Technical Field

[0001] The invention relates to the technical field of supergravity reactors, in particular to a device for recovering organic matter in waste liquid by supergravity-decompression stripping combination. Background Art

[0002] A supergravity reactor is a device that uses a centrifugal field to enhance mass transfer and reaction processes. When treating liquids containing organic matter, the supergravity reactor can effectively promote the recovery of organic matter. The application of supergravity reactors in the synthesis of nanomaterials, degradation of organic matter, and catalytic reactions shows that it can achieve efficient mass transfer and reaction processes in multiphase systems.

[0003] For example, a gas-liquid countercurrent type ultra-gravity rotating packed bed and method with internal circulation, with application number 202310261856.3, relates to the field of industrial reactor technology, and includes a first packing layer, an inner circle having a first cavity and a spray pipe for spraying solution introduced into the inner circle; a second packing layer, adjacently arranged below the first packing layer and rotating synchronously therewith, the inner circle having a second cavity; a cavity, covering the outer periphery of the first packing layer and the second packing layer, forming a liquid storage tank at the bottom, after the solution passing through the first packing layer enters the liquid storage tank, it enters the second packing layer through the two cavities to form an internal circulation; the cavity is provided with a gas inlet, and the gas is discharged from the cavity after countercurrent contact with the solution in the first packing layer and the second packing layer.

[0004] The above technical solution has some problems during use. This technical solution is not easy to clear when blockage occurs, and the liquids produced after the two reactions will mix, resulting in reduced reaction efficiency. The interior is also not easy to clean, and long-term use will cause internal blockage or even make it unusable.

[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention sets a cleaning component. During operation, the push rod continues to push the inclined platform to slide the corresponding dredging part rod, and inserts the dredging part into the corresponding through hole to dredge the blocked through hole. At the same time, the dredging part blocks a part of the liquid outlet of the nozzle. At this time, the position of the push rod that does not correspond to the through hole remains unchanged, so that the internal pressure of the corresponding nozzle increases, and the dredging effect is also achieved, thereby achieving the purpose of dredging when blockage occurs.

[0019] 2. The present invention solves the problem of liquid mixing after two reactions by arranging an upper centrifugal reaction component, a lower centrifugal reaction component, a liquid extraction component and a secondary reaction liquid tank. During the operation, the waste liquid is sprayed out through a nozzle and enters the inner side of the upper packing layer. At this time, the waste liquid is segmented and crushed by the packing layer, and then contacts with the gas to produce a reaction. The reacted liquid flows to the bottom of the reactor shell, and then the liquid is transported to the inner side of the lower packing layer through the liquid extraction component, and a secondary supergravity reaction is carried out through the lower packing layer. The liquid passing through the lower packing layer enters the secondary reaction liquid tank and is discharged through the secondary drain pipe. In this process, the waste liquid completes two supergravity reactions, prolongs the reaction time of the gas and the liquid, and prevents the liquids of the two reactions from contacting each other, thereby improving the reaction efficiency.

[0020] 3. The present invention solves the problem of inconvenient internal cleaning by providing a particle collection component. During operation, the guide plate rotates rapidly, and the flip plate is affected by centrifugal force to block the discharge gap. At the same time, the reset spring is compressed, and the upper filler layer rotates so that the impurities are guided by the scraper to the collection tank and temporarily stored. When the work is completed, the guide plate speed decreases, the centrifugal force on the flip plate is reduced, and the reset spring pushes the flip plate out of the discharge gap. At this time, the impurities in the collection tank are discharged through the discharge gap to prevent the impurities from clogging the filler layer, effectively solving the problem of internal blockage caused by long-term use.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1, the present invention provides as follows Figure 1-Figure 12The device for recovering organic matter in waste liquid by super gravity-decompression stripping combination shown in the figure comprises a reactor shell 1, a drive shaft 2 and a drive motor 3, the drive motor 3 is electrically connected with a controller and a power supply, the drive shaft 2 is rotatably connected in the reactor shell 1, the drive shaft 2 is coaxial with the reactor shell 1, the upper end of the drive shaft 2 penetrates the reactor shell 1, and the penetration position is a rotation seal; the lower end of the reactor shell 1 is fixedly connected with a plurality of legs, which is convenient for fixing the reactor position, and is fixedly connected with the output shaft of the drive motor 3, and also comprises: a liquid distribution component 4, which is placed on the outside of the drive shaft 2 and is fixedly connected to the reactor shell 1, and is used to input waste liquid and make the waste liquid evenly distributed. A cleaning component 5, which is placed in the liquid distribution component 4, is used to dredge and clean the liquid distribution component 4. An upper centrifugal reaction component 6, which is fixedly sleeved on the outside of the drive shaft 2, and the liquid distribution component 4 is placed on the inner side of the upper centrifugal reaction component 6. A lower centrifugal reaction component 7, which is fixedly sleeved on the outside of the drive shaft 2 and is placed at the lower end of the upper centrifugal separation component, and the upper centrifugal component and the lower centrifugal component are both used to generate centrifugal force for treating waste liquid. The secondary reaction liquid tank 8 is fixedly connected to the reactor housing 1 and is used to receive the liquid product produced by the lower centrifugal reaction component 7. It has a truncated cone structure that is not open upward. The liquid product produced by the upper centrifugal reaction component 6 will enter the bottom of the reactor housing 1. The liquid products of the upper centrifugal reaction component 6 and the lower centrifugal reaction component 7 are separated to avoid the problem of low reaction efficiency caused by the mixing of the liquids produced by the two reactions. The liquid extraction component 9 is slidably mounted on the outside of the drive shaft 2 and is sealed and slidably connected to the secondary reaction liquid tank 8. The liquid extraction component 9 is placed on the inner side of the lower centrifugal reaction component 7 to transport the liquid produced by the upper centrifugal reaction component 6 to the lower centrifugal reaction component 7, so that the liquid is fully mixed with the gas, and the contact reaction time between the liquid and the gas is extended to improve the reaction efficiency.

