Description

POTABILIZATION SYSTEM FOR WATER FROM THE SEA OR OTHER HARD OR DIRTY WATER, WITH THE HELP OF SOLAR ENERGY.

FIELD OF THE INVENTION

This disclosure deals with a purification system through purification and distillation processes of water from the sea or other hard or dirty water, with the help of renewable energy sources, mainly solar.

BACKGROUND OF THE INVENTION

The water situation is critical, the biggest problem is that people are dying due to lack of water. The problems of this are diverse, mainly due to the lack of rain for prolonged periods. In addition, climate change and forest fires deteriorate the soil and the ecosystem, causing evaporation of lakes and rivers. This also affects livestock, but fundamentally agriculture requires huge amounts of water to produce, the income of local farmers will be strongly affected.

The most vulnerable populations are affected by famine and deaths from dehydration, forced to emigrate or go in search of cities with a drinking water system. On the other hand, the lack of infrastructure and the fact that existing water sources are contaminated are one of the reasons for the transmission of diseases and the need to import water from other places.

There are many organizations that have sought ways to solve the water problem in the world, among which civil donations and the implementation of policies that are not feasible in some communities stand out.

It is for the above that our project was born, whose purpose is to provide a water purification system for the communities that most require this precious and scarce resource, through the implementation of a water purification system. DESCRIPTION OF THE PREVIOUS TECHNIQUE:

The document ES1019211 (II), deals with a drinking water transformer-distiller specially conceived and designed to obtain water suitable for human consumption in places and geographical areas lacking said liquid element, starting from water in poor hygienic conditions, contaminated and saline. , in short, not drinkable due to its chemical and bacteriological characteristics that discourage and prohibit its use and utilization. In essence, it comprises two fundamental pieces consisting of a lower container, a wastewater container and in poor hygienic conditions, with a low overall cylindrical configuration, opaque and black on the inside, and an upper dome or vault made of transparent material that advantageously allows the passage of sunlight and has, internally and peripherally, a collector for collecting distilled water, positioned with a slope of up to 20% so that the condensed water runs towards the point of exit to the outside without the slightest impediment.

In LIS2015353379 (A1), a panel-interfaced photovoltaic hybrid distillation system is provided with and without a hydrophobic microporous membrane distillation process that is capable of utilizing solar waste heat to perform liquid distillation while cogenerating solar electricity. Solar waste heat co-generated in a photovoltaic panel is effectively utilized by the “in situ” distillation liquid as an immediate heat sink in thermal contact with the photovoltaic panel, thus providing beneficial cooling of the photovoltaic panel and co-manufacturing of products. of distillation while generating electricity with significant improvement in total process solar energy utilization efficiency. Its enabled beneficial utilization of waste heat can provide a number of distillation-related products such as: fresh water, sea salts, distilled water, distilled ethanol, hot water, hot steam, brine/salt products, and brine photobiological cultures for production. of advanced biofuels and bioproducts, in addition to solar energy. Document US8186100 proposes a solar energy type photovoltaic greenhouse, which includes a main greenhouse frame structure with multiple vertical walls and a roof on them, to enclose a greenhouse space, and at least one film solar cell module slim ceiling mounted. The thin film solar cell module is useful for converting solar energy within a preselected band of sunlight into electricity, and at the same time, the light that is not absorbed by the thin film solar cell module freely passes through. of the thin-film solar cell module and enters the interior space of the greenhouse. Sunlight that freely passes through the thin-film solar cell module includes enough light that plants or crops can use for photosynthesis.

The document W02014131027, has a greenhouse that according to some embodiments includes a wraparound structure and at least a part of the wraparound structure is at least 10% transparent to sunlight in at least a part of the range of 400 - 700 nm of wavelengths of light. The portion of the shell structure that is at least 10% transparent to sunlight includes a transparent organic photovoltaic cell. The greenhouse panel according to one embodiment of the invention includes a transparent organic photovoltaic cell that is at least 10% transparent to sunlight in at least part of the 400-700nm range of wavelengths of light and it is sensitive to light in a range of wavelengths outside the 400-700nm range of wavelengths.

In addition, it is known that within the state of the art of the existing solutions to attack the lack of drinking water is the use of aquifers as a water reservoir, reforestation of forests, search technologies for underground water tables, programs for saving water resources. worldwide, rainwater collectors, water sanitation and desalination processes.

An important aspect to point out, although it is obvious, is that not all water treatment processes are designed the same, since the design will depend in a very important way on the characteristics of the available water. It is not the same to design a water treatment plant for the Persian Gulf than for the Pacific Ocean, the Mediterranean Sea or the Atlantic Ocean. But even more, located in the same sea, depending on the circumstances of the micro zone, the design can be radically different.

