摘　　要：结合具体脱硫系统改造工程,以原电厂的水文条件及循环水系统的设计方案为基础,根据海水脱硫系统的用水要求,分析海水脱硫工艺对直流供水系统的影响,在满足电厂安全运行要求的前提下,充分考虑利用循环水系统已有建(构)筑物,提出高程系统的优化方案,既实现循环水系统的节能优化,又避免大范围的循环水系统改造,同时降低改造工程的投资。Combined with the specific seawater desulfurization transformation project,based on the hydrological conditions and the design scheme of the circulating water system of the original power plant,and according to the water requirements of the seawater desulfurization system,this paper analyzes the influence of seawater desulfurization process on once through water supply system,and fully considers the use of the existing buildings of the circulating water system on the premise of meeting the safe operation requirements of the power plant.The optimization scheme of elevation system is proposed,which not only realizes the energy-saving optimization of circulating water system,but also avoids the large-scale transformation of the circulating water system,and reduces the investment of the transformation project.
