Technical water supply system of seawater pumped storage power station
The invention relates to the field of design of hydraulic machinery auxiliary systems of hydropower stations, and discloses a technical water supply system of a seawater pumped storage power station. The technical water supply system comprises a seawater outer circulation system, a fresh water inner circulation system and a unit lubrication water supply system; seawater outer circulation branches and fresh water inner circulation branches are in one-to-one correspondence and exchange heat through heat exchangers; the seawater outer circulation branches take water from a sea area or a unit main flow channel through seawater taking branch pipes communicated with the seawater outer circulation branches, and returns water to the sea area or the unit main flow channel through seawater returning branch pipes communicated with the seawater outer circulation branches; the fresh water inner circulation branches take water from a fresh water circulation water storage tank through fresh water taking branch pipes communicated with the fresh water inner circulation branches, the water outlet ends of the fresh water inner circulation branches are communicated with cooling water units, and the cooling water unit drains water to cooling fresh water recovery pipes communicated with the fresh water circulation water storage tank; and the unit lubrication water supply system takes water from the water outlet ends of the fresh water inner circulation branches or a seawater taking main pipe. According to the technical water supply system, marine organism attachment can be effectively avoided, and the seawater corrosion and fouling risks of units, equipment and pipelines are reduced.
本发明涉及水电站水力机械辅助系统设计领域，公开了一种海水抽水蓄能电站技术供水系统，包括海水外循环系统、淡水内循环系统及机组润滑供水系统；其海水外循环支路与淡水内循环支路一一对应并通过换热器热交换；海水外循环支路通过与其连通的海水取水支管自海域或机组主流道取水，并通过与其连通的海水回水支管向海域或机组主流道回水；淡水内循环支路通过与其连通的淡水取水支管自淡水循环储水罐取水，且其出水端连通各冷却用水单元，各冷却用水单元排水至与淡水循环储水罐连通的冷却用淡水回收管；机组润滑供水系统自淡水内循环支路出水端取水或自海水取水干管取水。本发明可有效避免海生物附着，降低机组、设备及管路的海水腐蚀与污损风险。
