When the pressure in the reactor or the pipeline exceeds the set pressure of the pressure relief valve, the pressure relief valve is automatically opened, the pressure in the reactor and the pipeline is ensured to be lower than the set pressure, equipment and the pipeline are protected from accidents, and a back pressure valve is arranged on the pipeline before the heater. For maintaining a constant pressure at the outlet of the dosing pump. Under the state of unstable pressure of a pipeline or a device container, the pressure required by the pipeline can be kept, so that the dosing pump can normally output flow, the filter is a pipeline filter, the AB agent in the A agent dissolving tank 3 and the B agent dissolving tank 6 is manually treated, and the AB agent is quantitatively dosed by using a manual measuring cup.

The circuits and control involved in the present utility model are all of the prior art, and are not described in detail herein.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
