Description

Technical Field

[0001] The present application relates to the field of seawater desalination treatment, and in particular to a clean water tank and a seawater desalination treatment system. Background Art

[0002] The desalination process utilizes seawater desalination. It typically begins by pumping seawater into a lake for storage. Then, a pumping station extracts seawater from the lake and pre-filters and ultrafilters it for sedimentation and scum removal. The water is then sent to an ultrafiltration tank for storage. The seawater in the ultrafiltration tank then undergoes multi-stage reverse osmosis treatment to achieve desalination. The desalinated water is then sent to a clean water tank for storage. Since all desalinated water shares a common characteristic: a low mineral salt content and a slightly acidic pH, the pH of the desalinated water is adjusted according to usage requirements before it is finally exported, completing the desalination process.

[0003] Among them, the clear water tank serves as the last set of equipment for seawater desalination treatment. Its interior generally adopts multiple baffles with gradually decreasing heights, thereby dividing the clear water tank into multiple water storage parts with gradually decreasing heights, so as to realize the gradual slowing down of the desalinated water in the clear water tank. However, the baffle can only realize the slowing down of the water flow in the clear water tank. Since the end of the clear water tank generally needs to add chemicals or ores or input other water sources for pH adjustment, the water storage area at the end of the clear water tank is generally used as the acid-base blending area. However, after working for a period of time, the acid-base blending area is prone to produce impurities due to additives, so it needs to be cleaned. Since the baffle cannot completely isolate the water flow in the clear water tank, it is necessary to stop or reduce the water inlet speed of the clear water tank to prevent the water flow from other water storage parts from flowing into the acid-base blending area in order to realize the cleaning of the clear water tank. Such operation is more troublesome and affects the desalination efficiency of the seawater desalination system. Summary of the Invention

[0004] In order to facilitate the connection and isolation between the water storage area and the acid-base blending area in the clear water tank, and to ensure that the water storage area of ​​the clear water tank can still be stably filled with water when the acid-base blending area of ​​the clear water tank is clean, the present application provides a clear water tank and seawater desalination system.

[0005] In the first aspect, the present application provides a clear water pool, which adopts the following technical solution:

[0006] A clear water pool, comprising:

[0007] Pool body;

[0008] The upper baffle is vertically fixed on the upper side of the tank body;

[0009] A movable lower baffle is parallel to the upper baffle and vertically arranged on the lower side of the pool body, dividing the pool body into a water storage area and a blending area. The lower baffle moves away from the upper baffle to form a gap between the lower baffle and the upper baffle, and moves toward the upper baffle to close the gap between the lower baffle and the upper baffle.

[0010] The driving component is arranged on the pool body and is used to drive the lower baffle to move.

[0011] By adopting the above technical solution, under normal conditions, the driving component drives the lower baffle to move away from the upper baffle, so that a gap is formed between the upper and lower baffles, so that the water in the water storage area of ​​the pool body can flow through the gap to the blending area of ​​the pool body, and the upper and lower baffles can cooperate to realize the deflection of desalinated water in the pool body, thereby avoiding excessive flow of desalinated water. When it is necessary to adjust the water flow rate from the water storage area to the blending area, the driving component can be used to adjust the gap between the lower and upper baffles, thereby adjusting the water flow rate from the water storage area to the blending area; when it is necessary to clean the blending area in the pool body, the driving component drives the lower baffle to move toward the upper baffle, so that the upper and lower baffles cooperate to close the gap. At this time, the blending area is completely isolated from the water storage area, so that the blending area can be cleaned, and the water storage space of the water storage area is increased due to the sealing of the lower and upper baffles, so that desalinated water can still enter the water storage area for storage without stopping or reducing the desalinated water entering the pool body.

[0012] Optionally, the lower baffle is arranged on a side of the upper baffle close to the blending zone, and the lower baffle includes:

[0013] Soft curtain, set vertically and with the lower end fixed to the bottom of the pool;

[0014] A plurality of horizontally arranged support plates are fixed in a vertical arrangement on one side of the soft curtain close to the upper baffle, and when the soft curtain is in a vertical state, adjacent support plates abut against each other;

[0015] The first holding member passes through each support plate from bottom to top along the multiple support plates and is fixed to the uppermost support plate, and its lower end is connected to the driving component. The first holding member holds the support plate to close the lower baffle and the upper baffle.

