Abstract

The present invention discloses a gas-liquid exchange type liquid lithium lead alloy bubbler, and belongs to the technical field of a fusion reactor liquid cladding. The gas-liquid exchange type liquid lithium-lead alloy bubbler comprises two parts of a main circuit system and an assistant system. The main circuit system comprises a lithium lead saturator, a filler tower, a lithium lead collector, a gas circuit and a liquid flowing path. The assistant system comprises a measurement-control system and a vacuum system. According to the gas-liquid exchange type liquid lithium lead alloy bubbler of the present invention, the filler tower is arranged; after passing through a porous diffuser, the hydrogen isotope-saturated lithium lead alloy melt flows through a stainless steel filler from top to bottom, and exchanges with belt-carried gas, wherein the belt-carried gas flows through the stainless steel filler from bottom to top; the extraction effect of the hydrogen isotope is significant; the solubility measurement of the hydrogen isotope in the liquid lithium lead is accurate; the high temperature sealing performance is good; the case of plugging due to impurities is not easily generated.

Description

technical field [0001] The invention belongs to the technical field of fusion reactor liquid cladding, and in particular relates to a gas-liquid exchange type liquid lithium-lead alloy bubbler. Background technique [0002] Nuclear fusion reactors are one of the most promising energy systems. Today, the International Thermonuclear Experimental Reactor (ITER), which is co-operated by the European Union, the United States, Japan, Russia, India, South Korea, and China, is a representative sign of progress. The dual-function liquid lithium-lead test cladding (DFLL-TBM) participated by China is one of the cladding schemes that are currently being enthusiastically considered. One of the characteristics of DFLL-TBM is the high tritium breeding ratio (TBR), which can extract tritium from liquid lithium lead by using a helium-hydrogen bubbler. As one of the important components of DFLL-TBM, the tritium processing unit is located on a branch road in the cladding main circuit. The bra...
