[0037] In one embodiment, this application proposes a uniform feed mixing reactor, including a reaction vessel 101, wherein the reaction vessel 101 is provided with a reaction chamber 102, and the reaction media are mixed in the reaction chamber 102. After the two reaction media are mixed and reacted in the reaction chamber 102, the product is discharged through a reaction vessel outlet pipe 103 provided with the reaction vessel.
[0038] A first reaction medium delivery mechanism and a second reaction medium delivery mechanism are installed in the reaction chamber 102. The first reaction medium is delivered into the reaction chamber 102 through the first reaction medium delivery mechanism, and the second reaction medium is delivered into the reaction chamber 102 through the second reaction medium delivery mechanism. In this embodiment, both the first reaction medium and the second reaction medium are liquids.
[0039] The first reaction medium conveying mechanism is provided with multiple sets of first outlets, and the second reaction medium conveying mechanism is provided with multiple sets of second outlets. The arrangement of the first and second outlets simultaneously satisfies the following conditions: (1) Each set of first outlets and each set of second outlets includes multiple outlets arranged along the axial direction of the reaction tank; (2) In the circumferential direction of the reaction tank 101, each set of first outlets and each set of second outlets are arranged alternately; (3) ... Figure 4 , 6 As shown, the distance between the first outlet and the center line of the reaction tank is R1, and the distance between the second outlet and the center line of the reaction tank is R2, where R1 = (0.98~1.02)R2. This arrangement facilitates reactor manufacturing and enables uniform feeding and mixing of the two reaction media upon entering the reaction tank, while saving stirring time.
[0040] For the implementation of the first outlet and the second outlet, please refer to the following embodiments.
[0041] Example 1
[0042] like Figure 1-4 As shown, the first reaction medium conveying mechanism includes a first annular pipe 201, which is connected to a first inlet pipe 202 and multiple first branch pipes 203. The first reaction medium can be conveyed into the first annular pipe 201 through the first inlet pipe 202, and then enter each of the first branch pipes 203 through the first annular pipe 201. The multiple first branch pipes 203 are evenly arranged around the circumference of the reaction tank 101, with a gap between each first branch pipe 203. The first branch pipes 203 extend axially along the reaction tank 101, and each first branch pipe 203 has a first outlet (not shown in the figure) provided at intervals along the extension direction of the first branch pipe 203.
[0043] Similarly, the second reaction medium conveying mechanism includes a second annular pipe 301, which is connected to a second inlet pipe 302 and multiple second branch pipes 303. The second reaction medium can be conveyed into the second annular pipe 301 through the second inlet pipe 302, and then into each of the second branch pipes 303 through the second annular pipe 301. The multiple second branch pipes 303 are evenly arranged around the circumference of the reaction tank 101, with a gap between each second branch pipe 303. Figure 4 As shown, the first branch pipe 203 and the second branch pipe 303 are arranged alternately. The second branch pipe 303 extends axially along the reaction vessel 101, and a second outlet 104 is provided alternately on each second branch pipe 303 along the extension direction of the second branch pipe 303.
[0044] To ensure that the distances from the first outlet to the centerline of the reactor are approximately equal to those from the second outlet, the distances from the first branch pipe 203 to the centerline of the reactor must also be approximately equal to those from the second branch pipe 303. As an optional implementation, the diameter D1 of the first annular pipe 201 is larger than the diameter D2 of the second annular pipe 301. Furthermore, the second branch pipe 303 is connected to the second annular pipe 301 via a transition pipe 303-1. This ensures that the distances from the first branch pipe 203 to the centerline of the reactor are also approximately equal to those from the second branch pipe 303.
