Description

Technical Field

[0001] This invention relates to the field of water pollution control technology, specifically to an ion deodorization device used in the process of water pollution prevention and control. Background Technology

[0002] Wastewater pumping stations are an important component of wastewater systems. They are characterized by continuous, relatively small, but highly variable water flow and high levels of pollutants. Currently, wastewater pumping stations generate and emit foul-smelling exhaust gases. These gases primarily consist of volatile substances such as hydrogen sulfide, ammonia, and methanethiol, resulting in a comprehensive, pungent odor. These molecules diffuse in the air, corroding mechanical equipment, and when inhaled, they cause an extremely unpleasant odor sensation. To reduce the concentration of odors during the operation of wastewater pumping stations, plasma deodorization devices are commonly used for air purification. The main principle of plasma deodorization devices is the generation of a large number of positive and negative oxygen ions under a high-voltage electric field, which possess strong oxidizing properties. These ions can oxidize and decompose pollutants such as methanethiol, ammonia, hydrogen sulfide, ethers, and amines in a very short time, breaking the chemical bonds of volatile organic compounds and ultimately producing stable and harmless small molecules such as carbon dioxide and water, thereby purifying the air.

[0003] In related technologies, existing ion deodorization devices can effectively decompose odor molecules into harmless small molecules such as carbon dioxide and water in low-concentration odor environments, resulting in good purification effects. However, in high-concentration odor environments, the deodorization effect of the ion deodorization device will be affected. Moreover, existing ion deodorization devices usually require the equipment to be shut down when replacing and cleaning the filter plates, which is cumbersome and wastes working time.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] like Figures 1-10 As shown in the figure, this embodiment proposes an ion deodorization device for water pollution control, including a housing 1, a circulating air intake assembly 3, a filter assembly 4, and a power assembly 5. The housing 1 primarily serves for installation and support, and also isolates the internal components from the external environment. The circulating air intake assembly 3 mainly draws odorous gases generated from wastewater into the housing 1, where the ion deodorizer 2 deodorizes and purifies the gases. Additionally, it mixes some of the deodorized air with the undeodorized odorous gas inside the housing 1, thereby reducing the odor concentration and facilitating the deodorization work of the ion deodorizer 2. The filter assembly 4 primarily filters the air entering the housing 1, ensuring a suitable working environment for the ion deodorizer 2 and protecting it. The power assembly 5 primarily provides power to the circulating air intake assembly 3 and the filter assembly 4.

[0022] like Figures 1-3As shown, the housing 1 has a hollow internal structure, and air inlets 151 and air outlets 161 are respectively provided on opposite side walls of the housing 1. Multiple ion deodorizers 2 are installed inside the housing 1. Specifically, the housing 1 includes: a top plate 11 and a bottom plate 12 arranged opposite each other, a first side plate 13 and a second side plate 14 arranged opposite each other, and a front plate 15 and a rear plate 16 arranged opposite each other. The first side plate 13 and the second side plate 14 are both fixedly connected between the top plate 11 and the bottom plate 12. Thus, the top plate 11, the bottom plate 12, the first side plate 13, and the second side plate 14 can form a cuboid structure with openings at both ends and a hollow interior. The front plate 15 and the rear plate 16 are respectively fixedly connected to the openings at both ends to seal the openings. The air inlets 151 and the air outlets 161 are respectively opened on the front plate 15 and the rear plate 16. Multiple ion deodorizers 2 are installed on the top plate 11. It should be noted that both the air inlet 151 and the air outlet 161 can be circular structures. In addition, the ion deodorizer 2 is existing technology and consists of an ion generator, an ion transmission tube, and a control system.

