(54) INTEGRABLE SEPARATION DEVICE

I

The invention relates to the field of energetics, to, in particular, to semiaration. devices, pa3MemeHiHHM in a drum-separator with non-uniformly-loaded evaporation mirror. Known inside.division.separation

Devices containing a pierced hole shield, electric roller cen-agAtop, fenders

Shields, steam receiver shield, shield, and steam outlet pipe 1J-.

The disadvantage of the known device is the low separation efficiency, caused by secondary vapor moistening during

 percussion inlet of steam water supply system i .: nlichie. m foam.

It is also known to have an internal drum separating device comprising a fenced volume, in which a nutrient collector, a throttle body and a steam outlet 2 are located, formed by a pallet, end walls, guide plates and partitions.

The specified device TTG offers a high efficiency of steam separation due to a number of design flaws. In particular, the installation of partitions and guide sheets perpendicular to the pallet leads to cinnamon moistening of steam due to the shock entrance of the steam-and-water mixture into the fenced-in volume. The transverse placement of the feedwater collector relative to the longitudinal axis of the drum and the placement of the collector in the water volume of the drum do not provide a uniform supply of feedwater, quality, degassing, destruction and washing of the pipe,

In order to increase the efficiency of separation, in the proposed device, the partitions adjacent to the pallet are inclined to the latter at an obtuse angle, and the supply manifold is placed in the vapor portion of the enclosed volume. The baffles, guide plates and the collector are located along the axis of the drum in its tail section.

FIG. I shows the described drum separator, longitudinal section; in fig. 2 -

the same cross section.

In the drum separator,. placed the separation device, containing, formed by the pallet 2, end walls, 3 ,. guiding sheets 1. and partitions 5, a fenced volume, .fi, in the steam section of which are placed a feeding manifold 7, a throttle device 8 and a steam discharge pipe 9. Partitions 5 are adjacent to the node 2 at an obtuse angle. The partitions 5, the guide sheets 4 and the collector 7 are located along the axis of the drum I and are located in its tail section. The steam-water mixture is supplied to the fenced-in volume 6 through channels j formed by sheets 4 and partitions 5. Pallet 2 and,.: By walls 3

a hydraulic lock is formed 11. The pallet 2 is installed above the permissible water level 12 in the drum.

When steam is bubbled through the boiler water in the drum, the upper steam-water level 13 is set. The wet steam through the channels 10 enters the vapor portion of the fenced-in volume 6, where steam separation occurs due to inertial and gravitational forces. With the aid of the throttle device 8, the vapor load of the enclosed volume 6 is evenly distributed. On tray 2, the feed water moves in the direction of the hydraulic locks 11, through which it is discharged into the water volume of the drum, ensuring the constant removal of separated moisture from the tray and washing out the foam.

Installing the walls 5 obliquely to the pallet provides shock-free wet steam in the fenced-in volume 6, thereby eliminating the steam humidification. Placing the feedwater collector in the steam section of the enclosed volume 6 along the axis of the drum provides a uniform supply of water, effective washing and removal of the last and removed moisture and the enclosed volume 6.

The described intra-drum device improves separation efficiency.
