La presente invenzione presenta un processo di dissalazione delle acque marine basato sul principio della osmosi inversa realizzata in centrifughe industriali. Nei prossimi venti anni l'acqua potabile sarà il nuovo oro perché con inquinamento e surriscaldamento della terra dovrà essere conteso il territorio alla crescente desertificazione. Il processo proposto offre i vantaggi di non avere bisogno di energia termica o chimica per realizzarsi, ha solo energia elettromeccanica, dove vantaggiosamente l'energia elettrica può essere generata localmente da impianti eolici o fotovoltaici. The present invention presents a seawater desalination process based on the principle of reverse osmosis carried out in industrial centrifuges. In the next twenty years, drinking water will be the new gold because with pollution and overheating of the earth, the territory will have to be contested by increasing desertification. The proposed process offers the advantages of not needing thermal or chemical energy to be realized, it has only electromechanical energy, where advantageously the electricity can be generated locally by wind or photovoltaic systems.
STATO DELL'ARTE STATE OF THE ART
a) Il processo di dissalazione è noto. Si ottiene l’estrazione del sale dall’acqua utilizzando fonti di calore che cambiano lo stato fisico dell'acqua, o azioni chimiche o azioni meccaniche. Vantaggiosamente il processo a osmosi inversa, che si basa su spingere l’acqua su un filtro chimico con una pressione osmotica necessità di azione meccanica e non fonti termiche di energia. Quindi può essere completamente attivato con energia elettrica, vantaggiosamente ottenibile in zona con impianti fotovoltaici o eolici. a) The desalination process is known. Salt is extracted from water using heat sources that change the physical state of the water, or chemical or mechanical actions. Advantageously, the reverse osmosis process, which is based on pushing the water on a chemical filter with an osmotic pressure, requires mechanical action and not thermal sources of energy. Therefore it can be completely activated with electricity, advantageously obtainable in the area with photovoltaic or wind power plants.
b) Le centrifughe industriali per la separazione di liquidi da solidi hanno vasti campi di applicazione e possono essere a ciclo continuo o discontinuo. Si va dall’ecologia per trattamento di acque industriali alla industria chimica, agli oli combustibili e lubrificanti nonché per alimentazione e bevande, trattamento dei fanghi di perforazione o di oleochimica, prodotti di derivazione animale o prodotti lattieri. In alcuni casi il prodotto finito è il "liquido" e in altri è il "solido". b) Industrial centrifuges for separating liquids from solids have wide fields of application and can be continuous or batch. They range from ecology for industrial water treatment to the chemical industry, fuel and lubricating oils as well as for food and beverages, treatment of drilling or oleochemical muds, animal products or dairy products. In some cases the finished product is the "liquid" and in others it is the "solid".
SINTESI DELL’INVENZIONE SUMMARY OF THE INVENTION
L’invenzione prevede di ottenere la dissalazione dell’acqua marina o lacustre salata col principio della osmosi inversa in cui una azione meccanica porta l’acqua su una barriera filtrante ad azione chimica con una pressione superiore alla pressione osmotica, in modo che la barriera filtrante sottragga gli ioni di sale all’acqua. The invention provides for the desalination of sea or salt lake water with the principle of reverse osmosis in which a mechanical action brings the water onto a filtering barrier with chemical action with a pressure higher than the osmotic pressure, so that the filtering barrier subtract the salt ions from the water.
L’invenzione concerne un processo per la dissalazione di acqua marina salata mediante osmosi inversa comprendente le seguenti fasi: The invention concerns a process for the desalination of salt sea water by reverse osmosis including the following steps:
1) Prelievo di una quantità di acqua marina 1) Withdrawal of a quantity of sea water
2) Pompaggio di detta quantità di acqua marina ed invio ad una prima centrifuga per macrofiltrazione preventiva e sterilizzazione batterica 2) Pumping of said quantity of sea water and sending to a first centrifuge for preventive macro-filtration and bacterial sterilization
3) Pompaggio ed invio dell’acqua marina microfiltrata e sterilizzata ad una seconda centrifuga provvista di uno strato di materiale ad azione chimica per realizzare l'osmosi inversa, 3) Pumping and sending the microfiltered and sterilized sea water to a second centrifuge equipped with a layer of chemical action material to achieve reverse osmosis,
4) Distribuzione dell’acqua dissalata ad utilizzatori finali. 4) Distribution of desalinated water to end users.
L'invenzione prevede di ottenere questa pressione con una centrifugazione con centrifughe industriali come descritte al punto b) del precedente paragrafo. Necessità di sostituire periodicamente l'elemento filtrante porta ad adottare tecnologie strutturali come le centrifughe del mondo tessile, dove c'è un coperchio apribile incernierato lateralmente e una struttura di sollevamento che solleva il cestello rotante fuori dalla centrifuga. Vantaggiosamente a questa struttura di centrifuga descritta in figura 2) si abbina una centrifuga per una macrofiltrazione iniziale. Come descritto in b) del paragrafo precedente e in dettaglio nella figura 1). l'impianto complessivo assume la struttura di quello descritto nella figura 3) dove si va dal mare, elemento 1 di Fig. 2) all'utilizzatore finale (elemento 10 di fig. 3). The invention provides for obtaining this pressure with a centrifugation with industrial centrifuges as described in point b) of the previous paragraph. The need to periodically replace the filter element leads to the adoption of structural technologies such as centrifuges in the textile world, where there is a laterally hinged opening lid and a lifting structure that lifts the rotating basket out of the centrifuge. Advantageously, this centrifuge structure described in figure 2) is combined with a centrifuge for an initial macro-filtration. As described in b) of the previous paragraph and in detail in Figure 1). the overall system assumes the structure of the one described in figure 3) where it goes from the sea, element 1 of Fig. 2) to the end user (element 10 of fig. 3).
