Description

Technical Field

[0001] This utility model relates to the field of distillation tower technology, specifically a new type of energy-saving and consumption-reducing distillation tower. Background Technology

[0002] Distillation, a common material separation method in industries such as chemical engineering, pharmaceuticals, and environmental engineering, has long relied on gas-liquid mass transfer to separate mixed components. In traditional distillation column structures, common packing types include stepped rings, Pall rings, and mesh packing. These packings are typically arranged inside the column in a stacked or loose manner to enhance the gas-liquid contact area and improve separation efficiency.

[0003] However, existing distillation column structures still have the following typical problems in terms of packing design:

[0004] Limited mass transfer efficiency: Although traditional ring or sheet packings have a certain specific surface area, their irregular shape and loose arrangement lead to uneven distribution of gas-liquid flow paths. In particular, gas short-circuiting or liquid leaching are prone to occur in local areas, which reduces the overall mass transfer efficiency.

[0005] High energy consumption: Due to the significant resistance to gas flow caused by the packing structure, a high-power fan is required for gas transport during tower operation, resulting in high overall system energy consumption. Furthermore, the shape of some packing materials hinders uniform liquid penetration, further exacerbating energy waste.

[0006] In summary, the existing distillation column packing structure has significant shortcomings in terms of mass transfer efficiency, gas-liquid distribution uniformity, and system energy consumption control. There is an urgent need for an improved distillation column with a more optimized structure, more stable operation, higher mass transfer efficiency, and more significant energy-saving effect. Utility Model Content

[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted by this utility model is as follows: a novel energy-saving and consumption-reducing distillation column, comprising: a distillation column body, an aeration assembly, a liquid distribution assembly, and several packing layers. The surface of the distillation column body is provided with a sealing door, and several heating plates are fixedly installed on the inner side of the distillation column body. Each packing layer and heating plate is alternately distributed and fixed on the inner side of the distillation column body. The aeration assembly includes a blower and an air distribution pipe connected to the blower port. One side of the air distribution pipe is provided with an exhaust port facing the inner side of each packing layer. The liquid distribution assembly includes a liquid distribution pipe and several spray pipes fixed to the top surface of the heating plates. The liquid distribution pipe is used to connect to the spray pipe and its surface is connected to the end of the spray pipe.

[0009] In a preferred embodiment, the present invention can be further configured such that: the filler layer includes a metal mesh box and filler particles arranged inside the metal mesh box, the filler particles are spherical and stacked inside the metal mesh box, and the gaps between the filler particles form a mixed contact flow channel for liquid flow and air flow.

[0010] In a preferred embodiment, the present invention can be further configured such that the spray pipe is in the shape of a zigzag bend and has several through holes on its surface for uniform overflow of the spray liquid.

[0011] In a preferred embodiment, the present invention can be further configured such that: a return liquid tank is provided on the bottom surface of the internal cavity of the distillation column, and the end of the return liquid tank is connected to a circulating pump group connected to a liquid distribution pipe.

[0012] In a preferred embodiment, the present invention can be further configured such that: a plurality of uniformly distributed liquid holes are formed on the surface of the heating plate, the liquid holes are raised, and an electric heating component is embedded inside the heating plate.

[0013] Specifically, the liquid holes arranged on the surface of the heating plate are used for the downward flow of the spray liquid, and the raised structure is used to intercept part of the spray liquid and heat it on its surface, so as to achieve uniform heating of the spray liquid and thus improve the uniformity of the internal temperature of the distillation column.

[0014] In a preferred embodiment, the present invention can be further configured such that the outer surface of the distillation column is covered with an insulation layer to reduce heat loss.

[0015] In a preferred embodiment, the present invention can be further configured such that a noise reduction device is provided between the fan and the air distribution pipe to reduce the noise generated during air delivery and improve the environmental friendliness of the device.

[0016] The beneficial effects achieved by this utility model are as follows:

[0017] 1. In this invention, the filler particles filling the filler layer adopt a spherical granular structure and are arranged in a stacked manner within a metal mesh box. This structure, through the numerous natural gaps formed between the filler particles, constructs a continuous and irregular liquid-gas mixing and contact channel, thereby significantly enhancing the gas-liquid contact area and improving mass transfer efficiency.

