反渗透海水淡化系统仪表选型分析

The Analysis of Instrument Selection in Reverse Osmosis Desalination Systems

要科学合理地了解反渗透海水淡化系统的运行状况,离不开各类监测仪表的支持。本文首先介绍反渗透海水淡化系统的基本工艺流程,接着阐述了为实现对运行状况的监控,相应仪表应具备的基本功能,最后分析了反渗透海水淡化系统中常用的监测仪表选型原则,包括温度、压力、流量以及液位等系统运行过程参数监测仪表,以及电导率仪、浊度计、p H计等水质参数监测仪表,可为反渗透海水淡化工程中仪表选型提供参考。

With the support of monitoring instruments, we are able to know the operational state of reverse osmosis desalination systems scientifically and reasonably. This paper introduces the basic process of reverse osmosis desalination systems, then elaborates what functions the instruments should have to monitor the operational status. On this basis, it analyzes the selection principles of monitoring instruments used in reverse osmosis desalination systems, including monitoring process operating parameters like temperature, pressure, flow, level and so on, as well as monitoring water quality parameters, such as conductivity, turbidity, pH, etc. It could provide reference for instrument selection in reverse osmosis desalination projects.