[0036] Specifically, the liquid distribution component 4 includes an annular liquid inlet chamber 401, which is rotatably mounted on the outside of the driving shaft 2, and the annular liquid inlet chamber 401 is a hollow structure. The liquid inlet pipe 402 is connected to the upper end of the annular liquid inlet chamber 401 and penetrates the upper end of the reactor shell 1. The liquid inlet pipe 402 defines the position of the annular liquid inlet chamber 401 and restricts the annular liquid inlet chamber 401 from rotating with the driving shaft 2. The end of the liquid inlet pipe 402 is connected to the pressure sensor and the infusion pump. The pressure sensor and the infusion pump are both existing technologies and will not be described in detail here. They are not shown in the figure. The infusion pump transports the waste liquid to the annular liquid inlet chamber 401 through the liquid inlet pipe 402. The liquid distributor 403 is fixedly connected to the middle part of the annular liquid inlet chamber 401 and is connected to the annular liquid inlet chamber 401. The liquid distributor 403 is provided in multiple numbers and is evenly distributed along the circumference of the driving shaft 2. The nozzle 404 is fixedly connected to the outer side of the liquid dispensing tube 403 and is communicated with the liquid dispensing tube 403. There are multiple nozzles 404, which are evenly distributed along the axial direction of the liquid dispensing tube 403. The outlet of each nozzle 404 is located at an end away from the driving shaft 2. During operation, waste liquid enters the multiple nozzles 404 through the liquid dispensing tube 403, and the waste liquid is evenly sprayed out of the annular liquid inlet cavity 401 by the nozzles 404.

[0037] More specifically, the liquid extraction assembly 9 includes a guide sleeve 901, which is fixedly connected to the bottom of the reactor housing 1. The lower end of the guide sleeve 901 is provided with a plurality of notches, so that the liquid generated by the upper centrifugal reaction assembly 6 can enter the inner side of the guide sleeve 901. The liquid extraction pipe 902 is slidably sleeved on the outer side of the driving shaft 2, and the lower end of the liquid extraction pipe 902 is placed on the inner side of the guide sleeve 901. The liquid extraction pipe 902 is sealed and slidably connected to the guide sleeve 901, and the upper end of the liquid extraction pipe 902 is rotatably connected to two symmetrically arranged sealing cover plates 903.

[0038] It should be noted that both the liquid lifting tube 902 and the guide sleeve 901 are elliptical structures. Due to the elliptical design, the guide sleeve 901 can directly limit the moving direction of the liquid lifting tube 902, so that the liquid lifting tube 902 can only slide in the vertical direction and will not rotate. In addition, the elliptical design also reserves an installation position for the sealing cover plate 903.

