Abstract
A device for simultaneously filtering and humidifying an air flow uses an outer casing having a rotatable, reticulated filtering element. The air flow enters the casing and must pass through the filtering element by making abrupt change in directions. Particles in the air flow, due to their greater inertia, will not be able to follow the air flow and, therefore, will not pass through the filtering element. There are expelled through an opening. The air flow exists through an outlet that is within the perimeter of the filtering element. A water projector serves to both humidify the air flow and wetten the filter elements surface in order to capture particles in the air flow.
Claims6
An air filtering and humidifying device comprising;
- an outer casing having an air inlet and an air outlet;
- a water projector extending into the outer casing;
- a rotatable, reticulated filter element having an inner and outer surface inside the outer casing;
- the filter element comprising a first cylinder, the first cylinder made from a series of axially spaced continous bands circular, each band formed by concentric elements joined together;
- each element extending radially inwardly and adjoining elements having a different axial direction.
