Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a self-cleaning heat exchange structure for a reaction vessel jacket. Background Technology

[0002] Reactors are widely used reaction equipment in industries such as chemical, pharmaceutical, and food processing, used to achieve processes such as mixing, heating, cooling, or chemical reactions of materials. To control the reaction temperature, reactors are typically equipped with a jacket structure. Cooling or heating media are circulated through the jacket to regulate the temperature of the reactor body. However, during long-term operation, scaling can easily occur inside the jacket due to residual media and impurities, affecting heat exchange efficiency and even causing equipment instability. Therefore, regular cleaning and maintenance are necessary.

[0003] To address this issue, various self-cleaning heat exchange structures have been developed in existing technologies, such as high-pressure flushing and mechanical scraping, to reduce manual intervention and improve the continuity and reliability of equipment operation. While these methods improve the cleanliness of the jacket interior to some extent, problems such as cleaning dead zones, high energy consumption, and complex structures still exist. Especially in jacket structures, the confined space and complex flow channels on the inner wall of the shell and the surface of the spiral baffles make these areas prone to dirt accumulation. Traditional cleaning methods struggle to effectively cover these areas, resulting in unsatisfactory cleaning effects that affect heat exchange efficiency and equipment lifespan. Although some devices have introduced ultrasonic cleaning technology to enhance cleaning capabilities, problems such as limited cleaning range and uneven energy distribution still exist in practical applications, failing to fully meet the actual need for efficient and thorough removal of adhering dirt.

[0004] Therefore, it is necessary to design a self-cleaning heat exchange structure for the reactor jacket to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of traditional cleaning methods, which are difficult to effectively cover these areas, especially in jacketed structures, resulting in unsatisfactory cleaning effects and affecting heat exchange efficiency and equipment lifespan, this utility model provides a self-cleaning heat exchange structure for reactor jackets.

[0006] Technical solution: A self-cleaning heat exchange structure for a reactor jacket includes a shell, a reactor body, an inlet pipe, a sleeve, a conical baffle, a spiral baffle, an outlet pipe, and a cleaning component. The shell is located around the reactor body, forming a sealed jacket space between them. The inlet pipe is connected to and communicates with the right side of the shell. The sleeve is fixedly connected to the bottom of the shell. A conical baffle is provided between the inner bottom of the shell and the reactor body. The conical baffle has a structure that is high in the middle and low at the edges. A spiral baffle is provided between the inside of the shell and the reactor body. The bottom of the shell is connected to and communicates with the top periphery of the conical baffle through an outlet pipe. An installation hole is provided on the top periphery of the shell. A cleaning component is provided on the front side and inside of the shell.

[0007] Furthermore, the cleaning assembly includes an ultrasonic generator and an ultrasonic transducer. The ultrasonic generator is mounted on the front side of the housing, and its left end extends through the front side of the housing and is connected to the ultrasonic transducer. The ultrasonic transducer extends in a spiral shape to the bottom of the housing and is located above the spiral partition.

[0008] Furthermore, it also includes a sealing ring, which is provided on the inner side of the top of the housing.

[0009] Furthermore, it also includes a heat-conducting plate, which is fixedly connected to the inner side of the upper part of the shell and is located between the reactor body and the spiral partition.

[0010] Furthermore, it also includes a booster pipe and a pressure regulating valve. The right side of the inlet pipe is connected to a booster pipe that is large at both ends and small in the middle. A pressure regulating valve is installed in the recessed part of the booster pipe.

[0011] Furthermore, it also includes a gas supply pipe, a pressure relief valve, a diverter pipe, and a check valve. The upper left side of the housing is connected to and communicates with a downward-extending gas supply pipe. A pressure relief valve is provided on the upper part of the gas supply pipe. The gas supply pipe extends to the bottom of the housing and is connected to and communicates with multiple diverter pipes. Each diverter pipe passes through the top of the conical partition and is flush with the inclined surface of the conical partition. A check valve is installed at the lower part of each diverter pipe.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention achieves efficient ultrasonic cleaning of the inner wall of the shell and the surface of the spiral partition by setting an ultrasonic generator and a spiral ultrasonic transducer connected to the front side of the shell, effectively preventing the deposition of impurities, reducing the frequency of manual cleaning, and realizing the self-cleaning function of the jacket structure.

[0013] 2. This utility model achieves the effect of enhancing the flow rate of the heat exchange medium and improving the heat exchange efficiency by setting a spiral baffle inside the shell and connecting a pressure boosting pipe with large ends and a small middle section and a pressure regulating valve on the liquid inlet pipe. At the same time, it achieves precise control of flow rate and pressure through the Venturi effect, thereby improving the stability and energy efficiency of the system.

[0014] 3. This utility model uses a gas circulation structure composed of a gas supply pipe, a pressure relief valve, a diversion pipe, and a one-way valve to guide the hot gas generated during the heat exchange process to the bottom of the shell and spray it out through the diversion pipe flush with the inclined surface of the conical baffle. This achieves the effect of preventing the top of the conical baffle from thickening and becoming difficult to clean due to long-term operation. At the same time, the one-way valve effectively prevents the backflow of gas or liquid, improving the overall reliability and self-maintenance capability of the system. Attached Figure Description

