Description

{DISTILLING APPARATUS FOR SALT WATER}

The technique of the present invention relates to a technique for obtaining distilled water and concentrated water using salt water such as seawater and natural atmosphere.

      Generally, conventionally, the above-mentioned brine is distilled, and salt is formed from ancient times, and heat is generated by burning solar heat or firewood to evaporate water from salt water to obtain salt, and water evaporating from the ocean and the land is cooled It has been used to collect rainwater that has been condensed and dripped. In modern times, the osmotic mechanism has been interpreted and semi-permeable membrane manufacturing technology has been developed, and the reverse osmosis method is typically used for the desalination of salt water such as seawater.

     The method of acquiring salinity by the ancient torsion has difficulties in using land of a large beach, storing salt water according to the weather and repeating the sun exposure, and not obtaining the distilled water directly.

     In addition, the method of obtaining water by heating the brine using fuel requires the evaporation heat of about 540 Cal per 1 cc of water and the cooling heat of the same amount again so that there is a physical limitation of the fuel and the heat dissipating facility to obtain a large amount of distilled water, Or the waste heat of the marine engine,

In modern, reverse osmosis technology, in order to separate water, seawater requires a high pressure of at least about 24 atmospheres and an atmospheric pressure of about 50 atmospheric pressure, depending on the salinity of about 3% In comparison with the conventional heating method, about one sixth of the energy level is required. This method also requires a lot of energy to acquire a large amount of water.

It is an object of the present invention to provide an apparatus for obtaining a large amount of distilled water and concentrated water as a small size apparatus which can be applied industrially in a conventional salt water distillation method without application of heat energy and further, The present invention is a solution of the present invention

A first water surface (41) for generating vaporization cooling heat by containing salt water in the outside of the closed space and contacting the salt water with surrounding air, (42) for transferring the vaporized cooling heat generated at the first water surface by contacting the air inside the closed space by surrounding air, and a brine containing the brine inside the closed space, A second water surface 51 for generating vaporized cooling heat by being in contact with the air of the second water surface, and a second front surface 52 for transferring vaporized cooling heat generated from the second water surface to the outside air outside the closed space ) Is a mechanical means,

       The conventional atmosphere 60 is simultaneously brought into contact with the first water surface 41 and the second previous water surface 52 which are outside the closed space and the first water surface 41 and the second water surface 51 The water is supplied through the supply water 10.

       Using the above means,

       The distilled water collected in the first complete drawing 42 inside the closed space and the condensed water 44 dripped at the water surface 41 and 51 is collected as latent heat release in the air, And the supply water 10 are vaporized (43, 53) and the remaining concentrated water 80 is obtained in a large amount.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS For a detailed description of the practice of the present invention, the construction and operation will be described by way of example with reference to the drawings.

  Features of the main components used in the present invention will be described first.

  The supply water (10) is representative salt water on the earth, and is utilized for the convenience of understanding because it is highly utilized. It is not intended to limit general salt, but it can be applied to all liquids which can be separated by distillable solvent and solute Of course.

  The feed water 10 is generally constituted as a composite salt such as sodium chloride (NaCl), magnesium chloride (MgCl2), calcium chloride (CaCl2), etc., and evaporates water vapor in an atmosphere below normal saturated humidity, There is a characteristic of generating heat.

    The closed space 30 is a concept of a relative closed space with respect to the natural atmosphere 60. It has a three-dimensional boundary surface and a volume, blocks fluid movement inside and outside, can create an artificial passage to move the fluid, If the movement of the fluid between the inside and the outside is interrupted even if a part of the interface is replaced, it is regarded as one closed space including the other components of the name, and the heat transfer is blocked according to the thermal conductivity of the constituent material of the interface. The relative humidity inside the closed space rises continuously to the end according to the concentration of the disturbing salinity contained in the saline water, In the case of seawater, a quasi-saturation condition with a relative humidity of 99% or more at room temperature, and a minute cooling inside the confined space , The main characteristic of the present invention is that the water vapor is easily supersaturated and condensed.

