Abstract

The invention discloses a high-efficiency tritium removal purification device and a tritium removal method thereof. The high-efficiency tritium removal purification device comprises a cabinet body, a gas circulating pump, a gas storage tank, a vacuum pump, a flow controller, a catalytic air suction device and an adsorption bed, wherein the vacuum pump, the flow controller, the catalytic air suction device and the adsorption bed are respectively arranged inside the cabinet body; the gas circulating pump, the flow controller, the catalytic air suction device and the adsorption bed are successively connected to form a circulation loop, and the vacuum pump is connected into the circulating loop; the catalytic air suction device comprises a catalytic oxidation device and an alloy adsorption device in parallel, the catalytic oxidation device comprises a first electromagnetic valve, a catalytic bed and a second electromagnetic valve which are connected in sequence, and the alloy adsorption device comprises a third electromagnetic valve, a getter bed and a fourth electromagnetic valve which are connected in sequence; the flow controller is connected with the first electromagnetic valve and the third electromagnetic valve at the same time, and the adsorption bed is connected with the second electromagnetic valve and the fourth electromagnetic valve at the same time; a gasket is further arranged inside the catalytic bed. When the concentration of tritium in a tritium system exceeds the standard or the tritium leakage occurs, tritium-containing gas is quickly transferred and treated, so that the purification of the tritium is effectively realized.

Description

technical field [0001] The invention relates to a recovery and purification device for radioactive waste, which belongs to the field of safety protection in tritium chemistry and tritium technology, and specifically relates to a high-efficiency tritium removal purification device and a method for removing tritium. Background technique [0002] Tritium is a strategic substance, not only expensive, but also not easy to obtain; at the same time, tritium is a highly mobile radionuclide, its leakage will pollute the environment and bring great harm to the human body. Therefore, any operation involving tritium must implement strict radiation protection and environmental discharge requirements. According to the current safety concept, tritium facilities should establish a triple containment system, and at the same time use a combination of physical shielding and detritium purification to solve the problem of the effectiveness of tritium containment. Both the secondary containm...