[0022] Example: A self-cleaning heat exchange structure for a reactor jacket, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the reactor includes a shell 1, a reactor body 101, an inlet pipe 2, a sleeve 3, a conical baffle 4, a spiral baffle 5, an outlet pipe 6, and a cleaning assembly. The shell 1 is located around the reactor body 101, forming a sealed jacket space between them. The inlet pipe 2 is connected to and communicates with the right side of the shell 1. The sleeve 3 is integrally formed at the bottom of the shell 1. A conical baffle 4 is provided between the inner bottom of the shell 1 and the reactor body 101. The conical baffle 4 has a structure that is high in the middle and low at the edges. The interior of the shell 1 and the reactor body... A spiral partition 5 is provided between 101. The bottom of the housing 1 is connected to the outer periphery of the top of the conical partition 4 and is connected to the liquid outlet pipe 6. An installation hole 7 is provided on the outer periphery of the top of the housing 1. A cleaning assembly is provided on the front side and inside of the housing 1. The cleaning assembly includes an ultrasonic generator 12 and an ultrasonic transducer 13. An ultrasonic generator 12 is installed on the front side of the housing 1. Its left end passes through the front side of the housing 1 and is connected to the ultrasonic transducer 13. The ultrasonic transducer 13 extends spirally to the bottom of the housing 1 and is located above the spiral partition 5.

[0023] like Figures 1-6 As shown, it also includes a sealing ring 8, a heat-conducting plate 9, a pressure boosting pipe 10, and a pressure regulating valve 11. The sealing ring 8 is provided on the inner side of the top of the shell 1. The heat-conducting plate 9 is connected to the inner side of the upper part of the shell 1 by bolts. The heat-conducting plate 9 is located between the reactor body 101 and the spiral partition 5. The right side of the liquid inlet pipe 2 is connected to and communicates with a pressure boosting pipe 10 that is large at both ends and small in the middle. A pressure regulating valve 11 is installed in the recessed part of the middle of the pressure boosting pipe 10 to increase the liquid flow rate.

[0024] like Figure 1 and Figure 7 As shown, it also includes a gas supply pipe 14, a pressure relief valve 15, a diverter pipe 16, and a one-way valve 17. The upper left side of the housing 1 is connected to and communicates with the downward-extending gas supply pipe 14. The gas supply pipe 14 is equipped with a pressure relief valve 15 at its upper part. The gas supply pipe 14 extends to the bottom of the housing 1 and is connected to and communicates with the bottom of the housing 1 through multiple diverter pipes 16. Each diverter pipe 16 passes through the top of the conical partition 4 and is flush with the inclined surface of the conical partition 4. A one-way valve 17 is installed at the lower part of each diverter pipe 16.

[0025] Operators can apply the corresponding technical solutions in this device to the heat exchange and self-cleaning technology of the reactor jacket according to specific circumstances. When this device is needed to assist in the liquid circulation and heat exchange operation within the reactor jacket, firstly, the cooling or heating medium is injected into the sealed jacket space between the shell 1 and the reactor body 101 through the inlet pipe 2, flowing within the shell 1 to achieve heat exchange treatment of the reactor body 101; simultaneously, the spiral baffle 5 installed inside the shell 1 guides the fluid in a spiral flow path, prolonging the fluid residence time and improving heat exchange efficiency. To further enhance the flow rate and heat exchange effect, the medium in the inlet pipe 2 can also be pressurized through the pressure booster pipe 10, utilizing its structure of being large at both ends and small in the middle to create a Venturi effect. A pressure regulating valve 11 is installed at the concave part in the middle of the pressure booster pipe 10 to control the flow rate and pressure, ensuring stable system operation.

[0026] During the heat exchange process, the heat-conducting plate 9 installed on the inner side of the upper part of the shell 1 can further enhance the heat transfer efficiency and make the temperature distribution more uniform; while the sealing ring 8 on the inner side of the top of the shell 1 effectively prevents media leakage and ensures the sealing and safety of the system. In order to achieve the self-cleaning function, an ultrasonic generator 12 is provided on the front side of the shell 1, and the ultrasonic transducer 13 connected to its left end extends into the interior of the shell 1 in a spiral shape and is located above the spiral partition 5. During the heat exchange process, ultrasonic waves are continuously emitted to generate a cavitation effect, which destroys the impurities deposited on the inner wall of the shell 1 and the surface of the spiral partition 5, thereby achieving the purpose of automatic cleaning and reducing the frequency of manual maintenance.

[0027] In addition, a certain amount of hot air is generated during the high-temperature heat exchange process. This hot air will naturally rise and accumulate in the upper part of the shell 1. To address this, a downward-extending gas supply pipe 14 is provided on the upper left side of the shell 1 to guide the hot air to the bottom area of ​​the shell 1. A pressure relief valve 15 is provided on the upper part of the gas supply pipe 14 to regulate the pressure inside the system. After the hot air is delivered to the bottom of the shell 1 through the gas supply pipe 14, it is sprayed outward through multiple diversion pipes 16 that penetrate the top of the conical baffle 4. The spray direction is flush with the inclined surface of the conical baffle 4, which can effectively impact the top area of ​​the conical baffle 4 and prevent dirt from accumulating and thickening due to long-term operation, making it difficult to clean. A one-way valve 17 is installed at the lower part of each diversion pipe 16 to allow gas to flow only from top to bottom, preventing liquid or gas inside the shell 1 from flowing back into the gas supply pipe 14, thereby further ensuring the stability and cleaning effect of the system.

[0028] In summary, this self-cleaning heat exchange structure for reactor jackets, through reasonable flow channel design, ultrasonic cleaning technology, and the integration of auxiliary control components, not only improves heat exchange efficiency but also achieves efficient self-cleaning inside the jacket. It has advantages such as reasonable structure, convenient operation, and low maintenance cost, and is suitable for application scenarios in industries such as chemical and pharmaceutical where the cleanliness and heat exchange performance of reactor jackets are highly demanding.
