Description

Technical Field

[0002] Seawater desalination technology has become one of the important means to solve the global water shortage and is widely used in islands, ships and coastal water-scarce areas. Seawater desalination technology has undergone multiple generations of innovation, from the early distillation method to the modern reverse osmosis membrane technology, which has greatly improved the efficiency and water quality of desalination and reduced energy consumption.

[0003] The process commonly used in the existing seawater desalination process includes primary filtration, membrane filtration and mineralization. Among them, primary filtration is to remove large particles of impurities in seawater, while membrane filtration is to further remove tiny pollutants. After the above steps, mineralization is used to add minerals that are beneficial to human health. Only after mineralization can the water be transported to the municipal pipeline network for people to use. However, after the water passes through the mineralized filter material, the water flow during the water volume fluctuation or start-stop stage can easily wash up the ore filter material, resulting in high turbidity of the produced water, which affects the stability of the final output water quality.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The embodiment of the present application discloses a mineralized filter tank for producing water with low turbidity.

[0037] Example 1 Reference Figure 1 and Figure 2The mineralized filter tank for producing low turbidity water includes a mineralized pool 1 for containing water in the mineralization process, a filter material layer 11 installed in the mineralized pool 1, a buffer layer 12 arranged in the mineralized pool 1, and a sediment layer 13 arranged in the mineralized pool 1. A water inlet 14 and a water outlet 15 are provided on the mineralized pool 1. The water inlet 14 is provided on the side wall of the mineralized pool 1 and is located at the lower part of the mineralized pool 1. The water outlet 15 is provided on the side wall of the mineralized pool 1 and is located at the upper part of the mineralized pool 1. The buffer layer 12 is located between the water inlet 14 and the filter material layer 11, so that the water to be mineralized entering from the water inlet 14 will reach the filter material layer 11 after being buffered by the buffer layer 12, thereby reducing the impact on the filter material layer 11. The sedimentation assembly 2 is located between the filter material layer 11 and the water outlet 15. The sedimentation assembly 2 is arranged in the sedimentation layer 13. The sedimentation assembly 2 is used to extend the flow path of the mineralized water so that the mineralized water can flow out from the water outlet 15 after being deposited in the sedimentation layer 13, so that the filter material carried in the water can be fully deposited, thereby reducing the turbidity of the water.

[0038] Reference Figure 2 , a buffer plate 121 is arranged in the buffer layer 12, and the buffer plate 121 can be made of ABS plastic material, which has good toughness and corrosion resistance. Multiple buffer plates 121 are arranged at intervals along the height direction of the mineralization pool 1, and two adjacent buffer plates 121 are respectively fixed on the inner walls on both sides of the mineralization pool 1. A serpentine buffer channel is formed between the multiple buffer plates 121, so that after the water flow from the water inlet 14 reaches the mineralization pool 1, it will follow the buffer channel to reach the filter material layer 11, and the water will be buffered in the buffer channel, and the pressure and speed will be evenly distributed. This design makes the water pressure act on the buffer plate 121 when the water flows through the buffer layer 12, so as to buffer the water through the buffer plate 121, so that the water pressure and speed become relatively uniform, reduce the impact on the filter material layer 11, and effectively reduce the turbidity of the produced water.

[0039] The filter material layer 11 mainly includes a mineralized filter material 111 and a support net 112 for supporting the mineralized filter material 111. The mineralized filter material 111 is made of shell filter material, limestone filler and other materials, and the support net 112 is made of 304 stainless steel, which has high strength and hardness, and has good corrosion resistance to support the mineralized filter material 111. A plurality of filter material layers 11 can be arranged at intervals along the height direction of the mineralization pool 1. The present application takes two filter material layers 11 as an example for explanation, and the two filter material layers 11 are respectively referred to as the first filter layer 113 and the second filter layer 114. The first filter layer 113 is located on the lower side of the second filter layer 114, and the diameter of the mineralized filter material 111 in the first filter layer 113 is larger than the diameter of the mineralized filter material 111 in the second filter layer 114. The filter material layer 11 structure designed in this way can not only ensure the effective mineralization treatment, so that the water is graded and mineralized, but also avoid the excessive impact of the water flow on the mineralized filter material 111, effectively reducing the turbidity of the produced water.

