Description

Technical Field

[0001] This invention relates to the field of wet electronic chemical separation and purification technology, specifically to a wet electronic chemical separation and purification apparatus and method. Background Technology

[0002] The distillation and purification of wet electronic chemicals generally employs fixed bulk packing or structured packing distillation columns. During operation, heavy components and high-boiling-point impurities such as metal ions, stabilizer decomposition products, photoresist residues, and high-temperature polymers contained in the raw materials inevitably precipitate, adsorb, and gradually accumulate on the packing surface, leading to a rapid decrease in the effective mass transfer area of ​​the packing and a sharp increase in pressure drop. Typically, after 30 to 90 days of operation, severe blockage occurs in the packing section, and the column pressure difference can soar from the initial 3 to 5 kPa to 30 to 80 kPa. In severe cases, it can even lead to flooding and loss of product control, necessitating frequent shutdowns for column dismantling, cleaning, or packing replacement.

[0003] Existing separation and purification technologies attempt to alleviate clogging by increasing the reflux ratio, increasing the number of theoretical plates, or performing regular chemical cleaning. However, these methods can only slightly extend the cleaning cycle. Furthermore, the cleaning process requires the use of large amounts of acids, alkalis, or organic solvents, which can easily introduce new metal ions and particulate contamination. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a wet electronic chemical separation and purification apparatus and method to solve the problem of clogging in existing distillation column packing.

[0005] This invention is achieved through the following technical solution: A wet electronic chemical separation and purification device includes a protective shell, a driving structure installed on the lower side of the protective shell, an array of flow guiding structures installed inside the protective shell, a rotating packing corresponding to the flow guiding structures installed on the driving structure, a cleaning brush installed inside the flow guiding structures, the rotating packing rotating with the driving structure, and a partition plate installed inside the protective shell. The drive structure includes a support tower base installed at the bottom of the protective shell, a drive motor installed inside the support tower base, a drive shaft installed on the output shaft of the drive motor, a rotating packing array installed on the drive shaft, and the rotating packing slidingly engaging with the cleaning brush. The flow guiding structure includes an array of isolation mounting tubes mounted on the inner contour of the protective housing, a guide plate mounted on the isolation mounting tubes, and a liquid receiving component mounted on the upper side of the guide plate.

[0006] Preferably, the top of the protective housing is equipped with an inlet pipe for inputting the solution, and the top of the protective housing is equipped with an outlet pipe for outputting gas.

[0007] Preferably, a drain pipe is installed on the lower side of the support tower, the drain pipe is connected to the upper end of the support tower bottom, the drain pipe is connected to the liquid inlet pipe at the top of the protective shell, and a truncated cone with an inclined surface is provided in the middle of the support tower bottom.

[0008] Preferably, a guide ring is installed on the upper end of the liquid receiving component, the upper end of the guide ring has an inclined structure, and a through hole is opened on the liquid receiving component, the through hole on the liquid receiving component corresponding to the cleaning brush is closed.

[0009] Preferably, a cleaning guide ring is slidably connected inside the isolation installation tube, the upper end of the cleaning guide ring is an inclined surface, and the slope of the inclined surface of the cleaning guide ring is consistent with that of the corresponding guide ring.

[0010] Preferably, the bottom diameter of the guide plate is larger than the diameter of the isolation installation tube, there is a gap between the guide plate and the protective shell, and the diameters of the liquid receiving component, the guide ring and the cleaning guide ring are the same.

[0011] Preferably, a symmetrically distributed intermittent transmission structure is installed inside the protective housing. The intermittent transmission structure includes symmetrically arrayed support plates slidably connected to the inner contour of the protective housing. Connecting rods are installed between the support plates. Limiting sliders are installed on the side of each support plate closest to the protective housing. The limiting sliders are slidably connected to the protective housing. A groove is provided on the protective housing corresponding to the limiting slider. The support plates are fixedly installed to the lower end of a cleaning guide ring, and the cleaning guide ring slidably engages with a corresponding guide ring. Preferably, an air intake pipe distributed on the vehicle is installed through the protective housing. A rotating fan blade is rotatably connected inside the air intake pipe. A rotating rod is installed at the upper end of the rotating fan blade. The rotating rod is rotatably connected through the air intake pipe. A control ring is installed on the rotating rod. A support rod is slidably connected inside the rotating rod. An adjusting slider that slidably cooperates with the control ring is installed on the support rod.

[0012] Preferably, the control ring has a recessed groove, a tension spring is provided between the support rod and the rotating rod, the support rod is rotatably connected to the partition plate, and the support rod is supported and cooperated with the support plate on the lower side.