[0039] It should also be pointed out that the rotating shaft of the sealing cover 903 is set in an upper position so that it can only flip upward. During operation, the liquid lifting tube 902 slides upward. Due to the influence of inertia, the sealing cover 903 fits on the upper end of the liquid lifting tube 902, so that the upper end of the liquid lifting tube 902 is closed. At the same time, the liquid lifting tube 902 moves upward to attract the liquid inside the guide sleeve 901, and then the liquid lifting tube 902 is rapidly lowered. Due to the influence of inertia, the liquid in the liquid lifting tube 902 flows upward. At the same time, the sealing cover 903 is also opened due to inertia, so that the liquid in the liquid lifting tube 902 reaches the upper end of the liquid lifting tube 902, and then the liquid lifting tube 902 is slid upward again to extract the liquid inside the guide sleeve 901. In the process of the liquid lifting tube 902 floating up and down rapidly, the liquid inside the guide sleeve 901 is transported to the top of the liquid lifting tube 902.

[0040] The liquid extraction component 9 also includes a screw groove sleeve 904, which is fixedly connected to the outside of the driving shaft 2. A driving groove 905 is provided on the outside of the screw groove sleeve 904. The driving groove 905 is divided into an ascending section 9051 and a descending section 9052. The ascending section 9051 is in a threaded shape, and the descending section 9052 is in an inclined straight line shape. The ascending section 9051 and the descending section 9052 are connected end to end. A guide slider 906 is rotatably connected to the inner side of the liquid extraction tube 902 and is placed in the driving groove 905. The guide slider 906 has a long strip profile. When the guide slider 906 passes through the intersection of the ascending section 9051 and the descending section 9052, it can only slide along the section currently placed, so as to prevent the movement trajectory of the guide slider 906 from being unfixed. The separator ring 907 is fixedly connected to the top of the liquid lifting tube 902 and placed on the inner side of the lower centrifugal reaction assembly 7. A plurality of vertical holes are provided on the separator ring 907. During use, the spiral groove sleeve 904 rotates with the driving shaft 2 to make the guide slider 906 slide along the driving groove 905. Affected by the guide slider 906 and the guide sleeve 901, the liquid lifting tube 902 slides up and down rapidly in the vertical direction, and the separator ring 907 moves with the liquid lifting tube 902. When the separator ring 907 moves to a lower position, the bottom of the separator ring 907 slaps the liquid lifted up by the liquid lifting tube 902, so that the liquid moves upward through the holes provided on the separator ring 907, so that the liquid distribution is more uniform. At the same time, in the process of the liquid lifting tube 902 sliding upward, the separator ring 907 will also drive a small amount of liquid upward, further improving the uniformity of liquid distribution.

[0041] It should be noted that the ascending section 9051 and the descending section 9052 have different lengths, so that the ascending speed of the liquid lifting tube 902 is slower than the descending speed, thereby ensuring that the liquid inside the liquid lifting tube 902 can better reach the top of the liquid lifting tube 902 during its descent.

[0042] Specifically, the cleaning component 5 includes a driving ring 501, which is placed in the annular liquid inlet chamber 401. An annular groove 502 is provided on the inner side of the driving ring 501. The annular groove 502 includes an inclined section 5021 and a vertical section 5022. The inclined section 5021 and the vertical section 5022 are connected end to end, and positioning holes 503 that pass through the side wall of the driving ring 501 are provided at the connection positions. The inclined sections 5021 and the vertical sections 5022 are the same in number and are in multiple groups. The number of compression sleeves 504 is the same as that of the dispensing tubes 403, and they correspond one to one in the vertical direction. A locking cavity 505 is provided in each compression sleeve 504. A positioning boss 506 is fixedly connected to one side of each compression sleeve 504. The positioning boss 506 is placed in the annular groove 502. The compression sleeve 504 moves upward to make the positioning boss 506 slide along the inclined section 5021, so that the driving ring 501 rotates. The compression sleeve 504 moves downward to make the positioning boss 506 slide along the vertical section 5022, so that the position of the driving ring 501 is fixed.

[0043] It should be noted that the bottom surfaces of the inclined section 5021 and the vertical section 5022 are both inclined at a small angle, which prevents the positioning boss 506 from pushing the driving ring 501 to rotate in the opposite direction without affecting the positioning boss 506, thereby ensuring that the rotation direction of the positioning boss 506 is fixed.

