Diseño de un biodigestor para la producción de biogás generado por las excretas de ganado vacuno, en el Criadero “Jersey Chugllin".

Abstract

The current investigation designed a bio digester to get biogas from using beef cattle organic waste generated at the Jersey Chugllin hatchery located in Canton Chambo, Chimborazo province, with which it seeks to reduce pollution by the waste. Through the experimental method a sample of 6 cows manure was collected during 5 consecutive days obtaining an average of 7.5 kg per day, two practical 20L digesters were built using two cans, pipes and valves, the first one was named experimental biodigester 1 it remained at room temperature and the second one was named experimental biodigester 2 which was located in an improved thermal conditions area, both of them were monitored during the time dwell of substrate in which temperature data was collected, a tube and flame test were carried out during the biogas generation process. Design formulas for a tubular biodigester were applied to project the experimental results for a total of 15 head of cattle and for obtaining overall performance by which the experimental biodigester 2 was chosen with the following parameters: retention time 38 days, 224 kg / d of daily load , 11.34 m3 of biodigester total volume , 1.27m of diameter, 8.95 m. of length Concluding that the production of methane gas is 2.83 m3 per day with what would be achieved by supplying 45% of the total value needed to cover the hatchery activities in which liquefied petroleum gas (LPG). It is recommended to implement the biodigester for minimizing the negative impacts caused by organic waste from cattle being these that serve as raw material used to produce products such as biogas and boil. In addition, studies must be carried out for this system was implemented, according to the climatic zones of this country.
