Abstract

A moving granular bed filter (100) for removing contaminants from a gas or vapor stream (112) employs a quantity of granular media (108) that is passed through a vessel (104) while the contaminant-laden gas stream is passed through the granular media to remove at least a portion of the contaminants from the gas stream and into the granular media. The vessel includes a media inlet (184) that extends between a pair of opposite regions of the vessel and delivers the granular media into the interior (128) of the vessel such that the granular media forms a freely-formed filtration pile (188) within the interior of the vessel to define first and second chambers (200, 204) above the upper surface (192) of the pile and on opposite sides of the media inlet. In one embodiment, the media inlet is disposed at the lower end of a media delivery channel (148) that extends downwardly into the interior of the vessel and which supplies the granular media to the media inlet.