[0044] More specifically, the cleaning assembly 5 further comprises a push rod 507, which is slidably and sealably connected to the inner side of the compression sleeve 504, the upper end of the push rod 507 is slidably and sealably connected to the inner wall of the compression sleeve 504, and the lower end forms a separate closed chamber with the compression sleeve 504, which is pre-filled with gas, and an L-shaped groove 508 is provided in the middle of each push rod 507. A locking rod 509 is slidably connected to the corresponding locking cavity 505, and one end is placed in the corresponding L-shaped groove 508. The push rod 507 moves up and down through the L-shaped groove 508 to push the locking rod 509 to slide, and the locking rod 509 penetrates the side wall of the compression sleeve 504 and the positioning boss 506. A reset spring 510 is sleeved on the outer side of the push rod 507, and the upper end is fixedly connected to the push rod 507, and the lower end contacts the inner bottom of the compression sleeve 504. The bottom plate 511 is rotatably connected in the annular liquid inlet chamber 401 and is fixedly connected to the driving ring 501. A through hole 512 is opened in the middle of the bottom plate 511. The through hole 512 can correspond to the compression sleeve 504. The through hole 512 can be switched to correspond to different compression sleeves 504 by rotating the driving ring 501.

[0045] It should be noted that when the pressure in the annular liquid inlet chamber 401 is P1, the return spring 510 pushes the push rod 507 to the first height. At this time, the locking rod 509 is placed in the locking chamber 505, and the driving ring 501 is rotated unidirectionally and intermittently through the up and down movement of the compression sleeve 504; when the pressure in the annular liquid inlet chamber 401 is P2, the chamber between the push rod 507 and the compression sleeve 504 is pressurized, causing the push rod 507 to slide downward. At this time, the L-shaped groove 508 pushes the locking rod 509 to slide to the side close to the positioning hole 503. When the positioning boss 506 drives the compression sleeve 504 to slide along the vertical section 5022, when the positioning boss 506 reaches the position where the inclined section 5021 is connected to the vertical section 5022, the locking rod 509 enters the corresponding positioning hole 503. At this time, multiple compression sleeves 504 are placed at the lower end limit position of the vertical section 5022 at the same time, and the compression sleeves 504 are placed at the lower end limit position of the vertical section 5022 at the same time. 504 will not continue to rise, and the push rod 507 reaches the second height. During this process, part of the push rod 507 corresponds to the through hole 512; when the pressure in the annular liquid inlet chamber 401 is P3, the push rod 507 corresponding to the through hole 512 is affected by the pressure, and the chamber between the push rod 507 and the compression sleeve 504 is further compressed, so that the push rod 507 continues to move downward to reach the third height, and at the same time the locking rod 509 is placed in the positioning hole 503, and the push rod 507 that does not correspond to the through hole 512 will not slide downward due to the influence of the bottom plate 511, and still remain at the second height; when the pressure in the annular liquid inlet chamber 401 drops to P1, the return spring 510 pushes the push rod 507 to return to the first height. At this time, the locking rod slides out of the positioning hole 503 and enters the locking chamber 505. At this time, the compression sleeve 504 can continue to slide up and down, causing the driving ring 501 to rotate unidirectionally intermittently.

[0046] It should be pointed out that P1 is smaller than P2, and P2 is smaller than P3.

[0047] It should be further explained that when the pressure in the annular liquid inlet chamber 401 is P2, the chamber between the push rod 507 and the compression sleeve 504 is pressurized, causing the push rod 507 to slide downward. At this time, the L-shaped groove 508 pushes the locking rod 509 to slide toward the side close to the positioning hole 503. When the positioning boss 506 drives the compression sleeve 504 to slide along the inclined section 5021, when the positioning boss 506 reaches the position where the inclined section 5021 is connected to the vertical section 5022, the locking rod 509 enters the corresponding positioning hole 503. At this time, multiple compression sleeves 504 are placed at the upper end limit position of the vertical section 5022 at the same time, and the compression sleeve 504 will not continue to rise. At this time, the push rod 507 reaches the second height.

[0048] Specifically, the cleaning assembly 5 also includes a push rod 513, which is slidably connected to the inner side of the drive shaft 2, and the lower end of which penetrates the side wall of the drive shaft 2, and the lower end of the push rod 513 is fixedly connected to the upper end of the liquid separation ring 907. An inner magnetic ring 514 is fixedly connected to the upper end of the push rod 513, and a plurality of first magnets 515 are fixedly connected to the outer circumferential direction. An outer magnetic ring 516 is slidably connected to the inner side of the annular liquid inlet cavity 401, and a plurality of second magnets 517 are fixedly connected to the inner side of the inner magnetic ring 514. It should be pointed out that the magnetic field directions of the first magnet 515 and the second magnet 517 are opposite, and the first magnet 515 and the second magnet 517 are both permanent magnets, and can attract each other, so that the relative positions of the inner magnetic ring 514 and the outer magnetic ring 516 in the vertical direction are fixed. The support frame 518 is fixedly connected to the outside of the outer magnetic ring 516. Each compression sleeve 504 is fixedly connected to the support frame 518. The support frame 518 is a hollow structure, which can enable the waste liquid to enter the liquid separation tube 403 more smoothly.