[0016] By adopting the above technical solution, a soft curtain and multiple support plates are used to form a bendable and deformable shielding body, and then the first pulling member cooperates with the support plate. When it is necessary to open the gap between the upper baffle and the lower baffle, the first pulling member is driven to relax by the driving member, and the lower baffle can be bent away from the upper baffle under the impact of the water flow, and due to the support of the first pulling member, the lower baffle will not collapse. At this time, the driving member is used to pull the first pulling member closer to adjust the bending angle of the lower baffle, thereby adjusting the size of the gap between the upper baffle and the lower baffle and the height of the upper baffle at this time, and then adjusting the water flow from the water storage area to the blending area. When it is necessary to clean the blending area, the first pulling member is used to pull the support plate to drive the soft curtain to swing towards the upper baffle at the same time, so as to achieve the closure between the lower baffle and the upper baffle, thereby preventing water from the water storage area from flowing into the blending area, and facilitating the cleaning of the blending area.

[0017] Optionally, the lower baffle further includes:

[0018] The second holding member has an upper end fixed to the upper end of the soft curtain and a lower end connected to the driving component.

[0019] By adopting the above technical solution, the cooperation between the first holding member and the second holding member can ensure that the upper baffle maintains its bent state when it is in a bent state, thereby improving the stability of the bent state of the soft curtain.

[0020] Optionally, the outer sides of the soft curtain and the support plate are wrapped with an elastic sleeve.

[0021] By adopting the above technical solution, the elastic sleeve is wrapped around the soft curtain and the support plate, which can effectively protect the soft curtain and the support plate on the one hand. On the other hand, the elastic sleeve relies on its own deformability to swing with the soft curtain and the support plate, and when the elastic sleeve contacts the pool wall and the upper baffle, it relies on its own elasticity to also improve the sealing.

[0022] Optionally, the lower side of the lower baffle is rotatably connected to the bottom of the pool body.

[0023] By adopting the above technical solution, the driving component drives the lower baffle to swing away from the upper baffle, the gap size between the lower baffle and the upper baffle can be adjusted, and the upper side height of the upper baffle can be adjusted at the same time, thereby adjusting the water flow rate from the water storage area to the blending area to meet normal working needs. When it is necessary to close the gap between the upper baffle and the lower baffle, the driving component drives the lower baffle to swing toward the upper baffle, so that the upper baffle and the lower baffle can separate the water storage area and the blending area. On the one hand, it is convenient for water to enter the water storage area normally, and on the other hand, it prevents water from entering the blending area, which facilitates the cleaning of the blending area.

[0024] Optionally, a sealing sleeve is fixed to the lower side of the lower baffle, and the sealing sleeve seals the lower baffle and the rotating part of the pool body.

[0025] By adopting the above technical solution, the provided sealing sleeve can, on the one hand, seal the rotating part of the lower baffle and the pool body, thereby preventing desalinated water from invading the lower baffle and the rotating part of the pool body; on the other hand, the sealing sleeve can deform along with the swing of the lower baffle through its own elastic deformation ability, thereby always protecting the rotating part of the lower baffle and the pool body.

[0026] Optionally, a plurality of partition plates perpendicular to the upper baffle are fixed in the blending zone to divide the blending zone into a plurality of blending zones;

[0027] The lower baffles include a plurality of lower baffles, which are respectively arranged on a side of each blending partition close to the upper baffle.

[0028] By adopting the above technical solution, the multiple partition plates can divide the blending area into multiple blending partitions, and a lower baffle is provided on the side of each blending partition close to the upper baffle. Different pH values ​​of desalinated water can be adjusted through each blending partition to meet different needs.

[0029] Optionally, the pool walls of the pool body are all wrapped with glass plates.

