1. A steam boiler liquid separator for a steam boiler through which steam flows vertically, comprising:
a pipe section;
a shaft in the pipe section;
a shaft segment holder;
a plurality of swirl vanes arranged about the shaft in the pipe section, wherein each swirl vane is connected to the pipe section, wherein the swirl vanes are shaped such that a rotational movement is imparted to a flow of steam through the pipe section in addition to a longitudinal movement through the pipe section;
wherein the pipe section has a plurality of pipe segments and the shaft has a plurality of shaft segments;
wherein each swirl vane is connected to a pipe segment and to a shaft segment to form a liquid separator segment;
wherein the shaft segments are attached positively and detachably to the shaft segment holder by a positive connection; and
wherein the shaft segments are held in position by the positive connection;
wherein a first closure element is connected to a first end face of the shaft segment holder and a second closure element is connected to a second end face of the shaft segment holder;
wherein the first and second closure elements have circular grooves with open sides facing the first and second end faces, respectively; and
wherein radially extending groove walls of the circular grooves engage axial ends of the shaft segments.
