The invention relates to a power system, namely to devices for cooling the circulating water of industrial enterprises and power plants.

The purpose of the invention is to improve reliability by eliminating frostbite valves.

FIG. I shows the cooling tower, a general view; in fig. 2 - installation of valves on the tubes; in fig. 3 - valve.

The cooling tower contains a vertical case I, placed in the case of a fan 2, a droplet separator 3, a water distributor 4, Sprinkler 5. In the lower part of the case 1 there is a collection of 6 cooled water. In the air inlets 7, there are tubes 8 and 9 with installed aa them with the possibility of rotation of the flap valves 10, made in the form of sealed shells 11 of elastic material connected to a source of compressed air (not shown). The water distributor 4 is connected to the pipeline 12 with cooling water. - Tubes 8 and 9 are connected to the pipeline 12 by pipes 13 and 14, respectively. The pipes 13 and 14 are installed, the valves 1 5 and 16 are closed. On the pipe 12, the valves 17 are installed.

When the cooling tower is operating at negative ambient temperature conditions, valves 16, 15 and 17 are open, water is cooled to the water distributor 4 and pipes 8 and 9, heating the air inlet manifold

windows 7. By turning the valves 10 to a certain position, an optimum mode of heat and mass transfer of the cooled water and incoming air is ensured. The signal for changing the position of the valves 10 is a change in the chilled water temperature. In case of formation of an ice crust (frosting) on the surface of the valves 10, compressed air is pulsed in them, which inflates the casing II of the valves 10 and destroys the ice crust. Under operating conditions at positive ambient temperatures, the valves 10 are set to the position of maximum air flow, valves 15 and 16 are closed. In addition, the removal of valves 10 is permitted.

Claims (1)

Invention Formula A cooling tower containing a vertical case with air inlet windows, a water distributor placed in the case, connected to the cooled water pipeline, a sprinkler installed in the windows and connected to the pipeline tubes with flap valves that can be rotated on them, that means that, in order to increase reliability by eliminating frostbite of the valves, the latter are made in the form of hermetic shells of elastic material connected to an additionally installed source of compressed air.
