Example Embodiment
[0021] The present invention provides an exhaust pipe structure for antifreezing of a direct air condenser in winter. The present invention will be further described below with reference to the drawings and specific embodiments.
[0022] Such as figure 1 with figure 2 Shown is a schematic diagram of a steam turbine exhaust pipe of a 300MW direct air cooling unit. The steam turbine exhaust pipe 6 is connected to the steam distribution pipes 7 of each row of the air condenser through 6 parallel rising pipes 1, and each steam distribution pipe 7 is connected side by side with 5 groups of condenser units 3, each group of condenser units The lower end of 3 is connected by the condensate collection pipe 2; each group of condenser units 3 is divided into two pieces arranged diagonally left and right to form an inverted "V" structure; in the 5 groups of condenser units 3, the downstream unit and the countercurrent unit The units are arranged at intervals, and both ends are downstream un...
