Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a distillation tower for distilling and recovering diuron wastewater. Background Technology

[0002] Diuron is a widely used herbicide, and its production process generates a large amount of wastewater containing diuron and its byproducts. In order to make rational use of diuron wastewater, it is necessary to purify the wastewater by distillation in a distillation tower to recover high concentrations of diuron herbicide. This process can not only reduce the pollution of wastewater to the environment, but also realize the recycling of resources and reduce production costs.

[0003] Diuron wastewater contains soluble salts of metal ions such as calcium and magnesium. During the distillation process, as water evaporates, the concentration of these salts gradually increases. When they reach saturation, they can precipitate from the wastewater and deposit on the inner wall of the distillation tower, forming scale. This scale forms an insulating layer on the inner wall of the distillation tower, hindering heat transfer and thus reducing distillation efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a distillation tower for distilling and recovering diuron wastewater, including a distillation tower, an internal stirring assembly and a driving assembly, the driving end of the driving assembly being connected to the stirring assembly, the stirring end of the stirring assembly being provided with a scraper, and a filter assembly being provided at the bottom of the distillation tower.

[0008] The driving component is used to drive the stirring component, so that the stirring component stirs the diuron wastewater while driving the scraper to rotate. The rotating scraper is used to scrape and clean the scale on the inner wall of the distillation tower. The filtration component is used to collect the scale and impurities in the wastewater.

[0009] Furthermore, the stirring assembly includes a rotating tube, which is rotatably connected to the inner wall of the distillation column.

A driven gear is fixedly connected to the outer surface of the drive ring, and a drive gear meshes with the outer surface of the driven gear. A motor is fixedly installed on the outer surface of the distillation column, and the output end of the motor is fixedly connected to the drive gear.

[0011] Furthermore, a sealing groove is provided on the inner wall of the distillation column, and a sealing ring is rotatably connected inside the sealing groove. The sealing ring is fixedly connected to the outer surface of the rotating tube.

[0012] Furthermore, the filtration assembly includes a connecting pipe, which is fixedly installed at the bottom of the distillation column.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a drive component to rotate a stirring component, which causes a scraper to scrape the inner wall of the distillation column under the action of the stirring component. This design can prevent scale formation on the inner wall of the distillation column, thus ensuring the effectiveness of the heating device in heating diuron wastewater through the distillation column. At the same time, because the stirring component can continuously stir the diuron wastewater inside the distillation column, the heat in the diuron wastewater can be evenly distributed, reducing the thermal boundary layer thickness, enhancing convective heat transfer, and preventing local boiling. In summary, the combination of the stirring component and the scraper can significantly improve the efficiency of the distillation column in distilling diuron wastewater.

[0017] 2. This utility model uses a solenoid valve to drive the liquid that has been distilled and purified inside the distillation tower to flow into the filter box through the connecting pipe. At this time, the filter holes at the bottom of the filter box filter the impurities and scale carried by the liquid. The filtered liquid is then discharged directly from the inside of the filter box through the discharge pipe. The filter box design ensures the purity of the liquid discharged from the filter box. At the same time, since the filter box can be directly pulled out from the inside of the filter box, it is also convenient to clean the filtered impurities and scale.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is a distillation tower for distilling and recovering diuron wastewater, including a distillation tower 1. The distillation tower 1 is equipped with a stirring assembly 2 and a driving assembly 3. The driving end of the driving assembly 3 is connected to the stirring assembly 2. The stirring end of the stirring assembly 2 is equipped with a scraper 4. The bottom of the distillation tower 1 is equipped with a filter assembly 5.

[0032] The driving component 3 is used to drive the stirring component 2 so that the stirring component 2 stirs the diuron wastewater while driving the scraper 4 to rotate. The rotating scraper 4 is used to scrape and clean the scale on the inner wall of the distillation tower 1. The filtration component 5 is used to collect the scale and impurities in the wastewater.

