Description
Description
Apparatus for independent production nf at least fresh water through desalination of sea water
Technical Field
This present invention refers in general to processes for production of fresh water by desalination of sea water; it applies to an apparatus for independent desalination. The invention is indicated for, but not limited to, installation aboard seafaring craft and may be combined with an electrical generator so as to provide the vessel itself with a supply of both fresh water and electrical power.
Background Art
Medium-size pleasure craft are known to use water storage tanks and accumulator batteries to meet their main needs for adequate reserves of fresh water and electrical power for starting up propulsion engines.
As craft capacity increases, water storage tanks and accumulator batteries are supplemented with specific sea water desalination apparatuses and specific electrical generators. The former usually work on the known principle of inverse osmosis; the latter are usually diesel-fuelled so as to store only one type of fuel aboard, whether it be for the craft's propulsion engine or for motors driving other features.
Although the construction arrangement described here is commonly used, it has significant disadvantages. In fact, water storage tanks and accumulator batteries occupy space on board (increasing in relation to increasing demand for reserves of both resources) and involve large amounts of dead weight as well as very high plant and equipment costs.
It should be noted that conventional, inverse osmosis desalination apparatuses require a high-pressure pump, which consumes significant amounts of electrical power and makes it vital to have an electrical generator, since batteries on board soon go flat. Moreover, electrical generators cause further problems in that they start up automatically when the accumulator battery levels fall below a predefined minimum. When this happens, especially at night, it disturbs people on the craft or moored nearby.
Disclosure of the Invention
Thus, a primary object of the invention is to desalinate sea water with an original and innovative apparatus suitable to start the desalination process, by exploiting some of the heat generated by operation of the vessel's engine. This simplifies the desalination apparatus's physical structure radically, making desalinated water available when the engine is operating, and also enabling reduction of the water supply storage capacity. Simplification of the apparatus's physical structure will obviously reduce plant and running costs, with a positive effect also on the reliability of the apparatus which, in the seafaring sector, is a crucial safety feature.
A further object of the invention is to provide an energy source, to combine with or replace the main propulsion engine, for powering desalination. This would be a basic, reliable and inexpensive auxiliary engine that could also be used for combined generation ofelectrical power.
An additional object of the invention is to provide a very quiet auxiliary engine, which could be operated at any time of day without disturbing any members of the crew or passengers on nearby craft. The invention has technical characteristics, in line with such objects, that clearly result from the content of the patent claims reported below, in particular claim 1, and from any directly or indirectly dependent claims.

The advantages of the invention will also be more evident in the detailed description that follows, which refers to attached drawings that illustrate some examples but by no means all of the invention's applications, where: - figure 1 is a schematic illustration of the invention;
- figure 2 illustrates some details of the apparatus shown in figure 1.
Detailed Description of the Preferred Fmhodi merits of the Invention ^
With reference to the attached drawings, figure 1 , in general, shows an apparatus 1 for independent production of fresh water through desalination of sea water, preferably for but not limited to use on seafaring craft.
Apparatus 1 essentially includes an airtight container 2, kept under vacuum by appropriate suction means 3 and containing vaporizers 4 suitable to receive heat from an external heat source 6, at high temperature; condenser means 7 for transferring heat to an external heat source 5, at low temperature; a collection tank 8.
Container 2 is supplied with sea water which, on contact with the vaporizers 4, vaporizes, then reaches condenser means 7 in vapour form, where it condenses and then, with salt removed, is collected in collection tank 8. hi particular, container 2 comprises an elongated hollow cylinder 21 , closed at each end by two caps 10, which assumes a vertical position when in use. Caps 10 are flanged and can be coupled to flanges 22 connecting cylinder 21 hermetically but with a removable coupling, so that they can be removed from cylinder 21 for inspecting the inside of container 2. Container 2 is kept under vacuum by said suction means 3, which for this purpose are fitted with a vacuum pump 9 installed near the top of container 2. During use the vacuum pump 9 will create an absolute pressure in the container 2 for achieving vaporization of sea water heated to a suitable temperature by the vaporizers 4.
