Abstract

The invention discloses a tritiated water recycling device which comprises a tritiated water supply device, a second gas recycling pump, a condenser, a tritiated water storage tank, a first adsorption bed and a third adsorption bed. The first adsorption bed and the third adsorption bed are each filled with a 5A molecular sieve. The tritiated water supply device and the first adsorption bed are connected to form a tritiated water removal circuit. The second gas circulating pump, the first adsorption bed, the condenser and the third adsorption bed are connected in sequence. The third adsorption bed is connected to the input end of the condenser in a return mode, so that the second gas circulating pump, the first adsorption bed, the condenser and the third adsorption bed form a tritiated water recycling circuit. The tritiated water storage tank is connected with the output end of the condenser. According to the tritiated water recycling device, recycling of tritiated water in gas can be achieved with no extra carrier gas, only liquid tritiated water is output, no other waste tritium-contained water is generated in the running process, and safety and reliability are achieved; meanwhile, the tritiated water recycling device is connected to technological equipment of a tritium technology laboratory, so that continuous recycling of tritiated water in gas of different types is achieved.

Description

technical field

[0001] The invention relates to a recovery device, in particular to a tritiated water recovery device and its realization method. Background technique

[0002] As we all know, tritium is an isotope of hydrogen, an expensive strategic substance, and also a nuclide with β radioactivity. Tritiated water is the oxidized form of tritium. Tritium can easily generate tritiated water through oxidation reaction or exchange reaction in the atmosphere of water or oxygen. For example, in the tritium removal system of the tritium process laboratory, in order to reduce the content of tritium, catalytic The oxidation method produces tritiated water. In addition, when a tritium leakage accident occurs, tritium will react with water vapor in the gas to form tritiated water.

[0003] The tritiated water produced under the above working conditions is usually removed by molecular sieve adsorption. For example, the Chinese patent number is ZL201420315799.9, the patented technol...