Potabilization technologies and specifically for desalination can be separated into those that extract water and those that extract salts. Electrodialysis is an example of technology that extracts salt from water. Water extraction technologies may or may not act through phase change. Among the technologies that do not take advantage of the phase change are those of filtering, such as reverse osmosis.

In phase change technologies through evaporation are found. Multi Effect Distillation (MED), Thermal Vapor Compression (TVC), Mechanical Vapor Compression (MVC), Multistage Flash Evaporation (MSF), solar stills and Distillation Membranes (MD).

Regarding the rest of the existing technologies, we can mention wind desalination plants, vapor compression plants, reverse osmosis plants. The current boom lies in reverse osmosis plants, these plants can be self-sufficient when photovoltaic panels are added, the use of this technology is known as RO+PV plants.

However, in the prior art there is not a water distillation system that integrates all the technologies that comprise the present innovation, that is to say as a whole it presents a combination of elements that appears as novel with respect to the prior art, especially the use of transparent photovoltaic panels as means of capturing solar energy, which allow maximizing the light resource by taking advantage of the entire exterior surface of a closed plant for capturing light energy as a capturing source.

Solve the general problem of water scarcity, an option to obtain it. Furthermore, the model for obtaining water is made in such a way that its costs be as low as possible, so that they can be carried out anywhere in the world.

In addition, another purpose of the invention is to contribute to the environment, so it is also designed so that its impact is minimal in the territory where it will be installed, as well as intended to be sustainable in the long term, helping to improve the quality of life of the people.

The system would also help the non-exploitation of non-renewable resources, such as the depletion of groundwater, improper use of these or other sources that may be depleted in the future.

Finally, obtaining it, for example, through the misalignment of water would allow a disruptive appeasement of major events that have a negative impact on countries (theft of water, creation of reservoirs and dams, diversion of water, etc.).

The users are different and vahados among which there may be from livestock groups, government, production, etc. The main ones are production companies with scarce water resources, mining companies and the like at a global level, they usually resort to the use of enough water for their projects, that is why this method provides them with a solution that does not affect their work or the environment causing scarcity. to the people.

The livestock and rural food industries such as large plantations, where water is usually a scarce commodity or rather, obtaining it is not through an act of high impact on the world and on the population that needs it, such as destroy ecosystems or others.

Governmental for distribution to localities with water scarcity and that are in a critical situation due to the lack of it. Finally, how it would work would preferably be in coastal places, not inhabitable within a radius of "x" kilometers (depending on the size of the plant), providing water through pipelines through nearby sectors, or moving to more distant places. When and where, at all times as long as the situation and place are suitable for the installation of the plant. Because it is a way of taking advantage of water, using non-exhaustible resources in the very long term (sea water and solar energy), for what, it can be defined as the purpose of obtaining benefits both economically and in the care of the world in general. .

DESCRIPTION OF THE INVENTION

The system has various processes, for example, in a non-limiting modality with the invention, which was designed to be installed on the sea coast, it has a water collection system which includes filters to separate the largest elements contained in water as soil, stones, minerals and mud. Then the water is filtered through membrane systems until it reaches a pond where biological and chemical processes are applied to separate other smaller agents present in the water.

From this point a water extraction system is installed on the surface that allows the passage of water to a water tank that allows the water to be at a temperature higher than the ambient temperature, and at this point two valves are installed, the first for to be able to extract non-potable water directly from the tank, and the second is an automatic valve that allows a pool to be maintained at the optimum water level. This pool is formed with polymers that allow the water to absorb heat energy from various sources, mainly solar through collectors, panels and a glass structure that completely covers the pool.

This structure has the function of allowing and increasing the entry of solar rays into its interior, as well as being the fundamental piece to be able to capture the water vapor and guide it to the final collector where the distilled water remains. The invention that seeks to implement a seawater misalignment system with the help of the sun, for which pools are designed no more than 10 cm deep by one meter long and wide, which will be installed in populated coastal areas, the The idea of the size and depth of these pools is that they can carry out the purification process by taking advantage of the amount of UV rays.

These pools, made with black hydrophobic polymers with usable absorption and thermal conduction properties, will capture even more UV radiation and the sun's heat to help increase the temperature of the water to its boiling point.

In preferred embodiments and only by way of example, in order for this task to be faster and more efficient, the invention has a closed structure, which can have the shape of a dome or in the shape of a truncated pyramid, with multiple faces, either square, rectangular , hexagonal, pentagonal, etc., which allows amplifying the sunlight that will cover and insulate the place, it will act in the form of a magnifying glass, concentrating the heat optimally in the entire area covered with water.

