APPARATUS AND METHOD FOR FLUID PURIFICATION

摘要

An apparatus and method are disclosed for purifying a contaminated fluid stream, for example an air stream contaminated with volatile organic compounds. A sorption media (12c) is directed between narrowly spaced plates which control the depth of sorbant flow. In an adsorber the plates are porou s to allow the contaminated air to pass into an adsorption chamber where the media removes the contaminates from the fluid stream. In a desorber the plat es (28c, 29c) may be transmissive or reflective of microwave energy (30c) and porous to a purging gas (40c) in a desorption chamber where the media (12c) releases the contaminates to refresh the media (12c). An inclined plane or conical surface is contemplated for a desorber which can be coupled to an adsorber in a closed loop system.
