Abstract

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.

Description

technical field

[0001] The present invention relates to a thermal storage combustion exhaust gas purification system and its operating method. The thermal storage combustion exhaust gas purification system includes a regenerative thermal exhaust purification device (Regenerative Thermal Oxidizer) (hereinafter referred to as RTO), Suction duct device for mitigating static pressure fluctuations corresponding to air volume fluctuations during operation of combustion-type exhaust gas purification systems.

[0002] More specifically, it relates to a regenerative combustion type exhaust gas purification system and an operation method thereof provided with a suction duct device, and for the suction duct device, the suction duct at the time of gate switching in order not to apply RTO to the production equipment which is the source of exhaust gas generation Influenced by fluctuations in static pressure, an air-opening duct is installed in the suction duct, and the suction duct connects...
