Description

Technical Field

[0001] This utility model relates to the field of catalyst activity detection technology, and more specifically, to a catalyst preparation detection device. Background Technology

[0002] Catalysts play an irreplaceable and crucial role in modern chemical industry and numerous scientific research fields. They can significantly alter the rate of chemical reactions, lower the activation energy required for the reaction, and enable chemical reactions that would otherwise be difficult to occur or extremely slow under normal conditions to proceed efficiently. From the refining and cracking of oil products in petrochemicals to the synthesis of complex drug molecules in the pharmaceutical industry, from the conversion of harmful gases in automobile exhaust purification devices to the electrochemical reactions in fuel cells in the new energy field, catalysts are ubiquitous and are one of the core elements driving industrial progress, improving production efficiency, and achieving green and sustainable development.

[0003] Meanwhile, the catalyst performance testing process also faces numerous unresolved issues. When testing catalyst activity, insufficient mixing between the catalyst and reactants can lead to variations in catalyst-reactant contact conditions with each test. Even under identical conditions, significant fluctuations in test results can occur, compromising reproducibility. This lack of reliability hinders accurate evaluation and comparison of catalyst performance. Therefore, we propose a catalyst preparation and testing device. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example:

[0025] Please see Figure 1-4 A catalyst preparation and testing device includes a workbench 1, on which a reaction vessel 2 is mounted for catalyst preparation. A detection system 3 is connected to one side of the reaction vessel 2 for real-time monitoring and analysis of various parameters during the reaction process, such as temperature, pressure, reactant concentration, and product concentration, to promptly understand the reaction progress and evaluate catalyst performance. The detection system 3 includes a housing 301, inside which a reaction chamber is provided. The reaction chamber serves as the reaction chamber for catalyst performance testing. A feed pipe is connected to the reaction chamber to deliver the reactants required for catalyst testing. A temperature regulating chamber 302 is formed between the inner and outer walls of the housing 301, and a temperature regulating component is installed within the temperature regulating chamber 302 to adjust the temperature within the housing 301 as needed. A stirring component 4 is installed within the reaction chamber to ensure thorough mixing of the reactants and catalyst, improving the accuracy of catalyst testing.

[0026] The stirring assembly 4 includes a mounting shaft 404 and two sets of opposing stirring bars 401. The two sets of stirring bars 401 are distributed along the axial direction of the mounting shaft 404. Multiple stirring bars 401 on the same side have different lengths, and these different lengths generate different fluid velocities and shear forces during rotation. The combination of flow and shear forces at different scales accelerates the mixing of different components with the catalyst, improving mixing efficiency. The two opposing stirring bars 401 are tilted at different angles, which facilitates the mixing of the catalyst with the reactants or gases, generating forces in different directions during stirring, ensuring thorough mixing and reaction of the substances.

[0027] In one possible embodiment, the stirring bar 401 has an installation port, and an installation ring 402 is disposed within the installation port. Multiple inclined blades 403 are rotatably connected within the installation ring 402, and the multiple blades 403 are arranged in a ring inside the installation ring 402. The arrangement of the blades 403 further enables the stirring bar 401 to generate stirring forces in different directions when it rotates, facilitating thorough mixing of the reactants.

[0028] This application also includes a drive mechanism. A mounting frame 303 is provided inside the reaction chamber, and a mounting shaft 404 is rotatably connected to the mounting frame 303. The drive mechanism is located on the top of the mounting frame 303, and the output shaft of the drive mechanism is connected to the mounting shaft 404. The drive mechanism includes a motor, which drives the mounting shaft 404 to rotate, thereby driving multiple stirring strips 401 to rotate, so that the catalyst and reactants can be fully mixed.

[0029] In this application, the temperature regulation component includes pipes 5 arranged in a spiral pattern within the temperature regulation chamber 302. The pipes 5 are filled with liquid, and a constant-temperature water tank is installed in the housing 301. Both ends of the pipes 5 extend to the outside of the housing 301 and connect to the constant-temperature water tank. Water of different temperatures is introduced into the pipes 5 through the constant-temperature water tank to regulate the temperature inside the housing 301, thereby meeting the temperature required for the reaction. The constant-temperature water tank is equipped with a heating device and a temperature control system, which can precisely control the temperature of the water in the tank, maintaining it near the set temperature value, thus regulating the temperature inside the housing 301.

[0030] In this application, a filter chamber is provided above the reaction chamber, and a filter screen 6 with a conical structure is installed inside the filter chamber. A partition 7 is provided between the reaction chamber and the filter chamber, and a valve is provided in the middle of the partition 7. After the catalyst reacts with the reactants in the reaction chamber, if gas is generated, the valve in the middle of the partition 7 is opened to allow the gas to be discharged through the filter chamber. When the gas passes through the filter, the particulate matter carried in the gas is blocked by the filter screen 6. The bottom surface of the partition 7 can be set as an inclined surface on one side to facilitate the collection of filtered particulate matter. A discharge port is opened on one side of the bottom of the partition 7 for periodic cleaning of particulate matter.

[0031] In this application, the stirring bar 401 has multiple V-shaped grooves on its side. When the stirring bar 401 rotates, the liquid or gas forms a vortex in the V-shaped groove, generating additional shear force and turbulence, thereby enhancing the stirring force and making the stirring effect more significant.

[0032] In this application, a detection module is also provided inside the casing 301. The detection module is used to detect the temperature, pressure, reactant concentration, and product concentration inside the casing 301 in real time. The detection module includes a pressure sensor, a concentration sensor, a gas chromatograph, a liquid chromatograph, and a mass spectrometer. The gas chromatograph and liquid chromatograph can be used to analyze the composition and content of the reaction products, while the mass spectrometer can more accurately determine the molecular structure of the products.

[0033] In this application, a guide plate 8 is provided at the bottom of the shell 301. An inverted conical groove is provided on the top surface of the guide plate 8. The bottom of the groove is connected to a discharge pipe. A switch valve is provided on the discharge pipe. The discharge pipe facilitates the outward conveying of the reacted material.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
