AN APPARATUS FOR CLEANING STEAM GENERATORS OF NUCLEAR POWER PLANT USING HIGH PRESSURE WATER SPRAY

摘要

The present invention is a nuclear power plant steam generator cleaning apparatus using high pressure water injection to remove the sludge accumulated on the surface of the heat pipe and the lower support plate of the steam generator by spraying the high pressure water by a cleaning robot having a spraying angle of various angles. It is about.;To this end, the present invention, in the steam generator cleaning apparatus for removing the sludge accumulated on the surface of the heat transfer tube of the steam generator and the upper portion of the lower heat transfer tube by spraying high pressure water by a cleaning robot having a spraying angle of various angles, Install the rail guides on both sides of the spare cylinder between the separation plate and the heat pipe through the hand tool of the steam generator to both sides of the fixed cylinder, and enter the rail deeply to both sides of the fixed cylinder through the rail guide. It is installed to the rail guide and the fixed wire installed over the rail guide and the rail using a tensioner using a wire tensioner to firmly fix the rail guide and the entire rail, and consists of a structure for installing a high-pressure water jet cleaning robot on the rail.;According to the present invention made as described above, it is possible to more safely and reliably remove the sludge deposited on the heat transfer tube surface and the heat transfer tube lower support plate of the steam generator.;Cleaning Robot, Rail Guide, High Pressure Water Jet, Heat Pipe, Scorpion
