Diseño de un biodigestor tipo manga para granja ubicada en la zona rural de Usme

Abstract

The lack of a comprehensive gas public service in the non-interconnected rural areas of the town of Usme in the city of Bogotá, has pushed its community to make use of little-conventional energy sources, such as liquefied petroleum gas and forest resources to its scope, which has contributed to the deterioration of its environment, and has had an economic negative impact due to the high costs in proportion to its economic capacity. This situation is reflected in the farm of Mary of the village los Soches in this area, a place with sufficient energy potential to develop the alternative solution represented by renewable energies, specifically in the case of gas, biodigesters, specifically the sleeve or tubular model, which is presented as the most appropriate for this situation, due to its low cost and the simplicity of its technology. Therefore, the main objective of the present project is to design a biodigester of this type, achieving it through the collection of primary and secondary information, the determination of gas demand and the biogas generation potential of the farm, the design of the biodigester, its ditch and its conduction network; the specification of its construction and operational requirements, and the cost-benefit analysis of the hypothetical implementation of the biodigester. It is concluded that the design of the biodigester was successful, since it: produces more than enough biogas to make up for the demand of the farm, and the energy potential of it make to foresee its production will be even higher; its investment cost does not exceed the current SMMLV, and its recovery period will be in the medium term and will generate income for the farm after this period.
