[0001] This application relates to the field of water treatment equipment technology, and in particular to a gravity-type air scrubbing filter device. Background Technology

[0002] Most current air scrubbing filters adopt a cylindrical design, which has the advantages of symmetrical structure and uniform stress distribution, but has the following problems: (1) Low space utilization: Circular equipment requires a large radial and vertical installation space, which is difficult to adapt to the limited space layout of existing factory buildings; (2) High installation complexity: When connecting the circular filter to the pipeline system, additional elbows or reducing parts are required, which increases the installation cost and is prone to uneven water flow or air resistance problems; (3) Inconvenient maintenance: The distribution of inspection ports in the circular filter is limited, and the internal inspection channels are narrow, making it difficult for personnel to operate and making it inconvenient to replace filter media and clean internally. Summary of the Invention

[0003] The technical problem this application aims to solve is: how to address the issues of low space utilization, complex installation, and inconvenient maintenance inherent in existing circular cylindrical designs.

[0004] To address the aforementioned technical problems, this application proposes a gravity-type air scrubbing filter device, comprising: The box body is a cuboid structure. The box body is provided with a plurality of spaced first partitions, and the plurality of first partitions divide the interior of the box body into a plurality of first chambers. Each first chamber includes, from top to bottom, a clear water chamber, a water-proof chamber and a water collection chamber. The water-proof chamber is provided with a filter material layer, and a filter plate is provided between the filter material layer and the water collection chamber. The first water inlet pipe is connected to the water-proof chamber; A first pipe connects the water collection tank and the clean water tank, and the first pipe is equipped with a water outlet pipe; The gas distribution pipe is located in the water collection tank.

[0005] More preferably, the gravity-type air scrubbing filter device further includes: A water distribution tank is located on the top of the tank body. The water distribution tank is provided with a plurality of spaced second partitions, which divide the water distribution tank into a plurality of water distribution chambers. The water distribution tank is also provided with a second water inlet pipe that communicates with the water distribution chambers. A water distribution pipe connects the water distribution chamber and the first water inlet pipe; The height of the second partition is lower than the depth of the water distribution tank.

[0006] More preferably, at least one of the second partitions is provided with an overflow cavity between itself and the wall of the water distribution tank, and the water distribution tank is also provided with a first overflow pipe communicating with the overflow cavity.

[0007] More preferably, the gravity-type air scrubbing filter device further includes a first drain pipe, which connects the water collection tank and the water outlet pipe.

[0008] More preferably, the gravity-type air scrubbing filter device further includes a second drain pipe, which is connected to the clean water tank.

[0014] Compared with the prior art, the gravity-type air scrubbing filter device proposed in this application has the following advantages: First, this application designs the housing as a cuboid structure, which can more closely fit the rectangular space layout of most factory buildings (especially existing ones), reducing ineffective gaps around the equipment. Compared to the larger radial and vertical installation space required by a circular cylinder, this design significantly improves space utilization efficiency and is easier to arrange or modify for installation in space-constrained sites. The cuboid structure facilitates connection with the pipeline system, which is usually arranged in a straight line or at right angles within the factory, reducing the number of elbows, reducers, and other fittings required for connection. This not only reduces installation complexity and cost but also helps maintain smooth and uniform water flow, reducing hydraulic losses or air resistance problems that may be caused by excessive pipe turns. In addition, the cuboid housing allows for more flexible arrangement of maintenance ports on the side walls, and the regular shape of the internal channels and chambers provides a more spacious and convenient operating space for personnel access, filter media replacement, internal cleaning, and component maintenance. Compared to the narrow internal maintenance channels and limited operation of circular filter tanks, this design greatly improves the convenience and safety of maintenance operations. Secondly, this application divides the box into multiple independent first chambers by setting a first partition, so that each first chamber can be equipped with an independent water and air distribution system, realizing compartment backwashing and maintenance, avoiding overall shutdown and improving usage efficiency.

