Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a spray absorption treatment device supporting a distillation tower. Background Art

[0002] In many industrial fields such as chemical, petroleum, environmental protection, pharmaceuticals, and food processing, distillation towers play an extremely critical role and are the core equipment for achieving precise separation and efficient purification of mixtures. The distillation process is based on the differences in boiling points of different substances and separates the components in the mixture through multiple vaporization and condensation. However, this process will produce waste gas and wastewater containing various pollutants. If these pollutants are discharged directly without treatment, they will cause serious pollution to the atmosphere, water bodies and soil environment, endanger the ecological balance, and threaten human health and biodiversity.

[0003] A search of CN119285009A discloses a spray absorption treatment equipment for a distillation tower, comprising two packing plates positioned one above and one below in the distillation tower, a spray water distributor positioned on the inner wall of the distillation tower above the packing plate in the upper position, and a diversion release module above both packing plates. In the present invention, sewage enters the interior of the central pipe column in a unified manner, and is dispersedly released from different areas in the packing layer by a number of annularly distributed angular release pipe columns, while extending the release path of the sewage and slowing down the flow rate and flow rate. The gas planning and guiding module guides part of the reaction gas to enter the interior of the two conical converging buckets in turn, allowing the reaction gas to pre-contact the sewage inside the conical converging bucket to effectively carry out a round of sewage pretreatment, and then release it into the packing for re-absorption treatment after increasing the contact treatment time, thereby increasing the contact treatment time between the sewage and the reaction gas and improving the spray absorption effect of the distillation tower.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0005] In actual use, it was found that during the gas-liquid mixing reaction process, the reaction efficiency was low due to the limited gas-liquid contact area. A simple spray device would cause uneven gas-liquid mixing, making it difficult to fully remove pollutants. In addition, the equipment lacked an effective impurity filtering and cleaning mechanism, and impurities were easily accumulated, which not only affected the normal operation of the equipment, but also required frequent shutdowns for manual cleaning, reducing production efficiency and increasing operating costs.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0034] like Figures 1 to 7As shown, a spray absorption treatment device supporting a distillation tower includes a shell 1, two rotating covers 3 are rotatably installed in the shell 1, a rotating shaft 2 for conveying reaction gas is assembled in the rotating cover 3, and a driving assembly for driving the rotating shaft 2 to rotate is installed at the bottom of the rotating shaft 2;

[0035] An impurity cleaning mechanism for cleaning impurities is installed on the top of the rotating shaft 2, and a filter plate 4 is provided at the bottom of the impurity cleaning mechanism, and the filter plate 4 is installed on the rotating shaft 2;

[0036] A water collecting plate 17 and two packing layers 13 are installed in the housing 1. Scrapers 15 are installed on both packing layers 13. The scrapers 15 are connected to the rotating shaft 2. The bottom of one packing layer 13 is in contact with the water collecting plate 17. The other packing layer 13 is arranged on the top of one of the rotating covers 3. The other rotating cover 3 is installed below the filter plate 4.

[0037] The rotating cover 3 includes an inclined plate 5 and a bottom plate 7. A pretreatment chamber 6 is provided between the inclined plate 5 and the filter plate 4. A gas storage chamber 8 is provided between the inclined plate 5 and the bottom plate 7. In this arrangement, the shell 1 serves as the main structure of the equipment, protecting the internal components and accommodating the reaction process. The rotating cover 3 separates different working areas. The rotating shaft 2 transmits the reaction gas and rotates under the action of the driving assembly, driving the rotating cover 3 and other related components to operate and realize the dynamic reaction process of the equipment. The driving assembly provides rotational power for the rotating shaft 2 so that the various rotating components in the equipment can work together. The impurity cleaning mechanism removes impurities on the filter plate 4 to ensure the normal operation and filtering effect of the equipment. The filter plate 4 filters sewage, etc., separates impurities, and ensures that the substances entering the subsequent treatment links meet the requirements. The water collecting plate 17 collects the treated liquid, the packing layer 13 increases the gas-liquid contact area, promotes the reaction, and improves the treatment efficiency. The scraper 15 rotates with the rotating shaft 2, scraping the solid particles in the packing layer 13 to enhance the reaction effect. The inclined plate 5 constitutes the boundary between the pretreatment chamber 6 and the gas storage chamber 8, and promotes the mixing reaction of sewage and reaction gas during the rotation process, and guides the flow of liquid. The bottom plate 7 and the inclined plate 5 together form the rotating cover 3, which closes the gas storage chamber 8. The pretreatment chamber 6 performs preliminary treatment on the sewage to prepare for subsequent reactions. The gas storage chamber 8 stores the reaction gas so that it can be sprayed out as needed to participate in the reaction.

