Abstract

An OUTER CENTRIFUGAL STEAM SEPARATOR, containing a vertical cylindrical body with tangential pipes for supplying steam-water mixture, pipes for removing steam and water, placed in the body of a coarse and fine separation stage, the last of which has a spherical section of the housing with an overflow pipe, characterized in that, in order to increase separation efficiency and productivity, the catchment chamber is additionally connected The pipe is connected to a coarse separation stage in front of a fine-separation cTyneiiH nozzle, with the end of the pipe connected to the stage tangentially and oppositely to the steam-water mixture inlets.

Description

The invention relates to power engineering, and specifically to devices for the separation of betting.

A remote centrifugal centfi .iiop pair is known, comprising a housing with a tanner; 1Y1y. mixes, pipes for removal of water and nara (1 |.

The disadvantage of such a separator is the low separation efficiency.

The closest to the invention in its technical essence and the effect achieved is an external centrifugal separator containing a vertical cylindrical body with tangential strains for supplying the steam-water mixture, steam and water branch pipes located in the body of a coarse and fine separation, located in the spherical section of the hull, a catchment chamber connected to the spherical section of the cornea by the overflow pipe 2.

However, for a known separator, the separation efficiency is not high enough due to the disruption of the liquid film from the housing wall in the coarse separation stage and its entrainment by steam flow, and its performance is limited.

The aim of the invention is to increase the separation efficiency and productivity.

This goal is achieved by the fact that in a remote centrifugal steam separator containing a vertical cylindrical body with tangential nozzles. They supply steam-water mixture, steam and water exhaust nozzles placed in the case of coarse and fine separation, the latter of which has a nozzle device placed in the spherical section of the housing, the catchment chamber connected to the spherical section of the housing by the overflow pipe, the catchment chamber is additionally connected by a pipe to the coarse separation stage in front of the nozzles The device is equipped with a fine separation stage, with the end of the pipe connected to the stage tangentially and opposite to the nozzles for supplying the steam-water mixture.

FIG. 1 shows an external centrifugal separator, general view; in fig. 2 shows section A-A in FIG. one.

Remote centrifugal steam separator contains a vertical cylindrical

housing 1 with tangential nozzles

2 supply of steam-water mixture, branch pipes

3 and 4 removal of steam and water, respectively. In case 1, stages 5 and 6 of coarse and fine separation are exchanged. The stage 6 of fine separation has a nozzle device 7 placed in the spherical section 8. In the lower part of the housing 1 a catchment chamber 9 is placed, connected by an overflow pipe 10 with a spherical section 8. The stage 5 of coarse separation stitches branch pipes 2 for supplying the steam mixture, pipe 11 connected to a water collection chamber 9.

End of 12 pipe and located in front of

5 by a nozzle apparatus 7 stages 6 fine separation and connected to the stage 5 coarse separation tangentially and oppositely to the nozzles 2. The pipe 11 can be connected to the surge tank 13. The feed water from the pipeline is carried out through the pipe 14.

The steam duct is supplied to the mixture in the housing 1 through tangential nozzles 2 in the a-upen 5 coarse separation, where due to the centrifugal effect, water and steam are divided. When the mixture is twisted, a water film 15 is formed, which, as the separator load increases, is destroyed by the steam flow and, maintaining movement around the circumference, rises upward, where it is caught by the tangential end 12

0 pipe 11 and is discharged into the catchment chamber 9 (through surge tank 13). The partially drained steam further rises and enters the nozzle device 7 of the stage 6 of fine separation. The water separated in stage 6 is collected in the spherical area 8 and discharged from it into chamber 9 through the overflow pipe 10. The drained steam is discharged from the separator through the pipe 3.

Coarse separation connection

with a catchment chamber, an additional tube, the end of which is connected to the stage tangentially and opposite to the nozzles for supplying the steam-water mixture, allows

5 to withdraw a film of water rising upward on the body and destroying with increasing separator load into the catchment chamber and excluding the secondary moistening of steam, which increases the separation efficiency and, while ensuring high dryness

0 a pair allows to increase the capacity of the separator 1.5-2 times.
