Description

Technical Field

[0002] In natural gas dehydration and heavy hydrocarbon removal processes, the composite adsorption tower is a key piece of equipment, and the stability and safety of the connections between its tower sections directly affect the stable operation and safety of the entire treatment system. Traditional tower connection methods, such as bolted connections and welding, while meeting connection requirements to some extent, often suffer from problems such as complex connections, cumbersome operation, and susceptibility to loosening or damage, resulting in insufficient stability and safety of the connections between tower sections. These problems are particularly pronounced under harsh operating conditions, such as high temperature, high pressure, and corrosive gases, severely impacting the service life and treatment efficiency of the composite adsorption tower.

[0003] Furthermore, with the continuous development of natural gas processing technology and the increasing demands for applications, higher requirements are being placed on the ease of operation and maintenance efficiency of composite adsorption towers. Traditional tower connection methods often require complex on-site assembly and debugging, which is not only time-consuming and labor-intensive but also increases the difficulty and complexity of manual operation. At the same time, the diversity and complexity of connecting components also bring significant difficulties to subsequent maintenance and upkeep. These problems not only affect the operating efficiency of the composite adsorption tower but also increase the equipment's maintenance costs and time. Therefore, we provide a composite adsorption tower structure for natural gas dehydration and heavy hydrocarbon removal. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution for a composite adsorption tower structure for natural gas dehydration and heavy hydrocarbon removal: The structure mainly consists of tower body 1, tower body 2, and tower body 3, which are joined together to form a complete composite adsorption tower for natural gas dehydration and heavy hydrocarbon removal. To ensure a stable connection between the tower bodies, an anti-detachment mechanism is designed. The anti-detachment mechanism includes a sleeve 5 fitted onto the end of tower body 1. An annular plate 4 is fixed around the outer periphery of tower body 2 and tower body 3. An arc-shaped groove 6 is provided around the outer periphery of the annular plate 4. A limit insertion hole 7 is provided on the end wall of the arc-shaped groove 6. An arc-shaped groove 8 is provided on the opposite end face of the sleeve 5. An arc-shaped sleeve block 9 is slidably connected in the arc-shaped groove 8. The two arc-shaped sleeve blocks 9 are connected by a connecting rod 10. A fixing sleeve block 11 is fixed around the connecting rod 10. The fixing sleeve block 11 is then connected to a connecting plate 12. A limit insertion rod 13 is fixed on the connecting plate 12. In addition, a reciprocating structure is provided between the arc-shaped groove 8 and the arc-shaped sleeve block 9, so that the arc-shaped sleeve block 9 and the limit insertion rod 13 can move flexibly and be locked in an appropriate position.

[0026] like Figure 1-5 As shown, a stabilizing component is also provided between the sleeve 5 and the connecting plate 12. The stabilizing component includes an annular groove 16 around the sleeve 5, a guide slider 17 slidably connected in the annular groove 16, and a guide groove 18 on the inner side wall of the annular groove 16, a guide slider 2 slidably connected in the guide groove 18. The opposing surfaces of the two guide sliders 2 19 are fixedly connected to the two side surfaces of the guide slider 17, and the guide slider 17 is then fixedly connected to the connecting plate 12. The stabilizing component further enhances the connection strength between the sleeve 5 and the connecting plate 12, and improves the stability of the entire anti-detachment mechanism.

[0027] like Figure 1-5 As shown, a sealing component is also provided between the annular plate 4 and the sleeve 5. The sealing component includes a sealing slot 20 on the surface of the annular plate 4, and a sealing ring 21 fixed to the end of the sleeve 5, which is inserted into the sealing slot 20. The sealing component ensures the sealing between the tower bodies, prevents gas leakage, and improves the working efficiency of the composite adsorption tower.

