Abstract

The invention can be used in devices for the separation of steam-water mixture. The purpose of the invention, an increase in the separation efficiency, is achieved by the fact that a conical fairing 7 is installed in the diffuser nozzle 2 with a opening angle equal to the opening angle of the diffuser. The fairing 7 faces the separation chamber 4 with a base 8, the area of which is no more than 10% of the area of the outlet section of the diffuser pipe 2, which ensures equalization of the velocity field at the entrance to the package 5, uniform separation of the separating elements and reduction of the secondary entrainment of liquid. The size of the package 5 exceeding the outlet section of the diffuser pipe 2 creates a shadow zone for water from a liquid in the zone of its greatest concentration. Installation of additional conical shells 9 reducing the axial dimensions of the device. 1 z.p, f-ly, 1 ill. Yo

Description

The invention relates to a power system and can be used in various devices for separating a steam-water mixture.

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

The drawing shows a separator, a longitudinal section,

The horizontal steam separator 1 comprises a separation chamber 4 with a vertical stack of 5 separating elements installed between a coaxially arranged inlet diffuser with a predetermined opening angle and an outlet pipe 2 and 3. In the diffuser pipe 2, a conical fairing 7 is installed using ribs 6 with an opening angle equal to a predetermined opening angle of the diffuser pipe 2, facing the separation chamber 4 with its base 8, the area of which is not more than 10% of the output section of the diffuser pipe 2, and the package dimensions 5 separating elements exceed the size of the latter. In the diffuser pipe 2 can be installed one or more conical shells 9 with a taper angle of each subsequent one 8 ° more than the previous one.

The separator horizontal steam pipe works as follows.

The steam-water mixture passing through the steam line 1 in the inlet diffuser 2 loses speed, and there is a drop of moisture on its walls. The remaining fine moisture is separated in a package of 5 separating elements.

The installation of a conical fairing 7 with an opening angle equal to the opening angle of the diffuser nozzle 2 adjacent to the separation chamber 4 with its base, the area of which is not more than 10% of the output cross-sectional area of the diffuser nozzle 2, ensures the equalization of the velocity field at the inlet of the packet 5 and uniform load separating elements in the absence of an additional leveling device, and also 10 reduces the secondary entrainment of fluid. Exceeding the size of packet 5 of the separating elements of the outlet cross section of the diffuser pipe 2 creates a shadow zone for draining the liquid in the zone of its highest concentration. The installation of additional conical shells 9 reduces the axial dimensions of the device.

Claims (2)
