Description

Technical Field

[0001] This invention relates to the field of deodorization and decolorization treatment technology for liquids, and particularly to a deodorization and decolorization device and process. Background Technology

[0002] In the context of the circular economy, many chemical companies recycle solvents, lubricants, and other materials. These materials are often contaminated after use, becoming darker in color and emitting a pungent odor. They must undergo deodorization and decolorization treatment before they can be reused. Current technologies typically involve adding decolorizing and deodorizing agents to the raw solution and stirring the mixture to ensure a thorough reaction between the raw solution and the agents, thus achieving decolorization and deodorization of the raw solution.

[0003] To enhance the rate of chemical reactions and efficiently remove odors and pigments, existing technologies typically place the stock solution, decolorizing agent, and deodorizing agent into a high-gravity rotating bed for reaction. The high-gravity rotating bed is an innovative piece of chemical process equipment that generates powerful centrifugal force through high-speed rotation, thereby greatly enhancing mass transfer, heat transfer, and reaction processes.

[0004] A high-gravity rotating bed consists of a shell, a baffle rotor, and a liquid distributor. The baffle rotor typically comprises concentric, interlocking moving and stationary baffle rings. The moving baffle rings are connected to the main shaft and rotate at high speed with the rotor, while the stationary baffle rings are fixed to the shell and remain stationary. During operation, the liquid enters the inner edge of the rotor and is "captured" by the high-speed rotating moving baffle rings, then accelerated and thrown outwards. After being thrown out, the liquid impacts the stationary baffle rings and is violently broken up. Subsequently, the liquid on the stationary baffle rings is again captured, accelerated, and thrown out by the next stage of rotating moving baffle rings. This process applies extreme shear force to the liquid and disperses it into micron or nanometer-sized particles, thereby achieving uniform mixing of the stock solution and the reaction reagents.

[0005] For example, the composite rotor hypergravity rotating bed disclosed in patent CN106178573B includes a shell, a stationary disk, a liquid inlet pipe located in the center above the stationary disk, and capillary outlet holes on the wall of the liquid inlet pipe located inside the shell. The composite rotor enters the shell from the bottom upwards and is coaxially arranged with the stationary disk. The composite rotor includes concentrically distributed dynamic baffles, and the stationary disk has concentrically distributed static baffles. The dynamic baffles and static baffles are nested together. The innermost layer of the composite rotor has several corrugated discs evenly distributed from top to bottom. The corrugated discs have through holes and are fixed to the outside of the liquid inlet pipe. A liquid outlet is provided at the bottom of the shell, a gas inlet is provided on the side wall of the shell, and a gas outlet is provided on the outside of the liquid inlet pipe above the stationary disk.

[0006] Because the reaction between the stock solution and the deodorizing and decolorizing agents produces flocculent matter, impurities will adhere to the surfaces of the static and dynamic baffles after long-term use. In existing technology, for general impurities, adding cleaning agent and water to the equipment allows for automatic cleaning via high-speed rotor rotation. However, for impurities with strong adhesion, the rotor needs to be disassembled for manual brushing. This cleaning method involves disassembling and reassembling the equipment, which is cumbersome, time-consuming, labor-intensive, and inefficient due to high labor costs. Summary of the Invention

[0007] This invention provides a deodorizing and decolorizing device to solve the technical problem that the cleaning process of the high-gravity rotating bed used to accelerate the deodorizing and decolorizing reaction is cumbersome and has low cleaning efficiency.

[0008] The present invention also provides a deodorization and decolorization process. Using this process to deodorize and decolorize the original solution can improve the reaction rate and also improve the cleaning efficiency of the reaction equipment after the reaction.

[0009] To solve the above problems, the present invention provides a deodorizing and decolorizing device with the following technical solution:

[0010] A deodorizing and decolorizing device includes a high-gravity rotating bed. The high-gravity rotating bed includes a shell. Inside the shell, there is a fixed plate and a moving plate. The bottom of the fixed plate is provided with a plurality of spaced and nested static baffles. The top of the moving plate is provided with a plurality of spaced and nested moving baffles. The plurality of moving baffles and the plurality of static baffles are arranged alternately from the inside to the outside.

