Description

Technical Field

[0001] This utility model relates to the field of alkylation reaction vessel technology, and in particular to a novel multi-channel alkylation reactor. Background Technology

[0002] The novel multi-channel alkylation reactor is a device specifically designed for alkylation reactions, commonly used in petrochemical, fine chemical, and other fields. Alkylation is an important catalytic reaction, primarily used to react olefins such as ethylene and propylene with alkanes such as isobutane in the presence of a catalyst to produce high-octane alkylates such as isooctane. These products are widely used in gasoline blending to improve fuel performance.

[0003] To avoid downtime for maintenance in case of reactant feed pipe damage, existing multi-channel alkylation reactors typically have two feed pipes on the reactor. This allows for the immediate opening of the alternative feed pipe if one of the feed pipes fails. However, the reactor still needs to be shut down for maintenance when the damaged feed pipe is replaced.

[0004] Therefore, a novel multi-channel alkylation reactor is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a novel multi-channel alkylation reactor to solve the above-mentioned problems, thereby improving the problem of needing to shut down the reaction vessel for maintenance when replacing a damaged feed pipe.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a novel multi-channel alkylation reactor, comprising: a reaction vessel, the lower end of which is connected to a conduit; two feed pipes at the top of the conduit; valves embedded in the surface of the feed pipes; and an installation mechanism, comprising a sealing ring fixedly connected to the bottom end of the feed pipes, the surface of which is engaged with the upper end of the conduit surface; several fixing brackets fixedly connected to the upper end of the conduit surface; pressure blocks slidably connected to the inner walls of the fixing brackets; and a first spring fixedly connected to the opposite ends of the fixing brackets and pressure blocks. The elastic force of the first spring pushes the pressure blocks to move, thereby moving them away from the top of the sealing ring, thus releasing the fixed state of the feed pipes and the conduit, allowing for replacement of damaged feed pipes without stopping the reactor.

[0007] Preferably, a plurality of mounting brackets are fixedly connected to the upper surface of the conduit, and a connecting frame is slidably connected to the surface of the mounting bracket. A ring-shaped limiting block is fixedly connected to the top of the connecting frame, and a second spring is fixedly connected to the opposite end of the mounting bracket and the connecting frame. The elastic force of the second spring pushes the connecting frame and the limiting block upward, thereby causing the pressure block to move and abut against the top of the sealing ring, thus enabling the feed pipe to be quickly installed on the conduit.

[0008] Preferably, a sliding rod is slidably connected to the inner wall of the connecting frame, and the surface of the sliding rod is sequentially slidably connected to the inner walls of one of the mounting brackets and one of the fixing brackets. The sliding rod locks the connecting frame, preventing it from shifting downwards and ensuring the feed pipe is stably installed on the guide tube.

[0009] Preferably, a slider is fixedly connected to the surface of the slide rod.

[0010] Preferably, the inner wall of the connecting frame is provided with a groove, and the surface of the slider is slidably connected to the inner wall of the groove. Through the slider and the groove, the range of lateral movement of the slide rod is limited, ensuring the stability of the slide rod within the connecting frame, thereby allowing the limiting block to stably abut against the surface of the pressure block.

[0011] Preferably, the limiting block is in the shape of a right triangle, and the surface of the pressing block contacts the inclined surface of the limiting block.

[0012] Preferably, a pulley is rotatably connected to the upper surface of the fixing frame. The pulley enables the sealing ring to be locked onto the conduit for precise engagement, ensuring that the sealing ring is accurately engaged within the conduit.

[0013] The beneficial effects of this utility model are:

[0014] The pressure block is moved by the elastic force of the first spring, which moves the pressure block away from the top of the sealing ring, thereby releasing the fixed state of the feed pipe and the conduit. Compared with the existing method that requires shutting down the operation of the reaction tank to replace the damaged feed pipe, this method can replace the damaged feed pipe without stopping the machine.

[0015] The elastic force of the second spring pushes the connecting frame and the limiting block upward, thereby causing the pressure block to move and abut against the top of the sealing ring, so that the feed pipe can be quickly installed on the guide tube. The sliding rod locks the connecting frame to prevent it from moving downward, thus ensuring that the feed pipe is stably installed on the guide tube. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-5 As shown, a novel multi-channel alkylation reactor includes: a reaction vessel 1, with a conduit 2 connected to the lower end of the surface of the reaction vessel 1, and two feed pipes 3 at the top of the conduit 2, with valves 4 embedded in the surface of the feed pipes 3; an installation mechanism 5, including a sealing ring 51 fixedly connected to the bottom end of the feed pipes 3, the surface of the sealing ring 51 being snapped onto the upper end of the surface of the conduit 2, a plurality of fixing brackets 52 fixedly connected to the upper end of the surface of the conduit 2, a pressure block 53 slidably connected to the inner wall of the fixing bracket 52, a first spring 54 fixedly connected to the opposite end of the fixing bracket 52 and the pressure block 53, and a limiting block 57 being in the shape of a right triangle, with the surface of the pressure block 53 contacting the inclined surface of the limiting block 57.

