Abstract
La energía que nos brinda el Sol, resulta ser una de las energías renovables más abundantes a lo largo de nuestro país, por lo que el uso de ésta en distintos procesos cada vez se hace más atractiva, por la facilidad y sustentabilidad que presenta. Esta energía se puede aprovechar como energía térmica o bien fotovoltaica. Este trabajo analiza la factibilidad técnica de un secador para lodo séptico utilizando la energía del sol, el cual se llevará a cabo en una planta de tratamiento de aguas servidas. Para realizar este análisis, es importante conocer todas las variables que se relacionan con el secado solar de lodo, lo que lleva a este trabajo a dividirse en tres secciones bien diferenciadas. Por un lado, conocer el comportamiento de la radiación solar en la zona de la planta a lo largo del año, como también en los meses de estudio. Por otra parte, contar con la temperatura final del aire al ser expuesto a la radiación. Y finalmente obtener los tiempos de secado del lodo en base a lo obtenido anteriormente. A lo largo de este trabajo se darán a conocer los meses con mayor radiación en la localidad del proyecto, el cual es liderado por el mes de enero. Seguido de aquellos resultados que se relacionan con el aumento de temperatura del aire, donde se podrá ver que se alcanzan temperaturas sobre los 60° C e incluso sobre 70° C, dependiendo de la cantidad de aire que circule y el mes en cuestión. Finalmente, se entra en el cálculo de los tiempos de secado para el lodo séptico, los cuales dependen de muchos factores. Se podrán ver las curvas de secado para distintos flujos de aire y cantidades de lodo. Dependiendo del tipo de secador y la cantidad de producto se tienen tiempos de entre 2 – 7 días, para un secador discontinuo y entre 1 – 4 días para uno continuo. Se invita al lector a revisar los pasajes de este trabajo de título, que cuenta con una detallada base teórica de todos los aspectos relevantes. Desde el proceso de extracción de los lodos y aquellos aspectos técnicos del secado, hasta llegar a los resultados y las conclusiones pertinentes.
The energy produced by the Sun’s light, turns out to be one of the most renewable natural resources throughout our country. Therefore, the use of it in different processes is increasingly more attractive because of its accessibility and sustainability. This energy can be exploited as thermal energy or photovoltaic. This work analyzes the technical feasibility of a dryer for septic sludge using the energy of the sun, which will be carried out in a wastewater treatment plant. In order to make this analysis, it is important to know all the variables that relate to the solar drying of mud, which leads to this work to be divided into three distinct sections. On the one hand, to know the behavior of solar radiation in the area of the plant throughout the year as well as in the months of study; On the other hand, to have the final temperature of air to be exposed to the radiation. And finally, to obtain the drying times of mud according to the previous variables. Throughout this work, the findings will be presented according to the months with the greatest radiation in the locality of the project, which is led by the month of January. Followed by those results that are related to the temperature increase of the air, where the temperatures will be exceeding the 60 [°C] and even more than 70 [°C], depending on the amount of air to circulate and the month. Finally, it is important to calculate the drying times for the septic sludge, which will depend on many factors. It will be able to see the drying curves for different flows of air and quantities of sludge. Depending on the type of dryer and the amount of product, the time will change between 2 and 7 [days] for a discontinuous dryer and between 1 and 4 [days] for one continuous. The reader is invited to review the passages and findings of this work, which has a detailed theoretical basis of all relevant aspects. From the process of removing the sludge and those technical aspects of drying, to the results and relevant conclusions.
