Cyclone separator for separation of a suitable - fluid flow, steam turbine plant with a cyclone separator and associated operating method

摘要

The present invention relates to a cyclone separator (1) to the phase separation of a suitable - fluid flow with a substantially about a central axis (m) rotationally symmetrical design, a cavity (3) surrounding housing (2), with at least one supply line (6) for the fluid stream, which are used for a substantially tangential to the inner side of the housing (11) directed inflow of the fluid flow is designed, and with at least one discharge line (24) for the separated gaseous portion of the fluid flow. Such a cyclone separator is to be improved to the effect that it is for heating the gaseous portion of the fluid flow and low requirements for material and space requirement represents. In addition, it should be as far as possible a uniform and homogenous flow distribution of the steam to be heated as it enters the heating phase be ensured. For this purpose is provided according to the invention that the cavity (3) of the central axis (m), starting in the radial direction, a flow-outlet space (16) with an essentially circular cross section and in the sequence mentioned, then a heating chamber (14), an intermediate space (15), a drier chamber (13) and an inlet chamber (12), each with a substantially circular cross section, wherein the inlet chamber (12) according to the outside through the housing (2) is limited, with the heating chamber (14) for heating the gaseous portion designed heating elements, in the drier chamber (13) at least one fine separator (28) and at least one associated condensate - collecting trough (32) are arranged, and wherein the at least one condensate - collecting trough (32) with at least one in the intermediate space (15) arranged condensate - discharge pipe (34) is connected, through which the, in the operating state, in the at least one fine separator (28) from the condensate forming cavity (3) is discharged.
