Description

Technical Field

[0001] This invention belongs to the field of water treatment technology, including tap water purification, sewage treatment, and chemical industry. Specifically, it relates to a sedimentation treatment device in water treatment equipment, particularly a side-flow shallow pool sedimentation device, and more specifically, it discloses a distributed uniform water intake method and system in a side-flow shallow pool sedimentation device. Background Technology

[0002] The working principle and existing problems of the existing technology "lateral flow shallow pool sedimentation device":

[0003] In the existing technology, the "lateral flow shallow pool sedimentation device" consists of an inlet zone 1, a lateral flow shallow pool sedimentation module 2, a sludge collection tank 3, and an overflow water intake device 5; the overflow water intake device is further composed of a flow-stabilizing perforated wall 5.1, an overflow triangular weir water collection trough 5.2, and an outlet pipe 5.3, see [reference needed]. Figure 1 As shown.

[0004] In the side-flow shallow pool sedimentation process, the final step is to collect and extract the purified water after it has been treated by the side-flow shallow pool sedimentation module 2.

[0005] Existing water intake and collection methods primarily employ an overflow-type triangular weir collection trough. The main problem with this method is uneven water intake. At the outlet of the lateral flow shallow sedimentation module, the closer to the triangular weir intake, the greater the water intake; however, as the depth from the intake increases, the water intake gradually decreases. Although a flow-stabilizing perforated wall or a flow-rectifying plate is incorporated into the sedimentation device, the problem of uneven water intake at the outlet of the lateral flow shallow sedimentation module remains unresolved.

[0006] A side-flow shallow sedimentation tank module can be considered as consisting of multiple stacked horizontal pipes. At the outlet of these horizontal pipes, the water pressure increases with increasing water depth. For example, if the sedimentation module is 3m high, the water pressure increases from 0 to 0.03 MPa at -3m. The characteristic of the overflow-type triangular weir water intake method is that "due to the water level difference, the water intake at the outlet of the horizontal pipe gradually decreases with increasing water depth." This results in different water intake volumes at different water depths, meaning different water flow velocities within the horizontal pipe at different depths—faster at higher intake volumes and slower at lower intake volumes. Since water flow velocity is a crucial technical parameter in sedimentation treatment, changes in this parameter are a major cause of ineffective mud-water separation and decreased sedimentation quality. Therefore, the overflow-type triangular weir water intake method is unsuitable for use in side-flow shallow sedimentation tanks and urgently needs to be addressed. Summary of the Invention

[0007] This invention provides a distributed uniform water intake method and system for a lateral flow shallow pool sedimentation device, which aims to solve the technical problem of "uneven water intake" at the outlet of the lateral flow shallow pool sedimentation module in the prior art.

[0008] The technical solution of this invention is implemented as follows:

[0009] A distributed uniform water intake system in a lateral flow shallow sedimentation tank includes a water intake device; characterized in that,

[0010] In the pool behind the lateral flow shallow sedimentation module 2, a water intake device 4 is installed; the water intake device 4 includes: a water intake bell mouth 4.1, a partition wall 4.2, a water collection pipe or water collection trough 4.3, a water collection inlet pipe 4.4, and a water intake connecting pipe 4.5; behind the outlet of the lateral flow shallow sedimentation module 2, and at certain intervals, a clean water intake level is provided, which is composed of several large bell mouths of water intake bell mouths 4.1 and is parallel to the outlet section of the lateral flow shallow sedimentation module; a partition wall 4.2 is vertically installed behind the clean water intake level to isolate the pool water; behind the partition wall is a waterless area; a water collection pipe or water collection trough 4.3 is installed above the waterless area and not higher than the water level line of the upper part of the lateral flow shallow sedimentation module 2;

[0011] The water intake plane is evenly divided into several small grid areas. For each small area, a water intake funnel 4.1 is installed to introduce the purified water discharged from the lateral flow shallow pool sedimentation module. The rear end of each water intake funnel is installed at the starting end of its respective water intake connecting pipe 4.5. Multiple water intake connecting pipes first pass horizontally through the partition wall 4.2 and then extend upwards, so that their ends are connected one-to-one to one end of several water collection inlet pipes 4.4 installed above the central axis of the water collection pipe or water collection tank 4.3. One or both ends of the water collection inlet pipes 4.4 are connected one-to-one to the ends of different water intake connecting pipes 4.5. The several water collection inlet pipes 4.4 above the central axis of the water collection pipe or water collection tank 4.3 are all arranged at the same horizontal level, side-by-side, and have the same pipe diameter, so that the outlet water pressure and outlet flow of each water intake connecting pipe 4.5 are the same.

