FIELD: power industry.SUBSTANCE: thermal power station is equipped with a recirculating water supply system of a cooling tower, which are connected to each other through hydraulic circuits of water treatment and consumption; at that, cooling towers have separate hydraulic circuits of water treatment and consumption, which include a housing, in the lower part of which at least two water collecting tanks are located, which are connected to each other through a compensating pipe providing hydraulic independence of circuits of service water treatment and consumption; at that, one tank is connected to a pump that supplies the water cooled in the cooling tower to a consumer, which is again supplied through a valve via the pipeline to the second tank, from which the water heated with a pump is supplied through the filter and the valve via the pipeline to a header with atomisers arranged in upper part of the cooling tower housing, and in the section between the filter and the valve there installed is a monitoring system of fluid resistance of the filter, which consists of a pressure gauge and a valve.EFFECT: invention allows increasing economy of a thermal power station.2 dwg |
