Abstract
Abstract An apparatus for preparing dispersions comprising a closed casing in the form of a bottomed hollow cylinder, a rotor disposed within the casing coaxially therewith and having a multiplicity of hard wire projections on the peripheral wall of the rotor, at least one liquid inlet pipe connected to one end of the casing, a dispersion outlet pipe connected to the other end of the casing and drive means disposed outside the casing at one side thereof for rotating the rotor at a high speed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
90 words
A method for reforming high molecular weight fuel oils, comprising the steps of introducing a high molecular weight fuel oil selected from the group consisting of heavy oil, waste oil, animal oil and vegetable oil, and water in a proportion of 10 to 30 vol. % based on the fuel oil into a casing, and dispersing the water in the fuel oil in the form of ultrafine particles by rotating a rotor having a number of hard wire projections at a speed of 1600 to 3600 r.p.m. in the casing.
Claim 2
Independent Claim
90 words
A method for reforming high molecular weight fuel oils, comprising the steps of introducing a high molecular weight fuel oil selected from the group consisting of heavy oil, waste oil, animal oil and vegetable oil, and water in a proportion of 10 to 30 vol. % based on the fuel oil into a casing, and dispersing the water in the fuel oil in the form of ultrafine particles by rotating a rotor having a number of hard wire projections at a speed of 1600 to 3600 r.p.m. in the casing.
Claim 3
Dependent Claim
43 words
A method as defined in claim 1, further comprising the steps of introducing a gas selected from the group consisting of air and an oxygen-containing gas into the casing in an amount of 1 to 5 vol. % based on the fuel oil.
Claim 4
Independent Claim
192 words
An apparatus for reforming high molecular weight fuel oils comprising a closed casing defining a central axis, and having the form of a hollow cylinder having a diameter of 100 to 250 mm, a first inlet pipe communicating with said casing for introducing thereinto a high molecular weight fuel oil selected from the group consisting of heavy oil, waste oil, animal oil and vegetable oil, said fuel oil being reformed in said casing, a second inlet pipe communicating with said casing for introducing water at one end of said casing, an outlet pipe communicating with said casing for discharging the reformed fuel oil at the other end of said casing, a rotor disposed coaxially within said casing and provided with a multiplicity of slender hard wire projections having a diameter of 0.5 to 1.2 mm, a length of 20 to 35 mm, and arranged as a helical assembly, a clearance ranging from 1 mm to 5 mm existing between an inner peripheral wall surface of said casing and outward ends of said projections, and drive means for rotating said rotor at a high speed disposed outside said casing at one side thereof.
Claim 5
Independent Claim
192 words
An apparatus for reforming high molecular weight fuel oils comprising a closed casing defining a central axis, and having the form of a hollow cylinder having a diameter of 100 to 250 mm, a first inlet pipe communicating with said casing for introducing thereinto a high molecular weight fuel oil selected from the group consisting of heavy oil, waste oil, animal oil and vegetable oil, said fuel oil being reformed in said casing, a second inlet pipe communicating with said casing for introducing water at one end of said casing, an outlet pipe communicating with said casing for discharging the reformed fuel oil at the other end of said casing, a rotor disposed coaxially within said casing and provided with a multiplicity of slender hard wire projections having a diameter of 0.5 to 1.2 mm, a length of 20 to 35 mm, and arranged as a helical assembly, a clearance ranging from 1 mm to 5 mm existing between an inner peripheral wall surface of said casing and outward ends of said projections, and drive means for rotating said rotor at a high speed disposed outside said casing at one side thereof.
Claim 6
Dependent Claim
84 words
An apparatus as defined in claim 3, wherein the casing has a diameter of 150 to 200 mm, the hard wire projections have a diameter of 0.5 to 1.0 mm and a length of 27 to 33 mm, the clearance between the inner peripheral wall of the casing and the forward ends of the projections being 1 to 3 mm, the projections being operatively rotated at a speed of 20 to 50 m/sec. in the mixture of the fuel oil and of the water.
