    DESCRIPTION
    PLANT AND METHOD OF PURIFICATION OF FLUIDS BY DISTILLATION
    Object of the invention
    The object of the present invention is a distillation fluid purification system that separates the solids diluted in the fluid by accelerating the fluid.
    State of the art
    To date the most common methods of water purification are by mechanical means and filters, as for example described in P201130239. In this document, by way of example, it is indicated that a water purification device and procedure allows the filtration, purification and distillation of water by a single device, using only solar energy (UV radiation and IR radiation), also emphasizing its character portable and ergonomic, which gives it the ability to be used in any place and / or situation. Said device stands out mainly for comprising a micropore bag containing a filtering material, such as activated carbon, ultrafine resin or the like, for the filtering of dirty water, eliminating any microorganism, smell and color of said dirty water for obtaining water. filtered, as well as a container that presents on its surface an area provided with thermochromic paint adapted to indicate to the user the moment in which the water contained is already purified, by a color change of said thermochromic paint after the water reaches a certain temperature during sun exposure.
    On the other hand, methods that involve the use of membranes and vapor condensation are also used, as in ES 2 388 882 which describes a method for the purification of a liquid by membrane distillation, which comprises passing a stream of retained fraction vaporizing liquid heated through a retained fraction channel along a hydrophobic porous membrane, whereby the vapor of the liquid flows through the pores of the membrane to the other side of said membrane, and condense said vapor into the another face of said membrane to produce a distillate stream in a distillation channel, whose distillate is created by passing the heat of condensation (latent heat) to a condenser surface, said condenser surface forming a non-porous separation between a feed stream of the liquid to be purified and said distillate stream, whose feed stream is passed through

    a feed channel in countercurrent with the fractional current retained and whose power channel is hydraulically connected downstream with the fractional current retained, in which power channel a spacer material is disposed, by which at least one part of the latent heat is transferred through the surface of the condenser to the feed stream, and by which a positive pressure difference of the liquid is applied between the stream of the retained fraction and the feed stream at the corresponding points of the channel of the retained fraction and the feed channel, at least, on a portion of each of the retained fraction channel and the feed channel.
    Description of the invention
    As indicated, the object of the present invention is a method and a distillation fluid purification plant that takes advantage of the fact that a fluid with solid components in solution at high temperature and high pressure is passed through a nozzle until it reaches a speed close to the speed of sound.
    The fluid, by passing through the nozzle lowers its pressure, reaching a state of depression that causes it to reach its vapor pressure at that temperature, being at this moment where the solid components of the fluid are separated in a gaseous state. Thus the solid components separated from the clean steam are obtained, which continues its way to the condensation phase, where it is already purified.
    Therefore, the present invention uses a distillation system to separate the diluted solids by acceleration at fluid speeds close to that of sound. This implies that the fluid in the liquid state, for example seawater, is purified in a totally physical way, without chemical treatments of any kind and without a large consumption of energy that, in addition, can be obtained thanks to clean energies.
    Throughout the description and the claims the word "comprises" and its variants are not intended to exclude other technical characteristics, additives, components or steps. For those skilled in the art, other objects, advantages and features of the invention will be derived partly from the description and partly from the practice of the invention. The following examples and drawings are provided by way of illustration, and are not intended to restrict the present invention. In addition, the present invention covers all possible

    combinations of particular and preferred embodiments indicated herein.
    Brief description of the figures
    A series of drawings that help to better understand the invention and that expressly relate to an embodiment of said invention that is presented as a non-limiting example thereof is described very briefly below.
    FIG. 1 shows a block diagram of a purification plant according to 10 with a practical embodiment of the invention.
    Statement of a detailed embodiment of the invention
    In a preferred embodiment of the invention it is proposed to obtain drinking water from
    15 of water not usable for human consumption. Therefore, a cleaning cycle is proposed based on the separation of diluted solids through the kinetics of the biphasic liquid-vapor mixture. This will take into account that:
    i. The temperature of the liquid must be raised to its boiling point under 20 extreme conditions of pressure and temperature.
    to. Obtaining the necessary energy from any ecological system present in the surrounding nature of the place where the purification plant is placed, that is, wind, solar or any other renewable energy and / or low associated cost; Y
    25 b. Performing the thermal exchange with a primary thermal fluid configured as heat transfer to the system cycle.
    ii. Raising the speed of the biphasic vapor-liquid mixture at speeds of the order of 450 m / s (Mach 0.85) that produce temperature variations of up to 60 ° C for a few milliseconds, breaking up the pure water of the
    30 salts present instantly.
    The result of the development results in a process that obtains at the exit two products: a) Clean water of high purity. b) Solid state wastes (for example, in the case of seawater, common salt).

    An embodiment of the purification plant object of the present invention is shown in Figure 1. Thus, from a water tank not usable for human consumption (1) the fluid passes through a first filter (2) of impurities and, by means of a pump (3), the pressure and the temperature of the fluid are raised to a temperature not exceeding at 253 ° C. The fluid passes
    5 subsequently to a heating zone (4) where the fluid is heated by a heat transfer fluid, which is at a temperature not exceeding 275 ° C.
    The heated fluid subsequently passes to a convergent-divergent nozzle (5) that accelerates the fluid at speeds close to the fluid velocity (preferably of the order
    10 of 450 m / s), performing a compression - adiabatic expansion of the liquid-vapor two-phase system.
    Finally, in each of the solids deposits (6), the solids precipitate at the bottom, while the purified water is condensed in a condenser (7) to be stored in
    15 a reservoir of purified fluid (8).
    In the practical embodiment shown in Figure 1, various separation stages (5,6,7) are arranged which are fed back with different thermal gradients (difference between the inlet and outlet temperature of the fluid).
    20 Numerically, in the plant shown in Figure 1 for a mass flow rate of 30 l / min and a thermal gradient between the inlet and outlet of 32.3 ° C with a fluid density of 0.78 kg / dm3 as well as a Specific heat of 2510 J / Kg gives 3 l / min of purified water and 105 gr of salt / min for seawater, with a thermal balance of 13.35
    25 KW / liter of water obtained.
