A T-type solid valve for a distillation column

Abstract

This utility model discloses a T-type fixed valve for a distillation column, comprising: an inner tray of the distillation column, with a T-type fixed valve fixedly inserted into one end of the inner tray. Multiple sets of T-type fixed valves are uniformly fixed and inserted into one end of the inner tray. In this utility model, the multiple sets of air holes on the inner tray allow for initial segmentation of the rising gas. The gas flows out through these air holes and enters below the top cover plate of the fixed valve. Firstly, the rising gas is better dispersed by the multiple sets of lateral semi-circular grooves. Secondly, the gas flows out through the air passages on the middle cover plate, and is further dispersed by the multiple sets of top plate connecting strips and the obstruction of the top plate on the cover plate. This results in better gas dispersion, allowing the gas to be more evenly dispersed into the liquid layer on the tray, creating a better gas-liquid contact state.

Description

Technical Field

[0001] This utility model relates to the technical field of distillation column equipment, specifically a T-type solid valve for distillation columns. Background Technology

[0002] A distillation column is a tower-type gas-liquid contact device used for distillation. It is also known as a distillation tower and is widely used in petroleum, chemical, light industry, food and other fields. A distillation column is usually composed of a column body, trays or packing, reboiler, condenser and other parts. Multiple sets of T-shaped solid valves are fixedly installed on the inner tray to achieve the effect of blocking and separating the gas.

[0003] The rising gas enters from the bottom of the T-type solid valve, passes through the channel between the valve leg and the tray, and then flows out from the periphery of the cover plate. After the gas disperses into the liquid layer, it forms numerous bubbles, which greatly increases the contact area between the gas and liquid phases. However, the existing T-type solid valves in distillation columns are not very effective at separating and blocking the gas, making them inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a T-type solid valve for distillation columns, which is inconvenient to use due to its poor gas separation and blocking effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a T-type fixed valve for a distillation column, comprising: an inner tray of the distillation column, wherein a T-type fixed valve is fixedly inserted into one end of the inner tray of the distillation column, and the number of T-type fixed valves is configured in multiple sets, wherein the multiple sets of T-type fixed valves are uniformly fixedly inserted into one end of the inner tray of the distillation column.

[0006] As a further embodiment of this utility model: the inner tray of the distillation column includes an inner tray body, one end of which is provided with a gas hole, and a fixed valve insertion slot is provided at the end of the inner tray body near the gas hole. The number of gas holes and fixed valve insertion slots on the inner tray is multiple, and every three sets of gas holes on the inner tray are adapted to four sets of fixed valve insertion slots.

[0007] As a further embodiment of this utility model: the T-type fixed valve includes a fixed valve upper cover plate, a fixed valve limiting support plate is fixedly provided at one lower end of the fixed valve upper cover plate, and a plug-in bent fixing foot is fixedly provided at one lower end of the fixed valve limiting support plate.

[0008] As a further embodiment of this utility model: a lateral dividing semi-circular groove is provided on one side of the upper cover plate of the fixed valve, and an air passage groove is provided through the middle of the upper cover plate inside the fixed valve. A top plate connecting strip is fixedly provided on one side of the air passage groove on the upper cover plate, and an upper air top plate is fixedly provided on one side of the top plate connecting strip.

[0009] As a further improvement of this utility model: multiple sets of the fixed valve limiting support plate and the plug-in bending fixing foot are provided, and every two sets of the fixed valve limiting support plate and four sets of the plug-in bending fixing foot are adapted to one set of the fixed valve upper cover plate for fixation.

[0010] As a further embodiment of this utility model: multiple sets of the side-divided semi-circular grooves are provided on both sides of the upper cover plate of the fixed valve, and multiple sets of the top plate connecting strips are fixedly provided between the upper cover plate of the fixed valve and the gas top plate on the cover plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the gas rising below can be initially divided by the multiple sets of air holes on the inner tower plate. After flowing out through the multiple sets of air holes on the inner tower plate, the gas enters the area below the fixed valve cover plate. At this point, the gas is first divided by the multiple sets of side-divided semi-circular grooves, which can make the rising gas form a better dispersion effect. The gas can also flow out through the air passage groove on the middle cover plate, and the gas is further dispersed by the multiple sets of top plate connecting strips and the air top plate on the cover plate. This can achieve a better gas dispersion effect, allowing the gas to be more evenly dispersed into the liquid layer on the tower plate, forming a better gas-liquid contact state.

