摘要： A rotary regenerative catalytic oxidizer is disclosed which is a portable, compact system that catalytically destroys VOC and odorous compounds at elevated temperatures of 400 to 800° F. Equipped with a very high thermally efficient rotor of 90+%, most heat for reaction is retained in the apparatus, and the cleaned air at temperatures of 80 to 120 F. is safely discharged into room without causing discomfort. As a portable unit, it can be conveniently used to treat local areas where odorous and/or hazardous VOC and CO compounds are present and conveniently run off household 120V or 220V systems.

摘要： A system for the abatement of industrial process gases utilizes a rotary regenerative oxidizer comprised of one or more heat exchange beds, each bed comprised of a parallel, axial, and longitudinal array of heat regenerative channels that thermally and/or catalytically oxidize contaminated gases. Utilizing a rotary regenerative oxidizer, and if desired, a plurality of heat regenerative beds incorporated therein, facilitates the use of regenerative technology at lower gas flow rates, increases thermal efficiency, and significantly reduces the floor space normally required when implementing fixed-bed nonrotary regenerative oxidizers. The heat exchange channels may be catalytically treated to enhance oxidation of the pollutants at a lower temperature.
