Description

Technical Field

[0001] This application relates to the field of water purification device technology, and in particular to a concentrated evaporation water purification device. Background Technology

[0002] Given the uneven distribution of global water resources and severe water shortages in some areas, access to clean and usable freshwater resources has become a critical issue for ensuring human survival and development. This is especially true in remote mountainous regions and areas affected by natural disasters, where traditional freshwater supply methods are limited. Common purification technologies for rainwater and well water include reverse osmosis and electrodialysis. While reverse osmosis technology is widely used, it requires high-pressure pumps, resulting in high energy consumption. Furthermore, the membrane modules are susceptible to fouling and clogging, leading to performance degradation and increased replacement costs. Electrodialysis technology has high requirements for feed water quality and also consumes relatively large amounts of energy.

[0003] Therefore, there is an urgent need for a high-efficiency, energy-saving and structurally sound concentrated evaporation water purification device to improve the utilization efficiency of solar energy and the evaporation and condensation effect. Utility Model Content

[0018] The beneficial effects that this application can achieve are: This application discloses a concentrated solar evaporation water purification device. By incorporating a reflector, solar energy is concentrated on a specific area of ​​the evaporator. Compared to traditional methods that rely on large-area solar energy reception, the amount of solar energy received per unit area is significantly increased. This allows for faster and more efficient heat transfer to the water to be evaporated within the evaporator, significantly improving solar energy utilization efficiency and accelerating the heating speed of the evaporator. The reflector concentrates light to form a spot that heats the evaporator. Evaporation of the water does not require connection to the municipal power grid, thus expanding its applicability. A steam pipe connected to the evaporation chamber provides a dedicated steam transmission channel. After generation, the steam flows smoothly along the pipe to the condenser, preventing disordered diffusion and accumulation of steam within the device. This reduces heat exchange and secondary pollution, ensuring steam purity. This application consists of three main parts: the evaporator, the reflector, and the condenser. Each part has a clearly defined function and a relatively independent structure. This modular design allows for flexible combination and layout during installation according to actual needs, reducing installation difficulty and cost. At the same time, it facilitates individual inspection and repair of each component during maintenance, improving the maintainability of the device. Attached Figure Description

[0026] Example 1 Reference Figures 1-7 The first embodiment of this application provides a concentrated evaporation water purification device, comprising: Evaporator 20 has an evaporation chamber 21 and is provided with a steam pipe 40 communicating with the evaporation chamber 21; The reflector 10 is used to reflect light and project the formed light spot onto the outer wall of the evaporator 20 to heat the evaporator 20, so that the water to be evaporated inside the evaporator 20 is heated and evaporated. The condenser 50 has an inlet end and an outlet end. The inlet end is used to connect to the steam pipe 40, and the outlet end is used to discharge the liquid after the steam is condensed.

[0027] In this embodiment, the upper surface of the reflector 10 is a reflective surface, which can be set as a paraboloid of revolution or a composite paraboloid to ensure that the incident light rays converge to a single focal point (or focal line) after reflection, forming a high-density focused light spot. The reflector 10 can be a single integral structure or it can be spliced ​​together from multiple small curvature units. Each unit can be independently adjusted in angle (error ≤ 0.1°), and the splicing error is compensated by an algorithm to ensure overall focusing accuracy. A high reflectivity coating is provided on the upper surface of the reflector 10. The substrate of the reflector 10 can be a lightweight aluminum alloy (such as 6061-T6) or carbon fiber composite material, with a silver or silica antireflective film plated on the surface. The evaporator 20 can actually be a container, and the material to be heated can be water. The shell of the evaporator 20 can be configured as a double-layer structure, with a sandwich space formed between the two layers. The sandwich space is in a relatively sealed state, and it can play a certain role in heat preservation. Furthermore, heat preservation material can be filled into the sandwich space to improve the heat preservation effect of the shell of the evaporator 20.

