CLEANING METHOD OF A HEAT EXCHANGE PIPE AND COLLECTING APPARATUS FOR COLLECTING A PRECIPITATE FROM THE HEAT EXCHANGE PIPE

摘要

PURPOSE: A cleaning method of a heat exchange pipe and collecting apparatus for collecting a precipitate from the heat exchange pipe is provided, which cleans a heat exchange pipe of a heat exchanger of a nuclear equipment. CONSTITUTION: The collecting apparatus for collecting a precipitate from the heat exchange pipe comprises: a collecting chamber (26) having an inlet (28); a heat exchanger (2) to be guided through a pipe bottom (8), wherein the collecting chamber (26) is installed at the pipe bottom (8) or a lower region of the pipe bottom (8) and the inlet (28) of the collecting chamber (26) has a plurality of terminal portions (14, 14A, 16, 16A) of the heat exchanger (2), and the collecting chamber (26) is formed as a funnel and is sealed to the peripheral after fixing. Thereby, it is possible to perfectly remove the precipitate from the heat exchanger.