[0024] The top of the reaction vessel 1 is connected to the reactant outlet pipe, the surface of the reaction vessel 1 is covered with an insulation sleeve, the upper surface of the insulation sleeve is connected to the water inlet pipe, the lower surface of the insulation sleeve is connected to the water outlet pipe, the upper surface of the reaction vessel 1 is provided with a transparent observation window, and the interior of the reaction vessel 1 is provided with several channels.

[0025] The multiple channels inside reaction vessel 1 can work independently or in concert to adapt to different reaction conditions and requirements.

[0026] The working principle of the novel multi-channel alkylation reactor is based on the alkylation reaction, where low-carbon alkanes such as propane and butane undergo an addition reaction with olefins such as butene and pentene under the action of a catalyst to produce high-carbon alkylated products such as octane and hexadecane. In reaction vessel 1, olefins and alkylating agents enter the interior of reaction vessel 1 through multiple channels, are adsorbed on the surface of the catalyst, and undergo molecular cracking to form carbon intermediates. These intermediates then undergo an alkylation reaction under the action of a catalyst to generate alkyl compounds. During the reaction, parameters such as temperature and pressure within reaction vessel 1 are precisely controlled to ensure efficient reaction and product quality. The workflow of producing high-octane gasoline blending components and lubricating oils using a multi-channel alkylation reactor is a relatively mature and conventional technology, and will not be elaborated upon here.

[0027] When one of the feed pipes 3 is damaged, open the valve 4 on the feed pipe 3 to open the inside of the feed pipe 3 to make the inside of the feed pipe 3 open, and close the valve 4 on the other feed pipe 3 to close the inside of the other feed pipe 3, so that the material enters the channel inside the reaction tank 1 through the feed pipe 3 and the conduit 2.

[0028] like Figure 3-5 As shown, several mounting brackets 55 are fixedly connected to the upper surface of the conduit 2. A connecting frame 56 is slidably connected to the surface of the mounting bracket 55. A ring-shaped limiting block 57 is fixedly connected to the top of the connecting frame 56. A second spring 58 is fixedly connected to the opposite end of the mounting bracket 55 and the connecting frame 56. A slide rod 59 is slidably connected to the inner wall of the connecting frame 56. The surface of the slide rod 59 is slidably connected to the inner wall of one of the mounting brackets 55 and one of the fixed brackets 52 in sequence. A slider 511 is fixedly connected to the surface of the slide rod 59. A groove 510 is opened in the inner wall of the connecting frame 56. The surface of the slider 511 is slidably connected to the inner wall of the groove 510. A pulley 512 is rotatably connected to the upper surface of the fixed bracket 52.

[0029] Align the new feed tube 3 above the guide tube 2, so that the sealing ring 51 on the new feed tube 3 contacts the surface of the pulley 512. The pulley 512 limits the placement of the sealing ring 51, so that the sealing ring 51 is precisely engaged in the guide tube 2. Loosen the connecting frame 56. The elastic force of the second spring 58 pushes the connecting frame 56 upward. The upward movement of the connecting frame 56 drives multiple limiting blocks 57 upward, so that the inclined surface of the limiting block 57 contacts the surface of the pressure block 53 and pushes the pressure block 53 to move. So that the bottom of the pressure block 53 abuts the top of the sealing ring 51. Push the slide rod 59, so that the slide rod 59 slides into one of the mounting brackets 55, the connecting frame 56 and one of the fixing brackets 52 in sequence. Rotate the slide rod 59, so that the surface of the slider 511 moves in a ring on the inner wall of the slide groove 510, so that the slide rod 59 is stably located on the inner wall of one of the mounting brackets 55, thereby installing the new feed tube 3 on the guide tube 2.

[0030] In use, rotating the slide rod 59 causes the slider 511 to move in a ring, pulling the slide rod 59 and causing the slider 511 to disengage from the inner wall of the slide groove 510. This moves the slide rod 59 away from the inner walls of one of the fixing frames 52, the connecting frame 56, and one of the mounting frames 55. Pressing the connecting frame 56 causes the limiting block 57 to move down and squeeze the second spring 58. The side of the limiting block 57 gradually moves down, thereby releasing the pressure on the pressure block 53. At this time, the elastic force of the first spring 54 pushes the pressure block 53 toward the side of the limiting block 57, so that the bottom of the pressure block 53 is away from the top of the sealing ring 51, pulling the damaged feed pipe 3 and separating the feed pipe 3 from the guide pipe 2.

[0031] It should be noted that the reaction vessel 1, conduit 2, feed pipe 3, valve 4, first spring 54 and second spring 58 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the reaction vessel 1 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
