Method of and apparatus for cleaning air

Claim 1

THE METHOD OF REMOVING SMALL PARTICLES OF DUST FROM A FLOWING STREAM OF AIR COMPRISING, COLLECTING THE SMALL PARTICLES ON ONE SIDE OF A FILTER PANEL, SENSING THE PRESSURE DROP ACROSS THE FILTER FOR DETERMINING WHEN THE COLLECTED PARTICLES AGGLOMERATE TO FORM LARGER PARTICLES, WHEN THE PRESSURE DROP INCREASE TO A PREDETERMINED AMOUNT, REMOVING THE AGGLOMERATE TO FORM LARGER STREAM BY REVERSING THE FILTER PANEL RELATIVE TO THE AIR FLOW AND JARRING THE FILTER TO LOOSEN THE AGGLOMERATED PARTICLES THEREBY DUMPING THE AGGLOMERATED PARTICLES DOWNSTREAM, AND PASSING THE DUMPED PARTICLES WITH THE DOWNSTREAM AIR TO AN INTERITAL SEPARATOR, AND SEPARATING THE PARTICLES FROM THE AIR, AND COLLECTING THE SMALLER PARTICLES ON THE SECOND SIDE OF THE FILTE R AND REPEATING THE SECOND, THIRD AND FOURTH STEPS OF THE METHOD.

Claim 2

THE METHOD OF REMOVING SMALL PARTICLES OF DUST FROM A FLOWING STREAM OF AIR COMPRISING, COLLECTING THE SMALL PARTICLES ON ONE SIDE OF A FILTER PANEL, SENSING THE PRESSURE DROP ACROSS THE FILTER FOR DETERMINING WHEN THE COLLECTED PARTICLES AGGLOMERATE TO FORM LARGER PARTICLES, WHEN THE PRESSURE DROP INCREASE TO A PREDETERMINED AMOUNT, REMOVING THE AGGLOMERATE TO FORM LARGER STREAM BY REVERSING THE FILTER PANEL RELATIVE TO THE AIR FLOW AND JARRING THE FILTER TO LOOSEN THE AGGLOMERATED PARTICLES THEREBY DUMPING THE AGGLOMERATED PARTICLES DOWNSTREAM, AND PASSING THE DUMPED PARTICLES WITH THE DOWNSTREAM AIR TO AN INTERITAL SEPARATOR, AND SEPARATING THE PARTICLES FROM THE AIR, AND COLLECTING THE SMALLER PARTICLES ON THE SECOND SIDE OF THE FILTE R AND REPEATING THE SECOND, THIRD AND FOURTH STEPS OF THE METHOD.

Claim 3

An apparatus for removing small particles of dust from a conduit containing a flowing stream of air comprising, filter panel means rotatably positioned in the conduit in the path of flowing air for collecting the small particles of dust on a first side of the filter, pressure differential sensing means positioned in the conduit for measuring the pressure drop across the filter thereby determining when the collected particles agglomerate to form larger particles, means connected to the filter for rotating the filter panel means for moving the first side downstream whereby the flowing air will act to flush the agglomerated particles downstream and the second side of the filter means may be used for collecting the dust, means positioned adjacent the filter for jarring the filter means after the filter has been rotated for dumping the agglomerated particles downstream, and an inertial separator means positioned in the conduit and positioned downstream of the filter means for removing the dumped agglomerated particles from the air stream.

Claim 4

An apparatus for removing small particles of dust from a conduit containing a flowing stream of air comprising, filter panel means rotatably positioned in the conduit in the path of flowing air for collecting the small particles of dust on a first side of the filter, pressure differential sensing means positioned in the conduit for measuring the pressure drop across the filter thereby determining when the collected particles agglomerate to form larger particles, means connected to the filter for rotating the filter panel means for moving the first side downstream whereby the flowing air will act to flush the agglomerated particles downstream and the second side of the filter means may be used for collecting the dust, means positioned adjacent the filter for jarring the filter means after the filter has been rotated for dumping the agglomerated particles downstream, and an inertial separator means positioned in the conduit and positioned downstream of the filter means for removing the dumped agglomerated particles from the air stream.

Claim 7

An apparatus for cleaning dust from a flowing stream of air comprising, filter means for collecting small particles of dust to agglomerate the dust including a plurality of filter panels rotatably mounted for rotational movement for placing each side of each panel alternately facing upstream and downstream, the edges of said adjacent panels engaging each other when rotated to form a unitary filter, means connected to the filter means for alternately rotating each of the filter panels from the upstream side to the downstream side for moving the agglomerated particles downstream of the filter, spring means connected to the filter means yieldably acting to move said filter means downstream, stop means downstream of said filter means limiting the downstream movement of the filter means in response to the spring means, cam means for moving said filter means upstream against the spring means and releasing said filter means for allowing the spring means to impact the filter means against the stop means for removing the agglomerated dust, and inertial separator means positioned downstream of said filter means for removing the agglomerated dust from the air stream.