[0040] The sedimentation assembly 2 includes a spiral blade 21 installed in the mineralization pool 1. The spiral angle of the spiral blade 21 can be set between 5 and 40 degrees. The present application takes the spiral angle of the spiral blade 21 as an example for explanation, and a spiral channel 22 for water to flow through is formed at the spiral blade 21. After the water flows through the mineralized filter material layer 11, the water will flow along the spiral channel 22 under the action of the spiral blade 21, increasing the flow space of the water flow, so that the mineralized filter material 111 carried in the water flow can be deposited, and the deposited mineralized filter material 111 will fall to the filter material layer 11 along the spiral channel 22, and the deposited water will also reach the water outlet 15 along the spiral channel 22, and finally be discharged from the water outlet 15, thereby reducing the problem of high turbidity of the produced water caused by the water flow carrying the filter material out, thereby reducing the probability of the water flow impacting the mineralized filter material 111, and significantly reducing the turbidity of the produced water.

[0041] Reference Figure 1 and Figure 2 A carbon dioxide tank 16 for supplying carbon dioxide to the inside of the mineralization pool 1 is provided on one side of the mineralization pool 1. When water reaches the mineralization pool 1 from the water inlet 14, the carbon dioxide in the carbon dioxide tank 16 is transported to the mineralization pool 1, so that the carbon dioxide is mixed with water and reaches the filter material layer 11 together to slowly dissolve the mineralized filter material 111, so that the dissolved minerals reach the water, thereby realizing the mineralization of the water.

[0042] A carbon dioxide inlet 17 is provided on the side wall of the mineralization pool 1, and the carbon dioxide inlet 17 is located on the side of the buffer plate 121 facing the water inlet 14. At the same time, a through hole 122 is provided on each buffer plate 121, so that the carbon dioxide and water entering the mineralization pool 1 can reach the filter layer from the buffer channel on one hand, and can also reach the filter layer through the through hole 122, so that the carbon dioxide and water are mixed more evenly. At the same time, the provision of the through hole 122 can also further buffer the water, and reduce the excessive impact force exerted on the buffer plate 121 when the water hits the buffer plate 121, thereby reducing the damage to the buffer plate 121.

[0043] A gas outlet 18 for gas discharge is provided on the mineralization pool 1 . The gas outlet 18 is located on the upper side of the water outlet 15 so as to discharge the gas in the mineralization pool 1 .

[0044] The implementation principle of Example 1 of the present application is as follows: when in use, pure water treated by the seawater desalination device will reach the mineralization pool 1 from the water inlet 14, and at the same time, the carbon dioxide in the carbon dioxide tank 16 will also enter the mineralization pool 1 through the carbon dioxide inlet 17, and the carbon dioxide and water will be fully mixed, and then the water will reach the filter material layer 11, so that the filter material is dissolved, and the dissolved minerals will be carried away by the water flow. If the water flow carries part of the filter material, when the water flow reaches the sedimentation layer 13, the water flow will flow along the spiral channel 22, and the filter material carried during the flow will be deposited to reduce the turbidity of the water.

[0045] Example 2 Reference Figure 2 The difference between this embodiment and embodiment 1 is that a support plate 3 is fixedly connected to the inside of the mineralization pool 1, and the support plate 3 is located on the upper side of the water outlet 15. A storage area for storing mineralized filter material 111 is formed above the support plate 3 inside the mineralization pool 1 to realize the replenishment of the mineralized filter material 111.

[0046] Reference Figure 2 and Figure 3 The storage area includes a first storage area 41 for replenishing the first filter layer 113 and a second storage area 42 for replenishing the second filter layer 114. A partition plate 43 for dividing the first storage area 41 and the second storage area 42 is fixedly connected in the mineralization pool 1. A first replenishing pipe 44 for conveying the mineralized filter material 111 in the first storage area 41 to the first filter layer 113 is provided between the first storage area 41 and the first filter layer 113. A second replenishing pipe 45 for conveying the mineralized filter material 111 in the second storage area 42 to the second filter layer 114 is provided between the second storage area 42 and the second filter layer 114. At the same time, a first discharge port 46 connected to the first material storage area 41 and a second discharge port 47 connected to the second material storage area 42 are provided on the support plate 3. The mineralized filter material 111 in the first material storage area 41 will reach the first feeding pipe 44 through the first discharge port 46, and reach the first filter layer 113 along the first feeding pipe 44, so as to replenish the first filter layer 113; and the mineralized filter material 111 in the second material storage area 42 will also reach the second feeding pipe 45 through the second discharge port 47, and reach the second filter layer 114 along the second feeding pipe 45, so as to replenish the second filter layer 114.

