Sistema de destilação solar com pré-aquecimento emconcentrador cilindro parabólico

摘要

Due to the increasing need to promote the use of resources that support theenvironment and the clean industry, the science has developed in the area of natural resourceuse as well as enhanced use of the renewable energy sources. Considering also the great needfor clean water and wide availability of salt or brackish water, added to the great solar energypotential in northeastern of the Brazil, it was developed a solar distiller whose main differenceis its system of pre-solar heating also. From experimental adjustments, the system wasdeveloped by the use of a cylindrical solar concentrator coupled to a conventional distiller.The system is designed such that attempt to facilitate the process termination trap to ensureconstant movement of the fluid mass and thus enable higher temperatures to the system andthus fetch a higher amount of distillate collected. In a stage of the experiment were used aforced circulation to try to further increase the amount of energy exchange system. Todevelop the study were set up four settings for comparison in which one was only distillersimple as basic parameter, the second proposed configuration were with the coupling of theconcentration triggered manually every 30 minutes to monitor the sun, the third configurationoccurred with automatic triggering of a timer, and the fourth configuration was also used apumping system that tried to improve the circulation of the fluid. With the comparativeanalysis of the results showed a gain in the amount of distillate system, especially in theforced model
