ROTARY ADSORPTION ASSEMBLY

摘要

An apparatus (10) for adsorptive filtering of contaminants from a gaseous stream is provided. The apparatus (10) includes a frame member (12). The frame (12) includes a base member (16) which is rotatable about an axis (18). A plurality of walls (20) are attached to the base member (16) and extend axially thereform to a top member for providing a plurality of circumferential segments areas (22). The walls (20) include a radially inner side (24) for defining an axially extending inner chamber (26) and a radially outer side for defining an outer periphery (28). A plurality of adsorption elements (14), each having an axial first, side (32) and an axial second side (34), are axially spaced in each of said circumferential segment areas (22). A duct (36) or the like radially directs contaminated air into at least an entire one of the segment areas (22). The apparatus (10) has a duct (36) arrangement for directing a substantially radial flow of air into at least one of said segments (22) from the outer periphery (28) through the axial first side (32) of each of said adsorption elements (14) in generally an axial direction through the adsorption element (14) to exit the axial second side (34) and into said axially extending inner chamber (26) for exhausting decontaminated air out through the axial chamber (26). The present invention may also include a regenerative portion (46) which can regenerate the adsorptive elements (14) during operation of the apparatus (10). The regenerative portion (46) includes ducts (48 and 50) for supplying a heated regenerative air stream and a cooling air stream to strip contaminants from the adsorptive elements (14) and then cool them to a suitable adsorptive temperature.
