Parallel Blade Mist Eliminators are commonly used for removal of mist droplets larger than 10 microns. These devices utilize fixed parallel blades positioned vertically or horizontally in a vessel. The blades are usually of a chevron or a wave design creating a narrow irregular passage way through the blades themselves.
As the air stream passes through the vessel, the blades cause the air to change direction in a "zig-zag" motion. This motion causes the liquid droplets to contact the blades and collect at the bottom of the vessel. The liquid is then drained away from the vessel where it can be stored, recovered or disposed of. These devices also utilize spray headers for periodic washing and cleaning.
