A COOLING WATER MULTI-LAYER WATER PIPE FOR ALLEVIATING FORMATION AT INTAKE AND OUTFALL OF POWER PLANT

摘要

A multi-layer water pipe for removing coolant bubbles in an intake/outtake water ways of a power plant is provided to prevent air from being mixed with the coolant by allowing intake water to flow through a main water way and a multi-layer water pipe. A multi-layer water pipe for removing coolant bubbles in intake/ outtake water ways of a power plant comprises a main water way tube(5) and a multi-layer tube(6) that are disposed in parallel to each other between an outlet(3a) of an intake tube(3) and an intake water tank(4). A sub-water tank(7) is formed between the outlet of the intake tube and an inlet(6a) of the multi-layer tube. The outlet of the intake tube is connected with the inlet of the multi-layer and the main water way tube. The inlet of the multi-layer tube has an inverse U-type.
