ABSTRACT:
A regenerative thermal oxidizer (RTO) is constructed to receive polluted waste gases from an industrial process, cleanse the gas and permit cleansed gas to exit the RTO to the environment. The RTO includes a lower section having an inlet to receive polluted or incoming gas, and a centrally positioned rotary distributor in the lower section for cooperation in controlling gas flow via a segmented center section. The rotary distributor is substantially smaller than the lower section and is of a substantially smaller cross section. Incoming gas is directed to a middle section segment(s), fills the segment(s) and then flows through a peripheral opening to a segmented upper section where it passes through a heat exchanger to a combustion chamber where it is oxidized or cleansed. From there cleansed gas passes through another upper section segment through a heat exchanger and back to center section segment(s). In the center section the cleansed gas flows to the rotary distributor where it is divided into outgoing and purge gases. The outgoing gas flows through the rotor to a manifold and then to an outlet. The purge gas flows through a purge segment in the rotor to a center discharge pipe. From the pipe the purge gas is directed to a conduit for exiting the RTO and the purge gas is then recycled to the incoming gas to the RTO.
