Description

Technical Field

[0001] The present invention belongs to the technical field of chemical engineering, and specifically relates to a high-temperature and high-pressure test device. Background Art

[0002] In the research and industrial applications of chemical reaction processes, high-temperature and high-pressure reaction devices play a crucial role. These devices are commonly used in applications such as the synthesis of new materials, catalytic reactions, drug synthesis, and waste treatment. Traditional high-temperature and high-pressure reaction devices have some technical deficiencies, which limit their efficiency and safety in scientific research and industrial production;

[0003] Many existing high-temperature and high-pressure reaction devices adopt a single reaction chamber design, which only supports linear reaction steps. This design restricts the synchronous progress of multi-step reactions, resulting in an extended reaction time and low reaction efficiency. In addition, reactants at different stages in a single chamber may mix before reaching the optimal reaction conditions, thereby affecting the quality and yield of the final product; moreover, the gas-liquid interface monitoring technology of traditional high-temperature and high-pressure devices lags behind, lacking an effective online monitoring and control system. This leads to the inability to accurately control the feeding amount of materials in real time during the feeding and liquid supply processes, thus affecting the repeatability and accuracy of the reaction. Additionally, the uncertainty of fluid dynamics may cause the liquid level to be unable to be adjusted immediately, increasing the risk of overflow or incomplete reaction.

[0004] In a high-temperature and high-pressure environment, the release of gases and the overflow of liquids are common risks, and many existing devices lack effective safety prevention measures. The release of gases during the reaction process fails to be timely and effectively controlled, which may cause the pressure in the reaction vessel to rise abnormally, thereby triggering an explosion or equipment damage. In addition, the lack of a proper design of the venting system makes the collection and treatment of reaction products complex and unsafe. Moreover, the stirring or heating mechanisms of some existing devices cannot meet the requirements of high reaction rates, resulting in uneven distribution of reactants in the chamber. This unevenness may cause local overheating or incomplete reaction, thus causing side reactions and instability of the product properties.

[0005] Therefore, those skilled in the art have proposed a high-temperature and high-pressure test device, aiming to improve the reaction efficiency and improve the reaction effect by synchronously performing reactions in different steps. Summary of the Invention

Specific embodiments

[0024] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] As shown in the attached Figure 1 to the attached Figure 5 figures:

[0026] Embodiment 1: The present invention provides a high-temperature and high-pressure test device, including a box body 100, a feeding assembly 200 is arranged at the rear side above the box body 100, a liquid feeding assembly 300 is arranged at the upper rear side of the box body 100, a stirring and heating assembly 400 is arranged in the inner cavity of the box body 100, a pressurizing assembly 500 is arranged outside the box body 100 and is communicated with the inner cavity of the box body 100, and a venting assembly 600 is arranged at the lower rear side of the box body 100.

[0027] The inner cavity of the box body 100 is divided into three reaction chambers 103 by a titanium alloy partition, and the reaction chambers 103 are divided into independent chambers with a volume ratio of 1:1.2:1.5. Three groups of observation ports 101 are opened at the front side above the reaction chambers 103, and a feeding cup 102 is opened at the rear side above the box body 100.

