Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and specifically relates to a spray absorption treatment device for a rectifying column. Background Art

[0002] In many industrial fields such as chemical engineering, petroleum, environmental protection, pharmaceuticals, and food processing, rectifying columns play a crucial role and are the core equipment for achieving precise separation and efficient purification of mixtures. The rectification process is based on the boiling point differences of different substances, and through multiple vaporizations and condensations, the components in the mixture are separated. However, in this process, waste gas and wastewater containing various pollutants will be generated. If these pollutants are directly discharged 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] After retrieval, CN119285009A discloses a spray absorption treatment device for a rectifying column, which includes two packing plates positioned one above the other in the rectifying column. Above the packing plate in the upper position, a spray water distributor positioned on the inner wall of the rectifying column is provided. Above both of the two packing plates, a flow splitting and releasing module is provided. In the present invention, sewage uniformly enters the central pipe column, and is dispersedly released from different regions in the packing layer by a plurality of annularly distributed angular release pipe columns. At the same time, the release path of the sewage is extended, and the flow rate and flow volume are slowed down. The gas planning and guiding module guides part of the reaction gas to sequentially enter the two conical converging hoppers, allowing the reaction gas to pre-contact the sewage inside the conical converging hoppers to effectively perform a round of pre-treatment of the sewage, improving the contact treatment time and then releasing it into the packing for re-absorption treatment, increasing the contact treatment time between the sewage and the reaction gas, and improving the spray absorption effect of the rectifying column.

[0004] However, through the exploration of the inventor, it is found that this technical solution still has at least the following defects: In actual use, it is found that during the gas-liquid mixing reaction process, due to the limited gas-liquid contact area, the reaction efficiency is low. A simple spray device will cause uneven gas-liquid mixing, making it difficult to fully remove pollutants. In addition, the device lacks an effective impurity filtering and cleaning mechanism, and impurities are prone to accumulate, which will not only affect the normal operation of the device, but also require frequent shutdowns for manual cleaning, reducing production efficiency and increasing operating costs.

Detailed implementation mode

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0021] As Figures 1 to 7 shown, a spray absorption treatment device supporting a rectifying tower includes a housing 1. Two rotating covers 3 are rotatably installed in the housing 1. A rotating shaft 2 for conveying reaction gas is assembled in the rotating cover 3. A driving assembly for driving the rotation of the rotating shaft 2 is installed at the bottom of the rotating shaft 2; An impurity cleaning mechanism for cleaning impurities is installed at the top of the rotating shaft 2. A filter plate 4 is arranged at the bottom of the impurity cleaning mechanism. The filter plate 4 is installed on the rotating shaft 2; A water collecting plate 17 and two packing layers 13 are installed in the housing 1. Scrapers 15 are installed on both of the two 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, and 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; The rotating cover 3 includes an inclined plate 5 and a bottom plate 7. A pretreatment chamber 6 is arranged between the inclined plate 5 and the filter plate 4, and a gas storage chamber 8 is arranged between the inclined plate 5 and the bottom plate 7. In this setting, the housing 1 serves as the main structure of the device, playing a role in 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, realizing the dynamic reaction process of the device. The driving assembly provides rotational power for the rotating shaft 2, enabling the rotating components in the device to work together. The impurity cleaning mechanism removes impurities on the filter plate 4, ensuring the normal operation of the device and the filtering effect. The filter plate 4 filters sewage and other substances, separating out impurities to ensure that the substances entering the subsequent treatment link 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 forms the boundary of the pretreatment chamber 6 and the gas storage chamber 8, promoting the mixing reaction of sewage and reaction gas during rotation and guiding the liquid flow. The bottom plate 7 and the inclined plate 5 together form the rotating cover 3, enclosing the gas storage chamber 8. The pretreatment chamber 6 conducts preliminary treatment on the sewage to prepare for the subsequent reaction. The gas storage chamber 8 stores the reaction gas for spraying and participating in the reaction as needed.

