[0023] Furthermore, the baffle 13 forms a vertical lifting structure with the second connecting pipe 10 through the telescopic arm 12 under the action of the electric push rod 11, so that the baffle 13 is driven to rise and fall under the action of the electric push rod 11, so that the oxidized gas enters the cooling box 14 quantitatively for cooling.

This is the use process of the exhaust gas oxidation treatment device.
