Provided is a regenerative thermal oxidization
system which solves the problem that a regenerative
thermal oxidizer (RTO) is completely connected to production equipment by a duct when a
damper open to the
atmosphere is closed and, accordingly, a static pressure fluctuation generated when an inlet or outlet
damper of the RTO is switched is transmitted to the production equipment via the duct, as well as the problem that there is a possibility that a duct open to the
atmosphere, which is installed instead of the
damper open to the
atmosphere, functions as an atmospheric buffer and, accordingly, the amount of
exhaust gas from the production equipment varies depending on the amount of production, and the leakage of the
exhaust gas from the duct open to the atmosphere and the suction of
atmospheric air occur. The regenerative thermal oxidization
system is provided with a
differential pressure transmitter whereby a duct open to the atmosphere, which is installed in an intake duct that connects the blower of the regenerative
thermal oxidizer (RTO) and the exhaust blower of production equipment that generates
exhaust gas, is connected to the control damper or the
air blower operation
inverter of the RTO, said damper or
inverter being disposed between the
differential pressure transmitter and the blower of the RTO.
