Adaptive centrifuge vibration damping module for biofuel production

Abstract

The present study considers the problem of obtaining promising renewable energy sources, in particular biofuel. Biomass is the main fuel for green energy accounting for two-thirds of renewable energy. Industry further development depends on improvement of used equipment and technologies. Biofuel usually contains significant amounts of harmful impurities that need to be isolated. The paper deals with the problems of centrifuge operation for the biofuel production. In particular, the most significant operation problem is the residual rotor imbalance which causes torsional oscillations that negatively affect the biodiesel production process and centrifuge reliability. A new technology for damping torsional vibrations of centrifugal device rotating system is described as well as adaptive module device for its implementation is developed. The module main feature is vibrations adaptive level of the rotor elements interaction with external environment. Computer simulation of the module operation process in ANSYS Fluent program was carried out. Data on the module efficiency depending on various factors in the dynamics of its work are obtained. The most effective device configuration is determined.
