DESCRIPTION of the industrial invention entitled:

EQUIPMENT FOR SANITATION OF ENVIRONMENTS

DESCRIPTION TEXT

The present invention refers to an apparatus for sanitizing rooms.

As ? known, the ozone ? a very powerful oxidant that has recognized properties? sanitizers, which are increasingly? frequently used in the treatment of air, water, environments and surfaces in general.

Various devices are available on the market that allow you to saturate environments with ozone, oxidizing and making various organic compounds inactive such as: mites, bacteria, fungi, moulds, viruses, etc.

The ozone for? Not ? stable over the long term and therefore is generally produced in situ at the time of use through devices called ozonizers which convert the oxygen in the ambient air into ozone.

There are two main methods for producing ozone: the electric one, which exploits the so-called ?corona effect? or ?discharge corona?; and the photochemical one, which uses UV radiation.

The production of ozone due to the corona effect? nowadays the one pi? commonly used, as it has greater advantages, among which are highlighted in particular greater sustainability? of the equipment used, a pi? high ozone production and greater convenience in costs.

Several devices work by producing ozone through the corona effect, controlling the amount? produced and reconverting the ozone at the end of the treatment cycle into purified air, through its catalysis.

The units? of ozone production through the corona effect have inside them means for ionizing the air present in a cylindrical layer, generally consisting of a capacitive load.

The ozone ? produced from oxygen as a direct result of an electrical discharge which breaks down the stable oxygen molecule and forms two oxygen radicals, which can combine with oxygen molecules to form ozone.

The electrodes used to generate the electric discharge are often cooled by a cooling fluid, typically water or air.

The production of ozone requires a lot of energy and the productivity? of the equipment used for its production? in low proportion.

Among the various factors that influence productivity? of the aforementioned equipment, the pi? important ? perhaps the concentration of oxygen as an incoming gas; other important factors are the?humidity? and oxygen purity, and cooling water temperature.

Task of the present invention ? that of realizing an apparatus for sanitizing environments which overcomes the drawbacks of the cited prior art.

Within the scope of the above aim, a particular object of the invention is that of realizing a device that allows to minimize the energy used and at the same time to maximize the production of ozone.

Another purpose of the invention? that of realizing a device which, due to its particular construction characteristics, is able to ensure the most? extensive guarantees of reliability? and safety in use.

Not the last purpose of the invention ? that of realizing a? Equipment that can be produced using commonly available elements and materials? on the market and which is also competitive from an economic point of view.

The task and the aforementioned purposes, as well as others that will appear better later, are reached by an equipment for the sanitization of environments, comprising a containment structure defining inside it an air treatment chamber in fluidic connection with the external environment through at least one opening in the air. inlet and at least one outlet opening, ozone generator means being arranged inside said air treatment chamber suitable for transforming, in a first operating step, the oxygen contained in the ambient air into ozone, and pneumophore means suitable for generating a flow of ambient air substantially between said inlet opening and said outlet opening, said apparatus being characterized in that it comprises oxygen concentrator means suitable for concentrating the oxygen naturally contained in said ambient air, said oxygen concentrator means being arranged upstream of said ozone generating means, so as to supply said ozone generating means with ambient air rich in oxygen.

The air treatment chamber 3 ? in fluid communication with the external environment through at least one first inlet opening 8 and at least one first outlet opening 9.

Preferably, substantially in correspondence with the first inlet opening 8? there is a dust filter 10, which can be removed for cleaning, which prevents the equipment 1 from clogging.

Inside the air treatment chamber 3 ozone generator means 11 are arranged, which in a first stage of operation of the apparatus 1 are capable of transforming the oxygen contained in the ambient air sucked into the same chamber 3 into ozone through the first entrance opening 8.

In this case, the ozone generating means 11 consist essentially of a corona discharge system, per se? known and not described in detail.

will result? however it is evident to the person skilled in the art that, in a different embodiment of the invention, the ozone generating means 11 could consist of any device suitable for this purpose, such as for example an ultraviolet ray emission system.

Preferably, the temperature of the ozone generating means 11 is regulated by? unit? of control 5 through cooling means, not shown in the drawings.

In the air treatment chamber 3 there are also pneumophore means 12 which substantially have the task of generating an ambient air flow between the first inlet opening 8 and the first outlet opening 9.

In this case, the pneumophore means 12 comprise a first fan 13, which in the first stage of operation of the apparatus 1 forcibly draws the ambient air into the air treatment chamber 3, so that it is blown away. it can be enriched with ozone by the ozone generating means 11, and subsequently expels it into the external environment.

The pneumophore means 12 also comprise a compressor 14, which supercharges the ambient air being sucked in to increase the volumetric efficiency of the apparatus 1.

According to the present invention, the apparatus 1 comprises oxygen concentrator means 20, which are able to concentrate the oxygen naturally present in the ambient air sucked into the air treatment chamber 3 to be treated by the ozone generating means 11.

Advantageously, the oxygen concentrator means 20 are arranged downstream of the compressor 14 and upstream of the ozone generator means 11, so that the latter can be fed with a high quantity of oxygen. of ambient air which, in addition, has a high percentage of oxygen.

In this way, during the first phase of operation, the apparatus 1 can? emit in? the external environment a? high quantity? of ozone-rich air.

In this case, the oxygen concentrator means 20 comprise at least one zeolite adsorbent filter, connected to the outlet of the compressor 14 and to the inlet of the ozone generator means 11, defining a fluidic path schematically illustrated with dashed lines in figure 1.
