[0019] In this embodiment, the carbon dioxide intake and diversion component 204 includes a carbon dioxide reaction intake pipe 2041 and a carbon dioxide reaction diversion pipe 2042. The carbon dioxide reaction intake pipe 2041 is connected to the carbon dioxide gas pipe 108.

[0020] In this embodiment, the backblowing assembly 202 includes a backblowing main pipe 2021 and backblowing branch pipes 2022 whose number is the same as the number of carbon dioxide reaction diversion pipes 2042. The backblowing main pipe 2021 is provided with a backblowing temperature gauge 2023.
