MICROWAVE DESORBER FOR REMOVING CONTAMINANTS FROM RESIN

摘要

A microwave desorber (10)removes volatile organic compounds from resins in order to recycle the resins. The desorber (10) includes a container (12) adapted to receive the contaminated resin, and at least one waveguide (16) adapted to introduce microwave energy into the contaminates in the container (12). At least one of the container (12) and the waveguide (16) can be moved, relative to the other, such as oscillated, radially or axially, with a mechanism (44, 46, 48) to facilitate uniform heating of the contaminates. The contaminated resins can be moved through a preferred radial zone (32) of the container (12) in order to optimize the microwave heating in accordance with the particular contaminates or resins.