    The water surface 41, 51 includes brine, which is in contact with the surrounding air and is vaporized according to the relative humidity. The amount of vaporization generated is proportional to the contact area, but the vaporization is called latent heat release, As a result, vaporization cooling occurs and the relative humidity of the ambient atmosphere rises, and the vaporization rate becomes slow again. In order to accelerate the vaporization, the surrounding air is forcedly blown and forced to exchange the air, , Which is the main means by which the device of the present invention operates itself

    The previous drawings 42 and 52 transmit the heat inside the conductor to the surrounding air and are made to block the fluid flowing inside the conductor from flowing out from the conductive surface. Usually, when the heat conduction distance is short As shown in FIG. 1, the back surface of the water surface 41, 51 is used without flowing a fluid inside the conductor, and a single-piece ceramic or metal material having better heat conductivity than air or water is used. The heat conduction medium is circulated through a natural convection or a duct to receive heat and radiate heat or absorb heat according to the temperature difference in the surrounding air through the surface of the front surface. At this time, the surface of the heat transfer surface in contact with the air is thin, has a large area, and is characterized in that effective heat transfer is performed when the ambient air is exchanged by convection or blowing air.

     FIG. 1 shows components for explaining the technical principle of the present invention. The operation of acquiring the distilled water 70 and the concentrated water 80 from the feed water 10 will be described.

     The seawater as the supply water 10 is distributed to the first water surface 41 and the second water surface 51 in a first small amount and the first water surface 41 is disposed outside the closed space And the first atmospheric flow 61 which is a part of the normal atmosphere 60 is brought into contact with the first atmosphere vapor to generate vaporized cooling heat due to evaporation of the first water vapor 43.

     The second water surface 52 is arranged so as to be opposite to the first water surface 41. The second water surface 52 is disposed inside the closed space so that the second water surface 53 is in contact with the inside airflow 63 inside the closed space, , The relative humidity of the internal space is raised and leveled by the internal airflow 63 with the lapse of time, so that the inside of the sealed space reaches the quasi-saturated state.

    At this time, a first entire drawing 42 in a heat exchange relationship with the first water surface 41 is disposed inside the closed space to make contact with the air in the quasi-saturation humidity state, and the second water surface 51, The second entire drawing 52 in the heat exchange relationship with the atmosphere is placed outside the closed space to contact the normal atmosphere 62 to supplement the vaporization cooling heat generated on the second water surface 51,

    As the cooling heat is conducted around the first whole view, the steam of the air in the quasi-saturated state in the closed space is transited to the supersaturated state so as to condense with water droplets on the first previous drawing (42) The temperature is slightly lowered to generate the internal airflow 63 in the closed space to perform heat exchange with water vapor,

    The second supplemental water is supplied to the second water surface 51 from the second atmospheric flow 62 which is a part of the normal atmosphere 60, Not only the water vapor 53 is released but also the air temperature around the second water surface 51 is slightly raised so that the internal airflow 63 in the closed space is accelerated and the heat exchange with the water vapor is further activated.

    In addition, the initial small amount of the feed water (10), when it is supplied at a small amount, dries or forms crystals on each water surface and obstructs heat flow in the closed space when the feed amount is large. Control and supply,

    In order to prevent the mixing of the condensed water passing through the second water surface 51 and the produced distilled condensate water 44 in the closed space 30, ) Is installed and operated.

     As a result, the phenomenon in which the vaporization cooling heat generated in the first water surface 41 is supplemented by endothermic heat 60 from the same atmosphere 60 in the second previous drawing 52 is maintained The water vapor 53 generated by evaporation of the supply water 10 is converted into the condensation water 44 in the closed space to collect the condensation water to obtain the distilled water 70, The first water vapor 43 and the second water vapor 53 are vaporized in the first water surface 41 and the second water surface 51 so that the concentrated water 80 collected continuously can be continuously obtained.