[0018] 2. In this invention, the spherical packing particles are arranged closely but without excessive clogging, which ensures smooth liquid flow and avoids excessive gas resistance, effectively reducing energy consumption during system operation. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a novel energy-saving and consumption-reducing distillation tower.

[0029] Combination Figures 1-5 As shown, this utility model provides a novel energy-saving and consumption-reducing distillation column, comprising a distillation column body 100, an aeration assembly 200, a liquid distribution assembly 300, and several packing layers 400. The distillation column body 100 is a hollow vertical structure, and its outer surface is provided with a sealing door 110 for easy opening and maintenance. Inside the distillation column body 100, several horizontally distributed heating plates 120 are arranged vertically to support the packing layers.

[0030] The filler layer 400 includes a metal mesh box and filler particles filled inside the mesh box. The filler particles have a spherical particle structure and are arranged in a stacked manner to fill the interior of the metal mesh box, thereby enhancing the gas-liquid exchange efficiency and reducing energy consumption.

[0031] The heating plates 120 and the packing layers 400 are alternately arranged in the distillation column body 100 to form a three-dimensional distillation stage structure. Each heating plate 120 has several spray pipes 320 installed on its top surface. The spray pipes 320 have a zigzag bent pipe structure and several through holes on their surface for uniformly spraying spray liquid onto the packing layer below.

[0032] The liquid distribution assembly 300 includes a liquid distribution pipe 310 disposed on the side of the tower body, which is used to guide the spray liquid into the tower body and is connected to the ends of each spray pipe 320 to realize multi-layer delivery of the spray liquid.

[0033] A return tank is provided at the bottom of the distillation column 100 to collect the liquid flowing down from the inside of the column; the outlet of the return tank is connected to a circulation pump set and forms a closed loop with the liquid distribution pipe 310 to build an efficient liquid recovery system.

[0034] To improve the heating efficiency of the spray liquid and the temperature uniformity within the tower, the surface of the heating plate 120 is provided with several liquid holes. These holes have a raised structure to control the liquid seepage path and create a partial liquid retention area. Furthermore, an electric heating element is embedded inside the heating plate 120 to heat the retained spray liquid, promoting uniform heating.

[0035] Furthermore, in order to reduce heat loss and improve energy utilization efficiency, the outer surface of the distillation column body 100 is covered with a heat insulation layer to effectively isolate the influence of external environmental temperature differences.

[0036] Regarding the gas distribution structure, the aeration component 200 includes a blower 210 and an air distribution pipe 220 connected to its air outlet. The air distribution pipe 220 is distributed along the interior of the tower body, and has multiple exhaust ports 221 inside the opposing packing layer 400 on one side to improve the uniformity of gas diffusion in the distillation tower. In order to reduce operating noise, a silencer is provided between the blower 210 and the air distribution pipe 220 to enhance the environmental adaptability of the equipment.

[0037] Working principle and usage process of this utility model:

[0038] The liquid distribution assembly 300 evenly distributes the spray liquid to multiple packing layers 400. The liquid is introduced through the liquid distribution pipe 310, guided in a zigzag pattern through multiple spray pipes 320, and sprayed onto the surface of the packing through through holes to achieve uniform liquid distribution.

[0039] Under the influence of gravity, the liquid flows downwards through the stacked packing particles. The spherical particle structure of the packing layer 400 provides a large specific surface area, ensuring sufficient contact between the liquid and gas and improving mass transfer efficiency.

[0040] The aeration component 200 generates airflow through the blower 210. The gas is transported along the air distribution pipe 220 and sprayed out through multiple exhaust ports 221 aligned with the packing layer, realizing the airflow from bottom to top and forming countercurrent contact with the liquid to enhance the separation effect.

[0041] Each heating plate 120 not only supports the packing layer, but also has liquid holes to assist liquid permeation. Some liquid is retained on the surface of the heating plate due to the protruding liquid hole structure. The embedded electric heating component heats the retained liquid, effectively improving the uniformity of the overall temperature field and stabilizing the separation conditions.

[0042] The spray liquid flows into the return tank from the bottom of the tower and is then pumped back to the distribution pipe 310 by the circulating pump unit, forming a closed-loop system that greatly reduces liquid waste.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
