Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite tower technology, and in particular to a multi-layer composite tower for multiphase separation. Background Technology
[0002] As petrochemical feedstocks become increasingly heavier, traditional separation equipment can no longer meet the current high-standard separation requirements. In modern refining processes, the efficiency of removing micron-sized bubbles and fine particles from feedstocks directly affects product quality and energy consumption. The industry urgently needs to develop new, high-efficiency separation equipment to address this challenge. Especially in key process stages such as catalytic cracking and residue hydrotreating, improving multiphase separation efficiency is crucial for reducing production costs and increasing product yield.
[0003] Currently, the separation towers commonly used in industry mainly rely on single-point feeding and simple flow guiding structures to achieve gas-liquid separation. Their internal components are mostly fixed by welding. These devices are usually equipped with a single layer of packing or sieve plate as the main separation element, and complete the basic separation process through independent gas-liquid phase channels. Although some improved models have added simple distribution devices such as flow guide cones, the overall flow field control capability is still limited.
[0004] Existing separation towers suffer from severe uneven liquid phase distribution, resulting in low separation efficiency. Due to the lack of an effective diversion mechanism, most of the liquid phase load is concentrated in the central region of the tower, causing premature flooding in the center and dry areas at the edges. This uneven distribution leads to excessively high fluctuations in the fine particle removal rate, making it difficult to meet the stringent requirements of modern processes for separation precision. Therefore, a multi-layer composite tower for multiphase separation is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a multi-layer composite tower for multiphase separation, which aims to improve the low separation efficiency caused by severely uneven liquid phase distribution and the phenomenon that most of the liquid phase load is concentrated in the central area of the tower due to the lack of an effective diversion mechanism, resulting in premature flooding in the center and dry areas at the edges.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite tower for multiphase separation, comprising a first separation tower, a discharge port fixedly connected to the outer wall of the first separation tower, a sieve plate first disposed inside the first separation tower, a second separation tower fixedly connected to the upper surface of the first separation tower, a packing plate disposed inside the second separation tower, a third separation tower fixedly connected to the upper surface of the second separation tower, an inlet and an exhaust port fixedly connected to the outer wall of the third separation tower, a cyclone separator fixedly connected to the outer wall of the inlet and exhaust port, a second sieve plate second disposed inside the third separation tower, and a flow divider assembly disposed on the inner wall of the second separation tower;
[0007] The diversion assembly includes a diversion plate, a diversion plate, and a guide plate. The outer wall of the diversion plate is fixedly connected to the inner wall of the second separation tower, the outer wall of the diversion plate is fixedly connected to the inner wall of the second separation tower, and the upper surface of the guide plate is fixedly connected to the lower surface of the diversion plate.
[0008] Furthermore, the inner wall of the separation tower is fixedly connected to the connecting block two, and the outer wall of the sieve plate two is slidably connected to the inner wall of the connecting block two.
[0009] Furthermore, a connecting block three is fixedly connected to the outer wall of the second sieve plate, and a connecting block one is fixedly connected to the outer wall of the third connecting block.
[0010] Furthermore, the outer wall of the connecting block is fixedly connected to the inner wall of the separation tower, and a sealing block is fixedly connected to the outer wall of the connecting block.
[0011] Furthermore, the second sieve plate is slidably connected to the outer wall of the third connecting block on the inner wall of the sealing block, and the outer wall of the third separation tower is fixedly connected to the first fixing seat.
[0012] Furthermore, a fixing seat two is fixedly connected to the outer wall of the separation tower three, and bolts are threadedly connected to the inner wall of the fixing seat one.
[0013] Furthermore, the outer wall of the bolt is rotatably connected to the inner walls of connecting block one and connecting block three, and the outer wall of the bolt is rotatably connected to the inner wall of fixing seat two.
[0014] Furthermore, the cyclone separator is located inside the third separation tower and is positioned above the second sieve plate.
[0015] This utility model has the following beneficial effects:
[0016] In this invention, a three-stage synergistic flow separation mechanism is formed through the initial flow separation of the flow distribution plate, the dispersion of the flow distribution plate through the holes, and the lateral guidance of the flow guide plate. This ensures that the liquid phase is evenly distributed in the second and first separation towers, avoids load concentration in the central area, and ensures that the separation components such as the packing plate and the first sieve plate play their full role. At the same time, the consistent flow separation structure of the second and first separation towers achieves stepped deep processing, significantly improving the removal effect of microbubbles and fine particles. Finally, the first sieve plate achieves precise gas-liquid stratification, greatly improving the purity of the separated products.
[0017] In this invention, the second sieve plate is fixed with bolts and slidably engaged with the second connecting block. It can be quickly removed by pulling the third connecting block with a crane. The packing plate and the first sieve plate also adopt a sliding design, so cleaning or replacement can be completed without disassembling the tower body. This structure reduces the complexity of maintenance operations, shortens the time of a single maintenance, and avoids the impact of frequent disassembly and assembly on the sealing performance of the tower body. Combined with the anti-leakage function of the sealing block, it not only ensures the long-term stable operation of the equipment, but also reduces the maintenance manpower and time costs.

[0026] 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.
