Abstract
Abstract A method and apparatus for dispersing one liquid of two mutually insoluble liquids into the other liquid or dispersing a pulverized solid powder into a liquid, wherein a mixture of the two liquids to be dispersed or a mixture of liquids containing pulverized solid powder to be dispersed is jetted through a single or a plurality of unit dispersers to a relatively wider gap portion than a nozzle to impinge upon wall surfaces to change the direction of the liquid flow.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
112 words
In a process for dispersing one liquid of two mutually insoluble liquids into the other liquid or dispersing a pulverized solid powder into a liquid comprising carrying out the following process successively a plurality of times in a continuous series: jetting a mixture of said liquids or said liquid and said solid from a nozzle into a relatively wider gap portion than said nozzle to impinge the mixture upon a wall surface of a magazine containing a plurality of openings thereby changing the liquid flow direction, passing said mixture into said openings and carrying said mixture through said magazine to the feed for the nozzle of the next stage in the series.
Claim 2
Dependent Claim
112 words
In a process for dispersing one liquid of two mutually insoluble liquids into the other liquid or dispersing a pulverized solid powder into a liquid comprising carrying out the following process successively a plurality of times in a continuous series: jetting a mixture of said liquids or said liquid and said solid from a nozzle into a relatively wider gap portion than said nozzle to impinge the mixture upon a wall surface of a magazine containing a plurality of openings thereby changing the liquid flow direction, passing said mixture into said openings and carrying said mixture through said magazine to the feed for the nozzle of the next stage in the series.
Claim 3
Dependent Claim
46 words
The process of claim 1, wherein the time of dispersing of the entire process is for a period of time of from about 1/10,000 to about 1/50 second and the pressure loss through a stage of the whole process is more than about 10kg/cm 2 .
Claim 4
Dependent Claim
89 words
A dispersion device for dispersing one liquid of two mutually insoluble liquids into the other liquid or dispersing a pulverized solid powder into a liquid, including a plurality of unit dispersers, each unit disperser which comprises a nozzle having blast nozzles therein for jetting a liquid, means forming a gap portion connected to said nozzle into which said liquid is jetted, and means forming one or more openings in a position different from that of said blast nozzles in said nozzle leading to the nozzle of the next unit.
Claim 5
Dependent Claim
89 words
A dispersion device for dispersing one liquid of two mutually insoluble liquids into the other liquid or dispersing a pulverized solid powder into a liquid, including a plurality of unit dispersers, each unit disperser which comprises a nozzle having blast nozzles therein for jetting a liquid, means forming a gap portion connected to said nozzle into which said liquid is jetted, and means forming one or more openings in a position different from that of said blast nozzles in said nozzle leading to the nozzle of the next unit.
