The utility model discloses a high -efficient recovery unit of hydrogen isotope based on catalytic reaction and membrane separation are cascaded, aim at solve current membrane reactor and carry out hydrogen isotope when retrieving, and more foreign gas can lead to the palladium base film to ooze the hydrogen speed reduction in the raw materials, and its best application temperature is difficult to the problem compromise with catalytic reaction speed. The device includes feed gas, fixed bed reactor, palladium membrane hydrogen separator, gas holder, booster pump etc. The utility model discloses a catalytic reaction and the non - normal position integrated mode of membrane separation can effectively improve palladium membrane's utilization ratio, reduce foreign gas to palladium membrane's the effect that poisons, and extension palladium membrane's life can effectively improve hydrogen isotope's the rate of recovery simultaneously. Furthermore, the utility model discloses closed circulation can also be formed, higher hydrogen isotope recovery efficiency can be obtained. The utility model relates to a rationally, strong adaptability can satisfy hydrogen isotope's recovery demand, has the higher rate of recovery, to realizing the fuel recycle of fusion reactor deuterium tritium, the economic nature and the security that improve the reactor, has important meaning.
