Abstract

The invention relates to an automatic continuous measurement method for steam-water sampling hydrogen conductivity, and belongs to the technical field of power generation. A first valve is connected with an inlet of a first cation exchange resin column, and a second valve is connected with an inlet of a second cation exchange resin column; an outlet of the first cation exchange resin column is connected with a third valve, and an outlet of the second cation exchange resin column is connected with an inlet of a fourth valve; an outlet of the first flow meter is connected with an inlet of the first conductivity tester, and an outlet of the second flow meter is connected with an inlet of the second conductivity tester; an outlet of the first conductivity tester and an outlet of the second conductivity tester are both connected with the water outlet. Synchronous monitoring of hydrogen conductivity and conductivity can be realized, effectiveness of hydrogen conductivity is automatically judged, automatic continuous measurement of hydrogen conductivity is realized, interruption of hydrogen conductivity monitoring and abnormity of monitoring data are avoided, prompting of failure of the cation exchange resin column is realized, and timely operation, maintenance and replacement are facilitated.

Description

technical field [0001] The invention relates to a method, in particular to an automatic and continuous measurement method for sampling hydrogen conductivity of soda water, which belongs to the technical field of power generation. Background technique [0002] With the development of boiler technology, there are more and more large-capacity and high-parameter boilers, and the requirements for soda quality are also getting higher and higher. The soda water sampling rack is an important tool for the supervision and analysis of soda water in thermal power plants. It can conduct real-time and online analysis of various steam and boiler water in thermal power plants. Among them, the hydrogen conductivity meter is the most online chemical instrument on the soda sampling rack, and plays an important role in the supervision of soda water in thermal power plants. [0003] At present, the steam and water sampling racks in thermal power plants all use the traditional online hydrogen me...
