Abstract
A regenerative thermal oxidizer (RTO) with three or more chambers. Each chamber would be in a unique mode, (inlet, outlet, purge). Each chamber has its gas flow determined by two poppet valves which define which mode the chamber will be in: inlet mode, output mode, or purge mode.
Claims18
A regenerative thermal oxidizer apparatus, comprising:
- a first chamber opening into an inlet manifold, an outlet manifold, and a purge manifold, a first chamber first valve controlling access from the first chamber to the inlet manifold, a first chamber second valve controlling access from the first chamber to the outlet manifold, and a first chamber purge valve controlling access from the first chamber to the purge manifold;
- a second chamber opening into the inlet manifold, the outlet manifold, and the purge manifold, a second chamber first valve controlling access from the second chamber to the inlet manifold, a second chamber second valve controlling access from the first chamber to the outlet manifold, and a second chamber purge valve controlling access from the second chamber to the purge manifold;
- a third chamber opening into the inlet manifold, the outlet manifold, and the purge manifold, a third chamber first valve controlling access from the third chamber to the inlet manifold, a third chamber second valve controlling access from the third chamber to the outlet manifold, and a third chamber purge valve controlling access from the third chamber to the purge manifold;
- a processing unit configured to selectively control the first chamber first valve, the first chamber second valve, the second chamber first valve, the second chamber second valve, the third chamber first valve, the third chamber second valve, such that the processing unit is configured to put the regenerative thermal oxidizer into a first sequence whereby the processing unit is configured to operate the first chamber first valve to seal the first chamber from the outlet manifold, and to operate the first chamber second valve to expose the first chamber to the inlet manifold, and to operate the second chamber first valve to seal the second chamber from the outlet manifold and to operate the second chamber second valve to seal the second chamber from the inlet manifold, and to operate the third chamber first valve to expose the third chamber to the outlet manifold and to operate the third chamber second valve to seal the third chamber from the inlet manifold,
- wherein the regenerative thermal oxidizer is configured to enable contaminated gas to enter the inlet manifold and to enable processed gas to exit the regenerative thermal oxidizer via the outlet manifold,
- wherein the first chamber first valve, the first chamber second valve, the second chamber first valve, the second chamber second valve, the third chamber first valve, the third chamber second valve are all poppet valves.
