Description

Technical Field

[0001] This application relates to the field of waste gas treatment technology, specifically to a deodorization device. Background Technology

[0002] Deodorization equipment is an air purification device used to remove odors and eliminate unpleasant smells. Its structure is usually simple, and it features low energy consumption, high purification efficiency, and wide applicability, making it commonly used in factories, workshops, sewage treatment plants, and waste disposal sites. For treating exhaust gases, liquid absorption methods are often used; for treating wastewater, ion deodorization equipment is frequently employed; and for treating waste at recycling stations, spray deodorization equipment is commonly used.

[0003] Referring to Chinese patent application document CN118079634A, published on May 28, 2024, entitled "A High-Efficiency Spray Device for Deodorization in Waste Incineration", it includes a deodorization box, a spray assembly, and a flue gas diffusion assembly. The flue gas diffusion assembly diffuses the flue gas into the entire interior of the deodorization box, making the flue gas cover a wider area inside the deodorization box, so as to cooperate with the spray assembly to achieve high-efficiency spray treatment and improve the efficiency and quality of deodorization.

[0004] Referring to the above technical solutions, before atomizing and deodorizing odorous gases, a filter disc is often installed inside the deodorization box to remove large particles or odor sources from the gas, preventing these impurities from hindering or damaging subsequent treatment processes. However, with prolonged use, impurities tend to accumulate on the filter disc, reducing its filtration capacity and thus affecting the deodorization effect. Furthermore, when the accumulated impurities rot and deteriorate, they may release new gases or odors, causing secondary pollution and further reducing the overall effectiveness of the deodorization system. Summary of the Invention

[0005] In view of this, this application provides a deodorization device, mainly used to solve the problem that impurities accumulate in large quantities on the filter disc, affecting the subsequent deodorization effect.

[0006] To address the aforementioned technical problems, this application provides a deodorization device, comprising a deodorization box and an internal atomizing deodorization mechanism. The upper and lower ends of the deodorization box are connected to an air inlet pipe and an exhaust pipe, respectively. A hollow tube is rotatably connected through the middle of the deodorization box. A filter disc is fixedly fitted onto the outside of the hollow tube at the bottom of the inner cavity of the deodorization box. A slag collection trough is located below the filter disc at the bottom of the inner cavity of the deodorization box, and a slag discharge pipe connected to the bottom of the slag collection trough is connected to the inner cavity of the hollow tube via a rotary joint. A backflush pipe connects the exhaust pipe and the deodorization box to transfer impurities on the filter disc to the slag collection trough. A waste discharge pipe on the bottom support of the deodorization box is connected to the bottom of the inner cavity of the hollow tube via a rotary joint. Two baffles are provided at the top of the deodorization box, with a flow cavity for odorous gas to pass through between the two baffles. Multiple guide ports communicating with the flow cavity are provided on both baffles. A return port communicating with the flow cavity is provided at the top of the hollow tube. A drive assembly is provided on the bottom support of the deodorization box to drive the hollow tube to rotate.

[0007] By adopting the above technical solution, the filter disc can be backflushed with the help of the backflushing pipe, thereby cleaning the impurities accumulated on the filter disc. The baffle plate can capture the excess atomized droplets contained in the odor, and then these atomized droplets deodorize the impurities cleaned off the filter disc.

[0008] Optionally, both baffles are arranged in a conical shape, and the small-diameter end faces of the two baffles are arranged opposite to each other. Multiple guide ports are respectively opened in a circumferential array at the distal center of the lower baffle and the proximal center of the upper baffle.

[0009] By adopting the above technical solution, the contact area between the odor and the baffle plate can be increased, which is beneficial to the adhesion of atomized droplets on the outer surface of the baffle plate.

[0010] Optionally, the atomizing deodorization mechanism includes a spray pipe fixedly sleeved in the middle of the hollow tube, with atomizing nozzles provided at the spray nozzles evenly opened on the spray pipe, and a storage tank for storing deodorizing liquid provided on the wall of the deodorization box, and the liquid supply pipe of the storage tank is connected to the inner cavity of the spray pipe through a rotary joint.

[0011] By adopting the above technical solution, the spray pipe and atomizing nozzle can be used together to spray the deodorizing liquid into the odorous area in the form of atomized droplets.

