叶轮切削与梯级加压海淡系统的通量分布

Flux distribution in seawater desalination system with cascade pressurization and impeller cutting

基于反渗透海水淡化系统的梯级加压模式,提出了以切削叶轮及增小叶轮技术实现特定系统通量分布的概念,从而可实现海水淡化系统沿程通量的可控递减分布或其它形式的通量分布.讨论了采用特定的叶轮切削量时,温度、浓度、通量、收率、污染程度等运行条件的变化对于通量分布及其它运行参数的影响.

Based on the cascade pressurization mode of reverse osmosis desalination system, the concept of flux distribution of specific systems with cutting impeller and adding small impeller technology is proposed, which can realize the controllable decrement or other forms of flux distribution along the course of seawater desalination system. The influence of the change of operating conditions such as temperature, concentration, flux, yield, and pollution on the flux distribution is discussed with specific cut amount of impeller.
