Device for removing noxious matter from exhaust gases

Claim 1

A device for removing noxious matter from a stream of heated gases comprising: A. means defining an elongated chamber having a plurality of ported partitions supported in axially spaced relation for defining therebetween a plurality of axially aligned compartments, and means defining a sump disposed beneath said plurality of compartments, adapted to confine a body of water; B. means for introducing a stream of heated gases into said chamber including a gas conduit having one end thereof connected with a source of heated gases and the opposite end thereof connected with said elongated chamber; C. means for scrubbing and cooling the gases of said stream with water particles comprisIng, 1. initial scrubbing means including means defining within said conduit a venturi throat having one end thereof disposed adjacent to said chamber, means defining within the throat of circumscribing, axially directed port, means defining in circumscribing relation with said port a plenum chamber, and a tubular conduit extended between said plenum chamber and said sump adapted to deliver a stream of water from the sump to the plenum chamber as low pressure is introduced into said plenum chamber in response to a passage of heated gases through said throat, whereby an annular jet of water particles is drawn through said port into said stream of gases, and 2. final scrubbing means including a spray head mounted in said chamber in axially spaced relation with said throat for injecting a transversely oriented stream of water particles into said stream of gases, and means including a tubular conduit connected with said spray head adapted to deliver a pressurized stream of water to said head; D. filter packing disposed within selected compartments of said plurality of compartments for filtering particulate matter from said stream of gas; and E. means defining within each of said compartments a plurality of ports through which the compartments communicate with said sump.

Claim 2

A device for removing noxious matter from a stream of heated gases comprising: A. means defining an elongated chamber having a plurality of ported partitions supported in axially spaced relation for defining therebetween a plurality of axially aligned compartments, and means defining a sump disposed beneath said plurality of compartments, adapted to confine a body of water; B. means for introducing a stream of heated gases into said chamber including a gas conduit having one end thereof connected with a source of heated gases and the opposite end thereof connected with said elongated chamber; C. means for scrubbing and cooling the gases of said stream with water particles comprisIng, 1. initial scrubbing means including means defining within said conduit a venturi throat having one end thereof disposed adjacent to said chamber, means defining within the throat of circumscribing, axially directed port, means defining in circumscribing relation with said port a plenum chamber, and a tubular conduit extended between said plenum chamber and said sump adapted to deliver a stream of water from the sump to the plenum chamber as low pressure is introduced into said plenum chamber in response to a passage of heated gases through said throat, whereby an annular jet of water particles is drawn through said port into said stream of gases, and 2. final scrubbing means including a spray head mounted in said chamber in axially spaced relation with said throat for injecting a transversely oriented stream of water particles into said stream of gases, and means including a tubular conduit connected with said spray head adapted to deliver a pressurized stream of water to said head; D. filter packing disposed within selected compartments of said plurality of compartments for filtering particulate matter from said stream of gas; and E. means defining within each of said compartments a plurality of ports through which the compartments communicate with said sump.
