    A cooling system for condensing the exhaust steam of steam turbine plants, particularly of power plants, comprises a mixing condenser (12) connected to the outflow of the steam turbine (10), a dry cooling tower (14) connected to the cooling water circuit (18,22) of the mixing condenser, and a wet cooling apparatus provided inside the cooling tower. The wet cooling apparatus (28, 30, 32, 34, 36) is located at least partly in a box (40) for conducting ambient cooling air into the cooling tower (14), the box (40) being arranged inside the cooling tower (14). The wet cooling apparatus may comprise a wet surface heat exchanger (26), or, alternatively, water spraying means (64, Fig. 4). The box further encompasses a dry surface heat exchanger (44) provided after the wet cooling apparatus (28, 30, 32, 34, 36) as regards the flow direction (42) of cooling air. The air withdrawn from the wet cooling apparatus becomes warmed up while traversing the dry surface heat exchanger (44) and, thus, does not diminish the draft of the cooling tower (14) when mixing with the air flowing in through the main heat exchangers (16) of the latter.

    This invention relates to cooling systems for condensing steam from steam turbines, in particular power plants.
    A known cooling system for a condenser of steam turbines, comprising a mixing condenser connected to the output of a steam turbine, a dry cooling tower with a main heat exchanger, a heat exchanger with a wet surface located in the cooling water KOHffp connected to the cooling water of the mixing condenser. encased in a casing, having a fan in the outlet opening, and a pool of water stored in the lower part of the casing and reported to the piping ode with a pump with a heat exchanger spray device with a wet surface.
    A disadvantage of the known cooling system is the low operating efficiency at elevated ambient temperatures.
    The aim of the invention is to increase operating efficiency at elevated ambient temperatures.
    The goal is achieved by the fact that the system is equipped with an additional heat exchanger installed in the casing during the air movement behind the heat exchanger spray device with a wet surface and connected in series with the latter to the cooling water circuit. In addition, in the lower part of the casing wall, opposite to its entrance aperture, an adjustable window is made, which additionally has adjustable flaps

    A heat exchanger with a wet surface is located under an additional heat exchanger, and a spray device is placed between the heat exchangers. An additional heat exchanger may be located behind the heat exchanger with a wet surface in the horizontal direction, and the casing is provided with vertical partitions, one of which is installed in front of the heat exchanger with a wet surface with a gap relative to the top casing and fixed on its bottom, and the other between the mentioned heat exchangers with a gap relative to Nishcha and secured on top of the housing to provide a zigzag direction of cooling air.
    FIG. Figure 1 shows a condenser cooling system with an additional heat exchanger located above a wet-surface heat exchanger; FIG. 2 shows a system with the installation of an additional heat exchanger behind a heat exchanger with a wet surface in the horizontal direction,
    The cooling system of the steam turbine condenser contains a mixing condenser 1 connected to the output of the steam turbine 2, a dry cooling tower 3 with the main heat exchanger 4 located in its inlet aperture. The main heat exchanger 4 is connected to the cooling water circuit 5 of the mixing condenser 1. Inside the cooling tower 3, the main heat exchanger 4 is equipped with a wet surface along the air path. The heat exchanger b is enclosed in a casing 7 having a fan 8 in the outlet opening. In the lower part of the casing 7 there is a pool 9 of water supply, communicated by pipe 10 to the pump 11 with a spraying device 12 of the heat exchanger 6 with a wet surface. The cooling system is equipped with an additional heat exchanger 13 installed in the casing 7 along the air movement behind the spraying devices 12 of the heat exchanger 6 with a wet surface and connected in series with the heat exchanger b to the cooling water circuit. In the lower part of the casing wall 7, opposite to its entrance aperture, a window 14 is made, in which adjustable flaps 15 are additionally installed.
    The heat exchanger 6 with a wet surface can be located under the additional heat exchanger 13, and the spray devices 12 are placed between the heat exchangers 6 and 13 (Fig. 1). Additional heat exchanger 13 may
    be located behind the heat exchanger 6 in the horizontal direction (FIG. 2). While the casing 7 is equipped with vertical partitions 16, one of which is installed
    5 in front of the heat exchanger 6 with a gap relative to the top of the casing 7 and secured to its bottom, and the other between the heat exchangers with a gap relative to the bottom and secured to the top of the casing 7 to provide for sublimate cooling air.
    The cooling water circulation circuit is provided with a pump 17 installed between the condenser 1 and the main heat exchange 5 nick 4. The water supply to the spraying devices 12 is controlled by a pulse from the water temperature sensor 18 in the cooling circuit installed at the outlet of the condenser 1.
    The condenser cooling system operates as follows.
    The exhaust steam of the steam turbine 2 enters the mixing condenser 1,
    5 where it condenses when the cooling water circuit 5 is mixed with the return water. The mixture of condensate and water is supplied by the pump 17 to the main heat exchangers 4 and to the heat exchangers 6 and 13, where
    0 it is air cooled. At low ambient temperatures, heat exchangers 6 and 13 can operate with a dry surface. With a high ambient temperature (in summer), the main heat exchangers 4 are not capable of providing the necessary cooling of the condensate. In this case, the signal from the sensor 18 turns on the pump 11, which in line 10 supplies water from the pool 9
    0 to the spray devices 12. When water is supplied to the surface of the heat exchanger 6, the latter is moistened and the intensity of heat exchange increases substantially. Relatively cold air
    5 leaving the heat exchanger 6, is heated by passing through the additional heat exchanger 13, which leads to additional cooling of the return water passing successively from the heat exchanger 6 to the heat exchanger 13 and further to the cooling water circuit 5. With horizontal placement of heat exchangers 6 and 13, the installation of partitions 16 provides a zigzag direction for the movement of cooling air, with air coming from the top to the heat exchanger 6 and to the bottom to the heat exchanger 13.
    As a result of the use of the invention, the efficiency of the cooling system of the condenser with
    elevated ambient temperatures, the cooling capacity of the system being ensured without increasing its dimensions.
