Description

Technical Field

[0001] This application relates to the field of condensation cycle technology, and particularly to a circulating condensation device. Background Art

[0002] In existing circulating condensation systems, temperature control mainly relies on an electric control compressor to refrigerate the refrigerant to achieve low-temperature circulating condensation. The core of this system lies in maintaining a low temperature state during the condensation process through compression refrigeration. However, this traditional method has several significant challenges and deficiencies.

[0003] Firstly, the refrigeration of the electric control compressor used in the existing system relies on refrigerants such as Freon. Although Freon performs excellently in terms of refrigeration effect, the environmental pollution problems it causes cannot be ignored. The use of Freon will lead to the destruction of the ozone layer and have a negative impact on global climate change.

[0004] Secondly, in the existing system, the cooling of the reaction kettle and the recovery of distillates usually require two independent systems. One system is responsible for circulating the coolant to the reaction kettle body to maintain the required low temperature state; the other system is used for recovering distillates. This separated system not only makes the operation complicated but also faces difficulties in maintenance and cleaning. Due to the independent operation of the two systems, the technological process becomes more cumbersome. The operator needs to coordinate and manage the operation of multiple systems, which increases the complexity of the operation and the risk of errors.

[0005] Therefore, there is an urgent need to develop a more environmentally friendly, efficient, and at the same time, a circulating condensation system that can simplify the operation and maintenance process. Summary of the Utility Model

[0006] In order to develop a more environmentally friendly, efficient, and at the same time, a circulating condensation system that can simplify the operation and maintenance process, this application provides a circulating condensation device.

[0007] The circulating condensation device provided by this application adopts the following technical solutions:

[0008] A circulating condensation device for the circulating condensation work of a device to be cooled, comprising:

[0009] A condensing pipe, connected and communicated with the device to be cooled;

[0010] A refrigeration unit, connected to the condensing pipe for providing coolant for the condensing pipe;

[0011] A first valve body, connecting the condensing pipe and the device to be cooled;

[0012] A second valve body, connected to the condensing pipe and externally connected with a storage container.

[0013] By adopting the above technical solution, the design of the device simplifies the operation of the cooling system. The flow and recovery of the refrigerant are controlled by two valve bodies, reducing the complexity and maintenance difficulty of the system. The coolant in the condensation pipe effectively cools the high-temperature gas generated by the device to be cooled and condenses it into a liquid, thus achieving efficient heat exchange and cooling. By opening and closing the first valve body, the condensed liquid can be returned to the device to be cooled to provide a continuous cooling effect to maintain the required low-temperature state. By means of the second valve body, when a predetermined condition is reached, the condensed liquid can be collected into a storage container to meet different operation requirements. During this process, by recycling and collecting the condensed liquid, the energy utilization efficiency of the system can be improved, waste can be reduced, and the impact on the environment can be minimized.

[0015] By adopting the above technical solution, during operation, the high-temperature gas in the device to be cooled enters the condensation pipe through the drainage hole on the condensation pipe. The refrigeration unit conveys low-temperature coolant to the condensation coil. The high-temperature gas entering the condensation pipe exchanges heat with the coolant in the condensation coil, reducing the gas temperature and finally condensing the gas into a liquid. By setting the condensation coil to be connected to the refrigeration unit, the condensation efficiency and cooling capacity are improved. The arrangement of the condensation coil can increase the contact area between the coolant and the gas, thereby improving the heat exchange efficiency, enabling the gas to be cooled and condensed into a liquid more quickly, ensuring the high efficiency of the entire condensation process, improving the stability and operation efficiency of the system, and contributing to energy conservation and environmental protection.

[0016] In a specific feasible embodiment, a drainage pipe is further arranged inside the condensation pipe and is communicated with the drainage hole.

The spherical structure is provided with a through hole communicated with the drainage pipe, and the spherical structure is used to prevent the condensed liquid from dripping back into the device to be cooled.

[0019] By adopting the above technical solution, the design of the spherical structure provides a buffer area, which helps the fluid to flow smoothly to the bottom of the condenser tube. The through-hole of the spherical structure allows the gas to pass through while preventing the liquid from dripping back to the device to be cooled. The liquid reflux is effectively avoided through its spherical design, and the through-hole design of the spherical structure can ensure the separation of gas and liquid, thereby optimizing the condensation process and enhancing the stability and performance of the system.

[0020] In a specific feasible implementation, the diameter of the spherical structure is larger than the diameter of the drainage tube, and the through-hole is arranged close to the drainage tube.

[0021] By adopting the above technical solution, the design that the diameter of the spherical structure is larger than the diameter of the drainage tube and the through-hole is close to the drainage tube can prevent the liquid reflux, optimize the condensation process, and enhance the stability and efficiency of the entire cooling system by providing a sufficient liquid buffer area and an effective liquid blocking mechanism.

