Description
Technical Field
The invention relates to the technical field of solar energy light-gathering power generation and seawater desalination and utilization. In particular to a novel structure combining an inflatable underwater solar condenser, a solar cell panel and a distillation type seawater desalination device.
Background
The sun is the source of the earth's life, about 5.5 × 10 per day21kJ solar energy reaches the earth. The vast majority of this energy is absorbed by the 71% of the ocean's surface area. However, when designing the existing devices using solar energy, only how to install and use the devices on land is often considered, so that the devices are not suitable for oceans, and a great deal of solar energy in oceans is wasted.
In recent years, people have a tendency toward the ocean, and the exploration on the ocean is more and more, so that not only are the number of waterborne aircrafts increasing, but also the number of underwater submergence vehicles or underwater working devices is increasing along with the deepening of underwater exploration, so that the problems of energy supply and domestic water supply of the submergence vehicles or the underwater working devices are gradually brought to the front of people. At present, people mainly rely on a base station or a supply ship to charge or supplement energy for devices such as a submarine, and the activity space of the submarine is greatly limited. It would clearly be of great interest if the submersible could be charged using natural energy nearby. In the ocean, there are many natural energies, such as temperature difference energy of seawater, ocean current kinetic energy, tidal energy, and abundant solar energy on the sea surface. However, the temperature difference of the ocean is only about 25 ℃, and the temperature difference generating efficiency is very low, so that it seems infeasible to provide larger power for the underwater vehicle by utilizing the temperature difference generating; power generation from ocean currents and tidal energy can be highly efficient but requires bulky equipment which is not permissible for the confined space of a submersible vehicle to carry such bulky equipment.
Since the density of underwater sunlight has become very low, if ordinary photovoltaic cells are used to generate electricity, a large cell area is required, which is not a condition for permission, nor is it necessary. The solar energy collecting device can collect the underwater sunlight, realize underwater light collection and reduce the use amount of batteries. In addition, the seawater can be heated by using the waste heat generated by the solar cell panel, so that the seawater is distilled to generate fresh water. The combined device not only realizes the comprehensive utilization of solar energy thermoelectric power and improves the utilization rate of solar energy, but also solves the difficult problems of electricity utilization and water utilization of personnel on the underwater vehicle. Therefore, it becomes necessary to develop an underwater light-collecting device.
Disclosure of Invention
The invention provides a device combining an inflatable condenser, a solar battery pack and a distillation seawater desalination system, which utilizes solar energy to generate electricity and produce fresh water. The composite device works under seawater, so that the influence of sea strong wind on the system operation is small, and the performance of resisting severe weather is strong. The inner side of the inner wall of the inflatable condenser is plated with the reflecting film, and the refractive index of seawater outside the inner wall is larger than that of air inside the condenser, so that even if part of light rays penetrate through the reflecting film, the light rays are totally reflected as long as the incident angle of the light rays is larger than the critical angle, and the utilization rate of the entering light rays is improved by the condenser utilizing the light rays collected by reflection and total reflection. When the system is in a non-working state, the flexible inflatable condenser interlayer discharges gas, and the condenser can be folded and reduced, so that the whole system is convenient to carry and store. The whole system not only utilizes solar energy to generate electric energy, but also utilizes the waste heat generated in the power generation process of the solar cell panel to distill and desalt seawater, thereby improving the energy utilization rate of the system.
An inflatable underwater solar light-gathering power generation and seawater desalination composite device mainly comprises a flexible inflatable light-gathering device, an inflation valve, a solar panel device, a condenser, a guide pipe, an air inlet and outlet valve and a fresh water storage box.