[0011] Each stationary baffle ring with a moving baffle ring on its inner side has an inner scraper ring in the shape of a ring on the inner side of the end away from the fixed plate. The inner scraper ring is pressed against the outer wall of the corresponding moving baffle ring. Each stationary baffle ring with a moving baffle ring on its outer side has an outer scraper ring in the shape of a ring on the outer side of the end away from the fixed plate. The outer scraper ring is pressed against the inner wall of the corresponding moving baffle ring.

[0012] Each of the moving baffles with a static baffle on the outer side has an outer scraper in the shape of a ring on the outer side of the end away from the moving disk. The outer scraper is pressed against the inner wall of the corresponding static baffle. Each of the moving baffles with a static baffle on the inner side has an inner scraper in the shape of a ring on the inner side of the end away from the moving disk. The inner scraper is pressed against the outer wall of the corresponding static baffle.

[0013] An annular sealing body is installed on the inner wall of the outer shell. The outer shell is also equipped with a moving drive mechanism that drives the fixed plate to move up and down. During operation, the sealing body is located below the fixed plate, forming an annular gap between the two plates to allow liquid to pass through. During cleaning, the fixed plate moves down into the sealing body and slides up and down within the sealing body, adhering to the inner wall of the sealing body. At this time, a cleaning chamber is formed between the outer shell, the moving plate, the fixed plate, and the sealing body.

[0014] Using the above technical solution, in operation, the fixed plate is located above the sealing body, forming an annular gap between it and the sealing body to allow the reacted liquid to drain. When cleaning is required, the moving drive mechanism drives the fixed plate to move inside the sealing body, injects cleaning fluid into the cleaning chamber, and then starts the moving drive mechanism to drive the fixed plate to move up and down reciprocally inside the sealing body. This allows the inner scraper one and outer scraper one to scrape away impurities on the outer wall of the moving baffle ring, while the inner scraper two and outer scraper two scrape away impurities on the outer wall of the stationary baffle ring. Deep cleaning of the moving and stationary baffle rings can be achieved without removing them, making the cleaning process more convenient and efficient.

[0015] By incorporating a sealing element, the fixed disc, during its reciprocating movement, interacts with the moving disc, the outer casing, and the sealing element to form a cleaning chamber. This chamber stores cleaning fluid. During the scraping process, the moving and stationary baffles come into contact with the cleaning fluid, making it easier for impurities to detach from the baffles, resulting in better cleaning. Furthermore, injecting cleaning fluid only into the cleaning chamber is sufficient to clean each baffle, eliminating the need to fill the entire inner cavity of the outer casing, thus reducing cleaning fluid consumption and lowering cleaning costs.

[0016] Furthermore, in each of the moving and stationary baffles, the outermost baffle is equipped with an auxiliary scraper. The auxiliary scraper is connected to the corresponding moving or stationary disc via a connecting rod, so that when the stationary disc moves up and down, the auxiliary scraper can scrape off impurities on the outer wall of the outermost baffle.

[0017] By adopting the above technical solution, impurities on the outermost baffle ring can also be scraped off.

[0018] Furthermore, a filter screen is also provided inside the outer casing, located at the bottom of the sealing body.

[0019] Using the above technical solution, flocculent matter will be generated after the solution reaction. After being added to a filter screen, the solution after the reaction is filtered and then discharged, resulting in a purer liquid that is easier to process in the next step.

[0020] Furthermore, the sealing body is hollow inside, and an annular impurity inlet is provided at the bottom of the inner wall of the sealing body. A cleaning component is rotatably installed above the filter screen. The cleaning component includes an arc-shaped cleaning plate, the outer end of which extends to the impurity inlet. When the cleaning component rotates, the outwardly convex arc-shaped surface of the cleaning plate faces the impurities on the surface of the filter screen. The cleaning plate scrapes off the impurities on the surface of the filter screen and guides them to the impurity inlet.