[0033] During the distillation of diuron wastewater, the drive component 3 drives the stirring component 2 to rotate inside the distillation tower 1, thereby stirring the diuron wastewater inside the distillation tower 1. At the same time, the scraper 4, driven by the stirring end of the stirring component 2, scrapes off the scale on the inner wall of the distillation tower 1. After the distillation and purification of diuron wastewater is completed, the liquid inside the distillation tower 1 is discharged through the filter component 5. At this time, the filter component 5 filters and collects the impurities inside the liquid and the scale that has been cleaned off.

[0034] The drive assembly 3 drives the stirring assembly 2 to rotate, causing the scraper 4 to scrape the inner wall of the distillation tower 1 under the action of the stirring assembly 2. This design can prevent scale formation on the inner wall of the distillation tower 1, thus ensuring the effectiveness of the heating device in heating the diuron wastewater through the distillation tower 1. At the same time, since the stirring assembly 2 can continuously stir the diuron wastewater inside the distillation tower 1, the heat in the diuron wastewater can be evenly distributed, the thermal boundary layer thickness is reduced, convective heat transfer is enhanced, and local boiling is prevented. In summary, the combination of the stirring assembly 2 and the scraper 4 can significantly improve the efficiency of the distillation tower 1 in distilling diuron wastewater.

[0035] In one embodiment, the stirring assembly 2 includes a rotating tube 201, which is rotatably connected to the inner wall of the distillation column 1. A support frame 202 is fixedly connected to the inner wall of the rotating tube 201. A rotating shaft 203 is fixedly installed at the bottom of the support frame 202. A plurality of stirring rollers 204 are fixedly connected to the outer surface of the rotating shaft 203. The scraper 4 is fixedly connected to one end of the stirring rollers 204.

[0036] By rotating the rotating tube 201, the rotating tube 201 drives the rotating shaft 203 and the stirring roller 204 to rotate inside the diuron wastewater through the support frame 202. This allows the stirring roller 204 to stir the diuron wastewater. At the same time, the scraper 4 rotates on the inner wall of the distillation tower 1 under the drive of the stirring roller 204, which makes it difficult for scale to form on the inner wall of the distillation tower 1.

[0037] In one embodiment, the drive assembly 3 includes a drive groove 301, which is formed on the inner wall of the distillation column 1. A drive ring 302 is rotatably connected inside the drive groove 301. The drive ring 302 is fixedly connected to the rotating tube 201. A driven gear 303 is fixedly connected to the outer surface of the drive ring 302. A drive gear 304 meshes with the outer surface of the driven gear 303. A motor 305 is fixedly installed on the outer surface of the distillation column 1. The output end of the motor 305 is fixedly connected to the drive gear 304.

[0038] By driving the motor 305, the motor 305's gear shifting drive gear 304 rotates inside the drive groove 301. The rotating drive gear 304 drives the drive ring 302 to rotate together through the driven gear 303, thereby enabling the drive ring 302 to drive the rotating tube 201 to rotate inside the distillation column 1. Since the rotating tube 201 can shield the drive groove 301 as a whole, and the rotating tube 201 is in close contact with the inner wall of the distillation column 1, the diuron wastewater inside the distillation column 1 is prevented from flowing into the drive groove 301.

[0039] In one embodiment, for the distillation column 1 described above, a sealing groove 306 is provided on the inner wall of the distillation column 1, and a sealing ring 307 is rotatably connected inside the sealing groove 306. The sealing ring 307 is fixedly connected to the outer surface of the rotating tube 201.

[0040] The sealing groove 306 is provided on both the upper and lower sides of the drive groove 301. When the rotating tube 201 rotates, it can drive the two sealing rings 307 to rotate inside the corresponding sealing groove 306. At this time, the sealing groove 306 and the sealing ring 307 cooperate with each other to improve the sealing effect of the rotating tube 201 on the drive groove 301.

[0041] In one embodiment, the filter assembly 5 includes a connecting pipe 501, which is fixedly installed at the bottom of the distillation column 1. A filter box 502 is fixedly installed at the bottom end of the connecting pipe 501. A through groove 503 is provided on one side of the filter box 502. A support frame 504 is fixedly connected to the inner wall of the filter box 502 corresponding to the through groove 503. A filter box 505 is slidably connected to the inside of the through groove 503 and the support frame 504. A filter hole 506 is provided at the bottom of the inner wall of the filter box 505. A discharge pipe 507 is fixedly connected to the bottom of the filter box 502.

