[0032] Working principle:

[0033] During the start-up stage of the device, the waste gas inlet pipe 3 connected to the first heat storage chamber 2, the oxygen inlet pipe 4 connected to the second heat storage chamber 2, and the exhaust pipe 5 connected to the third heat storage chamber 2 are opened, and the igniter in the incineration chamber 1 is started at the same time. At this time, the waste gas and oxygen are fully mixed in the incineration chamber 1 and undergo incineration reaction, and the high-temperature combustion gas generated enters the third heat storage chamber 2, where it exchanges heat with the heat storage bodies in the heat storage body carrier 7. The gas temperature decreases and is then discharged through the exhaust pipe 5. Next, the system switches the valves, opening the waste gas inlet pipe 3 connected to the second heat storage chamber 2, the oxygen inlet pipe 4 connected to the first heat storage chamber 2, and the exhaust pipe 5 connected to the second heat storage chamber 2 (at this time, the first heat storage chamber 2 has completed heat exchange and is preparing for the next round of incineration by admitting gas and oxygen). The waste gas and oxygen are incinerated again in the incineration chamber 1, and the generated gas enters the second heat storage chamber 2 for heat exchange and is then discharged through the exhaust pipe 5. Then, the above switching steps are repeated, opening the waste gas inlet pipe 3 connected to the third heat storage chamber 2, the oxygen inlet pipe 4 connected to the second heat storage chamber 2, and the exhaust pipe 5 connected to the first heat storage chamber 2, so that the gas completes heat exchange in the first heat storage chamber 2 and is then discharged. This cyclic switching ensures that the incineration process continues efficiently, and fully utilizes the heat storage and heat exchange functions of the three heat storage chambers 2, improving energy utilization and waste gas treatment efficiency.

[0034] During the operation of the device, the first and second gas pressure sensors 111 and 112 in the gas pressure monitoring assembly 11 monitor the gas pressure difference above and below each heat storage body carrier 7 and heat storage body in real time. When the gas pressure difference is abnormal, it indicates that the heat storage body in the corresponding heat storage body carrier 7 may be blocked.

[0035] Once a blockage is detected, the valve connecting the air inlet pipe 102 to the backflush pipe 101 in the backflush assembly 10 above the heat storage body carrier 7 is opened, and the exhaust pipe 5 connected to the corresponding incineration chamber 1 is also opened. High-pressure air is blown out from the nozzle 103 of the backflush pipe 101, acting on the top of the heat storage body, causing the blocked material in the heat storage body to fall into the filter 9 below the heat storage body carrier 7 under the impact of the airflow. During subsequent maintenance, the bolts between the second limiting door plate 94 of the filter 9 and the heat storage chamber 2 are unscrewed, the filter 9 is removed, the screen 92 inside the second frame 91 is cleaned to remove the collected blockage, and the filtering function is restored.

[0036] If the heat storage body still has the blockage problem after being cleaned by the back blowing and the filter 9, the bolt between the first limiting door plate 75 of the heat storage body carrier 7 and the heat storage chamber 2 is further unscrewed, the heat storage body carrier 7 and the heat storage body are taken out, and overall maintenance or replacement is carried out, so that the normal operation of the entire incinerator and the stability of the waste gas treatment effect are ensured.

[0037] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