[0021] Using the above technical solution, the sealing body is designed as a hollow structure. When the cleaning component rotates, the cleaning plate can scrape off the impurities on the surface of the filter screen and guide the impurities to the impurity inlet. The impurities enter the inner cavity of the sealing body through the impurity inlet. The impurities leave the surface of the filter screen and are temporarily stored in the inner cavity of the sealing body, thus preventing the accumulation of impurities on the surface of the filter screen from affecting the filtration effect of the filter screen. The sealing body can not only seal the outer edge of the fixed plate, but also store impurities. It is a multi-purpose device that can save space.

[0022] Furthermore, a conveying auger is rotatably installed inside the sealing body, and an impurity outlet is provided on the outer shell. The impurity outlet is located at the top of the sealing body cavity. When the conveying auger rotates, it can transport impurities that have entered the sealing body cavity from the impurity inlet upward to the impurity outlet.

[0023] By adopting the above technical solution, a conveying auger is added to the inner cavity of the sealing body. When the conveying auger rotates, it can transport the impurities that have entered the inner cavity of the sealing body to the impurity outlet, so that the impurities can be discharged and the impurities can be avoided from accumulating in the inner cavity of the sealing body for a long time, thereby achieving the cleaning of the inner cavity of the sealing body.

[0024] Furthermore, the outer end of the cleaning plate is connected to the conveying auger, and the cleaning component can drive the conveying auger to rotate synchronously when it rotates.

[0025] By adopting the above technical solution, the outer end of the cleaning plate is connected to the conveying auger. When the cleaning part rotates, it can drive the conveying auger to rotate synchronously, eliminating the need to drive the conveying auger to rotate separately. This simplifies the structure and saves power costs.

[0026] Furthermore, each fixed plate has a sludge discharge hole at a position corresponding to the area between each pair of static deflectors. A baffle is provided at the bottom of the fixed plate, and an elastic element is connected between the baffle and the fixed plate. The elastic element presses the baffle against the fixed plate to block each sludge discharge hole. A limiting element is provided on the inner side of the sealing body. The limiting element stops the outer end of the fixed plate vertically and is offset vertically from the outer end of the baffle. The drive output end of the moving drive mechanism is connected to the baffle. After the fixed plate moves downward and contacts the limiting element, the baffle continues to move downward and separates from the fixed plate, exposing the sludge discharge holes.

[0027] Using the above technical solution, the fixed plate is provided with a discharge hole, and a baffle is elastically connected to the bottom of the fixed plate. The sealing body is provided with a limiting component. The baffle can move up and down synchronously with the fixed plate through the elastic component. When the fixed plate moves to the point where it is blocked by the limiting component, the fixed plate will no longer move downward. The baffle is driven by the moving drive mechanism to continue to move downward, so that the baffle is separated from the fixed plate, the discharge hole is exposed, the liquid in the cleaning chamber can be discharged downward, and the impurities falling between the two adjacent static baffles can also be discharged downward.

[0028] Furthermore, a liquid distributor is located inside the innermost dynamic baffle ring. The top of the liquid distributor is connected to an inlet pipe and a reagent pipe, and the bottom of the shell is connected to an outlet pipe, which communicates with the space inside the shell located below the filter screen.

[0029] Furthermore, the supergravity rotating bed is provided in two sets, with the liquid outlet pipe in one set of supergravity rotating beds connected to the liquid inlet pipe in the other set of supergravity rotating beds. The reagent tube in one set of supergravity rotating beds is used for inputting deodorizing reagent, and the reagent tube in the other set of supergravity rotating beds is used for inputting decolorizing reagent.

[0030] Using the above technical solution, two sets of high-gravity rotating beds are set up. One set of high-gravity rotating beds is used to deodorize the original liquid, and the other set is used to decolorize the original liquid. The deodorization and decolorization are carried out separately to avoid the deodorization reagent and the decolorization reagent from mixing and affecting the chemical reaction with the original liquid.

[0031] The beneficial effects of the odor removal and decolorization device provided by this invention are as follows: By configuring the fixed plate as a structure capable of vertical movement and installing scrapers at the ends of the moving and stationary baffles, the scrapers can remove impurities from the surfaces of the moving and stationary baffles as the fixed plate moves up and down, making the cleaning of the moving and stationary baffles more convenient and efficient. By incorporating a sealing body, the fixed plate can move up and down within the sealing body, forming a cleaning chamber for storing cleaning fluid between the fixed plate, the sealing body, the outer shell, and the moving plate during this movement. During the scraping of impurities, each baffle can come into contact with the cleaning fluid, improving the cleaning effect. By designing the sealing body as a hollow structure, the impurities filtered by the filter screen are collected within the inner cavity of the sealing body, effectively utilizing the internal space of the sealing body, saving space, and making the equipment's structural design simpler and smaller in size.

