Abstract

The invention discloses an SPE (Solid Polymer Electrolyte) electrolysis system used for tritium concentration. The electrolysis system comprises an electrolytic tank system, a tritiated water supply system, a gas-liquid separator, a tritiated water collection system, a hydrogen drying system, an oxygen drying system, a hydrogen collection system, a product oxygen collection and storage tank, a condensation system and a detection and control system. The invention further provides a realization method for the SPE electrolysis system used for tritium concentration. The electrolysis system can meet all process demands of aqueous phase tritium concentration, wherein the processes include a tritiated water circulating concentration process, a hydrogen leakage emergency power-off process, a molecular sieve drying bed continuous treatment process and the like. Meanwhile, due to the tritiated water circulating concentration, the tritiated water concentration can be quantitatively controlled, so that the tritium concentration efficiency is greatly improved and a large amount of tritium-poor hydrogen is obtained.

Description

technical field [0001] The invention relates to the fields of chemical industry and nuclear technology and equipment, in particular to a SPE electrolysis system for tritium concentration and its realization method. Background technique [0002] Tritium-containing wastewater will be generated during the operation of nuclear power plants. If the radioactive tritium-containing wastewater cannot be properly disposed of, it will cause serious environmental pollution. Moreover, the abundance of tritium in nature is extremely low, and the recovery of tritium in tritium-containing water has high economic value. Therefore, the development of high-efficiency, energy-saving, environmentally friendly, and low-cost water detritization technology and equipment is of great significance for recovering tritium elements and making wastewater meet environmental discharge indicators. [0003] Solid polymer electrolyte (Solid Polymer Electrolyte, SPE) electrolysis, that is, SPE electrolysis, ha...
