Description

f

The invention relates to a power system, namely to deaeration columns used for heating and thermal deaeration of water.

 invention - improving the quality of deaeration.

Fig. 1 shows a deaeration column, a longitudinal section; FIG. 2 shows the AA resolution of FIG. 1. FIG.

The deaeration column contains a bubbling plate 2 placed in the housing 1, adjacent to the vertical partition 3, which is lowered into the tray 4 with the formation of a water seal.

8 barging plate 2 are embedded vertical perforated sheets 5, with the ends adjacent to the body 1, and their upper edges are placed at the vertical septum 3. Sheets 5 form on the plate 2 compartments connected under the plate 2 by means of curved tubes 6. In addition, the column contains a distribution box. 7, overflow plate 8, made on the body of the nozzle 9 and 10 of the supply and removal of steam and the pipe 11 of the steam supply. The column is installed on the storage tank 12.

The column works as follows. .

Water to be deaerated through the nozzle

9 enters the water distribution plate 7, is poured onto the overflow plate 8 and then goes to the bubble plate 2. On the pressure plate 2, the water is heated to saturation temperature and sparged with steam fed to the housing 1.

through pipe I1. The deaerated water is discharged through the hydraulic lock formed by the vertical partition 3 lowered into the pan 4, into the tank 5, the battery 12. The steam passed through the liquid layer on the bubble plate 2 enters the space between the plates 2 and 8, where the preheating occurs and the coarse two 10 water erosion. Non-condensed steam and gases released during de-aeration are discharged from the housing 1 of the column through nozzle 10. Vertical perforated sheets 5, embedded in the bubbling plate 2, prevent the transfer of charged water from the inlet of the bubbling plate 2 to the outlet, and the treated water to the inlet, at the same time, the permeability of the sheets 5 to the free flow of water along the bubble plate 2 is prevented from doing so. Dp prevent the over-aerated water from being thrown from the entrance of the plate 2 to the top 4 sump

The 25 edges of the sheets 5 are placed above the partition 3. Thus, along the layer of liquid on the bubbling plate 2, the average concentration head is maintained, which is required in dp

30 efficient removal of aggressive gases. An increase in .Hydraulic load may result in skewing levels in the fluid layer on the plate 2.

35 is carried out by passing water through curved tubes 6, by means of which the compartments between the sheets 5 are connected. - / "
