METHOD FOR AIRLIFT TRANSPORTATION OF TWO-PHASE AIR AND FLUID MEDIUM FLOW AND METHOD FOR ITS IMPLEMENTATION

摘要

A method for airlift transportation of two-phase air and fluid medium flow includes air supply to the inlet of the immersed into a fluid a liquid-lifting pipe, with lifting the two-phase medium via lifting pipe to the air separator, with separation of air from liquid. In the liquid-lifting pipe one makes forced traction for the two-phase medium through feeding compressed air, from compressor working from the electric mains. After lifting the medium to the air separator one switches off the electric current to the compressor from the main circuit, with switching on electric current form the hydro-unit, thus forming a closed cycle of self-circulation of two-phase medium without following loss of additional energy. An appliance for implementation of airlift transportation of the two-phase air and fluid flow comprises a liquid-lifting pipe, this is immersed to a vessel with a liquid, at its outlet is installed an air separator, and air-supply system, this at the inlet is connected to the compressed air source, and at the outlet - to the inlet of the liquid-lifting pipe. The liquid-lifting pipe at the inlet is equipped with at least one ejector and hydro-unit, and at the outlet - separator with hydro-unit and turbine unit. The liquid-lifting pipe at the whole length between the ejector and the air separator is divided with partitions to several independent parallel passes.
