The invention relates to the field of energy and can be used in circulating water systems thermal and nuclear power plants with cooling pond.

There is a method of cooling the circulating water in the pond-cooler (see and.with. The USSR 800308, MKI E 03 IN 1/00, BI 4, 1981), including the discharge of warm water in the cooling pond, the cooling and intake chilled water and more efficient use of evaporation of the cooling pond by raising the bottom layers of the water supply part of the discharged warm water in the bottom part in the area of water intake.

The disadvantage of this method is incomplete the effect of heat and mass transfer of a mirror surface of a pond-cooler and the cold air due to the presence of only translational motion of the cooled water.

There is a method of cooling the circulating water in the pond-cooler (see RF patent 2162919, IPC 7 E 03 B 1/00, 7/04, 05 B 1/34, BI 4, 2001), including resetting the core h is their curvilinear spiral guides installed on the pipeline at an angle of 45oto the course of transit, placed at the level of the water surface in the pond, cooling water, more efficient use of evaporation of the cooling pond by raising the bottom layers of the water supply part of the discharged warm water in the bottom part in the area of the water intake and water intake is carried out by selective water intake.

The disadvantage of this method is the lack of heat transfer due to incomplete use of the contact between the water surface of the pond-andalites and cold atmospheric air.

The technical task to be solved by the invention, is to reduce the temperature of water to be abstracted to theoretically possible value and a significant increase in the efficiency of evaporation of the cooling pond by use of heat exchange cooled water and atmospheric air, generated by the action of pulsators, made of curved bimetallic plates, the opposite ends of which form an angle of 90othat number not less than four, placed in the chambers provided on the elastic sleeve, and the chamber communicates with the atmosphere by means of struts with a bell on their con-way cooling water circulation in the pond-cooler, including resetting the main part of the warm water in the cooling pond, the swirling flow of waste water through an expanding nozzle with an inner curved spiral guides installed on the pipeline at an angle of 45oto the course of transit, placed at the level of the water surface in the pond, cooling water, more efficient use of evaporation of the cooling pond by raising the bottom layers of the water supply part of the discharged warm water in the bottom part in the area of the water intake and water intake is carried out by selective water intake, at the point of discharge of the main part of warm water in the cooling pond heat exchange between cooling water and atmospheric air is realized by the action of pulsators, made of curved bimetallic plates, the opposite ends of which form an angle of 90othat number not less than four, placed in the chambers provided on the elastic sleeve, and the chamber communicates with the atmosphere by means of struts with bells on their end, and the socket is made with the inner curved spiral grooves.

In Fig. 1 depicts the implementation of the proposed method, Fig. 2 - scheme of the pulsator, made from from anime spiral guides.

Warm water through the pipeline 1 is the area of the spillway of the pond-cooler 2, the cooled water from the zone of the catchment is drained by a pipe 3 at fossil or nuclear power plants. Part of the discharged warm water is fed via line 4 into the bottom part in the area of water intake. When this occurs, the mixing of warm and cold water. Reset the main part of the flow of cooling water is carried through the pipeline 5 on which you installed the expanding nozzle 6 with the inner curved spiral guides 7, oriented at 45oto transit flow 8 in their current, is connected by a flexible insert 9 to the pipe 5. The withdrawal of water from the cooling pond 2 is carried out by means of selective withdrawal 10 cold water. The pipe 5 pipe 11 is attached to the camera 12 provided on the elastic sleeve 13. The camera 12 is installed pulsators 14 made of curved bimetallic plates 15, 16, 17 and 18 not less than four. The opposite ends of the curved bimetallic plates form an angle of 90oplates were planted on the axis 19. The camera 12 through the pipe 11 and the pipe 5 is communicated with the atmosphere by means of struts 20 with the socket 21 with the inner curved vindoo is I as follows.

Warm water through the pipeline 1 is in the catchment area of the pond-cooler 2, the cooled water from the zone of the catchment is drained by a pipe 3 at fossil or nuclear power plants. Part of the discharged warm water is fed via line 4 into the bottom part in the area of water intake. When this occurs, the mixing of warm and cold water. As a result, the density of water decreases, and bottom water rises to the surface. The main part of the stream of water is discharged through the pipeline 5 on which you installed the expanding nozzle 6 with the inner curved screw guide, oriented at 45oto current transit stream 8, is connected by a flexible insert 9 to the pipe 5 at the level of the water surface in the pond. When passing through an expanding nozzle 6 with the inner curved spiral guides 7, the flow of warm water is twisted and on the surface of a pond-cooler 2 are formed of an expanding wave, magnifying mirror surface and the contact area of water and cold atmospheric air up to 1.5 times. Accommodation expanding nozzles 6 at an angle of 45oto the course of transit creates favorable conditions for the interaction of waves with warm spasib, is kasiva resistance to the flow of transit jets, intensely more mixed, creating standing waves, which effectively probing with cold ambient air. Flexible insert 9 extending between the nozzles 6 and pipe 5, and an elastic sleeve 13 with the camera 12, is connected by branch pipes 11 to the pipe 5, allows the extending nozzles 6 is constantly on the crest of a wave, as well as provide for the creation of waves in the boundary layer, which also strengthens the process of heat exchange. Pulsators 14 made of curved bimetallic plates 15, 16, 17 and 18, mounted on the axle 19 and placed in the chamber 12 provided with strut 20 with the atmosphere due to the difference in temperature between the warm water discharged into the cooling pond 2, the cold river water and cold atmospheric air, pulsating and suck through the riser 20 cold atmospheric air, which is mixed with warm discharged water, and spun in a curved spiral grooves located on the inner surface of the bell, dispersed in a water flow. Suction of cold atmospheric air is promoted by nozzles 6, having on the inner surface crevice nozzles 6 and pulsators 14 forms a dam at the inlet of cold river water, the discharge of warm water extending through the nozzle 6 toward the flow of the river further contributes to the rise in water level and a waterfall, dramatically increases the heat transfer in the pond-the cooler 2. Air / water emulsion in the elastic sleeve 13 and the chambers 12 increases the buoyancy of the dam. The fluctuation of the quantity of water discharged in time due to the irregularity of water creates conditions for the formation of the effect of the efforts of waves and interference in the expanding nozzles and the pulsators and after them, contributing to the cooling effect of warm water. Use of selective water withdrawal 10 provides a collection of over cold water in the zone of its fence, and the elevated location and their design solution is made using the criterion of Richardson.

Create a twist and ripple of the stream of warm water, the waves on the surface of the cooling pond and the water drop, and the corresponding orientation of the expanding nozzles increase the surface area of water in the pond, the surface contact between warm water and cold air, ensuring efficient heat transfer between them, allows, under certain conditions, to bring the lower chilled water temperature to a theoretically possible, but sooba cooling circulating water in the pond-cooler is a combination of the effect of twist, ripple, selectivity to improve the efficiency of the use of mirror pond-cooler for cooling and reducing the intake temperature of the cooling pond water.
