Description

Technical Field

[0001] This invention relates to the field of seawater desalination technology, specifically to an intelligent recycling device for seawater desalination. Background Technology

[0002] Seawater desalination, or the production of fresh water by desalinating seawater, is a technology that increases the amount of fresh water available for water resource utilization. It is unaffected by time, space, or climate, and can ensure a stable water supply for coastal residents' drinking water and industrial boiler feedwater. The process of obtaining fresh water from seawater is called seawater desalination. Currently used seawater desalination methods include seawater freezing, electrodialysis, distillation, reverse osmosis, and ammonium carbonate ion exchange. More than 100 research institutions in more than ten countries around the world are conducting research on seawater desalination, and hundreds of seawater desalination facilities with different structures and capacities are in operation. A modern large-scale seawater desalination plant can produce thousands, tens of thousands, or even nearly a million tons of fresh water per day. The cost of water is constantly decreasing, and in some countries it has dropped to a level similar to that of tap water.

[0003] Currently, reverse osmosis membrane technology is the mainstream method in the market. The operating pressure of reverse osmosis seawater desalination projects in my country is typically between 5.0 and 6.0 MPa, while the pressure of the concentrated seawater discharged from the membrane module remains as high as 4.8 to 5.8 MPa. If we calculate based on a typical water recovery rate of 40%, approximately 60% of the feed pressure energy in the concentrated seawater has significant recovery value and importance. Therefore, an intelligent recovery device for seawater desalination is proposed. Summary of the Invention

