Abstract
The present invention relates to a method of cleaning solids to be free of, or separating solids from, viscous materials and in some cases other solids such as, but not limited to resins and other coatings, foreign debris, clays, silts, contaminated water or chemicals and in other cases separating some liquids form some other liquids. Also disclosed are systems to accomplish such.
Claims19
A method of cleaning contaminated solid particles comprising the steps of:
- creating a slurry comprising waste material comprising contaminated solid particles by mixing said waste material with a liquid;
- passing the aqueous slurry of material and water through a venturi inductor which uses pressurized water flow to re-suspend and blend the slurry to a desired density, pressure, velocity, temperature and/or other parameters prior to introduction into the high velocity accelerator;
- introducing said slurry into an entry port located at a first extremity of a high velocity accelerator, where said high velocity accelerator is adapted to impart an increase in the velocity of the material introduced therein;
- processing the slurry in said high velocity accelerator;
- by rapidly expanding the volume of said slurry introduced into the high velocity accelerator without diminishing the velocity thereof;
- imparting a rapid acceleration at an angle to the slurry of solid and liquid materials to displace said slurry in a concentric path towards an outflow port situated at one extremity of an internal chamber of the high velocity accelerator;
- and
- focusing the slurry at a focal point to promote interparticle collisions.

A method of removing oil contaminants on solid particulates comprising the steps of:
- using a liquid to create a slurry of the contaminated solids;
- processing the slurry in a high velocity accelerator:
- by rapidly expanding the volume of said slurry introduced into the high velocity accelerator without diminishing the velocity thereof;
- imparting a rapid acceleration at an angle to the slurry stream of solid and liquid materials to displace said slurry stream in a concentric path towards an outflow port situated at one extremity of an internal chamber of the high velocity accelerator;
- and
- focusing the slurry stream at a focal point to promote interparticle collisions;
- which said interparticle collisions cause a separation of particulates and oil contaminant and further result of dissimilar liquid separation and dissimilar particulate separation through the induction of a state where liquids vaporize;
- separating solid particulates from other components in the liquid flow;
- and
- a series of separation modules which receives the output of the apparatus and separates solids, liquids and gases according to their density.

A method of removing oil contaminants on contaminated solid particulates comprising the steps of:
- a) using water at a temperature below standard hot water extraction process temperature to create an aqueous slurry of the contaminated solids;
- b) processing the slurry in a high velocity accelerator:
- by rapidly expanding the volume of said slurry introduced into the high velocity accelerator without diminishing the velocity thereof;
- imparting a rapid acceleration at an angle to the slurry stream of solid and liquid materials to displace said slurry stream in a concentric path towards an outflow port situated at one extremity of an internal chamber of the high velocity accelerator;
- and
- focusing the slurry stream at a focal point to promote interparticle collisions;
- which said interparticle collisions cause a separation of particulates and oil contaminant;
- c) separating solid particles from other components in the resulting output liquid flow;
- and
- d) separating the output liquid flow of the high velocity accelerator into liquid and gas streams according to their density.
