Proračun trostepene ejektorske vakuum pumpe sa barometarskom kondezacijom

Abstract

Shown in this paper is the basic calculation and dimensioning of a three stage ejectors vacuum pump (steam-gas), condensers, pipes and ejector for achieving a vacuum of 0.995 bar, an absolute vacuum of 0.005bar for the evacuation of the resulting vapor in storage vessels of edible oil. Vapor at the entrance is a mixture of non-condensing gases (20%) and air (80%). Condensation is done in two stages with the vacuum suction of the remaining gasses via the ejector. It is necessary to achieve an inlet flow of usable fluids of 130 kg/h.
