Description

Technical Field

[0001] The present application relates to the technical field of seawater desalination, and in particular to a wave energy capturing and pressurizing device and a seawater desalination system. Background Art

[0002] Desalination, which is the use of seawater to desalinate and produce fresh water, is an open source incremental technology for realizing water resource utilization. It can increase the total amount of fresh water and is not affected by time, space and climate. It can ensure a stable water supply for drinking water for coastal residents and water replenishment for industrial boilers.

[0003] Membrane (RO) is a common method for desalination of seawater. It uses the principle of osmotic pressure. When a pressure greater than the osmotic pressure is applied to the seawater side, the water molecules in the seawater can penetrate through the osmotic membrane to the freshwater side. The ions produced by the salt in the seawater cannot pass through the osmotic membrane due to their large volume, thus separating the water molecules and the salt molecules to obtain fresh water. The production of fresh water in coastal areas usually adopts the traditional membrane desalination method. However, this method requires the configuration of corresponding power sources such as power pumps to pressurize the seawater. It has high energy consumption and high cost, and is difficult to promote on a large scale. Summary of the invention

DETAILED DESCRIPTION

[0058] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection of the embodiments of the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0060] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0061] The embodiment of the present application discloses a wave energy capturing and pressurizing device.

[0062] See also Figure 1 as well as Figure 2 , an embodiment of a wave energy capture boosting device provided in the embodiments of the present application includes:

[0063] The capture cover 106 and the capture bracket 102 , the capture cover 106 includes a main cover body 104 , a first guide cover 103 and a second guide cover 105 .

[0064] The main cover 104 includes a main bottom plate 141, a main back plate 143 and two main side plates 142. The lower side of the main back plate 143 is connected to the rear side of the main bottom plate 141; one side of the two main side plates 142 is respectively connected to the two side edges of the main back plate 143, and the lower sides of the two main side plates 142 are respectively connected to the two side edges of the main bottom plate 141; the two main side plates 142 are symmetrically arranged relative to the main back plate 143, and the distance between them gradually increases in the direction away from the main back plate 143; that is, the main cover 104 is a trumpet-like cover, and has a good wave energy capture ability. The main cover 104 is arranged horizontally to facilitate subsequent drainage. Specifically, the main bottom plate 141 is arranged horizontally, while the main back plate 143 and the main side plates 142 are arranged perpendicular to the main bottom plate 141.

[0065] The first guide cover 103 is connected to the front edge of the main bottom plate 141 away from the main back plate 143 and the side edges of the two main side plates 142 away from the main back plate 143, and is tilted upward relative to the main cover body 104; when sea water surges onto the first guide cover 103, the waves will generate a horizontal acceleration under the oblique guiding action of the first guide cover 103, thereby causing the waves to surge into the main cover body 104 more quickly.

[0066] The second guide cover 105 is an arc-shaped structure, which is connected to the upper sides of the main back plate 143 and the two main side plates 142, and is tilted upward relative to the main cover body 104; the inner arc surface of the second guide cover 105 is a convex arc surface relative to the main bottom plate 141. The design of the second guide cover 105 can capture some waves with a larger surge height, and at the same time offset the excessively strong acceleration of the waves with a larger height hitting the capture cover 106, and convert part of its kinetic energy into an acceleration of centripetal motion, thereby ensuring the stability of the mechanism while further enhancing the wave energy leading to the water hammer mechanism 101.

[0067] The main back plate 143 is provided with a communication port connected to the input end of the water hammer mechanism 101 .

[0068] The wave energy device 100 designed in the present application realizes seawater pressurization based on the water hammer effect and the Pascal principle, does not require an additional power pump, and has lower installation and maintenance costs. In addition, the capture cover 106 is constructed by the main cover body 104, the first guide cover 103, and the second guide cover 105, which can not only accelerate the waves with small wave height to enter the water hammer mechanism 101, but also offset the excessively strong acceleration generated when the waves with large height hit the capture cover 106, ensuring the stability of the mechanism, thereby achieving comprehensive and efficient wave energy capture, greatly reducing the energy consumption and cost of seawater desalination, and facilitating large-scale promotion and application.

[0069] It should be noted that the capture mechanism designed in the present application can not only capture wave energy and ocean current energy, but also capture tides caused by the gravity of the moon.

[0070] The above is an embodiment of the present invention. The following is an embodiment of the present invention. For details, please refer to Figures 1 to 8 .