[0030] By adopting the above technical solution, since the mineral salt content of desalinated water is low and the pH is weakly acidic, in order to avoid mutual corrosion between the clean water pool wall and the desalinated water, the pool wall is made of glass plate, which can effectively avoid mutual corrosion between the desalinated water and the pool wall.

[0031] Optionally, a plurality of upper baffles are vertically fixed on the upper side of the water storage area along the direction of water flow;

[0032] A lower baffle is provided on the lower side of the water storage area corresponding to one side of each upper baffle close to the blending area.

[0033] By adopting the above technical solution, by setting up multiple upper baffles in the water storage area in conjunction with the lower baffle, the water flow in the water storage area can be continuously deflected, thereby slowing down the potential energy of the water flow entering the clear water pool and making the water flow in the water storage area flow smoothly.

[0034] In a second aspect, the present application provides a seawater desalination system, which adopts the following technical solution:

[0035] A seawater desalination system comprises the above-mentioned clear water tank.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] Under normal conditions, the lower baffle tends to move away from the upper baffle, so that an adjustable gap is formed between the upper and lower baffles. Thus, the flow rate of water from the water storage area to the blending area of ​​the pool body can be adjusted according to the needs of use. The gap between the lower baffle and the upper baffle can be adjusted by the driving component to adjust the flow rate of water from the water storage area to the blending area, so that the water flow from the water storage area of ​​the clear water tank to the blending area meets the normal working requirements.

[0038] When the blending area in the tank needs to be cleaned, the lower baffle moves toward the upper baffle, so that the upper baffle cooperates with the lower baffle to close the gap. At this time, the blending area is completely isolated from the water storage area, and the blending area can be cleaned, so that desalinated water can still enter the water storage area for storage without stopping or reducing the flow of desalinated water into the tank.

[0039] A flexible curtain and multiple support plates are combined to form a deformable shielding body. The shielding body is then pulled by a first holding member to adjust the bending angle of the lower baffle, thereby adjusting the size of the gap between the upper baffle and the lower baffle and the height of the upper baffle at this time, thereby adjusting the water flow from the water storage area to the blending area.

[0040] When the blending area needs to be cleaned, the shielding body is pulled by the pulling member, driving the shielding body to swing toward the upper baffle, thereby achieving a seal between the lower baffle and the upper baffle, preventing water from the water storage area from flowing into the blending area, and facilitating cleaning of the blending area.

[0050] The following is combined with Figure 1-8 This application is described in further detail.

[0051] The present application discloses a clear water tank, which is primarily used in a seawater desalination system. The tank is primarily designed to achieve arbitrary connectivity and isolation between the water storage area and the acid-base adjustment area within the clear water tank, so that while the acid-base adjustment area of ​​the clear water tank is being cleaned, the water storage area of ​​the clear water tank can still receive water stably. The following is a further detailed description:

[0052] Example 1:

[0053] Reference Figure 1 A clear water pool includes a pool body 1. The pool body 1 is a long rectangular structure as a whole. The upper side of the pool body 1 is open. An upper baffle 2 is vertically arranged in the pool body 1. The upper baffle 2 is vertically fixed to the upper side of the pool body 1, and the length direction of the upper baffle 2 is perpendicular to the length direction of the pool body 1.

[0054] Reference Figure 1 and Figure 2 A lower baffle 3 is vertically provided on one side of the bottom of the pool body 1 corresponding to the upper baffle 2. The lower baffle 3 is movably connected to the pool body 1. The upper baffle 2 and the lower baffle 3 have the same length direction. With the movement of the upper baffle 2, the lower side of the upper baffle 2 can be made lower than the upper side of the lower baffle 3, so that a gap can be formed between the upper baffle 2 and the lower baffle 3, and with the movement of the upper baffle 2, the upper baffle 2 can also be abutted against the lower baffle 3 to close the gap between the upper baffle 2 and the lower baffle 3.