[0028] The feeding assembly 200 includes a feeding hopper 201 arranged at the rear side above the box body 100. A material cover 202 is installed at the upper end of the feeding hopper 201. A rotary vane type level switch 203 is installed at the rear side of the feeding hopper 201. The rotary vane type level switch 203 uses a micro motor as the drive. At the output end of the rotary vane type level switch 203 and inside the feeding hopper 201, a blade 204 is arranged. When the blade 204 does not contact the powder used in the test, the motor runs normally and drives the blade 204 to rotate. When the blade 204 contacts the powder, the generated resistance overcomes the tension of the spring, causing the motor to stop rotating. When the powder drops, the resistance received by the blade 204 disappears, and it returns to the original state by relying on the tension of the torsion spring or the spring, preparing to respond to the rise of the powder again. That is, when the material rises to the position of the blade 204, the resistance causes the motor to stop rotating and outputs a signal to cut off the power supply. When the material drops, the resistance of the blade 204 disappears, and the signal detection device returns to the original state by relying on the spring, preparing to detect again. A vibrator 205 is arranged at the rear side of the feeding hopper 201 and below the rotary vane type level switch 203. The vibrator 205 eliminates the material wall sticking at a frequency of 50 Hz. By slightly vibrating the feeding hopper 201, the wall-sticking powder can fall off. A first motor 206 is fixedly installed above the box body 100 and on one side of the feeding hopper 201. At the output end of the first motor 206 and inside the feeding hopper 201, a spiral conveyor shaft 207 is fixedly installed. The outlet of the spiral conveyor shaft 207 is located above the feeding cup 102. The spiral conveyor shaft 207 accurately feeds materials at a rate of 0.5 - 2 kg / min. By operating the first motor 206, the spiral conveyor shaft 207 rotates, and the dropped powder is conveyed to the feeding cup 102 through the spiral conveyor shaft 207, and thus falls into the first reaction chamber 103 for primary reaction.

[0029] The liquid supply assembly 300 includes an infusion port 301 provided at the rear side of the box body 100. A Y-shaped filter 302, a pressure gauge 303, and a solenoid valve 304 are successively connected to the rear end of the infusion port 301 to form a liquid supply pipeline. A manual ball diaphragm valve 305 is installed at the rear end of the solenoid valve 304 on the liquid supply pipeline. And a pipe clamp 306 is fixedly installed at the rear end of the box body 100 for clamping the liquid supply pipeline. The outlets of the liquid supply pipeline are respectively provided with a first infusion tube 307 and a second infusion tube 308. The first infusion tube 307 is directly connected to the reaction chamber 103 above the box body 100, and the second infusion tube 308 is connected to one side of the feeding cup 102. The reaction liquid is input through the infusion port 301, passes through the Y-shaped filter 302, is detected by the pressure gauge 303 and controlled by the solenoid valve 304, so that the reaction liquid can be detected and controlled for input. Then, the flow rate and pressure of the liquid medium are controlled by the manual ball diaphragm valve 305. The output reaction liquid is directly input into the first reaction chamber 103 through the first infusion tube 307, and also combines with the powder dropped from the screw conveyor shaft 207 in the feeding cup 102 through the second infusion tube 308 and then drops into the first reaction chamber 103. Multiple groups of ball valves are provided on the liquid supply assembly 300 for controlling the liquid flow and transportation.

[0030] The stirring and heating assembly 400 includes a second motor 401 disposed on the front side above the box body 100. There are three groups of the second motors 401, which are respectively located above the three reaction chambers 103. A stirring shaft 402 is fixedly installed at the output end of the second motor 401 and located in the corresponding reaction chamber 103. Stirring blades 403 are arranged on the stirring shaft 402. The stirring blades 403 adopt an asymmetric airfoil design. Referring to the GB / T 19077-2016 standard, the measured mixing efficiency reaches 98.7%. Heating plates 404 are arranged at the bottom of each reaction chamber 103. The inner cavity of the box body 100 is divided into three reaction chambers 103 by a titanium alloy partition. An overflow pipe 405 is arranged on one side of the reaction chamber 103 below the feed cup 102. And C-shaped grooves 406 are fixedly installed on one side of the titanium alloy partition. A flow port is arranged at one side of the lower end of the C-shaped groove 406 through the titanium alloy partition. The height of the overflow pipe 405 is greater than the height of the C-shaped groove 406. A liquid level controller 407 is fixedly arranged above the reaction chamber 103 communicating with the pressurizing assembly 500. By starting the heating plate 404, the reaction liquid and the powder are fused and reacted. And by starting the second motor 401, the stirring shaft 402 drives the stirring blades 403 to stir in the reaction chamber 103, accelerating the reaction rate. And the excess liquid is discharged through the overflow pipe 405 to prevent the liquid in the reaction chamber 103 from being too much, resulting in the risk of swelling. And through the C-shaped groove 406 on one side of the titanium alloy partition, the fused liquid after the initial reaction in the first reaction chamber 103 is introduced into the second reaction chamber 103. After being heated by the heating plate 404 and stirred by the stirring shaft 402, a secondary reaction is carried out. After the reaction, it flows into the third reaction chamber 103 through the C-shaped groove 406 on one side of the titanium alloy partition. The temperatures of the heating plates 404 in the three reaction chambers 103 can be set independently, so as to carry out a three-stage reaction. And a pressurizing assembly 500 is connected in the third reaction chamber 103 for high-pressure treatment.

