Abstract
The invention pertains to the field of fluidics and jet technology. The essence of the invention: is a vacuum-producing device composed of a liquid-gas jet apparatus, a separator and a pump, is furnished with a jet pump, so that the gas inlet of the liquid-gas jet apparatus is connected to a pipeline for discharge of vapors from a rectification column, the liquid inlet of the liquid-gas jet apparatus is connected to the discharge side of the pump, the outlet of the liquid-gas jet apparatus is connected to the separator, the passive medium inlet of the jet pump is connected to the separator, the outlet of the jet pump is connected to the suction side of the pump, the active nozzle of the jet pump is connected to a pipeline for export of a liquid fraction from the rectification column. This vacuum system results in increased efficiency and productivity.
