Abstract: A reusable metal air pre-filter was designed based on the requirements and framework documents of the air supply system in the AC building of a nuclear power plant, and was compared with the installation scheme and operating pressure difference of the original air pre-filter in the nuclear power plant. The results showed that after running for the same time, the upstream and downstream pressure and pressure difference increase ratios of the metal air pre-filter are lower than those of the original air pre-filter, indicating that the metal air pre-filter operates more stably. When the final resistance is reached, the metal air pre-filter can be cleaned and reused, which will have good application prospects.

Key words: nuclear power plant, air filtration, metal air pre-filter
