The second connection port 6 is usually closed and can only be opened after the reaction in the reaction tank 1 is completed.

[0036] Refer to Figure 1 and Figure 3, on both sides of the top of the outer wall of the reaction tank 1, support plates 8 are fixedly connected. On the top of the support plates 8, a reaction reagent tank 9 is fixedly connected. The bottom of the reaction reagent tank 9 penetrates and is fixedly connected with a connecting pipe 10, and the connecting pipe 10 penetrates and is fixedly connected to the middle of the inner wall of the support plate 8. The bottom of the connecting pipe 10 penetrates and is fixedly connected with a spraying disc 11.
