Descrizione dell'invenzione industriale dal titolo: CELLA CON CONTROLLO DI PROCESSO PER L'ATTIVAZIONE ELETTROCHIMICA DELL'ACQUA Description of the industrial invention entitled: CELL WITH PROCESS CONTROL FOR ELECTROCHEMICAL ACTIVATION OF WATER
Descrizione Description
E' stata descritta (US4663091 , 5 maggio 1987, Humidifier for removing bacilli from water) un'invenzione avente per obiettivo quello di disinfettare, mediante acqua sottoposta ad elettrolisi, per mezzo di due elettrodi immersi nel liquido. Tale tecnologia è stata adoperata per pulire e sanificare superfici di varia estensione per mezzo di acqua del rubinetto sottoposta ad elettrolisi poco tempo prima di essere utilizzata, non addizionandola di alcun additivo (US2002185423, US020080060684A1, WO002009152193A1, WO002010077964A1). Il meccanismo di azione dell'acqua appena elettrolizzata non è del del tutto chiarito dall'indagine scientifica: tuttavia è lecito formulare l'ipotesi che le specie ossidanti che si formano agli elettrodi (ad esempio radicali ossidrile OH , idroperossido OOH etc.) vengano portate a contatto con la materia organica da ossidare, prima che esse abbiano il tempo di scomparire per altra via, espletando così la propria azione ossidante sulla materia organica stessa. Il potere ossidante dell'acqua dipende anche dal potenziale applicato agli An invention has been described (US4663091, May 5, 1987, Humidifier for removing bacilli from water) having the aim of disinfecting, by means of water subjected to electrolysis, by means of two electrodes immersed in the liquid. This technology has been used to clean and sanitize surfaces of various sizes by means of tap water subjected to electrolysis shortly before being used, without adding any additives (US2002185423, US020080060684A1, WO002009152193A1, WO002010077964A1). The mechanism of action of the freshly electrolyzed water is not fully clarified by the scientific investigation: however it is legitimate to formulate the hypothesis that the oxidizing species that are formed at the electrodes (for example hydroxyl radicals OH, hydroperoxide OOH etc.) are brought in contact with the organic matter to be oxidized, before they have time to disappear in another way, thus carrying out their oxidizing action on the organic matter itself. The oxidizing power of water also depends on the potential applied to it

controllo della cella. cell control.
Tuttavia, una cella di elettrolisi fornita di due soli elettrodi, However, an electrolysis cell equipped with only two electrodes,
non consente di stabilire con certezza il potenziale di ciascun it does not allow to establish with certainty the potential of each
elettrodo (e dunque le reazioni chimiche che vi avvengono, poiché electrode (and therefore the chemical reactions that take place there, since
queste possono avvenire solo a ben precisi potenziali) ma si può these can only occur at very specific potentials) but it can
conoscere solo la differenza fra i potenziali dell'elettrodo o positivo e quello negativo. Il potenziale è infatti definito a know only the difference between the electrode potentials or positive and negative. The potential is in fact defined a
meno di una costante arbitraria, la quale fa in modo da portare un less than an arbitrary constant, which causes a
elettrodo ad un valore qualsiasi, e l'altro ad un valore uguale a electrode to any value, and the other to a value equal to
questo, meno la differenza di potenziale applicata. Si ricorre this, minus the applied potential difference. It is resorted to
dunque ad un terzo elettrodo, dal potenziale invariante, il quale therefore to a third electrode, with an invariant potential, which
fissi ad un valore qualunque questa costante arbitraria, e set this arbitrary constant to any value, e
rispetto ad esso si stabiliscono i potenziali degli altri with respect to it, the potentials of others are established

chimici che avvengono, può rendere possibile ridurre i cosumi di chemicals that occur, can make it possible to reduce the consumption of
energia, con conseguente maggior durata degli accumulatori, per energy, resulting in a longer life of the accumulators, for
gli apparecchi non collegati alla rete elettrica. appliances not connected to the mains.
Esempio 1. Example 1.
Una cella è costituita da un anodo in tessuto di fibre di A cell is made up of an anode made of woven fibers of
carbonio, un catodo in acciaio inossidabile, sotto forma di tessuto di 100 mesh (1ΘΘ maglie per pollice quadrato), un elettrodo di riferimento di argento/cloruro d'argento, posto in contatto con la soluzione sotto elettrolisi per mezzo di un setto poroso in fibre di vetro. I tre elettrodi sono pilotati da un circuito elettronico il cui schema è rappresentato in Figura 2 ( l:catodo; 2:anodo; 3:elettrodo di riferimento; 4:segnale di controllo; 5:componente elettronico LM358; 6:resistore da 10kohm; 7: condensatore da 470pF; 8:componente LM358; 9: componente BC547; 10:componente BD139) carbon, a stainless steel cathode, in the form of a fabric of 100 mesh (1ΘΘ mesh per square inch), a reference electrode of silver / silver chloride, placed in contact with the solution under electrolysis by means of a porous septum in glass fibers. The three electrodes are driven by an electronic circuit whose scheme is shown in Figure 2 (l: cathode; 2: anode; 3: reference electrode; 4: control signal; 5: electronic component LM358; 6: 10kohm resistor; 7: 470pF capacitor; 8: LM358 component; 9: BC547 component; 10: BD139 component)
L'acqua trattata nella cella elettrochimica viene spruzzata, mediante una pompa ed attraverso un ugello di diametro pari a due decimi di millimetro, sull'oggetto da pulire e sanificare. The water treated in the electrochemical cell is sprayed, by means of a pump and through a nozzle with a diameter equal to two tenths of a millimeter, on the object to be cleaned and sanitized.
Esempio 2. Example 2.
Una cella è costituita da un anodo, un catodo ed un elettrodo di riferimento al calomelano. Anodo e catodo sono costituiti da rete in acciaio inossidabile. L'acqua trattata nella cella elettrochimica viene nebulizzata per mezzo di un getto di gas compresso e due tubi disposti perpendicolarmente. Un tubo è percorso dal flusso di gas, l'altro dall'acqua attivata nella cella. La nebbia di acqua attivata viene spruzzata sull'oggetto da pulire e sanificare. A cell consists of an anode, a cathode and a calomel reference electrode. Anode and cathode consist of stainless steel mesh. The water treated in the electrochemical cell is nebulized by means of a jet of compressed gas and two pipes arranged perpendicularly. One tube is traversed by the gas flow, the other by the water activated in the cell. The activated water mist is sprayed on the object to be cleaned and sanitized.
