Description

one

The invention relates to the field of power engineering, in particular, devices for cooling reverse water in thermal and nuclear power plants.

A known tower cooling tower, containing a sprinkler mounted on a frame with a disconnected peripheral part i,

Heat transfer in winter time with a decrease in the hydraulic load and the danger of frosting of elements in this cooling tower is regulated by switching to work only with the central part of the irrigator with a local increase in the specific hydraulic load. In this case, the water supply to the peripheral part of the irrigator is stopped.

However, such a cooling tower does not provide reliable operation in the winter, although dangerous freezing of the elements of the cooling tower can be avoided.

A cooling tower is also known, which contains a sprinkler placed in a frame with columns installed on the foundation of the catchment basin 2j. The supply and distribution of hot water throughout the irrigation area is carried out vertically located at the inlet

channel pressure pipelines, which simultaneously play the role of the supporting elements of irrigation.

However, part of the vertical feed pipes, especially in the peripheral part of the cooling tower, are disconnected in the winter time in order to reduce the hydraulic load on the ice, which leads to a decrease in the reliability of the operation of the city.

The aim of the invention is to provide a deeper cooling of the waters and increase the reliability of operation during the winter. For this purpose, the lower part of each rack is made in the form of a heat pipe filled with light boiling liquid, with fins on the walls of the condensation zone.

FIG. 1 shows a general view of the cooling tower; in fig. 2 is a longitudinal section of the rack in FIG. 3 is a section along A-A in FIG. 2

Under the tower 1 of the cooling tower there is a drainage basin 2, on the foundation of which stands 3 are located. On the supporting beams 4 an irrigator 5 is installed. The lower part of each stand is made in the form of a heat pipe 6, the internal cavity 7 of which is filled with boiling liquid. The main part of the heat pipe is provided with lengthwise or ribs 8. A conduit 9 is designed to supply circulation water directly to pool 2. In winter, when the hydraulic flow decreases, circulation water flows through conduit 9, enters pool 2, sprinkler, and cools as a result of contact with heat pipes b Edges 8 intensify the removal of heat into the environment. When the air temperature in tower 1 is lower than the temperature of the water in the pool, 2 g of boiling liquid in cavity 7 boils, perceiving the heat of water. The steam generated during boiling rises to the upper part of pipe b, where it condenses, returning heat to condensation through the fins 8 to the outside air. The condensate drains over the inner surface of the pipe 6. Stands 3 perform a dual function, namely, they are the supporting elements of the water-cooling devices and heat exchangers, allowing to intensify the process of heat removal from the pool water and to provide a deeper

(/ g some of its cooling. In addition, the possibility of skipping the desired flow of circulating water through the pool, mine sprinkler during winter time completely eliminates dangerous freezing of the sprinkler elements. Formula of the Cooler Tower containing the sprinkler placed in the frame with racks installed on the foundation drainage basin, characterized in that, in order to more deeply cool the water and increase the reliability of operation in winter, the lower part of each rack is made in the form of a heat pipe filled with a light boiling liquid Tyu, with fins on the walls of the condensation zone.
