Abstract

The aim of present study was to design an oil separator for the venting systems of gas turbine engines at consumption of gaseous medium 200 m3/h. In order to accomplish the objective, we applied separation gradient aerosol technologies, which consider all the forces and effects that influence deposition of the highly dispersed particles. A scientific base is substantiated for the intensification of gradient processes of the transfer of aerosol media in the boundary layers of multifunctional surfaces in the purification of dispersed polyphase flows for developing the technical devices that ensure an increase in energy saving and ecological improvement of power plants. We designed a section-by-section structural scheme and a three-dimensional model of the oil separator in finite elements for the calculation of hydrodynamics and separation. The calculations were conducted of the hydrodynamic situation and particle trajectory in the flow area of an oil separator. Using the calculated distribution of speed in the oil separator at G=100…200 m3/h, it was determined that velocity in the coagulation profile does not exceed 10 m/s. It was established according to the results of static pressure distribution for G=100, 200 m3/h that the pressure differential in the separation coagulators reaches 2.5…3.9 kPa, respectively. Results of the calculation at G=100…200 m3/h demonstrated that the summary pulsation effect from the deposition of highly dispersed particles amounts to 25.1 %. Based on the calculations, we designed the prototype of an oil separator and tested it experimentally on the test bench in the form of an open type wind tunnel. Coefficient of the total effectiveness of purification was determined, which reaches 99.9 %. The modernization of purifiers for capturing the aerosols in different systems of power plants is possible based on the separation gradient aerosol technologies. The studies conducted make it possible to develop in the future a range of separators for gas consumption from 20 to 2000 m3/h.
