Abstract
A method of and device for cleaning hot gases, especially industrial waste ases, according to which the gases to be cleaned are passed between plates or discs rotatable about an axis and arranged in spaced relationship to each other, e.g. spaced from each other by a few millimeters. At least one component to be separated from the gases to be cleaned is adapted to form a compound with a layer of a solid substance which has been deposited upon the surface of the plates as a liquid, especially as an aqueous solution, and has been dried. The solution forming the layer of solid substance is sprayed upon the plate surface or at least portions thereof. After reaction of the layer of solid substance with the gases, the layer of solid substance is at least partially withdrawn from the gas space between the respective adjacent plates.
