Three problems were discussed in this paper about non- cyclic desulfurized seawater cooling system, including treatment of foams in the cyclic cooling water, siphonic water- collectin well display, and the cooling system surplus energy utilization. The siphonic water - collecting well was suggested to be canceled in this paper. This suggestion would simplify the cooling system of the power station, decrease the occupation of land, save the investment, and realize the energy -saving design concept.%探讨了带海水脱硫的直流供水冷却系统中循环冷却水排水泡沫的处置,虹吸井的设置以及冷却系统的余能回收利用三方面问题.提出了取消虹吸井,简化了电厂供水冷却系统、减少占地、节约投资,体现了节能的设计理念.