[0022] In a specific feasible implementation, a plurality of through-holes are provided, and the plurality of through-holes are arranged along the circumferential direction of the spherical structure.

[0023] By adopting the above technical solution, the plurality of through-holes provide a plurality of gas discharge paths, thereby improving the uniformity and efficiency of gas flow, ensuring the uniform discharge of gas, and effectively blocking the liquid reflux, thus improving the efficiency and stability of the cooling system.

[0024] In a specific feasible implementation, the condensation coil is wound around the height direction of the condenser tube.

[0025] By adopting the above technical solution, the winding design increases the contact area between the coolant and the gas, improves the heat exchange efficiency; and the condensation coil wound around the height direction of the condenser tube can achieve a more uniform cooling effect, reduce the temperature difference between the gas and the liquid, and improve the condensation efficiency.

[0026] In a specific feasible implementation, the refrigeration unit includes a semiconductor refrigeration module, a cold liquid tank and a pump body. The semiconductor refrigeration module is connected to the cold liquid tank, and the pump body connects the cold liquid tank and the condenser tube.

[0027] By adopting the above technical solution, during operation, the semiconductor refrigeration module is driven by an electric current to cool the liquid in the cold liquid tank to form a coolant. The cooled liquid is pumped out of the cold liquid tank by a pump body and transported through the pump body into the condensation tube. The coolant exchanges heat with the gas or other medium to be cooled in the condensation tube, taking away its heat, cooling and condensing the gas. After the heat exchange is completed, the coolant flows back from the condensation tube to the cold liquid tank, and the pump body re-pumps the liquid to continue the cycle cooling process; through the coordinated operation of the above components, an efficient cooling system is formed. The semiconductor refrigeration module provides cooling control and can efficiently reduce the temperature of the coolant. The pump body ensures the stable circulation of the coolant in the system, maintaining the continuity and efficiency of the cooling process, thereby achieving efficient heat exchange and stable cooling effect.

[0028] In a specific feasible implementation, the cold liquid tank is provided with a temperature probe for detecting the liquid temperature in the cold liquid tank.

[0037] The following Figures 1-3 further elaborates on this application in detail with reference to the attached drawings.

[0038] Referring to Figure 1 and Figure 2 In the embodiments of this application, a circulating condensation device is disclosed, which is used for the circulating condensation work of the device to be cooled. In this embodiment, the device to be cooled is a reaction kettle. In this embodiment, the circulating condensation device includes but is not limited to the industrial process for the multi-purpose control of condensation applied to the reaction kettle, and the automatic control of the condensation reflux and solvent solute recovery of the reaction kettle in chemical engineering;

[0039] The circulating condensation device includes:

[0040] The condenser tube 1, the condenser tube 1 is connected and communicated with the reaction kettle 6. In this embodiment, there is a hole on the reaction kettle 6 that is communicated with the condenser tube 1, and the high-temperature gas in the reaction kettle 6 rises and flows into the condenser tube 1 for cooling and condensing into a liquid;

[0041] The refrigeration unit 2, the refrigeration unit 2 is connected to the condenser tube 1 and is used to provide cooling liquid for the condenser tube 1;

[0042] The first valve body 3, the first valve body 3 connects the condenser tube 1 and the reaction kettle 6. In this embodiment, the condensed liquid falls into the condenser tube 1 and, when needed, flows back into the reaction kettle 6 through the first valve body 3 to provide a continuous cooling effect to maintain the required low-temperature state in the reaction kettle 6;

[0043] The second valve body 4, one end of the second valve body 4 is connected to the condenser tube 1, and the other end of the second valve body 4 is externally connected to a storage container 7, which is used to separately collect the fractions of the condensed liquid at different temperatures. When the predetermined conditions are reached, the condensed liquid can be collected into the storage container 7 to adapt to different operation requirements and realize the reception of distillates (solvent recovery, distillation products);

[0044] It also includes a temperature sensor 5 for detecting the gas temperature inside the reaction kettle 6. Before operation, the temperature sensor 5 is inserted into the reaction kettle 6 through a hole on the reaction kettle 6. The temperature sensor 5 detects the gas temperature inside the reaction kettle 6 in real time to control the cooling process, realize the collection of fractions under different temperature conditions. Through the feedback of real-time temperature data, the system can optimize the cooling conditions, improve the separation efficiency, and ensure the accurate collection of each fraction.

