The VOC incineration operation device 1 includes, in addition to the first combustion furnace 11 and the second combustion furnace 13, a first exhaust valve 11a, a first clean air valve 11b, a second exhaust valve 13a, and a second clean air valve 13b. The first heat discharge pipe 11c, the second heat discharge pipe 13c, the exhaust pipe 12, the clean air pipe 14, and the blower 16. The exhaust gas device 3 is treated to include an exhaust gas treatment device 31, a first air valve 33, and a second air valve 35.

The exhaust pipe 12 is for conveying the VOC to be incinerated, and the clean air pipe 14 is for conveying the clean gas after the VOC is destroyed. The first exhaust valve 11a is connected between the first combustion furnace 11 and the exhaust pipe 12, and the first clean gas valve 11b is connected between the first combustion furnace 11 and the clean air pipe 14. The second exhaust valve 13a is connected between the second combustion furnace 13 and the exhaust pipe 12, and the second clean gas valve 13b is connected between the second combustion furnace 13 and the clean air pipe 14. The first heat discharge pipe 11c is connected to the upper end of the first combustion furnace 11 for conveying the high-temperature clean gas generated by the VOC which has been destroyed in the furnace of the first combustion furnace 11 and transporting it outward. The second heat discharge pipe 13c is connected to the upper end of the second combustion furnace 13 for transporting the high-temperature clean gas generated by the VOC which has been destroyed in the furnace of the second combustion furnace 13 to the outside.

In operation, the fan 16 can form a negative pressure at the A position of the discharge pipe 18, and therefore the flow direction of the VOC incineration working device 1 will flow toward the A position.

Please refer to Fig. 1, firstly, the first combustion furnace 11 is first used as a reaction furnace, and the main function of the reaction furnace is to incinerate the VOC, so that the VOC is destroyed and converted into a high-temperature clean gas.