[0028] The upper end of the evaporator 20 can be equipped with an openable and closable cover plate 32. Water to be heated can be injected into the evaporator 20 by opening the cover plate 32. Alternatively, a water inlet pipe can be installed on the evaporator 20 to inject water into it. A steam pipe 40 installed on the evaporator 20 is used to evaporate the water inside the evaporator 20 when it is heated. The generated steam can be transported through the steam pipe 40 to the condenser 50 for condensation to obtain purified water. The purified water can then be delivered to its destination for use by people or livestock according to actual needs. In this embodiment of the concentrated evaporation water purification device, "concentration" refers to the formation of a focused light spot by reflecting light through the reflector plate 10, and "evaporation" refers to the evaporation of the water inside the evaporator 20 by heating it. The evaporator 20, reflector plate 10, and condenser 50 are modularly designed, and the structures of the three parts are relatively independent. This modular design allows the device to be flexibly combined and laid out according to actual needs during installation, reducing installation difficulty and cost, and also facilitating repair or replacement if one part fails.

[0029] Example 2 Based on Embodiment 1, this embodiment provides a water replenishment structure for the water to be evaporated in the evaporator 20, including a water storage tank 30, a water storage cavity 31 in the water storage tank 30, the water storage cavity 31 for containing the water to be evaporated, a condenser 50 disposed in the water storage cavity 31, the water to be evaporated in the water storage cavity 31 can exchange heat with the condenser 50, and a water replenishment pipe 70 is provided between the water storage tank 30 and the evaporator 20 so that the water to be evaporated in the water storage cavity 31 can enter the evaporator 20 through the water replenishment pipe 70.

[0030] Specifically, the water storage chamber 31 within the water storage tank 30 is used to hold the water to be evaporated. This water can be rainwater, well water, municipal water supply, or water purified by the previous system (multiple concentrated evaporation water purification devices work together to achieve multi-stage purification). An inlet pipe can be installed on the water storage tank 30 to allow the water to be evaporated to enter the tank. The condenser 50 is located within the water storage tank 30, and the water to be evaporated in the tank must at least submerge a portion of the condenser 50. Preferably, the evaporator 20 completely submerges the condenser 50. The water to be evaporated in the water storage tank 30 is used for heat exchange with the condenser 50, condensing the steam inside the condenser 50 and liquefying the water vapor. After the water to be evaporated in the water storage tank 30 undergoes heat exchange in the condenser 50, it can achieve the effect of preheating the water to be evaporated, so that the water temperature delivered to the evaporator 20 through the water supply pipe 70 is increased. Compared with the water to be evaporated being delivered directly to the evaporator 20 without going through the heat exchange in the water storage tank 30, the heat required for the vaporization of the water to be evaporated can be reduced, and the heat of the water vapor generated by the evaporator 20 can be used more reasonably.

[0031] It should be noted that a float valve 23 can be installed at the inlet pipe inside the water storage tank 30. This float valve 23 can automatically open and close the inlet pipe based on the water level in the water storage tank 30, allowing for automatic water replenishment when the water level drops. A solenoid valve can also be installed at the inlet pipe to control the water inflow according to actual usage needs. A perforated cover 32 can be installed at the top of the water storage tank 30 to collect rainwater. A float valve 23 can also be installed inside the evaporator 20 to automatically replenish water to the evaporator 20 through the water supply pipe 70.

[0032] Optionally, the outer wall of the water supply pipe 70 is provided with a heating element (not shown in the figure), and the outer wall of the water storage tank 30 is provided with a photovoltaic module 60. The heating element is configured to be powered by the photovoltaic module 60 and / or the municipal power grid to heat the water supply pipe 70.

[0033] Specifically, a photovoltaic module 60 is installed on the outer wall of the water storage tank 30. The photovoltaic module 60 can be equipped with a battery and an inverter, etc. Under sufficient sunlight, it can generate electricity, which is then supplied to a heating element. The heating element is a heating wire that can be wound around the outer wall of the water supply pipe 70. The power supply principle of the photovoltaic module 60 is based on the photoelectric effect of semiconductor materials. Its core process involves photons exciting electron-hole pairs, using the built-in electric field of the PN junction to separate charges, and ultimately converting solar energy into electrical energy. When the power supply from the photovoltaic module 60 is insufficient, the heating element can be powered by the municipal power grid.

