Abstract
An air filtration and aromatizer apparatus which includes a housing, a motor in the housing with a fan for drawing air through an inlet toward an outlet through a pollution-collecting chamber, and an elongated hollow tubular perforated member having an upper end connected to the motor output shaft and a lower end disposed in a bath of water. The hollow tubular member is formed in such a manner that as it is rotated by the motor, it draws water from the container under the influence of centrifugal force, and then forces the water through the perforations to form a mist or rain-like atmosphere in the path of motion of the air passing from the housing inlet toward the housing outlet.
Claims9
An air filtration apparatus, comprising:
- a housing having a pollution-collecting chamber for holding water that partially fills the chamber, an air inlet and an air outlet, both disposed above the surface of water in the pollution-collecting chamber;
- a motor;
- a fan mounted within the housing and connected to the motor for drawing air into said pollution-collecting chamber through the air inlet and for exhausting air from the pollution-collecting chamber through the air outlet;
- an elongated vertical tube having a lower inlet end disposed in water in the pollution-collecting chamber;
- means for connecting the vertical hollow tube to the motor for rotating the tube about a vertical axis;
- the vertical tube having a plurality of vertically spaced openings supported above the water level in the pollution-collecting chamber, for discharging water received through said lower inlet end of the tube, as a spray under centrifugal force as the tube is rotated, into air containing wetable pollutants and passing upwardly along a path adjacent the tube;
- and
- whereby polluted air enters the pollution-collecting chamber and then passes upwardly adjacent to the opening means and through the spray to wet the wetable pollutants whereby the wetable pollutants remain in the pollution-collecting chamber, and the air passes toward said air outlet.
A method for removing pollutants from air containing pollutants, comprising the steps of:
- providing a housing having a pollution-collecting chamber, an air inlet for receiving air into the pollution-collecting chamber and an air outlet for passing filtered air from the pollution-collecting chamber
- providing a body of water in the pollution-collecting chamber;
- providing a motor having a rotatable output shaft, and fan fan means for passing air from the air inlet toward the air outlet;
- connecting an elongated vertical tubular member to the output shaft for rotation;
- and
- rotating the tubular member such that a lower inlet opening in the body of water draws water into the tubular member, and then discharges the water through a plurality of vertically speced openings in the tubular member into the chamber to form a rain-like mist in the vertical tubular member;and in the path of air passing through the pollution-collecting chamber whereby the mist separates wetable pollutants from the air.
