That is, the present embodiment uses the continuous phase separation tank 31 to achieve continuous stratification by utilizing the material density difference, without the need for additional mechanical devices, and the stratification is fast and accurate, greatly improving the production efficiency of iprodione.

The three-way pipe is provided to ensure the normal use of the wastewater recovery pipeline and the wastewater reuse pipeline and to prevent mutual interference.

[0047] It needs to be further explained that, as shown in Figure 2 、 Figure 3 and Figure 4 , the production device of the embodiment further comprises a tail gas discharge system 10 for discharging tail gas in the continuous phase separation tank 31 and the stirring reaction tank 11. The tail gas discharge system 10 comprises a first tail gas output port 101 provided on the stirring reaction tank 11 and a second tail gas output port 102 provided on the continuous phase separation tank 31; the first tail gas output port 101 and the second tail gas output port 102 are both communicated with an external tail gas removal system pipeline.

[0049] Specifically, the data acquisition modules comprise a plurality of liquid level sensors provided in the continuous phase separation tank 31 and the stirring reaction tank 11; the liquid level sensors in the stirring reaction tank 11 are used to detect the liquid level information in the stirring reaction tank 11; the liquid level sensors in the continuous phase separation tank 31 are used to detect the liquid level information of the solution after reaction, the liquid level information of the organic phase after phase separation and the liquid level information of the water phase.