[0012] The water inlet pipe 4.4 has its lower half-pipe removed from the inside of the water collection pipe or water collection tank 4.3, forming a half-pipe with an open lower end. Water from the water intake pipes at both ends can fall into the water collection pipe or water collection tank 4.3 through the opening at the removed half-pipe.

[0013] The distributed uniform water intake system in the lateral flow shallow pool sedimentation device is described above, wherein each of the small areas is rectangular in shape, with a lateral dimension b not greater than 600 mm and a longitudinal dimension h not greater than 400 mm.

[0014] The distributed uniform water intake system in the lateral flow shallow pool sedimentation device is described above. The water intake flare 4.1 is composed of a rectangular flare A, a square-to-round transition section C, and a round pipe connector D connected sequentially. The rectangular flare A has a frustum-shaped structure, with a large flare at the front and a small flare at the rear. The large flare has a lateral dimension not exceeding 580mm and a longitudinal dimension not exceeding 380mm. Multiple uniform water intake partition plates B are installed inside the rectangular flare A, dividing the interior into nine independent water intake channels. These channels form a nine-square grid of water intake points at both ends of the flare. One end of the square-to-round transition section C is square, and the other end is round. The small flare connects to the square end, and the round end connects to the round pipe connector D.

[0015] The distributed uniform water intake system in the lateral flow shallow pool sedimentation device is described above, wherein the wall of the connecting pipe is sealed with the partition wall, and a pipe joint for connecting to the water intake funnel 4.1 is provided on the inner side of the partition wall.

[0016] The distributed uniform water intake system in a lateral flow shallow pool sedimentation device includes a water collection pipe or water collection trough 4.3 with multiple horizontal and coaxial mounting holes for inserting and fixing the water collection inlet pipe 4.4 at approximately 45° above its horizontal axis. The hole diameter is DN80. The number of holes is as follows: when the sedimentation module height H = 1500 mm, the water collection pipe or water collection trough 4.3 has 2 sets of mounting holes every 600 mm; when the sedimentation module height H = 3000 mm, the water collection pipe or water collection trough 4.3 has 4 sets of mounting holes every 600 mm. Each set of mounting holes includes two mounting holes facing each other, with a water collection inlet pipe 4.4 installed between them. A pipe joint connecting the water collection inlet pipe 4.4 and the connecting pipe is provided outside the mounting holes.

[0017] A distributed uniform water intake method in a lateral flow shallow pool sedimentation device, wherein the purified water output from the lateral flow shallow pool sedimentation module 2 is drawn from a purified water intake surface set in the pool behind it. The purified water intake surface is uniformly divided into several small grid areas, and several water intake bell-shaped openings 4.1 are correspondingly set to connect the water intake pipes to draw water from the pool. Each connecting pipe passes through the partition wall in the pool and enters a waterless area, delivering the purified water to several corresponding water collection inlet pipes. Each water collection inlet pipe is set at the same horizontal level and arranged side by side. The pipes are arranged in parallel with the same diameter to ensure that the water pressure and flow rate of each water intake connecting pipe 4.5, the water intake flow rate of the corresponding water intake funnel, and the water intake flow rate of the lateral flow shallow pool sedimentation module outlet and its corresponding small area are all the same. Several water collection inlet pipes are set in the water collection pipe or water collection tank 4.3 and can be connected to the connecting pipes at both ends for water intake. The half-pipe below the central axis of the water collection inlet pipe is removed to form a half-pipe with an open bottom. The water coming in from the water intake connecting pipes connected at both ends falls into the water collection pipe or water collection tank 4.3 through the opening at the removed half-pipe to complete the water intake.

[0018] The method for distributed uniform water intake in a lateral flow shallow pool sedimentation device, wherein the water inlet pipe is installed on a coaxial mounting hole on the left and right pipe walls at a position approximately 45° above the horizontal axis of the water collection pipe or water collection tank 4.3.