[0012] Optionally, the drive assembly includes a servo motor mounted on the bottom support of the deodorizing box, which can drive the hollow tube to rotate via gear transmission.

[0013] By adopting the above technical solution, when the servo motor drives the hollow tube to rotate, the filter disc and the spray pipe can rotate together, thereby improving the filtration effect of the filter disc and the uniformity of the atomized droplet spray.

[0014] Optionally, the hollow tube has multiple baffles arranged in an array in the middle of its outer surface. When the baffles rotate with the hollow tube, they can turbulent the rising odor.

[0015] By adopting the above technical solution, the rising odor can be turbulently mixed, thereby enabling the odor to react more effectively with the atomized droplets.

[0016] Optionally, both baffles are rotatably connected and fitted onto the outside of the hollow tube, and a vibration mechanism is provided inside the hollow tube to shake off the deodorizing liquid adhering to the outer surface of the baffles.

[0017] Optionally, the vibration mechanism includes a support seat rotatably connected between the bottom bracket of the deodorizing box and the bottom end of the hollow tube. A counterweight rod located in the inner cavity of the hollow tube is radially slidably connected between the support seat and the hollow tube via an elastic element. A transmission assembly for driving the support seat to rotate is provided between the support seat and the hollow tube.

[0018] By adopting the above technical solution, the vibration generated by the counterweight rod can cause the deodorizing liquid attached to the outer surface of the baffle to flow together.

[0019] Optionally, the transmission assembly includes bevel gears respectively mounted on the support seat and the hollow tube, and a reversing gear mounted on the bottom bracket of the deodorizing box, with both bevel gears simultaneously meshing with the reversing gear.

[0020] By adopting the above technical solution, the bearing seat can rotate together with the hollow tube through the cooperation of two bevel gears and reversing gear.

[0021] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0022] 1. The backflushing method is used to clean the filter disc in a timely manner during the deodorization process, reducing the probability of impurities accumulating excessively on the filter disc and affecting the deodorization effect. It can also capture and collect excess atomized droplets in the odor, and the collected atomized droplets deodorize the impurities cleaned off the filter disc, improving the comprehensiveness of the deodorization work.

[0023] 2. By adding a vibration mechanism, the atomized droplets can be mixed and stirred with the impurities cleaned from the filter plate while improving the atomized droplet convergence efficiency, so that the two can react fully and thus improve the final quality of deodorization.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will be combined with the embodiments of this application. Figures 1-5 The technical solutions of the embodiments of this application are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this application are within the scope of protection of this application.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This embodiment provides a deodorization device, including a deodorization box 1, a hollow tube 3, a filter disc 4, an atomizing deodorization mechanism 2, a backflushing assembly, a reflux assembly, and a drive assembly 7. The deodorization box 1 has an inlet pipe 11 and an exhaust pipe 12 connected to its upper and lower ends, respectively. The hollow tube 3 is rotatably connected and runs through the middle of the deodorization box 1. The filter disc 4 is fixedly sleeved on the outside of the hollow tube 3 and located at the bottom of the inner cavity of the deodorization box 1. The drive assembly 7 includes a servo motor 71 mounted on a support at the bottom of the deodorization box 1. The servo motor 71 can drive the hollow tube 3 to rotate via gear transmission.

[0032] Among them, reference Figure 1 and Figure 2The atomizing deodorizing mechanism 2 includes a spray pipe 21, an atomizing nozzle 22, and a storage tank 23. The spray pipe 21 is fixedly sleeved in the middle of the hollow tube 3. The atomizing nozzle 22 is provided with multiple nozzles that are connected to spray openings evenly distributed on the spray pipe 21. The storage tank 23 is installed on the wall of the deodorizing box 1. The storage tank 23 is used to store deodorizing liquid, and the liquid supply pipe of the storage tank 23 is connected to the inner cavity of the spray pipe 21 through a rotary joint.

[0033] After the odorous gas is introduced into the deodorizing box 1 through the air inlet pipe 11, the filter plate 4 can filter out the impurities inside the odorous gas. Then the odorous gas continues to rise. At this time, the deodorizing liquid inside the storage tank 23 passes through the spray pipe 21 and the atomizing nozzle 22 in sequence and is sprayed into the odorous gas in the form of atomized droplets to complete the deodorization work. In this process, the hollow tube 3 is rotated by the cooperation of the servo motor 71, which drives the filter plate 4 and the spray pipe 21 to rotate together, thereby improving the filtration effect of the filter plate 4 and the uniformity of the atomized droplet spray.

