离子膜烧碱是利用盐水电解来制碱,能耗很大,为了提高电流效率以达到节能增效的目的,必须对盐水及电解液的质量进行控制,控制的好坏关键在于仪表的测量是否准确、可靠。如何选择合适的能满足现场要求的仪表显得尤为重要,根据工艺介质温度高、腐蚀性强等特点,详细说明了分析仪表在选型、安装、调试及使用等各个环节中应注意的问题。
Ion membrane caustic soda is the use of salt water electrolysis to alkali, energy consumption is great, in order to improve the current efficiency in order to achieve energy efficiency, the quality of the brine and electrolyte must be controlled, the key is good or bad control of the measurement instrument is accurate ,reliable. It is very important to choose suitable instruments that can meet the requirements of the site. According to the characteristics of high temperature and strong corrosivity of process media, the problems that should be noticed in the selection, installation, commissioning and use of analytical instruments are described in detail.
