Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
211 words
AN APPARATUS FOR CONTINUOUSLY REACTING A REACTANT LIQUID WITH REACTANT FLUID, IN WHICH A FILM OF THE REACTING LIQUID IS CONTINUOUSLY FLOWED DOWNWARDLY ALONG ELONGATED REACTION SURFACE MEANS IN CONTACT WITH CONCURRENTLY FLOWING REACTANT FLUID, COMPRISING; A REACTOR COMPRISING TWO CONCENTRIC, VERTICALLY EXTENDING WALLS WHICH ARE RADIALLY SPACED FROM EACH OTHER TO DEFINE AN ANNULAR REACTION ZONE WITH THE OPPOSING SURFACES OF SAID WALLS DEFINING TWO OPPOSING REACTION SURFACES; AN ANNULAR NOZZLE DISPOSED BETWEEN SAID SURFACES FOR FEEDING SAID REACTANT FLUID TO THE UPPER END OF SAID REACTION ZONE; FEEDING MEANS FOR FEEDING SAID FLUID TO THE UPPER END OF SAID REACTION ZONE, SAID FEEDING MENS BEING SEPARATE FROM SAID NOZZLE, SAID FEEDING MEANS COMPRISING MEANS MOUNTED ON SAID REACTOR AND DEFINING A CHAMBER FOR CONTAINING SAID LIQUID, SAID CHAMBER BEING OPEN ALONG ONE SAID THEREOF ADJACENT TO THE UPPER END OF ONE OF SAID REACTION SURFACES, WOVEN NET MEANS EXTENDING COMPLETELY ACROSS THE OPEN SIDE OF SAID CHAMBER AND HAVING UNIFORMLY ARRANGED SMALL OPENINGS THERETHROUGH, SAID OPENINGS HAVING AN EFFECTIVE SIZE OF 5 TO 90 U, WHEREBY THE LIQUID PASSES FROM THE CHAMBER THROUGH SAID OPENINGS AND FLOWS ONTO THE UPPER PORTION OF ONE OF SAID REACTION SURFACES AND MOVES DOWNWARDLY THEREON AS A THIN FILM OF SUBSTANTIALLY UNIFORM THICKNESS.

Claim 3
Independent Claim
212 words
An apparatus for continuously reacting a reactant liquid with reactant fluid, in which a film of the reacting liquid is continuously flowed downwardly along elongated reaction surface means in contact with concurrently flowing reactant fluid, comprising; a reactor comprising two concentric, vertically extending walls which are radially spaced from each other to define an annular reaction zone with the opposing surfaces of said walls defining two opposing reaction surfaces; an annular nozzle disposed between said surfaces for feeding said reactant fluid to the upper end of said reaction zone; feeding means for feeding said liquid to the upper end of said reaction zone, said feeding means being separate from said nozzle, said feeding means comprising means mounted on said reactor and defining a chamber for containing said liquid, said chamber being open along one side thereof adjacent to the upper end of one of said reaction surfaces, woven net means extending completely across the open side of said chamber and having uniformly arranged small openings therethrough, said openings having an effective size of 5 to 90 Mu , whereby the liquid passes from the chamber through said openings and flows onto the upper portion of one of said reaction surfaces and moves downwardly thereon as a thin film of substantially uniform thickness.
Claim 4
Independent Claim
212 words
An apparatus for continuously reacting a reactant liquid with reactant fluid, in which a film of the reacting liquid is continuously flowed downwardly along elongated reaction surface means in contact with concurrently flowing reactant fluid, comprising; a reactor comprising two concentric, vertically extending walls which are radially spaced from each other to define an annular reaction zone with the opposing surfaces of said walls defining two opposing reaction surfaces; an annular nozzle disposed between said surfaces for feeding said reactant fluid to the upper end of said reaction zone; feeding means for feeding said liquid to the upper end of said reaction zone, said feeding means being separate from said nozzle, said feeding means comprising means mounted on said reactor and defining a chamber for containing said liquid, said chamber being open along one side thereof adjacent to the upper end of one of said reaction surfaces, woven net means extending completely across the open side of said chamber and having uniformly arranged small openings therethrough, said openings having an effective size of 5 to 90 Mu , whereby the liquid passes from the chamber through said openings and flows onto the upper portion of one of said reaction surfaces and moves downwardly thereon as a thin film of substantially uniform thickness.
Claim 5
Dependent Claim
31 words
An apparatus according to claim 1, in which said net means consists of a single net layer having openings of a size in the range of 5 to 90 Mu .
Claim 6
Dependent Claim
53 words
An apparatus according to claim 1, in which said net means consists of a plurality of superposed net layers having openingS of sizes such that they provide an effective flow corresponding to the flow through a single net layer having openings of a size in the range of 5 to 90 Mu .
Claim 7
Dependent Claim
102 words
An apparatus according to claim 1, in which said means defining said chamber comprises a casing mounted on the upper end of said reactor and having a conduit extending laterally outwardly from said chamber on the opposite side thereof from said one side thereof, a frame removably disposed in said chamber and sealingly contacting the wall of said chamber, said frame member being substantially channel-shaped and having an opening through the base wall thereof, the legs of said frame member projecting toward said one side of said chamber and said net means being disposed across the open side of said frame member.
Claim 8
Dependent Claim
30 words
An apparatus according to claim 1, wherein said net is made of filaments of stainless steel, iron, brass, titanium, aluminum, glass, asbestos, polyester, or polyamide or combinations of said filaments.
Claim 9
Dependent Claim
60 words
An apparatus according to claim 1, in which said chamber is disposed sidewardly from the upper end of one of said reaction surfaces, and said net means extends substantially vertically from the upper end of said one reaction surface and constitutes a vertical extension thereof, said net means having a vertical dimension in the range of 5 to 50 mm.
Claim 10
Dependent Claim