[0027] Please refer to Figures 1-5 This application proposes a gravity-type air scrubbing filter device, including a housing 1, wherein the housing 1 has a cuboid structure. This allows the cuboid housing to fit more closely into the rectangular space layout of most factory buildings (especially existing ones), reducing ineffective gaps around the equipment. Compared to the larger radial and vertical installation space required by a cylindrical housing, this design significantly improves space utilization efficiency and is easier to arrange or modify in space-constrained sites. The cuboid structure facilitates connection with the typically straight or right-angled piping systems within the factory, reducing the number of connections required. The reduced number of required elbows, reducers, and other pipe fittings not only lowers installation complexity and cost but also helps maintain smooth and even water flow, minimizing hydraulic losses or air resistance caused by excessive pipe turns. Furthermore, the rectangular box allows for more flexible arrangement of maintenance ports on its side walls, and the regular shape of its internal channels and chambers provides a more spacious and convenient operating space for personnel access, filter media replacement, internal cleaning, and component maintenance. Compared to the narrow internal maintenance channels and limited operation of circular filter tanks, this design significantly improves the convenience and safety of maintenance operations.

[0028] In some embodiments, the gravity-type air scrubbing filter device further includes a first water inlet pipe 24, a first pipe 9, and an air distribution pipe 27; wherein, the housing 1 is provided with a plurality of spaced first partitions 14, and the plurality of first partitions 14 divide the interior of the housing 1 into a plurality of first chambers 15, each first chamber 15 including, from top to bottom, a clear water chamber 16, a water-separating chamber 17, and a water collection chamber 21, the water-separating chamber 17 is provided with a filter media layer 19, and a filter plate 20 is provided between the filter media layer 19 and the water collection chamber 21; thereby, by setting the first partitions 14, the interior of the housing 1 is divided into a plurality of independent first chambers 16. The chamber 15 allows each chamber to be equipped with an independent water and air distribution system, enabling separate backwashing and maintenance, and avoiding overall shutdown. The first water inlet pipe 24 is connected to the water-proof chamber 17. The first pipe 9 connects the water collection chamber 21 and the clear water chamber 16, and the first pipe 9 is equipped with an outlet pipe 10. The air distribution pipe 27 is located in the water collection chamber 21. Thus, sewage can enter the filter chamber 18 of the water-proof chamber 17 through the first water inlet pipe 24. Under the action of gravity, the water permeates the filter media layer 19 and enters the water collection chamber 21 through the filter head 28. The filtered water then enters the clear water chamber 16 through the first pipe 9.

[0029] In some embodiments, a first valve body 25 is provided on the first pipe 9, thereby enabling the first pipe 9 to be opened and closed.

[0030] In some embodiments, the side wall of the housing 1 is also provided with multiple inspection ports 13. At least one inspection port 13 is connected to the clear water chamber 16, at least one inspection port 13 is connected to the water-blocking chamber 17, and at least one inspection port 13 is connected to the water collection chamber 21. Thus, since the housing 1 is a cuboid structure with regular internal channels and chamber shapes, the installation of the inspection ports 13 provides a more spacious and convenient operating space for personnel entry, filter media replacement, internal cleaning, and component maintenance. Compared with the problem of narrow internal maintenance channels and limited operation in circular filter tanks, this design greatly improves the convenience and safety of maintenance operations. Moreover, the relatively regular side wall of the cuboid housing 1 is conducive to the installation and sealing of the inspection ports 13.

[0031] In some embodiments, to enable each first chamber 15 to be equipped with an independent water and air distribution system, the gravity-type air scrubbing filter device further includes a water distribution tank 2 and a water distribution pipe 8. The water distribution tank 2 is located at the top of the tank body 1, and the water distribution tank 2 is provided with multiple spaced second partitions 3, which divide the water distribution tank 2 into multiple water distribution chambers 4. The water distribution tank 2 is also provided with a second inlet pipe 6 that communicates with the water distribution chambers 4 and is connected to the sewage tank. The water distribution pipe 8 connects the water distribution chambers 4 and the first inlet pipe 24. In this way, each first chamber 15 can correspond to a water distribution chamber 4, thereby avoiding interference between two adjacent water and air distribution systems, and realizing compartment backwashing and maintenance. Moreover, the water distribution tank 2 is located at the top of the tank body 1, so that sewage can enter the filter chamber 18 of the water-proof chamber 17 through the first inlet pipe 24 under the action of gravity.

