Study on multi-parameter collaborative monitoring methods for hydrogen conductivity in water vapor degassing
摘要
Abstract
This paper proposes a multi-parameter collaborative monitoring system and method for degassed hydrogen conductivity based on the combination of double water membrane degassed method and electric regeneration ion exchange technology,which can quickly measure a number of key water quality indicators such as conductivity,hydrogen conductivity,degassed hydrogen conductivity and pH.It can make comprehensive evaluation of water quality,guide thermal equipment shutdown and startup.And it can adjust normal operating water conditions.It has a great significance for ensuring water vapor quality and thermal equipment corrosion,salt accumulation and scale formation.Double water membrane degassing technology is used to measure degassed hydrogen conductivity,which can effectively remove CO2 from water.On this basis,a method of calibration degassed hydrogen conductivity measured by standard solution is proposed,so that the accuracy of the measured value can be effectively evaluated.This method has been applied to typical gas combined cycle units and heating units for on-site supervision.It proves that the method has high measurement accuracy,can quickly and comprehensively evaluate water vapor quality,and it can assist in solving various technical problems on site.Therefore,it has strong popularization and application value.关键词