[0049] During operation, the liquid lifting tube 902 causes the inner magnetic ring 514 to move up and down through the liquid separating ring 907 and the push rod 513. At the same time, the outer magnetic ring 516 also moves up and down synchronously under the influence of the first magnet 515 and the second magnet 517. The support frame 518 causes the multiple compression sleeves 504 to slide up and down, thereby pushing the driving sleeve 501 to rotate intermittently in one direction. It should be noted that when the locking rod 509 enters the positioning hole 503, the position of the support frame 518 is fixed. When the push rod 513 continues to slide back and forth, the relative positions of the first magnet 515 and the second magnet 517 are disengaged.

[0050] More specifically, the cleaning assembly 5 also includes a dredging rod 519, which is placed in the liquid dispensing tube 403, and a plurality of dredging parts 520 are fixedly connected to the outside, each dredging part 520 is placed in the corresponding nozzle 404, and the dredging rod 519 can slide left and right relative to the liquid dispensing tube 403. An inclined platform 521 is fixedly connected to the upper end of the dredging rod 519, and the inclined platform 521 corresponds to the compression sleeve 504 in the vertical direction. A limiting slide 522 is fixedly connected to the inner side of the annular liquid inlet cavity 401, and the lower end of the dredging rod 519 is placed in the limiting slide 522. A supporting spring 523 is placed between the dredging rod 519 and the corresponding liquid inlet tube 402.

[0051] It should be noted that during use, waste liquid enters nozzle 404 through liquid dispensing tube 403, and is ejected from nozzle 404. At this time, organic matter or other impurities in the waste liquid may block nozzle 404, and nozzle 404 needs to be unblocked. When nozzle 404 is blocked, the pressure sensor detects that the pressure in annular liquid inlet cavity 401 increases to greater than P1, thereby increasing the output pressure of the infusion pump, so that the pressure in annular liquid inlet cavity 401 reaches P2, so that part of the ejector rod 507 corresponds to the through hole 512, and then the pressure is increased to P3. In this process, The push rod 507 corresponding to the through hole 512 is affected by the pressure, further compressing the chamber between the push rod 507 and the compression sleeve 504, so that the push rod 507 continues to move downward to push the inclined platform 521 to make the corresponding dredging rod 519 slide, and the dredging part 520 is inserted into the corresponding through hole 512 to dredge the blocked through hole 512. At the same time, the dredging part 520 blocks a part of the liquid outlet of the nozzle 404. At this time, the position of the push rod 507 that does not correspond to the through hole 512 remains unchanged, so that the internal pressure of the corresponding nozzle 404 increases, and the dredging effect is also achieved.

[0052] Furthermore, in order to clear each nozzle 404 by acupuncture and pressurization in a variety of ways when blocked, the pressure in the annular liquid inlet chamber 401 reaches P1, the reset spring 510 pushes the push rod 507 to the first height, and the driving ring 501 is rotated intermittently in one direction by the up and down movement of the compression sleeve 504. When the through hole 512 on the bottom plate 511 rotates to the bottom of the compression sleeve 504 that was blocked last time, the pressure in the annular liquid inlet chamber 401 is adjusted to P2 again, so that the locking rod 504 is locked. 09 is placed in the positioning hole 503 on the lower side of the vertical section 5022, and then the pressure in the annular liquid inlet chamber 401 is adjusted to P3, and the top rod 507 that was blocked last time moves downward, so that the corresponding dredging part 520 penetrates into the corresponding nozzle 404, and at the same time, the pressure of the nozzle 404 that was punctured last time increases; the pressure in the annular liquid inlet chamber 401 is repeatedly adjusted in this way so that each nozzle 404 can be dredged by acupuncture and pressurization, thereby improving the dredging effect of the nozzle 404 and thereby improving the working efficiency of the reactor.

[0053] It should be pointed out that the rotation speed of the driving motor 3 can be controlled by existing technology. Therefore, in the process of adjusting the pressure in the annular liquid inlet chamber 401 from P3 to P1, the rotation angle of the driving ring 501 can be ensured, and then it can be determined that each time the pressure in the annular liquid inlet chamber 401 is adjusted, the push rod 507 in different positions can correspond to the through hole 512.

