Abstract

The invention belongs to the technical field of nuclear island exhaust and drainage systems, and particularly relates to a system and method for flushing a drainage tank of a nuclear power station and equipment. According to the system for flushing the drain tank of the nuclear power station, demineralized water in a first flushing pipeline and condensed water in a fifth flushing pipeline can be used for flushing the first separation drain tank; demineralized water in a second flushing pipeline and condensed water in a sixth flushing pipeline can be used for flushing a first regeneration drain tank; the demineralized water in a third flushing pipeline and the condensed water in a seventh flushing pipeline can be used for flushing a second separation drain tank; and demineralized water in a fourth flushing pipeline and condensed water in a eighth flushing pipeline can be used for flushing a second regeneration drain tank. According to the system and method for flushing the drain tank of the nuclear power station and the equipment, the flushing efficiency of the drain tanks is improved, and the flushing time is shortened.

Description

technical field [0001] The invention belongs to the technical field of exhaust and drainage systems of nuclear islands, and in particular relates to a flushing system, method and equipment for drainage tanks of nuclear power plants. Background technique [0002] The steam produced by the steam turbine unit of a nuclear power plant is saturated steam. After the saturated steam enters the high-pressure cylinder of the steam turbine and initially expands to do work, it will be transformed into wet steam with a water content of 10% to 15%. If the wet steam is directly discharged into the low-pressure cylinder of the steam turbine to continue Expansion works, so the water content of the wet steam in the low-pressure cylinder will reach 20% to 25%. [0003] Wet steam will greatly reduce the working efficiency of the steam turbine unit, and will cause erosion and damage to the blades of the low-pressure cylinder. At the same time, it will also cause the blades of the low-pressure c...
