| titleOfInvention | Processing apparatus of steam is revealed to steam turbine axle head gland |
| abstract | The utility model discloses a processing device for steam leakage of a steam seal at the shaft end of a steam turbine, which comprises a first heat exchanger, a second heat exchanger, a booster pump, a steam seal cooler, a steam seal air extractor, a steam conveying pipeline, a ventilation pipeline and a control valve; the steam seal cooler is a shell-and-tube cooler; the steam seal air extractor adopts a steam ejector; the initial section of the steam transmission pipeline is respectively connected with a left shaft end steam seal and a right shaft end steam seal of the turbine main shaft, the tail section of the steam transmission pipeline is connected with a steam inlet of a steam seal cooler, and a first heat exchanger, a second heat exchanger, a booster pump and a control valve are sequentially connected in series on the pipeline. The utility model adopts the pre-treatment which takes two-stage heat exchange as the leading part, so that the temperature of the steam to be cooled can be effectively reduced, and the reasonable optimization of cooling and air extracting machinery is added, so that the steam leaked from the steam seal at the shaft end of the steam turbine finally becomes the condensed water completely; the scaling degree of the steam seal cooler is obviously reduced, and the normal use of the steam seal cooler is ensured. |
