Description

Technical Field

[0001] This utility model relates to the technical field of catalyst storage equipment, specifically a catalyst storage device for coal chemical industry. Background Technology

[0002] In coal chemical production processes, the activity and stability of catalysts (such as Fischer-Tropsch synthesis catalysts, methanol synthesis catalysts, and hydrogenation catalysts) are crucial to reaction efficiency. However, improper temperature control in the catalyst storage environment can lead to deactivation due to temperature fluctuations. High temperatures can easily cause catalyst sintering, while low temperatures may cause moisture absorption or phase changes, and there is also the problem of localized thermal unevenness. Traditional single-path temperature control methods can easily result in uneven temperature distribution within the storage tank, affecting catalyst performance. Therefore, this application proposes a catalyst storage device for coal chemical industry to solve the above problems. Utility Model Content

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1-6As shown, this utility model provides a technical solution: a catalyst storage device for coal chemical industry, comprising multiple storage tanks 1. Pipes 2 are installed on both the left and right sides of the top of each storage tank 1, and pipes 3 are installed on both the left and right sides of the bottom of each storage tank 1. Multiple temperature-controlled pipes 4 connect the vertically opposite pipes 2 and 3. These temperature-controlled pipes 4 are distributed in a dispersed manner, and all temperature-controlled pipes 4 are thin tubes. The number of temperature-controlled pipes 4 between pipes 2 and 3 is four or more. Pipes 1-2 and 2-3 at the bottom are respectively connected to main pipe 1-5 and main pipe 2-7. One end of main pipe 1-5 on the left is connected to the medium pump outlet of the temperature control equipment, and a solenoid valve is installed at the connection. Both ends of main pipe 1-5 on the right are connected to the medium pump outlet and the medium return end of the temperature control equipment, respectively, and a solenoid valve is installed at the connection. The two main pipes 2-7 are connected to the medium return end of the temperature control equipment. A return pipe 9 is connected between the two pipes 2-3. Solenoid valves 1-6, 2-8, and 3-10 are respectively installed on pipes 1-2, 2-3, and return pipe 9. The return pipe 9 is installed at the... The temperature monitoring module 11 is installed inside the storage tank 1, which is positioned higher than the solenoid valve 28. Insulation layers are provided on the outer walls of the storage tank 1, the outer walls of pipes 1 and 2 (located on the outer side of the storage tank 1), and the outer wall of the main pipe 5. When the temperature-controlled medium enters the storage tank 1 through the left-side pipe 12, flows through multiple dispersed temperature-controlled pipes 4 to pipe 23, and finally returns to the temperature control device through the main pipe 27, a single-sided flow mode can be achieved. Alternatively, the temperature-controlled medium can enter the storage tank 1 from both sides of the main pipe 15, flow bidirectionally through the temperature-controlled pipes 4, and finally return to the temperature control device through the main pipe 27 and the medium return end. The equipment implements a dual-sided flow mode, enhancing the temperature uniformity of storage tank 1. The temperature control medium forms a reflux circulation within storage tank 1, sequentially passing through the left-side temperature control pipe 4, the return pipe 9, and the right-side temperature control pipe 4, and finally returning to the temperature control equipment through the right-side main pipe 5 and the medium return end. This allows for the selection of the appropriate flow mode based on the storage tank's insulation requirements, ensuring the temperature control accuracy and reliability of catalyst storage in the storage tank. It is particularly suitable for scenarios in the coal chemical industry with stringent requirements for high temperature, oxidation prevention, and uniformity, providing an efficient solution for large-scale industrial catalyst management.

[0024] The operational steps for this application are as follows:

[0025] Turn on the temperature control device, set the target temperature range, and the temperature monitoring module 11 is used to monitor the real-time temperature in the storage tank 1. Start the medium pump so that the temperature control medium, such as heat transfer oil or water, flows from the pump outlet of the temperature control device into the left main pipe 5.

[0026] like Figure 3As shown, in the single-sided flow mode, the solenoid valve 6 on the left pipe 1 2 and the solenoid valve 8 on the corresponding pipe 2 3 are opened, the solenoid valve on the right pipe 1 2 connected to the outlet of the medium pump is closed, and the solenoid valve 10 on the return pipe 9 is closed; the temperature-controlled medium enters the storage tank 1 through the left pipe 1 2, flows to the pipe 2 3 through multiple dispersed temperature control pipes 4, and finally returns to the temperature control equipment through the main pipe 2 7. This is suitable for daily temperature control of the storage tank 1 and greatly reduces the energy consumption of the temperature control equipment.

[0027] like Figure 5 As shown, the dual-flow mode is suitable for rapid temperature adjustment. Simultaneously, solenoid valves 6 and 8 on pipes 1-2 and 3 on both sides are opened, while solenoid valve 10 on the return pipe 9 is closed. The solenoid valve on the right side of pipe 1-2 connected to the medium return end is also closed. The temperature-controlled medium enters the storage tank 1 from the two main pipes 5, flows bidirectionally through the temperature control pipe 4, and finally returns to the temperature control equipment through the main pipe 7 and the medium return end. This enhances the temperature uniformity of the storage tank 1 and is suitable for rapid temperature control and adjustment of the storage tank 1.

[0028] In reflux mode, open solenoid valve 10 on reflux pipe 9 and close solenoid valve 8 on pipe 23. Close the solenoid valve on the right side of pipe 12 that connects to the outlet of the medium pump. Figure 4 As shown, the temperature control medium forms a reflux circulation in the storage tank 1, passing sequentially through the left temperature control pipe 4, the return pipe 9, and the right temperature control pipe 4, and finally returning to the temperature control equipment through the right main pipe 5 and the medium return end. This increases the flow distance of the temperature control medium in the storage tank 1, maximizing the utilization of the heat energy or cold source carried by the temperature control medium.