[0054] When it is necessary to complete the waste liquid treatment quickly and efficiently, in the process of the positioning boss 506 driving the compression sleeve 504 to slide along the inclined section 5021, the pressure in the annular liquid inlet chamber 401 is adjusted to P2. When the positioning boss 506 reaches the position where the inclined section 5021 is connected to the vertical section 5022, the locking rod 509 enters the corresponding positioning hole 503. At this time, multiple compression sleeves 504 are placed at the upper end limit position of the vertical section 5022 at the same time, and then the pressure can be increased to P3. At this time, the push rod 507 drops to the third height and cannot contact the inclined platform 521, so that the dredging part 520 will not enter the nozzle 404, causing the nozzle 404 to be blocked. At this time, the pressure in the liquid dispensing tube 403 increases, which can improve the liquid discharge efficiency of the nozzle 404, and at the same time increase the rotation speed of the drive shaft 2, so that the working efficiency of the reactor is increased; but when the nozzle 404 is blocked, it is still necessary to proceed with the above-mentioned dredging method.

[0055] Specifically, the upper centrifugal reaction assembly 6 includes an upper packing layer 601, which is annularly sleeved on the outer side of the annular liquid inlet chamber 401. A gas dispersion plate 602, which is fixedly connected to the upper end of the upper packing layer 601 and is sealed and rotatably connected to the inner wall of the reactor shell 1. A plurality of jet pipes 603, which are fixedly connected to the outer side of the gas dispersion plate 602, are evenly distributed along the circumference of the gas dispersion plate 602. The jet pipes 603 uniformly spray the input gas into the reactor shell 1, so that the gas in the reactor shell 1 is evenly distributed. An air outlet ring 604, which is fixedly connected to the upper end of the gas dispersion plate 602 and sleeved on the outer side of the annular liquid inlet chamber 401, separates the input gas from the output gas to prevent the output gas from being discharged with the output gas without reacting with the liquid phase, thereby reducing the reaction efficiency. The particle collection assembly 605 is fixedly mounted on the lower end of the upper packing layer 601 and fixedly connected to the driving shaft 2, and is used to collect solid impurities in the waste liquid.

[0056] More specifically, the lower centrifugal reaction assembly 7 includes a lower packing layer 701, which is sleeved on the outer side of the liquid separation ring 907. An upper fixed plate 702 is fixedly connected to the upper end of the lower packing layer 701 and is fixedly connected to the drive shaft 2. A lower fixed plate 703 is fixedly connected to the lower end of the lower packing layer 701 and is rotatably connected to the secondary reaction liquid tank 8.

[0057] It should be noted that both the upper packing layer 601 and the lower packing layer 701 use existing packing layers. Under the action of centrifugal force, the waste liquid flows to the outer edges of the upper packing layer 601 and the lower packing layer 701. In this process, the waste liquid is dispersed and broken by the shear force of the packing, forming liquid filaments, liquid films, and droplets that are not easily formed under conventional working conditions, thereby forming good mass transfer and reaction conditions.

[0058] Specifically, the particle collection assembly 605 includes a guide plate 6051, which is fixedly connected to the lower end of the upper packing layer 601, and the guide plate 6051 is umbrella-shaped, so that the liquid after the reaction through the upper packing layer 601 enters the inner lower end of the reactor shell 1. The collection tank 6052 is opened in the middle of the guide plate 6051 and is placed below the annular liquid inlet cavity 401. The scraper 6053 is fixedly connected to the outer side of the annular liquid inlet chamber 401, and multiple scrapers are evenly arranged in the circumferential direction, which are used to scrape off impurities. During the operation, the waste liquid is evenly sprayed on the inner side of the upper packing layer 601 through the nozzle 404, so that the waste liquid undergoes a supergravity reaction. However, during the reaction, some impurities cannot pass through the upper packing layer 601 and are blocked on the inner side of the upper packing layer 601. During the operation, the upper packing layer 601 rotates so that the impurities are guided by the scraper 6053 to the collecting tank 6052. The collecting tank 6052 is in the shape of a truncated cone with a smaller diameter at the upper end. After entering, the impurities are affected by the centrifugal force and move downward, preventing the impurities from entering the inner side of the upper packing layer 601, and completing the cleaning of the impurities on the inner side of the upper packing layer 601. The discharge notches 6054 are evenly distributed and opened in the circumference of the collecting tank 6052. The flip plate 6055 is rotatably connected in the discharge notch 6054. A reset spring 6056 is provided on one side of each flip plate 6055. The other end of the reset spring 6056 is fixedly connected to the side wall of the discharge notch 6054. During operation, the guide plate 6051 rotates rapidly, and the flip plate 6055 blocks the discharge notch 6054 due to the centrifugal force. At the same time, the reset spring 6056 is compressed. When the work is completed, the speed of the guide plate 6051 decreases, the centrifugal force on the flip plate 6055 decreases, and the reset spring 6056 pushes the flip plate 6055 out of the discharge notch 6054. At this time, the impurities in the collecting tank 6052 are discharged through the discharge notch 6054.