[0032] The present invention also provides a deodorization and decolorization process, which is implemented using the above-mentioned deodorization and decolorization device, and the process includes the following steps:

[0033] S1. Guide the original liquid and treatment reagents to the innermost moving baffle ring, drive the moving disk to rotate, and the liquid will be thrown to the outside through each moving baffle ring and each stationary baffle ring in sequence, and fall onto the filter screen through the annular interval and be discharged after filtration.

[0034] S2. After the original solution is treated, the moving drive mechanism drives the fixed plate to move down into the sealing body, injects cleaning fluid into the cleaning chamber, and then drives the moving drive mechanism to move the fixed plate up and down inside the sealing body. The inner scraper one and the outer scraper one scrape off the impurities on the outer wall of the moving baffle ring, and the inner scraper two and the outer scraper two scrape off the impurities on the outer wall of the static baffle ring.

[0035] The beneficial effects of the deodorizing and decolorizing process provided by this invention are: it can fully mix and react the original solution with the deodorizing agent and the decolorizing agent, thereby improving the reaction efficiency; and it can also automatically and efficiently clean the equipment after the reaction is completed.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0048] The following is one embodiment of a deodorizing and decolorizing device provided by the present invention:

[0049] like Figures 1-9 As shown, a deodorizing and decolorizing device includes a high-gravity rotating bed, a waste discharge pipe, and a waste collection box 2.

[0050] like Figure 1 , Figure 2 , Figure 3 As shown, the supergravity rotating bed includes a shell, a moving disk 11, a moving baffle ring 12, a fixed disk 21, a stationary baffle ring 13, a liquid distributor, a sealing body 19, a filter screen 27, a moving drive mechanism, a rotating drive mechanism one, and a rotating drive mechanism two.

[0051] The outer shell includes a cylindrical body 1, a top sealing plate 8, and a bottom sealing plate 23. The top sealing plate 8 and the bottom sealing plate 23 are arranged vertically at intervals inside the cylindrical body 1. The space between the top sealing plate 8, the bottom sealing plate 23, and the cylindrical body 1 forms the working chamber inside the outer shell. Two limiting ring plates 10 are also provided on the inner wall of the cylindrical body 1, arranged vertically at intervals, and the two limiting ring plates 10 are located inside the working chamber.

[0052] The cylindrical body 1 is also provided with a support plate 24, which is located below the bottom sealing plate 23 and is spaced apart from the bottom sealing plate 23.

[0053] The moving plate 11 is sandwiched between two limiting ring plates 10. The two limiting ring plates 10 limit the vertical position of the moving plate 11, while also allowing the moving plate 11 to rotate around its own axis.

[0054] like Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, the moving plate 11 has a through hole running vertically through the middle, and a connecting sleeve 30 coaxial with the through hole is connected to the top.

[0055] Multiple moving baffle rings 12 are provided. The moving baffle rings 12 are existing structures in the prior art. Specifically, they are sleeve structures with many perforations distributed on the side wall. The perforations are not shown in the figure. Multiple moving baffle rings 12 are connected to the bottom of the moving disk 11 and are coaxially spaced and nested.

[0056] The fixed plate 21 is located below the moving plate 11 and is coaxial with the moving plate 11. The fixed plate 21 has multiple vertically penetrating drainage holes 211.

[0057] Multiple static deflector rings 13 are provided. The static deflector rings 13 are existing structures in the prior art. Specifically, they are sleeve structures with many perforations distributed on the side wall. The perforations are not shown in the figure. Multiple static deflector rings 13 are connected to the top of the fixed plate 21 and are coaxially spaced and nested.

[0058] Each of the regions in the aforementioned fixed plate 21 corresponding to the area between each pair of adjacent static baffle rings 13 is provided with a debris discharge hole 211.