[0013] This invention also provides a method for separating and purifying wet electronic chemicals, comprising the following steps: S1. The drive shaft is driven by the drive motor to rotate, which in turn causes the rotating packing to rotate synchronously with the drive shaft. The processing solution enters from the liquid inlet pipe at the top of the protective shell, and the processing gas enters from the gas inlet pipe. They converge in the rotating packing for processing. S2. During the processing of the solution, solid impurities will be generated and adhere to the rotating packing. Then, through the friction between the rotating packing and the cleaning brush, the newly attached impurities are scraped off by the cleaning brush. Combined with the upward movement of the gas and the centrifugal force generated by the rotation of the packing, the impurities are discharged out of the rotating packing.

[0014] S3. As impurities are discharged from the rotating packing and fall onto the cleaning guide ring, gas enters through the inlet pipe, blowing the rotating fan blades to rotate, which in turn drives the rotating rod to rotate synchronously. This, in conjunction with the adjusting slider and control ring, causes the support rod to slide up and down intermittently, which in turn causes the cleaning guide ring to slide up and down intermittently, allowing the impurities on the cleaning guide ring to slide down onto the partition plate for collection.

[0015] This wet electronic chemical separation and purification device and method uses a drive motor to rotate the drive shaft, which in turn causes the rotating packing material to rotate during use. The solution flows from top to bottom, and the gas flows from bottom to top, reacting within the rotating packing material. This ensures that solid impurities precipitated from the solution adhere primarily to the upper side or outer ring of the rotating packing material. Therefore, when the cleaning brush scrapes off impurities, it does not need to penetrate deep into the rotating packing material, avoiding interference with the reaction within the packing material. This makes it difficult for impurities to adhere to the rotating packing material, extending the device's service life and maintaining stable internal pressure. On the other hand, when gas passes through the inlet pipe, it causes the rotating fan blades to rotate, which in turn causes the cleaning guide ring to slide up and down intermittently. This cleans impurities on the cleaning guide ring and collects them on a partition plate, promptly separating the impurities cleaned by the cleaning brush from the solution and preventing re-mixing.

[0016] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] In the above description of the present invention, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is conventionally placed during use. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element 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 present invention. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0023] This invention provides a technical solution: a wet electronic chemical separation and purification device.

[0024] Please see Figures 1 to 9 The system includes a protective outer shell 1, a drive structure 2 mounted on the lower side of the protective outer shell 1, an array of flow guiding structures 3 installed inside the protective outer shell 1, a rotating packing 4 corresponding to the flow guiding structures 3 mounted on the drive structure 2, a cleaning brush 5 installed inside the flow guiding structures 3, the rotating packing 4 rotating with the drive structure 2, and a partition plate 7 installed inside the protective outer shell 1. The drive structure 2 includes a support tower bottom 21 installed at the bottom of the protective shell 1, a drive motor 22 installed inside the support tower bottom 21, a drive shaft 23 installed on the output shaft of the drive motor 22, an array of rotating packing 4 installed on the drive shaft 23, and the rotating packing 4 slidingly engaging with the cleaning brush 5. The flow guiding structure 3 includes an array of isolation mounting tubes 31 mounted on the inner contour of the protective housing 1. A guide plate 32 is mounted on the isolation mounting tubes 31, and a liquid receiving component 33 is mounted on the upper side of the guide plate 32.

[0025] Using the above method: the drive motor 22 drives the drive shaft 23 to rotate, which in turn drives the rotating packing 4 to rotate. During the purification process of the solution in the rotating packing 4 under the influence of gas, the precipitated impurities, when they adhere to the inner wall of the rotating packing 4, are simultaneously scraped off by the cleaning brush 5 and affected by the centrifugal force generated when the rotating packing 4 rotates. Combined with the gas blowing, the impurities are difficult to adhere to the inner wall of the rotating packing 4, thus preventing blockage of the rotating packing 4. This extends the service life of the device, reduces disassembly and cleaning, and stabilizes the internal pressure of the device. On the other hand, the solution enters the rotating packing 4 from top to bottom and from the outside to the inside. The solution that enters first is preferentially affected by the upward gas. As a result, the precipitated impurities mostly adhere to the upper inner wall and the inner wall of the outer ring of the rotating packing 4. Therefore, the cleaning brush 5 only needs to scrape the corresponding positions without going deep into the rotating packing 4. While scraping out the impurities, it does not affect the reaction between the solution and the gas, thus enhancing efficiency.

[0026] Please see Figure 2 and Figure 3 The top of the protective housing 1 is equipped with an inlet pipe for inputting the solution and an outlet pipe for outputting gas.

[0027] A drain pipe 24 is installed on the lower side of the support tower bottom 21. The drain pipe 24 is connected to the upper end of the support tower bottom 21 and is connected to the liquid inlet pipe at the top of the protective shell 1. A truncated cone with an inclined surface is provided in the middle of the support tower bottom 21.

[0028] The above method is adopted: by installing the drive motor 22 inside the support tower bottom 21 to protect the drive motor 22, and designing the support tower bottom 21 into the shape of a central sloping frustum, the downward flowing solution can be better collected, which facilitates solution collection and increases the efficiency of the device.