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figure 1-8As shown, the present invention provides a technical solution: an intelligent recovery device for seawater desalination. The intelligent recovery device includes a housing 100. A high-pressure seawater pipe 200 is fixedly installed on the lower left side of the outer wall of the housing 100. The high-pressure seawater pipe 200 is used to introduce high-pressure seawater into the device. The high-pressure seawater pipe 200 penetrates the left side of the inner wall of the housing 100, and high-pressure seawater branch pipes 210 are fixedly installed on both the upper and lower sides of the right side of the outer wall of the high-pressure seawater pipe 200. Desalination treatment pipes 300 are fixedly installed on the right ends of both high-pressure seawater branch pipes 210. Reverse osmosis membrane modules 310 are fixedly installed in the middle of the inner walls of both desalination treatment pipes 300. By applying an external pressure greater than the osmotic pressure of seawater to the seawater side, pure water in the seawater is reverse-osmoticed into the reverse osmosis membrane. In module 310, freshwater branch pipes 320 are fixedly installed on the right side of the outer wall of each of the two reverse osmosis membrane modules 310. Freshwater output pipes 330 are fixedly installed on the right side of the outer wall of each of the two freshwater branch pipes 320. The right side of the outer wall of the freshwater output pipe 330 penetrates the right side of the outer wall of the outer shell 100. The purified freshwater is collected and transported out of the device through the freshwater branch pipes 320 and the freshwater output pipe 330. High-pressure brine branch pipes 340 are fixedly installed on the upper right side of the outer wall of each of the two desalination treatment pipes 300. High-pressure brine pipes 350 are fixedly installed on the upper side of the outer wall of each of the two high-pressure brine branch pipes 340. An intermediate frame 400 is fixedly installed on the inner wall of the outer shell 100 above the high-pressure brine pipes 350. The upper part of the outer wall of the high-pressure brine pipes 350 and the lower left side of the outer wall of the intermediate frame 400 are connected. A fixed connection is established, with an intermediate shaft 410 rotatably connected to the upper center of the outer wall of the intermediate frame 400. The lower end of the outer wall of the intermediate shaft 410 passes through the middle of the inner wall of the intermediate frame 400 and is fixedly mounted with a bevel gear 420. A fixing block 430 is fixedly mounted on the upper end of the inner wall of the intermediate frame 400, located to the left of the intermediate shaft 410. A rotating shaft 440 is rotatably connected to the lower end of the outer wall of the fixing block 430. A propeller blade 450 is fixedly mounted on the left end of the outer wall of the rotating shaft 440, and a bevel gear 460 is fixedly mounted on the right end of the outer wall of the rotating shaft 440. The bevel gear 460 meshes with the bevel gear 420. High-pressure seawater can drive the propeller blade 450 to rotate, thereby driving the rotating shaft 440 and the bevel gear 460 to rotate, which in turn drives the bevel gear 420 to rotate, thus causing the intermediate shaft... 410 rotates. A low-pressure brine output pipe 470 is fixedly installed on the right end of the outer wall of the middle frame 400. The low-pressure brine output pipe 470 is used to discharge low-pressure seawater outside the device. An energy recovery frame 500 is fixedly installed on the upper end of the inner wall of the outer shell 100. A fixed base 600 is fixedly installed on the upper end of the inner wall of the energy recovery frame 500. Cylinder 1 610, Cylinder 2 620, Cylinder 3 630 and Cylinder 4 640 are fixedly installed on the four sides of the upper end of the outer wall of the fixed base 600. Pistons 650 are slidably connected to the inner walls of cylinders 1 610, 2 620, 3 630 and 4 640. A rotating wheel 660 is rotatably connected to one end of each piston 650 near the center of the fixed base 600. A connecting rod 670 is rotatably connected between each two adjacent rotating wheels 660.A cam 680 is fixedly connected to the upper end of the outer wall of the intermediate shaft 410, penetrating the lower end of the inner wall of the energy recovery frame 500 and the upper end of the outer wall of the fixed base 600. The cam 680 is slidably connected to four rotating wheels 660. When the intermediate shaft 410 rotates, it drives the cam 680 to rotate. When the cam 680 rotates, it slides against the four rotating wheels 660. Due to the rotation of the cam 680 and the staggered connection of the four connecting rods 670, the rotating wheels 660 reciprocate along the straight line formed by themselves and the center of the fixed base 600 while rotating, thereby driving the four pistons 650 to reciprocate linearly. Holes 700 are opened on the opposite sides of cylinder one 610 and cylinder two 620, and on the opposite sides of cylinder three 630 and cylinder four 640. Holes 700 are also opened at the cylinder one 610 and cylinder two 620. The holes 700 at cylinder 630 and cylinder 640 are connected by connecting pipes 710. One-way valves 720 are fixedly installed on both connecting pipes 710. Low-pressure seawater inlet branch pipes 730 are fixedly installed at the ends of cylinders 620 and 640 away from the center of the fixed chassis 600. One-way valves 740 are fixedly installed on both low-pressure seawater inlet branch pipes 730. High-pressure seawater outlet branch pipes 750 are fixedly installed at the ends of cylinders 610 and 630 away from the center of the fixed chassis 600. One-way valves 760 are fixedly installed on both high-pressure seawater outlet branch pipes 750. A low-pressure seawater inlet pipe 770 is fixedly installed at the connection point of the two low-pressure seawater inlet branch pipes 730. Used to transport low-pressure seawater from the outside into the device, the right end of the low-pressure seawater inlet pipe 770 penetrates the right end of the outer wall of the outer casing 100. A high-pressure seawater outlet pipe 780 is fixedly installed at the connection of two high-pressure seawater outlet branch pipes 750. The left end of the high-pressure seawater outlet pipe 780 penetrates the left end of the outer wall of the outer casing 100 and connects to the high-pressure seawater pipe 200. A one-way valve 790 is fixedly installed on the outer wall of the high-pressure seawater outlet pipe 780. When the cam 680 rotates counterclockwise from the initial point, the piston 650 inside cylinders 2 and 4 compresses the low-pressure seawater inside cylinders 2 and 4 through the connecting pipe 710 into cylinders 1 and 3. Simultaneously, the piston 650 inside cylinders 1 and 3 will... The cam moves closer to the center of the fixed chassis 600, causing cylinders 610 and 630 to draw low-pressure seawater from the connecting pipe 710. As the cam 680 continues to rotate counterclockwise, the pistons 650 inside cylinders 620 and 640 move closer to the center of the fixed chassis 600, causing cylinders 620 and 640 to draw water from the low-pressure seawater inlet branch pipe 730. Simultaneously, the pistons 650 inside cylinders 610 and 630 move away from the center of the fixed chassis 600, causing the low-pressure seawater inside cylinders 610 and 630 to be compressed into high-pressure seawater, which then enters the high-pressure seawater outlet pipe 780 through the high-pressure seawater outlet branch pipe 750. Under the action of the intermediate shaft 410 and the cam 680...The piston 650 within cylinders 610 (cylinder one) and 630 (cylinder three) reciprocates to convert low-pressure seawater into high-pressure seawater.

