Claim 1
Independent Claim
222 words
An air scrubber comprising, a collection chamber, a surface means on which condensable contaminants in the discharge stream of a ventilating system can accumulate, gate means selectively to control the flow of the discharge stream through said collection chamber, a vaporizable solvent capable of dissolving contaminant materials from said surface means, discharge means to direct the vaporized solvent onto said surface means, a holding tank communicating with said collection chamber to receive and collect the solvent in which the contaminant materials are dissolved, a generating tank, first conduit means by which the contents in said holding tank may be discharged into said generating tank, flow control means operative with respect to said first conduit means selectively to discharge the contents of said holding tank into said generating tank, means to heat said generating tank in order to vaporize the solvent therein and separate it from the contaminant materials dissolved in the solvent, said contaminant materials remaining in said generating tank, second conduit means by which the vaporized solvent passes from said generating tank to said discharge means, an incinerator, third conduit means by which the contaminant materials in said generating tank may be discharged into said incinerator and flow control means operative with respect to said third conduit means selectively to discharge the contaminant materials in said generating tank into said incinerator.
Claim 2
Dependent Claim
222 words
An air scrubber comprising, a collection chamber, a surface means on which condensable contaminants in the discharge stream of a ventilating system can accumulate, gate means selectively to control the flow of the discharge stream through said collection chamber, a vaporizable solvent capable of dissolving contaminant materials from said surface means, discharge means to direct the vaporized solvent onto said surface means, a holding tank communicating with said collection chamber to receive and collect the solvent in which the contaminant materials are dissolved, a generating tank, first conduit means by which the contents in said holding tank may be discharged into said generating tank, flow control means operative with respect to said first conduit means selectively to discharge the contents of said holding tank into said generating tank, means to heat said generating tank in order to vaporize the solvent therein and separate it from the contaminant materials dissolved in the solvent, said contaminant materials remaining in said generating tank, second conduit means by which the vaporized solvent passes from said generating tank to said discharge means, an incinerator, third conduit means by which the contaminant materials in said generating tank may be discharged into said incinerator and flow control means operative with respect to said third conduit means selectively to discharge the contaminant materials in said generating tank into said incinerator.
Claim 3
Dependent Claim
59 words
An air scrubber, as set forth in claim 1, in which a reservoir is provided to replenish the supply of solvent in said generating tank, a fourth conduit means connecting said reservoir with a generating tank and metering means operative with respect to said fourth conduit means periodically to introduce a replenishing supply of solvent into said generating tank.
Claim 4
Dependent Claim
27 words
An air scrubber, as set forth in claim 1, in which said surface means further comprises a filter located in juxtaposition to a plurality of impingement members.
Claim 5
Dependent Claim
80 words
An air scrubber, as set forth in claim 1, further comprising first and second combustion areas in said incinerator means, wick means within said first combustion area to receive the contaminant materials, first burner means to ignite the flammable materials on said wick means and thereby emit products of combustion which pass into and through said secondary combustion area and second burner means to ignite any combustible materials included in the products of combustion emitted from said first combustion area.
