Abstract

The finding concerns a device for the purification of external air, for use in areas with a high pollution level such as industrial zones, built-up historical urban areas and the like and in areas where pollution levels must be maintained under the values established by law, such as areas occupied by schools, hospitals and other public service structures. Said device is characterised in that it comprises one or more air treatment units, each one performing a sanitising process through an ionisation action, as well as a filtration action on the same air flow.

Description

Title: DEVICE FOR THE PURIFICATION OF EXTERNAL AIR

The present finding relates to a device for the purification of external air, polluted by various types of pollution such as explosion motor exhaust, fumes from domestic chimney flues, and various types of emission from industrial chimneystacks .

As is well known, one of the most important ecological problems that currently exist is that of atmospheric pollution.

In current technical state of the art various methods have been used to remove pollution from the air, but optimum results have not been obtained up to the present time.

The aim of the present finding is to realise a device able to perform an efficient purification action on external air even in conditions where the pollution levels are considerable. An example of this type of polluted area would be zones where the traffic is very heavy, built-up historical city centres and industrial zones.

The device described in the finding would be applied ideally in such zones, and even in proximity to areas where public services are located, such as schools, hospitals, etc, where the air should be as pollution-free as possible.

A further aim of the finding is to realise a device for the purification of external air with a high purification capacity, which, at the same time, should be compact in size and limited in weight for easy transport to the location where it is required using common means.

Such aims are achieved through the realisation of a device for air purification, characterised in that it comprises one or more air treatment units, each one of which operates to create an ionising action as well as filtration on the same air flow.

Such treatment units are contained within a single encased boxed structure, consisting of a frame covered with metal, wood or plastic material, according to the environmental needs and/or appearance requirements of the environment where the device is to be installed. Openings have been made on the structure to facilitate internal access for filter maintenance.

The invention will be better understood from the description of a possible embodiment thereof, provided purely as an example but by no means limitative, with the aid of the appended drawing plates wherein: Figure 1 (plate I) shows a front and section elevation view of the device according to the finding; Figure 2 (plate II) shows a plan view of the device shown in figure 1; - Figure 3 (plate III) shows a side rear elevation view of the device according to figure 1; Figure 4 (plate IV) shows a perspective exploded view of the device according to figure 1;

As can be seen in figure 1, the device according to the finding identified throughout by the numeral 1, consists of a frame 2, that defines a volume containing a plurality of treatment units 3, for the air flow that is forced through said units by fans 4, equipped with convectors 5 mounted downstream of said units; said air flow enters from the front wall "H" equipped with a grid 6, exits from the rear wall "K" equipped with a grid 7 and adjustable fins 8.

As can be seen in figures 1 and 2, each treatment unit 3 is composed of a container 10, inside which an electrostatic pre-filter 11, an ionisation device 12, and an electrostatic post-filter 13 are positioned in a row in the direction of the air flow. The operation of the device is adjusted through an electronic control gearcase 15, located inside the frame, which is manually commanded by the user acting on an external display 16, or by an infra-red remote control device, in order to adjust the air flow rate according to the pollution levels present in the air.

As can be observed in figure 4, the modular construction of the device is achieved thanks to the fact that single treatment units 3, supported by the sliding guide 20 for extraction, are positioned mutually separate from each other, and therefore they can be varied in number according to the filtering capacity required of the device itself; furthermore the frame 2 is composed of modular horizontal elements 2.1 and vertical elements 2.2, and therefore it can be assembled to form different configurations according to the number of treatment units 3 contained inside the frame.

Obviously other different embodiments are possible, according to the components used to equip the device, while remaining within the context of the claims defined as follows.