[0039] In one embodiment, the flow direction of check valve 720 is that seawater flows from cylinder 620 to cylinder 610 or from cylinder 640 to cylinder 630; the flow direction of check valve 740 is that seawater flows into cylinder 620 or cylinder 640; the flow direction of check valve 760 is that seawater flows out of cylinder 610 or cylinder 630; and the flow direction of check valve 790 is that seawater flows from high-pressure seawater outlet pipe 780 into high-pressure seawater pipe 200. One-way valve 720 prevents low-pressure seawater flowing from cylinder 2 620 to cylinder 1 610 or from cylinder 4 640 to cylinder 3 630 from flowing back. One-way valve 740 prevents low-pressure seawater flowing into cylinder 2 620 or cylinder 4 640 from flowing back. One-way valve 760 prevents high-pressure brine flowing out of cylinder 1 610 or cylinder 3 630 from flowing back. One-way valve 790 ensures that high-pressure seawater flowing from high-pressure seawater outlet pipe 780 into high-pressure seawater pipe 200 will not flow back.

[0040] In one embodiment, a fixed frame 800 is fixedly installed on the upper end of the inner wall of the intermediate frame 400 and to the right of the intermediate shaft 410. Cross-shaped fixing brackets 801 are fixedly installed at both ends of the fixed frame 800. A rotating shaft 810 is rotatably connected to the middle of the two cross-shaped fixing brackets 801. A rotating wheel 820 is fixedly installed on the outer wall of the rotating shaft 810 and inside the fixed frame 800. A groove 830 is engraved in the middle of the outer wall of the rotating wheel 820. A [missing information - likely a type of groove] is fixedly installed on the right end of the outer wall of the rotating shaft 810. The propeller blade is 840. A sliding frame 850 is fixedly installed on the lower end of the outer wall of the fixed frame 800. A second sliding groove 860 is opened inside the sliding frame 850. A slider 870 is slidably connected inside the second sliding groove 860. A sliding rod 880 is fixedly installed on the lower end of the outer wall of the slider 870. The upper end of the outer wall of the sliding rod 880 passes through the upper end of the outer wall of the slider 870 and is slidably connected to the first sliding groove 830. An intermediate block 900 is fixedly installed on the lower end of the outer wall of the sliding rod 880. An intermediate block 900 is fixedly installed on the lower end of the outer wall of the intermediate block 900. There is a cleaning plate 910, and an intermediate block 900 is used to connect the sliding rod 880 and the cleaning plate 910. The cleaning plate 910 has an integrally formed opening 920. A brush 930 is fixedly installed on the lower end of the outer wall of the cleaning plate 910. High-pressure brine drives the second propeller blade 840 to rotate, thereby driving the second shaft 810 and the rotating wheel 820 to rotate. When the rotating wheel 820 rotates, it can drive the sliding rod 880 to slide in the first groove 830, thereby driving the sliding rod 880 in the second groove 860. The cleaning plate 910 moves back and forth, causing it to move back and forth. This movement of the cleaning plate 910 drives the brush 930 to scrub and clean the bottom of the inner wall of the middle frame 400. Since concentrated salt water flows through the middle frame 400 and there are a lot of impurities in the seawater, dirt will be generated on the bottom of the inner wall of the middle frame 400. The brush 930 will clean out the dirt and leave the bottom surface of the inner wall of the middle frame 400 through the opening 920, and the dirt particles will be discharged out of the device with the concentrated salt water.

[0041] In one embodiment, the slide 830 is a continuous wave-shaped slide integrally formed on the outer wall of the rotating wheel 820, which enables the rotational motion of the rotating wheel 820 to be converted into the reciprocating linear motion of the moving rod 880.

[0042] In one embodiment, the outer wall of the sliding frame 850 is provided with grooves 860 in both the front-to-back direction and the up-to-down direction, so that both the slider 870 and the sliding rod 880 can slide in the sliding frame 850.