[0045] During operation, the refrigeration unit 2 delivers coolant to the condenser tube 1. The high-temperature gas inside the reaction kettle 6 enters the condenser tube 1 and condenses into a liquid through the cooling of the coolant inside the condenser tube 1. When it is necessary to circulate and reflux the condensed liquid, the first valve body 3 is opened, and the liquid inside the condenser tube 1 flows back into the reaction kettle 6 through the first valve body 3. When it is necessary to meet certain collection conditions for the condensed liquid, the second valve body 4 is opened, and the liquid inside the condenser tube 1 flows out through the second valve body 4 and is collected and stored in the storage container 7.

[0046] The flow and recovery of the condensed liquid after condensation are realized through the two valve bodies, which simplifies the operation of the cooling system, can reduce the complexity and maintenance difficulty of the system. The coolant in the condenser tube 1 effectively cools and condenses the high-temperature gas generated by the reaction kettle 6 into a liquid, thus realizing efficient heat exchange and cooling; and can improve the energy utilization efficiency of the system, reduce waste, and reduce the impact on the environment.

[0047] Refer to Figure 2 and Figure 3 As shown in [relevant figure numbers], a drainage hole 11 is provided at the bottom of the condenser tube 1, and the drainage hole 11 is communicated with the reaction kettle 6. A condensation coil 12 is provided inside the condenser tube 1, and the condensation coil 12 is connected to the refrigeration unit 2.

[0048] The condensation coil 12 is wound around the condenser tube 1 along the height direction. In this embodiment, the condensation coil 12 is wound from the top to the bottom side of the condenser tube 1. In this embodiment, the winding height of the condensation coil 12 is greater than or equal to half of the height of the condenser tube 1. The winding design can increase the contact area between the coolant and the gas, improve the heat exchange efficiency; and the condensation coil 12 wound along the height direction of the condenser tube 1 can achieve a more uniform cooling effect, reduce the temperature difference between the gas and the liquid, and improve the condensation efficiency.

[0049] A drainage tube 13 is also provided inside the condenser tube 1. The drainage tube 13 extends to one side of the condenser tube 1. The drainage tube 13 is correspondingly arranged and communicated with the drainage hole 11. By designing the drainage tube 13, the flow direction of the gas can be ensured and the flow speed can be increased, which helps to improve the efficient heat exchange between the gas and the condensation coil 12, thereby improving the condensation efficiency and system stability, and making the cooling process more efficient and reliable.

[0050] The drain pipe 13 extends towards the side of the condensation coil 12 and is provided with a spherical structure 14. The spherical structure 14 is provided with a through hole 15 communicating with the drain pipe 13, and the through hole 15 is arranged close to the drain pipe 13 and is located on one side of the bottom of the spherical structure 14. The diameter of the spherical structure 14 is larger than the diameter of the drain pipe 13. The spherical structure 14 is used to prevent the condensed liquid from dripping back into the reaction kettle 6; the design of the spherical structure 14 provides a buffer area, which helps the liquid to flow smoothly to the bottom of the condenser 1. The through hole 15 of the spherical structure 14 allows the gas to pass through, while preventing the liquid from dripping back into the device to be cooled. The spherical design effectively avoids liquid backflow. The design of the through hole 15 of the spherical structure 14 can ensure the separation of gas and liquid, thereby optimizing the condensation process and enhancing the stability and performance of the system;

[0051] The through holes 15 are provided in plurality, and the plurality of through holes 15 are arranged along the circumferential direction of the spherical structure 14; in actual work, the plurality of through holes 15 provide multiple gas discharge paths, thereby improving the uniformity and efficiency of gas flow, ensuring the uniform discharge of gas, and effectively blocking liquid backflow, thereby improving the efficiency and stability of the cooling system;

[0052] During operation, the high-temperature gas in the reaction kettle 6 enters the condenser 1 through the drain hole 11 on the condenser 1, flows towards the side of the condensation coil 12 under the guidance of the drain pipe 13, flows out through the through hole 15 of the spherical structure 14 and flows towards the condensation coil 12. During this process, the refrigeration unit 2 delivers low-temperature cooling liquid to the condensation coil 12. The high-temperature gas entering the condenser 1 exchanges heat with the cooling liquid in the condensation coil 12, reducing the gas temperature and finally condensing the gas into a liquid; the condensed liquid falls downward and gathers at the bottom of the condenser 1. During this process, when the liquid falls, the spherical structure 14 provides a buffer area, which helps the liquid to flow smoothly to the bottom of the condenser 1 and can prevent the liquid from flowing back into the drain pipe 13.

