ECTW-1 Water Electrolyzer for Tritium Enrichment
Working Principle
Since deuterated water (HTO) is more difficult to electrolyze than water (H2O), the ECTW-1 employs a solid polymer eclectrolyte (SPE) to catalyze electrolysis, thereby concentrating tritium in water.
Software Controls
Product Features
Adopting a unique and innovative design, it has obtained the national invention patent
Adopting SPE membrane method, it does not involve acid-base neutralization reaction, does not need liquid nitrogen, carbon dioxide and other materials, and do completes all operations with one key
It control circuit by liquid level, pressure, temperature and other signals, to realize the automatic control of the entire electrolytic process
The electrolysis temperature is always kept at about 5-10℃, avoiding blockage due to water vapor freezing.
The SPE membrane electrolytic cell was used to electrolyse the concentrated set at constant temperature, so the device showed excellent stability with the deviation of electrolysis time less than 2%.
A unique laser liquid level control sensor is used to accurately control the residual amount of each electrolysis.
The service life of the electrolytic cell is greater than 6,000 hours.
H2 and O2 produced during the electrolysis process are respectively isolated by the semi-permeable membrane, to avoid combustion and explosion caused by mixing of H2 and O2 in the device.
Multiple safety redundancy designs such as air pressure sensor, hydrogen leakage sensor (selected) and outdoor exhaust port ice condensation protector (selected in frozen areas) are adopted to further improve safety.
