Description

Par K1 / Shenny

(P

The invention relates to heat and power engineering, namely to devices for steam separation, and can be used to create steam power plants with saturated steam turbines both in separate separator structures and as part of a separator / superheater incorporated in the steam path turbines between high and low pressure cylinders.

A steam separator is known, containing a vertical cylindrical body with a radially installed, in the upper part of the body, a supply pipe 15 for the gas-vapor mixture, a lid, a central steam exhaust pipe, and separation blocks S13 placed around the latter.

A disadvantage of the known separator 20 is the low separation efficiency due to the uneven distribution of the wet steam in the separation units when the central pipe is rounded. 25

The purpose of the invention is to increase the separation efficiency.

This goal is achieved by the fact that the steam separator, containing a vertical cylindrical body with a radially installed in the upper part of the body a nozzle for supplying the vapor-gas mixture, a lid, a central, jt steam discharge pipe, placed by the BOKDvr last Russian separation blocks, is equipped with a perforated shell, adjacent to the lid and covering the pipe, the

The shell current facing the nozzle is open.

shell, general view.

The steam separator contains a vertical cylindrical housing 1 with a radially installed inlet pipe in the upper part of the housing 1 for supplying a vapor-gas mixture and a conical collar 3. In the housing 1 there is a central steam exhaust pipe 4, and around the latter separation blocks 5 are located. 4 perforated shell 6. At the same time, the section of the shell facing the nozzle 2 is open, and the width of the open part depends on the diameter of the nozzle 2.

The steam separator works as follows ..

The gas-vapor mixture is supplied to the separator through the pipe 2 and the pipe f is distributed over the separation blocks 5. At the entrance to the housing 1, the vapor-gas mixture is wet. steam enters the perforated shell 6, which dampens the dynamic effect of the wet steam flow on the separation blocks. 5, located on the side opposite to the nozzle 2, and distributes the flow of wet steam evenly across the separation units, which increases the separation efficiency. The grinding of separate drops on the side 6 also reduces the erosive wear of the structural elements of the separator.
