[0040] Reference Figures 1 to 17, the accompanying drawings illustrate three types of reactors, among which the reactor includes a reactor body 100 and a heat exchange structure 200. The reactor body 100 is provided with a reaction tube cavity 110, a feed port 120 and a discharge port 130, the feed port 120 is connected to one end of the reaction tube cavity 110 along the length direction, and the discharge port 130 is connected to the other end of the reaction tube cavity 110 along the length direction. The heat exchange structure 200 is arranged in the reactor body 100, and the heat exchange structure 200 includes a plurality of heat exchange plates 210 arranged in the reaction tube cavity 110 and arranged at intervals along the length direction of the reaction tube cavity 110, and the heat exchange plates 210 extend along the radial direction of the reaction tube cavity 110, and the heat exchange plates 210 are used to make the material in the reaction tube cavity 110 form a tortuous flow. In the embodiment shown in the accompanying drawings, the length direction of the reaction tube cavity 110 is shown by the double arrow A in the figure, and the radial direction of the reaction tube cavity 110 is the direction of the vertical arrow A.

[0041] During production, the material is input into one end of the reaction tube cavity 110 through the feed port 120, and the material will move along the reaction tube cavity 110 to the other end, and the product after the material mixing reaction is output through the discharge port 130, thereby forming a continuous production. In the above process, the heat exchange plate 210 of the heat exchange structure 200 forms an obstacle to the material, so that the material forms a tortuous flow between the multiple heat exchange plates 210, and the heat exchange plate 210 also performs heat exchange on the tortuous flow of the material. The above reactor adopts the setting of multiple heat exchange plates 210, the heat exchange area is large, and the material can form a tortuous flow between the heat exchange plates 210, the heat exchange efficiency is high, and the mixing effect between the materials is good, thereby improving the production efficiency.

[0042] In each embodiment shown in the drawings, the heat exchange plate 210 is provided with a hollow channel 211, and the heat exchange structure 200 also includes a connecting channel connecting the hollow channels 211 of each heat exchange plate 210, and the connecting channel and each hollow channel 211 together constitute a heat exchange flow channel, and the reactor body 100 or the heat exchange structure 200 is provided with a heat exchange medium inlet and a heat exchange medium outlet connected to the heat exchange flow channel. With the above structure, the heat exchange plate 210 can exchange heat with the material by inputting a heat exchange medium into the heat exchange flow channel. The above heat exchange medium can be, for example, water, oil or other fluids capable of heat exchange.

[0043] It is conceivable that, in certain embodiments, the heat exchange plate 210 may also have heat exchange capabilities other than limited to the above-mentioned structure, for example, it may be made of a material with good heat dissipation and conduct heat outwardly through a heat-conducting structure; it is understandable that in this field, there are many specific implementations of the heat exchange plate 210, and those skilled in the art may reasonably configure its structure according to actual conditions without being limited to the above-mentioned implementations.

[0044] In the embodiment, several feed ports 120 may be provided, and different materials may be input simultaneously; of course, it is conceivable that in certain embodiments, if some premixing structures are additionally adopted, only a single feed port 120 may be provided.

[0045] In each embodiment shown in the drawings, the reactor further includes a stirring assembly 300, which is disposed on the reactor body 100. The stirring assembly 300 includes a stirring shaft 310, a stirring blade 320, and a rotary driver 330. The stirring shaft 310 is disposed along the length direction of the reaction lumen 110 and extends into the reaction lumen 110. The stirring blade 320 is disposed on the stirring shaft 310, and the rotary driver 330 is used to drive the stirring shaft 310 to rotate. When the rotary driver 330 drives the stirring shaft 310 to rotate, the mixed material can be stirred by the stirring blade 320.

