Diseño y simulación térmica de un biodigestor con capacidad de 100 l/día para calentamiento de agua sanitaria

Abstract

The purpose of this technological proposal is the thermal analysis of a biodigester capable of heating 100 l of sanitary water per day in the Píntag sector. The methodology used was the experimental design based on data obtained after the investigation and using the ANSYS Fluent CFD simulation software. Based on the analytical results, it was obtained that the amount of biogas that can be generated in the proposed design of the biodigester is 4.0375 m3, in the simulation, thanks to solar radiation, the biodigester can reach externally in the winter and summer seasons a temperature of 35 ºC and 37 ºC respectively, with these data obtained a second simulation was carried out where the temperature inside the bag was obtained where it reaches an approximate temperature of 35 ºC, which, meets to carry out the mesophilic fermentation process, making possible the operation of the biodigester in the sector, the cost of manufacturing the biodigester can be approximately $ 547, being an affordable price for people in the sector.
