[0002] The booster tower for air separation is a specially designed distillation tower used to efficiently separate nitrogen, oxygen and other components in the air. This booster tower combines distillation technology with special tray or filler design to improve the separation efficiency of air components. In the air separation process, the booster tower uses the difference in boiling points of different components in the tower to achieve separation. The air first enters the bottom of the tower. Through heating and sublimation, the vapors of different components rise in the tower and contact and exchange with the descending condensed liquid. By controlling the temperature and pressure conditions and using the special structure of the tray or filler, efficient component separation can be achieved.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model embodiment provides a tower with efficiency enhancement for air separation, such as Figure 1-4 As shown, the efficiency-enhancing tower for air separation comprises: a tower body 1 with an air separation function, wherein the tower body 1 is provided with an exhaust port 2; a connecting pipe 3 fixedly mounted on the exhaust port 2, wherein the connecting pipe 3 is provided with a flow groove 4 for flowing liquid; a water tank 5 fixedly mounted on the tower body 1 for storing water, wherein a delivery pipe 17 is fixedly mounted on the top of the water tank 5, wherein one end of the delivery pipe 17 is fixedly connected to the connecting pipe 3, and the delivery pipe 17 is communicated with the flow groove 4; a conveying mechanism mounted on the water tank 5 for conveying water; and a stirring mechanism mounted on the water tank 5 for stirring water.

[0024] It should be noted that since the gas usually needs to go through multiple processing steps to achieve the required purity or meet specific process requirements, with a gas enhancement tower as one of the processing units, after processing the gas, the gas is generally transmitted to the next equipment through a pipeline for processing. The transmitted gas will contain more heat, which usually cannot be utilized, thereby wasting a lot of thermal energy.

[0025] In the scheme, firstly, the tower body 1 with an enhancement has an air separation function, and through its specially designed tower plates and fillers, it can realize efficient separation of different components in the air. After the air is heated and sublimated, the vapors of different components rise in the tower, and contact and exchange with the descending condensed liquid, thereby achieving the purpose of separation. The tower body 1 with an enhancement belongs to the existing mature technology and will not be described in detail here. Secondly, the tower body 1 with an enhancement is provided with an exhaust port 2, and a connecting pipe 3 is fixedly installed. The connecting pipe 3 is used to transfer the treated gas to the next treatment equipment. The innovation here is that a flow groove 4 is opened on the connecting pipe 3 for the flow of liquid. This design enables the gas to exchange heat with the liquid in the flow groove 4 during the transmission process, thereby realizing heat recovery. Furthermore, a water tank 5 is also fixedly installed on the tower body 1 with an enhancement for storing water. The top of the water tank 5 is fixedly installed There is a delivery pipe 17, one end of which is fixedly connected to the connecting pipe 3 and is connected to the circulation groove 4, so that the water in the circulation groove 4 can flow into the water tank 5. In order to transport the water in the water tank 5 to the circulation groove 4, a delivery mechanism is also installed. This delivery mechanism can ensure that the water in the water tank 5 can flow smoothly into the circulation groove 4. In addition, in order to make the water temperature in the water tank 5 evenly dispersed, the water tank 5 is also equipped with a stirring mechanism. This stirring mechanism can quickly disperse the heat into the water in the water tank 5 by stirring the water. Through the design of the utility model, after the efficiency-enhancing tower body 1 has treated the gas, it can not only efficiently transmit the gas to the next treatment equipment, but also use the circulation groove 4 on the connecting pipe 3 and the water in the water tank 5 for heat exchange to recover the heat in the gas. In this way, not only the energy utilization efficiency is improved, but also the energy waste is reduced, achieving the dual goals of environmental protection and energy saving.

[0026] In a further preferred embodiment of the utility model, the conveying mechanism includes: a water pump 6 fixedly installed on the top of the water tank 5; a water suction pipe 7 fixedly installed on the water suction end of the water pump 6, one end of the water suction pipe 7 extends to the interior of the water tank 5; a discharge pipe 8 fixedly installed on the discharge end of the water pump 6, one end of the discharge pipe 8 is fixedly connected to the connecting pipe 3, and the discharge pipe 8 is connected to the circulation groove 4.

