Document Type and Number:
Japanese Patent JP3855072
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent damage to a heat exchanger caused by foreign matters and improve maintainability of the heat exchanger.
SOLUTION: A heat exchanger 10 is detachably installed at a side part internal wall of a pump suction water tank 11 and arranged in such a way that a heat exchanger tube 10A is parallel with the flow direction of water in the pump suction water tank 11. In the pump suction water tank 11, water flows from the left side to the right side in a figure, and a dust collector 12 is provided upstream of the heat exchanger 10, while a pump is provided downstream. The heat exchanger 10 is installed at the rear-side side part internal wall of the pump suction water tank, but similar heat exchangers are installed at a front-side side part internal wall and further at a bottom part internal wall. Piping 14 is connected to the heat exchanger tube 10A, and this piping 14 is connected to piping 16 on the ground side through a coupler 15. The piping 14 can be easily attached to and detached from the piping 16 by the coupler 15.
