A counter-current solid-gas scrubber for the removal of SO.sub.2 and other undesirable components from stack gas has been invented. The construction of the chamber allows self-leveling of the solids and continuous flow of particulate solids and gases without grates or agitation. The chamber has a plate on the inside which extends downwardly such that a space is formed below the plate. The plate has a gas exit formed by the space below.
