热力压缩低温多效海水淡化特点及控制技术

Technological Characteristics and Control of Thermo-vapor Compressor Low Temperature Multi-effect Distillation Seawater Desalination Process

结合热力压缩低温多效海水淡化技术在神华河北国华黄骅发电厂的应用,介绍了采用该技术海淡设备的运行情况与海水淡化工艺流程,该工艺具有对海水的预处理较为简单、出水水质优良等技术特点,并对海淡设备的运行压力、温度、液位等关键性控制参数,进行了技术分析,提出了防止设备结垢与腐蚀的措施。

With the field application of thermo-vapor compressor low temperature multi-effect distillation （TVC-MED） in Shenhua Hebei Guohua Cangdong Power Generation Co. , Ltd, the components and technological process of TVC- MED is illustrated. The technological characteristics such as simple pretreatment, high quality product water, and so on, have been described in the paper. The key technological control of operating parameters of pressure, temperature, liquid level has also been analyzed. Preventive measures have been put forward so as to avoid equipment scaling and corrosion in the end.
