摘要
A fluid flow diverter is provided that includes a diverter body having four ports, a rotating plenum located within the diverter body, and a purge fluid assembly that supplies a purge fluid to the plenum. The plenum has two stop positions that each define a fluid flow path through the diverter. In the first fluid flow path, a first fluid stream goes between the first and second ports, and a second fluid stream goes between the fourth and third ports. In the second flow path, a first fluid stream goes between the first and third ports, and a second fluid stream goes between the fourth and second ports. The purge fluid supplied to the plenum creates a positive pressure fluid barrier that prevents or minimizes cross-contamination of the two fluid streams through the diverter. Also provided is a regenerative thermal oxidizer that includes such a fluid flow diverter.
