Abstract

The invention relates to a continuous permeation extraction device for retention hydrogen isotopes of a liquid metal divertor, and belongs to the technical field of hydrogen isotope extraction.The continuous permeation extraction device comprises a glove box, a linear plasma device, a first lithium tank, a capillary porous target plate and a permeation target. The liquid metal enters the linear plasma device, the fusion reactor divertor hydrogen isotope plasma environment is simulated, the liquid metal interacts with hydrogen plasmas in the linear plasma device, the liquid metal flows into the permeation target, and hydrogen isotopes permeated into the liquid metal are extracted through the mass spectrometer. And finally, flowing into a lithium tank II for storage. Lithium in the second lithium tank is pressed into the first lithium tank through argon, one-time circulation is completed, and continuous operation is formed in cycles. And the method is simple to operate, obvious in effect and short in time, and has important practical significance and progressive significance for reducing the permeation loss of the hydrogen isotope and promoting the development and application of a hydrogen isotope fuel technology in the extraction process of the hydrogen isotope.
