A device for implementing the method comprises a double-walled housing, a water distribution tray. An air inlet is made in the upper part between the walls, and in the upper part of the casing there is an air outlet for venting the boiler furnace. In the gap between the walls, a tray with a perforated bottom and air-passing heat-exchange pipes is installed, the air from which is directed into the housing. Part of the water flow is sprayed into the housing by nozzles on the sprinkler. Water is also directed from nozzles to nozzles. Part of the water flow is directed to heating greenhouses, fish hatcheries, and batteries. 2 s.p. f-ly, 3 ill.

Description

The invention relates to a power system, in particular to cooling the circulating water of a steam turbine condenser, with closed water supply systems.

The purpose of the invention is to recover the heat of the exhaust air.

This goal is achieved by the fact that in the method of cooling the circulating water, the steam turbine condenser consists in dividing the water stream into two parts, one of which is sent to irrigation heat exchangers, and the other to the trays located above the latter, while the second part of the stream is cooled simultaneously with aeration and in a steady stream with air, the second part of the water stream is cooled between the walls of the body, and heated moist air is collected in the upper part of the body and sent to the consumer, for example Imer, in the furnace of a steam boiler.

This goal is also achieved by the fact that in the device for implementing the method of cooling water, comprising a housing, a piping system for supplying and discharging water, means for spraying water and aeration, water collecting containers, a distribution tray in the upper part, in the upper part of the space between the walls an air inlet is made, additional means are installed in the gap between the walls for spraying water with perforated bottoms, and an air outlet is made in the upper part of the housing a vent for venting the consumer, for example, to a boiler furnace.

Figure 1 shows the proposed device, a General view; figure 2 is an additional means for spraying water; on fig.Z. - section aa in figure 2.

contains a housing 1 with double walls 2,3 and a blind roof 4. In the housing 1, a water distribution tray 5 is installed, into which water from a condenser 7 of a steam turbine 8 is supplied through a pipe 6. An air outlet 9 is made between the walls 2,3 in the upper part of the device and an air outlet 10 is made in the upper part of the housing 1 for venting warm moist air to the consumer, for example, into the furnace 11 of the boiler. In the gap between walls 2,3, additional means are installed for spraying water in the form of trays 12 with perforated bottoms 13 and air passage heat exchangers 14,15 with openings 16 for the entry of water, which flows through the walls in the form of a film, and openings 17 through which water is sprayed. An annular container 18 for collecting water is placed around the perimeter of the device between the walls 2,3. A part of the water flow from the pipeline 6 through the pipeline 19 is fed into the housing 1, enters the spray nozzles 20 and sprinklers 21. From the tank 18, water is supplied to the distribution pipes 22 connected to the nozzles 20. Another part of the water flow through the pipeline 23 is supplied for heating the housing 1 of consumers, for example, greenhouses 24, fish hatchets 25, into heating batteries 26. At the bottom of housing 1, an air inlet window 27 with an adjustable shutter 28 is made. An exhaust pipe 29 is passed through the bottom of the container 18. At the bottom of Pusa 1 is inclined pan 30, drainage basin 31. Sprinklers 21 are installed on the grid 32. The casing 1 may be provided additional heat-insulating walls 33, 34. The cooled water is discharged to the condenser 7 via conduit 35.

A device for implementing the method of cooling water works as follows.

The exhaust steam of steam condensing turbines enters the condenser 7, where it is cooled and condensed by circulating water, heated to about 30 ° C at the outlet of the condenser, after which part of the water stream passes through pipeline b through the pipeline to 19 to the system of spray nozzles 20 where it is cooled by the air flow in countercurrent sprinklers 21 located in the lower part of the housing on the grate 32. The second part of the water flow through the pipe 23 flows from the bottom up to the heated hatcheries 25 and further through the heater 26 batteries. where it cools, to about 25 ° C and fills the distribution tray

5. A third of the stream of water with a temperature of 30 ° C through line b enters the tray 5: in which it mixes with the previous stream and, overflowing over the edges of the tray 5,

spreads in the form of a film on the inner surface of the walls 2 of the roof 4, from which it enters the distribution tray 12. The tray 12 is at the same time a hydraulic shutter preventing entry

air and the enclosed volume of the housing 1. Water, the passage through this tray 12, in the form of streams enters the irrigated volume enclosed between the walls 2,3. Air passage heat exchangers 14.15 can be

5 different in height and configuration and work on the principle of a heat exchanger. The heat and mass transfer between air and water both in the irrigated volume and in the pipes 14.15 proceeds in the process of deaeration. Water from the irrigated volume enters the annular tank 18, from where it passes to the distribution pipes 22. The air from the irrigated volume passes through the air passage 29 and enters the lower part of the housing 1 under the wipers 21, where it is mixed with atmospheric air, the amount of which is regulated by an automatic valve 28 Since in the closed volume of the housing 1 is created

0 vacuum using the air duct connecting the hole 10 with the furnace 11 of the steam boiler, then the air from the lower part of the housing 1 moves upward through the sprinklers 21, where it is heated. Heated air

5 passes through the culverts of the gratings 32. Water after irrigators 21 okh- / Gadzhitsya to a temperature of 18-20 ° C and enters the pool 31, from where it is sent to the condenser 7. The device can work

0 autonomously, as in combination with existing cooling towers, a large part of the circulating water is taken up to 90%, while the heat load on the cooling tower is reduced. In addition, the circulatory

The system is closed even in an emergency. When working together with the cooling tower, no additional costs are required, since a haft of chimney is used, which creates a vacuum in the furnace 11 of the steam boiler.