[0047] Reference Figure 2 and Figure 4In order to better control the opening and closing of the discharge port, a first blocking plate 48 for blocking the first discharge port 46 and a second blocking plate 49 for blocking the second discharge port 47 are also provided inside the support plate 3. At the same time, a first receiving groove 31 for the first blocking plate 48 to be inserted and slid and a second receiving groove 32 for the second blocking plate 49 to be inserted and slid are provided inside the support plate 3. At the same time, a driving assembly 5 for driving the first blocking plate 48 to slide in the first receiving groove 31 and driving the second blocking plate 49 to slide in the second receiving groove 32 is provided on the mineralization pool 1. When the driving assembly 5 drives the first blocking plate 48 to slide in the first receiving groove 31, the first discharge port 46 can be opened or closed, and when the driving assembly 5 drives the second blocking plate 49 to slide in the second receiving groove 32, the second discharge port 47 can be opened or closed.

[0048] Reference Figure 4 and Figure 5 The first receiving groove 31 and the second receiving groove 32 are both semicircular, and the first sealing plate 48 and the second sealing plate 49 are both quarter-circular, so that when the second sealing plate 49 is located on one side of the second receiving groove 32, the second sealing plate 49 can block the second discharge port 47, and when the second sealing plate 49 rotates to the other side of the second receiving groove 32, the second sealing plate 49 opens the second discharge port 47; the sealing process of the first sealing plate 48 on the first discharge port 46 is consistent with that of the second sealing plate 49.

[0049] Reference Figure 6 The driving assembly 5 mainly includes a driving motor 51 fixedly connected to the mineralization pool 1 and a commutator 52 installed on the output shaft of the driving motor 51. The output shaft of the driving motor 51 passes through the support plate 3. The commutator 52 is located inside the support plate 3. The direction of the force of the output shaft of the driving motor 51 can be changed through the commutator 52, so that the driving motor 51 can drive the first sealing plate 48 to rotate or drive the second sealing plate 49 to rotate.

[0050] Reference Figure 6 and Figure 7The reversing member 52 includes a driving plate 521 slidably connected to the output shaft of the driving motor 51 and a driving member 522 driving the driving plate 521 to slide on the output shaft of the driving motor 51. The driving plate 521 is located between the first blocking plate 48 and the second blocking plate 49. A first clamping column 5211 is arranged on the side of the driving plate 521 facing the first blocking plate 48. A plurality of first clamping columns 5211 are arranged at intervals around the axis of the output shaft of the driving motor 51. A first clamping groove 481 for inserting the first clamping column 5211 is provided on the side of the first blocking plate 48 facing the driving plate 521; a second clamping column 5212 is arranged on the side of the driving plate 521 facing the second blocking plate 49.

A second clamping groove 491 for inserting the second clamping column 5212 is provided on the side of the second blocking plate 49 facing the driving plate 521. Under normal conditions, the first blocking plate 48 blocks the first discharge port 46, and the second blocking plate 49 blocks the second discharge port 47; when the first filter layer 113 needs to be supplemented, the driving member 522 drives the driving plate 521 to slide toward the first blocking plate 48, so that the first clamping column 5211 is inserted into the first clamping groove 481. At this time, when the driving motor 51 drives the driving plate 521 to rotate, the driving plate 521 will also drive the first blocking plate 48 to rotate, so that the first blocking plate 48 rotates to open the first discharge port 46. At this time, the mineralized filter material 111 in the first material storage area 41 will reach the first supplementary material pipe 44 through the first discharge port 46, and reach the first filter layer 113 from the first supplementary material pipe 44, so as to supplement the first filter layer 113. On the contrary, when the second filter layer 114 needs to be supplemented with material, the driving member 522 drives the driving plate 521 to slide toward the second blocking plate 49 so that the second clamping column 5212 is inserted into the second clamping groove 491 .

[0051] Among them, a slide slot 511 is provided on the output shaft of the driving motor 51, and the driving member 522 includes a slider 5221 fixed on the driving plate 521 and slidingly matched with the slide slot 511, a push spring 5222 fixed between one end of the slide slot 511 and the slider 5221, and an electromagnet 5223 for driving the slider 5221 to slide in the direction of the push spring 5222. The electromagnet 5223 is fixed to one end of the slide slot 511 where the push spring 5222 is installed, and a driving block 5224 that can be adsorbed by the electromagnet 5223 is fixed to the side of the slider 5221 facing the push spring 5222. Under normal conditions, the electromagnet 5223 is in a power-off state, and the driving plate 521 abuts against the second blocking plate 49 under the elastic force of the push spring 5222, and the second clamping column 5212 is also inserted into the second clamping slot 491, so that the driving motor 51 drives the second blocking plate 49 to rotate. When the operating electromagnet 5223 is energized, the electromagnet 5223 will absorb the driving block 5224 , thereby driving the driving plate 521 to slide toward the first blocking plate 48 through the driving block 5224 until the first clamping column 5211 is embedded in the first clamping groove 481 .

