[0023] Example:

[0024] See also Figure 1-3 The present embodiment provides a high-efficiency green multilayer reactor system integrating liquid-liquid mixing reaction and stirring, which comprises a three-layer stirring reaction system 1 and a loop system 2. The three-layer stirring reaction system is used to promote mixing and mass transfer in the reaction process, and improve the reaction rate and uniformity; the loop system is used to realize the synchronous reaction and stirring process, and improve the reaction efficiency and stirring and mixing uniformity.

[0025] Specifically, the three-layer stirring reaction system 1 is the main structure for liquid fluid to participate in the reaction, including a stirring tank body 101, a hydraulic screw 102, a motor 103, a stirring shaft 104, an impeller 105, a planetary reducer 106, a stirring blade 107, a filter screen plate 108 and a single cone spiral belt 109.

[0026] The interior of the stirring kettle body 101 is divided into three layers of stirring reaction space from top to bottom by two filter screens 108; among them, the upper stirring reaction space and the middle stirring reaction space on the stirring kettle body 101 are cylindrical structures, and the lower stirring reaction space is a conical cylindrical structure.

[0027] The hydraulic screw 102 is installed on the upper part of the stirring tank body 101, and the fluid enters the stirring tank body 101 through the internal turbine flow channel.

[0028] The motor 103 is arranged on the top of the stirring tank body 101, and the output end of the motor 103 is connected to the stirring shaft 104; the stirring shaft 104 is arranged through the three layers of stirring reaction space.

[0029] The impeller 105 is mounted on the stirring shaft 104 and is located in the upper stirring reaction space.

[0030] The planetary reducer 106 is placed on a filter screen plate 108 , which is coaxially arranged with the stirring shaft 104 .

[0031] The stirring blade 107 and the single cone spiral belt 108 are both installed on the stirring shaft 104 and are respectively located in the middle stirring reaction space and the lower stirring reaction space.

[0032] The filter screen plate 108 is concentric with the stirring shaft 104 .

[0033] A truncated cone-shaped shell 110 coaxial with the stirring shaft 104 is arranged in the upper stirring reaction space, and the smaller end of the truncated cone-shaped shell 110 is arranged downward to form a flow channel structure with a gradually decreasing size.

[0034] Specifically, the loop system 2 includes a feed pipe 201 , a discharge pipe 202 , a one-way valve 203 , a flow meter 204 , a pressure pipe 205 and a filter 206 .

[0035] The feed port 201 is connected to the inlet of the hydraulic screw 102, the discharge pipe 202 is connected to the bottom of the stirring tank 101, the one-way valve 203 is connected to the discharge pipe 202, the flow meter 204 is connected to the one-way valve 203 through the pressure pipe 205, the filter 206 is connected to the flow meter 204 through the pressure pipe 205, and the final outlet end is connected to the inlet end of the hydraulic screw 102.

[0036] The working principle of the system in this embodiment is as follows:

[0037] Through the hydraulic screw 102, the material enters the upper stirring reaction space through the turbine flow channel inside the hydraulic screw 102, thereby increasing the pressurization of the liquid phase fluid and increasing the kinetic energy. The fast rotation of the impeller 105 drives the liquid phase fluid to move quickly, thereby improving the reaction efficiency. A planetary reducer 106 is arranged below the impeller 105, and the speed converter of its gear is used to reduce the rotation speed of the high-speed rotating impeller 105 and transmit it to the stirring blades 107 in the middle layer stirring reaction space.

[0038] In the upper stirring reaction space, the flow channel gradually shrinks, and the flow channel in the middle stirring reaction space expands. Based on the principle of the Venturi ejector, the liquid phase fluid is introduced into the middle reaction space, and the negative pressure realizes the accelerated flow of the liquid phase, thereby promoting the desired reaction. The stirring blades 107 in the middle stirring reaction space and the single cone spiral ribbon 109 in the lower stirring reaction space move, continuing to drive the fluid to stir and react, thereby improving the material reaction efficiency.

[0039] In the loop system 2, the feed port 201 is connected to one inlet end of the hydraulic screw 102, and the unmixed liquid phase fluid flows out from the outlet of the stirring tank body 101, is connected to the other inlet end of the hydraulic screw 102 through the discharge pipe 202 and the pressure pipe 205, and flows back into the stirring tank body 101 to continue the reaction, thereby improving the uniformity of the material reaction mixing.

[0041] In this embodiment, in the first layer of the stirring reaction space, the turbine flow channel based on the hydraulic screw 102 is used to increase the pressure of the feed, and the high-speed rotation of the impeller 105 realizes the mixing reaction of the feed; in the second layer of the stirring reaction space, the cylinder flow channel is expanded in imitation of the Venturi ejector structure to achieve liquid phase acceleration, and the stirring reaction is continued by the stirring blades 107; in the third layer of the stirring reaction space, the conical cylinder is convenient for discharging, and the single conical spiral belt 109 continues to drive the material for stirring reaction.

[0042] At the same time, the loop system 2 transports the materials that are not fully stirred and mixed to the feed end, thereby improving the uniformity of the reaction.
