Abstract

The invention relates to installations for the heating and degassing of water, for example, make-up water of heating networks. The invention makes it possible to improve the quality of degassing by effectively removing carbon dioxide. The installation contains a deaerator 1 and a calciner 2 placed in the same housing. Deaerator 1 has perforated plates along its length, two tanks (E) 12, 13 are located throughout the last two plates. Upper E 12 is connected by pipeline (TP) 14 with the bottom part of the calciner, and the bottom E 13 - TP 15 with its upper part. Bottom E 13 perforated. The decarbonizer is divided by annular partitions into separate chambers, to each of which steam is supplied tangentially through nozzles. E 13 communicated with the cavity of the nozzles (P) 20 and TP 21 with the space under the top plate of the deaerator. Water being processed through P 3 enters the deaerator and through the perforations of the plates merges into E 12, from where TP 14 enters the lower part of the calciner, rises in it and TP 15 enters E 13. As it moves in the calciner, the water is steamed and partially boils . The resulting vapor, together with the gases, is removed in E 13 and then through P 20 and TP 21 to the upper part of the deaerator and in P 5 the evaporation outlet. In the deaerator, the water is also treated with steam supplied through P 6. The combination of a centrifugal type calciner and a jet deaerator with repeated water treatment with steam provides effective removal of gases. 3 3. p. F-ly, 1 ill. c & (L

Description

The invention relates to a power system and 'industrial heat engineering and can be used for heating and deaeration of water supply, mainly of makeup water of heating networks.

The aim of the invention is to improve the quality of degassing by effectively removing carbon dioxide.

The drawing schematically shows the installation, General view.

The degassing installation comprises a deaerator 1 and a decarbonizer 2, placed in a housing with nozzles 3, 4, 5, respectively, for supplying and discharging water, for removing non-condensable gases and a nozzle 6 in communication with the heating steam supply line 7.

Perforated plates 8-11 are mounted on a deaerator 1 in tiers, two containers 12, 13 are placed between the last plates 10, 11. The upper container 12 is connected by a pipe 14 to the lower part of the carbonizer 2, and the lower container 13 by a pipe 15 d with its upper part, the poverty of the container 13 is perforated. An annular partition 16 can be installed in the decarbnisator 2, dividing it into separate chambers, and tangentially located nozzles 17 communicated through valve 18 with a heating steam supply line 7. On line 7, in front of the pipe 6, a pressure regulator 19 is installed. The lower container 13 by means of nozzles 20 and pipelines 21 communicates with the space under the upper plate 8 of the deaerator.

The installation works as follows.

The water to be degassed through the pipe 3 enters the upper plate 8 and then through its perforation to the next plates 9, 10, is discharged into the upper tank 12 and supplied through the pipeline 14 to the lower part of the decarbonizer 2. From the latter, through the pipe 15, water enters the lower capacity 13 and through the perforation in its bottom to the lower plate 11 and through the pipe 4 is discharged from the installation.

The steam supplied to the decarbonizer 2 through nozzles 17 heats the water and creates a rotational motion of the medium, as a result of which the pressure in the central part drops, and increases at the walls of the decarbonizer, while some of the water boils. The released steam along with the gases is discharged into the tank 13 and then through the nozzles 20 to the upper part of the deaerator. Multiple water treatment of vapors in separate chambers of the decarbonizer promotes intensive turbulization and mixing, which provides deep deaeration of water, including the removal of free carbon dioxide. The water coming from the decarbonizer into the tank 13 is superheated and when it expires through the holes in its bottom, it boils again and is washed with steam supplied from line 7 through the regulator 19 to the pipe 6.

Thus, the combination of a decarbonizer of a centrifugal type and a jet deaerator with multiple intensive treatment of water with steam, ensures the effective removal of all gases dissolved in water.
