    FOG DISSIPATION INSTALLATION
    DESCRIPTION
    5 OBJECT OF THE INVENTION
    The present invention is part of the technical field of safety systems for fog protection.
    10 More specifically, an installation of mist dissipation by diffusion of hygroscopic substances is described.
    BACKGROUND OF THE INVENTION
    15 The World Meteorological Organization defines atmospheric fog as the suspension
    in the air of small drops of water, generally of microscopic size, which can lead to the reduction of horizontal visibility on the earth's surface below 1,000 m.
    20 There are different ways of classifying mists, such as according to their formation mechanism. In accordance with this criterion, the fogs can be classified into radiation fog, advent fog, evaporation and mixing fog, or frontal fog and elevation fog.
    25 Another possible classification is based on temperature. According to this criterion, the mists are classified into three types: super cold fog, cold fog and hot fog.
    In a first approximation, the visibility of the fog is regulated by the following expression:
    image 1
    Where K is a constant, r is the average radius of the drops of water and W is the humidity of the drops of fog in the air.
    5
    Likewise, a mathematical expression is known that relates the visibility of the fog with the concentration of water drops and the humidity of the drops of fog in the air:
    V = ----——
    (W * Nd) Ak2
    Where Nd is the concentration of water drops, W is the humidity of the drops of fog in the air and k1 and k2 are constant.
    Based on these formulas, in order to improve visibility in foggy areas, it is necessary to act by increasing the average radius of the drops, or by decreasing the amount of water in fog drops, or by modifying both factors at the same time.
    DESCRIPTION OF THE INVENTION
    The mist diffusion installation of the present invention is designed to spray, through a plurality of diffusers, an aqueous solution comprising at least one hygroscopic substance.
    When spraying the aqueous solution, the drops of said aqueous solution come into contact with the drops of water that form the fog and by condensation and coalescence they are grouped together, increasing their size. In this way, the drops that greatly increase their size end up precipitating, in the form of rain or snow, thus eliminating the fog and increasing visibility.
    Preferably, the hygroscopic substance of the aqueous solution that is diffused is selected from urea, ammonium nitrate, calcium chloride, sodium chloride or any combination of the foregoing.
    The mist diffusion installation comprises at least one support structure and a spray equipment. The spray equipment comprises a water supply, a hygroscopic substance storage tank and a dispenser that regulates the amount of said substance that is mixed with water to create the aqueous solution that is sprayed.
    Also, the spray equipment comprises at least one pressure pump to drive the aqueous solution through conduction tubes that are connected to a plurality of diffusers.
    5
    Both the diffusers and the conduit tubes are supported or connected to the fixed support structure that can have different configurations.
    In an example of realization, the installation of fog dissipation is installed in sections 10 of roads, such as highways, in which there is usually fog that decreases visibility, affecting driving. In these cases the support structure covers at least the stretch of road along which you want to blur the fog. Also, in this embodiment, the support structure has a galibo and a large enough opening to allow vehicles to pass through it.
    fifteen
    Likewise, the mist diffusion installation comprises a control unit that allows, when detecting the presence of fog in the area where the structure is installed, to activate the spray equipment.
    The installation may comprise a visibility and climate sensor that is connected to the control unit and that when detecting the presence of fog sends a signal to said control unit that automatically connects the spraying equipment. At that time, the water supply, the hygroscopic substances dispenser are connected to obtain the aqueous solution and the pressure pump is connected to send said aqueous solution, through the conduit pipes, to the diffusers through which it is sprayed. .
    Spraying is done with drops of a certain size depending on the fog conditions that have been detected. The size of the drops that are sprayed is regulated by controlling the pressure at which the aqueous solution passes through the 30 pipes of the spray equipment, the flow rate of the aqueous solution in the pipes and the dosage in the diffusers.
    Depending on the micro-physical characteristics of the fog detected, with the pressure pump, the aqueous solution flow rate and the size of the solution drops are defined
    aqueous to be projected, and by means of the dispenser the amount of reagent to be applied. DESCRIPTION OF THE DRAWINGS
    5 To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, in accordance with a preferred example of practical realization thereof, a set of such is accompanied as an integral part of said description.

    Figure 1.- Shows a view of two fixed support structures of the fog diffusion installation.
    Figure 2.- Shows a detail view of one of the fixed support structures of Figure 1.
    Figure 3.- Shows a schematic view of the spraying equipment and the control unit.
    20 PREFERRED EMBODIMENT OF THE INVENTION
    An example of embodiment of the present invention is described below with the aid of Figures 1 to 3.
    The installation of fog dissipation comprises, as seen in Figures 1 and 2, a fixed support structure (1) which in the example of embodiment shown in the figure is of pergola type. In this case, the fixed support structure (1) is a lattice formed by a plurality of bars.
    30 In one embodiment, the installation could be installed on sections of highways or highways that constantly suffer from low visibility problems due to fog. A specific example would be on the A8 motorway in sections of the province of Lugo (Spain) where hot fog generally appears due to elevation that makes driving difficult and increases the risk of accidents. Another example of application could
    Be in airports.
    In the example of the figures, the installation of fog dissipation has a highway section comprising two different roads, one for each direction of circulation. In this case a fixed support structure (1) has been arranged in
    correspondence with each road.
    Likewise, the mist dissipation installation comprises a spraying equipment such as the one shown in Figure 3. Said equipment comprises a water supply 10 (2) connected to a first conduction (3) and which can be a tank of
    water storage, a connection to a pipe or an external water tank, etc. It also comprises a dispenser (4) connected to a storage tank for hygroscopic substances (5) and to the first line (3).
    15 The water is passed through the first line (3) and a certain amount of hygroscopic substance is also introduced with the dispenser. This solution is the one that will be released in the environment to get the drops of water that form the fog to increase in size and precipitate in the form of rain or snow.
    20 The amount and pressure at which the hygroscopic substance is introduced into the first conduit (3) depends on the fog conditions that are present at all times.
    The spraying equipment also comprises a pressure pump (8) connected to the first line (3), configured to drive the aqueous solution with water and the hygroscopic substance of the first line (3) to conduit tubes (7) arranged in the fixed support structure (1).
    Said conduit tubes (7) are connected to a plurality of diffusers (6), also arranged in the fixed support structure (1), connected to the conduit tubes (7) and configured for spraying the aqueous substance.
    Preferably, the mist dissipation installation comprises a visibility and climate sensor (10) that is connected to the control unit (9). When said sensor detects predetermined fog conditions, the control unit (9)
    automatically activates the spray equipment.
    The hygroscopic substances of the aqueous solution are preferably selected from calcium chloride, sodium chloride, ammonium nitrate, urea or a combination of the 5 above. These substances are preferred for the present invention because they are economical and in addition both ammonium nitrate and urea are harmless. More preferably, the aqueous solution used has a combination of ammonium nitrate and urea.