     At this time, in the case where the temperature of (42) in the first entire drawing is an image, a separate energy supply for distillation is provided except for the inflow and distribution 20 of the feed water 10 and the inflow and distribution of air 60 And is characterized in that distilled water and concentrated water are obtained as latent heat release and endothermic heat in the atmosphere 60. This shows a distinctive structure and effect different from the conventional technology,

     In addition, as the gap between the first front view 42 and the second water surface 51 in the closed space 30 is narrower, and as the temperature difference due to vaporization cooling is larger, The production rate of distilled water and concentrated water is also fast,

     This can be achieved by reducing the size of the device and integrating it in the form of a shallow lid. It can be mass-produced by forced circulation through a fan inside and outside the enclosed vessel, There is a fast industrial utility.

     The technical principle of the present invention described above is that, in actual operation, depending on the weather environment, e.g.

     In the rainy season, the relative humidity of the atmosphere is close to the saturation state, and the rate of atmospheric emission of salt water is remarkably reduced,

     In winter, the temperature of the atmosphere may be below zero, which is the freezing point. At this time, the condensation is frozen,

     A preferred embodiment of a real system device for solving all problems in commercial use will be described with reference to FIG.

     The offshore structure 200 includes a system for commissioning the apparatus of the present invention and constitutes and operates the system as a part-by-one interworking system.

     The atmospheric derivative 211 is a means for introducing the atmosphere outside the structure into the inside of the structure. At first, air is introduced into the structure 200 by the natural wind force, and in case of the weak wind, Respectively.

     The solar energy 212 is a means for obtaining the necessary power and heat during operation of the system including the present invention and obtains the starting power at the time of the initial operation and after the commencement of the operation, ) Is heated to selectively store a highly corrosive salt such as calcium chloride or magnesium chloride and store it in the dehumidifying salt tank 213.

      The dehumidifying salt tank 213 is connected to the atmospheric air 211 and the distillation unit 214 only when the relative humidity in the atmosphere reaches a quasi saturated state, Is an emergency operation means for allowing the distillation apparatus to operate normally by absorbing water vapor from the atmosphere.

      1, the distillation apparatus 214 of the present invention automatically controls the inflow amount of seawater by adding a sensor and a pump device so that the inside of the distillation apparatus 214 is not dried or overcrowded during commercial use, and the produced distilled water is supplied to the water tank 219 ). Particularly, it is preferable to operate the heating and heating apparatus continuously so that the internal water vapor will freeze in the winter and the apparatus will not deform and fail.

      The saline solution power source 215 generates and uses continuous power required for the operation of the apparatus of the present invention by supplying the concentrated water obtained as the result of the present invention to the decontamination chamber 217 and recombining the concentrated water with the filtered seawater 216.

      The decontamination room 217 stores the concentrated water produced from the constant distillation unit 214 and supplies the concentrated water to the salt water source power supply unit 215 at a small amount and a high pressure in order to convert it into electric power, By conducting heat exchange with the atmosphere, highly concentrated brine is leached out into crystals and discharged as solid.

     At this time, the produced crystal salt and concentrated water contain all the components of seawater such as various trace elements and are classified into various industrial applications such as edible and cosmetics, agricultural use,

      If the seawater 216 contains radioactive elements that are difficult to handle immediately, or industrial wastes or washing water resulting from incineration, the treatment can be simplified by maximizing the concentration and drying of a large amount of waste without additional energy, There is an industrial effect.

     The water pipe (218) is a conduit means for thoroughly sending distilled water collected in the water tank (219) to the consumer on the land.

     In order to facilitate understanding of the principles, one closed space 30 device is arranged laterally in a square shape and the flow of each fluid is schematically illustrated in parallel,

     By using the technical principle of the present invention, it is possible to use the apparatus of the present invention in which a plurality of layers are arranged successively, longitudinally or laterally, and the flow of each fluid (atmospheric, seawater, distilled water) is serial and parallel, It is to be understood that the present invention is not limited to the application of the known technology, such as adding an activation fan inside or outside the closed space.