[0053] Refer to Figure 1 and Figure 2 As shown in, the refrigeration unit 2 includes a semiconductor refrigeration module 21, a cold liquid tank 22 and a pump body 23. The semiconductor refrigeration module 21 is connected to the cold liquid tank 22, and the pump body 23 is connected to the cold liquid tank 22 and the condenser 1. In this embodiment, one end of the pump body 23 is connected to the cold liquid tank 22, and the other end is connected to the condensation coil 12 of the condenser 1 to form a circulating liquid supply;

[0054] Through the cooperation of the semiconductor refrigeration module 21, the cold liquid tank 22 and the pump body 23, an efficient cooling system is formed. The semiconductor refrigeration module 21 provides cooling control and can efficiently reduce the temperature of the coolant. The pump body 23 ensures that the coolant circulates stably in the system, maintaining the continuity and efficiency of the cooling process, thereby achieving efficient heat exchange and stable cooling effect. In addition, the semiconductor refrigeration breaks through the refrigeration and precise control of traditional compressors, overcomes the traditional high dependence on refrigerants (Freon), greatly reduces equipment space, and improves the reaction temperature control accuracy.

[0055] The cold liquid tank 22 is provided with a temperature probe 24 for detecting the temperature of the liquid in the cold liquid tank 22. By real-time monitoring the temperature in the liquid tank, the system can automatically adjust the cooling of the cold liquid tank 22 by the semiconductor refrigeration module 21 to maintain efficient cooling performance. Accurate temperature control can reduce failures or performance degradation caused by abnormal liquid temperature, ensure the stability and efficiency of the cooling system, and enhance the reliability and equipment life of the overall system.

[0056] When working, the semiconductor refrigeration module 21 is driven by electric current to cool the liquid in the cold liquid tank 22 to form a coolant. The cooled liquid is pumped out of the cold liquid tank 22 by the pump body 23 and transported to the condenser 1 through the pump body 23. The coolant exchanges heat with the gas or other medium to be cooled in the condenser 1, takes away its heat, cools the gas and condenses it. After the heat exchange is completed, the coolant flows back from the condenser 1 to the cold liquid tank 22, and the pump body 23 re-extracts the liquid to continue the cycle cooling process. During this process, the temperature probe 24 in the cold liquid tank 22 detects the liquid temperature in the cold liquid tank 22 in real time, thereby automatically adjusting the cooling of the cold liquid tank 22 by the semiconductor refrigeration module 21, so that the condensing coil 12 can maintain efficient cooling performance.

[0057] The implementation principle of a circulating condensing device in the embodiment of the present application is as follows: before operation, the circulating condensing device is installed on the reactor 6, so that the drainage hole 11 on the condensing tube 1 is connected with the hole on the reactor 6, and the temperature sensor 5 enters the reactor 6 through the hole on the reactor 6, and the temperature sensor 5 detects the gas temperature in the reactor 6 in real time;

[0058] During operation, the high-temperature gas in the reaction kettle 6 enters the condenser tube 1 through the drainage holes 11 on the condenser tube 1, flows towards the side of the condenser coil 12 under the guidance of the drainage pipe 13, flows out through the through hole 15 of the spherical structure 14 and flows towards the condenser coil 12; during this process, the semiconductor refrigeration module 21 is driven by an electric current to cool the liquid in the coolant tank 22 to form a coolant. The cooled liquid is pumped out of the coolant tank 22 by the pump body 23 and transported through the pump body 23 to the condenser coil 12 in the condenser tube 1. The coolant exchanges heat with the gas or other medium to be cooled in the condenser tube 1, takes away its heat, cools and condenses the gas. The condensed liquid falls downward and collects at the bottom of the condenser tube 1. During this process, when the liquid falls, the spherical structure 14 provides a buffer area, which helps the liquid to flow smoothly to the bottom of the condenser tube 1 and can prevent the liquid from flowing back into the drainage pipe 13;

[0059] When it is necessary to circulate and reflux the liquid formed by condensation, open the first valve body 3, and the liquid in the condenser tube 1 flows back into the reaction kettle 6 through the first valve body 3; when it is necessary to meet certain collection conditions for the liquid formed by condensation, open the second valve body 4, and the liquid in the condenser tube 1 flows out through the second valve body 4 and is collected and stored in the storage container 7;

[0060] This application utilizes the collaborative design of the refrigeration unit 2 of the semiconductor, the condenser tube 1 and the double valve body. The system efficiently cools and condenses the high-temperature gas into a liquid, improving the heat exchange efficiency. The double valve body design simplifies the flow and recovery operations of the condensate, improves the integrated design of the system, and reduces the system complexity and maintenance difficulty; the semiconductor refrigeration technology overcomes the dependence on traditional refrigerants, improves the accuracy of reaction temperature control, and reduces the equipment footprint, making the system more compact, optimizing the overall design, and also being able to reduce energy waste, reduce the impact on the environment, and improve the energy utilization efficiency through efficient cooling and circulating flow.

[0061] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
