Diseño de un biodigestor anaerobio para la generación de biogás a partir de los desechos orgánicos generados en la Hacienda Rocon

Abstract

In this paper titling a digester floating bell, in order to obtain biogas from organic waste generated by cattle Hacienda Rocon, located in community of San Miguel de Guaructus, in the parish The Matrix, Canton was designed Chambo, Chimborazo province. manure sampling was performed 15 cows in production for three days with an average manure production is 7.00 kg per each; therefore considering the study population of 61 cows in production have a load of 427 kg daily manure, to meet the production of biogas a home digester in which the residence time was 36 days was determined was built, the amount of biogas generated was 0.63 L / day, with an average temperature of 16 ° c; This is performed as a 5L flask which was used 3/4 its ie 3.75 kg of manure and water dilution; same that was located under cover being monitored for 45 days, the flame test was performed to confirm the presence of biogas, an average of 0.34 m3 / kg fed solids was obtained. After obtaining the experimental data, we proceeded with the design calculations for the same digester having a height of 9.62 m, 6.64 m of which will be underground and 2.72 m remain on the surface; It has a radius of 1.45m, a shits 655.2 kg / day and a biogas production of 15.36 m3. It is concluded that once the data obtained digester plans the same as minimize the impacts of organic waste and the implementation of the digester is recommended at the bottom of the milking parlor of the farm were developed.
