Abstract
An effluent gas scrubbing system is disclosed having an improved scrubber inlet system including a transition tube having a fluted lower portion for directing particulate carrying gas into the mist saturated scrubbing chamber of a gas scrubber, a fluid reservoir affixed to the upper portion of the transition tube and having a plurality of fluid supply jets tangentially positioned along internal cavity forming walls of the reservoir so as to cause the fluid within the internal cavity of the reservoir to swirl, and a readily interchangeable gas inlet pipe which is co-axially positioned within the cavity and with respect to the transition tube so as to create a transition gap between the transition tube and the inlet pipe through which a swirling flow of fluid may exit the cavity and enter the upper portion of the transition tube so as to thoroughly coat the entire length of the transition tube with fluid, and so as to provide a smooth and abrupt transition between the dry-walled inlet pipe and the wet-walled transition tube.
