AIR PURIFICATION SYSTEM AND METHOD

摘要

The present invention relates to a Wet Electrostatic Precipitator Air (WEPA) Purifier (30) and purification method capable of stand-alone operation as the principal air purification system, particularly in military applications. This system is intended to supply small military units within a temporary structure clean, threat-free fresh air for periods up to 12 months without maintenance The WEPA Purifier (30) is configured to remove and sterilize biological threat particles from an airflow, and further remove and sequester radioactive particulates, thus allowing them to be safely removed at normal maintenance periods. The WEPA Purifier (30) includes a wet electrostatic precipitator filtration element in which particles are charged and collected by a capturing solution flowing over an attracting electrode collection plate (34). The water is returned by gravity to a reservoir (61) where it is disinfected and captured particles retained in a small, low maintenance, regenerative liquid filter.