In the same modality for capturing seawater, the invention considers an underground pipeline for capturing seawater by waves, which will advance by gravity through different layers of physical filtering as well as easy-to-maintain membranes, in order to reach the aquifer located at a depth not exceeding 10 meters below sea level. In the event that the waves are not sufficient, it will be supported by pumps powered by a renewable energy source.

Anaerobic bacteria and other chemical-biological processes necessary to clean and purify the water are also used for water sanitation.

The system has a compact pressure water extractor, driven by a pump powered by renewable energy, storing the still salty water in a container that will have a siphon system to maintain the water level. Then the water finally reaches the dome described above, which consists of two great virtues, one of these is the extraction of purified water directly from the dome, while the remaining water will filter naturally, forming an aquifer, which will allow the water to flow through processes such as surface tension and earth pressure towards layers of land located closer to the surface. This has a great impact on the place, because over time these places can be used again for cultivation and reforestation.

The means to condense the water can be through a central column or through the edges that form the photovoltaic panels.

Alternatively, it can incorporate storage batteries, in order to, and if required, have energy to self-power the device and maintain a continuous production of distillate.

In another modality, a compact and/or portable system for purifying water from the sea or other hard or dirty water is defined, using solar energy, for areas with scarce water resources, with low environmental impact, and which performs the distillation of the water in a autonomous, which avoids the exploitation of non-renewable resources, such as the depletion of groundwater or other sources, which includes: A structure to contain liquids, preferably thermally insulated and closed at the top by a dome or cover, which is manufactured of transparent photovoltaic panels, completely covering the dome or roof or at least most of it, as means for capturing solar energy, which produce the greenhouse effect inside the structure and also generate electricity for the system and also generate energy electric for external use; a water accumulation pond that receives water from a source; a water storage pool that receives water from the accumulation pond, this pool is under the dome made of transparent photovoltaic panels; and evaporated water condensation means that allow the purified water to be extracted directly from inside the dome.

In this portable or compact mode, the water storage pool is also made of black hydrophobic polymers with properties of usable thermal absorption and conduction, which further capture UV radiation, making it easier for the water temperature to reach its boiling point.

The portable or compact modality of the invention also has a closed structure, which can be dome-shaped or in the form of a truncated pyramid, with multiple faces, whether square, rectangular, hexagonal, pentagonal, etc., which allows the light to be amplified. solar panel that will cover and insulate the place, it will act in the form of a magnifying glass, concentrating heat optimally throughout the area covered with water, with transparent and non-transparent photovoltaic panels.

The means to condense the water in the portable or compact mode can be through a central column or through the edges that form the photovoltaic panels. Storage batteries are also incorporated, in order to, and if required, have energy to self-power the device and maintain continuous production of distillate.

In other of its modalities, a water purification and desalination process is defined that includes providing a structure to contain liquids, preferably thermally insulated and closed at the top by a dome or cover, which is made especially of transparent photovoltaic panels such as means for capturing solar energy, completely covering the dome or roof or at least most of it, which allow the greenhouse effect to be produced inside the structure and also generate the electrical energy necessary for the process and generate electrical energy for use external, maximizing the light resource by taking advantage of the entire exterior surface of the structure as a capturing source.

In addition, a non-drinking water collection and filtering stage is defined, where a primary water filtering stage is carried out, which includes a set of filters to separate the largest elements contained in the water, such as earth, stones, minerals. and mud. In addition, a secondary filtering stage of the water is carried out, which includes a set of membranes, where biological and chemical processes are applied to separate other smaller agents present in the water.

In addition, a primary water storage stage is carried out using a well as storage;

In addition, a secondary water storage stage is carried out using a pond as storage.

In the water distillation stage, the dome or cover made of transparent photovoltaic panels is used, covering a pool with previously treated water, covering and insulating the pool, concentrating the heat throughout the area covered with water.

In an evaporation stage, the water stored in the storage pool, and due to light amplification, the temperature of the water is increased to a temperature higher than the ambient temperature, which allows the water to evaporate.

Finally, a condensation stage is defined, where the purified water is extracted directly from the dome or vault and the rest of the distilled water generated is used for cultivation and reforestation, or for the generation of electrical or thermal energy.

The virtue of the invention is the use of renewable energies that do not generate more damage to the planet, but take advantage of the natural processes that it offers us for the generation of drinking water. The set of processes and instruments used can categorize this as a renewable and autonomous potabilization system.

This innovation proposes the definition of a purification system through processes of purification and desalination of water from the sea or purification of other hard or dirty water, with the help of energy sources. specifically solar renewable through transparent photovoltaic panels in the distillation stage, maximizing the surface of the system structure, which also allow the generation of electrical energy.
