ABSTRACT:
Apparatus for the collection and removal of mercury vapor from the air. Atmospheric air containing mercury vapor is forced by a blower through a sulfur filter, through an electrostatic precipitator, and into an iodine impregnated, activated charcoal filter. The air moving through the sulfur filter picks up sublimized sulfur and, as the resulting vapor phase sulfur passes through the electrostatic precipitator, some of it reacts with ozone formed therein to form sulfur compounds which are absorbed, along with elemental sulfur, on the iodine impregnated, activated charcoal filter. Some of the mercury vapor not removed from the air as the air is moved through the sulfur filter is removed in the electrostatic precipitator and most of the remaining mercury vapor is removed by subsequent passage through the iodine and sulfur impregnated, activated charcoal filter.