[0055] In this way, the upper baffle 2 and the lower baffle 3 divide the pool body 1 into a water storage area 11 located at the front end of the pool body 1 and a blending area 12 located at the rear end of the pool body 1, and the blending area 12 is provided with a drain pipe 13, and the drain pipe 13 is provided with a drain valve 131 for discharging water.

[0056] Reference Figure 1 and Figure 2In summary, when it is necessary to blend the desalinated water, the lower baffle plate 3 is adjusted to move away from the upper baffle plate 2 to open the gap. After the desalinated water enters the pool body 1, the desalinated water will first enter the water storage area 11 of the pool body 1, and then flow into the blending area 12 through the gap between the upper baffle plate 2 and the lower baffle plate 3. Chemicals, other water sources, rocks and minerals can be added to the blending area 12 to achieve the blending of the desalinated water; and when it is necessary to clean the blending area 12 of the pool body 1, the lower baffle plate 3 is moved toward the upper baffle plate 2, so that the lower baffle plate 3 can be abutted against the upper baffle plate 2, and then the gap between the upper baffle plate 2 and the lower baffle plate 3 is closed, so as to achieve the isolation between the water storage area 11 and the blending area 12, and then the blending area 12 can be conveniently cleaned without disconnecting the water inlet of the water storage area 11 of the pool body 1.

[0057] Reference Figure 2 Specifically, the lower baffle 3 is arranged on the side of the upper baffle 2 close to the blending area 12, and a rotating shaft 31 is fixed to the lower end of the lower baffle 3 along the length direction of the lower baffle 3. The rotating shaft 31 is rotatably connected to the pool body 1, and a driving component is provided at one end of the rotating shaft 31 on the outside of the pool body 1, which is used to drive the rotating shaft 31 to rotate and lock the position. Specifically, the driving component can be a stepping motor, a servo motor, or other components that can drive the rotating shaft 31 to rotate and lock the position.

[0058] Reference Figure 2 In this way, when it is necessary to open the gap between the lower baffle 3 and the upper baffle 2, the driving component drives the rotating shaft 31 to rotate, which can drive the lower baffle 3 to swing in the direction away from the upper baffle 2, so that the desalinated water in the water storage area 11 can flow into the blending area 12, and because the swing amplitude of the lower baffle 3 driven by the driving component can be adjusted, the gap size between the upper baffle 2 and the lower baffle 3, as well as the maximum liquid level height of the water storage area 11 and the blending area 12, can be adjusted, the water flow rate of the desalinated water from the water storage area 11 to the blending area 12, and the water storage amount of the water storage area 11 and the blending area 12 can be adjusted to meet different needs.

[0059] Reference Figure 2 When the gap between the lower baffle 3 and the upper baffle 2 needs to be closed, the driving component drives the rotating shaft 31 to rotate, which can drive the lower baffle 3 to swing toward the upper baffle 2 until the lower baffle 3 abuts against the upper baffle 2, and the gap can be closed. That is, the upper baffle 2 and the lower baffle 3 cooperate to isolate the water storage area 11 from the blending area 12. In this way, the desalinated water in the water storage area 11 will not be able to flow into the blending area 12. Moreover, since the upper baffle 2 and the lower baffle 3 cooperate to form a cavity with closed side walls in the water storage area 11, the water storage capacity of the water storage area 11 can also be increased, so as to store a large amount of water in the water storage area 11 for a short time.

[0060] Refer to 1 and Figure 2Furthermore, in order to protect the hinged position between the lower baffle 3 and the pool body 1 and isolate the desalinated water from entering, sealing soft sleeves 32 are fixed to the lower ends of both sides of the swing plate and the bottom of the pool body 1. The two ends of the sealing soft sleeve 32 are also fixed to the side wall of the pool body 1. The sealing soft sleeve 32 can be made of corrosion-resistant rubber material.

[0061] In this way, the provided sealing sleeve 32 can, on the one hand, seal the rotating part of the lower baffle 3 and the pool body 1, thereby preventing desalinated water from invading the lower baffle 3 and the rotating part of the pool body 1; on the other hand, the sealing sleeve 32 can deform along with the swing of the lower baffle 3 through its own elastic deformation ability, thereby always protecting the rotating part of the lower baffle 3 and the pool body 1.

