Abstract
The electrolytic decontaminator for eliminating pollutant from metal surface includes one outer cavity with vacuumizing port for being vacuumized, and one inner cavity with water inlet and water outlet extending beyond the outer cavity and cathode inside the inner cavity and possessing end extending beyond the inner cavity for connection to the negative pole of the power source. The part to be decontaminated serves as the anode connected to the positive pole of the power source, and there are sealing pads set between the electrolytic decontaminator and the decontaminated part. The present invention can decontaminate large metal equipment partially in high efficiency, low cost and less waste producing amount, and the produced waste may be degraded for minimizing.
Description
Technical field
The present invention relates to remove the device of surface contamination, relate in particular to a kind of electrolytic decontaminating device that pollute the metallic surface of removing.
Background technology
Once the electrolytic decontaminating technology is used for radioactive decontamination abroad, and developed a lot of electrolytic decontaminating devices, but mostly be slot type, only be suitable for the electrolytic decontaminating of micro metal parts, then inapplicable for large-scale hardware, pipeline.There are many large-scale hardwares, pipeline after common decontamination, to leave over down during elimination of nuclear facilities decontamination and pollute focus, this pollution focus uses common decontamination method to remove, also can not realize whole hardware, pipeline electrolytic decontaminating, and secondary refuse generation is excessive, the decontamination expense is too high, and is very uneconomical; If not to polluting the focus decontamination, metal waste can't degradation, recirculation, utilize again, and the metal waste generation is big, and disposal costs is too high, and is also very uneconomical, and therefore the pollution focus of large-scale hardware, pipeline is the difficult point of retired decontamination.Develop and a kind ofly be used for the large-scale hardware of nuclear installation, pipe surface to pollute the electrolytic decontaminating device of focus decontamination significant.
Summary of the invention
The present invention is directed to insurmountable large-scale hardware in the prior art, pipeline focus decontamination problem, provide a kind of large-scale hardware, pipe surface of being applicable to pollute the electrolytic decontaminating device of removing.
The present invention removes the electrolytic decontaminating device that pollutes the metallic surface and comprises exocoel that can vacuumize and the inner chamber of placing electrolytic solution, exocoel is provided with vacuum orifice, inner chamber is provided with fluid inlet and liquid outlet, fluid inlet and liquid outlet all stretch out exocoel, negative electrode places inner chamber, the end of negative electrode is stretched out inner chamber and is linked to each other with the negative pole of power supply, treats that the decontamination parts link to each other with the positive pole of power supply as anode, is equipped with gasket on electrolytic decontaminating device and the surface for the treatment of the side that the decontamination parts contact.
Aforesaid electrolytic decontaminating device protrudes in exocoel with the inner chamber for the treatment of electrolytic decontaminating device one side that the decontamination parts contact, and to be applicable to that removing the metallic conduit internal surface pollutes, simultaneously, the negative electrode that places inner chamber is a circular arc type.
Aforesaid electrolytic decontaminating device, concordant with the inner chamber for the treatment of electrolytic decontaminating device one side that the decontamination parts contact with exocoel, remove the hardware surface contamination to be applicable to, simultaneously, the negative electrode that places inner chamber is plate.
Electrolytic decontaminating device of the present invention, adopt the mode of vacuum suck eradicator to be adsorbed on the surface of hardware, pipeline, eradicator is a double cavity structure, electrolytic solution can carry out electrolytic decontaminating in the inner chamber circulation, and exocoel is then kept the certain vacuum degree eradicator is fixed on the decontamination working face.Whole device volume is little, in light weight, and device is installed fast, easy during decontamination, can reduce a staff and be shone.This device is at large-scale hardware, the decontamination of pipeline focus, and do not need whole pipe equipment is carried out decontamination, thereby significantly reduced secondary refuse generation, improved working efficiency, reduced the decontamination expense, metal waste after the decontamination can pass through degradation, recirculation, utilize, reduces disposal costs, realizes waste minimization.