The technical scheme and the working principle adopted by the invention are as follows: the flexible inflatable condenser can be filled with gases with different masses to adapt to underwater pressures at different depths, and a large number of vent hole limiting diaphragms arranged in the flexible inflatable condenser can limit the relative positions of two outer surfaces of the condenser so as to ensure that the surfaces of the condenser are not excessively protruded outwards after the condenser is filled with the gases, so that the condenser can keep a proper composite paraboloid shape. When light rays obliquely incident or parallel to the symmetry axis of the condenser enter underwater, are reflected by the coating surface of the flexible inflatable condenser or are reflected for multiple times and then are collected on the solar panel, and the solar panel converts light energy into electric energy to be output outwards due to the photovoltaic effect; when the electric energy is generated, the waste heat generated by the solar cell panel is led out from the back of the solar cell panel, so that the aim of cooling the solar cell panel to heat the seawater is fulfilled. Because the condenser and the fresh water storage box are connected by the conduit, the amount of gas in the condenser can be controlled by the air intake and exhaust valve on the fresh water storage box, so that the free liquid level formed in the condenser just submerges the upper end of the solar panel and does not exceed the lowest point of the fine through hole of the ventilation water collector. The seawater on the back of the cell panel generates steam at the free liquid level inside the condenser after being heated, and the steam enters the condenser through the thin through hole on the air and water collector. Because the temperature of the seawater on the outer wall of the condenser is lower, the high-temperature steam entering the condenser is condensed on the inner wall of the condenser to form fresh water drops. Under the action of gravity, the water drops flow through a conduit with one end connected with the fresh water storage box along the upper channel of the ventilation water collector and finally are collected into the fresh water storage box.
In addition, because the refractive index of the gas in the interlayer of the inflatable underwater condenser is smaller than that of the seawater, even if a few light rays penetrate through the reflecting surface of the coating film, as long as the incident angle of the light rays is larger than or equal to the critical angle, the light rays are collected on the solar cell panel after being totally reflected on the surface of the light rays, so that the light rays are prevented from penetrating through the reflecting surface, the condensing efficiency of the inflatable condenser is increased, and the energy utilization rate of the whole composite device is further improved.
Has the advantages that:
(1) the invention has high energy utilization rate. The invention combines the solar power generation and the seawater desalination technology, so that the solar energy absorbed by the composite device system is fully and reasonably utilized, and the energy efficiency of the system is improved. The single utilization mode that solar energy can only generate electricity or generate heat in the traditional device is broken through, and combined utilization of heat and electricity is achieved. In addition, because the interior of the flexible inflatable condenser is air, when the incident angle of underwater light is larger than or equal to the critical angle, even a small amount of light penetrating through the reflecting film can be totally reflected, and then the light can be received by the solar panel. The flexible inflatable condenser further improves the energy utilization rate of the system by reflecting and totally reflecting incident light to collect and condense the light.
(2) The invention fully utilizes the wide ocean underwater light energy, provides endurance energy for underwater working devices, such as a submarine, a small submarine and the like, better completes underwater operation tasks and can solve the problem of water consumption of personnel in the underwater working devices.
(3) The invention can converge the low-energy current density solar beam into the high-energy current density focal spot, and the focal spot is arranged below the condenser, thereby realizing the reflection type forward focusing, so that the receiver can be arranged below the condenser, and the design and the installation of the whole system device are convenient. And when the system is in a non-working state, the flexible inflatable condenser can reduce the volume of the system through deflation, so that the whole system is simple and convenient and is easy to carry and store.
(4) The device has the advantages of compact structure, low manufacturing cost, stable operation, low maintenance cost and long service life, and can be applied in a large scale. All the components of the whole set of device comprise a flexible inflatable condenser, a solar panel, a ventilation water collector, a condenser, a conduit, a fresh water storage box and an air inlet and outlet valve. The regular arrangement of these components in one area makes the whole device very compact. Each part of the system is easy to process and standardize production, and the manufacturing cost is low. The whole system runs underwater, can resist severe weather such as sea strong wind and the like, and has the advantages of stable system running, low maintenance cost and long service life. The device can be arranged and combined under the sea surface to form a large-scale power generation and fresh water production system, thereby realizing low-cost and large-scale application of the undersea solar photovoltaic and seawater desalination.
