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.
