Description
Technical Field
The invention relates to the technical field of cooling water systems of thermal power plants, in particular to a direct-current-like cooling water supply system.
Background
The design of cooling water supply systems is an important issue in the design of thermal power plants. Whether the selection of the type of cooling water supply system is reasonable or not has an important influence on the safe and economical operation of the thermal power plant. The cooling water supply system comprises a direct-current water supply system and a circulating water supply system. The direct current water supply system has large cooling water consumption of a power plant, and along with the limitation of environmental protection requirements, other newly built or expanded power plants except a coastal power plant need to adopt a circulating cooling water system at present, and particularly the circulating cooling water system taking a cooling tower as a cooling structure is most applied. The arrangement scheme and flow of a circulating water supply system based on a cooling structure such as a cooling tower are generally as follows: a cooling tower water collecting tank, a circulating water channel, a sewage removal device, a circulating water pump, a circulating water pipe, a heat exchanger, a circulating water pipe and a cooling tower. The scheme has the defects of large water consumption, large noise pollution, large occupied area, more consumables, large engineering quantity and the like, and with the guidance of energy-saving and consumption-reducing policies, more and more projects seek new water supply systems to achieve the purposes of energy saving and noise reduction.
Disclosure of Invention
