Description

Technical Field

[0001] This application relates to the technical field of dehydrogenation, and particularly to a dehydrogenation reactor. Background Technology

[0002] A dehydrogenation reactor is a device used to carry out dehydrogenation reactions, which are common reaction types in organic chemistry and are widely used in petrochemicals, fine chemical synthesis, and hydrogen production. Some dehydrogenation reactions generate byproducts, which are acidic substances that can react with metals.

[0003] After the reactants undergo a dehydrogenation reaction in the reaction bed, the generated product is discharged from the outlet. The generated product may contain acidic substances. The outlet is usually made of metal. These acidic substances will corrode the inner wall of the outlet as they pass through it. Since the outlet is an integral structure with the outer shell of the dehydrogenation reactor, it is impossible for the staff to disassemble and replace it. Utility Model Content

[0004] This application provides a dehydrogenation reactor to solve the problem in related technologies where the outlet cannot be replaced after corrosion.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] This application provides a dehydrogenation reactor that solves the problem in related technologies where the outlet cannot be replaced after corrosion.

[0032] Please see Figures 1 to 6 A dehydrogenation reactor includes: a shell 1, an outlet 2 on the shell 1, an outlet pipe 3, the outlet pipe 3 being disposed on the outlet 2, and a plurality of fixing structures 4 on the outlet pipe 3. The fixing structure 4 includes a sleeve 41, a fixing groove 42, and a fixing member 43. The sleeve 41 can be inserted into the outlet 2, the fixing groove 42 is disposed on the outlet 2, and the fixing member 43 is slidably connected to the sleeve 41. The moving direction of the fixing member 43 is perpendicular to the moving direction of the sleeve 41, and the fixing member 43 can be inserted into the fixing groove 42.

[0033] In this embodiment, there are four fixing structures 4. The four fixing structures 4 are arranged circumferentially around the outside of the air outlet pipe 3, so that the air outlet pipe 3 is more firmly fixed to the outer shell 1. When installing the air outlet pipe 3 on the outer shell 1, first align the air outlet pipe 3 with the outlet 2, then pass the sleeve 41 through the air outlet pipe 3 and insert it into the edge of the outlet 2, and then insert the fixing member 43 into the fixing groove 42, thereby fixing the air outlet pipe 3 to the outer shell 1 and realizing the detachability between the air outlet pipe 3 and the outer shell 1.

[0034] It should be noted that when the sleeve 41 is inserted into the edge of the outlet 2, the fastener 43 extends out of the sleeve 41 when it is inserted into the fixing groove 42. When the fastener 43 is pulled out of the fixing groove 42, the fastener 43 will retract into the sleeve 41.

[0035] Specifically, in this embodiment, the fixing structure 4 further includes a slide groove 44, a slider 45, a first spring 46, and a plug shaft 47. The slide groove 44 is formed on the sleeve 41. The slider 45 is connected to the fixing member 43 and is slidably connected in the slide groove 44. The two ends of the first spring 46 are respectively connected to the slider 45 and the sleeve 41. The plug shaft 47 is slidably connected in the sleeve 41. The moving direction of the plug shaft 47 is the same as the length direction of the sleeve 41. The plug shaft 47 can compress the fixing member 43.

[0036] The first spring 46 continuously provides a force to the fixing member 43 to retract into the sleeve 41. When the insert shaft 47 moves deeper into the sleeve 41, the insert shaft 47 will squeeze one side of the fixing member 43. The fixing member 43 is squeezed out of the sleeve 41 and inserted into the fixing groove 42 to fix the outer shell 1 and the air outlet pipe 3. When it is necessary to remove the air outlet pipe 3 from the outer shell 1, it is only necessary to pull the insert shaft 47 out of the sleeve 41. The fixing member 43 is subjected to the force of the first spring 46 and retracts into the sleeve 41. At this time, the operator can separate the air outlet pipe 3 from the outer shell 1 along the direction perpendicular to the length of the outer shell 1. Compared with directly controlling the fixing member 43 to realize the installation and removal of the air outlet pipe 3, this embodiment undoubtedly makes it more convenient for the operator to operate by controlling the position of the insert shaft 47.

[0037] In a preferred embodiment, the slider 45 slides in the groove 44, so that as the fixing member 43 extends out of or retracts from the sleeve 41, the fixing member 43 moves along the length direction of the groove 44. When there are two sliders 45 and two grooves 44, and the two sliders 45 are arranged opposite each other on both sides of the fixing member 43, the fixing member 43 will not tilt during the movement.

[0038] More specifically, in this embodiment, the fixing structure 4 also includes a mating block 48, a mating groove 49, and a second spring 410. The mating groove 49 is disposed on the insert shaft 47, and the mating block 48 is slidably connected to the sleeve 41. The mating block 48 can be inserted into the mating groove 49.

[0039] There is a slot in the sleeve 41 for the mating block 48 to slide, so that the sliding direction of the mating block 48 is perpendicular to the moving direction of the insert shaft 47. The slot guides the mating block 48. When the air outlet pipe 3 is fixed on the outer shell 1, the mating block 48 moves into the sleeve 41 and inserts into the mating groove 49, fixing the position of the insert shaft 47 in the sleeve 41 and preventing the insert shaft 47 from popping out of the sleeve 41, which would cause the air outlet pipe 3 to detach from the outer shell 1.

[0040] Furthermore, in this embodiment, the two ends of the second spring 410 are respectively connected to the mating block 48 and the sleeve 41;

[0041] The second spring 410 will continuously provide a force to the mating block 48 to move it into the sleeve 41. That is, when the mating block 48 is inserted into the mating groove 49, the second spring 410 will hold the mating block 48 in place to prevent the mating block 48 from coming out of the mating groove 49 due to gravity. Before the insertion shaft 47 is inserted into the sleeve 41, the mating block 48 needs to be moved outward from the sleeve 41 to prevent the mating block 48 from affecting the insertion of the insertion shaft 47 into the sleeve 41.

[0042] The working principle of this application is as follows:

[0043] During installation, the air outlet pipe 3 is first aligned with the outlet 2. Then, the sleeve 41 is passed through the air outlet pipe 3 and inserted into the edge of the outlet 2. Next, the mating block 48 is moved outward from the sleeve 41, and the insertion shaft 47 is inserted into the sleeve 41. At this time, the fixing member 43 is squeezed into the fixing groove 44. Under the action of the second spring 410, the mating block 48 is inserted into the mating groove 49, fixing the position of the insertion shaft 47. The above steps are repeated continuously to complete the installation of the four fixing structures 4 and fix the air outlet pipe 3 to the outer shell 1.
