TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical equipment, and the specific field is a rectifying assembly of rectifying tower. BACKGROUND

[0002] In related technologies, rectification is a widely used separation technology in chemical production, and its basic principle is to use the different volatility of each component in the mixture at different temperatures to realize the separation of components through repeated evaporation and condensation process. In the rectifying tower, the rectifying assembly is the key part to realize effective separation, which usually includes tower plate or filler structure, etc.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies:

[0004] The traditional rectifying tower assembly design has some shortcomings, such as uneven liquid flow, poor gas rising channel, low mass transfer efficiency, etc. These problems affect the rectification effect and efficiency. At the same time, the structure design of the traditional rectifying tower assembly is often not compact, occupies a large space, and it is difficult to maintain and replace parts. UTILITY MODEL CONTENT

[0005] The purpose of the utility model is to provide a rectifying assembly of rectifying tower to solve the problems raised in the background technology.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a rectifying assembly of rectifying tower, which includes multiple key parts, including tower plate assembly, filler assembly, gas distribution plate, liquid distributor and gas collector. The tower plate assembly is composed of at least two tower plates, and multiple through holes are uniformly distributed on each tower plate. These through holes are staggered, so as to form a liquid flow channel and a gas rising channel between the adjacent two tower plates. The filler assembly is located above and below the tower plate assembly, which is composed of multiple filler layers, each of which is composed of porous filler material to promote the effective contact between gas and liquid. Between the adjacent two filler layers, a gas distribution plate is arranged to ensure uniform distribution of gas. The liquid distributor is located above the uppermost tower plate of the tower plate assembly, and its main function is to uniformly distribute the liquid to the entire tower plate assembly to optimize the rectification process. The gas collector is arranged above the uppermost filler layer of the filler assembly, and its purpose is to collect the gas rising from the filler assembly to ensure the effective collection and subsequent treatment of the gas.

[0007] Further, the through holes on the tower plate assembly are carefully designed as circular holes, and the hole diameter is accurately set between 5 to 15 mm. This meticulous design not only helps the smooth flow of liquid and gas, but also effectively maintains the structural strength of the tower plate, ensuring the reliability and efficiency of the tower plate in industrial applications.

[0008] In the aspect of packing components, the selection of packing materials is crucial as it directly relates to the efficiency and effectiveness of the entire distillation process. These materials can be in the form of wire mesh, ceramic rings, or plastic rings, each with unique physical and chemical properties. Wire mesh is favored for its durability and good thermal conductivity;

[0009] Ceramic rings are widely used due to their excellent high-temperature resistance, corrosion resistance, and porous structure;

[0010] Plastic rings are an economical choice due to their lightweight, low cost, and corrosion resistance. The common feature of these materials is their good porosity, which allows them to provide a large surface area, increasing the opportunity for gas-liquid contact and improving distillation efficiency. Their corrosion resistance ensures that the packing components remain stable in the face of various chemicals, preventing damage from chemical reactions, thus adapting to different distillation conditions and ensuring the smooth progress of the entire distillation process.

[0011] The gas distribution plate, as a key component in the gas flow process, is designed with a perforated plate structure, with each hole carefully designed to be between 1 to 5 millimeters in diameter.

It not only needs to precisely control the flow of liquid, but its design directly affects the efficiency and uniformity of the entire distillation process. The upper part of the liquid distributor is carefully designed with several nozzles, which are cleverly arranged in a circular array. This circular array layout ensures that the liquid can be sprayed onto the lower tray assembly in a very uniform manner. Through this uniform spraying, the liquid can form a thin and uniform liquid film on the tray, which not only helps to improve the efficiency of the distillation process, but also ensures that the distillation effect of each part remains consistent, thereby achieving the purpose of improving the uniformity and efficiency of the overall distillation process.

[0013] Compared with the prior art, the beneficial effects of the present utility model are: improving the distillation efficiency, by setting multiple through holes on the tray assembly and staggering the through holes of adjacent two layers of trays, an effective liquid flow channel and gas rising channel can be formed, thereby improving the mass transfer efficiency in the distillation process.

[0014] Enhancing the uniformity of liquid distribution, the setting of the liquid distributor can ensure that the liquid is evenly distributed to the tray assembly, avoiding uneven distribution of the liquid on the tray, thereby improving the distillation effect.

[0015] The gas distribution is optimized, the gas distribution plate can make the gas uniformly distributed between the filler layers, reduces the gas short circuit phenomenon, and improves the contact efficiency of the gas and the liquid.

[0016] The gas collection efficiency is improved, the gas collector can effectively collect the gas rising from the filler assembly, reduces the gas escape, and improves the utilization rate of the gas.

[0017] The adaptability is strong, the filler material in the filler assembly can be metal wire mesh, ceramic ring or plastic ring, these materials have different physical and chemical properties, and appropriate filler material can be selected according to different rectification requirements, and the adaptability of the rectifying tower is improved.

[0018] The structure is compact, the tray assembly, the filler assembly, the liquid distributor and the gas collector are integrated in the rectifying tower, the compact structure is realized, and the space is saved.

