Problems solved by technology
[0005] However, after entering summer, due to the high ambient temperature and high humidity, the temperature of the circulating cooling water is often higher than the design value, resulting in excessively high condenser back pressure, reduced load operation of the steam turbine, and reduced power generation of the system

The invention discloses a circulating cooling water system special for a power plant. The circulating cooling water system special for a power plant comprises a condenser, mechanical draft cooling towers, a water pool arranged below the cooling towers, a circulating water tank and a circulating cooling water pipeline. The condenser is connected with the water pool and the circulating water pump through the circulating cooling water pipeline. A heat exchanger is arranged in the water pool and is connected with a water chilling unit through a water chilling pipeline. The water chilling unit obtains heat through a waste heat conveying pipeline. By means of the circulating cooling water system special for the power plant, waste heat (such as flue gas and waste water) in a power plant is used for being refrigerated through the water chilling unit (such as a lithium bromide unit), low temperature cold water (with the temperature ranging from 6 DEG C to 8 DEG C) is obtained, the low temperature cooling water exchanges heat with circulating cooling water in the water pool through the heat exchanger arranged in the cooling water pool, the temperature of the circulating cooling water is further reduced, and therefore the back pressure of the condenser is reduced, and the power generating amount of a turbine is increased.
Description
technical field [0001] The invention relates to the technical field of steam turbine cooling in a power plant, in particular to a special circulating cooling water system for a power plant. Background technique [0002] In the existing steam turbine power plant, among the many auxiliary systems of the steam turbine, the circulating cooling water system is a huge power system, which ensures the best vacuum operation of the condenser and plays a vital role in the safety and economy of the power plant operation. important role. [0003] Existing cooling water systems such as figure 2 As shown, the circulating water entering it is usually cooled to a certain temperature by means of a mechanical ventilation cooling tower, and flows into the cooling water pool; the water in the cooling water pool is pumped to the condenser through the circulating water, and the steam in the condenser After heat exchange, it is sent to the mechanical ventilation cooling tower through the circulat...
