[0001] The utility model relates to the technical field of chemical equipment, in particular to a tubular reactor. Background Art

[0002] A tubular reactor is a continuous operation reactor in the shape of a tube with a very large length-diameter ratio. Such a reactor can be very long. For example, the reactor tube for propylene dimerization is measured in kilometers. The structure of the reactor can be a single tube or multiple tubes in parallel.

[0003] For example, a tubular reactor is disclosed in CN220478839U, which includes a bottom plate. Two columns are fixedly connected to the upper side of the bottom plate. A tubular reactor body is arranged above the bottom plate, and further includes: a plurality of groups of support components, which are located above the bottom plate and are rotationally symmetric in a plurality of groups; a plurality of groups of limiting components, which are located above the bottom plate and are located below the support components.

[0004] The above-mentioned supports different pipes of the tubular reactor body respectively by setting support components, which is convenient for personnel to disassemble and repair different pipes. However, during use, it is found that when one of the tubular reactor bodies is damaged and needs to be disassembled, the reaction liquid in the tubular reactor body to be disassembled and other tubular reactor bodies cannot be drained completely, resulting in a large amount of reaction liquid flowing out during the disassembly process, which not only causes waste of reaction liquid, but also makes the working environment bad. Summary of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a tubular reactor to solve the problem that a large amount of reaction liquid flows out of the tubular reactor body during the disassembly process in the prior art, which not only causes waste of reaction liquid, but also makes the working environment bad.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A tubular reactor includes a plurality of tubular reactor bodies connected in sequence. The connecting ears formed at both ends of each tubular reactor body extend to one side to form an installation part. An adjustable sealing part for sealing or unsealing the opening at the corresponding end of the tubular reactor body is arranged between the installation part and the corresponding connecting ear.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] When this tubular reactor is in use, each adjustable sealing part relieves the seal of the opening at the corresponding end of the corresponding tubular reactor body, and the multiple tubular reactor bodies are connected in sequence to provide a reaction site for the reaction liquid; when it is necessary to disassemble one of the tubular reactor bodies, first adjust the adjustable sealing parts at both ends of the tubular reactor body to be disassembled and the adjustable sealing parts at the end of the tubular reactor body connected to the tubular reactor body to be disassembled, so that the adjustable sealing parts seal the openings at the ends of the corresponding tubular reactor bodies, and then the tubular reactor body to be disassembled can be disassembled, avoiding the outflow of the reaction liquid in the disassembled tubular reactor body and other tubular reactor bodies, reducing the waste of the reaction liquid, and ensuring the cleanliness of the working environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The present invention will be further described in detail below through specific embodiments:

[0015] The existing tubular reactor realizes the support of different pipelines of the tubular reactor body 1 respectively by setting a support assembly, which is convenient for personnel to disassemble and repair different pipelines; however, it is found during use that one of the tubular reactor bodies 1 is damaged and needs to be disassembled. Since the reaction liquid in the tubular reactor body 1 to be disassembled and other tubular reactor bodies 1 cannot be drained completely, a large amount of reaction liquid flows out during the disassembly process, which not only causes waste of the reaction liquid, but also makes the working environment poor. To solve this problem, such as Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of the utility model provides a tubular reactor, which includes a plurality of tubular reactor bodies 1 (not shown in the attached drawings) connected in sequence. Connection ears 2 are formed at both ends of each tubular reactor body 1 and extend to one side thereof to form an installation part 3. An adjustable sealing part 5 for sealing or unsealing an opening 4 at the corresponding end of the tubular reactor body 1 is arranged between the installation part 3 and the corresponding connection ear 2.

[0016] When this tubular reactor is in use, each adjustable sealing part 5 unseals the opening 4 at the corresponding end of the corresponding tubular reactor body 1, and the plurality of tubular reactor bodies 1 are sequentially communicated to provide a reaction site for the reaction liquid; when it is necessary to disassemble one of the tubular reactor bodies 1, first adjust the adjustable sealing parts 5 at both ends of the tubular reactor body 1 to be disassembled and the adjustable sealing parts 5 at the ends of the tubular reactor bodies 1 connected to the tubular reactor body 1 to be disassembled, so that the adjustable sealing parts 5 seal the openings 4 at the corresponding ends of the corresponding tubular reactor bodies 1, and then the tubular reactor body 1 to be disassembled can be disassembled, avoiding the outflow of the reaction liquid in the tubular reactor body 1 to be disassembled and other tubular reactor bodies 1, reducing the waste of the reaction liquid, and ensuring the cleanliness of the working environment.

[0017] In this embodiment, the arrangement and installation positioning methods of the plurality of tubular reactor bodies 1 can refer to the corresponding structures in CN220478839U in the background art.

