Description

Technical Field

[0001] This utility model relates to the field of deodorization technology, and in particular to a deodorization device for a sewage treatment pond. Background Technology

[0002] Wastewater treatment ponds are facilities used to physically, chemically, and biologically treat industrial or domestic wastewater to remove suspended solids, dissolved organic matter, and nutrients. The treatment process often produces malodorous gases such as hydrogen sulfide and ammonia. These gases not only affect the surrounding environment and residents' health but may also corrode equipment and reduce operational efficiency. Therefore, wastewater treatment ponds must be equipped with deodorization devices to ensure that emissions meet environmental standards and maintain a good working environment.

[0003] In existing technologies, odorous gases are prone to "short-circuiting" or "channeling" due to uneven distribution inside traditional fixed deodorization towers or biofilters. This causes most of the airflow to pass through only a local area, significantly reducing the effective contact area of ​​the packing material and resulting in low purification efficiency. Furthermore, under long-term operation, the surface of static packing layers is easily blocked or caked by high-concentration pollutants, which not only exacerbates system pressure drop and energy consumption but also creates anaerobic zones due to poor mass transfer, leading to decreased microbial activity and even failure. Therefore, we propose a deodorization device for wastewater treatment ponds to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a deodorization device for sewage treatment ponds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, a deodorization device for a sewage treatment pond is disclosed, including a base 1. Two deodorization boxes 2 are fixedly connected to the top of the base 1. The base 1 can stably support the two deodorization boxes 2 on the top, ensuring that the device remains stable during operation and avoiding positional displacement due to equipment vibration or external force. Two arc-shaped seats 3 are fixedly connected inside each of the two deodorization boxes 2. The arc-shaped seats 3 provide auxiliary support for the rotating outer stainless steel mesh 5, inner stainless steel mesh 6 and packing 7, reducing the deformation of the components due to gravity during rotation.

[0021] Both deodorizing boxes 2 have end plates 4 fixedly connected inside. The outer walls of both end plates 4 are fixedly connected with outer stainless steel mesh 5 and inner stainless steel mesh 6. The outer stainless steel mesh 5 and inner stainless steel mesh 6 have a certain thickness to prevent deformation. The two together form a cavity to accommodate the packing 7, which can fix the packing 7 to prevent it from falling off, and also ensure that the gas can pass through smoothly and contact the packing 7. The stainless steel material has good corrosion resistance and strength and can adapt to humid and corrosive gas environments.

[0022] A packing material 7 is placed between the outer stainless steel mesh 5 and the inner stainless steel mesh 6. The end plate 4 can rotate under the drive of the rotating component, which in turn drives the outer stainless steel mesh 5, the inner stainless steel mesh 6 and the packing material 7 to rotate, thereby enhancing the contact effect between the gas and the packing material 7.

[0023] The two deodorizing boxes 2 are connected by a connecting pipe 8. The outer walls of the two deodorizing boxes 2 are fixedly connected to a sealing door 9 by existing screws. The outer wall of the sealing door 9 is in contact with one end of the outer stainless steel mesh 5 and the inner stainless steel mesh 6. The sealing door 9 can seal the opening of the deodorizing box 2 to prevent the leakage of malodorous gas and ensure the circulation of gas in the closed space. At the same time, it is convenient to open it to replace or clean the internal filling material 7.

[0024] One of the sealing doors 9 has a circular tube 10 fixedly connected to its outer wall. Both ends of the circular tube 10 are sealed, preventing odor from entering. Multiple dispersion plates 11 are evenly fixedly connected to the outer wall of the circular tube 10. The multiple dispersion plates 11 are all located inside one of the inner stainless steel mesh 6. The multiple dispersion plates 11 can guide and divide the initially entering odorous gas, dispersing the gas into fine airflows, increasing the contact area with the purification medium such as the packing 7, and avoiding excessively high local gas concentrations that could affect the purification effect.

