Definitions

  • the present invention refers to a fog dissolving apparatus.
  • the invention is concerned with an apparatus capable, while working, of progressively and steadily dissolving fog, said apparatus being structured in such a way as to operate on the basis of the mixing and expulsion of hot and cold air at a given rate and temperature.
  • Fog which consists of droplets of water with an average radius of 0.010 mm in suspension in the atmosphere, causes poor visibility and image distortion as a result of absorbing and diffusing the light.
  • the main reasons for fog formation are the presence of condensation nuclei in a high concentration consisting of dust from the soil, particles of sea salts or products from residual combustion and residues from chemical processes; the presence of steam from lakes, rivers, vegetation and from masses of moist air in motion; quick reductions in temperature at sea level or at low atmosphere and wind rate of about 0.5 m/sec.
  • Another proposal has been the use of big burners to cause fog to evaporate, or the use of micro-waves to cause the relevant area to be heated.
  • a further solution in the art consists of changing the micro-physical structure of fog banks by using helicopters.
  • the present invention provides an apparatus substantially consisting of two side-by-side chambers for producing and collecting hot and cold air, respectively, and of a preceding chamber for mixing the two air jets and for discharging the mixed air outside.
  • the specific object of the present invention is a fog-dissolving apparatus comprising a first chamber provided with fan means for collecting cold air and with a first opening for introducing said cold air and a second opening for discharging the same; a second chamber, separated from said first chamber by a partition wall, provided with a burner for heating the air coming from a first opening, with a ventilator and with a second opening for allowing hot air to exit; a third mixing chamber which communicates with the above first and second chambers via the second openings thereof respectively, and provided with an opening for discharging the mixed air out of the apparatus.
  • said first and second chambers are placed side by side and the third chamber is placed in front of them.
  • means can be provided for controlling the rate of said fan means and said ventilator, as well as for regulating the temperature of the hot air obtained.
  • a chamber for producing hot air having a thermostat with feedback on the burner and means for regulating the air temperature, for instance an electronic system of comparison.
  • the modulation of the discharged air shall take place by means of a fan and a filtering system coupled to each other.
  • the apparatus 1 consists of two chambers 2 and 3 placed side by side, and separated from each other by a partition wall 4 and by a preceding chamber 5.
  • Said chambers 2 and 3 communicate with the chamber 5 by means of the openings 6 and 7.
  • the chamber 2 is provided with a centrifugal fan 8 which is driven, throught the belt 9, by the engine 10.
  • the air sucked up, through the window 6, is sent by said fan 8 to the chamber 5.
  • Chamber 3 is provided with a rear window 11 through which air is sucked up and introduced into the combustion chamber 2.
  • the external cooling of the combustion chamber 12 is obtained via the centrifugal machine 16 driven by the engine 17 through the belt 18.
  • the reference number 19 indicates the fuel tank.
  • the discharge of fumes from the burner 13 takes place through the discharge unit 20 connected to the burner 13 via the tube 21.
  • the apparatus 1 is provided with small wheels 22 and handle 23.
  • Reference number 24 indicates the control board.
  • the exit temperature of cold air, as well as the exit rate of either hot or cold air can be regulated according to the requirements by suitable regulation means.
  • the mixing in chamber 5 of cold air (chamber 2) and the dry hot air (chamber 3) and the discharging of the mixed air, in a direction tangential to the surface of the earth (figures 4 and 5) is the basis for the working of the apparatus.
  • a micro-turbulence starts, which causes a push upwards as a result of the difference in composition of adjacent layers of air.
  • the exit rate of air has not to be too high.