[0059] Multiple stationary baffles 13 are respectively installed in the intervals between multiple moving baffles 12, so that the moving baffles 12 and the stationary baffles 13 are arranged alternately, with the innermost baffle being the moving baffle 12 and the outermost baffle being the stationary baffle 13.

[0060] Each of the aforementioned moving deflector rings 12 has an outer ring-shaped scraper 45 connected to its outer side by two connecting rods 44. The outer side wall of the outer scraper 45 is in contact with the inner side wall of the adjacent static deflector ring 13, so that the outer scraper 45 is pressed onto the adjacent static deflector ring 13.

[0061] Except for the innermost moving baffle ring 12, each moving baffle ring 12 has an inner scraper 2 34 connected to its inner side by two connecting rods 44. The inner wall of the inner scraper 2 34 is in contact with the outer wall of the adjacent inner stationary baffle ring 13, so that the inner scraper 2 34 is pressed on the adjacent inner stationary baffle ring 13.

[0062] Each of the aforementioned static deflector rings 13 has an inner scraper 33 connected to its inner side by two connecting rods 44. The inner wall of the inner scraper 33 is in contact with the outer wall of the adjacent moving deflector ring 12, so that the inner scraper 33 is pressed on the adjacent moving deflector ring 12.

[0063] Except for the outermost static baffle ring 13, each static baffle ring 13 is connected to an annular outer scraper 45 by two connecting rods 44. The outer side wall of the outer scraper 45 is in contact with the inner side wall of the adjacent dynamic baffle ring 12, so that the outer scraper 45 is pressed on the adjacent dynamic baffle ring 12.

[0064] To clean the outermost stationary baffle ring 13 and the innermost moving baffle ring 12, an annular auxiliary scraper 35 is connected to the moving plate 11 via a connecting rod 39. The auxiliary scraper 35 is fitted onto the outermost stationary baffle ring 13. An annular auxiliary scraper 36 is connected to the fixed plate 21 via a connecting rod 37. The auxiliary scraper 36 is located inside the innermost moving baffle ring 12, and its outermost wall is in contact with the innermost moving baffle ring 12.

[0065] The bottom of the fixed plate 21 is provided with a baffle 22, which is coaxial with the fixed plate 21. The outer diameter of the baffle 22 is smaller than that of the fixed plate 21, and the baffle 22 can cover all the impurity discharge holes 211 on the fixed plate 21.

[0066] like Figure 5 , Figure 6 As shown, three guide sleeves 32, evenly distributed along the circumference of the baffle 22, are vertically connected to the bottom of the baffle 22, and the bottom ends of the guide sleeves 32 are closed. Three insert rods 40 are vertically connected to the bottom of the fixed plate 21, and the three insert rods 40 are respectively inserted into the three guide sleeves 32. The diameter of the insert rods 40 is smaller than the inner diameter of the guide sleeves 32. A circular insert plate 42 is vertically connected to the bottom end of the insert rods 40. The outer diameter of the insert plate 42 is equal to the inner diameter of the guide sleeve 32. The insert plate 42 is fitted and inserted into the guide sleeve 32. An elastic element 41 capable of extending and retracting in the vertical direction is connected between the insert plate 42 and the bottom of the guide sleeve 32. The elastic element 41 connects the fixed plate 21 to the baffle 22, and when the baffle 22 is driven to move up and down, it can drive the fixed plate 21 to move up and down as well.

[0067] The liquid distributor is located inside the innermost moving baffle ring 12. The liquid distributor includes a liquid storage tank 14, which is cylindrical. The top of the side wall of the liquid storage tank 14 is provided with a ring of evenly arranged liquid outlet holes 141. A ring of water guide plates 31 is connected to the outer side wall of the liquid storage tank 14. The water guide plates 31 are lower than the liquid outlet holes 141. There is a small gap between the outer edge of the water guide plates 31 and the inner side wall of the innermost moving baffle ring 12. This small gap allows the liquid overflowing from the liquid outlet holes 141 onto the water guide plates 31 to contact the inner wall of the moving baffle ring 12 when it flows to the edge of the water guide plates 31, and to fall evenly onto the inner side wall of the moving baffle ring 12.

