Diseño y construcción de un concentrador solar para aplicación en fotocatálisis

Abstract

Abstract: This research work includes the design, construction and technical evaluation and economical performance of a parabolic trough solar concentrator (PCC) for applications in photocatalysis, through the use of geometric optics equations the parameters were obtained necessary for the design of the parabolic reflector such as focal length, aperture angle and parabolic curvature. 3D modeling in SolidWorks allowed us to design each part of the concentrator of both the support structure and the parabolic reflector, with its real dimensions. In addition, materials were selected such as stainless steel that presents a good reflectivity coefficient, as well as the borosilicate receiving tube as materials that guarantee reflectivity and minimal loss of reflected radiation. Through the experimental tests that were carried out, an increase in the average incident irradiation of 193.72%, which confirms the operation of the solar concentrator, however, the climatic conditions of the place are not the most optimal, On the other hand, the economic analysis showed a relatively low manufacturing cost.