[0034] Among them, reference Figure 2 , Figure 3 and Figure 5 The backflushing assembly includes a slag collection tank 5, a backflushing pipe 51, and a waste discharge pipe 52. The slag collection tank 5 is located at the bottom of the inner cavity of the deodorizing box 1 and below the filter plate 4. The slag discharge pipe 53 connected to the bottom of the slag collection tank 5 is connected to the inner cavity of the hollow tube 3 through a rotary joint. The backflushing pipe 51 is connected between the diversion port in the middle of the exhaust pipe 12 and the backflushing port at the bottom of the deodorizing box 1, and is used to transfer impurities on the filter plate 4 to the inside of the slag collection tank 5. The waste discharge pipe 52 is set on the bottom support of the deodorizing box 1, and the waste discharge pipe 52 is connected to the bottom of the inner cavity of the hollow tube 3 through a rotary joint.

[0035] When the odor has been deodorized and enters the next treatment equipment through the exhaust pipe 12, some of the odor will enter the bottom of the inner cavity of the deodorization box 1 through the backflush pipe 51 and backflush the filter plate 4. Since the backflush pipe 51 and the slag collection tank 5 are located on the same circumferential position of the deodorization box 1, the backflush pipe 51 can blow off the impurities on the inner arc wall of the filter plate 4. As the filter plate 4 rotates, all the impurities on the inner arc wall of the filter plate 4 will eventually be concentrated in the slag collection tank 5. Then the impurities in the slag collection tank 5 will be discharged through the slag discharge pipe 53, the hollow pipe 3 and the waste discharge pipe 52 in sequence. (During this process, since the odor supplied into the slag collection tank 5 by the backflush pipe 51 is the treated gas, the odor entering the slag collection tank 5 can carry the impurities in the slag collection tank 5 together and be discharged directly through the slag discharge pipe 53, the hollow pipe 3 and the waste discharge pipe 52, or re-enter the deodorization box 1 through the filter holes on the filter plate 4 that are not directly corresponding to the backflush pipe 51 for circulation).

[0036] Among them, reference Figure 2 and Figure 3The reflux assembly includes two baffles 6, a flow chamber 61, a guide port 62, and a reflux port 63. Both baffles 6 are located at the top of the deodorizing box 1. The flow chamber 61 is located between the two baffles 6 and allows odorous gases to pass through. Multiple guide ports 62 are provided and respectively opened on the two baffles 6, used to connect the inner cavity of the deodorizing box 1 with the flow chamber 61. The reflux port 63 is opened at the top of the hollow tube 3 and can communicate with the flow chamber 61.

[0037] As the odorous gas reacts with the atomized droplets to complete deodorization and continues to rise, the odorous gas will pass sequentially through the guide port 62 on the lower baffle plate 6, the flow cavity 61, and the guide port 62 on the upper baffle plate 6. At this time, the excess atomized droplets contained in the odorous gas will adhere to the outer surface of the two baffle plates 6. As the atomized droplets converge, these atomized droplets will be transformed back into the form of deodorizing liquid and enter the hollow tube 3 through the return port 63. Therefore, when the impurities inside the slag collection tank 5 enter the hollow tube 3, they will react with the deodorizing liquid transformed by the atomized droplets, thereby improving the comprehensiveness of the deodorization work.

[0038] Additionally, refer to Figure 2 and Figure 3 Both baffles 6 are cone-shaped, and the small-diameter end faces of the two baffles 6 are opposite to each other. Multiple guide ports 62 are respectively opened in a circumferential array at the distal center of the lower baffle 6 and the proximal center of the upper baffle 6.

[0039] By restricting the shape of the baffle 6, the contact area between the odor and the baffle 6 can be increased, which is beneficial for the adhesion of atomized droplets on the outer surface of the baffle 6.

[0040] Reference Figure 2 Multiple turbulence blades 31 are arrayed in the middle of the outer surface of the hollow tube 3. When the turbulence blades 31 rotate with the hollow tube 3, they can turbulent the rising odor.

[0041] During the rotation of the hollow tube 3, the turbulence blades 31 can turbulently mix the rising odor, thereby enabling the odor to react more effectively with the atomized droplets.

