AI Technical Summary
The existing oxygen isotope separation unit has excessive energy consumption, mainly because the steam generated in the downstream column needs to be condensed multiple times and then returned to the upstream column for reboiling, resulting in excessive energy consumption.
By employing a multi-stage distillation column and steam injection assembly, and through the combination of steam ejector and steam generator, high-pressure steam injection and heat transfer are achieved, reducing the condensation process and lowering energy consumption.
By using stepwise separation and heat transfer, the energy consumption of the oxygen isotope separation device was reduced, and the enrichment efficiency of oxygen-18 and the energy efficiency of the device were improved.
