Abstract
The utility model discloses a steam turbine recovery system of condensation water for controlling, sealing and cooling. The steam turbine recovery system of the condensation water for controlling, sealing and cooling comprises a drain tank, a drain pump, a condenser, a low-pressure heater, a deaerator, a controlling cooling water pipeline, a water feed pump sealing cooling water pipeline, a water recovery main pipeline, a demineralized water pipeline and a recovery water feed pipeline. The controlling cooling water pipeline and the water feed pump sealing cooling water pipeline are communicated on the water recovery main pipeline. The water recovery main pipeline is communicated with the drain tank. The drain tank, the drain pump, the condenser, the low-pressure heater and the deaerator are communicated through a pipeline. Cooling water supplied by condensation water is recovered to the drain tank by paving a pipeline, and then water in the drain tank is added to the condenser through the drain pump, the condensation water enters the deaerator after being heated by the low-pressure heater and enters a water feed system again for operation, and the condensation water for controlling, cooling and sealing is recovered so as to avoid loss of the condensation water and heat.
Description
Technical field
