Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a high-pressure reaction vessel with dual-disc temperature control. Background Technology

[0002] High-pressure reactors are suitable for chemical reactions in high-temperature, high-pressure, high-vacuum, flammable, explosive, and highly toxic media. They can be designed according to different user process requirements and are available in various materials. Features such as pressurized feeding, bottom discharge, and pressure transmission can be designed. They are mainly used in petrochemical, chemical, pharmaceutical, polymer synthesis, and metallurgical fields. However, some high-pressure reactors utilize waste steam for material insulation, heating, and evaporation, which is costly, energy-intensive, and may cause environmental pollution. Furthermore, they are more suitable for material reactions requiring only heating and are not suitable for cooling conditions in high-pressure reactors. Therefore, the patent announcement number CN222305709U discloses "A High-Pressure Reactor with Dual-Coil High-Efficiency Temperature Control". The solution includes a reactor with a solid feed inlet, a liquid feed inlet, a motor inlet, an inspection inlet, and a condensation inlet at its top. The reactor interior includes an upper coil, a lower coil, and multiple stirring paddles. The stirring paddles are located in the hollow space between the upper and lower coils. The upper and lower coils are symmetrically arranged vertically within the reactor, with the same circumferential diameter from top to bottom. Gaps are provided between the upper and lower coils and the inner wall of the reactor, allowing for good axial and radial flow of the material inside the reactor and creating turbulence near the coils, effectively improving the uniformity of material heating.

[0003] However, conventional rinsing is ineffective for firmly attached scale, polymers, or catalyst particles, often requiring prolonged soaking and manual scrubbing, which prolongs equipment downtime and results in low cleaning efficiency. Therefore, a high-pressure reactor with dual-disc temperature control is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-pressure reactor with dual-disc temperature control.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-pressure reactor with dual-disc temperature control, comprising a reactor body, a stirring rod rotatably connected to the inner top of the reactor body, multiple stirring paddles fixedly connected to the stirring rod, a motor housing fixedly connected to the upper surface of the reactor body, a servo motor fixedly connected to the bottom of the motor housing, the output shaft of the servo motor fixedly connected to one end of the stirring rod, a frequency converter fixedly connected to the upper surface of the motor housing, two ultrasonic transducers fixedly connected to symmetrical sides of the outer wall of the reactor body, a sampling tube fixedly connected to one side of the reactor body, and a manual control valve installed on the sampling tube. The operator can open the manual control valve on the sampling tube on one side of the reactor at any time to extract a small amount of reaction liquid for real-time monitoring and analysis, thereby accurately controlling the reaction process.

[0006] As a further description of the above technical solution:

[0007] The reactor body is equipped with an upper coil and a lower coil inside.

[0008] As a further description of the above technical solution:

[0009] One end of the lower coil is fixedly connected to the lower coil inlet, which penetrates one side of the reactor body and is fixedly connected. The other end of the lower coil is fixedly connected to the lower coil outlet, which penetrates the bottom of the reactor body and is fixedly connected. The lower coil, its lower coil inlet, and its lower coil outlet constitute another independent circulation channel for introducing a heat transfer medium to achieve precise temperature control of the material in the lower region of the reactor. Together with the upper coil, they form a dual-zone independent temperature control system.

[0010] As a further description of the above technical solution:

[0011] The bottom of the reactor body is fixedly connected to a discharge pipe, and a drain valve is installed on the discharge pipe. The discharge pipe and the drain valve are used to safely and completely discharge the material in the reactor after the reaction is completed or when needed.

[0012] As a further description of the above technical solution:

[0013] A solid feed inlet is fixedly connected to the upper surface of the reactor body. The solid feed inlet is equipped with a visualization window. The solid feed inlet is used to feed solid raw materials.

A first shut-off valve is installed on the liquid inlet. The liquid inlet, the storage tank, and the first shut-off valve work together to achieve the sealing, stability, and controllable addition of liquid materials, which helps to maintain the internal pressure and cleanliness of the reactor.

[0016] As a further description of the above technical solution:

[0017] A condenser port is fixedly connected to the upper surface of the reactor body. A stainless steel condenser is fixedly connected to one end of the condenser port. A second shut-off valve is installed on the condenser port. The stainless steel condenser is used to liquefy the gas in the material reaction process, and then the liquid in the stainless steel condenser is extracted through a water pumping pipe.

[0018] This utility model has the following beneficial effects:

[0019] 1. Compared with existing technologies, this high-pressure reactor with dual-disc temperature control uses an ultrasonic transducer electrically connected to an external ultrasonic generator. After the reaction is completed and the material is discharged, an appropriate amount of cleaning solvent is injected into the reactor body. Then, the ultrasonic generator connected to the ultrasonic transducer is activated by the controller. The ultrasonic transducer converts the high-frequency electrical signal into high-frequency mechanical vibration and transmits the ultrasonic energy to the cleaning liquid inside the reactor through the reactor wall. The strong ultrasonic waves generate tens of thousands of microbubbles in the liquid. The high-pressure shock waves generated when these microbubbles collapse instantly can effectively impact and peel off stubborn dirt, polymers, or catalyst particles adhering to the inner wall of the reactor, the stirring components, and all surfaces of the upper and lower coils, thereby improving cleaning efficiency.

[0020] 2. Compared with existing technologies, this high-pressure reactor with dual-disc temperature control, by setting up a sampling tube and a manual control valve, allows the operator to open the manual control valve on the sampling tube on one side of the reactor at any time during the reaction process to extract a small amount of reaction liquid for real-time monitoring and analysis, thereby accurately controlling the reaction process.