[0068] The top of the liquid storage tank 14 is also connected to an inlet pipe 6 and a reagent tube 7. The top end of the inlet pipe 6 passes through the moving plate 11, the connecting sleeve 30 and the top sealing plate 8 and extends to the top of the outer shell. The inlet pipe 6 and the top sealing plate 8 are fixed relative to each other. The reagent tube 7 is connected to the inlet pipe 6 perpendicularly and communicates with the inner cavity of the inlet pipe 6.

[0069] The sealing body 19 is annular and is coaxially mounted on the inner wall of the cylindrical body 1, located within the working chamber. The inner diameter of the sealing body 19 is the same as the outer diameter of the fixed plate 21. When the fixed plate 21 and the moving plate 11 are in working condition, the sealing body 19 is located below the fixed plate 21. At this time, there is an annular gap between the sealing body 19 and the fixed plate 21, and the height of the annular gap is not greater than the height of the inner scraper 33 and the outer scraper 43.

[0070] The sealing body 19 is hollow, forming a temporary storage cavity for storing impurities. A ring-shaped impurity inlet 191 is formed on the bottom inner wall of the sealing body 19, communicating with the temporary storage cavity. An impurity outlet 101, communicating with the temporary storage cavity, is provided on the side wall of the cylindrical body 1. The impurity outlet 101 corresponds to the area at the top of the temporary storage cavity. Figure 3 , Figure 9 As shown, a conveying auger 20 is rotatably installed inside the temporary storage cavity. A ring-shaped rotating plate 26 is connected to both the top and bottom ends of the conveying auger 20. The two rotating plates 26 are rotatably installed inside the temporary storage cavity and are in contact with the top and bottom side walls of the temporary storage cavity, respectively.

[0071] The inner wall of the sealing body 19 is also connected to a limiting member 25. The limiting member 25 is a circular plate. The inner diameter of the limiting member 25 is smaller than the outer diameter of the fixed plate 21 and larger than the outer diameter of the baffle 22.

[0072] like Figure 3 , Figure 8As shown, the filter screen 27 is installed at the bottom of the sealing body 19, and the top surface of the filter screen 27 is slightly higher than the impurity inlet 191. A cleaning component is rotatably installed in the middle of the filter screen 27. The cleaning component includes a rotating sleeve 29 and a cleaning plate 28. The rotating sleeve 29 is rotatably inserted through the middle of the filter screen 27 and is fixed relative to the filter screen 27 in the vertical direction. There are three cleaning plates 28, all connected to the outer wall of the rotating sleeve 29 and evenly distributed in the circumferential direction of the rotating sleeve 29.

[0073] The bottom ends of the three cleaning plates 28 are all in contact with the filter screen 27. The cleaning plates 28 are arc-shaped, and their outer ends are all connected to the rotating plate 26 located at the bottom. The bottom end of the rotating sleeve 29 extends through the bottom sealing plate 23 to the space between the bottom sealing plate 23 and the support plate 24. When the rotating sleeve 29 rotates, it drives the cleaning plates 28 to rotate, and the cleaning plates 28 drive the conveying auger 20 to rotate through the rotating plate 26. When the cleaning plates 28 rotate, the protruding arc-shaped surface of the cleaning plates 28 faces the impurities on the surface of the filter screen 27 and guides the impurities to move towards the impurity inlet 191. At the same time, when the conveying auger 20 rotates, it can carry the impurities entering the temporary storage chamber upward, so that the impurities are discharged from the impurity outlet 101.

[0074] A solution storage cavity 38 is formed between the filter sieve 27 and the bottom sealing plate 23 for temporarily storing the solution after the reaction. A drain hole communicating with the solution storage cavity 38 is provided on the side wall of the cylindrical body 1, and an outlet pipe 9 is connected to the outside of the drain hole.