[0022] As Figures 1 to 7 shown, in a specific embodiment, the driving assembly includes a motor 22. An output shaft 21 is installed on the motor 22. A driving gear 20 is assembled on the output shaft 21. A driven gear 19 meshes with the driving gear 20. The driven gear 19 is assembled on the rotating shaft 2. In this setting, the motor 22 serves as the power source, providing a 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. The driving gear 20 meshes with the driven gear 19, changing the rotational speed and torque through gear transmission to drive the rotating shaft 2 to rotate. The driven gear 19 cooperates with the driving gear 20 to transmit the power to the rotating shaft 2, realizing the rotation of the rotating shaft 2.

[0023] As Figures 1 to 7As shown in the figure, 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 formed in 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 a guide plate 30, and the end of the guide plate 30 is connected to a shovel plate 31. In this setting, the support column 24 provides support for components such as the collector 35 and the annular plate 26, ensuring the structural stability of the impurity cleaning mechanism. The shovel plate 31 shovels up the impurities on the filter plate 4 to achieve the separation of impurities and liquid. The collector 35 collects the impurities shoveled up by the shovel plate 31 and then dropped, facilitating centralized treatment. The guide groove 25 and the guide block 41 cooperate with the guide rod 27 to enable the annular plate 26 to slide up and down reciprocally along the guide rod 27. The annular plate 26 serves 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, realizing 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 ejector rod 34. The rotating plate 29 drives the shovel plate 31 to move through the guide plate 30, realizing the lifting and flipping of the shovel plate 31.

[0024] As Figures 1 to 7 shown, the shovel plate 31 is provided with an inclined surface 32 for shoveling up impurities, and one side of the guide plate 30 installed on the shovel plate 31 is inclined. In this setting, the inclined surface 32 facilitates shoveling up the impurities on the filter plate 4, improving the impurity cleaning efficiency. The inclined guide plate 30 can convey the impurities into the collector 35.

[0025] As Figures 1 to 7 shown, a top rod 34 and a guide rod 27 are installed in the housing 1. The top rod 34 and the guide rod 27 are installed in a suspended state inside the housing 1. The annular plate 26 is slidably installed on the guide rod 27. The top rod 34 is installed above the rotating plate 29. In this setting, when the rotating plate 29 moves to a specific position along with the annular plate 26, the top rod 34 pushes the rotating plate 29 to rotate around the rotating shaft 28, thereby realizing the flipping of the shovel plate 31. The guide rod 27 guides the rotation of the annular plate 26, ensuring the smoothness and directionality of the movement of the annular plate 26.

[0026] As Figures 1 to 7As shown, reaction chambers 14 are provided between the two rotating covers 3 and the two packing layers 13 respectively. Combination rings 38 are installed in both of the two reaction chambers 14. A number of flushing inclined pipes 39 are connected to the combination rings 38, and a water inlet pipe 40 is connected between the two combination rings 38. In this setting, the reaction chamber 14 provides space for the further reaction of sewage and reaction gas. The combination ring 38 connects the water inlet pipe 40 and the flushing inclined pipes 39, enabling the flushing water to be evenly distributed to the flushing inclined pipes 39. The flushing inclined pipes 39 release the flushing water into the packing layer 13 from different directions, impacting the packing to promote the separation and absorption of sewage and reaction gas. The water inlet pipe 40 guides the flushing water into the combination ring 38 to provide water source for the flushing inclined pipes 39.

[0027] As Figures 1 to 7 shown, a number of first nozzles 11 are installed in the inclined plate 5 of the rotating cover 3, and a number of conveying pipes 9 are installed at the bottom of the inclined plate 5. Each conveying pipe 9 passes through the bottom plate 7 and leads into the reaction chamber 14. In this setting, the first nozzles 11 eject the reaction gas in the gas storage chamber 8 to pre-treat the sewage in the pretreatment chamber 6, promoting the gas-liquid reaction. The conveying pipes 9 convey the pre-treated sewage from the pretreatment chamber 6 to the reaction chamber 14 for subsequent treatment.

