The invention refers to an innovative air filtering system using specific frequencies and temperatures capable of eliminating most of the pathogens and dust that can be harmful in sterile environments such as hospitals.

Known art

The sanitization of public places is becoming, in recent years, an essential aspect for the community. Given the large number of public places due to tourism or health emergencies, ? Is it necessary to constantly use disinfection procedures for objects and places where the most? contacts between people.

One of the techniques used for this disinfection process? the use of chemical agents, which cause a continuous waste of resources and materials, including plastic.

In the last few years ? more and more the use of type C ultraviolet rays is common to eliminate bacteria and all the microorganisms present, as in the case of the UV germicidal lamp registered in the relative patent AU2020102582. The germicidal UV? supplied by a mercury vapor lamp which emits UV at the germicidal wavelength. Many germicidal UV lamps use special transformers to ensure a constant flow of electricity. and keep the wavelength constant. But since germicidal UV has a narrow bandwidth, power fluctuations could make disinfection ineffective. The UV rays are extremely harmful for the operator who carries out the disinfection of the sanitary premises.

Ventilation ducts have been developed capable of sanitizing the air contained inside the rooms.

The ventilation ducts developed, in addition to requiring a network of ducts branching through the entire building, include only a fan, to facilitate air circulation, and a filter.

Said filter? commonly used to trap dust and mites contained in the filtered air stream, without being able to eliminate the bacteria in any way.

Purpose of the patent? therefore that of solving the problem of disinfection of the air through the use of various technologies such as ultraviolet rays, infrared rays, infrasounds (5-30Hz), heating (250?C) and mechanical filtration designed to eliminate more ? of 99% of the pathogens present in the room being disinfected, placing the bacteria at specific frequencies and temperatures which cause their extinction.

Said system? also modular and installable on any ventilation system already? existing, without the need? of a network of ducts branching out throughout the building.

Description of the invention

According to the present invention , a system for filtering air from pathogens and dust is provided which effectively solves the above problems. The system in question comprises a mobile cabin, equipped with wheels, able to be moved in the rooms where ? necessary to filter the air. On each cabin are placed a plurality? handles along the corners, designed to facilitate the movement of the cabin by the operators.

Said cabin? covered by a plurality? of press-folded and bolted sheet metal panels. The panels, preferably in aluminium, guarantee the cabin rigidity? and robustness capable of withstanding all the stresses of the internal filtering devices, without compromising their mobility. In fact, the final weight of the cabin is around 150 kg.

The innovative system for filtering air from pathogens and dust? been designed and built to be inserted both in a ventilation system already? existing, which installed individually in the environment; the coupling between the machine and the existing systems takes place via special adapters which connect the air ducts of the ventilation system to the ducts of the cab.

Said system? fit to be modular, ? foreseen in fact the? coupling of a plurality? of cabins in order to increase the air flow and the capacity? filtering the entire system.

Inside the cabin, after the air inlet duct, ? Is there a device capable of making the air molecules and therefore the pathogenic molecules resonate, calibrated on a frequency range which preferably goes from 5 to 30 Hz, and therefore imparting a signal power to the resonant molecules such that there is that resonates is broken.

Once subjected to resonance, the air encounters an ultraviolet lamp which emits a frequency beam with a wavelength of 254 nm, and then an infrared radiator.

Subsequently, inside the cabin, ? installed a finned heater, which generates a heat barrier that reaches 250?C in order to eliminate the bacteria left in circulation.

Downstream of the finned heater ? there is a filter, preferably H14, with an efficiency of not less than 99.995%.

Said filter? designed to trap dust mites and particulate matter in the air. Given the quantity? of harmful waste present inside said filter, replacement would be a dangerous phase for the operator in charge. To work around this problem? a hatch is provided on the external surface of the cab to replace said filter by means of a procedure called, in jargon, ?bag-in bag-out?, allowing the operator never to come into direct contact with the dirty filter.

A differential pressure gauge? installed near of said filter and ? capable of detecting the necessary pressure to be impressed on the air so that? manages to pass through said filter; the purpose of this differential pressure gauge is to monitor the state of deterioration of the filter and to provide for its replacement when the pressure required to be applied to the air is excessive.

The last component present inside the booth before the air comes out? the centrifugal fan. Said fan, preferably with MAC B 225 type polyethylene scroll, ? soundproofed with a sound level of 60dB, and ? able to favor the circulation of the air during the filtering phases. The air flow can? vary according to the type of fan applied or according to the speed? of rotation of said centrifugal fan.

The air filtering system comprises, inside said cabin, a plurality of of sensors including particulate sensors and thermocouples, suitable for detecting the temperature and monitoring heat exchanges.

All the information collected by the particulate sensors, by the thermocouples and by the differential pressure gauge, are recorded by at least two electronic boards which, in one of their embodiments, are able to send the recorded data to a central control unit, via wireless connection, which operates remotely in order to monitor the operating status of the entire machine.

? there is also a USB port which, in one of its embodiments, can? be used to read the information obtained from the sensors via cable connection.

? important to underline that the use of the air filtering system from pathogens and dust? suitable for use in any place that requires a sanitization process including, by way of non-limiting example, hospitals, offices, schools, airports, shops and stations.

The advantages offered by the present invention are evident in the light of the description set forth up to now and will be even more clear thanks to the attached figure and the detailed description.
