Abstract
Abstract The recovery apparatus includes a collector device which may be connected to the exhaust flue or a furnace or disposed in a relatively confined area for collecting the exhaust gases or surrounding contaminated air. The collector device is connected by a conduit to a suction-blower device which may be comprised of two suction-blowers disposed in parallel for reliability. A pair of liquid filled tanks are provided and conduits are connected at one end to the suction-blower device with the opposite ends being disposed beneath the surface of the liquid. The process involves drawing the exhaust gases or contaminated air into the collector device by means of the suction-blower device and bubbling the exhaust gases or contaminated air through the liquid in the tank to remove all contaminates therefrom.

Claim 1
Independent Claim
318 words
An emission control device for removing contaminates from exhaust gases emitted from an exhaust pipe comprising collector means for collecting the contaminated exhaust gases, said collector means comprising inner and outer spaced apart frustoconical walls defining a continuous frusto-conical annular chamber and a central chamber defining an inlet at the wider end, spaced end wall means secured to said inner and said outer walls to close said annular chamber, means for securing the end of said collector means adjacent the wider end of the frusto-conical walls to an exhaust pipe whereby exhaust gases from the exhaust pipe may be introduced into said central chamber through said inlet, said inner wall being formed with two sets of vertically spaced elongated parallel horizontally disposed slots with the slots of one set being disposed diametrically opposite and intermediate the slots of the other set, Spaced flat baffle means secured to the inner wall along the top edge of each of said slots extending downwardly and inwardly in said central chamber for deflecting particulate contaminates toward said slots, said flat baffle means each extending more than half-way cross the diameter of said central chamber so that said baffle means adjacent each set of slots overlap each other, outlet means extending through said end wall means at the wider end of the frusto-conical walls, pipe means connected to said outlet means, exhaust blower means connected to said pipe means, liquid container means and additional pipe means connected at one end to said blower means and extending into said liquid container means so that it may be normally disposed beneath the level of the liquid when the container is filled with liquid to a predetermined level whereby said exhaust blower means will draw the contaminated gases from said central chamber, through said slots and said frusto-conical annular chamber and blow the contaminated exhaust gases through the liquid in the container to remove the contaminates.

An emission control device for removing contaminates from exhaust gases emitted from an exhaust pipe comprising collector means for collecting the contaminated exhaust gases, said collector means comprising inner and outer spaced apart frustoconical walls defining a continuous frusto-conical annular chamber and a central chamber defining an inlet at the wider end, spaced end wall means secured to said inner and said outer walls to close said annular chamber, means for securing the end of said collector means adjacent the wider end of the frusto-conical walls to an exhaust pipe whereby exhaust gases from the exhaust pipe may be introduced into said central chamber through said inlet, said inner wall being formed with two sets of vertically spaced elongated parallel horizontally disposed slots with the slots of one set being disposed diametrically opposite and intermediate the slots of the other set, Spaced flat baffle means secured to the inner wall along the top edge of each of said slots extending downwardly and inwardly in said central chamber for deflecting particulate contaminates toward said slots, said flat baffle means each extending more than half-way cross the diameter of said central chamber so that said baffle means adjacent each set of slots overlap each other, outlet means extending through said end wall means at the wider end of the frusto-conical walls, pipe means connected to said outlet means, exhaust blower means connected to said pipe means, liquid container means and additional pipe means connected at one end to said blower means and extending into said liquid container means so that it may be normally disposed beneath the level of the liquid when the container is filled with liquid to a predetermined level whereby said exhaust blower means will draw the contaminated gases from said central chamber, through said slots and said frusto-conical annular chamber and blow the contaminated exhaust gases through the liquid in the container to remove the contaminates.
Claim 3
Dependent Claim
51 words
An emission control device as set forth in claim 1 wherein said pipe means is comprised of two pipes connected to said outlet means at opposite sides of said annular chamber and a third pipe connected to said blower means at one end to said two pipes at the other end.
Claim 4
Dependent Claim
80 words
An emission control device as set forth in claim 1 wherein said liquid container means is comprised of two containers and wherein said additional pipe means is comprised of two separate pipes each of which may be normally disposed with the free end thereof beneath the level of the liquid when the containers are filled with liquid to a predetermined level and valve means associated with each of said two pipes for controlling the flow of gases to said containers.
Claim 5
Dependent Claim
167 words
An emission control device for removing contaminates from exhaust gases emitted from an exhaust pipe comprising contaminated air collecting means, suction-blower means, first conduit means connecting said collecting means to the suction side of said suction-blower means, liquid container means, second conduit means connected at one end to the blower side of said suction-blower means with the other end thereof disposed in said container means at a level below the ordinary liquid level when said container means is filled with liquid, said suction-blower means being comprised of two suction-blower units connected in parallel between said first and second conduit means and valve means in said conduits for selectively controlling the flow of air through said units, and said liquid container means being comprised of at least two liquid containers and said second conduit means is provided with at least two branch conduits each leading to a liquid container and further comprising valve means in said branch conduits to selectively control the flow of air to said containers.
Claim 6
Dependent Claim
167 words
