger provided at a freezing and thawing sludge dehydrator.
CONSTITUTION: Sludge is sent to the freezing portion through the leading-in pipe 1 for freezing, then sent to the thawing portion 3 for thawing, then sent to the dehydration portion 4 for dehydration, and lastly discharged through the outlet 5 for the cake and through the exhaust port 6 for the separated liquid. In this case, the inside of the dehydrating portion 4 is provided with the sludge heat exchanger 16 into which part of a high-temperature medium from the compressor 7 is introduced, and its heat quantity is made to absorb in sludge in order to lower the moisture content of dehydrated sludge.
