Abstract
The invention relates to a double-flow screw spindle machine for drive generation by multiphase mixtures or for the delivery of multiphase mixtures, comprising at least two separate inlet chambers (11, 12) and an outlet chamber (20), and a separator (30), situated upstream of the inlet chambers (11, 12), for separating liquid phase and gas phase. The object of the present invention is to provide a dual-flow screw spindle machine which is easily adaptable to changed process conditions. This object is achieved by virtue of the fact that both inlet chambers (11, 12) are connected to the separator (30) by separate lines (31, 32; 33) for the gas phase and the liquid phase.
Claims9
A double-flow screw spindle machine for multiphase mixtures, comprising:
- a plurality of screw spindle pairs arranged in a housing such that gaps between screw spindles, and gaps between the screw spindles and the housing, are sealable with liquid phase;
- at least two separate inlet chambers to the plurality of screw spindle pairs;
- an outlet chamber;
- a separator situated upstream of the at least two separate inlet chambers for separating liquid phase and gas phase;
- one or more first connecting lines which are configured to selectively pass the separated gas phase when the separator contains a multiphase mixture;
- and
- one or more second connecting lines which are configured to selectively pass the separated liquid phase when the separator contains a multiphase mixture, the one or more second connecting lines being separate from the one or more first connecting lines,
- wherein the at least two separate inlet chambers are connected to the separator by the one or more first connecting lines and, separately, by the one or more second connecting lines, and
- wherein the separate connection of the at least two separate inlet chambers to the separator by the one or more second connecting lines enables delivery of liquid phase that lubricates and seals at least one screw spindle pair when the separator contains a multiphase mixture.
