Description

Technical Field

[0001] This utility model relates to the field of distillation equipment technology, and in particular to a distributor for distillation air. Background Technology

[0002] Air distillation is an industrial process that separates air based on the differences in boiling points of its components. It yields high-purity oxygen, nitrogen, and other products, and is widely used in various fields. The use of a distributor is crucial. In terms of improving separation efficiency, it ensures uniform air distribution within the distillation column, optimizes gas-liquid contact, and promotes more thorough gas-liquid exchange, thereby enhancing product purity. Regarding operational stability, it prevents abnormal phenomena such as flooding and channeling, ensuring stable product composition and purity at the top and bottom of the column. This meets the stringent quality requirements of medical oxygen production, making it indispensable for the efficient and stable operation of distilled air.

[0003] Traditional distributors are relatively simple, mostly consisting of basic flow guiding devices such as perforated plates. They cannot achieve uniform gas transmission to the equipment in use, which can lead to incomplete gas-liquid bonding, resulting in poor distillation reaction and reduced practicality of the distributor. Therefore, a distributor for distillation air is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a distributor for distillation air, which aims to improve the problem that the existing technology has a simple flow guiding structure and a single function, which cannot achieve efficient gas-liquid combination and thus reduces the practicality of the distributor.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a distributor for distillation air, comprising a fixed plate, a guide box fixedly connected to the upper surface of the fixed plate, a flow slope provided on one side of the guide box, multiple air outlet components installed on the upper surface of the guide box, an auxiliary component installed on one side of the outer wall of the guide box, and left and right symmetrical liquid outlet guide components fixedly connected to the inner wall of the fixed plate.

[0006] The auxiliary component includes a spiral tube, one end of which is fixedly connected to one side of the outer wall of the guide box, and multiple air outlet tubes are fixedly connected to the outer wall of the spiral tube.

[0007] Furthermore, the air outlet assembly includes a trapezoidal box, the lower surface of which is fixedly connected to the upper surface of the guide box, and a plurality of connecting pipes are fixedly connected to the upper surface of the trapezoidal box.

[0008] Furthermore, the liquid guiding assembly includes two liquid guiding slopes, the outer walls of which are fixedly connected to the inner wall of the fixed disk, and the fixed disk has multiple liquid outlet holes through it.

[0009] Furthermore, an upper top plate is provided above the connecting pipe, and multiple air vents are provided through the interior of the upper top plate. An extension component is fixedly connected to the lower surface of the upper top plate, and a limit component is installed on the outer wall of the upper top plate.

[0010] Furthermore, the extension assembly includes an extension tube one, the upper surface of which is fixedly connected to the interior of an upper top plate, and an extension tube two is fixedly connected to the side of the upper top plate away from the extension tube one. The outer wall of the extension tube one is slidably connected to the inner wall of the connecting tube one, and the outer wall of the extension tube two is slidably connected to the inner wall of the spiral tube.

[0011] Furthermore, the limiting component includes an extension column, one end of which is fixedly connected to the outer wall of the upper top plate, and a limiting plate is fixedly connected to the other end of the extension column. A sleeve is slidably connected to the outer wall of the limiting plate, an arc-shaped plate is fixedly connected to one side of the outer wall of the sleeve, and a spring is slidably connected inside the sleeve.

[0012] Furthermore, both extension tube one and extension tube two are disposed on the inner wall of the air outlet, and the air outlet is used to install extension tube one and extension tube two.

[0013] Furthermore, one end of the spring is fixedly connected to one side of the inner wall of the sleeve, and the other end of the spring is fixedly connected to one side of the outer wall of the limiting plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the gas is guided into the trapezoidal box through the guide box, and then the gas is evenly distributed into the equipment through multiple connecting pipes through the trapezoidal box. At the same time, the gas is further diverted to the vicinity of the outlet pipe through the spiral tube, so that the gas is evenly distributed into the equipment, achieving the effect of efficient diversion and thus improving the practicality of the distributor.

[0016] 2. In this utility model, by lifting the top plate, the extension tube one and extension tube two are driven to move. Through the movement of the extension tube one and extension tube two, the height can be finely adjusted according to the equipment being used. At this time, the reaction force of the spring is used to drive the sleeve to extend and retract, so that the arc plate is tightly attached to the inner wall of the equipment being used, thereby achieving the effect of fixing the top plate and improving the practicality of the distributor.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 4 An embodiment of this utility model is provided: a distributor for distillation air, including a fixed plate 1, a guide box 2 fixedly connected to the upper surface of the fixed plate 1, a flow slope 3 provided on one side of the guide box 2, multiple air outlet components installed on the upper surface of the guide box 2, an auxiliary component installed on one side of the outer wall of the guide box 2, and left and right symmetrical liquid outlet guide components fixedly connected to the inner wall of the fixed plate 1.