[0034] When the outdoor temperature is low and the water supply pipe 70 freezes, the heating element can heat the water supply pipe 70 to thaw it, ensuring that the water to be evaporated in the water storage tank 30 can be transported to the evaporator 20 through the water supply pipe 70. The heating element can also heat the water flowing through the water supply pipe 70 to preheat the water entering the evaporator 20 for evaporation.

[0035] Optionally, the water storage tank 30 is connected to a water injection pipe, and a float valve 23 is provided at one end of the water injection pipe located in the water storage chamber 31 and / or at one end of the water supply pipe 70 located in the evaporator 20.

[0036] Specifically, the water injection pipe is used to replenish the water to be evaporated into the water storage tank 30. The water injection pipe can be connected to the municipal water network, or to well water, river water, etc. A water pump is installed on the water injection pipe to pump well water or river water into the water storage tank 30.

[0037] Optionally, a cover plate 32 is provided at the upper end of the water storage tank 30. The cover plate 32 has multiple through-holes that are connected to the water storage cavity 31.

[0038] Specifically, a cover plate 32 is provided, with its first end hinged to the upper end of the water storage tank 30, and its second end able to rotate around the first end to open and close the upper end of the water storage tank 30. This facilitates maintenance and repair of the water storage tank 30, and also allows workers to directly pour water into the tank 30 for purification by opening the cover plate 32. Multiple flow holes are provided on the cover plate 32 to collect rainwater, allowing it to enter the water storage tank 30 as water to be evaporated.

[0039] Optionally, the condenser 50 includes a first manifold 51 and a second manifold 52. The first manifold 51 and the second manifold 52 are hollow structures. The inlet end is configured on the first manifold 51 and the outlet end is configured on the second manifold 52. The first manifold 51 and the second manifold 52 are interconnected by a plurality of condenser tubes 53.

[0040] Specifically, the first manifold 51 is located at the upper end of the condenser tube 53, and the second manifold 52 is located at the lower end of the condenser tube 53. The first manifold 51 has a hollow structure, and its interior forms a first collecting cavity. The second manifold 52 forms a second collecting cavity. The two ends of the condenser tube 53 are connected to the first and second collecting cavities, respectively. The water vapor generated inside the evaporator 20 is transported to the first collecting cavity through the steam pipe 40, and then to the second collecting cavity through the condenser tube 53. Finally, it is discharged from the condenser 50 through the outlet pipe 54. By setting multiple condenser tubes 53, the contact area between the condenser 50 and the water to be evaporated is increased, thereby improving the heat exchange efficiency between the condenser 50 and the water to be evaporated. The condensate discharged from the outlet end of the condenser 50 is discharged outside the water tank.

[0041] Optionally, the outlet end is connected to a water outlet pipe 54, which penetrates the side wall of the water storage tank 30. The water outlet end of the water outlet pipe 54 can be connected to at least one of the water-using equipment, the water purification container 55, and the water supply pipeline.

[0042] Specifically, the water-using equipment can be a faucet, and the water purification container 55 can be a water bottle or a water tank. When multiple concentrated evaporation water purification devices are used in conjunction to achieve multi-stage evaporation, the water supply pipeline can be a pipe connecting to the next-stage water storage tank 30. A placement rack 100 can be installed at the lower end of the water storage tank 30, with multiple placement surfaces at different heights. The water storage tank 30 can be placed on the upper placement surface, and the water purification container 55 can be placed on the lower placement surface, so that the water purification container 55 can be replaced when it is full. The placement rack 100 can also be equipped with multiple steps, so that staff can walk up to the upper part of the placement rack 100 to perform operations such as refilling water and maintenance on the water storage tank 30.

[0043] Optionally, the side walls of the water tank 30 are made of thermal insulation material.

