    摘要： The present invention provides a PCB decomposing apparatus capable of decomposing PCB efficiently. The PCB decomposing apparatus comprises a PCB extracting container for extracting PCB from a PCB-containing material with an organic solvent. A distilling tower provided on the downstream side of the PCB extracting container distills the organic solvent to separate the PCB. A primary reactor provided on the downstream side of the distilling tower includes a nozzle for supplying aqueous Na2CO3 solution and a nozzle for supplying an oxidizing agent into the container. A liquid cyclone provided on the downstream side of the primary reactor can remove Na2CO3 having a large particle size. A secondary reactor formed by a long pipe is connected to the liquid cyclone. A gas-liquid separator provided on the further downstream side of the secondary reactor can separate a gas from a solution. A film separator separates treated water into purified water and a concentrated solution, and the purified water is supplied as circulating water to the upstream side of a pressure pump.

    摘要： This invention provides a PCB decomposition reactor which can decompose PCB efficiently. In this PCB decomposition reactor, an injector for injecting a mixture of water and sodium hydroxide into a reaction vessel is connected to the lower part of the reaction vessel. An outlet pipe for withdrawing the fluid treated within the reaction vessel is connected to the sidewall of the reaction vessel. The other end of the outlet pipe is connected to a cyclone for separating sodium carbonate from the treated fluid. A discharge pipe is connected to the top of the cyclone, so that the treated fluid from which the precipitated sodium carbonate has been removed is discharged therethrough. A downcomer for the separated fluid is connected to the bottom of the cyclone, so that the precipitated sodium carbonate and some fluid containing it are discharged therethrough. The lower end of the downcomer is connected to an injector, which has connected thereto a feed pipe for feeding a mixture of PCB and mineral oil. A gas supply nozzle for injecting a gas into the reaction vessel is installed at the bottom of the reaction vessel.
