[0002] Thermal storage combustion equipment (RTO) is a technology that heats up and burns waste gases such as VOCs at high temperatures. Gases containing VOCs are burned at a high temperature of 830°C, and the heat generated is used for heat exchange. At the same time, the heat energy is stored through thermal storage ceramics. This technology can effectively treat organic solvents or organic odors. At the same time, the combustion heat generated is not directly discharged into the atmosphere, but is recovered and stored or recycled through heat storage bodies (thermal storage ceramics) for heat exchange, thereby achieving the purpose of air pollution prevention and control. According to different projects and industries, part of the waste heat that should be discharged can be recovered and sent to the factory (project) for use;

[0003] Existing heat storage combustion equipment generally has a built-in filtering device at the bottom, which distributes the exhaust gas while filtering, and introduces the exhaust gas into the equipment. After treatment, the clean gas is filtered again by the filtering device and directed to be discharged. In the whole process, the filtering equipment is very important. Once a problem occurs or maintenance is required, the operation of the entire equipment needs to be stopped, which affects the processing efficiency. Therefore, the utility model proposes a special RTO exhaust gas treatment equipment to solve the problems existing in the prior art. Utility Model Content
