Title:
PCB混入絶縁油の無害化処理設備
Document Type and Number:
Japanese Patent JP5425716
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a de-toxifying equipment for PCB mixed-in insulating oil, pre-treating the PCB mixed-in insulating oil containing impurity without generating waste, waste liquid and drainage to stably de-toxify the PCB mixed-in insulating oil, and also reducing the consumption of metallic sodium.SOLUTION: This de-toxifying equipment for the PCB mixed-in insulating oil includes an oil purifying apparatus 50 for filtering out impurity in the PCB mixed-in insulating oil by filters 52a, 52b, wherein the PCB mixed-in insulating oil, the impurity of which is removed or reduced is caused to react with the metallic sodium to de-toxify the PCB. The oil purifying apparatus 50 is provided with a backwashing device 56 for the filters 52a, 52b including an electrolyzing device 64 for electrolyzing backwashing water which back washes the filters 52a, 52b and a backwashing water tank 66 for storing the electrolyzed water, whereby the filters 52a, 52b can be backwashed without generating waste, waste liquid and drainage.