[0023] In addition, such as Figure 1 , Figure 3 and Figure 5 As shown, the circulating air intake assembly 3 includes an air intake pipe 31, a circulation pipe 32, and a fan 33. The air intake pipe 31 can be fixedly connected inside the housing 1. Specifically, one end of the air intake pipe 31 can be fixedly connected to the front panel 15 and communicate with the air inlet 151. The fan 33 is fixedly connected inside the air intake pipe 31. When the fan 33 rotates, it can generate suction to draw air from outside the housing 1 into the housing 1, thereby facilitating subsequent purification work. One end of the circulation pipe 32 is connected to the air intake pipe 31, and the other end of the circulation pipe 32 extends to the outside of the housing 1 and communicates with the air outlet 161. One end of the circulation pipe 32 is provided with a first one-way valve 34 that flows towards the air intake pipe 31, that is, the air in the circulation pipe 32 can only flow into the air intake pipe 31. It should be noted that the diameter of the circulation pipe 32 is smaller than the diameter of the air intake pipe 31.

[0024] During use, the fan 33, by rotating, draws odorous air from outside the housing 1 into the housing 1. After being purified by the ion deodorizer 2, the odorous air flows out from the air outlet 161. It should be noted that, due to the faster airflow velocity inside the inlet duct 31, according to Bernoulli's principle, the pressure inside the inlet duct 31 near the circulation duct 32 is lower than the pressure inside the circulation duct 32. Therefore, some of the purified air at the air outlet 161 will enter the inlet duct 31 through the circulation duct 32, thereby diluting the odorous air inside the inlet duct 31 and thus better promoting the ion deodorizer 2's purification of the odor. It should also be noted that the other end of the circulation duct 32 can directly pass through the rear plate 16 and connect to the interior of the housing 1.

[0025] Furthermore, such as Figure 3 and Figure 6As shown, the filter assembly 4 includes a support frame 41, a circular filter plate 42, and a cleaning assembly 43. The support frame 41 is fixedly connected inside the housing 1, specifically, it is fixedly connected to the base plate 12. The filter plate 42 is rotatably connected to the support frame 41, meaning it can rotate relative to the support frame 41. The diameter of the filter plate 42 is larger than the diameter of the air inlet duct 31 and is eccentrically positioned relative to it. This eccentric positioning means that the axis of the filter plate 42 is parallel to but not collinear with the axis of the air inlet duct 31, and the filter plate 42 is fitted against the other end of the air inlet duct 31. This improves the sealing between the filter plate 42 and the air inlet duct 31, reducing odor leakage. The filter plate 42 has an annular filtration area, and different areas of the filtration area selectively cover the other end of the air inlet duct 31. The filter plate 42 can filter the air entering the housing 1 through the air inlet pipe 31, so as to prevent large particles from affecting the operation of the ion deodorizer 2, thereby enabling the ion deodorizer 2 to work better.

[0026] It should be noted that the radial length of the filter zone is greater than the direct diameter of the air inlet duct 31, ensuring that the filter zone completely covers the other end of the air inlet duct 31. During the rotation of the filter plate 42, different areas of the filter zone will alternately engage with the other end of the air inlet duct 31. This means that some filter holes on the filter plate 42 are always in operation, while others are inactive. This allows the cleaning component 43 to continuously clean the filter holes that switch from operation to inactivity, eliminating the need to replace the filter plate 42. Cleaning can be performed while the filter plate 42 is in operation, making it more convenient to use.

[0027] Furthermore, such as Figure 4 and Figure 6 As shown, the cleaning assembly 43 includes a cleaning shell 431 and brushes 434. The cleaning shell 431 is fixedly connected to the first side plate 13. The main structure of the cleaning shell 431 can be a fan-shaped structure, which can better adapt to the shape of the filtration area of ​​the filter plate 42. A cavity 432 is opened inside the cleaning shell 431, and the brushes 434 are fixedly connected inside the cavity 432. It should be noted that multiple brushes 434 are provided, and the brushes 434 can cooperate with the filter holes on the filter plate 42 to facilitate cleaning of the filter holes and the surface of the filter plate 42. In addition, in the rotation direction of the filter plate 42, the cleaning assembly 43 can be set close to the air inlet pipe 31, so that the filtration area can be quickly cleaned by the cleaning assembly 43 after being separated from the air inlet pipe 31, reducing the possibility of impurities falling into the shell 1, which is beneficial to the protection of the ion deodorizer 2.