[0038] like Figures 1 to 7As shown, in a specific embodiment, the drive assembly includes a motor 22, an output shaft 21 is mounted on the motor 22, a driving gear 20 is assembled on the output shaft 21, a driven gear 19 is meshed with the driving gear 20, and the driven gear 19 is assembled on the rotating shaft 2. In this configuration, the motor 22 serves as a power source, providing power output that converts electrical energy into mechanical energy. The output shaft 21 transmits the rotation of the motor 22 to the driving gear 20, and the driving gear 20 meshes with the driven gear 19. The speed and torque are changed through gear transmission to drive the rotating shaft 2 to rotate. The driven gear 19 cooperates with the driving gear 20 to transmit power to the rotating shaft 2, thereby realizing the rotation of the rotating shaft 2.

[0039] like Figures 1 to 7 As shown, further, the impurity cleaning mechanism includes a support column 24 and a shovel plate 31, a collector 35 is sleeved on the support column 24, a guide groove 25 is opened on the support column 24, a guide block 41 is slidably installed in the guide groove 25, an annular plate 26 is slidably installed on the support column 24, the guide block 41 is installed inside the annular plate 26, a rotating shaft 28 is installed on the annular plate 26, a rotating plate 29 is rotatably installed on the rotating shaft 28, a torsion spring 42 is sleeved on the rotating shaft 28, one end of the torsion spring 42 is connected to the annular plate 26, and the other end is connected to the rotating plate 29, the end of the rotating plate 29 is connected to the guide plate 30, and the end of the guide plate 30 is connected to the shovel plate 31. In this arrangement, the support column 24 provides support for the collector 35, the annular plate 26 and other components to ensure the structural stability of the impurity cleaning mechanism. The shovel plate 31 scoops up impurities on the filter plate 4 to separate the impurities from the liquid. The collector 35 collects the impurities scooped up and dropped by the shovel plate 31 for centralized processing. The guide groove 25 and the guide block 41 cooperate with the guide rod 27 to enable the annular plate 26 to slide back and forth along the guide rod 27. The annular plate 26 acts as a connecting component to transmit motion and support components such as the rotating plate 29. The rotating shaft 28 enables the rotating plate 29 to rotate around it to realize the flipping action of the shovel plate 31. The torsion spring 42 can ensure that the rotating plate 29 and the shovel plate 31 do not rotate without the action of the push rod 34. The rotating plate 29 drives the shovel plate 31 to move through the guide plate 30 to realize the lifting and flipping of the shovel plate 31.

[0040] like Figures 1 to 7 As shown, the shovel plate 31 is provided with an inclined surface 32 for scooping up impurities, and one side of the guide plate 30 mounted on the shovel plate 31 is inclined. In this arrangement, the inclined surface 32 facilitates scooping up impurities on the filter plate 4, improving the efficiency of impurity cleaning, and the inclined guide plate 30 can transport impurities to the collector 35.

