METHOD AND APPARATUS FOR MIXED DELIVERY OF A MULTIPHASE FLOW, INVOLVING RECIPROCATING MOTION PERFORMED BY LIQUID IN TWO CHAMBERS Russian patent published in 2022 - IPC F17D1/14 F17D3/01 

FIELD: transport.

SUBSTANCE: apparatus for mixed delivery of a multiphase flow, involving reciprocating motion performed by liquid in two chambers, comprises a left-side tank (1), a right-side tank (2), a roller pump (3), a data reception and control system (4), a group of electromagnetic valves, a group of check valves, an intake collector (5) and an exhaust collector (6). The vacuum suction chamber and the compression injection chamber, formed alternately by the two tanks, act as the suction chamber and the injection chamber of a pump of for the mixed delivery of a multiphase flow. After separating gas from the liquid-gas mixture in the tank, the gas is compressed by the liquid and injected from the tank. The roller pump operates continuously in the pure fluid working conditions, thus eliminating the problem associated with the influence of a liquid with a high gas content on the roller pump. The present invention requires only the use of a conventional water pump to achieve mixed delivery of a multiphase flow, and even a conventional water pump can act as a vacuum pump and a compressor for pure gas and operate continuously. Also disclosed is a method for mixed delivery of a multiphase flow using the apparatus for the mixed delivery of a multiphase flow, involving reciprocating motion performed by liquid in two chambers.

EFFECT: ensured mixed delivery of a multiphase flow by means of the apparatus.