The vaporizers 4 are installed at the lower edge of container 2. They include a heat exchanger 12, which operates between the high-temperature heat source 6 and the lower inner part of container 2, which contains a section of coiled pipe 23 that is part of the heat exchanger 12. The heat exchanger 12 conveys a heat carrying fluid consisting of a mixture of glycol and water that is heated as it crosses the heat source 6, then transfers most of the heat acquired to the vaporizers 4. The latter, in turn, heat the sea water to a temperature at which it will evaporate at an absolute pressure of approximately 0.07-0.20 bar; this pressure can be maintained using the vacuum pump 9 inside container 2. The condenser means 7 include a heat exchanger 11 , fitted with a copper pipe coil 24 conveying heat carrying fluid, cooled by an external low-temperature source 5, activated by the sea water itself. This is directly drawn from the sea by pump 25, then channelled into a cross-flow heat exchanger 26 and later discharged back into the sea. The heat exchanger 11 also contains a heat carrying fluid made up of water and glycol. The mixture circulating in the heat exchanger 11 is heated inside container 2, drawing heat from the condensing water vapour, conveyed through coil 24. After transiting the cross-flow heat exchanger 26, the water and glycol mixture cools and returns to coil 24, circulating continuously in heat exchanger 11. Figure 1 shows that the vacuum pump 9 is fitted with a suction point 27 for container 2, very near to condenser means 7. This was designed to minimize risks that pump 9 might aspirate uncondensed vapours that can affect correct operation. Apparatus 1 can exploit the exhaust heat of the craft engine as a high-temperature heat source 6 for the heating fluid circulating in heat exchanger 12. A preferred embodiment suggests the use of an independent, external combustion, thermal engine 13 (diesel if possible), suitable for driving an electrical power generator for charging up conventional accumulator batteries fitted in the craft.
Operation of said thermal engine 13 by a Stirling cycle engine would bring further
advantages, both in terms of thermal efficiency combined with production of electrical power, and for the low noise levels that would allow it to be used without limitation. Moreover, apparatus 1 is fitted with sensor means 15 (minimum, maximum) for reading the immersion level of vaporizers 4 in the sea water held inside container 2; sensor means 16 for reading the level of desalinated water inside collection tank 8; lastly, pumping means 17 connected to collection tank 8, to remove desalinated water from container 2.
Apparatus 1, finally, also fits automatic operating control means 18. Said control means 18 - in the event of excess liquid being notified by the sea water level sensor means 15 in container 2 - order closure of the actuator 19, which controls sea water supply to container 2. They also order deactivation of suction means 3 for container 2, and control an actuator 20 that releases the container 2 vacuum, activated in particular by a 3-way valve. Control means 18, after ordering actuator 20 to release the container 2 vacuum, also activate desalinated water pumps 17, subject to the level reading of liquid present in collection tank 8, transmitted by level sensor means 16, associated to tank 8 itself. Apparatus 1 use and operation can be described as follows: the air aspirated at a temperature Taa is preheated by an exchanger 28 with the exhaust fumes from the engine 13. This air, mixed with fuel, will thensupply thermal engine 13. The heat from the exhaust fumes of the thermal engine 13, at the exit of the exchanger 28 at temperature T3, is sent to a compact cross-flow (air/water) heat exchanger 29 containing the same solution (water-glycol at 30%) used to cool the engine 13. The solution, when passing through the engine 13, acquires heat, which added to that recovered from the exhaust fumes provides considerable thermal power that can be used to desalinate sea water.
The invention thus conceived is obviously suitable for industrial application and can also be modified in various ways that achieve variations encompassed by the
invention's concept. Furthermore, all features can be replaced by components of equivalent technical level.
