Description

one

The invention relates to devices for removing carbonated air from feedwater and can be used in thermal power plants and heating boilers.

Deaerators are known, for example, to remove carbonated air from feedwater, comprising a housing with air and condensate discharge nozzles and a feedwater inlet above which is a perforated sheet for sparging feedwater.

A disadvantage of the known devices is the impossibility of uniform air removal.

For the purpose of uniform air removal in the proposed deaerator, a plate with a conical calibrated orifice is placed in the nozzle for exhausting air.

The drawing shows the proposed deaerator. general form.

It contains a housing 1 with a nozzle 2 for 2

1 da air, pipe 3 for condensate and fitting 4 for the supply of feed water. Above fitting 4 in housing 1 there is a perforated sheet 5 for providing uniform directional movement of water, and in front of the nozzle 3 there is an inclined screen 6 Ex1 forming a settling chamber 7. The upper end of the screen 6 is located above the nozzle 3.

The deaerator works as follows.

Feeders {and water enters the hull, through

fitting 4 for the perforated sheet 5. The feed water, after passing through the holes of the sheet 5, is evenly distributed over its entire area. The air released from the water creates backwater, necessary

dp maintain a certain water level. The magnitude of the backpressure is regulated by uniformly removing air through the calibrated cone hole 8 in the plate 9. When the amount of carbonated air is released from

water, increased by 71Т1О under the action of increased pressure will decrease. the level of water, and non-smelt 10, fixed on the brush 11 with the possibility of movement in guide 12, will go down. Passing section between control valve 3

and the tapered hole 8 is enlarged, which leads to the release of excess air. The desired water level is restored.