[0062] Furthermore, in order to improve the sealing between the two ends of the lower baffle plate 3 and the side wall of the pool body 1 and the sealing when the lower baffle plate 3 abuts the upper baffle plate 2, sealing gaskets are fixed to the two ends of the lower baffle plate 3 and the upper side of the lower baffle plate 3 close to the upper baffle plate 2, so that the sealing between the lower baffle plate 3 and the side wall of the pool body 1 and the sealing when the upper baffle plate 2 abuts the lower baffle plate 3 can be improved, thereby preventing water from flowing out from between the side wall of the pool body 1 and the lower baffle plate 3 or preventing water from flowing out from between the upper baffle plate 2 and the lower baffle plate 3 when they abut.

[0063] Furthermore, in order to facilitate the cleaning of the side walls of the pool body 1 , the side walls and the bottom of the pool body 1 can be wrapped with glass plates, thereby conveniently cleaning the side walls of the pool body 1 .

[0064] Example 2:

[0065] Reference Figure 2 , a clear water tank, which differs from Example 1 in the structure of the lower baffle 3 and the connection method between the lower baffle 3 and the tank body 1, which is further described in detail below:

[0066] Refer to 4 and Figure 5 The lower baffle 3 mainly includes a soft curtain 33 and a plurality of support plates 34. The soft curtain 33 is arranged vertically and the lower end of the soft curtain 33 is fixed to the bottom surface of the pool body 1. The length direction of the soft curtain 33 is the same as the width direction of the pool body 1. The soft curtain 33 can be made of a hard material with a certain deformation ability, such as a steel plate, an alloy plate, etc. The length direction of the multiple support plates 34 is the same as the length direction of the soft curtain 33, and the multiple support plates 34 are arranged along the height direction of the soft curtain 33 and fixed to the side of the soft curtain 33 close to the upper baffle 2.

[0067] Reference Figure 4 and Figure 6In this way, when the soft curtain 33 tends to swing away from the upper baffle 2, the multiple support plates 34 will swing with the soft curtain 33, and gaps will be generated between adjacent support plates 34 to ensure smooth bending of the soft curtain 33. When the soft curtain 33 tends to swing towards the upper baffle 2 to a vertical state, the adjacent support plates 34 on the soft curtain 33 will abut against each other, thereby limiting the further bending of the soft curtain 33. At this time, the soft curtain 33 will also be restricted by the multiple support plates 34 to achieve vertical fixation. In addition, when the soft curtain 33 rotates to a vertical state, the lower baffle 3 will also be able to abut against the upper baffle 2, achieving abutment between the upper baffle 2 and the lower baffle 3.

[0068] Reference Figure 5 The outer sides of the soft curtain 33 and the multiple support plates 34 are integrally covered with an elastic sleeve 35. The elastic sleeve 35 can be made of corrosion-resistant rubber to achieve the overall wrapping of the soft curtain 33 and the support plates 34. Both ends of the elastic sleeve 35 can abut against the side walls of the pool body 1, and the lower end of the elastic sleeve 35 is fixed to the bottom surface of the pool body 1. In this way, on the one hand, the elastic sleeve 35 can effectively protect the soft curtain 33 and the support plates 34; on the other hand, the elastic sleeve 35 has the ability to automatically bend and deform with the bending of the soft curtain 33, so that the elastic sleeve 35 can swing with the soft curtain 33; on the other hand, the elastic sleeve 35 relies on its own elastic deformation to enhance the sealing between it and the side walls, and when the upper baffle 2 abuts against the lower baffle 3, the lower baffle 3 will also rely on its own elastic deformation ability to improve the sealing between the upper baffle 2 and the lower baffle 3.

[0069] Reference Figure 5 and Figure 6 The cell body 1 is further provided with a first holding member 36, a second holding member 37 and a driving component.

