The utility model adds a cooling part and an adsorption part, etc., so that the exhaust gas after combustion enters the exhaust duct, enters the adsorption part after being cooled by the cooling part, further removes the residual organic matter in the gas, and then is discharged from the top of the exhaust duct. Before the gas is adsorbed by the activated carbon, it is cooled first, which is conducive to the full adsorption and purification of the low-temperature gas by the activated carbon. The adsorption effect is good and the operation is relatively convenient.

[0004] However, the cooling pipe of the above device is a straight pipe, which causes the airflow to pass through too fast, affecting the cooling effect. In order to ensure the effect, the device is built too high, so that when the staff replaces the activated carbon filler, they need to climb up to operate, causing inconvenience and posing a safety hazard.

[0005] Therefore, it is necessary to invent a RTO combustion device to solve the above problems. Utility Model Content
