Abstract
Abstract An apparatus for treating particulate matter while in a fluidized state in a plurality of fluidized bed chambers. The apparatus has means for causing gas flow therethrough having an inlet and an outlet, and a plurality of treating units. Each treating unit includes a fluidized bed chamber having means for gas flow therethrough and into the inlet, a bypass for gas flow external to the fluidized chamber and into the inlet, and means for cooperatively regulating the flow of gas through the chamber and through the bypass into the inlet so that a substantially constant flow of gas is maintained thereinto from the treating unit. In this way the flow of gas through each unit is unaffected by operating conditions of other units of the apparatus. Further, the outlet from the gas flow means may be conveniently connected to suitable treating equipment for recovery of solvents and of solid particles included in effluents from the apparatus and for the performance of other operations thereon to render such effluents ecologically acceptable.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
198 words
A surge free apparatus for treating particulate matter in a fluidized state in a plurality of treating units each of which operates in a substantially independent manner, the apparatus comprising, means for causing a flow of gas having an inlet consisting essentially of a manifold having a plurality of intakes, and an outlet, and a plurality of treating units, each treating unit consisting essentially of a fluidized bed chamber having means for gas flow therethrough and into one of said intakes said chamber gas flow means including means disposed between the chamber outlet and said one intake for boosting flow of gas through said chamber to provide compensation means for pressure loss occurring when treating particulate matter in said fluidized bed chamber, means for bypass gas flow external to said chamber and into another of said intakes, and means for cooperatively regulating flow of gas through said chamber gas flow means and said bypass gas flow means so as to maintain a substantially constant flow of gas from said treating unit into said manifold, whereby, each of said treating units is substantially free of a surge of flow of gas regardless of operational status of other treating units.
Claim 2
Dependent Claim
198 words
A surge free apparatus for treating particulate matter in a fluidized state in a plurality of treating units each of which operates in a substantially independent manner, the apparatus comprising, means for causing a flow of gas having an inlet consisting essentially of a manifold having a plurality of intakes, and an outlet, and a plurality of treating units, each treating unit consisting essentially of a fluidized bed chamber having means for gas flow therethrough and into one of said intakes said chamber gas flow means including means disposed between the chamber outlet and said one intake for boosting flow of gas through said chamber to provide compensation means for pressure loss occurring when treating particulate matter in said fluidized bed chamber, means for bypass gas flow external to said chamber and into another of said intakes, and means for cooperatively regulating flow of gas through said chamber gas flow means and said bypass gas flow means so as to maintain a substantially constant flow of gas from said treating unit into said manifold, whereby, each of said treating units is substantially free of a surge of flow of gas regardless of operational status of other treating units.
Claim 3
Dependent Claim
198 words
A surge free apparatus for treating particulate matter in a fluidized state in a plurality of treating units each of which operates in a substantially independent manner, the apparatus comprising, means for causing a flow of gas having an inlet consisting essentially of a manifold having a plurality of intakes, and an outlet, and a plurality of treating units, each treating unit consisting essentially of a fluidized bed chamber having means for gas flow therethrough and into one of said intakes said chamber gas flow means including means disposed between the chamber outlet and said one intake for boosting flow of gas through said chamber to provide compensation means for pressure loss occurring when treating particulate matter in said fluidized bed chamber, means for bypass gas flow external to said chamber and into another of said intakes, and means for cooperatively regulating flow of gas through said chamber gas flow means and said bypass gas flow means so as to maintain a substantially constant flow of gas from said treating unit into said manifold, whereby, each of said treating units is substantially free of a surge of flow of gas regardless of operational status of other treating units.
Claim 4
Dependent Claim
198 words
A surge free apparatus for treating particulate matter in a fluidized state in a plurality of treating units each of which operates in a substantially independent manner, the apparatus comprising, means for causing a flow of gas having an inlet consisting essentially of a manifold having a plurality of intakes, and an outlet, and a plurality of treating units, each treating unit consisting essentially of a fluidized bed chamber having means for gas flow therethrough and into one of said intakes said chamber gas flow means including means disposed between the chamber outlet and said one intake for boosting flow of gas through said chamber to provide compensation means for pressure loss occurring when treating particulate matter in said fluidized bed chamber, means for bypass gas flow external to said chamber and into another of said intakes, and means for cooperatively regulating flow of gas through said chamber gas flow means and said bypass gas flow means so as to maintain a substantially constant flow of gas from said treating unit into said manifold, whereby, each of said treating units is substantially free of a surge of flow of gas regardless of operational status of other treating units.
Claim 5
Dependent Claim
56 words
An apparatus as set forth in claim 1 wherein said regulating means consists of valve means for controlling flow of gas in said chamber gas flow means, valve means for controlling flow of gas in said bypass gas flow means and means for cooperatively opening and closing said chamber valve means and said bypass value means.
