Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to a high-efficiency and energy-saving new energy seawater desalination device. Background Technology

[0002] High-efficiency and energy-saving new energy seawater desalination plants are a comprehensive concept, referring to systems that utilize renewable energy and maximize energy efficiency through advanced technologies to produce freshwater from seawater. Their core objective is to achieve a stable freshwater supply with minimal energy consumption and environmental impact. Before desalination of seawater via reverse osmosis, pretreatment is required to remove large particulate impurities. This pretreatment typically involves a solar-powered pump pressurizing and pumping seawater into a filter tank filled with filter media. The filter media traps impurities as the seawater flows, achieving pre-filtration before desalination. However, due to the high colloidal impurities and pressure of the pre-treated seawater, the media at the end of the filter tank preferentially and persistently traps these impurities. This can lead to blockage and caking of the filter layer, affecting filtration efficiency, stability during desalination, and overall desalination effectiveness. Summary of the Invention

An auxiliary mechanism is installed on the side wall of the sliding mechanism to ensure the flow pressure of seawater during the desalination and filtration process of the sliding mechanism.

[0005] Furthermore, the main body includes: Limiting components are installed inside the filter tank. The elastic component is installed inside the limit component.

[0006] Furthermore, the sliding mechanism includes: A rotating assembly is installed inside the limiting assembly to prevent the filter layer from accumulating during seawater desalination. Telescopic assembly, which is installed on top of rotating assembly.

[0007] Furthermore, the auxiliary mechanism includes a mounting bracket disposed on top of the rotating assembly, and the auxiliary mechanism also includes: The movable component is installed on the side wall of the fixed frame.

[0008] Furthermore, the limiting component includes an inner sleeve that is slidably connected inside the filter tank, and a fixing plate is fixedly connected inside the inner sleeve; The inner sleeve has four supporting frames that slide internally. The inner diameter of the inner sleeve is concave and convex, and the sidewall of the inner sleeve is open.

[0009] Furthermore, the elastic component includes an inner cylinder fixedly connected inside the support frame, and a limit spring fixedly connected to the top of the inner cylinder; The end of the limiting spring furthest from the load-bearing frame is fixedly connected to the bottom of another load-bearing frame, and the end of the topmost limiting spring furthest from the inner cylinder is fixedly connected to the fixing plate. The springs can be made of duplex stainless steel or nickel-based alloy to resist corrosion fatigue.

[0010] Furthermore, the top of the support frame is provided with four curved plates, which are arranged symmetrically in pairs, with the two pairs of curved plates symmetrically distributed around the inner cylinder. The rotating assembly includes a limiting plate that is slidably connected to the front and back of the bending plate, and the limiting plate is fixedly connected to the top of the support frame.

[0011] Furthermore, a second bending plate is provided on the side wall of the first bending plate, and the second bending plate is rotatably connected to the top of the support frame; The telescopic assembly includes protrusions slidably connected to the two side walls of the curved plate, and telescopic rods slidably connected to the side walls of the protrusions.

[0012] Furthermore, the fixing bracket is set on the top of the support frame and is fixedly connected to the inside of the inner sleeve; The bottom of the mounting bracket is fixedly connected to the top of the four telescopic rods; The bottom of the mounting bracket is fixedly connected to four protruding plates; The bottom of the fixed frame is fixedly connected to a fixed sleeve, and two straight grooves are opened on the side wall of the fixed frame. The fixed sleeve is fitted onto the outer surface of the limit spring. The active component includes two sliding shafts that are slidably connected inside the straight groove, and a linear spring is fixedly connected between the two sliding shafts; A rotating plate is rotatably connected to the side wall of the sliding shaft, and the side wall of the rotating plate is in contact with the side wall of the convex plate.

[0013] Furthermore, a desalination process for a high-efficiency and energy-saving new energy seawater desalination device, comprising the following steps: S1: Pipeline connection: First, the staff will install a connecting pipe between the two filter tanks. Then, the top of the first filter tank will be connected to the seawater conveying equipment that needs to be desalinated. At the same time, the outlet of the second filter tank will be connected to the inlet of the main body so that the main body can desalinate the filtered seawater. S2: Placing the filter media: The staff then place the filter media into the interior of multiple carrier frames, and then place the inner sleeve containing the filter media into the filter tank. After that, the external seawater delivery equipment is started. S3: Desalination: When the seawater conveying equipment is working, seawater will surge upward from the bottom of the filter tank. As the seawater surges upward, it will pass through the filter media inside each support frame in turn. At this time, the filter media inside the support frame can intercept impurities in the seawater so that the main body can desalinate it.

