Device of recycling tritium from tritiated water and implementation method of same

The invention discloses a device of recycling tritium from tritiated water, which includes, in a successively connected manner through pipelines, a gas circulating pump, a buffer tank filled with an inert carrier gas, a tritiated water storage tank filled with the tritiated water, a first water decomposing bed filled with iron powder, a first adsorption bed filled with a 5A molecular sieve, and a first hydrogen storage bed filled with a zirconium-series hydrogen-storing alloy. The first hydrogen storage bed is also back-connected to the gas circulating pump. The device is compact in structure, is low in cost, is convenient to use, can be used for recycling the tritium from tritiated water continuously without generation of solid waste, and has excellent practical and popularizing values.
