Description

State of the art

To date, various solutions have been proposed for the desalination of salt water, often attributable to osmotic processes or evaporation / condensation. cost / benefit ratio of both plant and operation remain onerous. The proposed idea is aimed at drastically reducing the cost / benefit ratio in the production of desalinated water, to be launched in subsequent and appropriate integration processes

Description

The permanent Thermo Desalinator (Fig 1) is a device consisting of several components, which exploit the potential of the considerable energy inputs given by the TermoSuperfici (Fig.l) (evaporation engine), combined with the effectiveness of the TermoPozzo (Fig. L) ( condensation motor), the device strongly operated and powered by renewable sources: 1) prepares a ThermoPozzo (Fig. a layer of natural insulation 2) proceeds to build a right pentagon greenhouse, watertight and insulated (in EPS or similar); inside, on the lower floor there are suitable exchangers (derivatives of the Thermo-surfaces (Fig. 1), corrugated sheets and pipes containing a heat carrier); inside, on the upper oblique walls, there are suitable exchangers (derivatives of the thermosurfaces (Fig. 1), corrugated sheets and pipes containing a heat carrier) completed by gutters for collecting and conveying the condensate water leaked downwards to the outside ; outside, on the upper slopes, the Thermo-surfaces are arranged (Fig. l) (Heliothermic diode, i.e. corrugated sheets and tubes containing a heat carrier covered by a translucent alveolar), designed to collect the heat from direct and diffused solar radiation The exchangers external (Fig. l) and internal, are connected by crossed water connections and circulators. The device is completed by a system of filling, replacement and maintenance of adequate levels of water to be desalted (coming from the sea or brackish water or to be reclaimed) in the lower compartment of the greenhouse. Dynamics: the energy deriving from the upper external layers is brought with mere circulation (in a closed circuit), to the lower internal exchangers (Fig. L) (this will significantly raise the temperature of the salt water contained in the tank), decreeing evaporation and saturation tensions of the environment. The internal upper exchangers (Fig. 1) are kept at lower temperatures thanks to the exchange with the underlying cold well (Fig. 1) (by mere circulation). The vapor will condense and percolate to an appropriate collection point, and conveyed to the outside

Benefits and applications

The device (Fig. 1) finds extensive applications in both residential and industrial sectors, providing for the preliminary phase of production of desalinated water, to be started with subsequent improvements to residential or industrial processes. The cost of the work is very low, it has low operating costs, essentially due to the hydraulic circulation in closed circuits, without prevalence. The process dimensioned in congruous sections and volumes, will allow natural circulation processes, both for the evaporation and condensation circuit. The process mainly makes use of renewable and random sources, easily overcome randomness by feeding the upper internal exchangers at low temperatures and the lower internal exchangers at high temperatures, through thermal waste (hot / cold) deriving from different processes or specially produced, thermal regimes that will be harbingers of high yields