[0019] The working principle and features of this invention are as follows:

[0020] In the side-flow shallow pool sedimentation process, the final step is to collect and extract the purified water after it has been treated by the side-flow shallow pool sedimentation module 2.

[0021] Current water intake and collection methods primarily employ an overflow-type triangular weir collection trough. The main problem with this method is uneven water intake at the outlet of the lateral flow shallow sedimentation module. The closer to the triangular weir, the larger the water intake; conversely, the water intake gradually decreases with increasing depth. This phenomenon is directly related to the pressure differences at different water depths; as water depth increases, water pressure gradually increases, and the water intake gradually decreases. This variation in water intake directly affects the crucial technical parameter of "water flow velocity" in the sedimentation process, thus directly impacting the quality of the treated effluent.

[0022] To address the problem of uneven water intake at the outlet of the lateral flow shallow pool sedimentation module in the existing technology, the present invention virtually divides the cross-section at the outlet of the sedimentation module into several small grid areas. The preferred scheme for each small area is: lateral dimension b = 600 mm; longitudinal dimension h = 400 mm; a water intake flare 4.1 is set in each small area; the water intake flare is installed at the starting end of the water intake connecting pipe 4.5; the water intake connecting pipe passes through the partition wall 4.2, and its end is connected to the water inlet pipe 4.4 above the central axis of the water collection pipe or water collection tank 4.3.

[0023] Because the water inlet pipes 4.4 above the central axis of the water collection pipe or water collection tank 4.3 are all on the same horizontal plane and have the same diameter, the water pressure and flow rate of each water intake connecting pipe 4.5 are the same. Based on this principle, water in each small area at the outlet of the lateral flow shallow pool sedimentation module can be taken out evenly and in equal amounts. This ensures that each horizontal pipe at different water depths can operate according to the designed technical parameters, thereby obtaining a high-quality sedimentation effect that matches the design. This eliminates the drawbacks of existing technologies that use overflow water intake methods, which cannot uniformly extract water and result in poor sedimentation effects.

[0024] The structure and features of the water intake funnel 4.1 of this invention:

[0025] The water intake flare is a thin-shell structure, a horizontally placed square-shaped flare with a rounded top and bottom. The rear end is a round pipe connector that connects to the starting end of the water intake connecting pipe 4.5. The front end of the flare is rectangular, preferably with a horizontal dimension of 580mm and a vertical dimension of 380mm. The rear end of the flare, connecting to the round pipe connector, is round, preferably with a DN80 diameter. The flare angle is ≤60°. To ensure uniform water intake within each flare area, horizontal and vertical uniform water intake partitions are installed inside the flare. The preferred solution is: "The rectangular flare is divided into a reduced 9-grid structure using uniform water intake partitions."

[0026] The structure and features of the partition wall 4.2 of this invention:

[0027] The partition wall serves to separate the sedimentation tank from the water collection pipe or water collection trough 4.3; on the partition wall 4.2, a through-wall water intake connecting pipe 4.5 is installed on the wall according to the number and position of the water intake bell mouth 4.1. The outer wall of the connecting pipe is sealed with the wall, and a pipe joint for connecting to the water intake bell mouth 4.1 is left on the inner side of the partition wall.

[0028] Structure and characteristics of the water collection pipe or tank 4.3: The water collection pipe or tank 4.3 is a pipe or tank for collecting purified water after sedimentation treatment; a horizontal hole is made at approximately 45° above the horizontal axis of the water collection pipe, with the holes on the left and right pipe walls being coaxial. Preferred option: hole diameter DN80; Number of holes: Preferred option: when the sedimentation module height H = 1500mm, the water collection pipe or tank 4.3 has 2 sets of holes every 600mm of length. When the sedimentation module height H = 3000mm, the water collection pipe or tank 4.3 has 4 sets of holes every 600mm of length.

[0029] Structure and features of the water inlet pipe 4.4: The lower half of the pipe, below the central axis and inside the water collection pipe or water collection tank 4.3, is removed. After inserting the water inlet pipe 4.4 into the opening of the water collection pipe or water collection tank 4.3, the left and right ends of the pipe are respectively connected to the water intake connecting pipes 4.5, allowing water to enter from both sides.

