ABSTRACT:
A method and apparatus for stripping entrained organic vapor and solid particulate matter from a pyrolytic off-gas stream is disclosed. The off-gas is introduced at the top of a conical chamber having a variable speed "squirrel cage" rotor at its top. The wet, dirty, off-gas is drawn into the rotor from below and impinged upon the chamber walls which causes part of the organic vapor to condense and flow to the chamber bottom, thereby cleaning the chamber walls. A portion of the impinged gas is recirculated through the rotor while the remainder exits at the chamber bottom. The ratio of recycled gas to through gas is controlled by the speed of the rotor. Heating and cooling coils on the chamber walls are operable to control the rate of condensation.
