汽轮机组冷却水循环系统
摘要：
本实用新型涉及热能动力工程领域领域，公开了一种汽轮机组冷却水循环系统，第一管道的一端连接到排汽管道，第二管道的一端连接到回流管道，第一管道的另一端和第二管道的另一端连接到热交换系统，第一管道上设置有第一阀门，第二管道上设置有第二阀门，第一阀门和第二阀门设置为在同时打开的状态下使得汽轮机组的排汽分别流入空冷装置和热交换系统且使得经空冷装置和热交换系统冷却后的流体流入汽轮机组的凝结水箱。通过上述技术方案，热交换系统分担了空冷装置的部分负载(蒸汽)，因此在高温时在保证机组安全的同时又兼顾了机组的经济性。
摘要（英）：

The utility model relates to the field of thermal power engineering. The utility model discloses a cooling water circulation system of a turboset. one end of the first pipeline is connected to the steam exhaust pipeline; one end of the second pipeline is connected to the return pipeline; the other end of the first pipeline and the other end of the second pipeline are connected to a heat exchange system; a first valve is arranged on the first pipeline, a second valve is arranged on the second pipeline, and the first valve and the second valve are arranged to enable exhaust steam of the turbosetto flow into the air cooling device and the heat exchange system respectively and enable fluid cooled by the air cooling device and the heat exchange system to flow into a condensate tank of the turboset in the state that the first valve and the second valve are opened at the same time. By means of the technical scheme, the heat exchange system shares part of loads (steam) of the air cooling device, and therefore the economical efficiency of the unit is considered while the safety of the unit is guaranteed at high temperature.
