Definitions

  • the present invention relates to a system for purifying air from odors and polluting elements, and to a method associated thereto.
  • the present invention is advantageously applied in air purifying treatments in working environments with a high concentration of polluting gases and odors, such as, for example, industrial working areas or zones dedicated to cook food in kitchens of hotels, restaurants, bars and the like, and in air conditioning systems to which explicit reference will be made in the following description without therefore loosing in generality.

  • the currently known methods for purifying air in working environments with high concentrations of polluting substances generally include aspirating the air from these zones, by means of appropriate aspirating hoods or similar means, subjecting the aspirated air to known cleaning processes, which in many cases also include using water scrubbers, activated carbon, and mechanical filters, and diffusing such an aspirated, partially cleaned air outside. These methods have many major drawbacks.
  • the mentioned air cleaning processes are often not perfectly effective, i.e. not capable of purifying the air present in the environments with high concentrations of polluting substances, such as, for example, the kitchens of hotels, restaurants, bars and the like, in food processing industries and air conditioning systems, in which cooking fumes or odorous vapors are dispersed, which are extremely dangerous for humans because the foul air contains harmful gases, such as carbon monoxide CO and carbon dioxide CO 2 , nitrogen oxide NOx, or fine dusts PM10, PM2,5, PM1, or VOC (volatile organic compounds) resulting from the cooking of food or from polluted air.

  • Electrically motorized air lock means 1 are provided along the pipes in various points thereof, in order to adjust the air amount or delivery of the flow F in the system C.
  • the path P of the air flow F and thus the system of pipes C i.e. from pipe C1 to pipe C3, depart from A and advantageously ends in A itself, as better described below.

  • filtering means 7a e.g. of the activated carbon type
  • the airborne ozone blowing unit 2 is adapted to perform the first cleaning treatment on the polluting substances present in the flow F of air taken from A by means of an introduction in the flow F directly into the system of pipes C, specifically at the point of pipe Cl

  • dome-like member 15 arranged over an end part t of pipe C1 protruding over the level of ozonized water arranged in tank 13; such a domelike member 15 with concavity facing downwards and partially immersed into the water bed is adapted to promote a downward oriented diffusion of the air already pre-treated by units 2 and 3, atomized with ozonized water (arrows f in figure 3) so as to favor its scrubbing by precipitation and dissolution of polluting substances in the tank 13 underneath,
  • Tank 13 further comprises a sensor 21 adapted to measure the pH degree of acidity of water, connected to an automatic dispenser which draws a chemical product for keeping the predetermined values, and an overflow 22 for keeping the water level in tank 13.

  • Tube 23 is provided with a first electrically connected, cylindrical net 26 arranged coaxially inside the tube 23 itself, and a second electrically connected, cylindrical net 27 arranged coaxially outside the tube 23 itself, so as to determine a "double crown effect" (figure 4A).
  • Such a double crown effect generates a correct amount of ozone, optimal for obtaining a purifying effect of air, because an air flow interacts with the electric field generated both inside and outside the tube 23.

  • the "double crown effect' is thus obtained by means of such a generator 30 having a double plate or a "bed of nails".

  • Unit 6 is further connected by means of channeling tubes 28 to an ozone diffusing device, indicated by numeral 10 as a whole in figure 1 , and provided with diffusers 10a for diffusing correct, allowed amounts of ozone into environment A and surroundings, as a further service of deodorizing, hygienizing and sanitizing the treated environments.
  • Sensor means 9 is provided to check that the amount of ozone introduced in A with the recirculated air is within the strictly allowed parameters provided by law. Otherwise, if such a parameter is exceeded, the internal recirculation with the cleaned air is immediately stopped and the air is either totally or partially ejected and the recirculation is totally or partially carried out by using an external withdrawal.
  • the system IM includes actuating and control means 8, adapted to control and actuate the operation of the whole system IM, and thus in particular of the mentioned units 2, 3, 4, 5, 6 and 7, and also the operation of the air lock 1 , which adjusts the flow rate in the system of pipes C, and of sensor 9; the system IM is further provided with a module 12, provided on a further pipe C4 connected to the aspirating means B and adapted to recover heat.
  • the system IM the operation of which follows an operating method which is easily inferable from the description of the above-described units of the series S, thus substantially aspirates the flow F of polluted air from A along the path P, blows airborne ozone into it, then atomizes it with ozonized water, and then subsequently carries out purifying scrubbing and decantation thereof (unit 4), followed by filtering by means of activated carbon (unit 5) and a possible mixing with clean, purified air drawn from the outside (unit 7), to completely re-introducing it into the same environment A, either totally or in part.
  • the air re-introduced in A after the purifying and cleaning treatment by means of the system IM is thus effectively purified from polluting substances, and thus perfectly healthy and breathable, of substantially better quality than outside air, thus making the indoor environment A healthy and pleasant.

  • the environment A is specifically a restaurant kitchen, industrial plants or the like, i.e. an environment where the polluting substances are mainly those deriving from cooking operations, air conditioning operations or similar treatments. Therefore, only a further system of aspirating, filtering hoods 30 is advantageously added to the system IM well described above with reference to figure 1 , applied close to and over the kitchen appliances, e.g. the cooking range 31 intended for cooking food or an oven 32.
  • hoods 30 are particularly connected to the system of pipes C, at pipe C1 and pipe C3, which in such a configuration are further and variably connected to each other, thus defining an optimal continuous recirculation of cleaned air.
