Description

(54) THERMAL DEAERATOR

one

The invention relates to thermal deaeration of water and can be used to prepare the feed and make-up water of boiler units, heating networks, and especially determine the origin of water.

Thermal deaerators are known to contain a storage tank with a barbo device and a shortened jet column ij 2.J.

in the tank-battery, the removal of the smallest gas bubbles from the water and the decomposition of bicarbonates, carbonates and unstable organic substances take place.

The latter requires a certain time and, consequently, the duration of the stay of water in the deaerator, or its volume plays a large role, to ensure deep water degassing.

The placement of the bubbling device in the storage tank intensifies the degassing process. At the initial section of the bubbler, additional water is heated to

saturation temperature, while the main degassing process takes place on the rest of the bubbling device at the rate of saturation.

Heating and deaerating of the priests in a column takes place by direct contact with the steam. At the same time, all the steam is condensed in the de-aere of the air and mixed with deaerated water. Steam consumption, determined by the performance of the de-aerator, reaches large values by heating the water. Receiving such an amount of steam and rubbing its condensate is costly. When de-aerating sea water and brackish water during desalination, direct contact of water with steam leads to loss of steam distillate.

Partially, these drawbacks are described in another well-known deaerator, which is closest to the invention by its technical essence and the achievable result.