[0044] Specifically, the water storage tank 30 may include a box structure made of aluminum or stainless steel, and the outer surface of the box structure may be covered with at least one of polyurethane foam, phenolic foam, and vacuum insulation panels. By setting the water storage tank 30 as an insulated water storage tank 30, the water vapor generated by the evaporator 20 enters the condenser 50, which allows the water in the water storage tank 30 to be heated to a certain extent, reducing heat loss from the water in the tank and keeping the water temperature in the tank above 0 degrees Celsius, thereby preventing the water in the tank from freezing and thus preventing damage to the water tank or the float valve 23 inside the water tank from freezing.

[0045] Example 3 Based on Embodiment 1, this embodiment provides a specific structure of a rotating assembly, including: the rotating assembly includes a positioning member 80, a rotating shaft 81, and a support frame 90; the positioning member 80 has a positioning hole 88, a portion of the rotating shaft 81 is located in the positioning hole 88, and the rotating shaft 81 can rotate around the axis of the positioning hole 88; the rotating shaft 81 is connected to the reflector plate 10, and the evaporator 20 is connected to the rotating shaft 81 through the support frame 90.

[0046] Specifically, the positioning component 80 supports the entire reflector 10 and evaporator 20. The positioning component 80 can be positioned as needed by means of placement, screw fixing, etc. The upper end of the positioning component 80 has a positioning hole 88, and the lower end of the rotating shaft 81 is located within the positioning hole 88, allowing the rotating shaft 81 to rotate within it. Optionally, a bearing seat can be provided inside the positioning hole 88 or outside the positioning component 80, with a bearing installed inside. The bearing hole is coaxial with the positioning hole 88, and a portion of the rotating shaft 81 is mounted within the bearing, improving the stability of the rotating shaft 81 during rotation. The lower end of the support frame 90 is connected to the rotating shaft 81, and the upper end of the support frame 90 is connected to the evaporator 20. It should be noted that both the steam pipe 40 and the water supply pipe 70 can be flexible hoses. When the reflector 10 and the evaporator 20 are driven to rotate synchronously by the rotating assembly, the steam pipe 40 and the water supply pipe 70 can bend adaptively. It should also be noted that the rotating assembly will not always rotate in one direction to avoid the steam pipe 40 and the water supply pipe 70 interfering with the rotation of the rotating assembly.

[0047] Optionally, the rotating assembly also includes a mounting bracket 87 for supporting the reflector 10, and the mounting bracket 87 is connected to the rotating shaft 81.

[0048] Specifically, the fixing frame 87 includes multiple horizontally and vertically intersecting fixing beams. The fixing beams are connected to the lower end of the reflector 10, and the shape of the fixing beams matches the lower arc surface of the reflector 10. The fixing beams increase the support area for the lower end of the reflector 10, thereby improving the support stability of the reflector 10. The fixing frame 87 can be connected to the reflector 10 by means of bonding, welding, bolting, etc.

[0049] Optionally, a first gear 82 is fitted on the positioning component 80, a mounting plate 83 is connected to the rotating shaft 81, a drive motor 84 is provided on the mounting plate 83, a second gear 85 is fitted on the output shaft of the drive motor 84, the second gear 85 meshes with the first gear 82, and the drive motor 84 drives the rotating shaft 81 to rotate around the positioning hole 88 of the positioning component 80.

[0050] Specifically, the first gear 82 is sleeved on the positioning member 80. The portion of the positioning member 80 where the first gear 82 is sleeved is cylindrical. The first gear 82 is fixedly mounted on the positioning member 80, meaning it will not rotate relative to the positioning member 80. A mounting plate 83 is provided on the rotating shaft 81, and the mounting plate 83 is fixedly connected to the rotating shaft 81. There is no relative movement between the mounting plate 83 and the rotating shaft 81. The mounting plate 83 supports the drive motor 84, allowing the output shaft of the drive motor 84 to be located outside the first gear 82. The second gear 85 is mounted on the output shaft of the drive motor 84, parallel to the first gear 82, and located outside the first gear 82. The second gear 85 meshes with the first gear 82. When the drive motor 84 operates, the second gear 85 moves circumferentially around the outer periphery of the first gear 82. That is, the first gear 82 remains stationary, while the second gear 85 moves circumferentially around the first gear 82, thereby driving the rotating shaft 81 to rotate circumferentially via the mounting plate 83. The drive motor 84 can be equipped with photoelectric encoders, etc., and the start, stop, speed, etc. of the drive motor 84 can be logically controlled according to actual usage requirements.