[0046] Reference Figures 1 to 6 , which is one of the implementation structures of the present invention. In this embodiment, the heat exchange plate 210 of the heat exchange structure 200 is disc-shaped, and the heat exchange plate 210 is provided with a central through hole 212. The stirring shaft 310 is provided through the central through hole 212 of each heat exchange plate 210. The heat exchange plate 210 is divided into a larger plate and a smaller plate. The diameter of the larger plate is larger than that of the smaller plate. The diameter of the central through hole 212 of the larger plate is larger than that of the central through hole 212 of the smaller plate. The larger plate and the smaller plate are arranged alternately. The outer periphery of the smaller plate and the cavity wall of the reaction tube cavity 110 form an outer peripheral channel 401 connecting the two sides of the smaller plate. The hole wall of the central through hole 212 of the larger plate and the stirring shaft 310 form an inner channel 402 connecting the two sides of the larger plate. With the above structure, when the material encounters a smaller plate in the process of moving from one end of the reaction tube cavity 110 to the other end, it can be stopped and guided to the outer periphery of the smaller plate, and the material continues to flow forward through the outer peripheral channel 401. After passing through the peripheral channel 401, the material can be stopped by the larger plate and guided to the middle perforation 212 of the larger plate, and continue to flow forward through the inner channel 402; this is repeated, and during the forward movement of the material, the material can form a tortuous flow that first moves radially outward and then radially inward, and so on, which has a better material mixing effect and more sufficient heat exchange. The flow mode of the above-mentioned material can be referred to Figure 2 As indicated by the arrow in .

[0047] exist Figures 1 to 6In the embodiment of the present invention, the heat exchange structure 200 includes a heat exchange medium input pipe 220 and a heat exchange medium output pipe 230. The two ends of the heat exchange plate 210 are respectively fixed to the heat exchange medium input pipe 220 and the heat exchange medium output pipe 230. The heat exchange medium input pipe 220 and the heat exchange medium output pipe 230 form an assembly with the heat exchange plate 210 and are accommodated together in the reaction tube cavity 110. The tube cavity of the heat exchange medium input pipe 220 and the tube cavity of the heat exchange medium output pipe 230 are respectively connected to the two ends of the hollow channel 211 of the heat exchange plate 210. The heat exchange medium input pipe 220 and the heat exchange medium output pipe 230 are respectively provided with an input port 221 and an output port 231. With the above structure, through the arrangement of the heat exchange medium input pipe 220 and the heat exchange medium output pipe 230, each heat exchange plate 210 can be connected together to form an assembly, which is easy to install and has a stable overall structure. When in use, the heat exchange medium can be input through the input port 221, and after exchanging heat through each heat exchange plate 210, it can be output through the output port 231. The flow mode of the heat exchange medium inside the heat exchange structure 200 can be seen in Figure 4 As indicated by the arrow in .

[0048] In the embodiment, the plate surface of the heat exchange plate 210 can be set to a wave shape, so that the heat exchange area is larger. Of course, it is conceivable that the plate surface of the heat exchange plate 210 can also be set to a plane or other suitable shape, which can be configured according to actual conditions.

[0049] Reference Figures 7 to 12 , which is one of the implementation structures of the present invention. In this embodiment, the heat exchange structure 200 includes two subassemblies 240, and the subassembly 240 includes a row of heat exchange plates 210 and is provided with a heat exchange medium input pipe 220 and a heat exchange medium output pipe 230. The two ends of the heat exchange plate 210 are respectively fixed to the heat exchange medium input pipe 220 and the heat exchange medium output pipe 230. The lumen of the heat exchange medium input pipe 220 and the lumen of the heat exchange medium output pipe 230 are respectively connected to the two ends of the hollow channel 211 of each heat exchange plate 210. The heat exchange medium input pipe 220 and the heat exchange medium output pipe 230 are respectively provided with an input port 221 and an output port 231; each row of heat exchange plates 210 of each subassembly 240 is arranged around the outer peripheral side of the stirring shaft 310. In the embodiment shown in the drawings, the heat exchange structure 200 is divided into two subassemblies 240. It is conceivable that in some embodiments, the heat exchange structure 200 can also be divided into more than two subassemblies 240, which can be specifically configured according to actual conditions. In the above structure, each subassembly 240 is formed with an independent heat exchange flow channel, and the heat exchange medium can be input and output through the respective heat exchange medium input pipe 220 and heat exchange medium output pipe 230, thereby realizing the corresponding heat exchange function. The flow mode of the heat exchange medium in the subassembly 240 can be referred to Fig.11 As indicated by the arrow in .