[0019] The maintenance is convenient, due to the structural design of the tray assembly and the filler assembly, the maintenance and replacement of parts of the rectifying tower are more convenient and fast. DETAILED DESCRIPTION

Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the utility model.

[0024] Please refer to Figures 1-2The utility model provides a technical scheme: a rectifying assembly of rectifying column, the assembly contains multiple key parts, including tray assembly 1, packing assembly 2, gas distribution plate 3, liquid distributor 4 and gas collector 5, tray assembly 1 is formed by at least two layers of trays, multiple through holes 6 are uniformly distributed on each layer of trays, these through holes are staggered, to form the passage of liquid flow and the passage of gas rising between the adjacent two layers of trays, packing assembly 2 is located above and below tray assembly 1, it is formed by multiple packing layers, each packing layer is composed of porous packing material, to promote the effective contact of gas and liquid, gas distribution plate 3 is arranged between the adjacent two layers of packing layers, to ensure that gas is uniformly distributed, liquid distributor 4 is located above the uppermost tray of tray assembly 1, its main function is to uniformly distribute liquid to the whole tray assembly, to optimize the rectifying process, gas collector 5 is arranged above the uppermost packing layer of packing assembly 2, its purpose is to collect the gas rising from packing assembly 2, to ensure the effective collection and subsequent processing of gas.

[0025] Further, the through hole 6 on the tray assembly 1 is carefully designed as a circular hole, and the hole diameter is accurately set to be between 5 to 15 mm. This meticulous design not only helps the smooth flow of liquid and gas, but also effectively maintains the structural strength of the tray, ensuring the reliability and efficiency of the tray in industrial applications.

[0026] In terms of packing assembly 2, the selection of packing material is crucial as it directly relates to the efficiency and effectiveness of the entire rectifying process. These materials can be in the form of wire mesh, ceramic rings, or plastic rings, each with unique physical and chemical properties. Wire mesh is favored for its durability and good thermal conductivity;

[0027] Ceramic rings are widely used due to their excellent high-temperature resistance, corrosion resistance, and porous structure;

[0028] Plastic rings are an economical choice due to their lightweight, low cost, and corrosion resistance. The common characteristic of these materials is their good porosity, which allows them to provide a large surface area, increasing the opportunity for gas-liquid contact and improving rectifying efficiency. At the same time, their corrosion resistance ensures that the packing assembly remains stable in the face of various chemicals, without being damaged by chemical reactions, thus adapting to different rectifying conditions and ensuring the smooth progress of the entire rectifying process.

[0029] Gas distribution plate 3, as a key component in the gas flow process, is designed in the form of a perforated plate, with each hole carefully designed to be between 1 to 5 mm in diameter. This fine design ensures that gas can be evenly distributed between the packing layers, effectively improving the efficiency of the rectifying process.

[0030] In the design of the rectifying column, the liquid distributor 4 plays a crucial role. It not only needs to precisely control the flow of liquid, but also its design directly affects the efficiency and uniformity of the entire rectification process. The upper part of the liquid distributor 4 is carefully designed with several nozzles 7, which are ingeniously arranged in a circular array. This circular array layout ensures that the liquid can be sprayed onto the lower tray assembly 1 in a very uniform manner. Through this uniform spraying, the liquid can form a thin and uniform liquid film on the tray, which not only helps to improve the efficiency of the rectification process, but also ensures that the rectification effect of each part remains consistent, thereby achieving the purpose of improving the uniformity and efficiency of the overall rectification process.

[0031] Working principle: When the utility model works, liquid mixture enters from the top of the column, first passes through the liquid distributor 4, and the liquid distributor uniformly distributes the liquid on the uppermost tray. The nozzles 7 on the liquid distributor are distributed in a circular array, ensuring uniform distribution of the liquid.

[0032] The liquid flows on the tray assembly 1 and flows to the next layer of trays through the through holes 6 on the trays. Due to the staggered arrangement of the through holes of the adjacent two layers of trays, the liquid is fully contacted with the rising gas during the flow process, realizing mass transfer and heat transfer.

[0033] The packing assembly 2 is located above and below the tray assembly and is composed of multiple layers of packing layers. Each layer of packing layer is composed of porous packing material such as metal mesh, ceramic ring or plastic ring. The packing layer increases the gas-liquid contact area, further promoting mass transfer and heat transfer.

[0034] Gas distribution plates 3 are provided between adjacent two layers of packing layers, and the gas distribution plates are perforated plates with a pore size of 1-5 mm, ensuring that the gas rises uniformly through the packing layers.

[0035] During the rising process of the gas, the gas is fully contacted with the falling liquid through the through holes on the packing layers and the trays, realizing the separation of components. The lighter components rise with the gas, and the heavier components descend with the liquid.

[0036] The gas collector 5 is located above the uppermost layer of the packing assembly and is used to collect the gas rising from the packing assembly. The collected gas can be further condensed or treated to separate the required components.

[0037] At the bottom, the heavier liquid components are collected, and the lighter components are discharged through the top of the column.

[0038] Throughout the process, by controlling the temperature and pressure in the column, as well as the flow of liquid and gas, the rectification process can be optimized, improving the separation efficiency and product purity.
