Description

(54) VERTICAL SEPARATOR

one

The invention relates to steam separation devices and can be used in heat and power engineering in steam superheater separator structures.

A vertical separator is known, comprising a cylindrical body with a pipe for supplying a steam-water mixture on a side surface, a steam exhaust pipe arranged along the housing axis and a radially mounted separation unit located in the annular channel between the latter and the housing, placed below the separation units and the annular water collector adjacent to the pipe, communicated with drain racks and outlet pipe 1.

The main disadvantage of such a separator is the low separation efficiency, especially at 100 ° C of the load of the separator due to unsatisfactory removal of the separat from the lower layer of separation units.

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

This goal is achieved by the fact that the separator is provided with an additional annular manifold and annular pan, the annular manifold is inclined at acute angles to the lateral branch pipe with a hole and lower walls, in the latter there is a recess in which the lower ends of the drain racks are placed, the annular pan is attached to the bottom wall, and the additional collector is installed at the level of the upper ends of the separation blocks.

FIG. 1 shows a separator, a general view; in fig. 2 - ring collector.

The vertical separator contains a cylindrical housing 1 with a nozzle 2 for supplying the steam-water mixture to the side surface. In case I, along its axis there is a pipe 3 for discharging steam and an annular channel 4 between pipe 3 and case 1; radially installed 15 separating units 5. Under separating units 5, an annular collector 6 of separated water is placed adjacent to pipe 3. The collector 6 is in communication with the drain pillars 7 and the outlet pipe 8. The annular collector 6 is made with

20 are inclined at acute angles to the lateral branch pipe 8 with a hole 9 and lower walls 10 and 11, respectively. In the bottom wall 11, a recess 12 is made, in which the bottom ends 13 of the drain pillars 7 are placed, with the formation of a water seal. An annular pan 14 with an opening 15 is attached to the bottom wall 11 under the recess 12. The annular pan 14 performs the function of thermal insulation. At the level of the upper ends of the separation units 5, an additional collector 16 is formed, formed, for example, by a vertical annular partition 17. The collector 16 is in communication with an opening 18 made in the body 1.

The steam-water mixture flows into the housing 1 through the pipe 2. Moisture released on the walls of the housing 1 above the separation blocks 5 collects in the collector 16 and is discharged from the housing 1 through the opening 18. Moist steam enters the separation blocks 5, is separated and separated through the pipe 3 assigned to the consumer. The water separated in blocks 5 is separated by means of discharge racks 7 enters the annular collector 6. Separated from collector 6 by inclined walls 10 and AND, forming a confuser, is dispersed before its subsequent discharge from the housing 1 through nozzle 8. The released secondary steam through the hole 9 in the side wall 10 is retracted into the steam space of the housing 1. The ring pan 14 protects the separator entering the collector 6 from the racks 7 from the effect of dried steam, eliminating vaporization and movement of steam towards the flow of the separated separator.

The supply of the proposed separator additional annular manifold and

ring tray provides reliable removal of the separat from the body, eliminates the secondary boiling up of condensate, which increases the efficiency of steam separation.