[0028] As Figures 1 to 7 shown, through holes 12 are formed in the rotating shaft 2. The through holes 12 connect the gas storage chamber 8 and the rotating shaft 2. A purified water storage 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 storage chamber 10, and the other two groups of second nozzles 16 are installed in the reaction chamber 14. In this setting, the through holes 12 connect the gas storage chamber 8 and the rotating shaft 2, enabling the reaction gas to enter the gas storage chamber 8 and be conveyed to other parts. The purified water storage chamber 10 stores the treated purified water, waiting to be discharged from the device. The drain pipe 18 discharges the purified water in the purified water storage chamber 10 from the device. The second nozzles 16 eject reaction gas or other treatment liquids in the purified water storage chamber 10 and the reaction chamber 14 to further treat the sewage or disinfect the purified water, etc.

[0029] As Figures 1 to 7 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 setting, the air inlet pipe 23 serves as the inlet of the reaction gas, guiding the reaction gas into the rotating shaft 2.

[0030] As Figures 1 to 7As shown in the figure, 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 input pipe 37 is connected to the water distributor 36. In this setting, the vertical rod 33 is suspended and installed inside the housing 1 to provide support for the water distributor 36. The water distributor 36 evenly distributes the sewage transported by the sewage input pipe 37, enabling it to better enter the equipment for treatment. The sewage input pipe 37 guides the sewage into the equipment and is the inlet pipe for the sewage to enter the treatment process.

[0031] The implementation principle of a spray absorption treatment device supporting a distillation column in this embodiment is as follows: When treating sewage, the sewage flows into the water distributor 36 from the sewage input pipe 37. At the same time, the motor 22 is turned on. The output shaft 21 installed on the motor 22 drives the driving gear 20 to rotate. The driving gear 20 meshes with the driven gear 19, 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 evenly releases the sewage. During the operation of the device, the impurity cleaning mechanism starts to work. The filter plate 4 rotates together 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 a certain angle along with the support column 24 and the rotating shaft 2, the guide groove 25 on the support column 24 cooperates with the guide block 41 on the annular plate 26, enabling the annular plate 26 to slide upward along the guide rod 27. When the rotating plate 29 moves to the position of the ejector rod 34 along with the annular plate 26, the ejector rod 34 pushes the rotating plate 29 to rotate around the rotating shaft 28, driving the shovel plate 31 to flip through the guide plate 30. At this time, the torsion spring 42 is subjected to torsion. The cooperation between 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. Subsequently, the impurities will fall into the collector 35 through the guide plate 30, thus completing the impurity cleaning work. Immediately afterwards, the coordinated action of the guide groove 25 and the guide block 41 causes the annular plate 26 to move downward. During this process, the torsion spring 42 will drive the rotating plate 29 to rotate reversely around the rotating shaft 28. When the annular plate 26 touches the filter plate 4, all components are reset. 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, enters the gas storage chamber 8 through the through holes 12 on the rotating shaft 2, and is then sprayed out by a number of first nozzles 11 installed on the inclined plate 5. Since the inclined plate 5 rotates with the rotating shaft 2, it can not only make the sewage and the reaction gas fully mixed, but also make the sewage vibrate up and down, further promoting the reaction between the two. The first nozzles 11 are located on the inclined plate 5, and the reaction gas moves upward from below the sewage, greatly improving the sufficiency of the reaction. Subsequently, the sewage enters the reaction chamber 14 through the conveying pipeline 9. The second nozzles 16 in the reaction chamber 14 spray the reaction gas into it, reacting with the pretreated sewage again. After the sewage enters the reaction chamber 14, it will fall into the packing layer 13 for further reaction. 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 reaction chamber 14 for re-treatment. During this process, the water inlet pipe 40 guides the flushing water into the combined ring 38 and then into the flushing inclined pipes 39. A number of flushing inclined pipes 39 release the flushing water to different areas of the packing from different directions, impacting the packing from the inside, enabling the sewage and the reaction gas to continuously separate and absorb within the packing. Finally, the treated water falls onto the water collecting plate 17, flows into the purified water storage chamber 10, and is finally discharged from the device through the drain pipe 18.Each component operates in coordination to continuously carry out treatment processes such as impurity cleaning and spray reaction on the inflowing sewage, thereby achieving the purification of sewage. Through the mechanical linkage between components, this equipment realizes the efficient operation of sewage impurity cleaning and purification treatment, improving the efficiency and quality of sewage treatment.