[0025] One of the deodorizing boxes 2 has a through hole on its outer wall. A T-shaped toothed ring 12 is rotatably connected to the inner wall of the through hole. One end of the T-shaped toothed ring 12 is fixedly connected to the outer wall of one of the end plates 4. A bearing is fixedly fitted on the outer wall of the T-shaped toothed ring 12. The outer ring of the bearing is fixedly connected to the outer wall of the deodorizing box 2. An air inlet pipe 13 is fixedly connected to the inner ring of the bearing. The bearing can rotate under the drive of the gear 15, which in turn drives the end plate 4, the outer stainless steel mesh 5, the inner stainless steel mesh 6 and the packing 7 to rotate. At the same time, the bearing and the bearing cooperate to ensure the stable connection of the air inlet pipe 13. One end of the air inlet pipe 13 extends to the odor generation point of the sewage treatment tank through the existing pipeline.

[0026] Both deodorizing boxes 2 have mounting holes on their outer walls. Spray pipes 17 are fixedly connected to the inner walls of the mounting holes. A water pump is fixedly connected to one end of the spray pipes 17. Drain pipes are fixedly connected to the outer walls of both deodorizing boxes 2. Atomizing nozzles 18 are evenly fixedly connected to the outer walls of the spray pipes 17. The atomizing nozzles 18 can atomize the purification liquid into fine droplets, increasing the contact area with the malodorous gas. Both deodorizing boxes 2 have lids 16 fixedly connected to their tops. An exhaust pipe 19 is fixedly connected to the top of one of the lids 16. A fan is fixedly connected to one end of the exhaust pipe 19. The fan draws out the purified gas by generating negative pressure.

[0027] The outer wall of the deodorizing box 2 is provided with a rotating assembly, which includes two stepper motors 14. The outer walls of both deodorizing boxes 2 are fixedly connected with support plates. The tops of the two support plates are fixedly connected to the outer walls of the two stepper motors 14 respectively. A gear 15 is fixedly sleeved on the outer wall of the output shaft of one of the stepper motors 14. The gear 15 is meshed with a T-shaped gear ring 12. One end of the output shaft of the other stepper motor 14 passes through the outer wall of the deodorizing box 2 and is fixedly connected to the outer wall of the other end plate 4.

[0028] Working principle: During use, the malodorous gas generated by the water treatment tank is introduced into one of the deodorization boxes 2 through the air inlet pipe 13. At this time, the T-shaped gear ring 12 connected to the air inlet pipe 13 through the bearing starts under the drive of the rotating component: one of the stepper motors 14 drives the gear 15 to rotate, and the gear 15 meshes with the T-shaped gear ring 12, thereby driving the end plate 4 connected to the T-shaped gear ring 12 to rotate synchronously; while the other stepper motor 14 drives the other end plate 4 connected to it to rotate. The rotation of the two end plates 4 drives the two sets of outer stainless steel mesh 5 and inner stainless steel mesh 6 to rotate, thereby driving the internal packing 7 to rotate. Multiple dispersion plates 11 are located inside the inner stainless steel mesh 6, which play a guiding and dividing role, increasing the contact area between the gas and the subsequent purification medium, and avoiding excessively high local gas concentration that affects the purification effect.

[0029] During the adsorption process, the spray pipe 17 introduces a purification liquid, such as deodorant solution or clean water, through a water pump connected to one end. The purification liquid is transported to the inside of the deodorization box 2 through the spray pipe 17 and forms fine droplets through the atomizing nozzles 18 evenly distributed on the outer wall. These droplets come into contact with the malodorous gas flowing through the packing 7 in the opposite or same direction. The atomized purification liquid can dissolve soluble malodorous components in the gas and wet the surface of the packing 7, thereby enhancing the adsorption capacity of the packing 7 for harmful substances.

[0030] The gas, after being initially purified by the first deodorization box 2, enters the second deodorization box 2 through the interconnection pipe 8 between the two deodorization boxes 2, repeating the above purification process of "dispersion, adsorption and spraying" to achieve secondary deep treatment, ensuring that the residual malodorous gas that has not been completely purified is further removed. The box cover 16 on the top of the two deodorization boxes 2 plays a sealing role to prevent gas leakage and ensure the airtightness of the purification process.

[0031] Finally, the clean gas, after two purification processes, is discharged through the exhaust pipe 19, completing the entire deodorization process. Throughout the process, the sealing door 9 comes into contact with the outer stainless steel mesh 5 and the inner stainless steel mesh 6, ensuring that the gas always circulates within the closed space, avoiding secondary pollution and ensuring smooth gas flow.

[0032] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the stepper motor 14, water pump, and fan to facilitate overall control. The stepper motor 14, water pump, and fan are connected to an external power source via cables.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
