[0022] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The present invention provides a static silicon carbide tubular reactor through improvement. The technical solution of the present invention is:

[0024] like Figure 1-Figure 3As shown, a static silicon carbide tubular reactor comprises an outer shell 1, which is a stainless steel tube. Two mounting plates 2 and four support blocks 3 are fixedly connected to the outer shell 1. The four support blocks 3 are fixedly connected to an inner tube 4. The inner tube 4 is a corrosion-resistant silicon carbide tube that can withstand chemical corrosion from strong acids and alkalis, and has strong thermal conductivity and can quickly conduct the reaction heat to the outer liquid guide tube 63. The two mounting plates 2 are respectively fixedly connected to a sealing gasket 7. A reaction component 5 and a heat-conducting component 6 are provided in the outer shell 1. The reaction component 5 includes a feed port 51, a filter screen 52, a silicon carbide ball 53, a stirring blade 54 and a discharge port 55. The feed port 51 is opened on the inner tube 4, and the two filter screens 52 are fixedly connected. It is connected to the inner tube 4, the filter screen 52 is a polytetrafluoroethylene screen, and multiple silicon carbide balls 53 are arranged in the inner tube 4. The silicon carbide balls 53 are located between the two filter screens 52. The stirring blade 54 is rotatably connected to the inner tube 4. The discharge port 55 is opened on the inner tube 4. The heat conduction component 6 includes a liquid inlet 61, a liquid outlet 62, a liquid guide tube 63, a fixed sleeve 64 and a three-way pipe 66. The liquid inlet 61 is opened on the outer shell 1, and the liquid outlet 62 is opened on the outer shell 1. The two ends of the liquid guide tube 63 are respectively fixedly connected to the liquid inlet 61 and the liquid outlet 62. The two fixed sleeves 64 are respectively fixedly connected to the liquid inlet 61 and the liquid outlet 62. The two three-way pipes 66 are respectively provided on the two fixed sleeves 64.

[0025] Further, such as Figure 1-Figure 3 As shown, the heat-conducting component 6 also includes a fixing ring 65 and a connecting sleeve 67. The two fixing rings 65 are fixedly connected to the two fixing sleeves 64 respectively. The two tee pipes 66 are slidably connected in the two fixing rings 65 respectively. The two connecting sleeves 67 are fixedly connected to the two tee pipes 66 respectively. The connecting sleeve 67 is located at the top of the tee pipe 66. The diameter of the tee pipe 66 is smaller than the inner wall diameter of the fixing sleeve 64.

[0026] Further, such as Figure 2 and Figure 3 As shown, the heat-conducting component 6 also includes a connecting plate 68 and a spring 1 69. The two connecting plates 68 are fixedly connected to the two tee pipes 66 respectively. The two ends of the multiple springs 1 69 are fixedly connected to the two fixing rings 65 and the two connecting plates 68 respectively. The springs 1 69 are distributed in a circular array with the center of the tee pipe 66 as the center of the circle.

[0027] Further, such as Figure 2 and Figure 3 As shown, the heat-conducting component 6 also includes a rubber plug 610 and a groove 611. The two rubber plugs 610 are fixedly connected to the two three-way pipes 66 respectively. The rubber plug 610 is located at the bottom of the three-way pipe 66. The diameter of the rubber plug 610 is consistent with the inner wall diameter of the fixing ring 65. Four grooves 611 are respectively opened on the two fixing rings 65.

[0028] Further, such as Figure 2 and Figure 3As shown, the heat-conducting component 6 also includes a rotating block 612 and a spring 2 613. The four rotating blocks 612 are respectively rotatably connected to the two connecting sleeves 67. The cross-section of the rotating block 612 on the side away from the connecting sleeve 67 is triangular. The two ends of the multiple springs 2 613 are respectively fixedly connected to the two three-way pipes 66 and the four rotating blocks 612.

[0029] Further, such as Figure 2 As shown, the heat conducting component 6 further includes a through hole 614 , and two through holes 614 are respectively provided on the two fixing sleeves 64 , one through hole 614 is located directly below the liquid inlet 61 , and the other through hole 614 is located directly above the liquid outlet 62 .

[0030] The specific working method is: the reaction raw materials are put into the inner tube 4 through the feed port 51. The inner tube 4 is divided into two sections, the front half is a static mixing zone of silicon carbide balls 53, and the back half is a static mixing zone of polytetrafluoroethylene sk blades, so that the reaction raw materials are fully stirred. Finally, the reaction raw materials are discharged through the discharge port 55. During this period, it is necessary to use the heat conduction component 6 to cool and dissipate heat to the inner tube 4. First, press the connecting sleeve 67 to move the connecting sleeve 67 toward the direction of the fixed ring 65, driving the rotating block 612 to move. When the rotating block 612 is embedded in the groove 611, due to the action of the spring 2 613, the rotating block 612 is fixed in the groove 611. At this time, the tee pipe 66 moves with the connecting sleeve 67, and the tail end of the tee pipe 66 enters the fixed sleeve 64, so that the tee pipe 66, the fixed sleeve 64 and the liquid inlet 61 are connected, and the external pipeline is inserted In the connecting sleeve 67, the heat exchange liquid is injected into the tee pipe 66 through the external pipe, flows into the liquid inlet 61 along the tee pipe 66, and then flows into the liquid guide pipe 63 from the liquid inlet 61. Since the liquid guide pipe 63 is wrapped around the inner tube 4, the liquid guide pipe 63 can absorb the heat on the inner tube 4, thereby causing the inner tube 4 to have a cooling effect. After the reaction is completed, the external pipe is removed, and the rotating block 612 is pressed to rotate it in the direction of the tee pipe 66. When the rotating block 612 is parallel to the groove 611, under the action of the spring 1 69, the tee pipe 66 moves in the direction away from the fixed sleeve 64, and the tail end of the tee pipe 66 enters the fixed ring 65 as it moves, so that the tee pipe 66 and the fixed sleeve 64 are no longer connected, and the liquid guide pipe 63 is isolated from the outside world, which can effectively prevent dust from entering the interior of the liquid guide pipe 63 and clogging the liquid guide pipe 63.

Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
