This invention relates to the field of regenerative thermal ignition (RTO) control technology, and discloses a method and device for zone switching control of a multi-tower modular RTO system. By deploying a temperature acquisition array on each RTO tower, a two-dimensional temperature matrix is ​​acquired in real time. A comprehensive early warning signal is generated by combining the judgment of temperature field distortion precursors and the judgment of flow deviation risk. The inlet VOC concentration and outlet temperature are monitored in real time. When an early warning is triggered, the switching timing is dynamically adjusted according to the temperature rise state type. Furthermore, an energy imbalance state is determined by constructing an inter-tower energy difference matrix, and a collaborative adjustment mode is triggered synchronously during the switching operation. This invention significantly improves the accuracy of temperature field prediction, reduces the risk of local overheating of the RTO body, optimizes the accuracy of switching decisions, and effectively avoids thermal runaway reactions caused by nonlinear temperature gradient distribution and VOC concentration fluctuations through multi-dimensional data fusion and dynamic adjustment mechanisms, thereby achieving a substantial improvement in the overall thermal efficiency of the system.

This invention relates to the field of waste gas treatment equipment technology, and discloses a regenerative thermal incineration waste gas treatment device, including a support frame. Three regenerative chambers are fixedly connected to the top of the support frame, and a common combustion chamber is fixedly connected to the top of the three regenerative chambers. This invention addresses the problem of local overheating and thermal shock cracking of ceramic honeycomb. An auxiliary mechanism and a pressure mechanism are set inside the device. After the waste gas is purified, a hydraulic press pushes a hydraulic push rod upward, which in turn moves the highest fixed frame two upward. As the hydraulic push rod continues to move upward, the six fixed frames two will separate, and the air inlet pipe will generate a negative pressure suction force, forcing the purified high-temperature gas in the common combustion chamber to flow downward and heat the honeycomb ceramic two and honeycomb ceramic one. This causes multiple sets to separate, allowing the oxygen remaining inside the honeycomb ceramic one and honeycomb ceramic two to diffuse outward at once, while reducing the length of the "combustion channel" and effectively reducing the probability of combustion and explosion.