[0028] like Figure 9 and Figure 10As shown, the cleaning housing 431 has a through hole 433 on the side facing the filter plate 42. Different areas of the filtration zone selectively enter the cavity 432 through the through hole 433 to cooperate with the brush 434. That is, a portion of the filtration zone is always present inside the cavity 432 through the through hole 433, allowing the brush 434 to clean the portion of the filtration zone inside the cavity 432. During the rotation of the filter plate 42, different areas of the filtration zone will cyclically enter the cavity 432, allowing the brush 434 to clean the entire filtration zone on the filter plate 42. This makes it more convenient to use, eliminating the need to remove the filter plate 42 for cleaning and saving time.

[0029] In addition, such as Figure 2 and Figure 7 As shown, a discharge pipe 435 is fixedly connected to the side of the cleaning shell 431 near the bottom plate 12. One end of the discharge pipe 435 communicates with the cavity 432, and the other end extends out of the shell 1 and communicates with the external space. The discharge pipe 435 is mainly used to discharge the impurities cleaned by the brush 434 to the outside of the shell 1, keeping the cleaning shell 431 and the inside of the shell 1 clean. Fixing the discharge pipe 435 to the side of the cleaning shell 431 near the bottom plate 12 is more reasonable because the cleaned impurities will fall into the bottom of the cavity 432 under the action of gravity, thus facilitating the direct discharge of impurities to the outside of the shell 1 through the discharge pipe 435.

[0030] In addition, such as Figure 3 and Figure 4 As shown, the power assembly 5 is housed within the housing 1 and provides power for the rotation of the fan 33 and the filter plate 42. Specifically, the power assembly 5 includes a motor 51, a drive shaft 52, a support base 53, a drive gear 54, a gear ring 55, and a pulley assembly 56. The motor 51 and the support base 53 are both fixedly connected to the base plate 12. The drive shaft 52 is rotatably connected to the support base 53, and one end of the drive shaft 52 is fixedly connected to the output end of the motor 51. The drive gear 54 is fixedly connected to the drive shaft 52. The gear ring 55 is fixedly connected to the circumferential outer wall of the filter plate 42 and is adapted to the drive gear 54. An clearance hole 311 is provided on the air inlet pipe 31, and the pulley assembly 56 passes through the clearance hole 311 and is simultaneously connected to the fan 33 and the drive shaft 52. It should be noted that the motor 51 can also be mounted on the support frame 41, depending on the actual working conditions. In addition, the pulley assembly 56 is connected to the fan 33 via a drive mechanism. The fan 33 mainly consists of a fan shaft and fan blades, and the pulley assembly 56 is connected to the fan shaft via a drive mechanism. Furthermore, the clearance hole 311 consists of two small holes, the size of which is the same as the cross-sectional size of the belt on the pulley assembly 56, which improves the sealing performance.

[0031] In use, starting the motor 51 drives the drive shaft 52 to rotate. The rotation of the drive shaft 52 simultaneously drives the pulley assembly 56 and the drive gear 54. The movement of the pulley assembly 56 drives the fan 33 to rotate, thereby drawing external odors into the housing 1 for purification. The rotation of the drive gear 54, in conjunction with the gear ring 55, drives the filter plate 42 to rotate, thus switching the working state of the filter holes in the filter area. This facilitates cleaning of the non-working areas of the filter area during the rotation of the filter plate 42, making it more convenient to use.

[0032] As an optional embodiment, such as Figure 7 and Figure 8 As shown, the discharge pipe 435 is inclined, and the distance from one end of the discharge pipe 435 to the base plate 12 is greater than the distance from the other end of the discharge pipe 435 to the base plate 12. That is to say, during use, the discharge pipe 435 is inclined downward. This setting is more reasonable, and impurities entering the discharge pipe 435 can slide out along the inner wall of the discharge pipe 435 under the action of gravity, which facilitates the discharge of impurities and reduces the occurrence of impurities clogging the discharge pipe 435.

