APPARATUS AND METHOD AND FOR TREATMENT OF WASTE INSULATING OIL

摘要

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.
