Abstract

Invention m. used in devices for the separation of vapor-liquid mixtures and improves the quality of separation under variable loads. In the vertical case 1 there are chambers 5 and 6 separated from each other by a transverse wall (PS) of the condensate collection and separation chamber, the latter of which is equipped with a spiral ribbed insert. A transverse funnel-shaped partition 8 with an opening 9, rigidly fastened to the spiral insert 7 and the housing 1, forms in the last chamber 10 a collection of steam. The spring-loaded valve II of the chamber 10 communicates with the opening 9. The central part of the PS is movably mounted along the axis of the body and has the shape of a hollow cone 12 with vertical edges 13. The cone 12 faces upward and is equipped with return springs 14. The peripheral part of the PS is made in the form of a ring 15 with - item 16, tightly fastened to the hull with the formation of a trough. The latter, when interacting with the edges 13, forms a water seal. When the pressure in chamber 6 is increased, the cone moves with edges to the side of ring 15, preventing the passage of steam with separated liquid. At the same time, the valve 11 is pressed from the partition 8, releasing steam through the opening 9 into the chamber 10, where it is finally dried. 1 il. i (L

The invention relates to a power system and can be used in devices for the separation of vapor-liquid mixtures. The aim of the invention is to improve the quality of separation under variable loads,

The drawing shows a longitudinal steam separator, a longitudinal section.

The steam separator contains a vertical case 1 with nozzles 2-4, respectively, supplying a steam-water mixture and removing steam and liquid, housed in case 1 of chamber 5 and 6 for condensate collection and separation, the last of which is equipped with a spiral silver insert 7. In case 1 there is also a transverse a funnel-shaped partition 8 with an opening 9, rigidly fastened to the spiral insert 7 and the housing 1 and forming in the latter a steam collection chamber 10 equipped with a sub-spring. The flap 11 interacting with the opening 9 of the partition 8. The chambers 5 and 6 are separated from one another by a transverse wall made of central and peripheral parts, the first of which is mounted movably along the axis of the housing 1 and has the shape of a hollow cone 12 with vertical edges 13 facing upwards and fitted with return springs 14. The peripheral part of the wall is made in the form of a ring 15 with flanging 16, tightly fastened to the housing 1 with the formation of a trough, which, when interacting with the edges 13, forms a cone 12 Hydrosis create.

: The steam separator works as follows.

; The steam line is tangentially injected through the inlet pipe 2 into the separation chamber 6, enters the spiral insert 7, where the main separation of the two-phase flow takes place, due to centrifugal forces, the liquid is thrown to the finned insert 7, flows down and through the hydraulic lock enters the collection chamber 5 condensate.

The river bulkhead 8 enters the vapor collection chamber 10 and is discharged through the discharge pipe 3 to the consumer. When the pressure in the separation chamber 6 is increased, the cone 12 moves with the edges 13 towards the ring 15, preventing the passage of steam from the screened liquid. At the same time, the valve 11 is pressed from the partition 8, releasing steam through the opening 9 into the steam collection chamber 10, where, upon expansion, its final drying occurs.

The implementation of a steam separator with a valve 11 and a transverse wall with a movable central part in the form of a cone 12 makes it possible to improve the quality of separation when operating at a variable pressure in chamber 6, especially when the steam-water mixture with a sharply varying pressure arrives.
