Degassing conductivity measurement system and method

Abstract

The invention discloses a degassing conductivity measurement system and method. A bottle cap is arranged at a top opening of a sampling bottle; the bottle cap is provided with a filter element; and anoutlet of the sampling bottle is communicated with an inlet of a first conductivity detector. A water sample at an outlet of the first conductivity detector is divided into two paths, wherein one path of water sample joins to an outlet of an acid adding device through a pipe and is communicated with an inlet of a first channel of a degassing membrane, an outlet of the first channel of the degassing membrane being communicated with a drainage pipe; and the other path of water sample is communicated with a water inlet of an electrodeionization device, a water outlet of the electrodeionization device being communicated with an inlet of a second channel of the degassing membrane. The outlet of the second channel of the degassing membrane is communicated with an inlet of a second conductivitydetector; an outlet of the second conductivity detector is communicated with an electrolytic water channel inlet of the electrodeionization device; and an electrolytic water channel outlet of the electrodeionization device is communicated with a drainage pipeline. The system and method can accurately realize off-line measurement of degassing conductivity of a pure water sample.

Description

technical field [0001] The invention relates to a degassed conductivity measurement system and method, in particular to a pure water conductivity measurement system and method. Background technique [0002] Conductivity is an important index to characterize the purity of water (steam) in power plants, but in practical applications, carbon dioxide in the air can easily enter the measurement system and affect the measurement. Therefore, when measuring the conductivity of pure water used in the electric power, electronics and pharmaceutical industries, in order to avoid The interference of carbon dioxide requires online measurement of the conductivity of the water sample. [0003] Defects of the existing technology: When measuring the conductivity of pure water, the interference of carbon dioxide is serious, and online measurement must be carried out, and whether the conductivity meter used for measurement is accurate or not needs to be compared with a higher-level instrument, ...
