A cooling system and method for a multi-pressure condenser

Abstract

The present invention relates to a cooling system and method for a multi-pressure condenser, comprising a condensing assembly, a cooling assembly and a heating assembly. The condensing assembly comprises a multi-cylinder multi-exhaust steam turbine unit, a condenser and a rotary plugging plate, wherein the condenser is connected to each cylinder of the multi-cylinder multi-exhaust steam turbine unit, and adjacent condensers are connected through a rotary plugging plate; the cooling assembly comprises a circulating water inlet pipe and a circulating water return pipe, wherein a first water inlet pipe of the condenser is connected to the circulating water inlet pipe, and a first water return pipe is connected to the condenser, and the first water return pipe is connected to the circulating water return pipe; the heating assembly comprises a heat network heater, a water supply connecting pipe, a heat network water supply pipe and a heat network return pipe, wherein a second water inlet pipe is connected to the first water inlet pipe, and the second water inlet pipe is connected to the heat network return pipe, and the first water return pipe is connected to the second water return pipe, and the second water return pipe is connected to the water supply connecting pipe, and the heat network heater is connected between the water supply connecting pipe and the heat network water supply pipe.