[0059] It should be noted that when cleaning the reactor, the drive shaft 2 is rotated slowly, and cleaning agent or clean water is slowly injected into the reactor shell 1 through the liquid distribution component 4, so that part of the cleaning agent or clean water can enter the collection tank 6052 to clean the collection tank 6052.

[0060] More specifically, the upper end of the reactor shell 1 is connected with an air outlet pipe 10 and an air inlet pipe 11. The air outlet pipe 10 is connected to the inner side of the air outlet collar 604, and the air inlet pipe 11 is connected to the outer side of the air outlet collar 604. The end of the air inlet pipe 11 is connected to an air pump for conveying gas into the reactor shell 1. The air pump is a prior art and will not be described in detail here. It is not shown in the figure. The air outlet pipe 10 is connected to subsequent process equipment. An air guide pipe 12 is provided on the inner side of the drive shaft 2. The lower end of the air guide pipe 12 is connected to the inner side of the lower packing layer 701, and the upper end of the air guide pipe 12 is connected to the inner side of the air outlet collar 604. The air guide pipe 12 guides the reacted gas inside the lower packing layer 701 to the air outlet collar 604. The push rod 513 is placed in the air guide pipe 12 and does not affect the gas flow in the air guide pipe 12. The lower end of the reactor shell 1 is connected to a primary drain pipe 13, and the lower end of the secondary reaction liquid tank 8 is connected to a secondary drain pipe 14. The secondary drain pipe 14 runs through the lower end of the reactor shell 1. Both the primary drain pipe 13 and the secondary drain pipe 14 are connected to subsequent processes. During operation, the primary drain pipe 13 or the secondary drain pipe 14 can be selected to discharge the reacted liquid according to the demand for the organic matter content of the waste liquid after the reaction. The organic matter content of the liquid discharged by the secondary drain pipe 14 is lower than that of the liquid discharged by the primary drain pipe 13.

[0061] It should be noted that when cleaning the reactor, the liquid is first discharged through the secondary drain pipe 14 so that the lower centrifugal reaction assembly 7 can be effectively cleaned, and then all the liquid in the reactor shell 1 is discharged through the primary drain pipe 13 to achieve the purpose of cleaning the reactor.

[0062] Meanwhile, during the cleaning process, the pressure in the annular liquid inlet cavity 401 can still be adjusted, so that each nozzle 404 can be cleared and cleaned by acupuncture to push the obstruction and high-pressure flushing.

[0063] In summary, when it is necessary to recycle the waste liquid through supergravity reaction, first, the end of the air inlet pipe 11 is connected to the air pump, the air outlet pipe 10 is connected to the subsequent process equipment, and the first-level discharge pipe 13 and the second-level discharge pipe 14 are connected to the subsequent process, and then the reaction gas is injected into the reactor shell 1 through the air pump, and the drive motor 3 is started to make the upper centrifugal reaction component 6 and the lower centrifugal reaction component 7 rotate rapidly to generate centrifugal force, and then the waste liquid is transported to the annular liquid inlet cavity 401 through the infusion pump, and sprayed out from the nozzle 404, so that the waste liquid enters the inner side of the upper packing layer 601. At this time, the waste liquid is divided and crushed by the packing layer, and then contacts with the gas to react. The reacted liquid flows to the bottom of the reactor shell 1. At the same time, under the influence of the guide slider 906 and the guide sleeve 901, the liquid lifting tube 902 slides up and down rapidly in the vertical direction, and the liquid lifting tube 902 slides upward. Under the influence of inertia, the sealing cover plate 903 sticks to the liquid lifting tube 902. The upper end of the liquid lifting tube 902 is closed, and the liquid lifting tube 902 attracts the liquid inside the guide sleeve 901. Then the liquid lifting tube 902 drops rapidly. Under the influence of inertia, the liquid in the liquid lifting tube 902 flows upward. At the same time, the sealing cover plate 903 is also opened under the influence of inertia, so that the liquid in the liquid lifting tube 902 reaches the upper end of the liquid lifting tube 902. In the process of the liquid lifting tube 902 floating up and down rapidly, the liquid inside the guide sleeve 901 is transported to the top of the liquid lifting tube 902 and enters the inner side of the lower packing layer 701, and a secondary supergravity reaction is carried out through the lower packing layer 701. The liquid passing through the lower packing layer 701 enters the secondary reaction liquid tank 8. At this time, the reacted liquid can be discharged through the secondary drain pipe 14. At the same time, the gas passing through the lower packing layer 701 enters the gas outlet ring 604 through the gas guide pipe 12, and the gas passing through the upper packing layer 601 also enters the gas outlet sleeve, and the reacted gas is discharged through the gas outlet pipe 10.

