Description

Technical Field

[0001] The utility model relates to the technical field of rectifying columns, and specifically relates to a liquid collector for a rectifying column. Background Technique

[0002] A rectifying column is a tower-type gas-liquid contact device mainly used for the rectification process. It is an extremely important mass transfer and heat transfer equipment in petrochemical production. By utilizing the different volatilities of each component in the mixture, the light components in the liquid phase are transferred to the gas phase, while the heavy components in the gas phase are transferred to the liquid phase, thereby achieving the efficient separation of the mixture to obtain high-purity products. Rectifying columns are mainly divided into two categories: plate columns and packed columns, each with its unique structure and operation mode. The liquid collector of a rectifying column is an important part inside the rectifying column, mainly used for collecting and redistributing the liquid flowing in the column.

[0003] The Chinese patent with the publication number CN202822832U discloses a liquid collector for a rectifying column and a rectifying column, including a liquid collecting tank surrounded by an inner ring wall, an outer ring wall and a bottom plate. A plurality of openings are provided on the bottom plate. A plurality of first overflow holes are arranged along the radial direction in the middle of the inner ring wall. The inner ring wall and the outer ring wall are conical, and the aperture of the upper end of the inner ring wall is smaller than that of the lower end, and the aperture of the upper end of the outer ring wall is larger than that of the lower end. The aperture of the opening on the bottom plate is smaller than the aperture of the first overflow hole.

[0004] Although the above scheme improves the rectification efficiency, the installation of this liquid collector requires professional tools, resulting in inconvenient installation, increasing the operation difficulty. At the same time, the cooling effect on the liquid is not sufficient, resulting in the substances separated by the rectifying column not being cooled and liquefied in time, reducing the purity and yield of the rectification products. Therefore, it does not meet the existing requirements. For this reason, we propose a liquid collector for a rectifying column. Summary of the Invention

[0005] The purpose of the utility model is to provide a liquid collector for a rectifying column to solve the problems of inconvenient installation and insufficient cooling effect of the liquid collector for a rectifying column proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A liquid collector for a rectifying column, including a liquid collector and a rectifying column main body. The liquid collector is arranged inside the rectifying column main body, and a hollow conical cylinder is arranged on the upper surface of the liquid collector;

[0007] It further includes a fixing frame, which is arranged on the inner wall of the rectifying column main body. A limiting groove is arranged on the upper side inside the fixing frame, and four limiting grooves are arranged at equal intervals in a ring shape. Pressing plates are arranged on the lower sides inside the limiting grooves;

[0008] It further includes a cooling part which is arranged inside the liquid collector. A cooling pipe is arranged inside the cooling part. An upper liquid collecting cavity is arranged on the upper side inside the cooling part, and the upper liquid collecting cavity is communicated with the liquid collector. A lower liquid collecting cavity is formed on the lower side inside the cooling part.

[0009] Preferably, L-shaped blocks are arranged on the outer walls of the liquid collector, and four L-shaped blocks are arranged at equal intervals in a circular shape. Limit blocks are arranged at the lower ends of the L-shaped blocks, and the limit blocks are all adapted to the limit grooves.

[0010] Preferably, a plurality of reset springs arranged in a rectangular array are arranged at the lower end inside the limit groove, and the pressing plate is connected to the limit groove through the reset springs.

[0011] Preferably, the upper liquid collecting cavity and the lower liquid collecting cavity are connected by a serpentine pipe, and the serpentine pipe is wound around the outer wall of the cooling pipe.

[0012] Preferably, a handle is installed at the upper end of the hollow conical cylinder.

[0013] Preferably, a liquid inlet pipe is arranged at one end of the cooling pipe, and one end of the liquid inlet pipe penetrates and extends to the outside of the cooling part.

[0014] Preferably, a liquid outlet pipe is arranged at the other end of the cooling pipe, and one end of the liquid outlet pipe penetrates and extends to the outside of the cooling part.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the present utility model, a fixing frame is installed on the inner wall of the rectification tower main body. When the liquid collector is installed inside the rectification tower main body, the limit blocks on the outer wall of the liquid collector are clamped into the limit grooves at the upper ends of the fixing frame. By rotating the limit blocks, they can slide in the limit grooves, so that the limit blocks can be limited by the limit grooves to prevent the limit blocks from coming out. At the same time, due to the elastic action of the reset springs, the pressing plate can move upward, and the pressing plate will make the limit blocks fit tightly with the limit grooves, further preventing the limit blocks from coming out, so that the installation of the liquid collector can be quickly completed without complex tools, and the operation is simple and convenient.

[0017] In the present utility model, a cooling part is arranged at the lower end of the liquid collector. A cooling pipe is used inside the cooling part. During use, coolant can be injected into the cooling pipe through the liquid inlet pipe and the liquid outlet pipe to realize the flow of the coolant. When the collected liquid enters the upper liquid collecting cavity through the through holes, the liquid can flow on the outer wall of the cooling pipe through the transportation of the serpentine pipe. Through the heat exchange with the cooling pipe, the temperature of the collected liquid can be quickly reduced, and the temperature of the liquid is significantly reduced when it is discharged from the lower liquid collecting cavity, thus effectively improving the cooling efficiency of the liquid collector.

