Abstract | The utility model belongs to the technical field of nuclear power plant equipment maintenance, and particularly relates to an exhaust device of a nuclear power plant nuclear island drainage exhaust system, which is characterized in that a set of exhaust device is connected in parallel on an exhaust pipeline at the top of nuclear island voltage stabilizer equipment, and two tee joints, an isolating valve, a vacuum pump (vacuum ejector) and the like are additionally arranged on the original pipeline. The vacuum ejector is powered by compressed air, and exhaust gas mixed with gas of the primary loop returns to a nuclear island drainage exhaust system. According to the device for the primary loop flushing stage after overhaul of the nuclear power station, the vacuum ejector is additionally arranged on the exhaust pipeline through a set of exhaust device of a nuclear island drainage exhaust system, primary loop gas is exhausted through the vacuum ejector, and water is filled into a primary loop. Maintenance compre |
