Technical Field
The invention relates to a reflux device for recovering condensed heavy water in deuterium gas by a deuterium gas generator system, in particular to a heavy water recovery device for a deuterium gas generator.
Background
The existing heavy water electrolysis deuterium production equipment adopts a filter-pressing type structure, then a circulating pump is used for forcibly circulating electrolyte on an anode side and a cathode side to take away heat and bubbles generated by electrolysis, and the electrolytic cell structure is called as a double-circulation structure. In order to increase the purity of deuterium gas and reduce the influence of impurities in the electrolyte, an electrolytic cell structure has been developed in which the electrolyte is circulated only on the anode side by increasing the gas pressure on the cathode side, and this electrolytic cell structure is called a single-cycle structure. No matter single-cycle or double-cycle structure electrolytic cells, the gas electrolyzed from the electrolytic cells carries a large amount of heavy water vapor, and the heavy water vapor is condensed into heavy water after passing through a condenser. For the double-circulation structure, in order to avoid wasting expensive heavy water, only the heavy water condensed by the deuterium gas and oxygen condenser is required to flow back to respective phase separators; for the single-cycle structure, the deuterium pipeline cannot be connected to the oxygen-side phase separator in single-side cycle, so that the heavy water condensed from the deuterium is prevented from being wasted due to mixed explosion of the deuterium and the oxygen.

The diaphragm assembly comprises an upper diaphragm clamping plate, a lower diaphragm clamping plate and a water-permeable and gas-barrier diaphragm clamped between the upper diaphragm clamping plate and the lower diaphragm clamping plate.
The further technical scheme is that the upper diaphragm clamping plate and the lower diaphragm clamping plate are both alkali-resistant metal powder sintered plates.
The further technical scheme is that the porosity of the alkali-resistant metal powder sintered plate is 30-40%.