[0027] In this embodiment, the conveying mechanism is mainly composed of a water pump 6, a pumping pipe 7 and a discharge pipe 8. The water pump 6 is fixedly installed on the top of the water tank 5. As the power source of the entire conveying mechanism, it is responsible for pumping water from the water tank 5 and conveying it to the circulation groove 4. One end of the pumping pipe 7 is fixedly connected to the pumping end of the water pump 6, and the other end extends to the inside of the water tank 5 to ensure that the water pump 6 can smoothly pump water from the water tank 5. One end of the discharge pipe 8 is fixedly connected to the drainage end of the water pump 6, and the other end is fixedly connected to the connecting pipe 3 and is connected to the circulation groove 4. In this way, when the water pump 6 is working, water will be sucked in through the pumping pipe 7, and then flow into the circulation groove 4 of the connecting pipe 3 through the discharge pipe 8, absorbing the heat of the gas in the connecting pipe 3. The water after absorbing heat will enter the water tank 5 from the conveying pipe 17, realizing heat recovery and utilization.

[0028] In a further preferred embodiment of the utility model, the stirring mechanism includes: a bracket 9 welded to the inner wall at the top of the water tank 5, a rotating shaft 10 is rotatably mounted on the bracket 9, and the top end of the rotating shaft 10 extends to the inside of the conveying pipe 17; an impeller 11 fixedly mounted on the top end of the rotating shaft 10; and a plurality of stirring rods 12 welded on the rotating shaft 10 for stirring water.

[0029] In this embodiment, the stirring mechanism is used to stir the water in the water tank 5. When the water in the circulation groove 4 enters the water tank 5 from the delivery pipe 17, the water flow will drive the impeller 11 to rotate, and the impeller 11 will drive the rotating shaft 10 to rotate on the bracket 9. The rotating shaft 10 will drive multiple stirring rods 12 to rotate, stirring the water in the water tank 5 so that the heat of the water is evenly dispersed.

[0030] In a further preferred embodiment of the present invention, a first liquid level sensor 13 and a second liquid level sensor 14 are fixedly mounted on an inner wall of one side of the water tank 5 , and the second liquid level sensor 14 is located below the first liquid level sensor 13 .

The arrangement of these two liquid level sensors enables the liquid level in the water tank 5 to be accurately monitored and controlled. When the water level in the water tank rises to the position of the first liquid level sensor 13, the sensor will send a signal to remind the system or operator to pay attention to the change in the water level to prevent water overflow or excessive water. Similarly, when the water level drops to the position of the second liquid level sensor 14, the sensor will also send a signal to indicate the need for timely water replenishment to ensure the normal operation of the equipment and the efficiency of heat recovery and utilization.

[0032] In a further preferred embodiment of the present invention, a water adding pipe 15 for adding water is fixedly installed on one side of the water tank 5 , and a first solenoid valve is provided on the water adding pipe 15 .

When water replenishment is needed, the switching state of the first solenoid valve 16 can be controlled to achieve precise control of the amount of water added, thereby preventing problems caused by adding too much or too little water.

[0034] In a further preferred embodiment of the present invention, a water outlet pipe 16 for discharging water is fixedly installed at the bottom of the water tank 5 , and a second solenoid valve is provided on the water outlet pipe 16 .

[0035] In this embodiment, the setting of the water outlet pipe 18 allows the water in the water tank 5 to be easily discharged when needed, and the water can be used for washing hands and mopping the floor, etc. The addition of the second solenoid valve can prevent water from flowing out of the water outlet pipe 18, or it can allow water to flow out of the water outlet pipe 18.

[0036] In a further preferred embodiment of the utility model, a positioning block is fixedly installed on one side of the efficiency-enhancing tower body 1 , and one side of the positioning block is fixedly connected to the connecting pipe 3 .

[0037] In this embodiment, the positioning block plays a key role in fixing and supporting. By fixedly connecting the positioning block to the efficiency-enhancing tower body 1, the stability and reliability of the delivery pipe 3 can be ensured.

[0038] In a further preferred embodiment of the present invention, the bracket 9 is configured to be L-shaped, and the impeller 11, the rotating shaft 10 and the plurality of stirring rods 12 are all made of stainless steel.

[0039] In this embodiment, the impeller 11, the rotating shaft 10 and the multiple stirring rods 12 are all made of stainless steel. Stainless steel has excellent corrosion resistance and strength, which can ensure that the stirring mechanism can maintain good performance during long-term operation and in complex environments. This material selection not only extends the service life of the stirring mechanism, but also improves the reliability of the entire system.
