The invention relates to a dead steam condensation system of an air cooling unit of a thermal power plant and provides an efficient composite steam condensation system. The efficient composite steam condensation system is a direct air cooling condensation system composed of an air cooling condenser (11), a turbine (1), a main exhaust pipeline (12), an exhaust device (2), a condensation water tank (7) and a vacuumizing system (10). The steam condensation system is further provided with a closed cooling tower (6). An outlet of the closed cooling tower (6) is communicated with the main exhaust pipeline (12). The lower portion of the main exhaust pipeline (12) is provided with a water storage tank (4) communicated with the main exhaust pipeline. The water storage tank (4) is communicated with an inlet of the closed cooling tower (6). A pipeline between an outlet of the closed cooling tower (6) and the main exhaust pipeline and a pipeline between an inlet of the closed cooling tower (6) and the water storage tank (4) are each provided with an adjusting valve. By means of the dead steam condensation system, high-position output can be achieved all the year around, and high economical efficiency is kept.
Description
technical field [0001] The invention relates to a exhaust steam condensing system of an air-cooling unit in a thermal power plant, in particular to a high-efficiency composite steam condensing system. Background technique [0002] At present, the steam condensing system of thermal power plants in areas lacking in water resources mostly adopts the direct air condensing system. The exhaust steam of the steam turbine directly enters the air-cooled condenser for condensation with air, and the air and steam perform heat exchange. The required air is usually supplied by mechanical ventilation. The air condensing system has the characteristics of free and easy-to-obtain air medium, low corrosion, and low equipment maintenance costs. However, the condensation effect of the air-cooled condenser depends on the dry bulb temperature of the air, especially when the ambient temperature is high in summer, the air-cooled condenser cannot reach the design value, and the condensation temperat...
