DESCRIPTION

OZONIZER DEVICE AND PROCEDURE FOR PURIFICATION OF AN ENVIRONMENT

The present invention relates to an ozonator device and a process for purifying an environment of the type specified in the preamble to the first claim.

Currently known are ozonizing devices and methods for purifying environments, such as apartments, rooms, vehicles and the like, by means of ozonization.

The ozonator devices consist of systems equipped with electrodes capable of transforming gaseous oxygen (O2) into ozone (O3). This transformation takes place in particular through high voltage electric discharges in particular by exploiting the corona effect. The ozonizing devices also comprise a fan or the like to convey the air present in the environment in correspondence with the electrodes and, vice versa, the ozone created in the environment.

The said high voltage electrical discharges allow you to break the intermolecular bond between the two atoms of a molecule of diatomic gaseous oxygen (O2) to create two free radicals of oxygen (O-) which bind with high probability to two other molecules of diatomic oxygen forming two molecules of triatomic oxygen (O3) called, in fact, ozone.

The ozone created has a bactericidal and disinfectant action. It is, in fact, an energetic oxidant and, for living beings, it is highly poisonous.

After disinfection by ozone ? For? necessary to eliminate the same ozone, which can? be harmful to people and animals.

? therefore it is necessary to change the air in the environment, risking to nullify, in some cases, the advantages of ozonation, or wait for the ozone, which is not? stable, naturally decays into oxygen. This procedure takes a few hours, so, for a certain amount of time, it is not? possible to inhabit the environment.

The prior art described includes some important drawbacks.

In particular, the expected part of the decay of ozone to oxygen ? temporally long and, in some cases, harmful. In this period, in fact, the ozone can? corrode structures and cause other problems if left in an environment for too long.

Furthermore, it would be preferable to maximize the germicidal action of the ozonator device.

In this situation, the technical task underlying the present invention? devising an ozonizing device and a process for purifying an environment capable of substantially obviating at least part of the aforementioned drawbacks.

In the context of this technical task ? An important aim of the invention is to obtain an ozonator device and a purification process of an environment which allow a rapid possible habitability? of environments following ozonation.

Another important purpose of the invention ? create an ozonator device and an environment purification process that maximizes the germicidal action of the ozonator device.

The technical task and the specified aims are achieved by an ozonator device and an environment purification process as claimed in the attached claim 1.

Preferred technical solutions are highlighted in the dependent claims.

The characteristics and advantages of the invention are clarified below by the detailed description of preferred embodiments of the invention, with reference to the accompanying drawings, in which:

Fig.1 shows an ozonator device according to the invention.

In this document, measurements, values, shapes and geometric references (such as perpendicularity and parallelism), when associated with words such as "about" or other similar terms such as "almost?" or "substantially", are to be understood as less than measurement errors or inaccuracies due to production and/or manufacturing errors and, above all, less than a slight deviation from the value, measure, shape or geometric reference to which ? associated. For example, these terms, if associated with a value, preferably indicate a deviation of no more than 10% of the value itself.

Also, when used, terms such as ?first?, ?second?, ?superior?, ?inferior?, ?main? and ?secondary? do not necessarily identify an order, a priority? of relationship or relative position, but can simply be used for pi? clearly distinguish between different components.

The measurements and data reported in this text are to be considered, unless otherwise indicated, as performed in an ICAO International Standard Atmosphere (ISO 2533:1975).

With reference to the Figures, the ozonator device according to the invention ? globally indicated with the number 1.

The ozonator device 1 ? adapted to create gaseous ozone for the purification of an environment 10, such as preferably a habitable room, for example of apartments or the like, or vehicles, such as cars, trucks or the like or the like. The term purification generally refers to a bactericidal or germicidal action or the like.

The ozonator device 1 preferably comprises, briefly, a casing 5, ozonator means 2, suitable for transforming oxygen into ozone and arranged inside the casing 5, and UV ray emitting means 3, arranged inside the? casing 5.

The ozonator means 2 are per se known to those skilled in the art. They preferably comprise means for carrying out high voltage electric discharges suitable, in turn, for breaking the intermolecular bond between the two atoms of a diatomic gaseous oxygen molecule (O2) to create two oxygen free radicals (O-) which do they bind with high probability? to two other molecules of diatomic oxygen forming two molecules of triatomic oxygen (O3) called, in fact, ozone. These electric discharges are preferably made by exploiting the corona effect, by means of a plate of insulating material, and electrodes supplied with high voltage.

The UV ray emitting means are also known per se, and can be of the LED, gas or other type. They preferably have an illuminated power of between 0.1 and 100 W.

Preferably, the UV ray emitting means 3 are able to emit rays of the UV-C type, more preferably with emission peak at frequencies between 250 nm and 260 nm, pi? preferably at frequencies of 254 nm.

The casing 5 is preferably a rigid casing in polymeric or metallic material, capable of containing, inside itself, the UV ray emitting means 3 and the ozonizing means 2. It preferably has dimensions of orders of magnitude, in each direction, decimetres or metres. The casing 5 ? at least partially permeable to air, it therefore comprises a wall comprising a grid or the like. The UV rays are, preferably, emitted exclusively inside the casing 5 and not outside the same. Alternatively, they can also be emitted, or only, outside the enclosure 5, for example into the environment 10 to be purified.

The ozonator device 1 also comprises, preferably, conveying means 4, able to convey the air inside said casing 5 to the ozonator means 2 and to the UV ray emitting means 3. They are preferably constituted by fans or the like and preferably arranged inside the casing 5. The operation of the ozonator device 1 previously described in structural terms ? described below.

It defines an innovative purification process of an environment 10 and ? preferably made with the device, specifications and methods previously described.

The purification process comprises a first phase, in which formed gaseous ozone, preferably through the described processes and ozonizing means 2, and ? conveyed the ozone to the environment 10, by simple diffusion or, preferably, through the described conveying means 4.

Consequently, in this phase, ? diffused the ozone in the environment 10 which carries out its purifying action, in itself? Note. While the ozone ? widespread in the environment, preferably, people and animals do not enter the environment 10.

After the first phase, the environment 10 pu? preferably remain closed, and even without the creation of ozone, for a certain period of time, for example for a few hours, so that the environment itself is purified 10.

A second phase, subsequent to and preferably not consecutive to the first phase, comprises the emission of UV rays in the envelope 5. Both the UV rays and the envelope 5 are preferably of the type previously described.

The second phase also preferably comprises the conveyance of air including ozone, preferably through the described conveying means 4 or by natural diffusion, from the environment 10 to the enclosure 5 or in any case to the area where the UV rays are irradiated.

The second stage? therefore preferably carried out following the purification of the air during the first phase and possibly the following period. In this phase, UV rays have a double action: first of all they further purify the air, carrying out a further germicidal action. Secondly, UV rays, in particular of the types described, accelerate the decay of ozone into oxygen. The ozone is transformed then more? rapidly in oxygen, making the environment habitable again.

The ozonator device 1 and the process for purifying an environment 10 according to the invention achieve important advantages.

In fact, the ozonator device 1 and the process described allow a rapid possible habitability? of the environments following ozonation, thanks to the described UV emission means or to the described second phase.

They also allow maximization of the germicidal action of the ozonator device.

The invention? susceptible of variations falling within the scope of the inventive concept defined by the claims. In this context, all the details can be replaced by equivalent elements and the materials, shapes and dimensions can be any.