[0070] Reference Figure 5 and Figure 6 The first holding member 36 is a holding rope, which is a high-strength rope, such as a steel rope. The holding rope passes through each support plate 34 from bottom to top along the arrangement direction of the support plates 34 and is fixed to the uppermost support plate 34 of the soft curtain 33. The driving component includes a first winding member 361 fixed to the position below the pool body 1 corresponding to the first holding member 36. The first winding member 361 can be a winch to achieve winding or unwinding of the first holding member 36.

[0071] Reference Figure 5 and Figure 6 The second holding member 37 also includes a holding rope, and the material is the same as that of the first holding member 36. One end of the second holding rope passes through the elastic sleeve 35 and is fixed to the upper end of the soft curtain 33. The driving component also includes a second winding member 371 fixed to the bottom of the pool body 1 corresponding to the lower end of the second holding member 37. The second winding member 371 can also use a winch to realize the winding or unwinding of the second holding member 37.

[0072] Reference Figure 4 and Figure 6 In summary, when the gap between the upper baffle 2 and the lower baffle 3 needs to be opened, the first holding member 36 is unwound by the first winding member 361, and the second holding member 37 is rewound by the second winding member 371, so that the first holding member 36 and the second holding member 37 cooperate with each other, and the lower baffle 3 can be bent away from the upper baffle 2 and maintain its position without collapsing. The bending angle of the lower baffle 3 can be adjusted, thereby adjusting the size of the gap between the upper baffle 2 and the lower baffle 3 and the height of the upper baffle 2 at this time, thereby adjusting the water flow from the water storage area 11 to the blending area 12;

[0073] When the blending area 12 needs to be cleaned, the first holding member 36 is reeled in by the first reeling member 361, and the second holding member 37 is unreeled by the second reeling member 371, so that the soft curtain 33 can be driven to swing toward the upper baffle 2 to a vertical state, thereby realizing the closure between the lower baffle 3 and the upper baffle 2, preventing water from the water storage area 11 from flowing into the blending area 12, and facilitating the cleaning of the blending area 12.

[0074] Furthermore, in order to ensure the stability of the lower baffle 3 when it is bent into different angles, multiple first holding members 36 and multiple second holding members 37 can be provided to improve the stability of the lower baffle 3 during operation.

[0075] Example 3:

[0076] A clear water tank, which differs from Example 1 and Example 2 in that:

[0077] Reference Figure 7 and Figure 8 Multiple partitions 4 are vertically fixed within the blending zone 12. These partitions 4 are arranged along the width of the tank body 1, with the upper end of each partition 4 flush with the upper side of the tank body 1. Each partition 4 divides the blending zone 12 into multiple blending zones 41 along the width of the tank body 1. Each blending zone 41 is connected to a drain pipe 13 and a drain valve 131 at the end facing away from the upper baffle 2, for draining water from the blending zone 41. Each blending zone 41 is provided with a lower baffle 3 on the side closest to the upper baffle 2, which regulates the flow of water from the water storage zone 11 into each blending zone 41.

[0078] In this way, the multiple partition plates 4 can divide the blending area 12 into multiple blending partitions 41, and a lower baffle 3 is provided on the side of each blending partition 41 close to the upper baffle 2. Different pH values ​​of desalinated water can be adjusted through each blending partition 41 to meet different needs.

[0079] Reference Figure 7 and Figure 8Furthermore, a plurality of upper baffles 2 are provided on the upper side of the water storage area 11 along the length direction of the pool body 1, that is, the flow direction of the water flow. The plurality of upper baffles 2 are all provided along the width direction of the pool body 1, and a lower baffle 3 is provided at the bottom of the water storage area 11 at the position corresponding to each upper baffle 2. The lower baffle 3 is also provided along the width direction of the pool body 1. In this way, the plurality of upper baffles 2 and the lower baffle 3 cooperate to divide the water storage area 11 into a plurality of water storage partitions 14.

[0080] In this way, by setting up multiple water storage partitions 14, the water flow in the water storage area 11 can be continuously deflected, thereby slowing down the potential energy of the water flow entering the clear water tank and making the water flow in the water storage area 11 flow smoothly.

[0081] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
