Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
A cyclone separator comprising elements, designed, sized and arranged for use in the separation of multi-phase liquids such as oil/water for separating a more dense component from a less dense component thereof, the separator comprising: (a) an elongated separating chamber having a longitudinal axis of symmetry between opposite first and second ends, the separating chamber being of greater cross-sectional dimension at the first end than at the second end, the separating chamber having an overflow outlet and at least one underflow outlet; and (b) at least one tangentially directed feed inlet proximate to the first end and disposed in a plane containing a secondary axis which extends from the longitudinal axis in a direction normal thereto and means for precluding shear planes and stagnation flows including a profile of said separating chamber which is at least in part of generally exponential form.
Claim 2
Dependent Claim
142 words
A cyclone separator comprising elements, designed, sized and arranged for use in the separation of multi-phase liquids such as oil/water for separating a more dense component from a less dense component thereof, the separator comprising: (a) an elongated separating chamber having a longitudinal axis of symmetry between opposite first and second ends, the separating chamber being of greater cross-sectional dimension at the first end than at the second end, the separating chamber having an overflow outlet and at least one underflow outlet; and (b) at least one tangentially directed feed inlet proximate to the first end and disposed in a plane containing a secondary axis which extends from the longitudinal axis in a direction normal thereto and means for precluding shear planes and stagnation flows including a profile of said separating chamber which is at least in part of generally exponential form.
Claim 3
Dependent Claim
142 words
A cyclone separator comprising elements, designed, sized and arranged for use in the separation of multi-phase liquids such as oil/water for separating a more dense component from a less dense component thereof, the separator comprising: (a) an elongated separating chamber having a longitudinal axis of symmetry between opposite first and second ends, the separating chamber being of greater cross-section dimension at the first end than at the second end, the separating chamber having an overflow outlet and at least one underflow outlet; and (b) at least one tangentially directed feed inlet proximate to the first end and disposed in a plane containing a secondary axis which extends from the longitudinal axis in a direction normal thereto, and means for precluding shear planes and stagnation flows including a profile of said separating chamber which is at least in part of generally cubic form.
Claim 4
Dependent Claim
142 words
A cyclone separator comprising elements, designed, sized and arranged for use in the separation of multi-phase liquids such as oil/water for separating a more dense component from a less dense component thereof, the separator comprising: (a) an elongated separating chamber having a longitudinal axis of symmetry between opposite first and second ends, the separating chamber being of greater cross-section dimension at the first end than at the second end, the separating chamber having an overflow outlet and at least one underflow outlet; and (b) at least one tangentially directed feed inlet proximate to the first end and disposed in a plane containing a secondary axis which extends from the longitudinal axis in a direction normal thereto, and means for precluding shear planes and stagnation flows including a profile of said separating chamber which is at least in part of generally cubic form.
Claim 5
Dependent Claim
44 words
A cyclone separator according to claim 1 characterized in that said profile meets the following requirement: r(mm)=6+22e.sup.(-z.spsp.1/2.sup./20) where r=radius of the separating chamber z=a measurement taken from a point in the plane of or spaced downstream of the point in a direction downstream thereof.
Claim 6
Dependent Claim
19 words
A cyclone separator according to claim 2 characterized in that said profile meets the following requirement: r(mm)=28-[z(2z.sup.2 ×10.sup.-6 +5)].sup.1/3.
Claim 7
Dependent Claim
27 words
A cyclone separator according to claim 1, characterized in that said overflow outlet is at said first end and said underflow outlet is at said second end.
Claim 8
Dependent Claim
22 words
A cyclone separator according to claim 1 characterized by said separating chamber including a swirl chamber section at the upstream end thereof.
Claim 9
Dependent Claim
19 words
A cyclone separator according to claim 6 characterized in that said swirl chamber section is substantially cylindrical in cross-section.
Claim 10
Dependent Claim
27 words
A cyclone separator according to claim 2, characterized in that said overflow outlet is at said first end and said underflow outlet is at said second end.
Claim 11
Dependent Claim
22 words
A cyclone separator according to claim 2, characterized by said separating chamber including a swirl chamber section at the upstream end thereof.
