[0002] In modern waste gas treatment technologies, RTO (regenerative thermal incinerator) and zeolite rotors are relatively common waste gas treatment devices. RTO technology oxidizes combustible waste gas into corresponding oxides and water at high temperatures, and recovers the heat released during waste gas decomposition. The waste gas decomposition efficiency reaches over 99%, and the heat recovery efficiency reaches over 95%. Existing RTOs require multiple heat exchangers to fully exchange heat for the flue gas, making the entire system structure complex. Patent CN218599732U discloses a catalytic incinerator waste gas zeolite concentration rotor system, which uses a rectifier component. However, the rectification efficiency of the rectifier component is low, resulting in a large accumulation of internal flue gas, affecting heat exchange and combustion efficiency.

[0031] The burner's function is to provide the necessary heat for complete combustion.

[0032] The flue gas passes through the outer cylinder 503 and the insulation layer 502 from the air inlet 504 and enters the heat exchange zone 521 in the inner cylinder 501. The outside of the heat exchange tube 506 in the heat exchange zone 521 moves toward the burner 511 along with the guidance of the guide plate 1 507 and the guide plate 2 508. During the movement, a part of the flue gas after combustion by the burner 511 enters the inside of the heat exchange tube 506 and exchanges heat with the flue gas to be burned in the heat exchange zone 521, so that the temperature of the flue gas to be burned increases. Then, it passes through the outer edge of the partition plate 2 509 and enters the air intake zone 522 between the inner cylinder 501 and the isolation cylinder 510. At the end of the isolation cylinder 510, it is connected to the Venturi section 2 of the Venturi assembly. After the gas flow rate is increased in the Venturi section 2, it enters the combustion zone, so that the flue gas can enter the combustion zone 524 and be fully burned within the combustion range. After the flue gas is burned, it enters the transition zone 523, and then passes through the second rectifier and acceleration of the Venturi section of the Venturi component in the transition zone 523 before entering the heat exchange tube 506. After heat exchange with the newly entered flue gas to be burned in the heat exchange tube 506, it enters the exhaust zone 520 from the other end of the heat exchange tube 506 and is discharged through the exhaust port 514 of the exhaust zone 520. Another part of the flue gas enters the straight exhaust pipe 512 through the rectification of the center hole in the center of the straight exhaust component 51603. A regulating valve 513 is installed at the end of the exhaust pipe, and the exhaust volume of the straight exhaust pipe 512 can be controlled by adjusting the opening of the regulating valve 513.
