Immersion electrolytic decontamination device

Abstract

The invention relates to an immersion electrolytic decontamination device. The device comprises a decontamination tank, an anode supporting plate and a direct-current stabilized voltage supply, wherein the decontamination tank can contain an electrolytic solution, a cathode supporting plate and cathode plates are arranged in the decontamination tank, the first end of each cathode plate is detachably mounted on the cathode supporting plate through a fastener, and the cathode plates are arranged to extend downwards in the height direction of the decontamination tank; the anode supporting plate is used for mounting a to-be-decontaminated workpiece, the cathode supporting plate is arranged to extend in the direction parallel to the bottom wall of the decontamination tank, and the anode supporting plate is arranged parallel to the cathode supporting plate; and the negative pole of the direct-current stabilized voltage supply is connected with the cathode plates, the positive pole of the direct-current stabilized voltage supply is connected with the to-be-decontaminated workpiece, and the direct-current stabilized voltage supply is used for performing decontamination treatment on the to-be-decontaminated workpiece after being powered on. The device is easy to operate and high in decontamination efficiency; after decontamination, a metal component has the advantages of being reusableand the like, so that operation cost is lowered; and meanwhile, it is guaranteed that generated radioactive pollution is controlled below a safety standard during nuclear energy utilization, and the safety of personnel, the environment and the public is guaranteed.

Description

technical field [0001] The invention relates to the field of nuclear environmental protection equipment, in particular to an immersion-type electrolytic decontamination device. Background technique [0002] Structural decontamination is an indispensable link in the operation of nuclear power plant equipment, especially the decontamination of radioactive contamination of metal materials is particularly important. At present, the traditional methods for decontamination of equipment and workpiece surfaces of metal materials at home and abroad include physical methods and chemical methods. Although physical methods and chemical methods are mature and widely used, there are many problems. For example, the physical method produces radioactive dust, which seriously endangers the health of operators and the environment, and may even produce explosive mixtures; the chemical method has a large amount of secondary waste and is easy to cause corrosion to equipment. The electrochemical ...
