Recycling aparratus and method of waste oil and waste device having carrot for including polychlorinated biphenyl}

According to the present invention, polychlorinated biphenyl (PCBs) used in insulating oils or lubricating oils of electronic devices are included to improve electrical insulation performance and are harmful to the human body. The present invention relates to waste oil containing PCBs for recycling oil and equipment of waste oil, and a waste recycling apparatus and method containing the same.

In general, polychlorinated biphenyls (PCBs) are compounds in which 2 to 10 of the 10 hydrogen atoms of biphenyl are linked to two benzene rings by chlorine atoms. Insoluble in water, good in solubility in organic solvents and stable in acids and alkalis, but long-lasting in soil and seawater.

 The polychlorinated biphenyl may theoretically have 242 isomers, and about 100 species are actually used. It is obtained by reacting biphenyl (C6H5-C6H5) with chlorine under a catalyst such as iron chloride, and various kinds of isomers are formed including monochlorobiphenyl substituted with only one atom of chlorine. Industrially, these are not separated but used in the form of mixtures. Depending on the degree of chlorination, various kinds of products with specific gravity of 1.18 to 1.74 and boiling point of 275 to 360 ° C are produced. Colorless oil, yellow viscous oil, and brown resinous are all insoluble in water and good in solubility in organic solvents. It is a nonflammable compound that is stable to acids and alkalis and heat-resistant, and does not invade ordinary metals other than copper.

Conventionally, it was used as industrial heat medium, the coloring solvent of carbonless copy paper, the insulating oil of a capacitor, the plasticizer of the rubber | gum for a power cable covering, etc. However, it has been banned for use and manufacture at present, as it has been proved that if it remains for a long time in soil and seawater and enters the human body, it causes severe injury to liver and skin.

These polychlorinated biphenyls have been used in insulating oils and lubricating oils in electrical equipment, but they are currently used in transformers and rectifiers in railway vehicles. When they enter the human body, they accumulate in fat or brain, and the poisoning symptoms are pigmentation of nails and oral mucosa and acne. It has been reported to the World Health Organization (WHO), which causes sunspots, follicles, systemic malaise, hand and hand paralysis, destruction of sex hormones, liver failure, and cancer.

As described above, polychlorinated biphenyls have been used in insulating oils to reinforce excellent electrical insulation performance. However, polychlorinated biphenyls are hazardous organic compounds that are toxic and have high toxicity. have.

After using the oil containing polychlorinated biphenyl, it is incinerated at high temperature at the time of disposal, or it is chemically treated to remove the toxicity, and the base oil, rubber compounding oil, and cleaning oil of refined fuel oil, cutting oil and renewable lubricant oil are used.

Condensation in the condenser 164 and the high concentration waste disposal treatment step (S23) to supply to the waste oil storage tank 159 through the high concentration evaporation waste oil supply pipe (166), In the waste pretreatment step (S21), the low concentration waste with a polychlorinated biphenyl concentration of 2 ppm or less is transferred to the low concentration conveyor 167 and supplied to the low concentration dryer 168 to dry the high temperature, and the evaporated waste oil exchanges heat. The low concentration heat exchanger (168a) having a cooler (168b) is supplied to the waste oil supply unit (110) to the low concentration evaporation waste oil supply pipe (169), and the residual gas of the low concentration heat exchanger (168a) is adsorbed through the low concentration adsorber (168c). Low concentration waste treatment step (S24) to remove and discharge; The high-density waste disposal step (S23) and the low-density waste disposal step (S24) transport the discarded waste (1) to the disposal platform 171 to the dismantling work table 172 to classify each part by type and dismantle it. And, containing the polychlorinated biphenyl, characterized in that comprises a waste recycling step (S25) for loading and dismantling the dismantled parts in the recycling bin 174 in a reduced state through the reduction press 173 How to recycle waste with built-in waste oil.