[0064] When the equipment is in normal operation, the liquid lifting tube 902 causes the inner magnetic ring 514 to move up and down through the liquid separation ring 907 and the push rod 513. At the same time, the outer magnetic ring 516 also moves up and down synchronously under the influence of the first magnet 515 and the second magnet 517, and the pressure in the annular liquid inlet cavity 401 is controlled to be P1 through the infusion pump. At this time, the locking rod 509 is placed in the locking cavity 505, and the driving sleeve 501 is rotated intermittently in one direction through the up and down movement of the compression sleeve 504; when organic matter or other impurities in the waste liquid block the nozzle 404, the pressure sensor detects that the pressure in the annular liquid inlet cavity 401 increases to greater than P1, thereby increasing the output pressure of the infusion pump. When the positioning boss 506 drives the compression sleeve 504 to slide along the vertical section 5022, the pressure in the annular liquid inlet chamber 401 reaches P2, and the chamber between the push rod 507 and the compression sleeve 504 is pressurized, causing the push rod 507 to slide downward. At this time, the L-shaped groove 508 pushes the locking rod 509 to slide toward the side close to the positioning hole 503, and then the locking rod 509 enters the corresponding positioning hole 503. At this time, multiple compression sleeves 504 are placed at the lower end limit position of the vertical section 5022 at the same time, and the compression sleeve 504 will not continue to rise, and then the pressure is increased to P3. In this process, the push rod 507 corresponding to the through hole 512 is affected by the pressure, causing the push rod 5 07 continues to move downward to push the inclined platform 521 to make the corresponding dredging rod 519 slide, and the dredging part 520 is inserted into the corresponding through hole 512 to dredge the blocked through hole 512. At the same time, the dredging part 520 blocks a part of the liquid outlet of the nozzle 404. At this time, the position of the push rod 507 that does not correspond to the through hole 512 remains unchanged, so that the internal pressure of the corresponding nozzle 404 increases, and the dredging effect is also achieved. Then, the pressure in the annular liquid inlet cavity 401 reaches P1, and the reset spring 510 pushes the push rod 507 to the first height, driving the ring 501 to rotate. When the through hole 512 on the bottom plate 511 rotates to the compression sleeve 504 that was blocked last time When it is down, the pressure in the annular liquid inlet chamber 401 is adjusted to P2 again, so that the locking rod 509 is placed in the positioning hole 503 on the lower side of the vertical section 5022, and then the pressure in the annular liquid inlet chamber 401 is adjusted to P3, and the top rod 507 that was blocked last time moves downward, so that the corresponding dredging part 520 penetrates into the corresponding nozzle 404, and at the same time, the pressure of the nozzle 404 that was punctured last time increases; the pressure in the annular liquid inlet chamber 401 is repeatedly adjusted in this way so that each nozzle 404 can be dredged by acupuncture and pressurization, and the equipment can still operate stably during the dredging process, and after the dredging is completed, the pressure in the annular liquid inlet chamber 401 is adjusted to remain at P1.

[0065] When it is necessary to complete the waste liquid treatment quickly and efficiently, while the positioning boss 506 drives the compression sleeve 504 to slide along the inclined section 5021, the pressure in the annular liquid inlet chamber 401 is adjusted to P2, the locking rod 509 enters the corresponding positioning hole 503, and the compression sleeve 504 is placed at the upper limit position of the vertical section 5022, and then the pressure can be increased to P3. At this time, the top rod 507 drops to the third height and cannot contact the inclined platform 521, so that the dredging part 520 will not enter the nozzle 404. At this time, the pressure in the liquid dispensing tube 403 increases, which can improve the liquid discharge efficiency of the nozzle 404. At the same time, the rotation speed of the drive shaft 2 is increased, so that the working efficiency of the reactor is increased. However, when the nozzle 404 is blocked, it is still necessary to deal with it according to the above-mentioned dredging method.

[0066] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
