Abstract
Abstract A method, apparatus and system for separating particulate matter from gases laden therewith and for accumulating the particulate matter including apparatus for separating the particulate matter from the gases. The gas-particulate matter separating apparatus comprises means forming a first chamber adapted to receive a quantity of separating liquid having a predetermined specific gravity and having a gas inlet port in an upper portion thereof; means forming a second chamber adapted to receive a quantity of said separating liquid and having a gas exit port in an upper portion thereof; means forming a liquid conveyor passage communicating an intermediate portion of said first chamber with an intermediate portion of said second chamber; a sludge discharge port communicating with the lower portion of said second chamber; and conveyor means operative to mix particulate matter and gases entering said first chamber through said gas inlet port with liquid in said first chamber and to convey said mixture through said liquid conveyor passage into said second chamber wherein the gases and particulate matter are gravity separated with the gases exiting through said gas exit port and the particulate matter precipitating toward the bottom of said second chamber and toward said sludge discharge port.

Total Claims: 9
Claim 1
Independent Claim
202 words
Apparatus for cleaning dust laden air comprising, in combination: a container means for receiving a body of separating liquid, said container means including a first, second and third compartment with said third compartment intermediate said first and second compartments, said first compartment beinG enclosed relative to said second compartment above the liquid surface level, and adapted to receive dust laden air; a conveyor means enclosed within a pipe means extending intermediate said first and second compartments, said pipe means opening to said first compartment and to said second compartment, the conveyor means being adapted to draw dust laden air and liquid from said first compartment and to pump aid resultant mixture of air, liquid and dust to within said second compartment; an air exit portal extending from the container means for passing air from said second compartment; first aperture means extending intermediate said first compartment and third compartment to permit passage of separating liquid and sludge intermediate said first and third compartments; second aperture means extending intermediate said second and third compartments to permit passage of separating liquid and sludge intermediate said second and third compartments; and a sludge outlet portal about the container means for passing sludge from said second compartment.

Apparatus for cleaning dust laden air comprising, in combination: a container means for receiving a body of separating liquid, said container means including a first, second and third compartment with said third compartment intermediate said first and second compartments, said first compartment beinG enclosed relative to said second compartment above the liquid surface level, and adapted to receive dust laden air; a conveyor means enclosed within a pipe means extending intermediate said first and second compartments, said pipe means opening to said first compartment and to said second compartment, the conveyor means being adapted to draw dust laden air and liquid from said first compartment and to pump aid resultant mixture of air, liquid and dust to within said second compartment; an air exit portal extending from the container means for passing air from said second compartment; first aperture means extending intermediate said first compartment and third compartment to permit passage of separating liquid and sludge intermediate said first and third compartments; second aperture means extending intermediate said second and third compartments to permit passage of separating liquid and sludge intermediate said second and third compartments; and a sludge outlet portal about the container means for passing sludge from said second compartment.
Claim 3
Dependent Claim
36 words
The apparatus of claim 1 in which the conveyor means is in the form of a conveyor screw extending intermediate said first and second compartments; and including drive means for imparting motion to said conveyor means.
Claim 4
Dependent Claim
51 words
The apparatus of claim 1 in which the sludge outlet portal is positioned at a gravitational level lower than the opening of said conveyor means at said second compartment; and the tank means includes a tapered bottom wall tapered from said second compartment at an angle towards the sludge outlet portal.
Claim 5
Dependent Claim
33 words
The apparatus of claim 3 in which the container means includes a first partition wall separating said first and said third compartments and a second partition wall separating said second and third compartments.
Claim 6
Dependent Claim
70 words
The apparatus of claim 4 in which said second aperture means is in the form of apertures within said second partition wall at a gravitational level lower than the opening of said conveyor means at said second compartment; and said first aperture means is in the form of apertures within said first partition wall at a gravitational level lower than the opening of said conveyor means at said first compartment.
Claim 7
Dependent Claim
20 words
The apparatus of claim 5 in which the sludge outlet portal opens within said first compartment about said bottom wall.
Claim 8
Independent Claim
282 words
A system for cleaning dust laden air of dust particles and accumulating the dust particles, the system comprising, in combination: a container means for receiving a body of separating liquid, said container means including at least a first, second and third compartment, said first compartment including an air input portal for receiving dust laden air; a conveyor means within said second compartment and extending intermediate said first and third compartments, said conveyor means opening to said first compartment and to said third compartment, the conveyor means being adapted to draw dust laden air and liquid from said first compartment and to deliver said resultant sludge and air to within said third compartment; an air exit portal extending to said third compartment for passing air from said third compartment; a sludge outlet portal about the bottom of the tank means for passing sludge from said third compartment; means forming a sludge passage extending from the sludge outlet portal for directing passage of sludge from said sludge outlet portal; a sludge settling vat engaged to said sludge passage to receive sludge from the sludge passage, the sludge settling vat being adapted to receive a supply of separating liquid; piping means for removing liquid from the settling tank and directing said removed liquid to the container means; pump means engaged with said piping means to increase the pressure of the liquid removed from the settling vat; interconnect means interconnecting said piping means and said passage means adjacent to the sludge outlet portal, said Interconnect means being positioned to direct at least a portion of said liquid within said passage means towards the sludge settling vat; sludge removal means for removing sludge from the settling vat.
