Passive emergency air conditioning device of master control room for nuclear power plant

Abstract

The invention discloses a passive emergency air conditioning device of a master control room for a nuclear power plant. A compressed air storage tank is communicated with a vortex tube; the vortex tube is provided with a cold air outlet and a hot air outlet, the cold air outlet of the vortex tube is communicated with the heat exchange component through a cold air pipeline, and the heat exchange component is installed on the cooling beam which is hollow and communicated with the heat exchange component. Under the working condition of completely losing alternating current power supply design expansion, heat exchange between cold air and hot air in a main control room is achieved, cooling and fresh air supply functions are completed, and the hot air curtain is used for being installed at an inlet and an outlet of the main control room. A hot air outlet of the vortex tube communicates with a hot air curtain through a hot air pipeline; the micro iodine adsorber is connected to the hot air curtain, the hot air curtain covers the micro iodine adsorber, and the vortex tube separates hot air and purges the micro iodine adsorber through the hot air curtain, so that the relative humidity of the micro iodine adsorber is ensured, the purification efficiency is ensured, the purification function of the main control room is realized, the residence of the main control room under the working condition of power failure of the whole plant is practically improved, and the inherent safety of the power station is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a passive emergency air conditioner for a main control room of a nuclear power plant. Background technique [0002] With the continuous development of nuclear power technology, serious accidents in nuclear power plants have received extensive attention from global nuclear safety authorities and the International Atomic Energy Agency. All countries have realized that the possibility of serious accidents cannot be completely ruled out. Therefore, nuclear power safety work cannot only consider design basis accidents. Mitigation and response to severe incidents must also be considered. Among them, as the main control room of the nuclear power plant monitoring center, its main function is to monitor and control the normal and abnormal states of the entire nuclear power plant under various operating conditions, so as to ensure the effective and safe operation of the nuclear pow...

AI Technical Summary

Problems solved by technology

Due to the use of external power, if there is a power outage or an accident, once the nuclear power plant loses all AC power, all active systems will fail, resulting in temperature and humidity in the main control room, CO 2 If the concentration exceeds the standard, etc., the resident function of the main control room cannot be guaranteed
