A high and large thin-wall stripping tower mounting base

Abstract

This invention discloses a tall, thin-walled stripping tower mounting base, comprising a base and a mechanism box. A hollow ring is fixedly connected to the outer wall of the base, and multiple supports are fixedly connected to the side walls of the hollow ring. Cooling pipes are arranged inside the hollow ring in a serpentine pattern. A top rod is slidably connected inside the mechanism box, which also contains a rubber liquid bladder and inlet and outlet pipes communicating with the rubber liquid bladder. This invention utilizes a lifting device to move a floating plate up and down inside the stripping tower. On one hand, this accelerates the mixing of the liquid inside the stripping tower, improving the heating efficiency of the liquid. On the other hand, the elasticity of the rubber liquid bladder continuously delivers cooling water to the cooling pipes, thus cooling the base outside the stripping tower and preventing excessive thermal expansion and deformation of the base, which could damage the internal walls of the stripping tower.

Description

Technical Field

[0001] This invention relates to the field of stripping tower technology, and in particular to a tall, thin-walled stripping tower mounting base. Background Technology

[0002] Stripping is a unit operation used to recover absorbed solutes and separate the absorbent from the solute for regeneration. In some cases, stripping is also used to remove light components from liquids, such as in the oil refining industry where steam is often used as a stripping agent to remove light components from oil products. Therefore, stripping can be used in conjunction with absorption or alone.

[0003] Since stripping towers typically separate solvents with different boiling points through heating and evaporation, they are often located at high temperatures during long-term production. For tall, thin-walled stripping towers, the mounting bases are often situated within a dense cluster of towers with poor ventilation and inefficient heat dissipation. This leads to heat buildup and temperature rise on the mounting bases, which can cause thermal expansion and pressure on the tower walls, potentially resulting in wall dents and deformation, and in severe cases, even tower wall rupture and leakage. Therefore, this application proposes a mounting base for tall, thin-walled stripping towers. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tall, thin-walled stripping tower mounting base.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tall, thin-walled stripping tower mounting base includes a base and a mechanism box. A hollow ring is fixedly connected to the outer wall of the base, and multiple supports are fixedly connected to the side wall of the hollow ring. Cooling pipes are provided inside the hollow ring, and the cooling pipes are distributed in a serpentine pattern around the hollow ring. A top rod is slidably connected inside the mechanism box. A rubber liquid bladder is provided inside the mechanism box. An inlet pipe and an outlet pipe communicating with the rubber liquid bladder are also provided inside the mechanism box. A one-way inlet valve and a one-way outlet valve are respectively installed in the inlet pipe and the outlet pipe. The outlet pipe communicates with the cooling pipe. A sealing sleeve is provided outside the top rod, and the top rod slides up and down along the sealing sleeve. The outer wall of the top rod is tightly fitted with the inner wall of the sealing sleeve. A lifting device for raising and lowering the top rod is installed outside the sealing sleeve. A first float plate is fixedly connected to the upper end of the top rod, and the first float plate is fixedly connected to the upper end of the sealing sleeve by a first spring.

[0007] Preferably, the lifting device includes a plurality of suction cylinders fixedly connected to the side wall of the sealing sleeve. The suction cylinders are connected to a storage cylinder through a liquid inlet mechanism. The storage cylinders are connected to a lifting cylinder through a pressure pipe. A second float is slidably connected inside the lifting cylinder. A push rod is fixedly connected to the upper end of the second float. A pressure valve is installed inside the pressure pipe.

[0008] Preferably, the liquid inlet mechanism includes a liquid suction pipe, a liquid discharge pipe, and a piston. Both the liquid suction pipe and the liquid discharge pipe are connected to the liquid suction cylinder. A one-way shut-off valve is installed inside the liquid suction pipe and the liquid discharge pipe. The piston is slidably and sealed inside the liquid suction cylinder. The piston is driven to move by a drive mechanism.

[0009] Preferably, the driving mechanism includes a driving rod fixedly connected to the lower end of the piston, a pneumatic plate fixedly connected to the lower end of the driving rod, and the piston is connected to the inner bottom of the suction cylinder by a second spring.

[0010] Preferably, a third spring is fixedly connected to the lower end of the second float plate, and the end of the third spring away from the second float plate is fixedly connected to the bottom of the lifting cylinder.

[0011] Preferably, the inner wall of the lifting cylinder is provided with a drain hole, and the diameter of the drain hole is smaller than the diameter of the pressure pipe.

