Description
DISCO COLECTOR DE RADIACIÓN SOLAR. CONCENTRADOR DE MÚLTIPLES HACES INDEPENDIENTES DE RAYOS REFLEJADOS ESPECULARMENTE SOBRE SOLAR RADIATION COLLECTOR DISK. MULTIPLE CONCENTRATOR DOES INDEPENDENT BEAMS OF SPECTULARLY REFLECTED RAYS ON
UN PLANO RECEPTOR FIJO Sector técnico de la invención A FIXED RECEIVING PLANE Technical sector of the invention
La presente invención se encuadra en el sector de la energía solar, concretamente en el sector de los discos colectores de radiación solar. The present invention is part of the solar energy sector, specifically in the field of solar radiation collector discs.
Antecedentes de la invención Background of the invention
Los discos colectores solares son discos parabólicos reflectantes que concentran la radiación solar en un receptor que se sitúa en el centro de la parábola. En este centro puede situarse un motor que se encarga de producir la energía mecánica, transformándola en energía eléctrica. Solar collector discs are reflective parabolic discs that concentrate solar radiation in a receiver that is located in the center of the parabola. In this center a motor can be placed that is in charge of producing the mechanical energy, transforming it into electrical energy.
Se han desarrollado innumerables prototipos de discos concentradores de radiación solar para poder aprovechar, a precios competitivos, las altas densidades de temperatura que se consiguen mediante la concentración por reflexión especular de la radiación directa solar. La orientación necesaria del concentrador para que el aumento de la densidad de energía térmica en el elemento receptor posibilite tratamientos térmicos y procesos de conversión termodinámica a otras formas de energía, requiere de soluciones tecnológicas estructurales fiables, a ser posible autónomas y de mantenimiento mínimo con costes soportables. Countless prototypes of solar radiation concentrator discs have been developed to take advantage, at competitive prices, of the high temperature densities that are achieved through the concentration by specular reflection of direct solar radiation. The necessary orientation of the concentrator so that the increase in the density of thermal energy in the receiving element allows thermal treatments and thermodynamic conversion processes to other forms of energy, requires reliable structural technological solutions, if possible autonomous and minimum maintenance with costs bearable
Los discos concentradores conocidos en el estado de la técnica utilizan como reflector superficies continuas especulares con doble curvatura. Con ellas se ha conseguido tener en los receptores altas densidades de energía. Pero existe un problema con estos discos debido a que la distribución sobre el plano receptor del flujo concentrado que se obtiene con los reflectores especulares parabólicos, por tratarse de óptica de enfoque puntual, no es homogénea. Concentrator discs known in the state of the art use as reflector continuous mirror surfaces with double curvature. With them, high energy densities have been achieved in the receptors. But there is a problem with these discs because the distribution on the receiving plane of the concentrated flow that is obtained with the parabolic mirror reflectors, because it is point-focused optics, is not homogeneous.
Este inconveniente es muy determinante pues imposibilita su uso con concentradores fotovoltaicos así como en reactores que requieran una distribución regulada y homogénea en su superficie receptora. This drawback is very decisive because it makes it impossible to use it with photovoltaic concentrators as well as in reactors that require a regulated and homogeneous distribution on its receiving surface.
Existe otro inconveniente en los discos existentes en el estado de la técnica debido a la dificultad constructiva y los costes de fabricación que supone el utilizar espejos curvados. There is another drawback in the existing disks in the state of the art due to the construction difficulty and manufacturing costs involved in using curved mirrors.
Otro problema más que se encuentra en los discos del estado de la técnica es el consumo eléctrico que requieren debido a que se trata de discos concentradores
giratorios los cuales, para girar sobre dos ejes y para permanecer orientados requieren una electrónica de control y equipos moto-reductores que consumen energía eléctrica, tanto mas cuanto más tengan que impedir desorientaciones causadas por el efecto vela que provoca el viento sobre grandes superficies continuas y móviles. Another problem that is found in the state-of-the-art disks is the electrical consumption that they require because they are concentrator disks. swivels which, in order to rotate on two axes and to remain oriented, require control electronics and moto-reducing equipment that consume electrical energy, all the more so as to prevent disorientation caused by the sail effect caused by wind on large continuous surfaces and mobile phones
Por todo ello, la invención aquí presentada solventa los problemas encontrados en el estado de la técnica debidos a que no poseen una distribución regulada y homogénea del flujo en su superficie receptora, la dificultad constructiva y los costes de fabricación que supone el utilizar espejos curvados y el elevado consumo eléctrico que requieren para girar sobre dos ejes y para permanecer orientados. Therefore, the invention presented here solves the problems encountered in the state of the art due to the fact that they do not have a regulated and homogeneous distribution of the flow at their receiving surface, the constructive difficulty and the manufacturing costs of using curved mirrors and the high electrical consumption that they require to rotate on two axes and to remain oriented.
