Circulating water system arrangement structure of 1000MW secondary reheating unit

The utility model relates to a circulating water system arrangement structure of a 1000MW secondary reheating unit. At present, as a water-feeding pump turbine condenser is independently arranged, one unit has two condensers, namely a main turbine condenser and a water-feeding pump turbine condenser. The circulating water system arrangement structure of the 1000MW secondary reheating unit comprises a small machine condenser (9) and a main machine condenser (10), the small machine condenser is divided into a small machine condenser area A and a small machine condenser area B, the small machine condenser area A is connected with an A-side circulating water inlet pipe (1) and an A-side circulating water outlet pipe (3), and the main machine condenser area B is connected with an A-side circulating water outlet pipe (4). The small machine condenser area B is respectively connected with a side B circulating water inlet pipe (2) and a side B circulating water outlet pipe (4), the main machine condenser outer ring is