[0014] The present invention has the following beneficial effects: 1. In this invention, when the filter media inside one of the support frames becomes caked, the flow of seawater can maintain stable filtration during backwashing, while the filter media inside the other support frames will continue to filter the seawater normally. This reduces the long-term retention of impurities in the seawater by the filter media inside the support frames, thus preventing the filter layer from becoming clogged and caked by impurities, which would affect the filtration efficiency and desalination of the seawater. This ensures the stability of subsequent reverse osmosis desalination and improves the desalination efficiency of the seawater.

[0015] 2. In this invention, the flowing seawater passes through the curved portion at the bottom of the curved plate two and flows towards the side wall of the curved plate one, forming a vortex between the curved plate two and the curved plate one. This ensures that the downward-flowing seawater forms a relatively stable flow at the top of the filter media. At the same time, the seawater is evenly distributed towards the filter media by the reciprocating swing of multiple curved plates one. This reduces the formation of scouring pits on the top of the filter media when the seawater is guided and impacted by the rotating plate after rotation, which can lead to stratification and loss of the filter media, affecting the integrity and filtration intensity of the filter media for seawater filtration.

[0016] 3. The present invention can reduce the up-and-down shaking of the support frame during the pushing and backwashing process of seawater by the friction between the outer surface of the fixed sleeve, the inner wall of the inner sleeve and the protrusion. It can reduce the vibration of the support frame carrying the filter material while ensuring the stability of the filter material in filtering seawater and ensuring the stability of the water quality before seawater desalination.

[0017] 4. This invention, by increasing the flow area between the rotating plate and the inner sleeve, can ensure that the rotating plate guides the backwashing of the filter material after the seawater is tilted, while also ensuring the flow pressure and flow volume of the seawater flowing upward. This improves the continuity and flow intensity of the upward filtration of the rotating plate after it is impacted by the water flow, as some seawater is blocked by the rotating plate. This ensures the stability of the output water during subsequent seawater desalination and further improves the desalination efficiency.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1 - Figure 11 As shown, this invention is a high-efficiency and energy-saving new energy seawater desalination device, including a main body 1, with two filter tanks 101 fixedly connected to the top of the main body 1, and also including: Sliding mechanism 2 is installed inside filter tank 101 and is used to filter seawater before desalination. Auxiliary mechanism 3 is installed on the side wall of sliding mechanism 2 to ensure the flow pressure of seawater during seawater desalination and filtration by sliding mechanism 2.

[0024] Entity 1 includes: Limiting component 11 is installed inside the filter tank 101; The elastic component 12 is installed inside the limiting component 11.

[0025] The sliding mechanism 2 includes: Rotating component 21 is installed inside the limiting component 11 to prevent the filter layer from accumulating during seawater desalination. Telescopic component 22 is mounted on top of rotating component 21.

[0026] The auxiliary mechanism 3 includes a fixing frame 301 disposed on the top of the rotating assembly 21, and the auxiliary mechanism 3 also includes: The movable component 31 is installed on the side wall of the fixed frame 301.

[0027] The limiting component 11 includes an inner sleeve 111 that is slidably connected inside the filter tank 101, and a fixing plate 112 is fixedly connected inside the inner sleeve 111. The inner sleeve 111 has four supporting frames 113 that are slidably connected inside. The inner diameter of the inner sleeve 111 is concave and convex, and the side wall of the inner sleeve 111 is open.

[0028] The elastic component 12 includes an inner cylinder 121 fixedly connected inside the support frame 113, and a limit spring 122 fixedly connected to the top of the inner cylinder 121; Among them, the end of the limiting spring 122 away from the bearing frame 113 is fixedly connected to the bottom of another bearing frame 113, and the end of the topmost limiting spring 122 away from the inner cylinder 121 is fixedly connected to the fixing plate 112. The spring can be made of duplex stainless steel or nickel-based alloy to resist corrosion fatigue. Then, the staff put the filter medium into the interior of multiple bearing frames 113 respectively, and then put the inner sleeve 111 with the filter medium into the filter tank 101.

[0029] The top of the support frame 113 is provided with four curved plates 201. The four curved plates 201 are arranged symmetrically in pairs, and the two pairs of curved plates 201 are symmetrically distributed with the inner cylinder 121 as the center. The rotating assembly 21 includes a limiting plate 211 that is slidably connected to the front and back of the bending plate 201. The limiting plate 211 is fixedly connected to the top of the support frame 113. When the seawater flows downward, the seawater will impact the bending plate 201 downward through the top of the bending plate 201. When the bending plate 201 is impacted by the seawater, the bending plate 201 will slide downward.

