Study on Optimal Circulation Dynamic System and Feasibility Analysis for a Solar Biogas Digester

Abstract:

According to biogas digester heated by circulation of water heated by solar cell, three modes of hot water circulation dynamic system (one-stage cycle, multi-stage cycle, and continuous cycle) were proposed to reduce operating costs and optimize the operation. The results obtained showed that multi-stage cycle had a clear advantage in improving operating efficiency, the heat transfer of which was 41.57KJ, much higher than 7.21KJ of one-stage cycle and 2.20KJ of continuous cycle. A model was built to simulate the overall process of heat dissipation in comparison with what was obtained from the conventional experiments. Both the simulation and the experimental measurement data showed that multi-stage circulation dynamic system operated well.