[0029] Please see Figure 5 The liquid receiving component 33 is equipped with a guide ring 34 at its upper end. The upper end of the guide ring 34 has a sloping structure. The liquid receiving component 33 has a through hole, and the through hole on the liquid receiving component 33 corresponding to the cleaning brush 5 is closed.

[0030] A cleaning guide ring 35 is slidably connected inside the isolation installation tube 31. The upper end of the cleaning guide ring 35 is a slope, and the slope of the slope of the cleaning guide ring 35 is consistent with that of the corresponding guide ring 34.

[0031] The bottom diameter of the guide plate 32 is larger than the diameter of the isolation installation tube 31. There is a gap between the guide plate 32 and the protective shell 1. The diameters of the liquid receiving component 33, the guide ring 34 and the cleaning guide ring 35 are the same.

[0032] Using the above method: by setting up an isolation installation pipe 31 and a guide plate 32 in conjunction with a liquid receiving component 33 to fully enclose the rotating packing 4, the reaction between the solution and the gas and the cleaned impurities are separated, preventing the impurities from remixing with the solution.

[0033] Please see Figures 7 to 9 The protective housing 1 is equipped with a symmetrically distributed intermittent transmission structure 6. The intermittent transmission structure 6 includes symmetrically arrayed support plates 62 that are slidably connected to the inner contour of the protective housing 1. Connecting rods 61 are installed between the support plates 62. Limiting sliders 63 are installed on the side of each support plate 62 near the protective housing 1. The limiting sliders 63 are slidably connected to the protective housing 1. The protective housing 1 has grooves corresponding to the limiting sliders 63. The support plates 62 are fixedly installed to the lower end of the cleaning guide ring 35. The cleaning guide ring 35 is slidably engaged with the corresponding guide ring 34. An air intake pipe 64 is installed through the protective housing 1, which is distributed on the vehicle. A rotating fan blade 65 is rotatably connected inside the air intake pipe 64. A rotating rod 66 is installed on the upper end of the rotating fan blade 65. The rotating rod 66 is rotatably connected through the air intake pipe 64. A control ring 67 is installed on the rotating rod 66. A support rod 68 is slidably connected inside the rotating rod 66. An adjusting slider 69 that slidably cooperates with the control ring 67 is installed on the support rod 68.

[0034] A recessed groove is provided on the control ring 67, a tension spring is provided between the support rod 68 and the rotating rod 66, the support rod 68 is rotatably connected to the partition plate 7, and the support rod 68 is supported and cooperated with the support plate 62 on the lower side.

[0035] The above method is used as follows: gas enters through the air inlet pipe 64, which in turn blows the rotating fan blade 65 to rotate, causing the rotating rod 66 and the control ring 67 to rotate synchronously. Through the influence of the tension spring between the rotating rod 66 and the support rod 68, the adjusting slider 69 is brought into contact with the control ring 67. When the sliding groove of the control ring 67 is in contact with the adjusting slider 69, the support rod 68 slides downward, causing the support plate 62, which is supported by the support rod 68, to slide downward synchronously. This causes the cleaning guide ring 35 to slide synchronously, allowing impurities on the cleaning guide ring 35 to fall onto the partition plate 7 for collection. Through the continuous rotation of the control ring 67, the cleaning guide ring 35 slides up and down intermittently with the adjusting slider 69, cleaning the impurities on the cleaning guide ring 35 in a timely manner and preventing the possibility of impurities mixing with the solution again.

[0036] This invention also provides a method for separating and purifying wet electronic chemicals, comprising the following steps: S1. Drive shaft 23 is driven by drive motor 22 to rotate, which in turn causes rotating packing 4 to rotate synchronously with drive shaft 23. As the processing solution enters from the liquid inlet pipe at the top of protective shell 1, the processing gas enters from the air inlet pipe 64 and they converge in rotating packing 4 for processing. S2. During the processing of the solution, solid impurities will be generated and adhere to the rotating packing 4. Then, through the friction between the rotating packing 4 and the cleaning brush 5, the newly attached impurities are scraped off by the cleaning brush 5. Combined with the upward gas driving force and the centrifugal force generated by the rotation of the rotating packing 4, the impurities are discharged out of the rotating packing 4.

[0037] S3. As impurities are discharged from the rotating packing 4, they fall onto the cleaning guide ring 35. Gas enters through the air inlet pipe 64, blowing the rotating fan blade 65 to rotate, which drives the rotating rod 66 to rotate synchronously. This, in conjunction with the adjusting slider 69 and the control ring 67, causes the support rod 68 to slide up and down intermittently, which in turn causes the cleaning guide ring 35 to slide up and down intermittently, allowing the impurities on the cleaning guide ring 35 to slide down onto the partition plate 7 for collection.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
