Liquid lead bismuth alloy oxygen reduction filter

The invention discloses a liquid lead bismuth alloy oxygen reduction filter which mainly comprises a main pipeline, a bypass pipeline, a reaction cavity, an inner sleeve, a charging container, a coarse-mesh filter screen, a fine-mesh filter screen, a high-purity aluminum ball, a long sliding rod, a fixed flange, a sealing flange and the like. Liquid lead-bismuth alloy with the dissolved oxygen concentration of C [O] 0 simultaneously enters the main pipeline and the bypass pipeline from the reaction cavity when flowing into the oxygen reduction filter. The liquid lead-bismuth alloy entering the bypass pipeline firstly passes through a second coarse-mesh filter screen and a second fine-mesh filter screen and then flows through a high-purity aluminum ball bed to chemically react with the surfaces of high-purity aluminum balls, particles PbO in the liquid lead-bismuth alloy are reduced by high-purity aluminum, and the concentration of dissolved oxygen is reduced to C [O] 1. The liquid lead-bismuth alloy entering
