Description

Technical Field

[0001] This utility model relates to the field of sewage odor extraction, specifically to a coarse grid odor extraction structure. Background Technology

[0002] During the wastewater treatment process, wastewater enters the wastewater pool inside the plant through the drainage pipe network. The wastewater is then filtered and treated by a coarse screen to remove sludge and debris. To prevent the emission of odors, an isolation cover is usually installed around the entire equipment. The isolation cover reduces the range of odor emission, thereby reducing the impact on the environment.

[0003] In the existing technology, the isolation enclosure is a closed and large space. The odor needs to be extracted and cleaned inside the isolation enclosure, which is relatively troublesome and not conducive to the entry and exit of personnel for inspection. In addition, due to the large temperature difference between the internal processing space and the outside, water vapor may form inside the isolation enclosure. Water vapor can easily corrode various equipment placed inside the isolation enclosure. If no intervention is taken, it may cause equipment to open circuit or short circuit. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing sewage odor extraction equipment is cumbersome to treat odors and is not conducive to staff entering and exiting for inspection; the water vapor escapes and easily corrodes the equipment, causing safety hazards. The purpose is to provide a coarse grid odor extraction structure, which solves the problems of low odor treatment efficiency and inability to avoid water vapor escape causing safety hazards in the existing sewage odor extraction equipment.

[0005] This utility model is achieved through the following technical solution:

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are for explanation only and are not intended to limit the scope of the utility model. The following specific examples illustrate the implementation of this utility model, and those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0028] This embodiment provides a coarse grid odor extraction structure, such as Figure 1 and Figure 2 As shown, it includes:

[0029] Wastewater tank 1 has vents circumferentially opened on its inner wall;

[0030] The suction assembly is located outside the sewage tank 1 and includes multiple first suction parts 3, each of which is connected to a corresponding exhaust port to suction odor.

[0031] In this embodiment, the sewage tank 1 has a square structure and stores sewage inside. The vent is located at the top of the sewage tank 1 and is higher than the sewage level. Multiple vents are provided circumferentially on the inner wall of the sewage tank 1, located at the front, rear, left, and right sides of the sewage tank 1, allowing odors and water vapor to pass through. Odors and water vapor can be discharged from the sewage tank 1 through the vents at different locations, thereby increasing the odor extraction range and improving extraction efficiency.

[0032] The first suction section 3 is provided in multiple ways and the number corresponds to the exhaust port. Specifically, each first suction section 3 includes a gas collection hood 31, a suction pipe 33 and a first fan 32. One end of the gas collection hood 31 is connected to the exhaust port and the other end is connected to the suction pipe 33. The first fan 32 is located inside the gas collection hood 31.

[0033] The specific process is as follows: Odor and water vapor are emitted from the surface of the sewage. The first blower 32 is turned on to suck them in. The first blower 32 creates a negative pressure inside the gas collection hood 31. Under the action of atmospheric pressure, the odor and water vapor enter the gas collection hood 31 through the exhaust port and are sucked into the blower. Finally, they enter the suction pipe 33 and are discharged outside the pool. The suction pipe 33 is connected to the exhaust system. After that, the sucked odor and water vapor enter the next treatment process.

[0034] In a specific implementation, such as Figure 1 As shown, each exhaust port includes multiple exhaust holes 2, which are arranged in an array. It is understood that in actual operation, the larger the area of ​​the exhaust port, the better the effect of odor extraction. However, with a larger exhaust port area, under the suction of the fan, tiny impurities in the sewage may enter the suction duct 33 along with the odor and water vapor, potentially hindering the fan's operation. After a period of use, the accumulation of impurities in the suction duct 33 will also reduce the flow rate of odor and water vapor.

[0035] Therefore, in this embodiment, the exhaust port is divided into multiple exhaust holes 2 for suction. On the one hand, it prevents tiny impurities from entering the gas collection hood 31, and on the other hand, it ensures the normal passage of odor and water vapor. At the same time, it ensures the area of ​​the exhaust port to ensure the efficiency of the final suction of odor.

[0036] In one specific embodiment, the diameter of the gas collecting hood 31 is larger than the diameter of the suction duct 33. Specifically, to ensure reliable connectivity, the diameter of the gas collecting hood 31 needs to match and connect with the exhaust port or multiple exhaust ports to prevent odor from escaping. However, to meet the odor extraction efficiency, the exhaust port area is large; therefore, the diameter of the gas collecting hood 31 is set larger than the diameter of the suction duct 33 to match the exhaust port or multiple exhaust holes 2.

