COMPACT AND AUTONOMOUS DRINKING WATER SUPPLY SYSTEM AND

ELECTRIC ENERGY

DESCRIPTION

OBJECT OF THE INVENTION

The present invention relates to a compact and autonomous system for supplying drinking water and electrical energy, which comprises a seawater desalination plant by reverse osmosis and a generator for the electrical supply, both of the different devices and / or equipment that form the desalination plant as lighting and other electrical consumptions both internally and externally necessary. The object of the invention is to provide a system with the mentioned functions, in which the desalination plant and the generator set are mounted in a transportable and easy-to-install container module anywhere, making a special application in the sparsely populated coastal areas with lack of drinking water or problems with water supply.

ANTECEDENTS OF

THE INVENTION

In many parts of the world, especially in Africa and South America, to name but a few, water scarcity is a serious problem especially in sparsely populated coastal areas where, for their development, many cases for their survival, it is very urgent to find new sources of water, both for human consumption and for agricultural consumption. In many cases, the lack of water also means that there is no power supply.

Obviously, the solution for these two specific cases is the establishment of desalination plants, a system that has now remarkably improved its efficiencies and yields, achieving costs more easily depreciated than a decade ago. It is obvious that in sparsely populated areas with a lack of drinking water, the cost of a cubic meter of water is insignificant given the fact that it is necessary for water. 2 012879

DESCRIPTION OF THE INVENTION

The system object of the invention has been designed to solve this problem in a fully satisfactory manner, based on a reverse osmosis desalination plant which is mounted in a container module which is transportable and implantable anywhere, module that also houses a diesel generator set for the electrical supply of equipment and / or equipment of the testing plant and for the electrical supply of lighting and electrical consumption of the interior of the own container and the outside. Obviously, the system is provided with adequate means for their direct connection to a general power supply network.

The container module is internally divided into two independent zones or compartments, one for the generating unit and the other for the desalination plant, comprising forced ventilation means in the two compartments, constituted by fans that hold an overpressure inside the container module. , avoiding the intake of dust or sand from the outside.

As for the desalination plant, it includes means for moving brine at a standstill, as well as chemical cleaning means, to prevent incrustations and biological fouling caused by the discontinuous functioning of the plant.

The support frame of the components of said machining plant, is materialized based on polyester profiles reinforced with fiberglass, which provides lastability and a high resistance to the structure, by reading in addition to an exceptional behavior for the quiconcerne the appearance of corrosions, requiring minimal maintenance. The desalination plant consists essentially of a seawater collection pump, a filtering system, a 012879 high pressure pump for sending water to the reverse osmosis module and a chemical cleaning pump.

As for the components and elements of instrumentation and control that the desalination plant includes in its hydraulic panel, they are the following: a rotameter for produced water.

A rotameter for water refusal (brine).

A manometer for supplying the supply water (sea water).

Pressure gauges of sand filter and cartridge, as well as input and output of high pressure.

A needle valve and a shunt valve. A housing for sampling seawater.

As for the generator, it should be noted that the whole engine-alternator that is part of said generator, is mounted on an electro-soda bench with vibration dampers, all of which are located on the corresponding plank of the container module, said inner floor ousol presenting the peculiarity that it includes two zones, one for store and the other like manifold of water spills which takes place during the starts and maintenance.

FIG. 4 shows, finally, a representation corresponding to the block diagram of the system of the invention, in which a block can be observed as a representation of the generating set which supplies the various equipment and / or apparatuses of the desalination plant which is part of the system of the invention.

PREFERRED EMBODIMENT OF THE INVENTION According to the figures indicated, it can be observed that the system of the invention comprises a container module (1) which is a rectangular prismatic general body of approximately 15 square meters and a volume of 37.5 cubic meters. which determines the cockpit that can be located in any place, it being transportable and easy to install, including a high level of security and autonomy and easy operation and maintenance. Inside this module (1) container are two independent compartments, one for the desalination plant, the characteristics will be exposed later, and the other for a diesel generator. The process plant is operated by reverse osmosis and its purpose is to reduce the seawater with a production that can be estimated at 15 m3 per day, while the generator is used for the power supply of the desalination plant and for the lighting. and the electrical consumptions also biendu clean (1) container, only from the outside up to 10 kVA. If 1 28? If one wants, the installation is prepared to be connected to the general electrical mains.

This module (1) container further comprises a forced ventilation system to ensure the cooling of all equipment and to maintain an overpressure inside the own container module, obtaining in this way that the ventilation system does not provide dust or sand in suspension.

In any case, the container module (1) also includes biendans in the zone or compartment of situation of the genset that in the zone or compartment of situation desaling plant, grids (2) for the exit of the airvicié.
