Description

technical field [0001] The invention relates to the technical field of heat dissipation of cooling liquid of cooling equipment, in particular to a steam turbine cooling and heat dissipation system in a photothermal power station. Background technique [0002] In the field of traditional power generation, in order to realize the recycling of water, the exhaust steam after the steam drives the steam turbine to generate electricity needs to be cooled by cooling equipment, such as a condenser, and the cooled water is recycled. After the cooling liquid in the cooling equipment exchanges heat with the exhaust steam of the steam turbine, the temperature of the cooling liquid rises. In order to realize the recycling of the cooling liquid, it is usually necessary to perform heat dissipation treatment on the cooling liquid. [0003] There are two traditional coolant cooling methods, one is to transport the high-temperature coolant to the cooling tower for heat exchange with water to a...
