上海CJ电厂温排水试验研究

The research for the thermal drainage test of Shanghai CJ power plant

本文主要根据冷却水物理模型试验关键相似条件,对于上海CJ电厂一、二、三期取排水工程冷却水物理模型进行了设计。详细介绍了对典型水文条件下的温差水流实验,测得了表层温度分布场以及取水口取水温升。结果表明,该模型较好地复演了原体水流流态,为减轻温排水相互影响程度及对环境影响的评价提供了科学的依据,并为各期循环水取排水工程安全、可靠、经济的运行提供了保证。

This paper introduces the surface temperature distribution and temperature rising after taking out water from outlet through temperature difference flow test under typical hydrology condition,according to the design of coollng water physics model of the water supply and drainage project on phase 1, 2 and 3 in Shanghai power plant. The test result indicates that the model is better imitating the original flow, and provides the reference for reducing thermal drainage effluence one another and to the environment, and guarantees the run of safety, credibility and economy in the recycle water taken in and drainage on each phase.