[0032] In some implementations, in order to ensure that the sewage can fill multiple water distribution chambers 4 after entering the water distribution tank 2 through the second inlet pipe 6, the height of the second partition 3 is limited to be lower than the depth of the water distribution tank 2, so that the sewage after one water distribution chamber 4 is filled can overflow into the adjacent water distribution chamber 4, thereby filling all multiple water distribution chambers 4 and ensuring that each independent water distribution and air distribution system can operate.

[0033] In some embodiments, in order to control the sewage in the water distribution chamber 4 from entering the water-blocking chamber 17, a fourth valve body 33 is provided on the first water inlet pipe 24.

[0034] In some embodiments, the water outlet pipe 10 is opened and closed, and for this purpose, a second valve body 30 is provided on the water outlet pipe 10.

[0035] In some embodiments, to prevent sewage from overflowing from the water distribution tank 2, at least one second partition 3 is provided between the tank wall of the water distribution tank 2 and the overflow chamber 5. The water distribution tank 2 is also provided with a first overflow pipe 7 that communicates with the overflow chamber 5, so that excess sewage can flow back to the sewage pool through the overflow chamber 5 and the first overflow pipe 7 to avoid polluting the factory.

[0036] In some embodiments, to facilitate the maintenance or replacement of filter media and filter plates in the water collection tank 21, the gravity-type air scrubbing filter device also includes a first drain pipe 11. The first drain pipe 11 connects the water collection tank 21 and the water outlet pipe 10, and a sixth valve body 39 is provided on the first drain pipe 11. When maintaining or replacing parts, the sixth valve body 39 is opened to connect the water collection tank 21 and the water outlet pipe 10, thereby draining the water in the water collection tank 21 through the first drain pipe 11, so that operators can enter the water collection tank 21 through the maintenance port 13.

[0037] In some embodiments, the gravity-type air scrubbing filter device further includes a second drain pipe 12, which is connected to the clear water tank 16. Specifically, the second drain pipe 12 is equipped with a seventh valve body 40. The function of the second drain pipe 12 is twofold: firstly, to drain the water in the clear water tank 16 so that operators can enter the clear water tank 16 through the inspection port 13; secondly, during the filtration and effluent stage, the second drain pipe 12 can be used to observe whether the effluent water quality meets the effluent requirements, thus preventing unqualified water from entering the subsequent product water tank and contaminating it.

[0038] In some embodiments, to prevent the water level in the clear water tank 16 from being too high, the gravity air scrubbing filter device also includes a second overflow pipe 23, which is connected to the clear water tank 16. When the water level in the clear water tank 16 reaches a set threshold, the excess water can be drained away through the second overflow pipe 23 to avoid affecting the normal operation of the overall equipment.

[0039] In some embodiments, a water collection pipe 29 is also provided inside the water collection tank 21. The water collection pipe 29 is connected to the first pipe 9 and is used to guide the water in the water collection tank 21 to the first pipe 9.

[0040] In some embodiments, the gravity-type air scrubbing filter device further includes a first drain pipe 31, which is connected to the first inlet pipe 24. Specifically, the first drain pipe 31 is provided with a third valve body 32. During the backwashing stage, the third valve body 32 is opened, and the water in the clear water tank 16 enters the water collection pipe 29 through the first pipe 9 and then enters the water collection tank 21. It then enters the filter media layer 19 through the filter head 28, thereby backwashing the filter media. The backwash water is discharged to the sludge discharge ditch 26 through the first inlet pipe 24 and the first drain pipe 31, and can be directly discharged or recycled.