(5) The invention provides a novel inflatable underwater condenser concept. According to underwater pressures at different depths, gas with proper mass is filled in the inflatable condenser, and under the action of the internal limiting diaphragm, the condenser forms a composite paraboloid and a reflecting film is plated on one side of the inner wall of the condenser, which is in contact with the gas. The underwater incident light is collected on the receiver through the operation modes of reflection and total reflection. The underwater flexible inflatable condenser provides a new direction for the future condenser design and also provides a new idea for the underwater solar energy utilization.

Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
FIG. 1 is a composite system of the present invention, which is inflatable underwater solar power generation and seawater desalination. The device mainly comprises: the solar energy air conditioner comprises a flexible inflatable condenser 1, an inflation valve 4, a solar panel 5, an aeration water collector 6, a condenser 9, a fresh water storage box 10, an air inlet and outlet valve 11 and a conduit 12, wherein the interior of the flexible inflatable condenser comprises a limiting diaphragm 2 with an air vent, and one side of the inner wall of the flexible inflatable condenser is coated with a reflecting film 3 and is in contact with air, the surface of the flexible inflatable condenser is provided with a thin through hole 7 and a channel 8. Wherein the flexible inflatable concentrator 1 is located at the uppermost end of the whole system. The limiting diaphragm 2 with the vent holes is positioned in the flexible inflatable condenser, the inside of the whole flexible condenser 1 is divided into a plurality of different small spaces, and the vent holes on the limiting diaphragm are communicated with the spaces. The reflecting film 3 is coated on the side of the inner surface of the flexible inflatable condenser, which is in contact with the air. The inflation valve 4 is located at a suitable position outside the upper portion of the flexible inflatable concentrator 1. The solar panel 5 is located at the position where the incident ray focal spot is located and the bottom of the solar panel is connected with the bottom of the flexible inflatable condenser 1. The condenser 9 is positioned above the solar cell panel 5, and the opening of the condenser is tightly connected with the top of the solar cell panel 5. The aeration collector 6 is located inside the condenser 9, and its outer edge is closely connected to the condenser 9, and its outlet is connected to the upper end of the conduit 12. The aeration collector 6 is distributed with fine through holes 7 through which steam can enter but underwater sundries cannot pass and a channel 8 for leading the fresh water formed in the condenser to a conduit 12. A fresh water storage tank 10 is located at the lowermost part of the system and is connected to the aeration trap 6 by a conduit 12. The upper part of the fresh water storage box 10 is connected with an air inlet and outlet valve 11 for inflation and deflation. The device can be designed into a three-dimensional rotating body structure and also can be designed into a groove type structure. The device can also be used in a large scale by forming more than two stages of systems in a series connection mode.
Fig. 2 is a light-gathering schematic diagram of the flexible inflatable light-gathering device. When the flexible inflatable concentrator 1 is placed under water, a plurality of small spaces divided by the limiting diaphragm 2 with the vent holes are filled through the inflation valve 4, and the whole concentrator forms a shape of a compound paraboloid. The underwater light 14 parallel to and close to the symmetry axis 16 reaches the compound paraboloid of the condenser 1 coated with the reflecting film 3 along the axial direction, and is collected on the solar cell panel 5 after being reflected by the paraboloid for the first time. And the light 13 parallel to and far from the symmetry axis 16 reaches the reflecting surface, then is reflected to fall on the reflecting surface on the other side of the symmetry axis 16, and then is finally converged on the solar cell panel 5 on the side after being reflected for two times or multiple times.
When the underwater incident light 17 forms a certain included angle with the symmetry axis 16, that is, the incident light enters the flexible inflatable condenser 1 obliquely, similar to the case of the parallel light 13 and 14, the incident light is reflected once or for many times by the composite paraboloid coated with the reflective film and finally collected on the solar cell panel 5.
When a small amount of incident light 15 penetrates through the reflective film, because the interior of the interlayer of the flexible inflatable condenser 1 is filled with gas, the refractive index of the flexible inflatable condenser is smaller than that of seawater, and the light with the incident angle larger than or equal to the critical angle of the flexible inflatable condenser cannot penetrate through the condenser 1 but is collected on the solar panel 5 after the inner surface of the flexible inflatable condenser is totally reflected.
