ことである。The biphenyl compound produced by the dechlorination is dissolved in the refined electric insulating oil 1b, but has a very small amount and does not affect the performance as the electric insulating oil at all. Further, since the biphenyl compound can be easily separated from the electric insulating oil 1b by a separation operation such as distillation, there is no particular problem in reusing. When the purification reaction is completed, the mixture of the electric insulating oil 1b and the saline solution 14 is discharged from the outlet 9 of the purification device main body 5. Electric insulating oil 1 whose purification reaction has just finished 1
Since the mixture of b and saline 14 is high in temperature, it is cooled through a cooler 15 for cooling to a temperature convenient for handling, and then cooled by an oil / water separator 16 into the electrical insulating oil 1b and the saline 1
The electric insulating oil 1b which has been separated into 4 and from which the organochlorine compound has been removed can be reused as electric insulating oil. Here, an important point of the present invention is that the refining treatment of the electric insulating oil 1a can be continuously performed, and the industrial practicality is high.

能である。The present invention relates to a device for removing and purifying an organic chlorine compound contained in the electric insulating oil 1a, and the cooler 15 is not a necessary component of the present invention. Since the refining of the electrical insulating oil 1a requires a considerable amount of time, an industrially important requirement that the electrical insulating oil 1a be continuously purified by the cooling effect of the refining device main body 5 and the pipes is required. If it can be satisfied, cooler 15
Can be omitted. In the example of FIG. 1, the heater 4 and the cooler 15 are provided separately from the refining apparatus main body 5. However, heating may be performed by an appropriate simple method such as an electric heater, and the heating unit 4 and the cooler 15 are integrated with the refining apparatus main body 5. It may be. Whether the heater 4 and the cooler 15 are integrally formed with the purifying apparatus main body 5 or individually as shown in FIG. 1 may be determined depending on the scale of the purifying apparatus main body 5 so as to obtain an optimal configuration. FIG. 2 schematically shows the entire purification process described above. In addition, since the flammable hydrogen gas 11 is used as the nitrogen gas 17 in FIG. 1, it is used for security for inactivating the nitrogen gas 17 by mixing and replacing it in case of emergency. It is not the gist of. Further, the used hydrogen gas is released into the atmosphere via the gas purifier 18, but can be recovered and reused.

危険を回避することが可能である。The refining apparatus of the present invention utilizes a gas-liquid reaction of a catalyst sealed in a closed vessel in a hydrogen gas atmosphere, and is a simple and highly economical apparatus. Moreover, the electrical insulating oil detoxified by removing the organic chlorine-based compound can be reused because the performance is completely restored as the electrical insulating oil, and the by-product is only harmless saline, It is a refining device with extremely low environmental load. In addition, the refining device is configured to be transportable, so that the refining device is transported to the place where the electrical insulating oil to be purified is located, and the refining process is performed. It is possible to avoid such dangers.
