The invention provides a recovery system and a recovery method for desalting water leaked from a rotor cooling water generator water-intake water ring sleeve, in order to recover the desalting water leaked from the rotor cooling water generator water-intake water ring sleeve of a double-water internal cooling steamer generator water-cooling system so as to save energy. An outlet of a stainless steel closed funnel is connected to an inlet of a water-intake pipeline; a viewing window is arranged on the stainless steel closed funnel; an outlet of the water-intake pipeline is connected to a low-pressure heater drain tank or a desalting water pre-treatment device; an inlet of a water discharge pipeline communicates with the low-pressure heater drain tank; a regulating valve set is arranged on the water discharge pipeline; an inlet of a water return pipeline communicates with the water discharge pipeline and an outlet of the water return pipeline communicates with the low-voltage heater drain tank; and a water return valve is arranged on the water return pipeline. The stainless steel closed funnel is in charge of collecting the desalting water; and the desalting water in the water-intake pipeline is conveyed to the either the low-voltage heater drain tank or the desalting water pre-treatment device by virtue of the stainless steel closed funnel.
Description
technical field [0001] The present invention relates to a system and method for recovering desalinated water from leakage of rotor cooling water generator inlet water ring sleeve, in particular to a method for leaking rotor cooling water generator inlet water ring sleeve of a dual-water internal cooling turbo generator water cooling system A system and method for recovering desalinated water. Background technique [0002] At present, in power plants, the water-cooling system of the double-water internally cooled turbogenerator is used to prevent the rotor cooling water generator inlet water ring made of metal from overheating and improve the safety of the unit. The rotor cooling water generator inlet water ring The jacket must continuously drain desalinated water. [0003] Such as figure 1 As shown, the desalted water leaked from the current rotor cooling water generator inlet water ring is generally discharged into the unpressurized drain pipe, and then flows into the wat...