[0028] like Figure 1-5 As shown, the reciprocating structure includes an arc-shaped rod 14 between the two end walls of the arc-shaped groove 8, a spring 15 is sleeved around the arc-shaped rod 14, and an arc-shaped sleeve 9 is slidably sleeved on the arc-shaped rod 14. One end of the spring 15 is fixed to the end wall of the arc-shaped groove 8, and the other end is fixed to one end surface of the arc-shaped sleeve 9. The reciprocating structure allows the arc-shaped sleeve 9 and the limiting rod 13 to automatically pop out and lock in the limiting hole 7 when needed, improving the convenience and safety of operation.

[0029] like Figure 1-5 As shown, one end of the limiting rod 13 is inserted into the limiting hole 7, and the inner diameter of the limiting hole 7 is matched with the outer diameter of the limiting rod 13. The tight fit between the limiting rod 13 and the limiting hole 7 ensures a stable connection between the tower bodies and prevents them from separating during use.

[0030] like Figure 1-5 As shown, one end of the spring 15 is fixed to the end wall of the arc-shaped groove 8, and the other end is fixed to the end surface of the arc-shaped sleeve 9. This design allows the arc-shaped sleeve 9 to automatically reset when subjected to external force, ensuring that the limiting plug 13 can be accurately inserted into the limiting plug hole 7. The reset function of the spring 15 improves the locking stability and reliability of the limiting plug 13.

[0031] like Figure 1-5 As shown, the opposite surfaces of the two guide sliders 19 are fixedly connected to the two side surfaces of the guide slider 17, and the guide slider 17 is then fixedly connected to the connecting plate 12. This design enables the stabilizing component to firmly connect the sleeve 5 and the connecting plate 12, thereby improving the stability of the entire anti-detachment mechanism.

[0032] The working principle of this utility model is as follows: Tower body 1, tower body 2, and tower body 3 are spliced ​​together to form a complete composite adsorption tower for the dehydration and heavy hydrocarbon removal of natural gas. An anti-detachment mechanism is provided between the tower bodies to ensure a stable connection. This anti-detachment mechanism mainly consists of a sleeve 5, an annular plate 4, an arc-shaped groove 6, a limiting insertion hole 7, an arc-shaped groove 8, an arc-shaped sleeve block 9, a connecting rod 10, a fixing sleeve block 11, a connecting plate 12, and a limiting insertion rod 13. When the tower bodies are spliced ​​in place, the sleeve 5 contacts the annular plate 4. At this time, the arc-shaped sleeve block 9 slides within the arc-shaped groove 8 and moves the connecting plate 12 and the limiting insertion rod 13 via the connecting rod 10 and the fixing sleeve block 11. Due to the elastic force of the spring 15, the arc-shaped sleeve block 9 slides outward along the arc-shaped rod 14 until the limiting insertion rod 13 is inserted into the limiting insertion hole 7, thus achieving a stable connection between the tower bodies.

[0033] The stabilizing assembly consists of components such as annular groove 16, guide slider 17, guide groove 18, and guide slider 2 19, which are used to further enhance the connection strength between the sleeve 5 and the connecting plate 12. When the limiting rod 13 is inserted into the limiting hole 7, the guide slider 17 slides along the annular groove 16, while the guide slider 2 19 slides in the guide groove 18, forming an additional stabilizing connection.

[0034] The sealing component consists of components such as the sealing slot 20 and the sealing ring 21, which are used to ensure the sealing between the tower bodies. When the sleeve 5 contacts the annular plate 4, the sealing ring 21 will be inserted into the sealing slot 20 to form a tight sealing connection. Due to the design of the anti-detachment mechanism, the splicing and disassembly of the tower bodies become simple and quick.

[0035] Simply align the sleeve 5 with the annular plate 4, and the arc-shaped sleeve 9 will automatically slide and lock under the elastic force of the spring 15, thus completing the splicing. Similarly, during disassembly, only a slight external force needs to be applied to make the arc-shaped sleeve 9 slide, and the limiting rod 13 can be pulled out from the limiting hole 7, achieving quick disassembly.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