[0052] In order to facilitate the first clamping column 5211 to be smoothly inserted into the first clamping groove 481 and the second clamping column 5212 to be smoothly inserted into the second clamping groove 491, a plurality of the first clamping column 5211 and the second clamping column 5212 are arranged at intervals around the axis of the driving motor 51, and a plurality of the first clamping groove 481 and the second clamping groove 491 are also arranged at intervals around the axis of the output shaft of the driving motor 51. The first clamping column 5211 and the second clamping column 5212 are both slidably matched with the driving plate 521. Specifically, installation grooves 523 for the first clamping column 5211 and the second clamping column 5212 to be embedded are provided on the opposite sides of the driving plate 521, and a fixing spring 524 is fixedly connected between the bottom of the corresponding installation groove 523 and the first clamping column 5211 and between the bottom of the corresponding installation groove 523 and the second clamping column 5212. The fixing spring 524 is fixedly connected between the bottom of the installation groove 523 and the first clamping column 5211 or the fixing spring 524 is fixed between the bottom of the installation groove 523 and the second clamping column 5212. Under normal conditions, under the action of the fixing spring 524, the first clamping column 5211 and the second clamping column 5212 both extend out of the installation slot 523. When the driving plate 521 abuts against the first blocking plate 48, the first clamping column 5211 corresponding to the first clamping slot 481 will be embedded in the first clamping slot 481, and the remaining first clamping column 5211 will abut against the side wall of the first receiving slot 31 and be abutted against and retracted into the installation slot 523 by the side wall of the first receiving slot 31. When the driving plate 521 abuts against the first blocking plate 48, the first clamping column 5211 fails to be smoothly embedded in the first clamping slot 481. As the driving motor 51 drives the driving plate 521 to rotate, the driving plate 521 also drives the first clamping column 5211 to move around the axis of the output shaft of the driving motor 51 until the first clamping column 5211 reaches the first clamping slot 481 and is smoothly embedded in the first clamping slot 481 under the push of the fixing spring 524.

[0053] Reference Figure 6 and Figure 8 When the mineralized filter material 111 in the material storage area reaches the filter layer, it will accumulate in the filter layer, so that the filter layer has more mineralized filter material 111 on the side close to the first feed pipe 44, and less mineralized filter material 111 on the side of the filter layer away from the first feed pipe 44. Therefore, a leveling component 6 is provided on each support net 112 for placing the mineralized filter material 111 from the material storage area to the filter layer flat.

[0054] Specifically, the leveling assembly 6 includes a rotating shaft 61 rotatably connected to the support net 112, a leveling plate 62 vertically fixed to the end of the rotating shaft 61 away from the support net 112, a fixing member 63 for fixing the position of the leveling plate 62 in the mineralization pool 1, and a rotating member 64 for driving the rotating shaft 61 to rotate. The fixing member 63 can fix the position of the leveling plate 62 in the mineralization pool 1, and the rotating member 64 can drive the leveling plate 62 to rotate, so that the leveling plate 62 pushes the mineralized filter material 111 close to one side of the first feeding pipe 44 to the other side.

[0055] The rotating member 64 includes a rotating ring 641 fixed to both ends of the screed plate 62, a rotating motor 642 for driving the rotating ring 641 to rotate, and a transmission member 643 installed between the rotating motor 642 and the rotating ring 641 for driving the rotating ring 641 to rotate through the rotating motor 642. Among them, the rotating ring 641 is an outer gear ring, and the transmission member 643 includes a gear 6431 rotatably connected to the side wall of the mineralization pool 1 and meshing with the rotating ring 641, and a bevel gear set 6432 installed between the gear 6431 and the output shaft of the rotating motor 642. When the rotating motor 642 is started, the rotating motor 642 will drive the gear 6431 to rotate through the bevel gear set 6432, and then drive the rotating ring 641 to rotate, and the rotating ring 641 will drive the screed plate 62 to rotate around the axis of the rotating shaft 61, so as to smooth the mineralized filter material 111. Ensure the flatness of the upper surface of the filter material layer 11.

[0056] It can be understood that the first feeding pipe 44 is located on the upper side of the screed plate 62, so that the material fed by the first feeding pipe 44 can be smoothly smoothed by the screed plate 62, and a pressure sensor is installed on the upper surface of the screed plate 62 to detect the amount of feeding through the pressure sensor. When the screed plate 62 rotates one circle, when the pressure sensor always detects that there is mineralized material on the screed plate 62, it proves that the height of the mineralized material in the filter layer 11 is now on the upper side of the screed plate 62. At this time, the first discharge port 46 is controlled to be closed to complete the feeding.

