Description

Technical Field

[0001] The invention relates to the field of waste gas purification, and in particular to a rotary heat storage combustion VOCs organic waste gas purification device. Background Art

[0002] The rotary thermal storage combustion (RTO) VOCs organic waste gas purification device is a common technology for treating industrial waste gas. It uses high temperature to burn volatile organic compounds (VOCs) in organic waste gas and recovers heat energy through a thermal storage system.

[0003] For example, the authorization announcement number is: CN114623456B discloses a single-valve rotary heat storage combustion VOCs gas treatment equipment, including, a gas distribution chamber, a plurality of gas distribution chambers are arranged in sequence along the circumferential direction and fixedly connected, each gas distribution chamber is connected to a ventilation pipe group, and a cavity is left between the plurality of gas distribution chambers; a heat storage chamber, each heat storage chamber corresponds to a gas distribution chamber one by one and is installed on the top of the gas distribution chamber, adjacent heat storage chambers and gas distribution chambers are separated by a first filter plate, and heat storage bricks are arranged in the heat storage chamber; a combustion chamber, the combustion chamber is installed on the top of the heat storage chamber, and the combustion chamber is connected to each heat storage chamber, and the combustion chamber and the heat storage chamber are separated by a second filter plate;

[0004] This patent stores heat in a heat storage chamber. The current rotary heat storage combustion structure uses a rotary valve to switch the exhaust gas to connect with the heat storage chambers at different positions, but the current rotary valve cannot control the ventilation volume, which will bring a problem, that is, it is impossible to control the heat exchange time of the exhaust gas after combustion in the heat storage chamber. Since the amount of exhaust gas generated and the temperature of the exhaust gas itself are changing, for example, if the amount of exhaust gas is small, the heat after combustion will also become less. At this time, if the heat exchange time of the exhaust gas after combustion in the heat storage chamber cannot be controlled, it will cause insufficient heat storage temperature in the heat storage chamber. After switching the intake direction, the preheating temperature of the exhaust gas after passing through the heat storage chamber will also be affected, thereby affecting the combustion effect entering the combustion chamber.
