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.
- 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.
- 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.
- Another object of the present invention is to provide a system which is able to ensure the effective application of antipollution laws even in outdoor zones surrounding the mentioned working environments which are to be subjected to air purifying cycles.
- a further object of the present invention is to provide a method of air purification and treatment capable of allowing very effective cleaning of the air in working environments, thus obtaining an air so purified to allow the total or partial recirculation thereof in the environment, establishing a virtuous ecological cycle and saving energy, without causing the pollution of the outdoor zones close to said environments.
- FIG. 1 is a partial sectional front view with some parts removed from clarity and other parts enlarged and therefore shown with a dashed line, of a first embodiment of the described purifying system;
- FIG. 2 is a partial sectional front view with some parts removed from clarity and other parts enlarged and therefore shown with a dashed line, of a second embodiment of the described purifying system;
- figure 3 is a diagrammatic, enlarged-scale view of a constructional detail of the system in figure 1 ;
- figure 4 is a diagrammatic, enlarged-scale view of another constructional detail of the system in figure 1 ;
- figure 4A is an enlarged view of the detail in figure 4.
- - figure 5 is a diagrammatic view of a variant of the detail in figure 4; and - figure 5A shows a detail of the variant in figure 5 on an enlarged scale.
- IM indicates as a whole an air purifying system in an closed indoor environment A, in particular a working environment, e.g. an industrial working area.
- the system IM comprises a plurality S of operating units adapted to the purifying treatment of an air flow F generated within a system C of pipes aspirating the polluted air from the environment A by known aspirating means B, e.g. of the fan type; in particular, the operating units are arranged in sequence along the forward movement path P of the aspirated air flow F circulating in the system of pipes C.
- 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.
- the plurality of units S comprises, in sequence along the path P: - a unit 2 for blowing airborne ozone into the polluted air being aspirated;
- the unit 7 for introducing or reintegrating clean air drawn from the outside into the system of pipes C includes further aspirating means B1 arranged along a pipe C2, is arranged downstream of unit 6, and is preferably connected to unit 6 by means of appropriate tubes so that the air introduced from the outside is advantageously blown with ozone at pipe C2 (see figure 1); furthermore, unit 7 is provided with filtering means 7a, e.g. of the activated carbon type, to define a catalyzing barrier for the photochemically-formed, anthropogenic ozone in addition to other gaseous pollutants and/or odorous organic molecules, and/or HEPA type filters for thin dusts, and preferably also an air heating battery 7b where the air taken from the outside needs to be heated.
- 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
- the unit 3 for water scrubbing the air in the aspiration channel with water blown with ozone and recirculated by means of a pump from the unit 4 is adapted to continue cleaning the polluting substances suspended in the flow F of air taken from A.
- the air scrubbing unit 4 is adapted to abate the polluting substances, such as solid and gaseous fractions, e.g. CO, CO 2 , NOx 1 VOC, PM10, PM2,5, PM1, aldehydes, etc., suspended in the flow F of air taken from A by introducing ozonized water, i.e.
- Unit 4 thus comprises: - a container 4 of the fluid bed type, the bottom of which defines the mentioned decantation tank 13,
- 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.
- the ozone generating unit 6 comprises at least one tube 23 made of dielectric material, arranged in an appropriate closed container 24, in which air from the outside is adapted to circulate by means of grids 25 which feed the air to generate ozone.
- 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 tube 23 and the two nets 26 and 27, coaxial to unit 6, are replaced by a generator 30 formed by two equivalent, opposite plates 31 and 32, each of which is provided with a plurality of ends 33 having tips 34, three tips 34 as shown in the detail in figure 5a.
- Plates 31 and 32 define two positive electrodes between which a foil-like member 35, adapted to define the negative electrode, is arranged.
- the "double crown effect' is thus obtained by means of such a generator 30 having a double plate or a "bed of nails".
- the optimal amount of ozone produced is then advantageously fed and channeled to the mentioned units 2 and 4 by pressurized pump means PP without using compressed air as conveying element.
- the container 24 is further provided with an ozone collecting compartment 24a.
- 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.
- 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.
- ozone diffusers 10a are advantageously provided also in adjacent rooms A1 used as pantries or similar storage areas in addition to the working environments themselves, in which the mentioned means 8 for the programmed actuation in the absence of personnel may be arranged, as shown in the configuration of the system IM in figure 2.
