SYSTEM AND METHOD FOR MEASURING CONDUCTIVITY OF DEGASSED HYDROGEN

摘要

A system and method for measuring the conductivity of degassed hydrogen. A water outlet of a sampling bottle (1) is divided into two paths. One path is connected to an outlet of an acid adding device (3) by means of a pipeline, and the two communicate with an inlet of a first channel in a degassing membrane (4). An outlet of the first channel in the degassing membrane (4) communicates with a water drainage pipeline (9). The other path communicates with a water inlet of an electro-regenerated cation exchanger (5). A water outlet of the electro-regenerated cation exchanger (5) communicates with a water inlet of an electro-regenerated anion exchanger (7) by means of a first conductivity measurement device (6). A water outlet of the electro-regenerated anion exchanger (7) communicates with an inlet of a second channel in the degassing membrane (4). An outlet of the second channel in the degassing membrane (4) communicates with an inlet of a second conductivity measurement device (8). An outlet of the second conductivity measurer (8) communicates with an electrolyzed water channel of the electro-regenerated cation exchanger (5) and an electrolyzed water channel of the electro-regenerated anion exchanger (7). An outlet of the electrolyzed water channel of the electro-regenerated anion exchanger (7) communicates with the water drainage pipeline (9). The invention accurately measures the conductivity of degassed hydrogen in water vapors of a power plant online or offline.