[0018] Among them, the installation part 3 and the corresponding connection ear 2 are integrally formed, so it has sufficient structural strength.

[0019] To better understand this solution, the following will further optimize structures such as the adjustable sealing part 5.

[0020] As Figure 2 and Figure 3 shown, according to another embodiment of the utility model, in the tubular reactor, an installation cavity 6 extending into the corresponding connection ear 2 and communicating with the corresponding opening 4 is formed in the installation part 3. The adjustable sealing part 5 includes a sealing block 51 and an adjustment structure. The sealing block 51 is slidably arranged in the installation cavity 6; the adjustment structure is connected to the sealing block 51 and is used to adjust the sliding of the sealing block 51 to seal or unseal the opening 4.

[0021] When in use, the sealing block 51 is moved in the installation cavity 6 through the adjustment structure, so as to seal or unseal the corresponding opening 4 by the sealing block 51, which can meet the connection requirements of the plurality of tubular reactor bodies 1 during use and the requirement of sealing the corresponding opening 4 when disassembling any one of the tubular reactor bodies 1.

[0022] Based on the above solution:

[0023] The adjusting structure includes an adjusting screw rod 52 and a guiding rod 53. One end of the adjusting screw rod 52 is threadedly connected to the sealing block 51, and the other end extends outside the installation part 3 along the sliding direction of the sealing block 51. There is at least one guiding rod 53, and they are all arranged in the installation cavity 6 along the sliding direction of the sealing block 51. The guiding rods 53 are also slidably connected to the sealing block 51.

[0024] During adjustment, hold the end of the adjusting screw rod 52 extending outside the installation part 3 to rotate the adjusting screw rod 52. With the guiding function of the guiding rod 53, drive the sealing block 51 to slide in the installation cavity 6. When the sealing block 51 slides to the corresponding opening 4 to block it, seal the opening 4 (such as Figure 2 ); when the sealing block 51 slides to one side of the corresponding opening 4 to disengage from blocking it, unseal the opening 4 (such as Figure 3 ).

[0025] In order to enable the sealing block 51 to slide stably, ensure the adjusting structure is more concise and has a lower cost, there are two guiding rods 53, which are distributed on different sides of the adjusting screw rod 52.

[0026] Such as Figure 1 and Figure 4 shown, according to another embodiment of the present invention, in the tubular reactor, a turbulator mixing assembly is provided in each tubular reactor body 1.

[0027] The turbulator mixing assembly is used to increase the mixing effect of the reaction liquid flowing into the tubular reactor body 1, thereby improving the product yield, etc.

[0028] Wherein, the turbulator mixing assembly includes a plurality of turbulator mixing parts 7 spaced along the axial direction of the tubular reactor body 1. Through the cooperation of the plurality of turbulator mixing parts 7 in the tubular reactor body 1, the flow mode of the reaction liquid is intermittently changed to improve the mixing effect of the reaction liquid. In this embodiment, the number of turbulator mixing parts 7 is shown as three.

[0029] Based on the above solution:

[0030] Each turbulator mixing part 7 includes a spiral turbulator groove 71 and a liquid distribution structure 72. The spiral turbulator groove 71 is arranged on the inner wall of the tubular reactor body 1 and is distributed along its axial direction; the liquid distribution structure 72 is arranged in the tubular reactor body 1 and is located behind the spiral turbulator groove 71 and is spaced apart.

[0031] The reaction liquid flowing into the tubular reactor body 1 is accelerated in the tubular reactor body 1 through the spiral flow disturbing groove 71, and the reaction liquid impacts on the liquid distribution structure 72 and is evenly distributed for flowing; the reaction liquid adopts the above method multiple times in the tubular reactor body 1 to fully mix the reaction liquid.

[0032] In this embodiment:

[0033] Specifically, the liquid distribution structure 72 includes a liquid distribution block 721 adapted to the tubular reactor body 1. A number of liquid distribution holes 722 arranged in parallel are evenly distributed on the liquid distribution block 721, and each liquid distribution hole 722 is distributed along the axial direction of the tubular reactor body 1.

[0034] The reaction liquid flowing into the tubular reactor body 1 is accelerated in the tubular reactor body 1 through the spiral flow disturbing groove 71. After the reaction liquid impacts on one end of the liquid distribution block 721, it is evenly distributed through a number of liquid distribution holes 722 for flowing; the reaction liquid adopts the above method multiple times in the tubular reactor body 1 to fully mix the reaction liquid. Among them, the liquid distribution block 721 is cylindrical, and the shape of the liquid distribution block 721 can be adjusted according to the shape change of the tubular reactor body 1.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