[0030] A second bending plate 212 is provided on the side wall of the first bending plate 201, and the second bending plate 212 is rotatably connected to the top of the support frame 113. The telescopic assembly 22 includes a protrusion 221 slidably connected to the side wall of the second bending plate 212. A telescopic rod 222 is slidably connected to the side wall of the protrusion 221. When the second bending plate 212 slides upward, the top of the second bending plate 212 slides inside the protrusion 221. At this time, the telescopic rod 222 will separate from the side wall of the fixed sleeve 302 under the push of the second bending plate 212. Then, when the support frame 113 continues to slide upward, the telescopic rod 222 will be gradually compressed.

[0031] The fixing bracket 301 is disposed on the top of the bearing frame 113 and is fixedly connected to the inside of the inner sleeve 111; The bottom of the mounting bracket 301 is fixedly connected to the top of the four telescopic rods 222; The bottom of the mounting bracket 301 is fixedly connected with four protruding plates; The bottom of the fixing frame 301 is fixedly connected to the fixing sleeve 302. The side wall of the fixing frame 301 has two straight grooves. The fixing sleeve 302 is fitted onto the outer surface of the limiting spring 122. The active component 31 includes two sliding shafts 311 that are slidably connected inside the straight groove, and a linear spring is fixedly connected between the two sliding shafts 311; A rotating plate 312 is rotatably connected to the side wall of the sliding shaft 311. The side wall of the rotating plate 312 is in contact with the side wall of the convex plate. When the seawater continues to flow, the flow of seawater will impact the inclined side wall of the rotating plate 312. When the side wall of the rotating plate 312 is impacted by seawater, the rotating plate 312 will slide in the straight groove through the sliding shaft 311.

[0032] A desalination process for a high-efficiency and energy-saving new energy seawater desalination device, comprising the following steps: S1: Pipeline connection: First, the staff installs a connecting pipe between the two filter tanks 101. Then, the top of the first filter tank 101 is connected to the seawater conveying equipment that needs to be desalinated. At the same time, the outlet of the second filter tank 101 is connected to the inlet of the main body 1 so that the main body 1 can desalinate the filtered seawater. S2: Place the filter media: The staff will then place the filter media into the interior of the multiple carrier frames 113, and then place the inner sleeve 111 with the filter media into the filter tank 101. After that, the external seawater delivery equipment will be started. S3: Desalination: When the seawater conveying equipment is working, seawater will surge upward from the bottom of the filter tank 101. As the seawater surges upward, it will pass through the filter media inside each support frame 113 in sequence. At this time, the filter media inside the support frame 113 can intercept impurities in the seawater so that the main body 1 can desalinate it.

[0033] In use, the operator first installs connecting pipes between the two filter tanks 101. Then, the top of the first filter tank 101 is connected to a pump driven by a solar panel, and the solar-powered pump is connected to the seawater delivery equipment that needs to be desalinated. At the same time, the outlet of the second filter tank 101 is connected to the inlet of the main body 1 so that the main body 1 can desalinate the filtered seawater. Then, the operator puts the filter media into the interior of multiple carrier frames 113, and then puts the inner sleeve 111 with the filter media into the filter tank 101. Then, the external seawater delivery equipment and the solar-powered pump are started. When the seawater delivery equipment is working, seawater will surge upward from the bottom of the filter tank 101. As the seawater surges upward, it will pass through the filter media inside each carrier frame 113 in sequence. At this time, the filter media inside the carrier frame 113 can intercept impurities in the seawater so that the main body 1 can desalinate it.

[0034] After seawater is delivered into the filter tank 101, it flows upward from the bottom. The seawater then passes through the filter media inside the support frame 113 and the space between the two support frames 113. When the filter media becomes caked due to prolonged filtration, the caked media creates significant resistance to the incoming seawater. The continuous inflow of seawater then exerts an upward pushing force on the caked filter media and the support frame 113, causing the support frame 113 to slide upward. As the support frame 113 slides upward, its outer surface separates from the small-diameter area of ​​the inner wall of the inner sleeve 111. At this point, a larger amount of seawater flows through the large-diameter opening of the inner wall of the inner sleeve 111 and between the support frame 113 and the space between the two support frames 113. This inflow of seawater then affects the two sets of rotating... Plate 312 generates a lateral pushing force, at which time a set of rotating plates 312 on both sides of the fixed sleeve 302 will rotate relative to each other. At this time, the rotating plates 312 will guide the incoming seawater. The guided seawater will flow downward through the top of the filter media. The downward flowing seawater will backwash the filter media from the top. At the same time, when the filter media inside one of the support frames 113 is caked, the flow of seawater can maintain stable filtration for backwashing, while the filter media inside the other support frames 113 will continue to filter the seawater normally. This can reduce the long-term retention of impurities in the seawater by the filter media inside the support frames 113, which would cause the filter layer to be blocked and caked by impurities, affecting the filtration efficiency and desalination of seawater. This ensures the stability of subsequent seawater reverse osmosis desalination and improves the desalination efficiency of seawater.