[0031] The pressurizing assembly 500 includes a bracket 501. A pressurizing pump 502 is fixedly installed at the upper end of the bracket 501. A pressurizing pipe 503 is fixedly installed at the output end of the pressurizing pump 502. The top end of the pressurizing pipe 503 penetrates through the box body 100, and a pressurizing port 504 is opened at the lower end on one side of the reaction chamber 103. By starting the pressurizing pump 502, the third reaction chamber 103 connected thereto is in a high-pressure state. At the same time, the overall reaction chamber 103 is in a high-pressure state through the C-shaped groove 406. Thus, all three reactions are in a high-pressure state. Due to the volume of the reaction chamber 103, the pressurizing method adopts a three-stage progressive pressurization design, which is 5MPa → 15MPa → 30MPa. After being verified by ANSYS simulation, the pressure distribution uniformity is increased by 42%.

[0032] The venting assembly 600 includes vent openings 601 provided at the lower rear sides of three reaction chambers 103 of the box body 100. The vent openings 601 are respectively communicated with a first branch pipe 602, a second branch pipe 603, and a third branch pipe 604. The first branch pipe 602, the second branch pipe 603, and the third branch pipe 604 are communicated through a vent main pipe 605, and one end of the vent main pipe 605 is provided with a main pipe outlet 606. By combining the overflow pipe 405 with the venting assembly 600, dual redundant pressure relief is formed for effective safety protection. The reaction solution in each chamber is controlled to flow out through the ball valves on all branch pipes, so as to orderly collect the solutions at different stages in the three reaction chambers 103.

[0033] Based on the verification of the pilot production line, the following experimental data are obtained:

[0034] index A traditional device Device of the present invention Improvement rate Reaction efficiency 72％ 93％ 29.2％ Energy intensity 8.7kW·h / kg 5.2kW·h / kg 40.2％ Product consistency ±6.8％ ±1.5％ 78％

[0035] It has been implemented in a certain special polymer synthesis project (with an annual output of 5,000 tons), achieving: the reaction cycle is shortened from 14 hours to 9.5 hours, the annual accident rate is reduced from 1.2% to 0.15%, and the qualified rate of product crystal form is increased from 82% to 97%.

[0036] As can be seen from the above, by dividing the reaction chamber into three independent areas, the device can realize the synchronous progress of different reaction steps, improve the reaction efficiency of the system, and the stirring and heating assembly ensures that the reactants are evenly mixed in each reaction chamber and obtain a suitable reaction temperature, further improving the reaction rate. And the feeding assembly and the liquid supply assembly are equipped with a variety of sensors and control systems, which can realize the automatic monitoring and control of the feeding amounts of materials and liquids, improve the accuracy of the experiment. The liquid level controller monitors the liquid level in the reaction chamber to ensure an appropriate amount of liquid, prevent overflow and incomplete reaction. At the same time, the pressurizing assembly ensures that the three reactions are in a high-pressure state through a pressure pump, improving the reaction efficiency while reducing the risk of gas release. The design of the venting assembly enables the solutions in each reaction chamber to be discharged orderly, avoiding danger caused by excessive liquid, and facilitating subsequent experimental data collection. Therefore, the device can be applied to different types of chemical reactions, especially reactions that require the combination of high temperature, high pressure and stirring, and is very suitable for research fields such as material synthesis and chemical synthesis.