[0045] As an optional embodiment, a heat exchange mechanism can also be provided to utilize the heat generated during the mixing and reaction of the two reaction media. Specifically, such as Figure 1As shown, an outer tank 401 is installed on the outside of the reaction tank 101, and a heat exchange cavity 402 is formed between the inner wall of the outer tank 401 and the outer wall of the reaction tank 101. The outer tank 401 is provided with a heat exchange medium inlet 403 and a heat exchange medium outlet 404, which are connected to the heat exchange cavity 402. The heat exchange medium enters the heat exchange cavity 402 through the heat exchange medium inlet 403. The heat generated by the reaction in the reaction cavity 102 is exchanged with the heat exchange medium through the tank body of the reflective tank 101, and the heat exchange medium flows out through the heat exchange medium outlet 404 after heat exchange.
[0046] Preferably, the reaction vessel outlet pipe 103 is located at the bottom of the reaction vessel 101, while the heat exchange medium inlet 403 is located at the bottom and the heat exchange medium outlet 404 is located at the top, thereby improving the heat exchange efficiency.
[0047] Example 2
[0048] like Figure 5-6 As shown, a first cylinder 501, a second cylinder 502, and a third cylinder 503 are sequentially installed from the outside to the inside within the reaction chamber 102. The bottoms of the first cylinder 501, the second cylinder 502, and the third cylinder 503 are sealed to the inner wall of the reaction chamber 102, thereby forming a first flow channel 506 between the first cylinder 501 and the second cylinder 502, and a second flow channel 507 between the second cylinder 502 and the third cylinder 503. Both the first flow channel 506 and the second flow channel 507 are provided with inlets, through which the first reaction medium and the second reaction medium enter the first flow channel 506 and the second flow channel 507, respectively.
[0049] The second outlet 104 is located on the third cylinder 503 and is connected to the second flow channel 507. The second reaction medium in the second flow channel 507 can enter the reaction chamber 102 through the second outlet 104. Multiple sets of second outlets 104 are provided on the third cylinder 503, with each set of second outlets 104 arranged circumferentially around the third cylinder 503. Each outlet in each set of second outlets 104 is arranged axially around the third cylinder 503.
[0050] A connecting pipe 504 is installed between the second cylinder 502 and the third cylinder 503, and a transition channel 508 is formed inside the connecting pipe 504. A first outlet 105 is located on the third cylinder 503 and communicates with the transition channel 508. A transition outlet 505 is provided on the second cylinder 502, connecting the first channel 506 and the transition channel 508. The first reaction medium in the first channel 506 enters the transition channel 508 through the transition outlet 506, and then flows into the reaction chamber 102 through the first outlet 105. Multiple sets of first outlets 105 are provided on the third cylinder 503, with each set of first outlets 105 arranged alternately along the circumference of the third cylinder 503. Each outlet in each set of first outlets 105 is arranged alternately along the axial direction of the third cylinder 503.
[0051] In the circumference of the third cylinder 503, the first outlet 105 and the second outlet 104 are arranged alternately, so that the two reaction media can be fed and mixed evenly when they enter the reaction tank, while saving stirring time.
[0052] As an optional embodiment, a heat exchanger is installed inside the third cylinder 503, thereby utilizing the heat generated during the mixing and reaction of the two reaction media in the reaction chamber 102 for heat exchange. Specifically, as Figure 6-7 As shown, the heat exchanger includes an upper annular tube 405 and a lower annular tube 406, which are connected by multiple vertical tubes 407 arranged in a ring. One of the upper annular tube 405 and the lower annular tube 406 is connected to the heat exchange medium inlet, and the other is connected to the heat exchange medium outlet. The heat exchange medium enters from the heat exchange medium inlet and flows out from the heat exchange medium outlet.
[0053] As an optional embodiment, in order to further improve the reaction rate, a stirring blade and a driving mechanism for driving the stirring blade to rotate can also be provided. The driving mechanism can drive the stirring blade to rotate, thereby stirring the first reaction medium and the second reaction medium in the reaction chamber 102 through the stirring blade.
[0054] As an optional implementation, the diameters of the first outlet and the second outlet are 0.05 mm to 0.15 mm, for example, 0.1 mm, so that the flow rates of the first reaction medium and the second reaction medium can be controlled, which is beneficial to the uniform mixing and reaction of the two reaction media.
[0055] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
