Description

(54) VERTICAL SEPARATOR

1The invention relates to the field of power engineering, in particular to devices intended for steam sapping.

From the main auth. 1 494563 known vertical separator, containing a cylindrical body, divided by a transverse partition on. cavity wet and dry steam, located along the axis of the housing pipe outlet of the latter and placed in the annular channel between the housing and the pipe separation units installed radially and equipped with located in the sector gaps of the outlet and ducts, communicating through the holes in the partition with the dried steam l.

 The main disadvantage of the known separator is the presence of a constant high level of separated moisture in the drain troughs installed in a horizontal plane. At high flow rates in the separation units, there is a breakdown in the flow of moisture and the secondary settling of the separated steam. To ensure the required amount of steam, a reduction in flow rate is required.

wet steam in blocks, which therefore leads to a decrease in the performance of the separator.

The aim of the invention is to increase productivity.

To achieve this goal, drain troughs located under the separator units are set at an angle of 5-7. towards the horizontal towards the drain

0 rack.

In the cylindrical body 1 of the separator is made of pipe 2 drainage of dried steam and the pipe 3 for supplying wet steam. In the annular channel 4 between the housing 1 and the pipe 2 radially installed, separation blocks. The pilot guide vanes 6, louvers 7, perforated sheets 8. Under the separator blocks 5. installed at an angle of 5-7 ° to the horizontal

5 side of the drain stand 9 drain troughs 10, Drainage of dried steam from each unit 5 is carried out through a wedge-shaped outlet box 11, through the pie holes 12.

0 A transverse partition 13 separates the casing 1 on the cavity 14 and 15 of wet and dry steam. Wet steam enters the separator through the pipe 3, through the annular channel 4 is fed to the separation blocks 5i, the passage between the guide vanes 6, through the louvers 7, perforated sheets 8, through the wedge-shaped box 11, through the sector holes 12 enters the cavity 15 of the dried steam, and then into the pipe 2. the liquid separated into the louvers 7 flows into the drain troughs 10 and further into the drain rack 9. Installing the drain troughs under the separation blocks at an angle of 5-7 to the horizontal in the direction of the drain rack ensures reliable discharge of the separated liquid without sry GOVERNMENTAL phenomena - that allows thus increase syMZO steam is wet steam flow rate in the separation units and thereby improve performance of the separator, and at a given productivity and reduce the size motalloomkost separator. Formula and 3 units. Vertical separator according to the authors. No. 494563 differs from the fact that, in order to increase productivity, the discharge troughs located under the separation units are installed at an angle of 5-7 ° to the horizontal in the direction of the drainage rack.