[0035] When seawater impacts the rotating plate 312, causing it to rotate and guiding the seawater, the seawater is guided to impact the filter media downwards from the top area of ​​the support frame 113. As the seawater flows downwards, it impacts the top of the curved plate 201. When the curved plate 201 is impacted by the seawater, it slides downwards. As the curved plate 201 slides downwards, the distance between the curved portion at the top of the curved plate 201 and the curved portion at the bottom of the curved plate 212 decreases. Simultaneously, as the curved plate 201 slides downwards, it can slide to the large-diameter section on the limiting plate 211, at which point the curved plate 201 can swing back and forth. Meanwhile, as the seawater flows downwards after being guided, multiple... The curved plate 201 will swing back and forth on the top of the filter media due to the flow of seawater. At the same time, some seawater will flow downwards. The flowing seawater will flow through the curved part at the bottom of the curved plate 212 to the side wall of the curved plate 201, and form a vortex between the curved plate 212 and the curved plate 201. This can ensure that the downward flowing seawater forms a relatively stable flow on the top of the filter media. At the same time, the seawater will be evenly distributed towards the filter media by the reciprocating swing of multiple curved plates 201. This can reduce the formation of scouring pits on the top of the filter media when the seawater is guided and impacted by the rotating plate 312 after rotation, which would cause the filter media to stratify and lose material, affecting the integrity and filtration intensity of the filter media for seawater filtration.

[0036] When the support frame 113 and the internally plated filter media slide upwards under the push of seawater, the sliding of the support frame 113 will cause multiple curved plates 212 to slide upwards. When the curved plates 212 slide upwards, their tops will slide within the protrusions 221. At this time, the telescopic rod 222 will separate from the side wall of the fixed sleeve 302 under the push of the curved plates 212. Then, as the support frame 113 continues to slide upwards, the telescopic rod 222 will be gradually compressed. Due to the impact of seawater on the plated filter media and the upward sliding of the support frame 113 while flowing through the gap between the support frame 113 and the inner sleeve 111, the flow of seawater impacting and flowing through the gap backwashes the filter media. The flow of seawater at the top and bottom of the support frame 113 easily forms turbulence. At this time, the support frame 113 can appear under the backwashing seawater flow. In the case of downward swaying, when the support frame 113 slides downward in a small initial amplitude, the support frame 113 will drive the second bending plate 212 to slide down synchronously. When the second bending plate 212 slides down, it will slide in the groove inside the protrusion 221 and make the protrusion 221 fit tightly with the fixing sleeve 302. At this time, friction will be formed between the protrusion 221 and the fixing sleeve 302. At the same time, the protrusion 221 near the inside of the inner sleeve 111 will also form friction with the inner wall of the inner sleeve 111. Through the friction between the outer surface of the fixing sleeve 302, the inner wall of the inner sleeve 111 and the protrusion 221, the up-and-down swaying of the support frame 113 during the pushing and backwashing of seawater can be reduced. This can reduce the vibration of the support frame 113 carrying the filter material and ensure the stability of the filter material when filtering seawater, thus ensuring the stability of the water quality before seawater desalination.

[0037] When seawater flows upward through the gap between the inner sleeve 111 and the support frame 113, the upward flow of seawater impacts the rotating plate 312 and causes it to rotate into an inclined state. Subsequently, as the seawater continues to flow, it impacts the side wall of the inclined rotating plate 312. After the side wall of the rotating plate 312 is impacted by seawater, the rotating plate 312 slides in the straight groove through the sliding shaft 311. When the rotating plate 312 slides, it can expand the flow channel between the rotating plate 312 and the inner wall of the inner sleeve 111. By expanding the flow area between the rotating plate 312 and the inner sleeve 111, it can ensure that the rotating plate 312 guides the backwashing of the filter media after the seawater is tilted, while also ensuring the flow pressure and flow volume of the seawater flowing upward. This can improve the continuity and flow intensity of the upward filtration after the rotating plate 312 is impacted by the water flow and some seawater is blocked by the rotating plate 312, ensuring the stability of the output water during subsequent seawater desalination and further improving the desalination efficiency.