[0037] In a specific implementation, such as Figure 1 and Figure 3 As shown, the sewage tank 1 is equipped with guide blocks 4 corresponding to the exhaust port positions. The guide blocks 4 are engaged within the sewage tank by positioning blocks 5. Specifically, four positioning blocks 5 are provided, positioned on the four sides of the guide blocks 4. The sewage tank 1 has positioning slots located above the exhaust port. When a positioning block 5 engages with its corresponding positioning slot, the positioning slot supports and limits the positioning block 5 and the entire guide block 4, thus fixing the guide block 4 to a certain extent.

[0038] In this embodiment, since the odor and water vapor rise upwards, the odor and water vapor near the exhaust port are easily drawn in. However, the odor and water vapor located in the middle of the sewage tank 1 are far away from each exhaust port and may directly escape from the sewage tank 1.

[0039] Based on this, this embodiment includes a guide block 4, which is a frustum shape, wider at the top and narrower at the bottom. The guide block 4 divides the sewage tank 1 into reasonable zones, with exhaust vents distributed in each zone. When odors and water vapor rise, the guide block 4 guides them into their respective zones. Due to the unique structure of the guide block 4, which is wider at the top and narrower at the bottom, the odors and water vapor gradually approach the exhaust vents of their respective zones as they rise, facilitating the suction process in each zone and ensuring its smooth operation. Additionally, water vapor may condense into droplets on the guide block 4, and these droplets, once condensed to a certain extent, fall back into the sewage tank 1, thus preventing the water vapor from evaporating outwards.

[0040] It should be noted that the guide block 4 is made of corrosion-resistant material, which can extend the service life of the guide block 4.

[0041] In addition, a handle is provided on the top of the guide block 4. When maintenance or replacement is required, the staff can lift the guide block 4 through the handle for easy operation.

[0042] In addition, the guide block 4 is located at the top of the sewage tank 1, which covers the sewage tank 1 to a certain extent, reduces the rate of odor and water vapor escape, and ensures that the first suction unit 3 has enough time to suction out the odor, thus ensuring the reliability and accuracy of odor suction.

[0043] In one specific embodiment, a bar screen 7 is installed on one side of the sewage tank 1, and a second suction section 6 is installed on the side of the guide block 4 near the bar screen 7. In this embodiment, the bar screen 7 is installed on the left side of the sewage tank 1. The bar screen 7 is used to intercept and remove suspended solids, debris, and sediment in the water; however, since the bar screen 7 requires a certain amount of space, setting an exhaust port on the left side of the sewage tank 1 does not effectively improve the suction effect.

[0044] Based on this, this embodiment includes a second suction unit 6. Specifically, the second suction unit 6 includes a gas collecting chamber 61, a second blower 62, and a gas collecting pipe 63. The gas collecting chamber 61 is installed on one side of the guide block 4, and an air inlet 64 is provided on the gas collecting chamber 61. The second blower 62 is located at the top of the gas collecting chamber 61. The gas collecting pipe 63 communicates with the gas collecting chamber 61. Similar to the guide block 4, the gas collecting chamber 61 is engaged in the sewage tank by a limiting block.

[0045] The specific working process is as follows: When the bar screen cleaner 7 is raised and lowered and drives the sludge and debris to rise, odor may be emitted from the sludge and debris. At this time, the second fan 62 is turned on. Under the attraction of the second fan 62, the odor enters the gas collection chamber 61 from the air inlet 64. The odor in the gas collection chamber 61 is drawn into the gas collection pipe 63 for discharge. Similar to the suction pipe 33, the gas collection pipe 63 is also connected to the exhaust system. After that, the odor and water vapor drawn in enter the next treatment process.

[0046] In one specific embodiment, the gas collection chamber 61 is wedge-shaped and cooperates with one side of the guide block 4. It can be understood that the guide block 4 divides the upper space of the sewage tank 1 into even sections. Since no exhaust port is opened on the left side, the gas collection chamber 61 cooperates with the left side of the guide block 4 to a certain extent, which can reduce the amount of odor emitted from the sewage tank 1 entering the left side space, and allow as much of the odor as possible to enter the right, front and rear spaces of the sewage tank 1.

[0047] In one specific embodiment, multiple air inlets 64 are provided, and the multiple air inlets 64 are arranged vertically on the air collection chamber 61.

[0048] As the bar screen cleaner 7 causes impurities to rise, the odor is emitted from different locations. Therefore, the air inlets 64 at different heights facilitate the suction of odor from different locations, thereby improving the suction effect.

[0049] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