[0050] By adopting the above structure, the heat exchange structure 200 is divided into at least two sub-assemblies 240. Compared with the single integral assembly, the heat exchange medium flow rate of each sub-assembly 240 is relatively small, and the diameters of the heat exchange medium input pipe 220 and the heat exchange medium output pipe 230 of the sub-assembly 240 are allowed to be made smaller, which is conducive to reducing the volume. In addition, compared with the heat exchange structure 200 adopting a single integral assembly, the design of the sub-assembly 240 does not require the stirring shaft 310 to be inserted into each heat exchange plate 210, and the sub-assembly 240 can be conveniently combined with the stirring shaft 310, which is conducive to simplifying the assembly of the reactor.

[0051] exist Figures 7 to 12 In the illustrated embodiment, the outer peripheral surface of the heat exchange plate 210 includes a tube cavity opposite surface 213 and a stirring shaft opposite surface 214, the tube cavity opposite surface 213 is adapted to the tube wall shape of the reaction tube cavity 110, the heat exchange plate 210 of the subassembly 240 is divided into a larger plate and a smaller plate, the tube cavity opposite surface 213 of the larger plate is closer to the tube wall of the reaction tube cavity 110 than the tube cavity opposite surface 213 of the smaller plate, the larger plates and the smaller plates are arranged alternately, and a peripheral channel 401 connecting the two sides of the smaller plate is formed between the tube cavity opposite surface 213 of the smaller plate and the cavity wall of the reaction tube cavity 110, and between the heat exchange plates 210 of different subassemblies 240, the larger plates are opposite to each other one by one, and the smaller plates are opposite to each other one by one, and an inner channel 402 is formed between the stirring shaft opposite surfaces 214 of the two corresponding larger plates. With the above structure, similar to the first embodiment of the present invention, when the material flows from one end to the other end of the reaction tube cavity 110, the material alternately flows between the outer peripheral channel 401 and the inner channel 402, so that the material can form a tortuous flow from radially outward to radially inward and then to radially outward repeatedly, and the mixing effect and heat exchange effect are good. The above flow mode of the material can be referred to Figure 8 As indicated by the arrow in .

[0052] exist Figures 1 to 6 , Figures 7 to 12 In the two embodiments, the reactor body 100 includes an inner shell 140 and an outer shell 150, the reaction tube cavity 110 is arranged in the inner shell 140, and the outer shell 150 and the inner shell 140 are enclosed to form an outer heat exchange channel, and the outer shell 150 is provided with an inlet 151 and an outlet 152 connected to the outer heat exchange channel. The heat exchange medium can be input into the outer heat exchange channel through the inlet 151 to exchange heat of the material, and the heat exchange medium that has completed the heat exchange can be output through the outlet 152, so that the heat exchange of the material can be carried out on the outer peripheral side of the reaction tube cavity 110, further improving the heat exchange effect.

In the above structure, the inner shell 140 extends inward to form the heat exchange plate 210, and the heat exchange medium flow channel is formed between the outer shell 150 and the inner shell 140. The heat exchange medium can flow through the inner side of the heat exchange plate 210 through the inlet 151, thereby realizing its heat exchange function. The above structure is simple, and there is no need to install a heat exchange plate group in the reaction tube cavity 110, which is easy to produce and implement. The flow mode of the heat exchange medium in the above heat exchange medium flow channel can be referred to Fig.17 As indicated by the arrow in .

The flow mode of the above-mentioned materials can be referred to Fig.14 As indicated by the arrow in .

[0055] In some implementations, such as Figures 1 to 6 In the illustrated embodiment, a shearing disk 340 is provided at one end of the stirring shaft 310 near the feed port 120.

The shearing pieces 342 are arranged along the circumference of the reaction lumen 110 and are provided on the four edges of the fixed plate 341. By providing the shearing disk 340, the material can be pre-sheared and mixed in the front section of the reaction lumen 110, and the mixing effect is better with the mixing of the stirring paddle in the rear section.
