Embodiment Construction

[0026] Such as figure 1 , 2 As shown, a steam exhaust device for the auxiliary system of the nuclear island includes a shroud 2 for pressurizing and diverting the exhaust steam at the exhaust steam outlet 1 of the auxiliary water supply system of the nuclear island. The steam collecting hood assembly in which the exhaust steam outlet 1 and the deflector 2 are closed, the upper part of the steam collecting hood assembly is connected with the exhaust pipe 5 which discharges the exhausted steam to high altitude, and the lower part is connected with the condensed water discharge pipe 6.

[0027] The top of the wind deflector 2 is provided with a wind deflector outlet 21, and the wind deflector 2 is a truncated cone shape, and the wind deflector outlet 21 is smaller than the wind deflector inlet at the bottom of the wind deflector 2, because the inner wall of the wind deflector 2 is from top to bottom. A flat or curved surface with a smooth transition, preferably a conical surface...

Abstract

The invention discloses a steam exhaust device of a nuclear island auxiliary system, which is used for exhausting bled steam in a water supply system and comprises a flow guide hood which is covered on a bled steam outlet of the nuclear island auxiliary water supply system and used for carrying out pressurization and flow guide on the bled steam, a steam collection hood component which closes thebled steam outlet and the flow guide hood therein is arranged outside the flow guide hood, the upper part of the steam collection hood component is connected with a steam exhaust pipeline which exhausts the bled steam to high altitude, and the lower part is connected with a condensate discharge pipe. The invention provides the steam exhaust device of the nuclear island auxiliary water supply system, which has simple structure and convenient treatment, and can protect the devices in the system and the surrounding environment from being infringed.

Description

technical field [0001] The invention belongs to the technical field of a million-kilowatt advanced pressurized water reactor nuclear power plant, and more specifically relates to a steam exhaust device for a nuclear island auxiliary system. Background technique [0002] In the nuclear island auxiliary water supply system (L1 / 2ASG) of Ling Ao Nuclear Power Plant No. Standby state, that is, in the standby state, the steam heating should be maintained for a long time, so that it can be started quickly when an emergency start is required. During warm-up operation, the exhaust steam generated is not reused and is directly discharged into the surrounding environment. Due to the waste steam emission of warm-up design in 18m 3 At about 100°C, the exhausted steam has not been treated in any way, and it diffuses everywhere in the system, and condensed water overflows, causing corrosion and peeling off of the nearby gantry and cement walls, and in addition, those in a humid environme...