[0071] Furthermore, if Figure 3 As shown, in order to facilitate drainage, at least one main side plate 142 and / or the main bottom plate 141 is provided with a plurality of drainage gap grooves 144. In the present application, preferably, two main side plates 142 and one main bottom plate 141 are provided with drainage gap grooves 144. In order to reduce the resistance to the instantaneous influx of seawater and to enable smoother and faster drainage, the drainage gap grooves 144 are arranged at an angle, and the end of the drainage gap grooves 144 located on the inner wall of the main cover body 104 is closer to the main back plate 143 than the end located on the outer wall of the main cover body 104.

[0072] Furthermore, if Figure 2 As shown, the first guide cover 103 is designed to include a first guide plate 131 and two connecting side plates 132. The rear side of the first guide plate 131 is connected to the front side of the main bottom plate 141 and is tilted upward. The front side of the first guide plate 131 is located above the rear side of the first guide plate 131. The two connecting side plates 132 are respectively fixed on the two sides of the first guide plate 131, and are connected to the second guide cover 105 body and the side of the main side plate 142 away from the main back plate 143, that is, one connecting side plate 132 connects the second guide cover 105 body on one side with the side of the main side plate 142, and the other connecting side plate 132 connects the second guide cover 105 body on the other side with the side of the main side plate 142, so as to strengthen the connection between the first guide cover 103 and the main cover body 104 and the second guide cover 105, and improve the reliability of the overall structure.

[0073] Furthermore, if Figure 2As shown, the second guide cover 105 includes three arc-shaped second guide plates 151 connected in sequence, and the lower sides of the three second guide plates 151 are respectively connected to the upper sides of the two main side plates 142 and the upper side of the main back plate 143.

[0074] Furthermore, if Figure 2 As shown, it also includes a movable plate 108 and an elastically retractable support member 109.

[0075] The rear side of the movable plate 108 is hinged to the front side of the first guide plate 131; one end of the support member 109 is hinged to the bottom surface of the movable plate 108, and the other end is hinged to the capture bracket 102 or the ground. With this design, when a large wave surges onto the movable plate 108, the support member 109 is compressed by the impact, so that the movable plate 108 is pressed downward, thereby partially relieving the impact force of the wave on the capture cover 106, and at the same time relatively expanding the inlet cross section of the wave energy capture mechanism, further improving the use stability of the capture cover 106 and improving the capture efficiency.

[0076] Furthermore, if Figure 2 as well as Figure 4 As shown, the support member 109 includes a cylinder 191 , a telescopic rod 192 and a support elastic member 193 .

[0077] One end of the cylinder 191 is hinged and fixed, one end of the telescopic rod 192 is movably inserted into the cylinder 191 through the other end of the cylinder 191, and the supporting elastic member 193 is connected between the other end of the cylinder 191 and the other end of the telescopic rod 192.

[0078] Furthermore, if Figure 4 As shown, the support member 109 also includes two connecting gaskets; one of the connecting gaskets is fixed to the other end of the cylinder 191 and allows the telescopic rod 192 to move through; the other connecting gasket is fixed to the other end of the telescopic rod 192; the supporting elastic member 193 can be a spring, specifically a plurality of springs, which are distributed around the circumference of the telescopic rod 192 and fixed between the two connecting gaskets. The two connecting gaskets fix the plurality of supporting elastic members 193, and the design of the plurality of supporting elastic members 193 can provide a more stable elastic force. Of course, a single large-sized supporting elastic member 193 can also be used, which is entirely sleeved on the telescopic rod 192 and then connected to the telescopic rod 192 and the cylinder 191 respectively.

[0079] Furthermore, if Figure 2As shown, taking the design of the movable plate 108 as an example, an extension portion 133 is additionally provided on one side of the connecting side plate 132 away from the main side plate 142, the lower side of the extension portion 133 can be in contact with the movable plate 108, and there is a certain gap between the upper side of the extension portion 133 and the second guide cover 105. The extension portion 133 can reduce the wave loss at the movable plate 108, but at the same time, the gap formed can increase the drainage capacity to a certain extent.

[0080] Furthermore, if Figure 5 As shown, the capture bracket 102 includes a front bracket 123 and a rear bracket 124 .

[0081] The front bracket 123 includes a support plate 121 and a support rod 122. The support rod 122 is connected between the support plate 121 and the first guide cover 103, or between the support plate 121 and the main cover body 104. The support plate 121 contacts the sand and is then connected through the support rod 122 to achieve front support.

