Radioactive waste liquor entrainment purification equipment

The invention discloses radioactive waste liquor entrainment purification equipment and solves the problems that a traditional entrainment separating technology is not high in separation accuracy and separation efficiency. The equipment comprises a housing assembly (1), a radioactive entrainment inlet (2), a liquor drainage assembly (3), a tray assembly (4), a composite membrane assembly (5) and an air outlet (6), wherein the radioactive entrainment inlet (2) is arranged at the top end of the housing assembly (1), the liquor drainage assembly (3) is arranged at the bottom end of the housing assembly (1), the tray assembly (4) is arranged in the housing assembly (1) and divides the housing assembly (1) into an upper cavity body and a lower cavity body, the composite membrane assembly (5) with the top end arranged on the tray assembly (4) is arranged in the lower cavity body, and the air outlet (6) is formed in the side wall of the upper portion of the lower cavity body. The composite membrane assembly (5) comprises a filter element and an installation assembly, wherein the filter element is composed of a dense fiber bed and the installation assembly is arranged on the filter element and used for fixing the filter element on the tray assembly (4). The entrainment has the advantages of being high in separation accuracy and separation efficiency, good in irradiation-resistant effect and pollution resistance and high in safety performance.