[0030] The beneficial effects of this invention are:

[0031] Because the water inlet pipes 4.4 above the central axis of the water collection pipe or water collection tank 4.3 are all on the same horizontal plane and have the same diameter, the water pressure and flow rate of each water intake connecting pipe 4.5 are the same. This ensures that the water pressure and flow rate of each water intake connecting pipe 4.5, the water intake flow rate of the corresponding water intake funnel, and the water intake flow rate of the lateral flow shallow pool sedimentation module outlet and its corresponding small area are all the same. This allows water to be extracted evenly and in equal amounts from each small area at the outlet of the lateral flow shallow pool sedimentation module, ensuring that each horizontal pipe at different water depths operates according to the designed technical parameters, thereby achieving high-quality sedimentation results consistent with the design. This eliminates the drawbacks of existing technologies using overflow-type water intake methods, which cannot extract water evenly and result in poor sedimentation effects.

[0040] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] See Figure 2 , 8 As shown, a distributed uniform water intake system in a lateral flow shallow pool sedimentation device of the present invention includes a water intake device;

[0042] In the pool behind the lateral flow shallow sedimentation module 2, a water intake device 4 is installed; the water intake device 4 includes: a water intake bell mouth 4.1, a partition wall 4.2, a water collection pipe or water collection trough 4.3, a water collection inlet pipe 4.4, and a water intake connecting pipe 4.5; behind the outlet of the lateral flow shallow sedimentation module 2, and at certain intervals, a clean water intake level is provided, which is composed of several large bell mouths of water intake bell mouths 4.1 and is parallel to the outlet section of the lateral flow shallow sedimentation module; a partition wall 4.2 is vertically installed behind the clean water intake level to isolate the pool water; behind the partition wall is a waterless area; a water collection pipe or water collection trough 4.3 is installed above the waterless area and not higher than the water level line of the upper part of the lateral flow shallow sedimentation module 2;

[0043] The purified water sample is evenly divided into several small grid areas, see [reference]. Figure 6 As shown, in each corresponding small area, a water intake funnel 4.1 is installed to introduce purified water discharged from the corresponding small area through the outlet section of the lateral flow shallow pool sedimentation module; the rear end of each water intake funnel is installed at the starting end of its respective water intake connecting pipe 4.5; multiple water intake connecting pipes first pass horizontally through the partition wall 4.2 and then extend upwards, see [reference]. Figure 7 , 8As shown, each end of the water inlet pipe 4.4 is connected one-to-one to one end of several water inlet pipes 4.4 installed above the central axis of the water collection pipe or water collection tank 4.3 (i.e., the end of a water intake connecting pipe 4.5 connected to a water intake funnel 4.1 is connected to one end of the water inlet pipe 4.4); one or both ends of the water inlet pipe 4.4 are connected one-to-one to the ends of different water intake connecting pipes 4.5; several water inlet pipes 4.4 above the central axis of the water collection pipe or water collection tank 4.3 are all set on the same horizontal plane at the same height, arranged side by side in parallel, and all have the same pipe diameter, so that the water pressure and water flow of each water intake connecting pipe 4.5 are the same;

[0044] The water inlet pipe 4.4 has its lower half-pipe removed from the water collection pipe or water collection tank 4.3, forming a half-pipe 4.41 with an opening at the lower end 4.42. Water from the water inlet pipes at both ends can fall into the water collection pipe or water collection tank 4.3 through the opening 4.42 at the removed half-pipe.

[0045] The distributed uniform water intake system in the lateral flow shallow pool sedimentation device is described above, wherein each of the small areas is rectangular in shape, with a lateral dimension b not greater than 600 mm and a longitudinal dimension h not greater than 400 mm.

[0046] See Figure 3-5 As shown, the distributed uniform water intake system in the lateral flow shallow pool sedimentation device includes a water intake flare 4.1, which is composed of a rectangular flare A, a square-to-round transition section C, and a round pipe connector D connected in sequence. The rectangular flare A has a frustum-shaped structure, with a large flare at the front and a small flare at the rear. The large flare has a lateral dimension of no more than 580 mm and a longitudinal dimension of no more than 380 mm. Multiple uniform water intake partition plates B are installed inside the rectangular flare A, dividing the interior of the rectangular flare A into nine independent water intake channels, forming a nine-square grid of water intakes at both ends of the large and small flare openings. One end of the square-to-round transition section C is a square end, and the other end is a round end. The small flare is connected to the square end, and the round end is connected to the round pipe connector D.