Descripción de la invención Description of the invention
La invención que se presenta, objeto de esta solicitud, trata de resolver los inconvenientes característicos de los discos colectores existentes descritos anteriormente. Para ello utiliza dos reflectores. El primer reflector de la radiación solar son múltiples superficies especulares planas independientes, las cuales interceptan y desvían los haces de rayos hacia el segundo elemento reflector especular unitario, el cual envía los rayos concentrados al receptor consiguiendo, en una superficie ligeramente mayor a la de una sola de las múltiples superficie reflectoras especulares, la distribución y/o superposición de todos los haces de rayos interceptados y desviados. El movimiento de enfoque de cada pequeño reflector especular es independiente, pudiendo de esta manera distribuir las intensidades de flujo sobre el plano receptor final. La estructura sobre la que se colocan estas superficies especulares planas consiste en una estructura circular radial y lenticular muy ligera sobre la cual van montados y fijos unos aros tubulares redondos concéntricos con una diferencia entre sus radios igual entre ellos. En dichos aros se sujetan, mediante una pinza con doble clip, cada una de las múltiples superficies reflectoras especulares. Cada superficie especular tiene pegado un tramo de tubo que permite su anclaje en el clip de la pinza correspondiente. Con este mecanismo se permite el movimiento de cada superficie especular de manera independiente en dos giros distintos y ortogonales que permiten desviar y fijar manualmente la dirección del haz de radiación solar interceptado por ella hacia el plano receptor. The invention presented, object of this application, tries to solve the characteristic drawbacks of the existing collector discs described above. For this it uses two reflectors. The first reflector of the solar radiation is multiple independent flat mirror surfaces, which intercept and divert the beam of rays towards the second unit specular reflector element, which sends the concentrated rays to the receiver getting, on a surface slightly larger than that of a single of the multiple mirror reflective surfaces, the distribution and / or superposition of all beams of intercepted and deflected rays. The focus movement of each small specular reflector is independent, thus being able to distribute the flow intensities over the final receiving plane. The structure on which these flat mirror surfaces are placed consists of a very light radial and lenticular circular structure on which concentric round tubular rings are mounted and fixed with an equal difference between their radii between them. In said hoops, each of the multiple mirror reflective surfaces is held by a double clip clamp. Each specular surface has a tube section attached that allows its anchoring in the clip of the corresponding clamp. With this mechanism, the movement of each specular surface is allowed independently in two different and orthogonal turns that allow the direction of the solar radiation beam intercepted by it towards the receiving plane to be manually deflected and fixed.
La ventaja de disponer en un plano receptor de toda la energía recogida en un lugar fijo favorece notablemente la instalación de reactores y de los sistemas de conversión y evacuación de la energía.
El punto fijo en un colector con seguidor solar de dos ejes que se encuentra en continuo movimiento es aquel en que estos ejes se cruzan y coinciden. Para situar el plano receptor en el punto fijo del equipo se han diseñado unas estructuras equilibradas provistas de ejes metálicos que giran en soportes con rodamientos atornillados a la estructura que se encuentra anclada al terreno firmemente. El montaje elegido para el seguimiento del colector es el ecuatorial The advantage of having all the energy collected in a fixed place on a receiving plane greatly favors the installation of reactors and energy conversion and evacuation systems. The fixed point in a collector with a two-axis solar tracker that is in continuous motion is that in which these axes intersect and coincide. To place the receiver plane at the fixed point of the equipment, balanced structures have been designed with metal shafts that rotate on supports with bearings screwed to the structure that is firmly anchored to the ground. The assembly chosen for monitoring the collector is the equatorial