[0051] Optionally, a counterweight 86 is also provided on the mounting plate 83, with the counterweight 86 and the drive motor 84 located on opposite sides of the rotating shaft 81.

[0052] Specifically, a counterweight 86 is installed on the mounting plate 83. The weight of the counterweight 86 is approximately equal to the weight of the drive motor 84, ensuring that the weight on both ends of the mounting plate 83 is roughly the same. This prevents the shaft from being unbalanced on one side, which would result in greater friction on one side during rotation and affect rotational stability. The counterweight 86 can also be configured as a battery to power the drive motor. The battery can be charged via the municipal power grid.

[0053] Optionally, the support frame 90 includes a first connecting rod 93, a second connecting rod 94, a first support rod 91, and a second support rod 92; the first end of the first support rod 91 is connected to the rotating shaft 81, one end of the first connecting rod 93 is connected to the second end of the first support rod 91, and the other end of the first connecting rod 93 is connected to the evaporator 20; the first end of the second support rod 92 is connected to the rotating shaft 81, one end of the second connecting rod 94 is connected to the second end of the first support rod 91, and the other end of the second connecting rod 94 is connected to the evaporator 20.

[0054] Specifically, the first support rod 91 and the second support rod 92 are located on both sides of the rotating shaft 81, and both the first support rod 91 and the second support rod 92 are inclined upwards. The lower end of the second support rod 92 is fixed to the rotating shaft 81. Compared with directly connecting the lower ends of the first connecting rod 93 and the second connecting rod 94 to the rotating shaft 81, by setting the first support rod 91 and the second support rod 92, the connection position of the lower ends of the first connecting rod 93 and the second connecting rod 94 is offset to the periphery of the rotating shaft 81, thereby improving the stability of the mounting bracket supporting the evaporator 20.

[0055] The reflector 10 is tilted and mounted on the rotating assembly. Both the reflector 10 and the evaporator 20 are mounted on the rotating assembly. The rotating assembly drives the reflector 10 and the evaporator 20 to move synchronously. When the evaporator 20 is mounted on the reflector 10, through experience and multiple trials, the light spot reflected by the reflector 10 is projected onto the bottom outer wall or side wall of the evaporator 20. During the rotation of the rotating assembly, the reflector 10 and the evaporator 20 do not rotate separately, and there is no relative movement between them. This eliminates the need to adjust the position of the evaporator 20 each time, reducing manual labor intensity. As the reflector 10 is driven to rotate by the rotating assembly, the relative angle of the reflector 10 can be adjusted in real time to track changes in the solar azimuth and altitude angles over time, maintaining the angle of sunlight incidence within a suitable range to improve the heat collection efficiency of the evaporator 20.

[0056] It should be noted that during the process of the reflector 10 rotating to chase the light, the light chasing can be targeted at only a certain time period or multiple preset time periods, without needing to chase the light all day long when there is no sunlight; of course, it can also chase the light all day long.

[0057] The device's geographical location (longitude and latitude) and time information are obtained via a GPS module. Combined with a solar position algorithm (such as the SPA algorithm), the theoretical solar azimuth and altitude angles are calculated as a tracking reference. A four-quadrant photodetector or CCD camera is installed on the outer wall of the evaporator 20 to monitor the deviation of the light spot center position in real time (accuracy ±0.5mm). The theoretical values ​​are corrected using a PID algorithm to compensate for mechanical errors and environmental interference (such as uneven ground). In clear weather: a high-speed tracking mode (azimuth and rotation speed 2-5 rpm) is used to quickly respond to solar motion (angular velocity 0.25° / min). In cloudy weather: a low-speed cruise mode is switched (azimuth and rotation speed 0.5-1 rpm) to reduce energy consumption and wear caused by frequent motor start-stop. Combining historical weather data and a solar trajectory model, the reflector angle is pre-adjusted by 1010 degrees 10-15 minutes in advance to shorten the tracking delay (delay time ≤0.3s).

