The utility model relates to the technical field of caustic soda flake processing, in particular to a dilute alkali liquor circulating system of a caustic soda flake flaker, which comprises a dilute alkali tank and a concentrated alkali tank, a liquor inlet of the dilute alkali tank is communicated with an alkali liquor outlet groove of the caustic soda flake flaker through a pipeline, and a liquor outlet of the dilute alkali tank is connected with a first circulating pump. A liquid outlet of the first circulating pump is communicated with an alkali liquor outlet groove of the caustic soda flaker through a first branch pipeline, a liquid outlet of the first circulating pump is communicated with a liquid inlet of the concentrated alkali tank through a second branch pipeline, and switch valves are arranged on the first branch pipeline and the second branch pipeline. Alkali dust in the alkali liquor outlet groove of the caustic soda flaker is circularly flushed through the dilute alkali liquor, so that the conce
