Description

SISTEMA, METODO E PRODOTTO PER LA DECONTAMINAZIONE DI AMBIENTI DA CONTAMINAZIONI BIOLOGICHE E CHIMICHE SYSTEM, METHOD AND PRODUCT FOR THE DECONTAMINATION OF ENVIRONMENTS FROM BIOLOGICAL AND CHEMICAL CONTAMINATIONS

DESCRIZIONE DESCRIPTION

La presente invenzione à ̈ generalmente applicabile al settore tecnico della decontaminazione, ed ha particolarmente per oggetto un sistema ed un metodo per decontaminare superfici sensibili di grandi ambienti da contaminazioni biologiche e chimiche. The present invention is generally applicable to the technical sector of decontamination, and has particularly as its object a system and a method for decontaminating sensitive surfaces of large environments from biological and chemical contamination.

L’invenzione ha altresì per oggetto un prodotto decontaminante impiegabile in tale metodo e sistema. The invention also relates to a decontaminant product that can be used in this method and system.

In generale, il metodo ed il sistema in accordo con la presente invenzione potranno consentire un’efficace decontaminazione di ambienti aventi un volume a partire da 100 m<3>. Ad esempio, grazie alla presente invenzione sarà possibile decontaminare efficacemente l’interno di un aereo oppure la torre di controllo di un aeroporto. In general, the method and the system according to the present invention will allow an effective decontamination of environments having a volume starting from 100 m <3>. For example, thanks to the present invention it will be possible to effectively decontaminate the interior of an aircraft or the control tower of an airport.

Potrà essere prevista una fase di atomizzazione micrometrica del prodotto decontaminte nell’ambiente da decontaminare in modo che le superfici esposte possano essere uniformemente ricoperte senza presentare sovraspruzzaggio, effetto di run-off e gocciolamento all’ugello. A micrometric atomization phase of the decontaminated product may be envisaged in the environment to be decontaminated so that the exposed surfaces can be uniformly covered without presenting overspray, run-off effect and dripping to the nozzle.

Allo scopo, potranno essere impiegati mezzi applicatori 10 aventi uno o più ugelli ad ultrasuoni 20 posti nell’ambiente da decontaminare A. For this purpose, applicator means 10 may be used having one or more ultrasonic nozzles 20 placed in the environment to be decontaminated A.

Tali mezzi applicatori potranno essere operativamente collegati a mezzi atomizzatori 30, che atomizzeranno il prodotto decontaminante in modo che gli ugelli 20 dei mezzi applicatori 10 potranno spruzzare lo stesso prodotto sotto forma di microgocce. These applicator means can be operatively connected to atomising means 30, which atomise the decontaminating product so that the nozzles 20 of the applicator means 10 can spray the same product in the form of micro-drops.

I mezzi atomizzatori 30 potranno essere configurati in modo che le gocce del getto atomizzato del prodotto decontaminante presentino un raggio medio molto piccolo, preferibilmente inferiore ai 200 µm ed ancor più preferibilmente circa 20-100 µm, in modo da mostrare un’altissima superficie specifica reattiva. The atomising means 30 can be configured so that the drops of the atomized jet of the decontaminant product have a very small average radius, preferably less than 200 µm and even more preferably about 20-100 µm, so as to show a very high specific surface. reactive.

Il prodotto decontaminante potrà essere ottenuto mediante miscelazione in linea di acqua ossigenata (perossido di idrogeno, H2O2) con un attivatore in fase omogenea, in modo da formare nella soluzione radicali idrossilici ad altissima attività. In una forma di realizzazione preferita ma non esclusiva dell’invenzione, tale attivatore potrà includere solfato ferroso. The decontaminating product can be obtained by mixing in-line hydrogen peroxide (hydrogen peroxide, H2O2) with an activator in a homogeneous phase, in order to form highly active hydroxyl radicals in the solution. In a preferred but not exclusive embodiment of the invention, such activator may include ferrous sulfate.

I radicali idrossilici, quando incontrano gli agenti tossici o biologici, reagiscono secondo reazioni di ossidazione specifiche per il tipo di sostanza da disattivare. When hydroxyl radicals meet toxic or biological agents, they react according to oxidation reactions specific to the type of substance to be deactivated.

