Embodiment 1

[0039]Example 1, such asfigure 1 As shown, it includes a high-pressure air storage device 1 and a delivery pipe 3. The high-pressure air storage device 1 is used to store high-pressure compressed gas. One end of the delivery pipe 3 is connected to the high-pressure air storage device 1 located outside the main control room 4, and the other end is connected to The air outlet 8 in the main control room 4 is connected, and the conveying pipeline 3 includes a passive valve 33 located in the main control room 4. The emergency ventilation system also includes a pressure relief device for releasing the pressure of the main control room 4. The high-pressure air storage device 1 is connected to the pressure-reducing module. The pressure-reducing module includes a pressure-reducing pipeline and a spare pressure-reducing pipeline connected in parallel with the pressure-reducing pipeline. The gas reduced by the pressure-reducing module passes through the air outlet 8 or the spare air outlet 61 ...

Abstract

The invention relates to an emergency ventilation system for a nuclear facility master control room. The emergency ventilation system comprises a high-pressure air storage device and a conveying pipeline, wherein the high-pressure air storage device is used for storing high-pressure compressed air, one end of the conveying pipeline is connected with the high-pressure air storage device located outside the main control room, the other end of the conveying pipeline is connected with an air outlet located in the main control chamber, the conveying pipeline comprises a passive valve located in themain control chamber, and the emergency ventilation system further comprises a pressure relief device used for relieving pressure of the main control chamber. According to the emergency ventilation system, power support does not needed, the risk of retention loss of the master control room is reduced, and the safety coefficient and reliability of the ventilation system of the master control roomare enhanced.
