The invention provides a multistage bubbling tower type gas-liquid contactor tritium extraction device and method, which is used for extracting tritium from a helium-cooled lithium-lead proliferation cladding of a superconducting magnetic confinement fusion reactor, and comprises a multistage series mechanism arranged at an outlet of the helium-cooled lithium-lead proliferation cladding and used for extracting tritium dissolved in eutectic lithium-lead alloy through carrier gas, the multi-stage series mechanism is formed by sequentially connecting multiple stages of GLC units in series, the height of each stage of GLC unit is decreased stage by stage, and the stage number of the multi-stage series mechanism is larger than or equal to thirteen. All the stages of GLC units are communicated through connecting pipes arranged at different heights, and all the stages of GLC units are arranged in the direction perpendicular to the horizontal plane, so that the problem that the liquid levels of all the GLC units are not uniform in the operation process is solved, and the overall operation stability and safety of the device are improved. Through verification, the tritium extraction efficiency of the thirteen-stage series connection mechanism can reach 90% or above, and the tritium self-sustaining operation efficiency requirement of the magnetic confinement fusion reactor can be met.

The application discloses an anti-freezing solution for a heat source tower, which is composed of organic salt, acrylic acid polymer, quaternary ammonium salt, benzotriazole, sodium molybdate, alcohol and water. The anti-freezing solution is obtained by mixing organic salt, acrylic acid polymer, quaternary ammonium salt, benzotriazole, sodium molybdate, alcohol and water, and is used in the anti-freezing process of the heat source tower system in the north. The organic salt is used as an anti-low-temperature agent, and the pyridine quaternary ammonium salt, benzotriazole and sodium molybdate mainly play a corrosion protection role. The anti-freezing solution has obvious synergistic effect among the components, and the freezing point of the obtained anti-freezing solution is lower and more stable. The anti-freezing solution has the characteristics of corrosion resistance to carbon steel, stainless steel and copper, so as to meet the technical requirements of the anti-freezing solution used in the heat source tower heat pump in the north. In addition, the obtained anti-freezing solution also has the characteristics of low cost and good environmental protection.
