Definitions

  • the invention refers to a composite solar tower chimney which serves as both a solar chimney as well as a solar tower steam boiler for the generation of electrical energy, desalinated water and probably industrial cooling.
  • the conventional, known solar tower cooperates with two axis heliostats, which reflect and focus the solar radiation upon a solar steam boiler which is found at the peak of a tower at a height of 150-250 meters.
  • the solar steam boiler with its solar collectors, heats water for the generation of steam and electrical energy with steam turbines .
  • the common solar chimney correspondingly uses the solar energy for the heating of air in a greenhouse which is found around its base.
  • the air is directed into a chimney of a great height of 600-1000 meters.
  • the difference of the specific weights of the air inside and outside the greenhouse, combined with the height of the chimney itself, creates a great static pressures' difference which is converted into mechanical energy and, by means of a system of wind turbines, into electrical energy.
  • Characteristic to both of the aforementioned systems and the more important cost factor is the high tower which supports the central solar steam boiler of the first system and the high solar chimney of the second. Particularly in the case of the solar chimney, the initial investment of the tower and the greenhouse is cost prohibitive.
  • the renewable forms of energy production engage passive systems for the storing of thermal energy.
  • a characteristic disadvantage of the rotor is that first its movement originates not directly from the warm, humid air ascending inside the tower, but rather indirectly from the dry, external ambient air, which is used for cooling the system and which has anyway a lower temperature and energy in comparison to the air inside the tower.
  • a second disadvantage is that the inner cycle of air which undergoes successive humidifications and dehumidifications is of closed type.
  • the closed cycle is known to be disadvantageous in comparison to the open cycle in that the difference of specific weights between the ascending and descending air currents is dramatically low, and consequently that of the static pressures developed at the base which are responsible for the ascension and acceleration of the air flow.
  • the mounting of the rotor at such a great height on the top of the tower creates vibrations that compromise the stability of the tower itself.
  • the invention described herein aims to reduce the cost and to increase the rate of efficiency by the combination and synergy of both innovative and known systems as well as the common use of their components or of the complete integration of these systems.
  • the composite solar tower-chimney consists of a cylindrical column of considerable height positioned on a base of a greater diameter raised above the ground and open at its circumference. Around this base are found a great number of solar sun-tracing heliostats, reflecting the solar radiation and directing it to a number of solar steam boilers, which are set at different heights outside and around the chimney tower.
  • the solar steam boiler heats up either water for the immediate production of steam or salt solution for the indirect and post dated production of steam and the consequent production of electrical energy by means of a system of steam turbine-generators.
  • the rejected low pressure steam is directed to a conventional ground distillation plant to which it contributes the needed amount of heat and then returns to its closed cycle.
  • Adjacent to and all around the area of the solar tower is constructed a greenhouse of considerable dimension with peripheral openings for the entering of ambient air and is completely covered by a transparent cover.
  • the air is heated in the greenhouse by solar radiation and is directed to the tower chimney, where its thermal energy is converted by means of wind turbines to mechanical energy and finally to electrical energy.
  • the majority of the ground area covered by the greenhouse is covered by both shallow ponds of sea water and special shallow ponds characterized by an increasing salinity with depth, called solar lakes or solar gradient ponds.
  • the humidity that the air received along the way is concentrated in the form of clean desalinated water or is absorbed by some means which contributes to a parallel production of industrial cooling energy.
  • the flow of the water or that of the solution back to the base of the tower moves a water turbine for the generation of significant, additional electrical energy.
  • the system can function as a whole fully and completely, since the waste of one part is a vital element for the other.

Adjacent to and around the base 3 lies a second area 6 defined by a circle of an even greater diameter, on which there are a great number of solar sun tracing heliostats 7.
  • the solar sun tracing heliostats 7 are two-axis mirrors which reflect and direct solar radiation to a solar steam boiler collector 2, which is set outside and around the composite solar tower-chimney 1, at a height Hl from the ground level.
  • the solar steam boiler 2 heats water for the immediate production of steam or salt solution for the indirect and post dated production of steam and the consequent production of electrical energy by means of a system of steam turbine-generators.
  • the rejected low pressure steam is, following the steam turbine, directed to a conventional desalination plant as for example that of distillation, where it provides the needed amount of heat, is thereby condensated and then returns to the closed system of solar steam boiler 2. (This has not been designed).
  • the majority of the area 8 beneath the greenhouse is taken up by a shallow pond of sea water, while a lesser part of the area also takes up special shallow ponds 10 characterized by an increasing salinity with depth. These are, in other words, the solar ponds or solar gradient ponds as depicted « in figures 4 and 5.
  • the greenhouse can possibly even be built upon the sea, where the majority of which would be a floating construction.
  • the air of the greenhouse is heated by solar energy, passes at an accelerating rate over the sea water, and is conducted by means of radialized covered passages 15 to the solar tower-chimney 1.
  • a great difference in static pressures at the base of chimney 1 is created, which by means of a system of wind turbines 4 is in turn converted into mechanical energy and finally into electrical energy.
  • the hot and dry air through its passage over the sea water at a great speed, evaporates and carries along vapors which, by reason of its small specific weight, ascends together with the hot air to the solar tower-chimney.

