Abstract
Abstract A centrifugal reactor comprising an enclosure having an inlet for directing a stream of waste reactant tangentially into the enclosure and forming a film moving in a downwardly spiraling path along the inner wall surfaces of the enclosure. A second waste reactant is fed through the top of the enclosure into a sparger which directs such second waste reactant as a spray against the spirally moving film at substantially right angles thereto effecting a complete blending and neutralization of the two waste reactants.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
90 words
A reactor comprising: an enclosure having an upper portion and a lower portion terminating in a reduced diameter portion defining an outlet, said upper and lower portions having inner wall surfaces, means for admitting a stream of reactant under pressure tangentially into said upper portion causing said reactant to form a film moving in a spiral path downwardly along said inner wall surfaces, means for introducing a second reactant radially under pressure into said enclosure as a spray against said moving film of first reactant at substantially right angles thereto.
Claim 2
Dependent Claim
90 words
A reactor comprising: an enclosure having an upper portion and a lower portion terminating in a reduced diameter portion defining an outlet, said upper and lower portions having inner wall surfaces, means for admitting a stream of reactant under pressure tangentially into said upper portion causing said reactant to form a film moving in a spiral path downwardly along said inner wall surfaces, means for introducing a second reactant radially under pressure into said enclosure as a spray against said moving film of first reactant at substantially right angles thereto.
Claim 3
Dependent Claim
55 words
A reactor according to claim 1 wherein said first mentioned means comprises a first conduit connected tangentially to said upper portion, and said last mentioned means comprises a second conduit within said enclosure in radially spaced relation to said inner wall surfaces and having a plurality of circumferentially spaced openings disposed below said first conduit.
Claim 4
Dependent Claim
23 words
A reactor according to claim 2 including a closure member on the inner end of said second conduit below said circumferentially spaced openings.
Claim 5
Dependent Claim
36 words
A reactor according to claim 1 wherein said upper portion is cylindrical in shape and Said lower portion extends downwardly from said cylindrical upper portion and has a truncated conical configuration tapering downwardly to said outlet.
Claim 6
Dependent Claim
23 words
A reactor as defined in claim 1 wherein said first reactant is a liquid waste product and said second reactant is a gas.
Claim 7
Dependent Claim
33 words
A reactor according to claim 1 wherein said last mentioned means includes a conduit within said enclosure having a closed end and a plurality of circumferentially spaced openings for discharging said second reactant.
Claim 8
Dependent Claim
170 words
A reactor comprising: an enclosure having an upper portion and a lower portion terminating in a reduced diameter portion defining an outlet, said upper and lower portions having inner wall surfaces, means for admitting a stream of reactant under pressure tangentially into said upper portion causing said reactant to form a film moving in a spiral path downwardly along said inner wall surfaces, means for introducing a second reactant radially under pressure into said enclosure as a spray against said moving film of first reactant at substantially right angles thereto, said first mentioned means comprising a first conduit connected tangentially to said upper portion, said last mentioned means comprising a second conduit within said enclosure in radially spaced relation to said inner wall surfaces and having a plurality of circumferentially spaced openings disposed below said first conduit, said enclosure upper portion having an end wall, a hollow tube extending through said end wall into said enclosure between said inner wall surfaces and said second conduit in radially spaced relation thereto.
Claim 9
Dependent Claim
170 words
A reactor comprising: an enclosure having an upper portion and a lower portion terminating in a reduced diameter portion defining an outlet, said upper and lower portions having inner wall surfaces, means for admitting a stream of reactant under pressure tangentially into said upper portion causing said reactant to form a film moving in a spiral path downwardly along said inner wall surfaces, means for introducing a second reactant radially under pressure into said enclosure as a spray against said moving film of first reactant at substantially right angles thereto, said first mentioned means comprising a first conduit connected tangentially to said upper portion, said last mentioned means comprising a second conduit within said enclosure in radially spaced relation to said inner wall surfaces and having a plurality of circumferentially spaced openings disposed below said first conduit, said enclosure upper portion having an end wall, a hollow tube extending through said end wall into said enclosure between said inner wall surfaces and said second conduit in radially spaced relation thereto.
Claim 10
Dependent Claim
29 words
A reactor according to claim 1 wherein said tube has one end projecting axially outwardly from said end wall and provided with connecting means attachable to a supporting structure.
Claim 11
Dependent Claim
33 words
A reactor according to claim 8 wherein said other end of said tube terminates in an end portion disposed below said first conduit and above said circumferentially spaced openings of said second conduit.
Claim 12
Dependent Claim
35 words
A reactor according to claim 8 wherein said second conduit is rigidly secured at the outer end thereof to an annular flange forming a closure for said tube and attachable to said tube connecting means.