[0012] The present invention has the following beneficial effects:

[0013] 1. By setting a hollow ring and installing a ring-shaped distribution of cooling pipes inside the hollow ring, the floating plate inside the stripping tower can be moved up and down by the lifting device during the operation of the stripping tower. On the one hand, this can accelerate the mixing of the liquid in the stripping tower and improve the heating efficiency of the liquid in the stripping tower. On the other hand, it can also drive the top rod to move up and down and continuously squeeze the rubber liquid bladder. In this way, the elasticity of the rubber liquid bladder can be used to continuously deliver cooling water to the cooling pipes. This can cool down the base on the outside of the stripping tower and prevent the base from overheating and expanding, which would damage the internal stripping tower wall.

[0014] 2. By setting up a liquid inlet mechanism and a drive mechanism, the bubbles generated by the heating of the liquid inside the stripping tower can be used as power to continuously feed the liquid inside the stripping tower into the storage tank for storage. When the liquid pressure in the storage tank rises to the critical value of the pressure valve in the pressure pipe, the pressure valve opens, which generates a strong force to drive the float plate to move, thereby generating power to transport the water to the cooling pipe, greatly improving the energy utilization efficiency.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Reference Figure 1-5 A tall, thin-walled stripping tower mounting base includes a base 1 and a mechanism box 4. A hollow ring 2 is fixedly connected to the outer wall of the base 1, and multiple supports 8 are fixedly connected to the side wall of the hollow ring 2. Cooling pipes 3 are provided inside the hollow ring 2, and the cooling pipes 3 are distributed in a serpentine pattern around the hollow ring 2. A top rod 10 is slidably connected inside the mechanism box 4. A rubber liquid bladder 5 is provided inside the mechanism box 4. An inlet pipe 6 and an outlet pipe 7 connected to the rubber liquid bladder 5 are also provided inside the mechanism box 4. A one-way inlet valve and a one-way outlet valve are respectively installed in the inlet pipe 6 and the outlet pipe 7. The outlet pipe 7 is connected to the cooling pipe 3. Specifically, the inlet pipe 6 can be connected to a container with a cooling water source. The one-way inlet valve allows the cooling water to enter the rubber liquid bladder 5 only from the inlet pipe 6, while the one-way outlet valve allows the cooling water to flow unidirectionally from the rubber liquid bladder 5 to the cooling pipe 3.

[0023] A sealing sleeve 9 is provided outside the push rod 10, and the push rod 10 slides up and down along the sealing sleeve 9. The outer wall of the push rod 10 is tightly fitted with the inner wall of the sealing sleeve 9. A lifting device for raising and lowering the push rod 10 is installed outside the sealing sleeve 9. A first float plate 11 is fixedly connected to the upper end of the push rod 10. The first float plate 11 is fixedly connected to the upper end of the sealing sleeve 9 by a first spring 12.

[0024] The lifting device includes multiple suction cylinders 13 fixedly connected to the side wall of the sealing sleeve 9. Each suction cylinder 13 is connected to a storage cylinder 20 via a liquid inlet mechanism. The storage cylinder 20 is connected to a lifting cylinder 22 via a pressure pipe 21. A second float 23 is slidably connected inside the lifting cylinder 22, and a push rod 24 is fixedly connected to the upper end of the second float 23. A pressure valve is installed inside the pressure pipe 21. It should be noted that by installing a pressure valve inside the pressure pipe 21, a certain amount of liquid with a certain pressure is allowed to be stored in the storage cylinder 20 before being input into the lifting cylinder 22 through the pressure pipe 21. This generates sufficient power to push the second float 23 and the push rod 24 upwards, thereby pushing the first float 11 upwards. Furthermore, the storage cylinder 20 can also be made of a highly elastic rubber material. When high-pressure liquid is input into the storage cylinder 20, the storage cylinder 20 will expand. When the pressure valve inside the pressure pipe 21 opens, the storage cylinder 20 will instantly contract, rapidly squeezing out the internal liquid.

[0025] A third spring 25 is fixedly connected to the lower end of the second float 23, and the end of the third spring 25 away from the second float 23 is fixedly connected to the bottom of the lifting cylinder 22. A drain hole 26 is provided on the inner wall of the lifting cylinder 22, and the diameter of the drain hole 26 is smaller than the diameter of the pressure pipe 21.

[0026] The liquid inlet mechanism includes a suction pipe 18, a discharge pipe 19, and a piston 14. Both the suction pipe 18 and the discharge pipe 19 are connected to the suction cylinder 13. One-way shut-off valves are installed inside the suction pipe 18 and the discharge pipe 19. The piston 14 is slidably and sealingly connected inside the suction cylinder 13, and its movement is driven by a drive mechanism. It should be noted that the one-way shut-off valve in the suction pipe 18 restricts liquid flow only from the suction pipe 18 into the suction cylinder 13, while the one-way shut-off valve in the discharge pipe 19 restricts liquid flow only from inside the suction cylinder 13 into the upper storage cylinder 20.

