STEAM HEAT TREATMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To prevent the leakage of cooling water from a heat exchanger in a drain pipe.

SOLUTION: A steam heat treatment apparatus includes: a treatment tank for storing an object to be treated; a steam supplying means for supplying steam to the treatment tank; a pressure reducing means for carrying out pressure reduction of the inside of the treatment tank via a pressure reduction pipe; the heat exchanger for condensing the steam flowing in the pressure reduction pipe; and a blocking means for closing the pressure reduction pipe between the treatment tank and the heat exchanger when the inside of the treatment tank is heated by the steam supplying means.
