Abstract:
A PCB decomposition reactor comprising:(a) a reaction vessel for decomposing PCB therein;(b) a cyclone separator disposed in flow communication with an outlet of said reaction vessel for separating sodium carbonate particles from a reaction fluid withdrawn through said outlet, wherein said outlet is formed in a sidewall of said reaction vessel, said reaction vessel being equipped with an injector connected thereto for injecting water and sodium hydroxide from an outside to an inside of said reaction vessel, and a pipe connected to a suction chamber of said injector for introducing the sodium carbonate particles separated by said cyclone separator into said suction chamber, said injector comprising a suction port; and(c) a feed pipe for feeding PCB and a solvent therefor to said reaction vessel, said feed pipe being connected to a flow path between an end of said injector connected to said reaction vessel and the suction port of said injector for supplying water and sodium hydroxide therethrough such that the pH in the reaction vessel is from 7.5 to 13.
