In the conventional sodium metal dispersing method using a chemical dechlorination reaction, a solvent cleaning apparatus and a vacuum heating segregation equipment treatment process are required in order to remove polychlorinated biphenyl remaining in the transformer, etc. However, an object of the present invention is to provide a treatment method and apparatus for rapidly disposing polychlorinated biphenyl within waste insulating oil containing polychlorinated biphenyl without the above treatment processes and decomposing polychlorinated biphenyl remaining in members (a container, iron core kinds, paper or wood kinds, etc.) within a transformer. Further, the present invention provides a movable type treatment apparatus that can be used in an area of a degree that it can be installed on even a vehicle by using a simplified treatment process without a large treatment factory plottage. In the conventional sodium dispersing method, a contact probability between a dechlorination reagent and molecules of polychlorinated biphenyl is enhanced through thermal dispersion in order to improve a reaction probability between the dechlorination reagent and the polychlorinated biphenyl molecules by raising temperature. Accordingly, a high reaction temperature (160 to 170 degrees Celsius) has to be maintained as possible and therefore there are problems in that lots of energy is consumed in the reaction furnace and the expenses at the time of treatment are increased. The present invention has improved the above problems and provides a method of sufficiently generating a desired reaction even at a low temperature of about 130 degrees Celsius by increasing the contact probability between the dechlorination reagent components and the polychlorinated biphenyl molecules within waste insulating oil through not only thermal dispersion, but also physical dispersion. Accordingly, the present invention is economic when compared with other treatment methods.
Description
technical field [0001] The present invention relates to a method for decomposing and treating waste insulating oil containing polychlorinated biphenyls (PCB) which is harmless from an environmental point of view, and for purifying waste insulating oil containing PCB (i.e. persistent organic pollutants) treatment device. Background technique [0002] PCBs have been used in various applications such as insulating oil, heating medium, lubricating oil and plastics, and thus have high practical value. In addition, since PCBs are not flammable, have no fear of thermal denaturation and are very stable chemically, and also have excellent insulating or electrical characteristics, they have been used in various applications. [0003] PCBs are basically compounds in which biphenyl (C 6 h 5 -C 6 h 5 ) is substituted by 1 to 10 chlorine atoms at ten hydrogen atom positions, and can theoretically have 242 isomers, but about 100 of them are actually used. Polychlorinated biphenyls do...