[0042] Reference Figure 2 , Figure 3 and Figure 4Two baffles 6 are rotatably connected and fitted onto the outside of the hollow tube 3. A vibration mechanism 8 is installed inside the hollow tube 3 to shake off the deodorizing liquid adhering to the outer surface of the baffles 6. The vibration mechanism 8 includes a support 81, a counterweight 82, an elastic element 83, and a transmission assembly 84. The support 81 is rotatably connected between the bottom support of the deodorizing box 1 and the bottom end of the hollow tube 3. The counterweight 82 is radially slidably connected between the support 81 and the hollow tube 3 through the elastic element 83, and the counterweight 82 is located in the inner cavity of the hollow tube 3. The transmission assembly 84 includes two bevel gears 841 and a reversing gear 842. The two bevel gears 841 are respectively mounted on the support 81 and the hollow tube 3, and the reversing gear 842 is mounted on the bottom support of the deodorizing box 1. The two bevel gears 841 are simultaneously meshed with the reversing gear 842.

[0043] During the rotation of the hollow tube 3, the bearing seat 81 can rotate accordingly through the cooperation of the transmission component 84. At this time, the counterweight rod 82 can vibrate under the action of centrifugal force and elastic element 83. When the vibration is transmitted from the hollow tube 3 to the baffle plate 6, it can promote the convergence of the deodorizing liquid attached to the outer surface of the baffle plate 6. When the counterweight rod 82 moves inside the hollow tube 3, it can generate a certain degree of stirring effect on the impurities after backflushing and the deodorizing liquid converted from atomized droplets, which is conducive to the efficient reaction of the two.

[0044] The implementation principle of a deodorization device according to an embodiment of this application is as follows:

[0045] When the odor enters the deodorizing chamber 1 through the air inlet pipe 11, it first comes into contact with the filter disc 4. The filter disc 4 intercepts and filters out various solid impurities carried in the odor. Then, the odor continues to flow upward. At this time, the deodorizing liquid stored in the storage tank 23 is transferred to the atomizing nozzle 22 through the spray pipe 21. The atomizing nozzle 22 then transforms it into fine atomized droplets and sprays them evenly onto the rising odor. These atomized droplets can fully contact the odor and adsorb the odor components in the odor, thus completing the deodorization process. At the same time, the servo motor 71 drives the hollow tube 3 to rotate, which drives the filter disc 4 and the spray pipe 21 to rotate synchronously, thereby improving the filtration effect of the filter disc 4. At the same time, the rotating spray pipe 21 can drive the atomizing nozzle 22 to form a dynamic spray range, which greatly increases the contact area between the atomized droplets and the odor, ensuring a more uniform distribution of the deodorizing liquid and improving the thoroughness of odor removal.

[0046] When the odorous gas completes the deodorization process and enters the next stage of treatment equipment through the exhaust pipe 12, some of the odorous gas will be guided to the bottom of the inner cavity of the deodorization box 1 through the backflush pipe 51, forming a reverse blowing force on the filter disc 4, thereby removing the impurities accumulated on the inner arc wall of the filter disc 4 and preventing the filter holes from clogging. At the same time, with the continuous rotation of the filter disc 4, the blown-off impurities will be concentrated in the slag collection tank 5. Finally, the impurities collected in the slag collection tank 5 will enter the hollow pipe 3 along the slag discharge pipe 53, and then be discharged through the waste discharge pipe 52 connected to the hollow pipe 3.

[0047] Furthermore, as the odorous gas continues to rise after deodorization, it passes sequentially through the guide port 62 on the lower baffle plate 6, the flow cavity 61, and the guide port 62 on the upper baffle plate 6. The special structure of the baffle plate 6 forces the odorous gas to change its flow direction, causing excess atomized droplets within the odorous gas to adhere to the outer surfaces of the two baffle plates 6. As the atomized droplets continuously converge, they transform back into deodorizing liquid and enter the hollow tube 3 through the return port 63. Therefore, when impurities inside the slag collection tank 5 enter the hollow tube 3, these impurities react with the deodorizing liquid transformed from the atomized droplets. This not only achieves the recycling of the deodorizing liquid but also provides secondary treatment for any residual odor components in the impurities, thereby comprehensively improving the purification effect of the entire deodorization system.

[0048] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
