填海工程影响下的电厂冷却水工程布置数值模拟研究

Numerical simulation on cooling water project over an artificial land engineering

随着大亚湾北岸大规模填海造地工程的实施,将影响潮流流态,给拟建于该开发区的惠州LNG电厂循环冷却水工程优化布置带来困难。针对这种情况,利用数学模型对现状海域流场进行了验证计算;对规划岸线下的流场变化情况进行了模拟;对电厂温排水的运行扩散规律进行了模拟,在考虑取水温度、经济性、环保性的基础上,提出了优化布置方案。该方案较传统方法思路更优化、观点更符合环保要求,更具有前瞻性,为类似工程的设计、研究提供了有益的经验。

Large scale of artificial land engineering will be performed in the north coast of Daya Bay and Huizhou LNG fire plant will be constructed.The sea water nearby will serve as the cooling water.The artificial land engineering will impact the flow pattern of near sea,and bring out some difficulties to the cooling water engineering.Verification calculation of flow velocity and tide of the sea under the present coastal line has been performed by mathematics model.The variation of flow in near sea under the programming coastal line and the diffusion rule of warm water has been simulated.An appropriate proposal of the cooling water engineering has been put forward considering the intaking temperature,economic property and the environment.Compared with the traditional method,consideration is an important progress.