[0025] The auxiliary components include a spiral tube 6, one end of which is fixedly connected to one side of the outer wall of the guide box 2, and multiple air outlet pipes 7 are fixedly connected to the outer wall of the spiral tube 6; the air outlet component includes a trapezoidal box 4, the lower surface of which is fixedly connected to the upper surface of the guide box 2, and multiple connecting pipes 5 are fixedly connected to the upper surface of the trapezoidal box 4; the liquid outlet component includes two liquid inlet slopes 8, the outer walls of which are fixedly connected to the inner wall of the fixed plate 1, and multiple liquid outlet holes 9 are opened through the inside of the fixed plate 1;

[0026] Specifically, the fixed plate 1 serves as the basic support structure for the entire distributor, providing a stable mounting platform for other components. This ensures the distributor is firmly and securely positioned within the distillation column, preventing displacement due to vibration or airflow impact during operation. This guarantees a stable and reliable air and liquid distribution process, maintaining the continuity and stability of the distillation process. The guide box 2, fixedly connected to the upper surface of the fixed plate 1, is a crucial guiding component after air enters the distillation column. A flow ramp 3 on one side effectively guides the liquid flow in a specific direction, preventing liquid accumulation within the guide box 2 and ensuring rapid and smooth liquid discharge. This prevents backflow from affecting the normal air distribution and distillation effect, maintaining optimal gas-liquid separation. To improve the efficiency and quality of the distillation process, multiple air outlet components installed on the upper surface of the guide box 2 play a crucial role in the uniform distribution of air. Specifically, the lower surface of the trapezoidal box 4 is fixedly connected to the upper surface of the guide box 2. Its unique trapezoidal structure facilitates the concentration and dispersion of airflow, allowing the air to undergo preliminary homogenization before entering subsequent components, reducing airflow non-uniformity and laying the foundation for subsequent fine distribution. Multiple connecting pipes 5 fixedly connected to the upper surface of the trapezoidal box 4 further subdivide the air and guide it in different directions, increasing the air distribution path and enabling the air to more evenly cover the cross-section of the distillation column. This improves the sufficiency of gas-liquid contact, enhances the distillation effect, and improves the separation efficiency of gases such as oxygen and nitrogen. The auxiliary components installed on one side of the outer wall of the guide box 2 further optimize air distribution. One end of the spiral tube 6 in the auxiliary components is fixedly connected to one side of the outer wall of the guide box 2. Its spiral structure creates a spiral flow path for the air inside the tube, extending the residence time of the air and allowing for better mixing and preheating (or precooling) before entering the distillation column. This results in a more uniform temperature and pressure distribution, which is beneficial for the subsequent distillation process. Multiple outlet pipes 7 fixedly connected to the outer wall of the spiral tube 6 evenly disperse the air treated by the spiral tube 6 into the distillation column, increasing the number of air outlet points and further improving the uniformity of air distribution. This ensures more thorough gas-liquid contact and improves the overall performance and separation efficiency of the distillation column. As a result, the symmetrical liquid guide components fixedly connected to the inner wall of the fixed plate 1 are crucial for liquid discharge and liquid level control in the distillation column. The outer walls of the two liquid guide slopes 8 in the liquid guide components are fixedly connected to the inner wall of the fixed plate 1. Their inclined surfaces can guide the liquid to flow naturally to the liquid outlet 9 under the action of gravity, preventing the liquid from accumulating in the fixed plate 1 and avoiding interference with air distribution and the distillation process. This ensures the gas-liquid balance in the distillation column. The multiple liquid outlets 9 that are opened through the inside of the fixed plate 1 provide a stable discharge channel for the liquid, ensuring that the liquid can leave the distillation column in a timely and orderly manner, maintaining the normal liquid level in the distillation column, ensuring the stable operation of the distillation process, and improving distillation efficiency and product quality.

[0027] Reference Figure 1 - Figure 4A top plate 10 is provided above the connecting pipe 5. Multiple air vents 13 are perforated inside the top plate 10. An extension assembly is fixedly connected to the lower surface of the top plate 10, and a limiting assembly is installed on the outer wall of the top plate 10. The extension assembly includes an extension pipe 11, the upper surface of which is fixedly connected to the interior of the top plate 10. An extension pipe 2 12 is fixedly connected to the side of the top plate 10 away from the extension pipe 11. The outer wall of the extension pipe 11 is slidably connected to the inner wall of the connecting pipe 5, and the outer wall of the extension pipe 2 12 is slidably connected to the inner wall of the spiral pipe 6. The limiting assembly includes an extension column 1. 4. One end of the extension column 14 is fixedly connected to the outer wall of the upper top plate 10, and one end of the extension column 14 is fixedly connected to the limit plate 15. A sleeve 16 is slidably connected to the outer wall of the limit plate 15. An arc-shaped plate 17 is fixedly connected to one side of the outer wall of the sleeve 16. A spring 18 is slidably connected inside the sleeve 16. Extension tube 11 and extension tube 2 12 are both set on the inner wall of the air outlet 13. The air outlet 13 is used to install extension tube 11 and extension tube 2 12. One end of the spring 18 is fixedly connected to one side of the inner wall of the sleeve 16, and the other end of the spring 18 is fixedly connected to one side of the outer wall of the limit plate 15.