Il perossido di idrogeno e l’attivatore potranno essere contenuti in rispettivi contenitori 41, 42 in materiale plastico o metallico, dai quali potranno essere prelevati ed inviati a mezzi di miscelazione 50 operativamente collegati ai mezzi di atomizzazione 30 ed a quelli applicatori 10. The hydrogen peroxide and the activator can be contained in respective containers 41, 42 made of plastic or metal material, from which they can be withdrawn and sent to mixing means 50 operatively connected to the atomization means 30 and to the applicator means 10.

Opportunamente, i mezzi di miscelazione 50, quelli di atomizzazione 30 e quelli applicatori 10 potranno appartenere ad un’unica apparecchiatura 100, la quale potrà essere configurata per essere mobile. La dimensione dell’apparecchiatura 100 varierà a seconda delle esigenze. Conveniently, the mixing means 50, the atomization means 30 and the applicator means 10 can belong to a single apparatus 100, which can be configured to be mobile. The size of the equipment 100 will vary according to the needs.

Per regolare le condizioni ambientali e/o per condizione di elevata umidità relativa e/o per aumentare la turbolenza delle microgocce, il sistema potrà prevedere un apparato di riscaldamento 200, preferibilmente del tipo a turbina, da disporre all’esterno o all’interno dell’area di decontaminazione. To regulate the environmental conditions and / or for conditions of high relative humidity and / or to increase the turbulence of the micro-drops, the system can provide a heating apparatus 200, preferably of the turbine type, to be placed outdoors or indoors. inside the decontamination area.

Il trattamento decontaminante avviene sia per saturazione dell’ambiente che per deposizione diretta, in ogni caso senza la presenza dell’uomo. Eventualmente, potrà essere possibile robotizzare l’apparecchiatura 100, in modo da comandarla da remoto. The decontaminating treatment takes place both by saturation of the environment and by direct deposition, in any case without the presence of man. Eventually, it may be possible to robotise the equipment 100, in order to control it remotely.

Il dosaggio della sostanza attiva e del catalizzatore potrà avvenire con estrema precisione per massimizzare il processo di decontaminazione. L’apparecchiatura 100, pur di facile utilizzazione, potrà essere gestito da un sistema automatico di controllo e supervisione in modo da ottimizzare i principali parametri di processo, e potrà essere programmabile. The dosage of the active substance and the catalyst can be done with extreme precision to maximize the decontamination process. Although the equipment 100 is easy to use, it can be managed by an automatic control and supervision system in order to optimize the main process parameters, and can be programmable.

Opportunamente, l’apparecchiatura 100 potrà essere collegata ad un generatore di corrente 150. Conveniently, the apparatus 100 can be connected to a current generator 150.

Vantaggiosamente, il sistema potrà includere l’apparato decontaminate SX34 CBRN commercializzato dalla Cristanini® per le aree particolari come il cockpit ed eventuale strumentazione portatile. Advantageously, the system may include the SX34 CBRN decontaminated apparatus marketed by Cristanini® for particular areas such as the cockpit and any portable instrumentation.

In una forma di realizzazione preferita ma non esclusiva, poi, il sistema potrà includere un apparato riscaldatore utilizzato nella fase di decontaminazione ed in quella di post-decontaminazione. In a preferred but not exclusive embodiment, then, the system may include a heating apparatus used in the decontamination and post-decontamination phases.

L’invenzione à ̈ suscettibile di numerose modifiche e varianti, tutte rientranti nel concetto inventivo espresso nelle rivendicazioni allegate. Tutti i particolari potranno essere sostituiti da altri elementi tecnicamente equivalenti, ed i materiali potranno essere diversi a seconda delle esigenze, senza uscire dall'ambito di tutela del trovato definito dalle rivendicazioni allegate. The invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept expressed in the attached claims. All the details can be replaced by other technically equivalent elements, and the materials can be different according to the requirements, without departing from the scope of protection of the invention defined by the attached claims.
