STUDY ON THE FILTRATION PERFORMANCE OF RGO FILTER MATERIAL FOR OIL MIST PARTICLES RELEASED FROM TURBINE OIL

ABSTRACT
How to effectively filter the multi particle, oily and viscous particles generated by the release of turbine oil is one of the urgent problems to be solved. This article studies the filtration performance of reduced graphene oxide (rGO) filter materials for PM10, PM2.5, and PM1.0 released from turbine oil, and analyzes the effects of filtration velocity and particle viscosity on filtration efficiency and resistance. The results indicate that the pollution generated by the release of turbine oil is mainly fine particles, with a cumulative proportion of particles
