Description

Technical Field

[0001] This utility model relates to the technical field of water treatment devices, and in particular to a special treatment device for acidic water from crude benzene hydrogenation. Background Technology

[0002] The acidic water treatment unit for crude benzene hydrogenation is mainly used to remove impurities and acidic substances contained in crude benzene, improve the purity of crude benzene, and ensure the smooth progress of subsequent hydrogenation processes. This unit usually uses acidic water to adsorb or chemically react with impurities in crude benzene to achieve purification. It has a wide range of applications, especially in the petrochemical and fine chemical industries, and is of great significance for improving product quality and reducing environmental pollution.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing dedicated treatment equipment for acidic water from crude benzene hydrogenation cannot achieve efficient treatment of acidic water and automatic cleaning of precipitates. Due to the inability to efficiently treat acidic water, the treatment equipment needs to be frequently shut down for maintenance and precipitate cleaning. The inefficient operation of the treatment equipment means that its actual working time is reduced, and the time the equipment spends in inefficient operation or shutdown is increased. This leads to a decrease in equipment utilization and a decline in the return on investment for enterprises. If acidic water is not treated efficiently, the impurities and organic matter it contains may enter subsequent production stages with the water flow. This will have an adverse impact on subsequent hydrogenation reactions, product separation, and other processes, resulting in unstable product quality and an increased defect rate.

[0004] Therefore, this utility model proposes a special treatment device for acidic water from crude benzene hydrogenation to solve the above problems. Utility Model Content

The two work together to achieve continuous inflow and outflow of liquid, ensuring the continuity and efficiency of the treatment process.

[0016] Furthermore, the second inlet is fixed to the first outlet, and the filter has a second outlet fixed on one side near the bottom.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the filter is connected to the first discharge port through the second inlet to receive the liquid discharged from the tank. The filter is equipped with a filter medium inside, which can remove suspended solids and impurities in the liquid, further improve the purity of the liquid, and provide a guarantee for subsequent treatment or discharge.

[0018] Furthermore, a support block is fixed on the tank body, a sealing gasket is fixed on the top of the collection box, a connecting plate is fixed on the collection box, and the connecting plate is disposed inside the support block.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1-5 As shown, this embodiment provides a technical solution: a special treatment device for acidic water from crude benzene hydrogenation, comprising:

[0035] Base plate 1;

[0036] Processing component 2 is placed on top of base plate 1. Processing component 2 includes a tank 21 fixed on top of base plate 1. A tank cover 22 is provided on top of tank 21. A drive motor 24 is installed on tank cover 22. A rotating shaft 25 is fixed to the output end of drive motor 24. A spiral blade 26 is fixed on the side of rotating shaft 25 near the top.

A discharge chute 33 is provided at the bottom of tank 21, and a collection box 35 is provided on the side of the bottom of tank 21 near the discharge chute 33. After acidic water enters tank 21 through the first inlet 213, the drive motor 24 starts, driving the rotating shaft 25 to rotate. A spiral blade 26 and a second agitator are installed on the rotating shaft 25. The paddle 29 rotates accordingly, thoroughly stirring the liquid inside the tank 21, promoting mixing and mass transfer between reactants, thereby improving reaction efficiency. Simultaneously, a support rod 27 and the first stirring paddle 28 are fixed on the rotating shaft 25, forming a multi-layered stirring structure to further enhance the stirring effect, ensuring uniform heating and reaction of the liquid. The steam generator 210 supplies steam to the tank 21 through the connecting pipe 211. The steam input not only regulates the temperature inside the tank 21 but also accelerates the chemical reaction process, improving processing efficiency. The valve 212 on the pipe 211 is used to precisely control the steam flow rate and ensure the stability of temperature regulation. During the treatment process, suspended solids and precipitates generated by the reaction in the liquid gradually settle at the bottom of the tank 21. The support plate 31 at the bottom of the rotating shaft 25 drives the scraper 32 to rotate, scraping the deposited precipitates into the discharge trough 33 at the bottom of the tank 21. The precipitates enter the collection box 35 for centralized treatment through the discharge trough 33. The collection box 35 is fixed to the tank 21 by the connecting plate 37 and bolts 38. The sealing gasket 36 ensures the sealing between the collection box 35 and the tank 21 to prevent leakage.

The filter 215 is connected to the first discharge port 214 through the second inlet port 216 to remove tiny suspended solids and impurities in the liquid. Finally, it is discharged through the second discharge port 217, completing the entire treatment process. This achieves efficient treatment of acidic water and automatic cleaning of precipitates, significantly improving treatment efficiency and ease of operation, while reducing manual maintenance costs.

The sealing ring 23 is fixed to the bottom of the can lid 22 to ensure the sealing between the can body 21 and the can lid 22, preventing liquid or gas leakage during the process. Its elastic material can adapt to the pressure changes inside the can body 21, while reducing the entry of external contaminants and ensuring the cleanliness and safety of the process. A support rod 27 is fixed on the side of the rotating shaft 25 near the top of the second stirring paddle 29. A first stirring paddle 28 is fixed on the support rod 27. The support rod 27 is fixed on the rotating shaft 25 to support the first stirring paddle 28. The first stirring paddle 28 rotates under the drive of the rotating shaft 25 to stir the liquid in the can body 21, promote the mixing and mass transfer of reactants, and improve the processing efficiency.

The first discharge port 214 is located at the bottom of the tank 21 and is used to discharge the treated liquid. The two work together to achieve continuous liquid inflow and outflow, ensuring the continuity and efficiency of the treatment process. The second inlet 216 is fixed on the first discharge port 214. A second discharge port 217 is fixed on the side of the filter 215 near the bottom. The filter 215 is connected to the first discharge port 214 through the second inlet 216 and is used to receive the liquid discharged from the tank 21. The filter 215 is equipped with a filter medium inside, which can remove suspended solids and impurities in the liquid, further improve the purity of the liquid, and provide a guarantee for subsequent treatment or discharge.

[0040] like Figures 1-5As shown, after acidic water enters the tank 21 through the first inlet 213, the drive motor 24 starts, driving the rotating shaft 25 to rotate. The spiral blades 26, the first stirring paddle 28, and the second stirring paddle 29 mounted on the rotating shaft 25 rotate accordingly, forming a multi-layered stirring structure.

In response, the steam generator 210 supplies steam to the tank 21 through the connecting pipe 211. The steam input not only regulates the temperature inside the tank 21 but also accelerates the chemical reaction process and improves processing efficiency. The valve 212 on the connecting pipe 211 is used to precisely control the steam flow rate and ensure the stability of temperature regulation. The sealing ring 23 at the bottom of the tank cover 22 ensures the seal between the tank 21 and the tank cover 22, preventing liquid or gas leakage during processing and reducing the entry of external contaminants, thus ensuring the cleanliness and safety of the processing. Gas can enter from the first feed. The liquid is discharged from outlet 213 for collection. During the treatment process, suspended solids and precipitates generated from the reaction gradually settle at the bottom of tank 21. The support plate 31 at the bottom of the rotating shaft 25 drives the scraper 32 to rotate, scraping the settled precipitates into the discharge trough 33 at the bottom of tank 21. The precipitates enter the collection box 35 for centralized treatment through the discharge trough 33. The collection box 35 is fixed to tank 21 by connecting plate 37 and bolts 38. The sealing gasket 36 ensures the sealing between the collection box 35 and tank 21 to prevent leakage, while also facilitating disassembly and cleaning.