[0041] In some embodiments, the gravity-type air scrubbing filter device further includes a first exhaust pipe 22, which is connected to the clear water tank 16, thereby enabling the air pressure in the clear water tank 16 to be adjusted through the first exhaust pipe 22 to ensure the normal operation of the filter.

[0042] In some embodiments, the filter media layer 19 comprises, from top to bottom, an activated carbon layer and a quartz sand layer. During the filtration stage, the upper activated carbon layer primarily functions as an adsorbent, efficiently removing organic matter, dissolved pollutants, odors, color, and some heavy metal ions from the water through chemical adsorption purification. The lower quartz sand layer primarily functions as a mechanical trapping layer, effectively filtering and trapping suspended particles, colloidal substances, and filter media abrasion debris (such as activated carbon powder) from the water through physical depth filtration. During the backwashing stage, because quartz sand has a higher density than activated carbon, the air-water mixture during backwashing (especially air scrubbing) more effectively fluidizes and rubs the lower quartz sand layer, washing away trapped impurities. Meanwhile, the upper activated carbon layer, due to its lower density, also expands and cleans well during backwashing, and the adsorbed pollutants are more easily desorbed under the intense air-water scouring, resulting in a more thorough cleaning.

[0043] In some embodiments, the filter plate 20 is provided with multiple filter heads 28 arranged in a matrix. During the filtration stage, water flows from top to bottom through the filter media layer 19. The matrix arrangement of the filter heads 28 ensures that the filtered clean water is collected uniformly and at equal flow rates across the entire plane area of ​​the filter plate, completely avoiding the phenomenon of excessively high or low local flow velocities. This ensures that the hydraulic load of the entire filter media layer 19 is consistent, all filter media are fully utilized, and "short circuits" or "dead zones" are prevented, thereby maximizing filtration efficiency and producing stable and uniform effluent. During the backwashing (air scrubbing) stage, the air distribution pipe 27 releases air into the water collection chamber 21. The air is sprayed upward through the filter heads 28 on the filter plate 20. The matrix arrangement ensures that the air is evenly distributed across the bottom plane of the entire filter media layer, forming a uniformly rising air bubble flow. The uniform airflow can fluidize and intensely rub the filter media (especially the lower layer of quartz sand), thereby completely stripping away the trapped impurities and discharging them with the backwash water. Uneven air distribution can lead to some areas not being properly rinsed, while other areas may experience filter media loss due to excessive airflow.

[0044] In some embodiments, to prevent excessive pressure in the first inlet pipe 24 during the backwashing stage, the gravity-type air scrubbing filter device further includes a second exhaust pipe 34, which is connected to the first inlet pipe 24. This allows gas in the water-blocking chamber 17 to be quickly discharged through the second exhaust pipe 34 during the air scrubbing stage, preventing pressure increase in the first inlet pipe 24. Specifically, the second exhaust pipe 34 is equipped with a fifth valve body 35 for controlling the opening and closing of the second exhaust pipe 34.

[0045] In some embodiments, the gravity-type air scrubbing filter device further includes an air inlet branch pipe 37 and an air inlet main pipe 38. The air inlet branch pipe 37 is used to connect the air inlet main pipe 38 and the air distribution pipe 27. The air inlet main pipe 38 is connected to a Roots blower. The Roots blower can compress air and deliver it to the air inlet branch pipe 37 through the air inlet main pipe 38, and finally enter the water collection tank 21 through the air distribution pipe 27. Furthermore, in order to control the opening and closing of the air inlet branch pipe 37, an air valve 36 is also provided on the air inlet branch pipe 37, so as to realize the independent backwashing of each first chamber 15, and the backwashing does not affect the working status of other normal first chambers 15.