[0027] The drive mechanism includes a drive rod 16 fixedly connected to the lower end of the piston 14, and a pneumatic plate 17 fixedly connected to the lower end of the drive rod 16. The piston 14 is connected to the inner bottom of the suction cylinder 13 via a second spring 15. It should be noted that, as... Figure 4 As shown, the lower end face of the pneumatic plate 17 is made into an arc-shaped structure. On the one hand, it can increase the contact area with the bubble and carry more bubbles, so that the bubbles can overcome the elastic force of the second spring 15 and push the pneumatic plate 17, the drive rod 16 and the piston 14 to move upward a certain distance. On the other hand, it will not excessively hinder the rise of the bubble, and the bubble can quickly escape to all sides on the arc-shaped surface of the pneumatic plate 17.

[0028] During the use of this device, if Figure 1As shown, the sealing sleeve 9 is installed through the bottom of the stripping tower 27 and welded to the outer wall of the stripping tower 27. Meanwhile, the components above the sealing sleeve 9 are installed inside the stripping tower 27.

[0029] When the liquid is separated by heating and evaporation inside the stripping tower 27, the bubbles formed by the evaporation of the liquid can continuously rise from the bottom of the stripping tower 27. The bubbles will continuously push the pneumatic plates 17 upward, moving the pneumatic plates 17 upward a certain distance. At the same time, the drive rod 16 and the piston 14 will move upward by the same distance. When the pneumatic plates 17 are in the interval between the bubbles, the second spring 15 can pull the piston 14 to make the pneumatic plates 17 move downward. In this way, under the combined action of the bubbles and the second spring 15, the piston 14 can move up and down (since the generation of bubbles is intermittent, it will intermittently push the pneumatic plates 17 upward).

[0030] When piston 14 moves downward, it draws liquid from stripping tower 27 into suction cylinder 13 through suction pipe 18. When piston 14 moves upward, it discharges the sucked liquid upward into storage cylinder 20 along discharge pipe 19. Therefore, as piston 14 moves up and down continuously, liquid is continuously fed into each storage cylinder 20 from stripping tower 27, and the pressure inside the storage cylinder 20 will rise accordingly. When the pressure inside a storage cylinder 20 rises to the critical value of the pressure valve in pressure pipe 21, the pressure valve in pressure pipe 21 opens, and the high-pressure liquid in storage cylinder 20 is instantly fed into lifting cylinder 22 through pressure pipe 21. Some liquid can flow back into stripping tower 27 through discharge hole 26 on the side wall of lifting cylinder 22. Figure 5 As shown, due to the small diameter of the drain hole 26, the liquid that rushes into the lifting cylinder 22 cannot be completely discharged from the drain hole 26 immediately. Therefore, the liquid will quickly accumulate in the lifting cylinder 22 and push the second float 23 and push rod 24 in the lifting cylinder 22 to move upward. When the push rod 24 moves upward to contact the first float 11 and continues to move upward, it can push the first float 11 to move upward a certain distance. Then the third spring 25 will pull the second float 23 downward. At the same time, the liquid in the lifting cylinder 22 will gradually be completely discharged back into the stripping tower 27 from the drain hole 26. After the first float 11 loses the push of the push rod 24, the first spring 12 can also pull the first float 11 downward to reset.

[0031] Therefore, the critical values ​​of the pressure valves in the pressure pipes 21 around the push rod 10 can be set to different values ​​from low to high. This allows each liquid storage cylinder 20 to sequentially input high-pressure liquid into the corresponding lifting cylinder 22, causing the push rods 24 in each lifting cylinder 22 to rise sequentially and push the first float 11 once in sequence. This design ensures that, on the one hand, enough pressure liquid can flow into the lifting cylinder 22, which can then powerfully push the second float 23 and push rods 24 to rise and push the first float 11. On the other hand, by setting the critical values ​​of the pressure valves in each pressure pipe 21 to different values ​​from low to high, the first float 11 can move up and down at a stable periodic interval, thereby pushing the push rod 10 up and down at a stable periodic interval. When the push rod 10 moves up and down stably, its lower end will continuously squeeze the rubber liquid bladder 5 in the mechanism box 4.

[0032] Whenever the rubber bladder 5 is squeezed, the internal cooling water can be discharged into the cooling pipe 3 through the outlet pipe 7. When the push rod 10 moves upward away from the rubber bladder 5, the rubber bladder 5 will inflate on its own, and its internal volume will increase. This will generate negative pressure and draw in cooling water through the inlet pipe 6 to replenish it. Therefore, when the push rod 10 continuously squeezes the rubber bladder 5, cooling water can be continuously input into the cooling pipe 3 through the outlet pipe 7. When the cooling water flows along the cooling pipe 3 surrounding the base 1, it can quickly carry the heat of the base 1 outward. This can cool down the base outside the stripping tower and prevent the base from overheating and deforming, which would damage the internal stripping tower wall.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