[0058] Optionally, the support frame 90 further includes a support ring 96 and a pull rod 95. The support ring 96 has a mounting surface for mounting the evaporator 20. The first support rod 91 is a telescopic member. The first end of the first support rod 91 is hinged to the rotating shaft 81, and the second end of the first support rod 91 is hinged to one end of the first connecting rod 93. The other end of the first connecting rod 93 is hinged to the support ring 96. One end of the pull rod 95 is hinged to the rotating shaft 81, and the other end is hinged to the middle of the first connecting rod 93. One end of the second connecting rod 94 is hinged to the support ring 96, and the other end of the second connecting rod 94 is hinged to the support ring 96. The angle between the mounting surface of the support ring 96 and the horizontal plane can be adjusted by driving the first support rod 91.

[0059] Specifically, the first end of both the first support rod 91 and the second support rod 92 connected to the rotating shaft 81 is designated as the first end, and the second ends of both the first support rod 91 and the second support rod 92 are located away from the first end. The first support rod 91 is a telescopic component, which can be one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The two ends of the first support rod 91 are hinged to the first connecting rod 93 and the rotating shaft 81, respectively. The support ring 96 is used to support the evaporator 20. The support ring 96 can be a ring structure to ensure support stability while preventing the support ring 96 from blocking the light-gathering plate from projecting onto the lower outer wall of the evaporator 20. The support ring 96 can be connected to the evaporator 20 by means of bonding, welding, riveting, bolting, etc. The upper end of the second connecting rod 94 is hinged to the support ring 96, and the lower end of the second connecting rod 94 is connected to the second end of the second support rod 92. The first connecting rod 93 can be Y-shaped, with the upper end of the Y-shape connected to the support ring 96 and the lower end of the Y-shape connected to the first support rod 91. By setting a pull rod 95, the stability of the first connecting rod 93 is improved. The two ends of the pull rod 95 are hinged to the first connecting rod 93 and the rotating shaft 81, respectively. It should be noted that the aforementioned hinge typically includes a hinge axis, through which the two hinged components can rotate relative to each other around the hinge axis. When the first support rod 91 extends, ... Figure 3 For reference, the left end of the support ring 96 is tilted upwards and to the right. At this time, the right end of the support ring 96 will also move slightly to the right. During this adjustment, each hinged part undergoes adaptive adjustment around the hinge axis. It should be noted that the hinges are damped connections; that is, when rotating around the hinge axis at the hinge, a certain amount of damping needs to be overcome to ensure that the hinges do not rotate arbitrarily when the first support rod 91 does not extend or shorten. Similarly, when the first support rod 91 shortens... Figure 3 For reference, the left end of the support ring 96 is tilted downwards and to the left. At this time, the right end of the support will also move slightly downwards and to the left instead of remaining stationary. This allows the tilt angle of the upper surface of the support ring 96 to be adjusted via the first support rod 91 according to actual usage requirements, thereby adjusting the tilt angle of the lower surface of the evaporator 20. This enables the focused light spot to be projected directly onto the bottom wall of the evaporator 20 when the reflector of the reflector plate 10 drifts, by finely adjusting the tilt angle of the lower outer wall of the evaporator 20.

[0060] Optionally, the positioning element 80 includes a positioning post, a positioning hole 88 is configured on the upper end of the positioning post, and a plurality of legs are provided on the lower end of the positioning post.

[0061] Specifically, by setting multiple support legs, the support coverage area of ​​the positioning component 80 is increased, thereby improving support stability.

[0062] Optionally, the evaporator 20 is located above the reflector 10, which has a through clearance hole for the support frame 90 to pass through.

[0063] Specifically, clearance holes are provided to facilitate the installation of the first connecting rod 93, the second connecting rod 94, the pull rod 95, and the second support rod 92.

[0064] Optionally, the evaporator 20 is provided with heat-conducting fins 22 inside the evaporation chamber 21. By providing heat-conducting fins 22, the heat from the bottom wall of the evaporator 20 can be transferred more evenly to the water to be evaporated in the evaporation chamber 21.

[0065] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