[0046] The working process for this application is as follows: Please refer to Figures 1-5 ; Device startup: Open the fourth valve body 33, the first valve body 25 and the seventh valve body 40; Water is transported to the water distribution tank 2 through the second inlet pipe 6. The water in the water distribution chamber 4 then enters the first inlet pipe 24 through the water distribution pipe 8, and then enters the filter chamber 18 of the water isolation chamber 17. Under the action of gravity, the water permeates the filter media layer 19 and enters the water collection chamber 21 through the filter head 28. The filtered water then enters the clear water chamber 16 through the water collection pipe 29 and the first pipe 9, and then is discharged to the sludge discharge ditch 26 through the second drain pipe 12. Observe the water quality of the water outlet from the second drain pipe 12. When the water quality meets the requirements and is considered qualified water, close the seventh valve body 40 and open the second valve body 30. At this time, the qualified water in the clear water tank 16 enters the subsequent production water tank through the first pipe 9 and the outlet pipe 10, and the equipment enters the normal operation procedure.

[0047] It should be noted that the clean water tank 16 always contains a certain volume of clean water for use during backwashing.

[0048] Equipment shutdown: Close the fourth valve body 33, and then close the second valve body 30; After the equipment is shut down, the corresponding water level in filter chamber 18 should be maintained to enter the shutdown state, so as to facilitate backwashing of the equipment.

[0049] Equipment backwashing: Close the fourth valve body 33, the second valve body 30 and the first valve body 25; open the seventh valve body 40, and after no water flows out of the second drain pipe 12, close the seventh valve body (40). At this time, the clean water tank 16 still contains a certain volume of clean water. Open the air valve 36 and start the Roots blower. Air enters the air distribution area through the main air intake pipe 38, then enters the water collection chamber 21 through the air intake branch pipe 37 and the air distribution pipe 27, and then enters the filter media layer 19 through the filter head 28. The air agitates the filter media layer 19, thereby performing air scrubbing on the filter media. After the air scrubbing has been running for a period of time, the first valve body 25 and the third valve body 32 are opened. The water in the clear water tank 16 enters the water collection pipe 29 through the first pipe 9 and then enters the water collection tank 21. It then enters the filter media layer 19 through the filter head 28, thereby backwashing the filter media. The backwash water is discharged to the sludge discharge ditch 26 through the first water inlet pipe 24 and the first drain pipe 31. It can be discharged directly or recycled. When water flows out of the first drain pipe 31, close the air valve 36 and the Roots blower; when no water flows out of the first drain pipe 31 or when the drainage is observed to be clear, close the first valve body 25 and the third valve body 32, the backwashing procedure ends, and the equipment enters the standby state.

[0050] It should be noted that this application divides the interior of the housing 1 into multiple independent first chambers 15 by setting the first partition 14, so that each first chamber 15 can be equipped with an independent water and air distribution system, realizing compartment backwashing and maintenance, and avoiding overall shutdown.

[0051] In summary, the gravity-type air scrubbing filter device proposed in this application features a rectangular box structure 1, which can more closely fit the rectangular space layout of most factory buildings (especially existing ones), reducing ineffective gaps around the equipment. Compared to the larger radial and vertical installation space required by a circular cylindrical body, this design significantly improves space utilization efficiency and is easier to arrange or modify in space-constrained sites. The rectangular structure facilitates connection with the pipeline system, which is usually arranged in straight lines or right angles within the factory, reducing the number of elbows, reducers, and other fittings required for connection. This not only reduces installation complexity and cost but also helps maintain smooth and uniform water flow, reducing hydraulic losses or air resistance problems that may be caused by excessive pipeline turns. In addition, the rectangular box allows for more flexible arrangement of maintenance ports on the side walls, and the regular shape of the internal channels and chambers provides a more spacious and convenient operating space for personnel access, filter media replacement, internal cleaning, and component maintenance. Compared to the narrow internal maintenance channels and limited operation of circular filter tanks, this design greatly improves the convenience and safety of maintenance operations. In addition, this application divides the interior of the housing 1 into multiple independent first chambers 15 by setting a first partition 14, so that each first chamber 15 can be equipped with an independent water and air distribution system, realizing compartment backwashing and maintenance, and avoiding overall shutdown.
