Problems solved by technology

[0002] Hualong One is the latest third-generation nuclear power technology with completely independent intellectual property rights in my country. One of the key technical points is that the seismic design standard is increased from 0.2g of the second-generation plus nuclear power plant to 0.3g, that is, the seismic design standard is increased by 50. %, the nuclear-grade air handlers currently used in CPR1000 and EPR nuclear power plants cannot meet the requirements, and it is necessary to develop a nuclear-grade air handler with particularly strong earthquake resistance to meet the use requirements of Hualong No. 1 nuclear power plant

Abstract

The invention relates to a nuclear grade air treatment unit. The nuclear grade air treatment unit is provided with an air inlet and an air outlet; a primary filter, a high-and-medium efficiency filter, a surface cooler, a dry type water disc, an electric heater, an electric humidifier and an air supply device are sequentially arranged in a unit box body in the airflow direction; a filter bent is arranged between the primary filter and the high-and-medium efficiency filter; the primary filter is pressed and fixed on the windward side of the filter bent through a fixing device; the high-and-medium efficiency filter is pressed and fixed on the leeward surface of the filter bent through a locking device; the dry type water disc is inserted into the unit box body and is placed on a base of theunit box body in a extractable mode; an anti-dripping guide plate is arranged at the top edge of the air inlet end of the dry type water disc; and the air supply device is connected with a check valvethrough a soft connection. The nuclear grade air treatment unit has the advantages of being high in anti-seismic capability, excellent in performance, resistant to irradiation and corrosion, good insealing performance, convenient to maintain, safe, reliable, long in service life and the like.