  • the upper and cooler zone a can function as a cool means of condensation of steam of the thermal generators and of other co-generative complexes. Water of the upper zone a is conducted directly through passages 17 to condensers and returns through passages 18, hotter, to the same zone of the solar pond. The same function can be executed indirectly by means of submerged heat exchangers.
  • the zone a can also receive thermal loads from the wasted brine of the conventional ground distillation plant.
  • the large quantities of water required for the function of this solar pond, both of clean water which evaporates as well as brackish brine for the maintenance of the salt gradient, are provided by the conventional ground distillation plant.

  • the solar tower-chimney and by extent the air passing through it is divided for this purpose into segments and independent currents.
  • the passing air is divided into part or current 24 and into part or current 25.

  • the heat exchangers 22 are found half on a segment inside tower 1, and half on the respective exterior cooling upstreams. These currents are created between tower 1 and its shell Ia or between shells Ia and Ib, respectively, which surround the tower at this height.
  • These secondary chimneys can also not be coaxial but independent and can engage secondary wind turbines 4a as well.
  • the drop collectors 26 and 36 function to collect desalinated water which, with water turbine 32, contribute to the generation of additional electrical energy.
  • the condensation of water vapours from the hot air can also occur indirectly by mean of the conventional method of absorption by hygroscopic solid materials, like silica gel, or hygroscopic fluids, as for example a water-based solution of lithium bromide.
  • Figure 7 is depicted a variation with fluid absorbers.
  • the solar tower-chimney 1 bulges at the height which has been chosen for the absorption of warm air vapours and creates chamber 28.
  • the ascending air is deflected 90 degrees from its path to area 28, guided by the vanes 33 in order to return again to the vertical after having passed the bulge.
  • the solution of the absorber rich but poor in water, is distributed in the form of microscopic droplets by an array of nozzles 30, in order to achieve the maximum possible surface contact.
  • This phase there occurs a release of heat both to the passing air as well as to the absorber.
  • the humidity gives back the heat which it had received in the phase of evaporation.
  • the rich in water mixture of the absorber is directed after water turbine 32 to the system of regeneration and the final reception of desalinated water, while the dense and regenerated solution of the absorber that is created is directed by means of pump 35 and pipe 34 to the nozzles 30 and, consequently, completing the cycle.
  • the process of reception of the desalinated water, or regeneration is connected by the heat of the absorber from other energy sources, both renewable and nonrenewable, and which already exist in other parts of the same plant, in order to produce steam.
  • This phase of regeneration of the absorber will be a part of another general system, or cycle, or part of a cycle producing cooling by absorption, where water is both the cooling medium and also the medium of creation of electrical energy.
  • the system in which the above will ultimately be imbedded will depend upon the needs and priorities of the region of the plant for cooling or electrical energy. Should, for example, one be interested in the production of cooling by absorption, the phase of regeneration of the absorber will be the corresponding "regeneration" of the cooling cycle, while the phase of vapour absorption will be the corresponding "absorption" of the same cycle. Should, likewise, one be interested in the production of electrical energy, the produced steam will expand in a steam turbine.

Abstract

L'invention concerne une cheminée en forme de tour solaire composite constituée du cylindre (1) positionné au centre d'une serre couverte (8). Une chaudière solaire centrale (2) - qui est suffisamment surélevée par rapport au sol et placée à l'extérieur, sur la périphérie du cylindre - recueille le rayonnement d'un grand nombre d'héliostats à deux axes (7) et produit de la vapeur qui peut mettre en mouvement la turbine à vapeur générant de la vapeur; la vapeur rejetée est utilisée pour le fonctionnement d'une usine de distillation de sol classique. La majeure partie de la surface couverte de la serre comprend des étangs d'eau de mer peu profonds tandis qu'une partie moins importante comprend des étangs à gradient solaire utilisés comme lieux de stockage thermique pour le fonctionnement de la cheminée en forme de tour solaire composite (1) et des systèmes co-fonctionnant avec celle-ci. Les étangs d'eau de mer alimentent également la précédente unité de distillation de sol classique avec de l'eau de mer. La température et la vitesse élevées de l'air chaud passant sur la surface de l'eau de mer provoque son évaporation. L'air chaud présentant des taux d'humidité élevés est dirigé vers la cheminée en forme de tour solaire composite (1) où l'énergie mécanique de l'air chaud est convertie à l'aide d'éoliennes (4) en électricité tandis qu'à une certaine hauteur, l'humidité de l'air chaud est condensée ou absorbée par des matériaux absorbants spécifiques afin d'être finalement reçu sous la forme d'une eau purifiée désalinisée tandis qu'un refroidissement potentiel peut être effectué en parallèle. Une puissance supplémentaire est générée par la turbine à eau (32) actionnée par l'eau désalinisée supplémentaire ou par des solutions liquides s'écoulant à nouveau par gravité jusqu'à la structure de base de la cheminée en forme de tour solaire.
