EVAPORATORE E CONDENSATORE AD ENERGIA SOLARE PER SOLAR ENERGY EVAPORATOR AND CONDENSER FOR
ESTRAZIONE DI ACQUA POTABILE DA ACQUE EXTRACTION OF DRINKING WATER FROM WATER
SALMASTRE E/O INQUINATE BRACKISH AND / OR POLLUTED
Sistema costituito da elementi meccanici componibili, espandibile per consentire il massimo sfruttamento di aree destinabili alla contemporanea azione di evaporazione di acque non potabili, a causa dell'alta concentrazione di sali e di inquinanti, e della concentrazione del soluto per recupero ed utilizzazione delle salamoie concentrate. Il sistema, denominato “DI.MA.”, è utilizzabile, ad esempio, nelle aree destinabili a saline ed è caratterizzato dalla applicazione del principio di massimo assorbimento dell'energia solare ottenuto mediante captatori costituiti da superfici metalliche ad assorbimento massimizzato grazie al trattamento opportuno delle superfici esposte irraggiamento solare e dalla applicazione di superfici di copertura trasparenti con la doppia funzione della protezione delle superfici assorbenti dagli agenti di disturbo presenti nell'ambiente e della instaurazione dell'effetto serra. Una delle caratteristiche innovative del sistema consiste nel trasferimento dell'energia termica all'acqua mediante contatto diretto tra le superfici dei captatori con l'acqua che deve essere evaporata, aumentando in questo modo la quantità di energia trasferita nell'unità di tempo grazie alla maggiore efficienza di captazione da parte del metallo trattato rispetto alla superficie libera dell'acqua. La seconda caratteristica innovativa del sistema consiste nella modularità degli elementi che consentono di adattare il complesso alla forma del territorio al contorno ed all’area disponibile per l'operazione preposta . La terza caratteristica innovativa consiste nell'aver ricavato la porzione di impianto destinato alla condensazione dell'evaporato nella immediata contiguità dei singoli moduli di captazione energetica e di evaporazione. La quarta caratteristica innovativa consiste nell'aver conferito al complesso la capacità di convogliare l'acqua di origine meteorica al fine di unirla al condensato, ottenendo in tal modo un incremento dell'apporto di acqua destinata alla potabilizzazione. System consisting of modular mechanical elements, expandable to allow maximum exploitation of areas destined to the simultaneous action of evaporation of non-drinking water, due to the high concentration of salts and pollutants, and the concentration of the solute for recovery and use of concentrated brines . The system, called "DI.MA.", can be used, for example, in areas destined to salt marshes and is characterized by the application of the principle of maximum absorption of solar energy obtained by means of sensors consisting of metal surfaces with maximized absorption thanks to the appropriate treatment surfaces exposed to solar radiation and the application of transparent roofing surfaces with the dual function of protecting the absorbent surfaces from disturbing agents present in the environment and the establishment of the greenhouse effect. One of the innovative features of the system consists in the transfer of thermal energy to the water through direct contact between the surfaces of the sensors with the water that must be evaporated, thus increasing the amount of energy transferred in the unit of time thanks to the greater capture efficiency by the treated metal with respect to the free surface of the water. The second innovative feature of the system consists in the modularity of the elements that allow the complex to be adapted to the shape of the surrounding territory and to the area available for the intended operation. The third innovative feature consists in having obtained the portion of the system intended for the condensation of the evaporated product in the immediate contiguity of the individual energy collection and evaporation modules. The fourth innovative feature consists in having given the complex the ability to convey water of meteoric origin in order to combine it with the condensate, thus obtaining an increase in the supply of water destined for purification.
STATO DELL'ARTE STATE OF THE ART
I sistemi di potabilizzazione di acque marine e/o salmastre attualmente utilizzati per la fornitura di acqua potabile per uso civile o industriale sono per la quasi totalità ad utilizzo di energia non rinnovabile. I sistemi di captazione dell'energia solare attualmente realizzati sono di tipo sperimentale e prevedono l'utilizzazione di specchi a concentrazione per ottenimento di elevate temperature da trasferire a fluidi termovettori con sfruttamento del calore latente di fusione del fluido medesimo. Gli impianti hanno elevati costi di realizzazione e di gestione. Gli impianti di estrazione del sale marino sono le tradizionali saline ad evaporazione, caratterizzate dalla bassa produttività per unità di area occupata dovuta al limitato assorbimento di energia solare da parte dell'acqua e soggette a limiti di esercizio dovuti in particolar modo inquinamento del mare in prossimità delle coste. The purification systems of marine and / or brackish water currently used for the supply of drinking water for civil or industrial use are almost entirely for the use of non-renewable energy. The systems for capturing solar energy currently realized are of the experimental type and provide for the use of concentrating mirrors to obtain high temperatures to be transferred to heat-carrying fluids with exploitation of the latent heat of fusion of the fluid itself. The plants have high construction and management costs. The sea salt extraction plants are traditional evaporation salt pans, characterized by low productivity per unit of occupied area due to the limited absorption of solar energy by the water and subject to operating limits due in particular to pollution of the sea in the vicinity. of the coasts.
CARATTERISTICHE DEL TROVATO FEATURES OF THE FOUND
La peculiarità del Trovato risiede nella combinazione delle utilità già accennate: The peculiarity of the Found lies in the combination of the utilities already mentioned:

B) Modularità; C) Condensazione dell'evaporato ricavata all'interno dei moduli; B) Modularity; C) Condensation of the evaporated material obtained inside the modules;
D) Raccolta dell'acqua meteorica senza strutture aggiuntive. Inoltre la caratteristica costituita dalla possibilità del sistema di galleggiare a breve distanza dal fondo. D) Collection of rainwater without additional structures. Furthermore, the feature constituted by the possibility of the system to float a short distance from the bottom.
E) Dotazione del sistema con un bacino in cemento armato dal fondo piatto e carrabile per le operazioni di prelievo periodico del precipitato. Il bacino, realizzato con cemento cellulare o con inerti dotati di alta coibenza e/o arricchito con uno strato di isolante termico verso il terreno, garantisce il mantenimento di utili livelli di temperatura anche durante la notte, consentendo un rapido ripristino dei valori ottimali di resa alla ripresa diurna dell'irraggiamento solare. E) Equipment of the system with a reinforced concrete basin with a flat bottom and suitable for vehicles for the periodic sampling of the precipitate. The basin, made with cellular concrete or with inert materials with high insulation and / or enriched with a layer of thermal insulation towards the ground, guarantees the maintenance of useful temperature levels even during the night, allowing a rapid restoration of the optimal yield values to the diurnal resumption of solar irradiation.
F) Dotazione del sistema con un metodo di reintegro automatico autoadattantesi al livello di fondo dei sali precipitati, che consente di mantenere costante lo spessore di acqua a contatto con gli elementi evaporanti e usufruire di lunghi intervalli di tempo tra le periodiche raccolte. F) Equipping the system with an automatic reintegration method self-adapting to the bottom level of the precipitated salts, which allows to maintain a constant thickness of water in contact with the evaporating elements and to take advantage of long intervals of time between periodic collections.
