Two groups of filter self-cleaning components 25 are provided, and the two groups of filter self-cleaning components 25 are equidistantly distributed in the impurity pretreatment box 23.

[0023] In the above scheme, with the assistance of the air inlet fan 22 in the first air pipe 21, the exhaust gas in the hydrogen fluoride rotary reactor body 1 enters the impurity pretreatment box 23 through the first air pipe 21, and the filtering self-cleaning component 25 in the impurity pretreatment box 23 processes the impurities in the exhaust gas.