[0047] The distributed uniform water intake system in the lateral flow shallow pool sedimentation device is described above, wherein the wall of the connecting pipe is sealed with the partition wall, and a pipe joint for connecting to the water intake funnel 4.1 is provided on the inner side of the partition wall.

[0048] The distributed uniform water intake system in the lateral flow shallow pool sedimentation device, wherein, see... Figure 8The water collection pipe or water collection tank 4.3 has multiple horizontal and coaxial mounting holes at approximately 45° above its horizontal axis for inserting and fixing the water collection inlet pipe 4.4. The hole diameter is DN80. The number of holes is as follows: when the sedimentation module height H = 1500mm, the water collection pipe or water collection tank 4.3 has 2 sets of mounting holes every 600mm; when the sedimentation module height H = 3000mm, the water collection pipe or water collection tank 4.3 has 4 sets of mounting holes every 600mm. Each set of mounting holes includes two mounting holes facing each other, with a water collection inlet pipe 4.4 installed between them. A pipe joint connecting the water collection inlet pipe 4.4 and the connecting pipe is provided outside the mounting holes.

[0049] This invention discloses a distributed uniform water intake method in a lateral flow shallow pool sedimentation device. The purified water output from the lateral flow shallow pool sedimentation module 2 is drawn from a purified water intake surface located in the pool behind it. This purified water intake surface is uniformly divided into several small grid areas, and correspondingly equipped with several water intake bell-shaped openings 4.1 connected to connecting pipes to draw water from the pool. Each connecting pipe passes through a partition wall in the pool and enters a waterless area, delivering purified water to several corresponding water collection inlet pipes. Each water collection inlet pipe is located on a horizontal surface at the same height. The pipes are arranged in parallel with the same diameter to ensure that the water pressure and flow rate of each water intake connecting pipe 4.5, the water intake flow rate of the corresponding water intake funnel, and the water intake flow rate of the lateral flow shallow pool sedimentation module outlet and its corresponding small area are all the same. Several water collection inlet pipes are set in the water collection pipe or water collection tank 4.3 and can be connected to the connecting pipes at both ends for water intake. The half-pipe below the central axis of the water collection inlet pipe is removed to form a half-pipe with an open bottom. The water coming in from the water intake connecting pipes connected at both ends falls into the water collection pipe or water collection tank 4.3 through the opening at the removed half-pipe to complete the water intake.

[0050] The method for distributed uniform water intake in a lateral flow shallow pool sedimentation device, wherein the water inlet pipe is installed on a coaxial mounting hole on the left and right pipe walls at a position approximately 45° above the horizontal axis of the water collection pipe or water collection tank 4.3.

[0051] The working principle of this invention is as follows:

[0052] In the side-flow shallow pool sedimentation process, the final step is to collect and extract the purified water after treatment by the side-flow shallow pool sedimentation module 2. This invention employs a distributed uniform water intake system for this final step. First, the water effluent from the side-flow shallow pool sedimentation module 2 enters each water intake funnel 4.1. The entire process is as follows:

[0053] The water intake funnel 4.1 in each area, due to its funnel structure and the gradually narrowing nine-square grid structure set inside the funnel, can draw water evenly from each position in the area. That is, the water in each position in the area corresponding to the water intake funnel at the outlet of the lateral flow shallow pool sedimentation module is evenly drawn out and flows into the water collection pipe or water collection tank 4.3 through the water intake connecting pipe.

[0054] Because all the water inlet pipes 4.4 are on the same horizontal plane, the water pressure flowing into the water inlet pipes 4.4 is the same; and because the pipe diameter is the same, the water pressure and flow rate flowing into each water inlet pipe 4.4 are the same; based on this principle, the water intake of each water intake funnel at the outlet section of the lateral flow shallow pool sedimentation module is the same, that is, the flow rate at all locations at the outlet section of the lateral flow shallow pool sedimentation module is the same.
