Description

Technical Field

[0001] This utility model relates to the field of adsorption equipment, specifically to an adsorption equipment for pretreatment of C5 raw materials. Background Technology

[0002] C5 feedstocks typically contain sulfides, moisture, and impurities, which can affect subsequent processing steps such as hydrogenation and polymerization. Adsorption pretreatment can effectively remove these impurities, improving the purity and quality of the feedstock.

[0003] The adsorption process typically takes place in a fixed-bed reactor, which is filled with solid particles (adsorbent). Fluid enters through the reactor inlet and is evenly distributed throughout the beds, contacting the adsorbent in the fixed bed. Under the action of the adsorbent, impurities in the fluid are adsorbed. During the adsorption process, even if the adsorbent has not reached its saturation adsorption capacity after a certain period of use, it may need to be replaced due to performance degradation.

[0004] Existing fixed-bed reactors mostly employ a drawer-type structure, requiring the bed to be pulled out to one side for adsorbent replacement. However, the bed needs to be in close contact with the reactor during installation to maintain a seal. Therefore, those skilled in the art have provided a C5 feedstock pretreatment adsorption device to solve the problems mentioned in the background art. Utility Model Content

[0005] To solve the above technical problems, this utility model provides a C5 raw material pretreatment adsorption device, including a support frame, a reaction vessel fixedly connected above the support frame, a replacement port on one side of the reaction vessel, and multiple adsorbent beds inserted inside the replacement port, the adsorbent beds being arranged sequentially from top to bottom;

[0006] The adsorbent bed has a slot at one end inside the replacement port. A lead screw is rotatably connected inside the slot, and a movable plate is threaded to the outside of the lead screw. A movable plate is slidably connected to the movable plate. The upper end of the adsorbent bed has an opening, and the upper end of the movable plate is located inside the opening. Connecting columns are fixedly connected to both sides of the movable plate. A support rod is fixedly connected inside the slot below the connecting columns, with one end of the support rod tilted upward. Limiting plates are fixedly connected inside the replacement port above the adsorbent bed, with the lower end of the limiting plate flush with the upper end of the adsorbent bed.

[0007] Preferably, the reactor has an inlet at the top and an outlet at the bottom, with the outlet located in the middle of the support frame and an opening on one side of the support frame.

[0008] Preferably, the other end of the adsorbent bed is inserted into the support frame, and an installation groove is provided at the other end of the adsorbent bed, with mesh holes below the installation groove.

[0009] Preferably, one end of the lead screw is slidably connected to a rotating handle, which can be moved to the outside of the slot.

[0010] Preferably, when the height of the connecting column is at its lowest, its upper end is flush with the uppermost end of the adsorbent bed.

[0011] Preferably, the adsorbent bed is provided with a sealing ring on the contact surface with the replacement port.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model is designed with a movable plate and a retractable plate. When the retractable plate moves with the movable plate, it rises and can be locked on one side of the limiting plate, thus locking the adsorbent bed on one side of the reactor and preventing it from falling off.

[0014] 2. This utility model is designed with a movable plate and a removable plate. When the removable plate moves and comes into contact with the limiting plate, the removable plate cannot move. The screw rotates and pushes the adsorbent bed into the reactor, thereby pressing the reactor tightly against one side of the reactor and ensuring the sealing between the adsorbent bed and the reactor.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figures 1-4 In this embodiment, a C5 raw material pretreatment adsorption device is provided, including a support frame 1, a reaction vessel 2 is fixedly connected above the support frame 1, a replacement port 5 is opened on one side of the reaction vessel 2, and multiple adsorbent beds 6 are inserted inside the replacement port 5, and the adsorbent beds 6 are arranged sequentially from top to bottom.

[0027] One end of the adsorbent bed 6 is located inside the replacement port 5 and has a slot 62. A lead screw 63 is rotatably connected inside the slot 62. A movable plate 65 is threadedly connected to the outside of the lead screw 63. A movable plate 66 is slidably connected up and down inside the movable plate 65. The upper end of the adsorbent bed 6 has an opening. The upper end of the movable plate 66 is located inside the opening. Connecting columns 67 are fixedly connected to both sides of the movable plate 66. A support rod 68 is fixedly connected below the connecting column 67 inside the slot 62. One end of the support rod 68 is inclined upward. Limiting plates 51 are fixedly connected inside the replacement port 5 above the adsorbent bed 6. The lower end of the limiting plate 51 is flush with the upper end of the adsorbent bed 6.

[0028] When replacing, rotate the lead screw 63, and the moving plate 65 moves to the innermost side of the slot 62. The movable plate 66 moves together with the moving plate 65, and the connecting column 67 descends along the support rod 68. When the user pulls out the adsorbent bed 6, the connecting column 67 will not come into contact with the limiting plate 51 and be blocked.

[0029] When reinserting after replacement, rotate screw 63. Movable plate 66 moves away from the inside of groove 62 along with moving plate 65. Movable plate 66 rises along support rod 68 via connecting column 67 and contacts limiting plate 51. Adsorbent bed 6 cannot be pulled out from replacement port 5. At the same time, continue to rotate screw 63. If moving plate 65 cannot move, screw 63 moves with installation groove 61 towards the inside of reactor 2, so that adsorbent bed 6 is pressed tightly against replacement port 5 to enhance its sealing.

[0030] In this embodiment, specifically, a liquid inlet 3 is provided above the reactor 2, and a liquid outlet 4 is provided below the reactor 2. The liquid outlet 4 is located in the middle of the support frame 1, and an opening is provided on one side of the support frame 1. Fluid flows in from the liquid inlet 3, and the fluid is adsorbed after passing through the multi-layer adsorbent bed 6. After adsorption, it is discharged through the liquid outlet 4, and the opening is used to connect to the pipeline.

[0031] In this embodiment, specifically, the other end of the adsorbent bed 6 is inserted into the support frame 1, and an installation groove 61 is provided at the other end of the adsorbent bed 6. A mesh is provided below the installation groove 61. The adsorbent is placed inside the installation groove 61 for adsorption.

[0032] In this embodiment, specifically, a rotating handle 64 is slidably connected to one end of the lead screw 63, and the rotating handle 64 can be moved to the outside of the slot 62. When the rotating handle 64 is pulled outward to move out of the slot 62, it can be rotated without being obstructed by the slot 62.

[0033] In this embodiment, specifically, when the connecting column 67 is at its lowest height, its upper end is flush with the uppermost end of the adsorbent bed 6. This allows the connecting column 67 to slide out from under the limiting plate 51 together with the adsorbent bed 6.

[0034] In this embodiment, specifically, a sealing ring 52 is provided at the contact surface between the adsorbent bed 6 and the replacement port 5. The sealing ring 52 increases the sealing performance between the adsorbent bed 6 and the replacement port 5.

[0035] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