[0082] The rear support 124 is a Z-shaped structure, the top of which is connected to the bottom of the main cover 104, and the tail can be shaped like an anchor, which can be buried in the sand to achieve rear support.

[0083] Furthermore, if Figure 6 As shown, the water hammer mechanism 101 includes a main pump pipe 111 .

[0084] One end of the main pump pipe 111 is connected to the main cover body 104, and a pressure relief float 112 is installed on the other end; a boost pipe 113 is provided on the pipe wall of the main pump pipe 111; a boost float 114 is installed in the boost pipe 113; a boost output pipe 115 is connected to the pipe wall of the boost pipe 113 above the boost float 114; the cross-sectional area of ​​the boost pipe 113 is smaller than that of the main pump pipe 111, and specifically can be one third of the cross-sectional area of ​​the main pump pipe 111; the cross-sectional area of ​​the boost output pipe 115 is smaller than that of the boost pipe 113, and specifically can be one tenth of the cross-sectional area of ​​the boost pipe 113.

[0085] like Figure 7 As shown, a conical pressure relief port 1161 is provided on the other end of the main pump pipe 111, and a plurality of first protrusions 1181 are arranged below the pressure relief port 1161 and are circumferentially distributed in the other end of the main pump pipe 111, and can contact and abut against the bottom of the pressure relief float 112. A first limiting ring 1171 is fixed on the top of the first protrusion 1181, and a gap connecting the pressure relief port 1161 is formed between the first limiting ring 1171 and the main pump pipe 111, and the pressure relief float 112 is movably arranged in the first limiting ring 1171. Figure 8As shown, a boost port 1162 in the shape of an inverted cone is opened at the lower end of the boost pipe 113, and a plurality of second protrusions 1182 which are distributed circumferentially and can contact and abut against the top of the boost float 114 are arranged in the boost pipe 113 above the boost port 1162, and a second limiting ring 1172 is fixed to the bottom of the second protrusion 1182, and a gap connecting the boost port 1162 is formed between the second limiting ring 1172 and the boost pipe 113, and the boost float 114 is movably installed in the second limiting ring 1172.

[0086] After the seawater flows into the main pump pipe 111, it first flows to the pressure relief port 1161, and then impacts the pressure relief float 112 to drive the pressure relief float 112 to move. The pressure relief float 112 is impacted and moves to block the pressure relief port 1161, and the seawater will flow to the pressure boosting port 1162; the water hammer effect is utilized here. When the water flow is suddenly cut off, its kinetic energy will be applied to the pressure boosting float 114, thus realizing the first stage of seawater pressurization.

[0087] The seawater then impacts the boosting float 114, lifts up the boosting float 114, and then flows into the boosting pipe 113 from the gap formed between the second limit ring 1172 and the boosting pipe 113; the Pascal principle is used here, when the boosting float 114 is pushed up, the gap formed between the second limit ring 1172 and the boosting pipe 113 is connected to the boosting port 1162, and because the cross-sectional area of ​​the boosting pipe 113 is much smaller than the cross-sectional area of ​​the main pump pipe 111, the pressure of this part of the seawater flowing through the boosting port 1162 is increased, thereby achieving the second-level seawater boosting; taking the cross-sectional area of ​​the boosting pipe 113 as one-third of the cross-sectional area of ​​the main pump pipe 111 as an example, the pressure can be increased three times.

[0088] After entering the boosting pipe 113, the seawater is output from the boosting output pipe 115 with a smaller cross-sectional area to achieve the third-stage seawater boosting. If the cross-sectional area of ​​the boosting output pipe 115 is one tenth of the cross-sectional area of ​​the boosting pipe 113, the pressure can be increased tenfold, that is, the pressure increase is completed thirty times. Of course, the ratio between the cross-sectional areas can be changed according to actual needs to achieve a better boosting effect.

[0089] The present application also discloses a seawater desalination system, including a pretreatment device, a reverse osmosis device, and the wave energy capture and pressurization device of the above-mentioned embodiment 1 or embodiment 2.

[0090] The pretreatment device is connected to the wave energy capture and boosting device, and is used to pretreat the seawater delivered by the wave energy capture and boosting device into raw water; the reverse osmosis device is connected to the pretreatment device, and is used to desalinate the raw water delivered by the pretreatment device.

[0091] The above is a detailed introduction to a wave energy capture and boosting device and a seawater desalination system provided by the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and the scope of application. In summary, the content of this specification should not be understood as a limitation on the present application.