[0043] In one embodiment, the upper ends of the outer walls of the two rotating wheels 660 at cylinder 1 610 and cylinder 2 620 and the two rotating wheels 660 at cylinder 3 630 and cylinder 4 640 are rotatably connected to connecting rods 670. The lower middle parts of the outer walls of the two rotating wheels 660 at cylinder 1 610 and cylinder 4 640 and the two rotating wheels 660 at cylinder 2 620 and cylinder 3 630 are rotatably connected to connecting rods 670, so that the four connecting rods 670 can be alternately connected to the four rotating wheels 660. Thus, when the intermediate shaft 410 rotates and drives the cam 680 to rotate, the four connecting rods 670 can drive the four pistons 650 to perform reciprocating linear motion.

[0044] In one embodiment, the connection points of the rotating wheel 660 and the connecting rod 670 with the cam 680 are coated with grease, which can reduce the friction at the connection points of the rotating wheel 660 and the connecting rod 670 with the cam 680.

[0045] In one embodiment, the brush 930 is a sparse, stiff brush, which can increase the cleaning effect of the brush 930.

[0046] Based on the above scheme, the workflow of the present invention is as follows: In specific use, the high-pressure seawater in the high-pressure seawater pipeline 200 generates fresh water and high-pressure brine in the reverse osmosis membrane module 310. The high-pressure brine enters the intermediate frame 400 through the high-pressure brine pipeline 350. The high-pressure brine can drive the propeller blade 450 to rotate, thereby driving the shaft 440 and bevel gear 460 to rotate, which in turn drives the bevel gear 420 to rotate, causing the intermediate shaft 410 to rotate. When the intermediate shaft 410 rotates, it drives the cam 680 to rotate. When the cam 680 rotates, it slides against the four rotating wheels 660.

[0047] Because of the rotation of cam 680 and the staggered connection of four connecting rods 670, the rotating wheel 660 reciprocates along the straight line formed by its rotation and the center of the fixed chassis 600, thereby driving the four pistons 650 to reciprocate linearly. When cam 680 rotates counterclockwise from the initial point, the pistons 650 inside cylinders two 620 and four 640 compress the low-pressure seawater inside cylinders two 620 and four 640 through the connecting pipe 710 into cylinders one 610 and three 630. At the same time, the pistons 650 inside cylinders one 610 and three 630 move closer to the center of the fixed chassis 600, causing cylinders one 610 and three 630 to draw low-pressure seawater from the connecting pipe 710. As the cam 680 continues to rotate counterclockwise, the piston 650 inside cylinder 2 620 and cylinder 4 640 moves closer to the center of the fixed chassis 600, causing cylinder 2 620 and cylinder 4 640 to draw water from the low-pressure seawater inlet branch pipe 730 and pump it into cylinder 1 610 and cylinder 3 630. The low-pressure seawater in cylinder 1 610 and cylinder 3 630 can be pressurized by piston 650 and delivered to the high-pressure seawater pipe 200. One-way valve 1 720 prevents the low-pressure seawater flowing from cylinder 2 620 to cylinder 1 610 or from cylinder 4 640 to cylinder 3 630 from flowing back, and one-way valve 2 740 prevents the low-pressure seawater flowing into cylinder 2 620 or cylinder 4 640 from flowing back.

[0048] One-way valve 3 760 prevents the high-pressure brine flowing out of cylinder 1 610 or cylinder 3 630 from flowing back. One-way valve 4 790 ensures that high-pressure seawater flowing from high-pressure seawater outlet pipe 780 into high-pressure seawater pipe 200 does not flow back. Furthermore, because concentrated brine flows through intermediate frame 400 and the seawater contains a large amount of impurities, dirt will be generated at the bottom of the inner wall of intermediate frame 400. This high-pressure brine can drive propeller blade 2 840 to rotate, thereby driving shaft 2 810 and rotating wheel 820 to rotate. When the rotating wheel 820 rotates, it drives the sliding rod 880 to slide in the first slide groove 830, thereby driving the sliding rod 880 to reciprocate left and right in the second slide groove 860, which in turn drives the cleaning plate 910 to reciprocate left and right. Through the reciprocating left and right movement of the cleaning plate 910, the brush 930 is driven to scrub and clean the bottom of the inner wall of the middle frame 400. The brush 930 will clean out the dirt and leave the bottom surface of the inner wall of the middle frame 400 through the opening 920, and the dirt particles will be discharged out of the device with the concentrated brine.
