Problems solved by technology

[0004] However, this traditional hydrogen conductivity meter that uses ion exchange columns to remove or convert cations is prone to waste liquid or solid waste during the measurement process, and when the resin fails, the operator needs to regenerate or replace the resin regularly, which increases maintenance personnel.

Embodiment Construction

[0026] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the drawings. In the following description, the same reference numerals are given to the same components, and repeated descriptions are omitted. In addition, the drawings are only schematic diagrams, and the ratio of dimensions between components, the shape of components, and the like may be different from the actual ones.

[0027] Hydrogen conductivity is the most critical indicator to characterize the purity of water vapor and the total amount of anions in a power plant. GB / T12145-2016 "Water Vapor Quality Standards for Thermal Power Generation Units and Steam Power Equipment" stipulates that hydrogen conductivity is a key indicator for thermal equipment to prevent corrosion and scale. It is the indicator with the largest number of monitors among the water vapor control indicators of power plants. Once the hydrogen conductivity measurement is inaccurate, it cann...

Abstract

The invention discloses an electric regenerative system for measuring conductivity of water vapor hydrogen. The system comprises a power supply device, an electric regeneration cation exchange device connected with the power supply device, a conductivity measuring device, and a water sample cutoff detection device. In a power supply state of the power supply device, a to-be-detected water sample flowing in from a water sample inlet replaces cations in the electric regeneration cation exchange device, the to-be-detected water sample enters a conductivity cell through a water sample outlet and is subjected to conductivity measurement by a conductivity meter, and the water sample flowing out of the conductivity cell enters the regeneration cation exchange device again through the regeneration inlet to be electrolyzed; hydrogen ions are generated; the resin in the regeneration cation exchange device is regenerated through the generated hydrogen ions, and finally, the water sample is discharged through a regeneration outlet. Under the condition, the accuracy of measuring the conductivity of the hydrogen in the water vapor can be improved, the method has important significance for realizing complete continuous monitoring, and the field labor cost and the equipment maintenance cost can be saved.

Description

technical field [0001] The present disclosure generally relates to an electrically regenerative system for measuring the hydrogen conductivity of water vapor. Background technique [0002] The purpose of monitoring the chemical conductivity instrument in the power plant is to prevent or slow down scaling and corrosion in the thermal system and to monitor the operating conditions of the water treatment system. Through the effective measurement of the salt content of the system water quality, the operator can be well guided to make reasonable adjustments and controls. All kinds of water and steam pollution can reduce boiler four-tube blasting and water tank pollution. [0003] Hydrogen conductivity is an important parameter in the chemical supervision of power plants. It is usually the conductivity measured after water vapor and water samples are treated with cation exchange resins. It is used to characterize the anion content in water vapor and water samples. It is an importa...