[0042] After the distillation and purification of the diuron wastewater inside the distillation tower 1 is completed, the purified liquid can flow into the filter box 502 through the connecting pipe 501. At this time, the filter holes 506 at the bottom of the filter box 505 can filter out the impurities and scale carried in the liquid. The filtered liquid is then discharged directly through the discharge pipe 507. The above settings ensure the purity of the discharged liquid. When it is necessary to clean the filtered impurities and scale, the filter box 505 can be pulled directly, so that the filter box 505 moves out of the support frame 504 and the filter box 502 through the through groove 503. Then, the collected impurities and scale are cleaned from the outside of the filter box 502.

[0043] In one embodiment, for the connecting pipe 501, a solenoid valve 508 is provided inside the connecting pipe 501, a support leg 509 is fixedly installed on the outer surface of the distillation column 1, the filter box 502 is fixedly installed on the inner wall of the support leg 509, a limit frame 510 is fixedly installed on the top of the filter box 502, and a U-shaped limit plate 511 is movably connected inside the limit frame 510.

[0044] By driving the solenoid valve 508, the liquid that has been distilled and purified inside the distillation column 1 can flow through the connecting pipe 501 into the filter box 502. The support leg 509 can fix and support the distillation column 1 and the filter box 502, so that the connection between the two is relatively firm. At the same time, the overall stability of the distillation column can be guaranteed when treating diuron wastewater. When the filter box 505 is inside the filter box 502, the U-shaped limiting plate 511 is pulled downward, so that the U-shaped limiting plate 511 contacts the outside of the filter box 505. At this time, the U-shaped limiting plate 511 can limit the filter box 505 inside the filter box 502 through the limiting frame 510, so that the filter box 505 will not move out of the filter box 502 when filtering impurities and scale in the liquid.

[0045] In one embodiment, the distillation column 1 is provided with an arc-shaped top, a steam discharge pipe 6 is fixedly connected to the top of the distillation column 1, and a feed pipe 7 is fixedly connected to the outer surface of the distillation column 1.

[0046] Diuron wastewater requiring distillation and purification can be discharged into the interior of distillation tower 1 through feed pipe 7. When the diuron wastewater inside distillation tower 1 is heated and forms steam, the steam can float upwards. At the same time, the steam is guided by the arc-shaped top of the distillation tower to the interior of steam discharge pipe 6 and discharged from the interior of distillation tower 1 through steam discharge pipe 6. Steam discharge pipe 6 is connected to a cooling device, so that the steam can be cooled by the cooling device to form pure water.

[0047] Through the above technical solution, 1. The driving component 3 drives the stirring component 2 to rotate, so that the scraper 4 scrapes the inner wall of the distillation tower 1 under the action of the stirring component 2. This setting can prevent scale formation on the inner wall of the distillation tower 1, thereby ensuring the effectiveness of the heating device in heating the diuron wastewater through the distillation tower 1. At the same time, since the stirring component 2 can continuously stir the diuron wastewater inside the distillation tower 1, the heat in the diuron wastewater can be evenly distributed, the thermal boundary layer thickness is reduced, convective heat transfer is enhanced, and local boiling is prevented. In summary, the combination of the stirring component 2 and the scraper 4 enables the distillation tower 1 to effectively heat the diuron wastewater. 1. The efficiency of distillation can be significantly improved; 2. By driving the solenoid valve 508, the liquid that has been distilled and purified inside the distillation column 1 flows into the filter box 502 through the connecting pipe 501. At this time, the filter holes 506 at the bottom of the filter box 505 filter the impurities and scale carried by the liquid. The filtered liquid is directly discharged from the inside of the filter box 502 through the discharge pipe 507. The filter box 505 ensures the purity of the liquid discharged from the inside of the filter box 502. At the same time, since the filter box 505 can be directly pulled out from the inside of the filter box 502, it is also convenient to clean the filtered impurities and scale.