[0028] Specifically, the upper top plate 10 above the connecting pipe 5 further optimizes air distribution and controls airflow direction. Multiple air outlets 13 are perforated inside the upper top plate 10, providing precise channels for air outflow. This allows air to enter specific areas within the distillation column according to a predetermined direction and flow rate, thus enabling more precise contact and exchange with the liquid, improving the separation efficiency and accuracy of the distillation process. The extension assembly fixedly connected to the lower surface of the upper top plate 10 is crucial for enhancing the flexibility and adaptability of air distribution. The extension pipe 11 within the extension assembly is fixedly connected to the interior of the upper top plate 10, extending deep into the connecting pipe 5, effectively extending the air transmission path, allowing air to... The more uniform distribution within connecting pipe 5 reduces energy loss and turbulence during air transport, ensuring air enters the core area of ​​the distillation column in a stable state, creating favorable conditions for efficient gas-liquid exchange. The extension pipe 12, fixedly connected to the side of the upper top plate 10 away from extension pipe 11, has its outer wall slidably connected to the inner wall of the spiral tube 6. This design allows air to better adapt to the spiral structure of the spiral tube 6, maintaining a stable and uniform distribution during spiral flow. This further optimizes air mixing and preheating (or precooling) effects, improves the stability of the air entering the distillation column, and enhances the controllability and stability of the distillation process. The limiting components installed on the outer wall of the upper top plate 10 are mainly used for... The position of the top plate 10 is precisely defined and adjusted to adapt to different distillation conditions and operational requirements. One end of the extension column 14 in the limiting assembly is fixedly connected to the outer wall of the upper top plate 10, providing support and a connection base for the entire limiting structure. A limiting plate 15 is fixedly connected to one end of the extension column 14, and a sleeve 16 is slidably connected to its outer wall. An arc-shaped plate 17 is fixedly connected to one side of the outer wall of the sleeve 16, allowing the operator to easily push the sleeve 16 along the extension column 14 by applying external force to the arc-shaped plate 17, thereby causing fine-tuning of the upper top plate 10's vertical position. A spring 18 is slidably connected inside the sleeve 16, with one end fixedly connected to one side of the inner wall of the sleeve 16 and the other end fixedly connected to one side of the outer wall of the limiting plate 15. The elasticity of the spring 18 provides... A certain amount of buffering and restoring force allows the upper top plate 10 to maintain a relatively stable position after being subjected to a certain external impact or adjustment, avoiding displacement of the upper top plate 10 due to accidental vibration or interference. This ensures the stability and reliability of air distribution, guaranteeing the continuous and efficient operation of the distillation process. The air outlet 13 is used to install extension tube one 11 and extension tube two 12. This design makes extension tube one 11 and extension tube two 12 an organic whole with the upper top plate 10, ensuring that after the air is transmitted through the extension tubes, it can accurately enter the distillation column through the air outlet 13, avoiding air leakage or uneven flow, further improving the accuracy and stability of air distribution, and providing a strong guarantee for the efficient separation of distillation air.

[0029] Working principle: When the distributor is needed, the fixed plate 1 is first installed at the air inlet pipe of the equipment. At this time, the gas will be evenly distributed into the trapezoidal box 4 through the drainage slope 3 on the inner wall of the guide box 2. Then, through the diversion of the trapezoidal box 4, the gas is further distributed into the multiple connecting pipes 5. Then, through the diversion of the connecting pipes 5, the gas is evenly distributed into the equipment, thus achieving the effect of efficient gas diversion. Then, through the spiral tube 6, the gas is further diverted into the equipment, thus achieving the effect of efficient gas-liquid combination. When it is necessary to fine-tune the gas outlet position according to the equipment, the upper top plate 10 is lifted. The upper top plate 10 drives the extension tube 11 and extension tube 2 12 to slide inside the connecting tube 5 and the spiral tube 6, respectively, thus achieving the adjustment effect. At the same time, through the extension and retraction of the spring 18, the arc plate 17 is pushed against the inner wall of the equipment, thus achieving the effect of stabilizing the upper top plate 10.
