The present invention relates to a filtering device of the air to destroy biological contaminants for closed spaces; such biological contaminants can be viruses, bacteria, spores, mold, fungi and the like.
It is known that protect the health of people who work in confined spaces, such as homes, offices, hospitals, vehicles and aircraft of various types, and other spaces, is an extremely important requirement. Such filtering devices must be installed on the exhaust holes for air ventilation and climate control, and similar systems and devices for closed spaces (accommodations, hospitals and the like) and vehicles (airplanes, trains, ships, military transport vehicles, even in space ships etc), although they are rarely used and, as a rule, are not established, except for certain areas, such as, for example, hospital premises, for the destruction of particles and, in particular, microorganisms contained in the air to protect human health.
Such microorganisms, such as biological contaminants, such as viruses, bacteria, spores, mold, fungi and the like, are, in essence, from the point of view of sanitation, the strongest health hazard for people who, because they can cause disease and infection, affecting, in particular, respiratory system.
Known types of filtering devices mainly include segments of fabric, which is intended for trapping particles and microorganisms present in the air when passing through the mentioned segments.
However, such devices have several drawbacks, as, for example, the filter segments should be cleaned or replaced fairly often, and therefore, they require frequent maintenance, which is done by qualified operators, which leads to high costs. In addition, these segments prevent the passage of air, and often when the device starts previously collected materials are accidentally released into a cleared space, with the subsequent risk to the health of people present. In addition, some devices, which include bactericidal lamp-based UV rays with high energy radiation may produce gases that are harmful to human health, such as ozone, and they are ineffective against certain microorganisms, which, for their deactivation, it requires a longer period of exposure to UV rays.
In EP-A1-0644379 disclosed vacuum cleaning device with a container, on the opposite con the Ah which are the intake grille and outlet grille. Inside the container are: filters, located on the intake grill; the Assembly device located after the filter; suction means for creating air flow through the filters and Assembly of the device between the inlet grill and an outlet grill. The Assembly device comprises, in series air flow: electrical network, providing a high negative voltage to the electrification of particles passing air flow; a pair of opposing plates, the first of which is negatively charged deflector plate, and the second positively charged collecting plate; and bactericidal neon lamp with UV radiation designed to emit light in a passage formed by a pair of opposite plates. The electrical network electrifies (negative charge) small particles in the air stream, which is then discarded deflector plate to the precipitation plate, where they are going and translucent germicidal lamp with UV radiation, which thus kills the microorganisms present in the particle.
The aim of the present invention is to eliminate the disadvantages described above, by creating a device air filter for closed spaces, which ensures complete destruction and guaranteed the th decontamination of microorganisms, that is, provides a complete air filtration, protecting the health of people who work in confined spaces.
