Abstract

The invention makes it possible to increase productivity and increase the reliability of the deaerator. On the jet tray 2 there are nozzles 9c, - sprays 10 and a partition 11, which divide the superheated liquid distribution chamber 5 into two compartments connected by a hydraulic lock 12. At high flow rates of superheated water and the steam generated by it, the chamber is filled with superheated liquid, which is injected through the nozzle into the inkjet compartment 3. This embodiment makes it possible to further deaerate the flow of superheated liquid and evenly distribute the heating medium in the compartment. 1 il.

Description

The invention relates to power engineering, industrial heat technology and can be used to heat and deaerate water under conditions of use as a heating medium of a superheated liquid.

The purpose of the invention is to increase the productivity and increase the reliability of the deaerator.

The drawing shows a deaerator, a longitudinal section.

The deaerator contains water distribution chamber 1 with jet tray 2, jet compartment 3, bubbling sheet 4, superheated liquid distribution chamber 5 with a water-splitting device 6, and 7 boiling water overheating water compartment 8 with steam trap valve 8. The deaerator is equipped with 9 branch pipes with distributors 10. The chamber 5 of the distribution of the superheated liquid is divided by a partition 11 into two compartments connected to each other by a hydraulic lock, 12. The deaerator works as follows.

The cold, deaerated water is fed into the water distribution. The oligo chamber 1 and through the jet plate 2 enters the inkjet compartment 3 and undergoes steam treatment in this compartment during exhaust of the steam diverter valve 8 and the bubbling sheet 4. The heating medium (overheated water) is fed into the superheated fluid distribution chamber 5 , is subjected to angshogy crushing and enters compartment 7 of boiling, where it is separated into steam and water. The formed steam at low loads is supplied under the bubbling sheet 4. With increasing load, the steam-bleed valve 8 is activated. Then the steam is condensed on the jets, and the non-condensed vapor-gas mixture is retracted into the line. With insignificant loads in the chamber 5 of the distribution of the overheated liquid, the level of the liquid is ensured, at which it is prevented from entering the nozzles 9. Steam access to

In these modes, the nozzles are closed by a hydraulic lock 12. At high flow rates of superheated water and the steam generated by it, corresponding to the pressure drop on the bubble sheet close to the maximum allowed, chamber 5 all the way fills up with superheated liquid, and the last is injected into the jet compartment 3 through nozzles 3. This is accomplished both by the pressure of the superheated water (in the line) and by the dilution created by the jet compartment.

The supply of a heating medium to the jet compartment improves the quality of water treatment, both by additional deaeration of the flow of superheated liquid and by improving the conditions for the removal of gases from the jet compartment. The even distribution of the heating medium in the jet compartment contributes to the deaerator performance, eliminating the occurrence of water hammer, increasing the reliability and durability of its operation.
