When the first thermometer 91 detects that the reaction temperature in the first reactor 1 is within the normal temperature range, the controller controls the first control valve 831, the second control valve 841, the fifth control valve 871, the third control valve 851, the fourth control valve 861, the sixth control valve 881, the liquid outlet regulating valve 821 and the direct connection valve 896 to close, starts the jacket liquid inlet pump 811, and realizes the circulation of the medium between the jacket 98, the jacket liquid outlet pipe 82, the circulation pipe 89 and the jacket liquid inlet pipe 81 through the operation of the jacket liquid inlet pump 811, so as to control the temperature of the jacket 98.

[0059] The control logic and principle of the reaction centrifuge device of the present invention are as follows: before centrifuging the material in the reactor 9, the mother liquid discharge valve 31, the centrifuge mother liquid outlet valve 13 and the centrifuge emptying valve 21 are first opened to form the centrifuge 4, the mother liquid tank 1 and the mother liquid pipeline 3 into a whole; then the nitrogen valve provided on the centrifuge 4 body is opened to start the inerting of the centrifuge 4; when the centrifuge 4 is inerted, the air in the centrifuge 4 is discharged by opening the emptying valve (21) on the mother liquid emptying pipe 2 to achieve the inerting of the centrifuge 4. Then, the controller determines the pressure change of the centrifuge according to the centrifuge pressure transmitter and automatically controls the centrifuge emptying valve 21. When the centrifuge speed reaches the set speed, the centrifuge feed valve 61 is opened, the bottom nitrogen valve 641 is opened, and the centrifuge feed pipe is confirmed to be unobstructed. If it is unobstructed, the bottom nitrogen valve 641 is closed; then the discharge valve 62 of the reactor 9 is opened to perform the feeding operation; the controller automatically controls the opening of the nitrogen valve 921 of the reactor 9 according to the set feed pressure; when the centrifuge material detector is triggered, the discharge valve 62 is closed and the bottom nitrogen valve 641 is opened; when the weight of the mother liquid tank reaches the set value, the discharge valve 62 is closed and the bottom nitrogen valve 641 is opened; after the feeding is completed, the bottom nitrogen valve 641 is closed and the centrifuge feed valve 61 is closed; when the centrifuge 4 enters the separation program, the centrifuge automatically increases the separation speed. When the weight change rate of the liquid storage tank 1 is less than a certain set value, the system defaults to separation completion and enters the next step of unloading operation.