[0033] As an optional embodiment, such as Figure 8 As shown, the cleaning assembly 43 also includes a suction pipe 436. One end of the suction pipe 436 is connected to the circulation pipe 32, and a second one-way valve 437 with the flow direction towards the circulation pipe 32 is provided at one end of the suction pipe 436. The other end of the suction pipe 436 is connected to the other end of the discharge pipe 435. That is to say, the air in the suction pipe 436 can only flow into the circulation pipe 32. It should be noted that the diameter of the suction pipe 436 is smaller than the diameter of the circulation pipe 32. According to Bernoulli's principle, when the air flows in the circulation pipe 32, the pressure in the suction pipe 436 is greater than the pressure in the circulation pipe 32. Therefore, the air in the suction pipe 436 will flow into the circulation pipe 32. Since the other end of the suction pipe 436 is connected to the other end of the discharge pipe 435, the suction pipe 436 will exert an attraction force on the impurities in the discharge pipe 435 at the other end of the discharge pipe 435, facilitating the discharge of impurities from the discharge pipe 435. It should be noted that the part connecting the other end of the suction pipe 436 to the discharge pipe 435 is set vertically, so that under the action of gravity, the slight suction will not cause impurities to enter the circulation pipe 32 from the suction pipe 436.

[0034] As an optional embodiment, such as Figure 9 and Figure 10 As shown, the wall of the through hole 433 is fitted to the filter plate 42. This improves the sealing between the cleaning housing 431 and the filter plate 42, thereby reducing the amount of impurities entering the housing 1 through the through hole 433 when the brush 434 cleans the filter plate 42, thus protecting the internal environment of the housing 1 and further protecting the ion deodorizer 2.

[0035] As an optional embodiment, the number of teeth on the drive gear 54 is less than the number of teeth on the gear ring 55. This can reduce speed. Since both the fan 33 and the filter plate 42 are driven by the drive shaft 52, the speed of the filter plate 42 can be reduced while ensuring that the fan 33 has a high speed. This reduces the impact of the rotation of the filter plate 42 on the airflow in the air inlet pipe 31, thereby allowing air to flow into the housing 1 more effectively through the filter plate 42.

[0036] As an optional embodiment, such as Figure 3 As shown, a transition pipe 6, concentric with the air inlet pipe 31, is fixedly connected to the support frame 41. The transition pipe 6 is located on the side of the filter plate 42 away from the air inlet pipe 31, and is fitted close to the filter plate 42. On the one hand, the transition pipe 6 can guide the air filtered by the filter plate 42; on the other hand, the air inlet pipe 31 and the transition pipe 6 can clamp the filter plate 42 in the middle, providing support for the filter plate 42 and allowing it to work more stably.

[0037] As an optional embodiment, such as Figure 8 As shown, a filter screen 7 is fixedly connected to the other end of the suction tube 436. The mesh diameter of the filter screen 7 is smaller than the filter hole diameter of the filter plate 42. The filter screen 7 mainly functions as a filter. By placing the filter screen 7 at the other end of the suction tube 436, impurities can be intercepted, preventing them from entering the circulation tube 32 through the suction tube 436.

[0038] As an optional embodiment, the diameter of the air inlet pipe 31 at the connection with the circulation pipe 32 is smaller than the diameter of the air inlet pipe 31 at other locations. This creates a more pronounced Bernoulli effect at the connection, thereby facilitating the generation of greater suction. Similarly, the diameter of the circulation pipe 32 at the connection with the suction pipe 436 is smaller than the diameter of the circulation pipe 32 at other locations, thus facilitating the generation of greater suction.

[0039] As an optional embodiment, two pipes are provided at the air outlet 161. One pipe is connected to the outside to discharge the purified air, and the other pipe is connected to the circulation pipe 32, which facilitates more air entering the circulation pipe 32.
