反渗透海水淡化工程能量回收设计比选

Comparison and Selection of Energy Recovery Design for Reverse Osmosis Seawater Desalination Project

高压系统是反渗透淡化工程的主要耗能单元,文章通过能耗计算,分析大型海水淡化工程中普遍应用的两种形式的能量回收装置的电耗情况,求证采用不同形式能量回收装置时,海水淡化系统吨水电耗随产水规模的变化趋势,为大规模海水淡化工程高压系统提供设计参考。

High pressure system is the main energy consuming unit of the reverse osmosis desalination project.Through specific energy consumption calculation,this article analyzed the power consumption of two forms of energy recovery devices commonly used in large-scale seawater desalination projects,and verified the change trend of power consumption per ton of water of seawater desalination system with water production scale when different forms of energy recovery devices are used.It provided a design reference for the high-pressure system of large-scale seawater desalination project.