[0057] Reference Figure 6 and Figure 8At the same time, a detection assembly 7 for detecting whether the material is lower than the set value is arranged at the two opposite inner walls of the mineralization pool 1. The detection assembly 7 includes an infrared transmitter 71 fixedly connected to the inner wall of the mineralization pool 1 and an infrared receiver 72 fixedly connected to the inner wall of the mineralization pool 1. The infrared transmitter 71 and the infrared receiver 72 are respectively located on the opposite sides of the mineralization pool 1 and are staggered with the axis of the mineralization pool 1. The rotating shaft 61 located in the middle of the mineralization pool 1 will not affect the signal emitted by the infrared transmitter 71 to the infrared receiver 72. Under normal conditions, the signal emitted by the infrared transmitter 71 is blocked by the mineralized filter material 111. When the mineralized filter material 111 is less than the set value, the height of the mineralized filter material 111 is lower than the infrared transmitter 71. At this time, the signal emitted by the infrared transmitter 71 is received by the infrared receiver 72. When the infrared receiver 72 receives the signal emitted by the infrared transmitter 71, it proves that the height of the mineralized filter material 111 is lower than the set value. At this time, the first blocking plate 48 is controlled to rotate in the first receiving groove 31 so that the first discharge port 46 can be opened.

[0058] The fixing member 63 includes a fixing ring 631 placed in the mineralization pool 1 and a fixing bolt 632 for fixing the fixing ring 631 in the mineralization pool 1, and the fixing bolt 632 passes through the side wall of the mineralization pool 1. When in use, the fixing ring 631 is directly placed in the mineralization pool 1 and the fixing ring 631 is abutted against the rotating ring 641, and then the fixing bolt 632 passes through the outer wall of the mineralization pool 1 and abuts against the fixing ring 631, so that the fixing ring 631 can be fixed in the position of the mineralization pool 1, so that the screed plate 62 and the rotating shaft 61 are clamped between the supporting net 112 and the fixing ring 631.

[0059] In order to ensure that the rotating ring 641 can rotate smoothly and the water in the mineralization pool 1 does not reach the transmission member 643 from between the rotating ring 641 and the fixed ring 631, a rotating seal is installed between the fixed ring 631 and the rotating ring 641. The rotating seal can be a V-shaped sealing ring, and the V-shaped opening of the V-shaped sealing ring faces the interior of the mineralization pool 1.

[0060] At the same time, in order to prevent the water in the mineralization pool 1 from reaching the transmission member 643 from the lower side of the rotating ring 641 and causing corrosion to the transmission member 643, a clamping ring is fixedly connected to the lower side of the rotating ring 641, and a rotating seal is also fixedly connected between the outer wall of the clamping ring and the inner wall of the mineralization pool 1. The rotating seal also uses a V-shaped sealing ring, and the V-shaped opening of the V-shaped sealing ring faces the side away from the rotating ring 641.

[0061] The two sides of the transmission member 643 can be sealed by two rotating seals, so that the water in the mineralization pool 1 will not reach the transmission member 643, thereby reducing the probability of the water in the mineralization pool 1 damaging the transmission member 643.

[0062] It is understandable that a control unit is also provided, and the control unit may be any system capable of realizing signal control, such as a single chip microcomputer, a PLC controller, etc. The control unit is connected to the above-mentioned electrical components to realize automated operation.

[0063] The implementation principle of Example 2 of the present application is as follows: when the mineralized filter material 111 in the filter layer decreases with the increase of time, the signal emitted by the infrared transmitter 71 in the filter layer can be received by the infrared receiver 72. At this time, the control unit controls the electromagnetic valve to be powered on or off, and controls the drive motor 51 to start rotating the set angle, and the drive motor 51 opens the corresponding first discharge port 46 or the second discharge port 47 to achieve the feeding of the corresponding filter layer. While feeding, the rotating motor 642 also starts to drive the screed plate 62 to rotate, thereby flattening the filter material. When the pressure sensor detects that the mineralized filter material 111 can be detected on the screed plate 62 within the set time, it means that the feeding reaches the set value. At this time, the drive motor 51 is controlled to rotate in the opposite direction to the set angle, so as to close the first discharge port 46 or the second discharge port 47. At the same time, the rotating motor 642 is also controlled to stop, so that automatic feeding can be achieved.

[0064] It can be understood that, in order to control the rotation angle of the output shaft of the driving motor, an encoder for detecting the rotation amount of the output shaft of the driving motor 51 is installed on the output shaft of the driving motor 51 .

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
