Description

WATER SEPARATION BY MEMBRANE DISTILLATION AND
PHOTOVOLTAIC ELECTRICITY
Technical Field
The invention relates to Solar Power Technology, particularly solar power converter stations which are made to satisfy human needs for electric power, potable water and thermal energy. It may be used in coastal areas, in emergency situations, such as on ships, in the army, in the hospitals, and in remote areas, as well as in private institutions.
Background Art
There are existing combined solar powered devices, which have a light transmission external layer installed on the support structure, a photoelectric transmission block installed underneath, as well as a saline solution distillation block with its inlet and outlet pipes (U.S. Pat. Applic. No. 201 1/0120854, B01D3/00, 201 1). These well-known devices provide only electric power and distilled water outlets.
There are also existing combined solar powered devices, which have a light transmission external layer installed on the support structure, a photoelectric transmission block accordingly installed underneath, as well as a flowing heat exchanger block (RU2382953, F24J2/42, 2010; U.S. Pat. Applic. No. 2011/0132434, 2011 ; F24J2/40, 201 1). These devices are known worldwide as PVT (Photovoltaic Thermal technology). The devices belonging to this group only produce electric and thermal energy.
Along with its structural features, the closest analog to the present invention is a solar saline disposal device, which has a light transmission external layer installed on the support structure, underneath is a saline solution distillation block with its inlet and outlet pipes, and underneath that, is a flowing heat exchanger block (AM252U, C02F1/00, 201 1). The distillation block has a multistage membrane with a temperature transmission layer located on front and back sides.

Accordingly, in using any of the above devices it is necessary to have one additional device to satisfy the three basic human requirements, namely electric power, potable water and thermal energy.

According to a second aspect of the invention, the distillation block is comprised of a multistage membrane and a thermal transmission layer located on its front and back sides. According to third aspect of the invention, the component layers and blocks of the device may be made as either flat, cylindrical or a combination thereof, and may include a double implemented light transmission external layer.

Detailed Description of the Invention
The device disclosed herein, and diagrammatically shown on Figures 1 and 2, is comprised of the following components: device structure 1, supporting structure 2, light transmission external layer 3, photoelectric transmission block 4, saline solution distillation block 5 and heat exchanger block 6. The layers and blocks of the device are assembled according to descriptions provided below.
The photoelectric transmission block 4 consists of an absorber 7 with photoelectric cells attached on top and installed on the front of distillation block 5. The said block includes an electric outlet 8 for transfer of electricity to an accumulator for electrical distribution use. There exists a gap 9 between the absorber 7 and the light transmission layer 3.
The distillation block 5 is implemented with a multistage membrane with the latter made of layers of successive similar stages. Each stage includes a layer of micro porous membranes 10, which are covered with a support netting layer on both sides 11. The stages are separated from each other by condensing layers 12. Figure 2 exemplifies the flat layer implementation of the distillation block with a three-stage structure. In Figure 4, the cylindrical implementation of the layers of the distillation block having a two-stage structure is demonstrated. Each stage of the distillation block incorporates a saline solution inlet pipe 13, a distillate outlet pipe 14 and a saline solution outlet pipe 15. The corresponding pipes are combined by collectors (not demonstrated in Figures 2 and 4). The front distillation block, which is oriented towards the falling solar rays, is bordered by absorbers 7, the surface of which is directed towards the first stage of the block and is implemented in a grooved manner, as graphically presented in Figures 2 and 4. The back of the distillation block, which is directed towards the heat exchanger 6, is bordered by a condensing layer 16, the structure of which is identical to the structure of the absorbers 7.
The heat exchanger block 6 is bordered by layers 16 and 17 and incorporates the inlet 18 and the outlet 19 pipes.
The contacting surfaces of the blocks are glued with a thermal transmission glue and the gaps between the edges of the layers are hermetically sealed, for example, by hermetic silicon 20.
The device disclosed herein can be made both by flat (Figures 1, 2, and 5) and cylindrical (Figures 4, 6 and 7) implementation of the layers and blocks. In the case of cylindrical implementation the layers and blocks are coaxial.
The structure of the light transmission external layer 3 includes also an implementation with its double layers and vacuumed gap 21, shown in Figure 3, which allows reducing the loss of thermal energy. Such implementation is equally applicable to both flat and cylindrical options of the device implementation. In the case of a device with the implementation of flat layers and blocks 17, the back layer of the heat exchanger is heat-isolated by a layer 22.
The support structure in the cylindrical implementation is carried out in the form of a mirror parabola cylinder as schematically shown in the Figures 5 and 6. Moreover, the package of the successive layers and blocks of the device is installed by means of cantilevers 23 both by flat (Figure 5) and cylindrical (Figure 6) implementations, length-wise of the focal axis of the parabola cylinder. As shown in Figure Ί, in order to increase the productivity, the device may be made of modules linking each other to form a single unit. In another example of implementation, the support structure 2 is - implemented in the form of a mirror paraboloid, as shown in the Figures 8 and 9.
In yet another embodiment of the invention, there is disclosed a simplified method of implementation, wherein the support structure 2 is implemented in the form of a pyramid, as shown in the Figure 10. In this structure a flat mirror system is used. Where a shorter height of device is needed, the support structure 2 is implemented in the form of a Fresnel lens, as shown in the Figure 11.
Both the flat and cylindrical implementation modes of the block operate according to the same principle. The device according to this invention operates on the basis of maximum consumption of solar power. Accordingly, the energy that has not been consumed in the photoelectric transmission block 4 is transferred to the first stage of the distillation block 5 by means of absorbers 7, and then to the successive stages, in accordance with their arrangement order. In the last stage of the distillation block, the unused energy is transferred to the heat exchanger 6 by means of the condensing thermal transmission layer 16. It is clear that during those transfers the temperature potential drops down from block to block and the heat exchanger layer 6 has the lowest potential. However, methods for the regulation of heat- transmission temperature are widely known and may be applied to minimize such a drop in the temperature potential. The small surface area of the side of the device ensures the minimal loss of thermal energy from the sides of invention.
The structure of the device helps providing it with a block following the sun.
The invention with reference to the accompanying drawings offer a high level of applicability as a combined solar powered device, wherein the blocks for receiving potable water, thermal and electric energy are combined in one compact and mobile device. The device also has a high level of energy efficiency since the captured solar energy is used efficiently thus incurring a minimal energy loss.
