MODULAR VOC ENTRAPMENT CHAMBER FOR A TWO-CHAMBER REGENERATIVE OXIDIZER

摘要

Regenerative oxidizer including an entrapment chamber and damper assembly, aswell as a method of oxidizing volatile organic compounds in a gas using suchapparatus. To improve the VOC destruction efficiency and eliminate opacityissues resulting from heat exchange matrix regeneration, untreated fluid canbe diverted away from the oxidizer exhaust stack and directed into a "holdingvessel" or VOC entrapment chamber. The assembly utilizes a single damper inorder to divert the exhaust flow from the oxidizer either to exhaust or to theentrapment chamber. The entrapment chamber preferably has a modularconstruction, which facilitates expanding or decreasing the volume of thechamber. The design facilitates installation and can be retrofitted onexisting equipment. The damper diverts the flow of gas with minimal or nonegative impact on the process flow.
