APPARATUS AND METHOD FOR THE REMOVAL OF GASEOUS POLLUTANTS FROM AN UPWARDLY FLOWING GAS STREAM

摘要

The present invention is a method and apparatus for the removal of gaseous pollutants from a gas stream. The method comprises injecting an adsorbent in a countercurrent direction into a turbulent region of the gas stream. The apparatus comprises a vertical adsorption column having a convergent inlet cone, throat and a divergent outlet cone. A vortex generator is mounted in the throat coaxially with the gas flow. An unobstructed annular area exists around the vortex generator. In this way a region of turbulence of the gas stream is created surrounding the central longitudinal axis of the apparatus and a laminar flow of gas is created along the walls of the apparatus.
