Description

A kind of gun body rinsed for the steam generator tube sheet body refuse with central partition plate
Technical field
The invention belongs to Steam Generators in NPP service technique fields, and in particular to a kind of for the steaming with central partition plate The gun body that vapour generator tube sheet body refuse rinses.
Background technique
Steam generator, abbreviation SG are one of nuclear power plant's key equipments, play the isolation and heat exchange of one, secondary circuit Effect.Most of SG of nuclear power station uses the structure type of the vertical Natural Circulation of built-in steam-water separator at present.In nuclear power machine In group normal course of operation, even if carrying out stringent control to secondary circuit water chemistry, it can also be generated not in SG and water supply system Dissolubility corrosion product.These corrosion products, can be in the secondary side tube sheet surface SG and pipe while being discharged by drainage part The problems such as beam deposits in gap, forms body refuse accumulation, eventually leads to the decline of the heat-transfer pipe burn into thermal efficiency and unstable water level.
Domestic and international operating experience shows the deposit for periodically removing tube sheet upper surface, can slow down heat-transfer pipe corrosion and rupture Trend.As the periodical measure of SG secondary side maintenance, tube sheet body refuse hydrodynamic cleaning at home and abroad in pressurized-water reactor nuclear power plant more To be more generally applied.The technology utilizes high-pressure water jet, and the deposit in tube bank is smashed and is rushed to outer ring corridor, is passed through Circulation is driven to the suction inlet of suction system, is sucked out, to achieve the purpose that remove deposit on SG secondary side tube sheet.
Although currently, domestic since the significance and necessity of SG tube sheet body refuse hydrodynamic cleaning have had some flushings to fill Set investment practical application, but these flushers still remain problem in application process at the scene, particularly with septum cordis in band The SG of plate not can be well solved always the application problem of body refuse sluice gun in narrow space.