[0041] like Figures 1 to 7As shown, a push rod 34 and a guide rod 27 are installed in the housing 1. The push rod 34 and the guide rod 27 are installed in a suspended state inside the housing 1. The annular plate 26 is slidably mounted on the guide rod 27, and the push rod 34 is installed above the rotating plate 29. In this arrangement, when the rotating plate 29 moves to a specific position with the annular plate 26, the push rod 34 pushes the rotating plate 29 to rotate about the rotation axis 28, thereby achieving the flipping of the shovel plate 31. The guide rod 27 rotates the rotation of the annular plate 26, ensuring the smoothness and directionality of the movement of the annular plate 26.

[0042] like Figures 1 to 7 As shown, a reaction chamber 14 is provided between each of the two rotating covers 3 and the two packing layers 13. A modular ring 38 is installed in each of the reaction chambers 14. Several inclined flushing pipes 39 are connected to the modular rings 38. A water inlet pipe 40 is connected between the two modular rings 38. In this arrangement, the reaction chambers 14 provide space for further reaction between the sewage and the reaction gas. The modular rings 38 connect the water inlet pipe 40 and the inclined flushing pipes 39, allowing flushing water to be evenly distributed to the inclined flushing pipes 39. The inclined flushing pipes 39 release flushing water from different directions into the packing layers 13, impacting the packing and promoting the separation and absorption of sewage and reaction gas. The water inlet pipe 40 guides the flushing water into the modular rings 38, providing a water source for the inclined flushing pipes 39.

[0043] like Figures 1 to 7 As shown, several first nozzles 11 are mounted on the inclined plate 5 within the rotating hood 3. Several delivery pipes 9 are mounted at the bottom of the inclined plate 5. Each delivery pipe 9 extends through the bottom plate 7 and into the reaction chamber 14. In this arrangement, the first nozzles 11 eject the reaction gas from the gas storage chamber 8 to pre-treat the wastewater in the pre-treatment chamber 6, promoting the gas-liquid reaction. The delivery pipes 9 then transport the pre-treated wastewater from the pre-treatment chamber 6 to the reaction chamber 14 for subsequent treatment.

[0044] like Figures 1 to 7 As shown, a through hole 12 is formed on the rotating shaft 2, connecting the gas storage chamber 8 with the rotating shaft 2. A purified water receiving chamber 10 is provided between the water collecting plate 17 and the packing layer 13. A drain pipe 18 is connected to the water collecting plate 17. Three groups of second nozzles 16 are installed on the rotating shaft 2, one group of second nozzles 16 is installed in the purified water receiving chamber 10, and the other two groups of second nozzles 16 are installed in the reaction chamber 14. In this arrangement, the through hole 12 connects the gas storage chamber 8 with the rotating shaft 2, allowing the reaction gas to enter the gas storage chamber 8 and be transported to other parts. The purified water receiving chamber 10 receives the treated purified water and waits for it to be discharged from the equipment. The drain pipe 18 discharges the purified water in the purified water receiving chamber 10 out of the equipment. The second nozzles 16 spray the reaction gas or other treatment liquids in the purified water receiving chamber 10 and the reaction chamber 14 to further treat the sewage or disinfect the purified water.

[0045] like Figures 1 to 7As shown, an air inlet pipe 23 is installed at the bottom of the housing 1, and a rotating shaft 2 is rotatably installed in the air inlet pipe 23. In this configuration, the air inlet pipe 23 serves as an inlet for the reaction gas, guiding the reaction gas into the rotating shaft 2.

[0046] like Figures 1 to 7 As shown, a vertical rod 33 is installed in the housing 1. The vertical rod 33 is installed in a suspended state inside the housing 1. A water distributor 36 is installed at the bottom of the vertical rod 33, and a sewage inlet pipe 37 is connected to the water distributor 36. In this configuration, the vertical rod 33 is suspended inside the housing 1 to provide support for the water distributor 36. The water distributor 36 evenly distributes the sewage transported by the sewage inlet pipe 37, allowing it to better enter the equipment for treatment. The sewage inlet pipe 37 guides the sewage into the equipment and is the inlet pipe for the sewage to enter the treatment process.