The flexible inflatable condenser 1 utilizes the modes of light reflection, multiple reflection, total reflection and the like, so that incident light can be collected on the solar cell panel 5, and the utilization rate of the system to solar energy is improved.
As shown in fig. 3, the operation principle of the device is illustrated as follows: when the inflatable underwater solar power generation and seawater desalination combined device is placed under seawater, the gas can fill a plurality of small spaces divided by the limiting membrane 2 with the vent holes through the inflation valve 4, so that the underwater inflatable concentrator 1 has a proper compound parabolic shape. The majority of incident light 17 entering underwater is converged on the solar panel 5 after being reflected once or for multiple times by the reflecting film 3 coated on the inner surface of the condenser 1; a small amount of light rays which penetrate through the reflective film and have an incident angle larger than the critical angle are totally reflected on the surface of the condenser on the film coating side and then are also converged on the solar cell panel 5. The solar cell panel 5 receives the collected solar power and outputs the power to the outside, and the waste heat generated by the solar cell panel 5 is conducted to the seawater in the middle of the cell panel system through the back surface of the solar cell panel. The air quantity in the condenser 9 is controlled by the air inlet and outlet valve 11, so that the free liquid level 19 below the condenser 9 just submerges the upper end of the solar cell panel and does not exceed the lowest point of the thin through hole 7 on the ventilation water collector 6. The seawater in the middle of the panel system is heated to generate high temperature steam at the free liquid level 19. High-temperature steam enters a condenser 9 through a thin through hole 7 on the ventilation water collector 6; because the seawater temperature of the outer wall of the condenser 9 is low, high-temperature steam is condensed on the inner wall of the condenser to form fresh water drops 18; the fresh water droplets 18 will flow by gravity through the channel 8 in the air trap 6 to the conduit 12 and then converge along the conduit to the fresh water storage tank 10. When the fresh water collected by the fresh water storage box 10 is continuously increased, the original air in the fresh water storage box 10 is extruded into the condenser 9, when the extruded air is too much, the free liquid level 19 is reduced due to the too large gas pressure in the condenser 9, and finally the liquid cannot submerge the solar cell panel 5, so that the heat dissipation of the solar cell panel and the yield of the fresh water are influenced. When this occurs, the inlet and outlet valves 11 need to be opened to vent excess gas from the fresh water storage tank to reduce the gas pressure in the condenser and thereby maintain the free liquid level 19 at a suitable level.
In one embodiment, as shown in fig. 4, the inclined vented limiting membrane 2 in the flexible inflatable underwater concentrator 1 is replaced by a vented horizontal limiting membrane 20.
In one embodiment, as shown in figure 5, a thermosiphon condensing coil 21 is added to the condenser 9. Cold seawater enters from an inlet 23 of the condensing coil 21, part of high-temperature steam in the condenser 9 is condensed into fresh water on the inner wall surface, and the other part of high-temperature steam contacts the thermosiphon condensing coil 21 to release heat and is condensed into fresh water. The density of the seawater in the condensing coil becomes lower, and the other end of the condensing pipe is wrapped by the heat-insulating layer 22, so that the temperature in the condensing pipe is still lower and the density is high. Because the density difference exists in the seawater inside the thermosiphon condensing coil, the seawater flows from the place with low density to the place with high density, so the seawater forms natural convection in the condensing coil 21 and flows from the inlet 23 to the outlet 24, and further the effect of condensing the steam in the condenser is realized.
In one embodiment, as shown in fig. 6, the flexible inflatable underwater concentrator system eliminates the seawater desalination system and only retains the solar panel for power generation, so that the whole system is more compact and concise.
In one embodiment, as shown in fig. 7, the flexible, inflatable concentrator is a trough-type system.
In one embodiment, as shown in fig. 8, the rotating and trough concentrator systems, respectively, are scaled for use in series.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