[0075] like Figure 3 As shown, the moving drive mechanism includes a lifting cylinder 15, which is located inside the cylindrical body 1 and below the support plate 24. The lifting cylinder 15 has a drive output end capable of moving up and down, and the drive output end of the lifting cylinder 15 passes through the middle of the bottom sealing plate 23 and the filter screen 27 and is connected to the baffle 22. The lifting cylinder 15 can drive the baffle 22 to move up and down, thereby driving the fixed plate 21 and the static baffle ring 13 connected to the fixed plate 21 to move up and down. When the fixed plate 21 is in the working state, the lifting cylinder 15 keeps the fixed plate 21 stationary at a top limit position. When the fixed plate 21 is in this position, it is higher than the sealing body 19, and an annular gap is formed between the fixed plate 21 and the sealing body 19. When the equipment needs to be cleaned, the lifting cylinder 15 drives the baffle 22 to move the fixed plate 21 down into the sealing body 19. Then, it drives the fixed plate 21 to move up and down inside the sealing body 19, so that each scraper scrapes off the impurities on the outer wall of each baffle ring. At this time, a cleaning chamber is formed between the fixed plate 21, the moving plate 11, the sealing body 19 and the outer shell.

The impurity discharge pipe includes two inclined impurity discharge pipe sections 3 and an impurity outlet pipe section 4 connected to the bottom of the two impurity discharge pipe sections 3.

[0081] The present invention provides scrapers at the ends of the moving baffle ring 12 and the stationary baffle ring 13 and sets the fixed plate 21 to be able to move up and down. When the fixed plate 21 is driven to move up and down, it can drive the scraper to move on the surface of the baffle ring to scrape off the impurities on the surface of the baffle ring, making the cleaning process simpler and more efficient.

[0082] The present invention also provides a deodorization and decolorization process, which is implemented by using the above-mentioned deodorization and decolorization device, and includes the following steps:

[0083] S1. The original solution to be treated and the decolorizing reagent are injected into the inlet pipe 6 and reagent pipe 7 of the high-gravity rotating bed for decolorization, respectively. The mixed solution flows from the distributor to the inner wall of the innermost moving baffle ring 12. The drive motor 1 5 and drive motor 2 16 are started. The moving plate 11 rotates the moving baffle ring 12, so that the mixed solution is thrown out through each moving baffle ring 12 and the stationary baffle ring 13, and falls from the annular interval to the filter screen 27. After being filtered by the filter screen 27, it is discharged into the solution storage chamber 38. The cleaning plate 28 rotates to scrape off the impurities on the filter screen 27 and pushes the impurities to the impurity inlet 191. The conveying auger 20 conveys the impurities upward to the impurity outlet 101, and sends them to the impurity collection box 2 through the impurity discharge pipe.

[0084] S2. The pump body pumps the decolorized solution from the solution storage chamber 38 of the centrifugal rotating bed for decolorization to the inlet pipe 6 of the centrifugal rotating bed for deodorization. At the same time, deodorizing reagent is injected into the reagent tube 7 of the deodorizing centrifugal rotating bed. The subsequent steps in step S1 above are repeated in the centrifugal rotating bed for deodorization. Finally, the solution after the reaction is discharged from the outlet pipe 9 of the centrifugal rotating bed for deodorization and is collected.

[0085] S3. Start the lifting cylinder 15 to drive the baffle 22 to move the fixed plate 21 downward. After the fixed plate 21 moves into the inside of the sealing body 19, stop driving the fixed plate 21 downward. Inject cleaning fluid into the cleaning chamber. Start the lifting cylinder 15 again to drive the baffle 22 to move the fixed plate 21 up and down reciprocally inside the sealing body 19. The outer scraper 43, the inner scraper 33, and the auxiliary scraper 36 scrape the impurities on the inner and outer surfaces of the moving baffle ring 12. The outer scraper 45 and the inner scraper 36 scrape the impurities on the inner and outer surfaces of the moving baffle ring 12. The second 34 and the auxiliary scraper 35 scrape off the impurities on the inner and outer surfaces of the stationary baffle ring 13. After the scraping time is set, the lifting cylinder 15 drives the baffle 22 to move downward to below the limiting member 25. The fixed plate 21 is blocked by the limiting member 25 and separated from the baffle 22, so that the impurity discharge hole 211 on the fixed plate 21 is exposed. The scraped impurities mixed with the cleaning liquid are discharged from the impurity discharge hole 211. At this time, clean water is continuously injected into the cleaning chamber to clean the cleaning chamber and flush out the impurities.