[0047] The implementation principle of the spray absorption treatment equipment for a distillation tower according to the present embodiment is as follows: when treating sewage, the sewage flows from the sewage inlet pipe 37 into the water distributor 36. At the same time, the motor 22 is turned on, and the output shaft 21 installed on the motor 22 drives the driving gear 20 to rotate. The driving gear 20 and the driven gear 19 are meshed with each other, thereby driving the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 drives the rotating cover 3 and other components installed thereon to operate synchronously. During this period, the water distributor 36 releases the sewage evenly. During the operation of the equipment, the impurity cleaning mechanism starts to work, and the filter plate 4 rotates with the rotating shaft 2, while the shovel plate 31 remains stationary. The inclined surface 32 on the shovel plate 31 can shovel up the impurities on the filter plate 4. When the filter plate 4 rotates with the support column 2 4 and after the rotating shaft 2 rotates a certain angle, the guide groove 25 on the support column 24 cooperates with the guide block 41 on the annular plate 26, so that the annular plate 26 can slide upward along the guide rod 27. When the rotating plate 29 moves to the position of the push rod 34 with the annular plate 26, the push rod 34 pushes the rotating plate 29 to rotate around the rotating shaft 28, and drives the shovel plate 31 to flip through the guide plate 30. At this time, the torsion spring 42 is subjected to torsion, and the cooperation of the guide groove 25 on the support column 24 and the guide block 41 on the annular plate 26 will keep the shovel plate 31 in an inclined state for a certain period of time. Then, the impurities fall into the collector 35 through the guide plate 30, thereby completing the impurity cleaning work. Immediately afterwards, the coordinated action of the guide groove 25 and the guide block 41 allows the annular plate 26 to move downward. During the process, the torsion spring 42 will drive the rotating plate 29 to rotate in the opposite direction around the rotating shaft 28. When the annular plate 26 contacts the filter plate 4, all components are reset, and the sewage filtered by the filter plate 4 enters the pretreatment chamber 6. At this time, the reaction gas enters the rotating shaft 2 through the air inlet pipe 23, and enters the gas storage chamber 8 through the through hole 12 on the rotating shaft 2, and is then ejected by several first nozzles 11 installed on the inclined plate 5. Since the inclined plate 5 rotates with the rotating shaft 2, it can not only fully mix the sewage and the reaction gas, but also make the sewage vibrate up and down, further promoting the reaction between the two. The first nozzle 11 is located on the inclined plate 5, and the reaction gas moves upward from the bottom of the sewage, which greatly improves the sufficiency of the reaction. Subsequently, the sewage enters the reaction chamber 14 through the conveying pipe 9. The second nozzle 16 injects the reaction gas to react with the pretreated sewage again. After the sewage enters the reaction chamber 14, it will fall into the packing layer 13 and further react. The scraper 15 will scrape the solid particles in the packing layer 13 to enhance the reaction effect. The treated sewage then enters the next pretreatment chamber 6 and the reaction chamber 14 for further treatment. During this process, the water inlet pipe 40 guides the flushing water into the combination ring 38 and then flows into the flushing inclined pipe 39. Several flushing inclined pipes 39 release the flushing water to different areas of the packing from different directions, impacting the packing from the inside, allowing the sewage and the reaction gas to be continuously separated and absorbed in the packing. Finally, the treated water falls on the water collecting plate 17, flows into the purified water receiving chamber 10, and finally is discharged from the equipment through the drain pipe 18.The various components work together to continuously clean the inflowing sewage of impurities, spray reaction and other treatment processes, thereby achieving sewage purification. Through the mechanical linkage between the various components, this equipment achieves efficient operation of sewage impurity cleaning and purification treatment, improving sewage treatment efficiency and quality.
