Abstract
Abstract A wet scrubber having spray means for spraying a liquid into a passageway, and a rod scrubber positioned downstream of the spray means by which impurities can be removed from the gas stream. The rods of the scrubber are rotatably mounted, so that they can be rotated to a position parallel to the gas flow when it is desired. The rods are removably attached, so that they can be readily replaced if the need arises.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
66 words
In a wet scrubber for removing impurities from gases, passage means through which the gases flow, spray means for spraying a liquid into the passage means, a plurality of parallel, spaced, rod means extending transversely across the passage means doWnstream of the spray means, and means for rotating the rod means 90*, so that the rod means are parallel to the axis of the passage means.
Claim 2
Dependent Claim
66 words
In a wet scrubber for removing impurities from gases, passage means through which the gases flow, spray means for spraying a liquid into the passage means, a plurality of parallel, spaced, rod means extending transversely across the passage means doWnstream of the spray means, and means for rotating the rod means 90*, so that the rod means are parallel to the axis of the passage means.
Claim 3
Dependent Claim
49 words
The wet scrubber set forth in claim 1, wherein each of rod means is made up of an inner rod, and an outer sleeve surrounding inner rod, and means for removably securing the outer sleeve to the inner rod, so that the outer sleeve can be replaced when desired.
Claim 4
Dependent Claim
146 words
In a wet scrubber for removing impurities from gases, passage means through which the gases flow, spray means for spraying a liquid into the passage means, a plurality of first parallel, spaced, rod means extending transversely across the passage means downstream of the spray means, thereby forming a plurality of slits between the first rod means through which the gases may flow, means for rotating the first rod means 90*, so that the first rod means are parallel to the axis of the passage means, a plurality of second parallel, spaced, rod means extending transversely across the passage means downstream of the first rod means, thereby forming a plurality of slits between the second rod means through which the gases may flow, and means for rotating the second rod means 90*, so that the second rod means are parallel to the axis of the passage means.
Claim 5
Dependent Claim
146 words
In a wet scrubber for removing impurities from gases, passage means through which the gases flow, spray means for spraying a liquid into the passage means, a plurality of first parallel, spaced, rod means extending transversely across the passage means downstream of the spray means, thereby forming a plurality of slits between the first rod means through which the gases may flow, means for rotating the first rod means 90*, so that the first rod means are parallel to the axis of the passage means, a plurality of second parallel, spaced, rod means extending transversely across the passage means downstream of the first rod means, thereby forming a plurality of slits between the second rod means through which the gases may flow, and means for rotating the second rod means 90*, so that the second rod means are parallel to the axis of the passage means.
Claim 6
Dependent Claim
46 words
The wet scrubber set forth in claim 3, wherein the first rod means are of a different size than the second rod means, so that the slits between the first rod means have a different width than that of the slits between the second rod means.