[0018] The utility model provides a handle at the upper end of the hollow conical cylinder. When installing the liquid collector, the handle provides an operator with a stable and easy-to-grip fulcrum, so that when installing, disassembling or moving the liquid collector, its direction and position can be controlled more stably, effectively avoiding safety risks such as slipping and tipping due to improper operation.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1-4 The utility model provides a technical solution: a distillation tower liquid collector, comprising a liquid collector 1 and a distillation tower body 3, the liquid collector 1 is arranged inside the distillation tower body 3, and a hollow conical cylinder 16 is arranged on the upper surface of the liquid collector 1;

[0026] It also includes a fixing frame 6, which is arranged on the inner wall of the distillation tower body 3, and a limiting groove 7 is arranged on the upper side of the fixing frame 6, and four limiting grooves 7 are arranged in an annular shape and equidistantly, and an extrusion plate 8 is arranged on the lower side of the limiting grooves 7;

[0027] It also includes a cooling part 2, which is arranged inside the liquid collector 1. A cooling pipe 12 is arranged inside the cooling part 2. An upper liquid collecting chamber 10 is arranged on the upper side of the cooling part 2, and the upper liquid collecting chamber 10 is connected with the liquid collector 1. A lower liquid collecting chamber 13 is opened on the lower side of the cooling part 2.

[0028] When in use, the liquid collector 1 is easily moved into the distillation tower body 3 through the handle 17, and its limit block 5 is inserted into the limit groove 7 and connected by the L-shaped block 4. The limit block 5 slides in the limit groove 7 and is acted upon by the extrusion plate 8 and the return spring 9 to ensure a stable installation. The coolant enters the cooling pipe 12 through the liquid inlet pipe 14, and exchanges heat with the liquid in the liquid collector 1 at the serpentine pipe 11 while flowing through. After effectively reducing the liquid temperature, it is discharged from the liquid outlet pipe 15, thereby enhancing the cooling efficiency. The entire process does not require additional tools, and the operation is simple and quick.

[0029] See also Figure 3 and Figure 4 , the outer wall of the liquid collector 1 is provided with L-shaped blocks 4, and four L-shaped blocks 4 are arranged in an annular shape and are equidistantly distributed, and the lower end of the L-shaped blocks 4 is provided with limit blocks 5, and the limit blocks 5 are adapted to the limit grooves 7, and the four L-shaped blocks 4 are respectively connected to the limit blocks 5, so that the limit blocks 5 can be accurately and stably inserted into the limit grooves 7, further enhancing the connection strength between the liquid collector and the distillation tower body;

[0030] See also Figure 4 , a plurality of return springs 9 distributed in a rectangular array are arranged at the lower end of the limiting groove 7, and the extrusion plate 8 is connected to the limiting groove 7 through the return spring 9. The return spring 9 can provide a buffer when the limiting block 5 is pressed, thereby reducing the impact force during the installation process. At the same time, after the handle is released, the elastic restoring force of the spring is used to push the extrusion plate 8 upward, so that the limiting block 5 and the limiting groove 7 are closely fitted, thereby ensuring the firmness of the installation of the liquid collector;

[0031] See also Figure 2 The upper liquid collecting chamber 10 and the lower liquid collecting chamber 13 are connected by a serpentine tube 11, and the serpentine tube 11 is wound around the outer wall of the cooling tube 12. The design of the serpentine tube 11 increases the path length of the liquid during the flow process, thereby improving the efficiency of heat exchange with the cooling tube 12. The serpentine tube 11 is close to the cooling tube 12, making the heat transfer more rapid and sufficient, and effectively reducing the temperature of the collected liquid;

[0032] See also Figure 1 and Figure 2 A handle 17 is installed at the upper end of the hollow conical cylinder 16, and the handle 17 provides a convenient point of force for the operator, making the installation, removal and movement of the liquid collector 1 easier and more efficient;

[0033] See also Figure 2, one end of the cooling pipe 12 is provided with a liquid inlet pipe 14, and one end of the liquid inlet pipe 14 penetrates and extends to the outside of the cooling part 2. The liquid inlet pipe 14 can conveniently introduce the coolant into the inside of the cooling pipe 12 to realize the circulating supply of the coolant. At the same time, the external extension design of the liquid inlet pipe 14 is also convenient for connecting with an external cooling system;

[0034] Please refer to Figure 2 , the other end of the cooling pipe 12 is provided with a liquid outlet pipe 15, and one end of the liquid outlet pipe 15 penetrates and extends to the outside of the cooling part 2. The liquid outlet pipe 15 can timely discharge the coolant that has absorbed heat from the cooling part 2 to ensure the continuity and high efficiency of the cooling process.

[0035] Working principle: During use, hold the handle 17 to move the liquid collector 1 into the inside of the rectification tower main body 3, so that the limit block 5 is stuck into the corresponding limit groove 7. Press the liquid collector 1 downward through the handle 17. Through the connection of the L-shaped block 4, the limit block 5 can squeeze the pressing plate 8 inside the limit groove 7. The pressing plate 8 will compress the return spring 9. At this time, the liquid collector 1 can be rotated, and the limit block 5 will slide synchronously in the limit groove 7. The limit groove 7 can limit the limit block 5 to prevent it from coming out. At the same time, when the handle 17 is released, under the elastic recovery action of the return spring 9, the pressing plate 8 will move upward, thereby squeezing the limit block 5 in the limit groove 7, making the limit block 5 firmly fit with the limit groove 7, further preventing the limit block 5 from coming out. Thus, the liquid collector 1 can be installed on the fixing frame 6 without using additional tools, and the operation is simple and convenient. When the collected liquid enters the upper liquid collecting cavity 10 through the through hole, the operator can input the coolant into the inside of the cooling pipe 12 through the liquid inlet pipe 14, and then discharge the coolant through the liquid outlet pipe 15 to make the coolant flow. The liquid entering the upper liquid collecting cavity 10 will enter the inside of the lower liquid collecting cavity 13 through the serpentine pipe 11. When the collected liquid passes through the serpentine pipe 11, it will exchange heat with the coolant in the cooling pipe 12, and then the temperature of the collected liquid can be effectively reduced, effectively improving the cooling efficiency of the liquid collector 1.
