Description

The invention relates to a power system, in particular to steam separation, and can be used in the construction of separators and separators-superheaters installed between the turbine stages.

A vertical separator is known, which contains a cylindrical body with separation blocks placed in it, each of which is equipped with a goat, a drainage trough and a drain stand. The separation units consist of guide vanes, louver bags and perforated sheets Ij.

In the well-known vertical separator, in the sector gaps between the separation blocks, there are entrance and output wedge-shaped boxes formed by inclined walls. In the design and development of separators, special design decisions are made to ensure equality of static pressures in different sections of the input and output wedge-shaped boxes, this is done in order to ensure a uniform velocity field along the height and width of the louver packages. Nevertheless, due to constructive and layout solutions, it is not possible to completely equalize the static pressure field both in width and in height of wedge-shaped boxes. The presence of the static pressure difference over the height of the wedge-shaped boxes leads to a static pressure over-ratio in each vertical stand and, in connection with this, to steam flow along each stand. The resulting steam currents prop up the drain of the separated liquid from the inclined drain channels, worsening the drainage conditions. If the load increases, this may lead to the complete cessation of discharge from the individual troughs. Violation of the normal drain of the separated liquid from the drain troughs into the rack leads to its accumulation inside the troughs, an increase in the level of the liquid in the troughs, the disruption of droplets with a level of steam to the removal of liquid through the holes of the perforated sheets. This causes a decrease in the efficiency and reliability of the separator, in addition, limit the ultimate load of the device. The disruption of the normal operation of the separator, caused by the above phenomena, is particularly significant in alternating loads.

The aim of the invention is to increase efficiency and reliability.

The goal is achieved by the fact that a vertical separator containing a cylindrical body with

The separation blocks placed in it, each of which is equipped with a visor, drain troughs and drain racks, are equipped with partitions installed in each drain

5 stand at its height, each of which is attached to the lower visor of the corresponding Rus separating blocks with the formation of autonomous drain channels.

The separator works as follows.

0 Wet steam enters the separator through the pipe 2, passes through the input wedge-shaped boxes 16, guide vanes 5, bags of louver G, perforated sheets 7 of the separation blocks 4, then through the output wedge-shaped boxes 16 and leaves the separator.through pipe 3. Separated from steam in bags of blinds C, the liquid flows into inclined drain troughs 8 and then comes

 into the vertical drain pillars 9 through the holes 10. From each trough of the separation blocks, the liquid is drained along an autonomous channel 13 formed inside the drain racks 9

5 peaks 11 and partitions 12. The lower end of each rack is wound under the level of the liquid in the drainage pocket 14, which provides a water seal that prevents the flow of fluid

0 from individual channels. .

The use of the invention improves the efficiency and reliability of the separator.
