Description

technical field [0001] The invention belongs to the hydrogen conductivity measurement technology of a power plant, in particular to a hydrogen conductivity continuous on-line measurement device. Background technique [0002] Hydrogen conductivity is one of the core monitoring parameters of the water-gas system of a power plant. Measuring hydrogen conductivity can directly and sensitively reflect the total amount of impurity anions in the boiler and water-gas system, and help chemists analyze and grasp the current situation of system corrosion, and take corresponding measures in time. Ensure the safe and economical operation of the system. [0003] At present, a set of cation exchange resin exchange column is installed in front of the conductivity meter to measure the conductivity of water vapor and hydrogen in the power plant, and the technicians of the power plant regularly observe whether the resin is invalid. When the resin fails, the technicians of the power plant need ...