[0027] Reference Figures 1-4This utility model provides an embodiment of a multi-layer composite tower for multiphase separation, comprising a separation tower 1, with a discharge port 2 fixedly connected to the outer wall of the separation tower 1. The discharge port 2 is used to discharge the gaseous or liquid phase products that meet the purity requirements after deep processing by the separation tower 1, serving as the output channel for the qualified products after separation and ensuring the smooth collection of separation results. A sieve plate 14 is installed inside the separation tower 1 to achieve final gas-liquid stratification. Its sieve structure allows the liquid phase to pass through while blocking the gas phase, ensuring that the purity of the separated gas and liquid phases meets the requirements. A second separation tower 3 is fixedly connected to the upper surface of the separation tower 1, and packing material is installed inside the second separation tower 3. The packing structure on the surface of the packing plate 13 can further separate the tiny bubbles and fine particles entrained in the liquid phase. By increasing the contact area between the liquid phase and the packing, the separation effect is improved by adsorption and interception. The upper surface of the separation tower 2 3 is fixedly connected to the separation tower 3 4. The outer wall of the separation tower 3 4 is fixedly connected to the feed port 5 and the exhaust port 6. The exhaust port 6 is used to discharge the gas phase with a smaller density that has accumulated in the center after being separated by the cyclone separator 15, so as to achieve the initial separation of the gas phase and the liquid-solid phase. The outer wall of the feed port 5 and the exhaust port 6 is fixedly connected to the cyclone separator 15. The separation tower 3 4 is equipped with a sieve plate 2 17. The inner wall of the separation tower 2 3 is equipped with a flow divider.
[0028] The flow distribution assembly includes a flow distribution plate 10, a flow distribution plate 11, and a flow guide plate 12. The outer wall of the flow distribution plate 10 is fixedly connected to the inner wall of the second separation tower 3. The flow distribution plate 10 performs preliminary flow distribution on the liquid phase entering the second separation tower 3, dispersing the liquid phase into multiple streams. The outer wall of the flow distribution plate 11 is fixedly connected to the inner wall of the second separation tower 3. The flow distribution plate 11 further disperses the liquid phase evenly through multiple holes on the plate, increasing the contact area between the liquid phase and subsequent separation components and improving the separation efficiency. The upper surface of the flow guide plate 12 is fixedly connected to the lower surface of the flow distribution plate 11. The flow guide plate 12 guides the liquid phase dispersed by the flow distribution plate 11 to both sides of the second separation tower 3 and the first separation tower 1, avoiding the liquid phase from concentrating in the central area and causing excessive load, ensuring that the force on each area of the separation components is uniform and that they play their full role. The inner wall of the third separation tower 4 is fixedly connected to a connecting block 2 16, and the outer wall of the sieve plate 2 17 is slidably connected to the inner wall of the connecting block 2 16.
[0029] Reference Figures 1-6A connecting block 20 is fixedly connected to the outer wall of sieve plate 217. Sieve plate 217 receives the liquid and solid phases sinking from hydrocyclone separator 15. Through its sieve hole structure, it quickly separates the larger solid particles in the mixture, realizing liquid-solid phase separation. A connecting block 8 is fixedly connected to the outer wall of connecting block 320. The outer wall of connecting block 8 is fixedly connected to the inner wall of separation tower 34. A sealing block 19 is fixedly connected to the outer wall of connecting block 8. Sieve plate 217 and the outer wall of connecting block 320 are slidably connected to the inner wall of sealing block 19. Sealing block 19 is installed in the connection gap of each component. The gaps effectively prevent liquid phase leakage, ensuring the sealing of the separation process and avoiding material loss and corrosion of other parts of the equipment. The outer wall of the separation tower 3 4 is fixedly connected to the fixing seat 1 7 and the outer wall of the separation tower 3 4 is fixedly connected to the fixing seat 2 9. The inner wall of the fixing seat 1 7 is threaded with bolts 18. The outer wall of bolts 18 is rotatably connected to the inner wall of connecting block 1 8 and connecting block 3 20. The outer wall of bolts 18 is rotatably connected to the inner wall of fixing seat 2 9. The cyclone separator 15 is set inside the separation tower 3 4 and is set above the sieve plate 2 17.
[0030] Working Principle: When using a multi-layer composite tower for multiphase separation of a mixture, the mixture is conveyed from the feed inlet 5 into the hydrocyclone separator 15. After entering the hydrocyclone separator 15, the mixture forms a high-speed rotating flow field along the guide vanes. Under the action of centrifugal force, the denser liquid or solid phase is thrown towards the wall and sinks along the wall surface, while the less dense gas phase gathers in the center to form a cyclone nucleus, and is finally discharged from the exhaust port 6. The sinking liquid and solid phases fall onto the second sieve plate 17, where the larger solid particles in the mixture are quickly separated. The separated liquid phase enters the second separation tower 3, first undergoes preliminary separation by the diversion plate 10, and then flows to the diversion plate 11, where it is uniformly dispersed through multiple holes. Subsequently, it is guided to both sides by the guide plate 12 to avoid... The central area suffers from concentrated load, affecting separation efficiency. The liquid phase then flows through packing plate 13, further separating the entrained microbubbles and fine particles. The flow distribution structure within separation tower 1 is identical to that of separation tower 2. After deep processing within separation tower 1, the liquid phase undergoes final gas-liquid stratification via sieve plate 14, ensuring the purity of both the gas and liquid phases. Qualified products are discharged from outlet 2. For maintenance, cleaning and replacement of sieve plate 2 17 can be accomplished by unscrewing bolts 18 and having a crane pull connecting block 3 20, causing sieve plate 2 17 to slide out from connecting block 2 16. Packing plate 13 and sieve plate 1 14 also feature a sliding design for easy cleaning and maintenance. Sealing block 19 effectively prevents liquid phase leakage from the joints between components, ensuring the sealing of the separation process.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