[0013] In this invention, the four sets of plug-in bent fixing feet inside the T-type fixed valve are aligned with the plug-in slot of the fixed valve and inserted until the fixed valve limit support plate is attached to the inner plate of the distillation column. At this time, the T-type fixed valve can be quickly fixed and installed by bending the four sets of plug-in bent fixing feet. Similarly, the T-type fixed valve can be easily disassembled, which facilitates the disassembly and replacement of the T-type fixed valve in the future. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figure 1 and Figure 2 In this embodiment of the utility model, a T-type fixed valve for a distillation column includes: an inner tray 1 of the distillation column, a T-type fixed valve 2 fixedly inserted into one end of the inner tray 1 of the distillation column, and multiple sets of T-type fixed valves 2 are provided, with multiple sets of T-type fixed valves 2 being uniformly fixedly inserted into one end of the inner tray 1 of the distillation column.

[0022] Reference Figure 3The inner tray 1 of the distillation column includes an inner tray body 10. One end of the inner tray body 10 is provided with a gas hole 11. The inner tray body 10 is provided with a fixed valve insertion slot 12 at the end near the gas hole 11. There are multiple sets of gas holes 11 and fixed valve insertion slots 12. Every three sets of gas holes 11 on the inner tray are matched with four sets of fixed valve insertion slots 12.

[0023] Reference Figure 4 The T-type fixed valve 2 includes a fixed valve upper cover plate 20. A fixed valve limiting support plate 21 is fixedly installed at one end of the fixed valve upper cover plate 20. A plug-in bent fixing foot 22 is fixedly installed at one end of the fixed valve limiting support plate 21. There are multiple sets of fixed valve limiting support plates 21 and plug-in bent fixing feet 22. Every two sets of fixed valve limiting support plates 21 and four sets of plug-in bent fixing feet 22 are adapted to one fixed valve upper cover plate 20 and fixed. The plug-in bent fixing feet 22 are adapted to be inserted into the fixed valve plug-in through groove 12.

[0024] Using the above solution: by aligning the four sets of plug-in bent fixing feet 22 inside the T-type fixed valve 2 with the plug-in slot 12 of the fixed valve and inserting them until the fixed valve limit support plate 21 is attached to the inner plate 10 of the distillation column, the T-type fixed valve 2 can be quickly fixed and installed by bending the four sets of plug-in bent fixing feet 22. Similarly, the T-type fixed valve 2 can be easily disassembled, which facilitates the disassembly and replacement of the T-type fixed valve 2 in the future.

[0025] Reference Figure 4 The upper cover plate 20 of the fixed valve has a side-divided semi-circular groove 23 on one side. The upper cover plate 20 has a through-hole air passage 24 in the middle. A top plate connecting strip 25 is fixedly installed at one end of the air passage 24 on the upper cover plate. A top plate air passage 26 is fixedly installed at one end of the top plate connecting strip 25. Multiple sets of side-divided semi-circular grooves 23 are opened on both sides of the upper cover plate 20 of the fixed valve. Multiple sets of top plate connecting strips 25 are fixedly installed between the upper cover plate 20 of the fixed valve and the top plate air passage 26 on the upper cover plate.

[0026] The above scheme achieves the following: the gas rising below can be initially divided by the multiple sets of gas holes 11 on the inner tower plates. After flowing out through the multiple sets of gas holes 11 on the inner tower plates, the gas enters below the fixed valve cover plate 20. At this time, the gas is first divided by the multiple sets of side-dividing semi-circular grooves 23, which can make the rising gas form a better dispersion effect. The gas can also flow out through the gas passage groove 24 on the middle cover plate, and the gas is further dispersed by the multiple sets of top plate connecting strips 25 and the gas top plate 26 on the cover plate. This can achieve a better gas dispersion effect, and make the gas more evenly dispersed into the liquid layer on the tower plate, forming a better gas-liquid contact state.

[0027] The working principle of this utility model is as follows: During use, the four sets of bent fixing feet 22 inside the T-type fixed valve 2 are aligned with the fixing valve insertion slot 12 and inserted until the fixing valve limiting support plate 21 is in contact with the inner column plate 10 of the distillation column. At this point, the T-type fixed valve 2 can be quickly fixed by bending the four sets of bent fixing feet 22. Similarly, the T-type fixed valve 2 can be easily disassembled, facilitating its later replacement. During use, the multiple sets of gas holes 11 on the inner column plate allow for preliminary segmentation of the rising gas. At this time, the gas flows out through the gas holes 11 on the multiple sets of inner tower plates and enters below the fixed valve cover plate 20. First, the gas is divided by the multiple sets of side-divided semi-circular grooves 23, which can make the rising gas form a better dispersion effect. The gas can also flow out through the gas passage groove 24 on the middle cover plate, and the gas is further dispersed by the multiple sets of top plate connecting strips 25 and the gas top plate 26 on the cover plate. This can achieve a better gas dispersion effect, and make the gas more evenly dispersed into the liquid layer on the tower plate, forming a better gas-liquid contact state.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
