Claims27
An apparatus for producing a fluid jet stream comprising solid particulates, said apparatus comprising:
- a central pressurized fluid chamber aligned with a central axis capable of withstanding fluid pressures of from about 10 psi to about 60,000 psi;
- fluid inlet means at one end of said pressurized fluid chamber;
- at least one discontinuity generator means positioned at the other, downstream end of said pressurized fluid chamber;
- fluid orifice means having at least one fluid orifice said fluid oribise using aligned with said central axis and downstream from and immediately adjacent said discontinuity generator means;
- particulate inlet means comprising at least one particulate orifice positioned at an angle to said central axis and peripheral to said fluid orifice means;
- a mixing chamber in communication with said fluid orifice means and said particulate inlet means wherein said particulates are introduced and mixed with said fluid jet stream;
- and a flow shaping cone having a tapered central passage in communication with said mixing chamber positioned for passage of said fluid jet stream comprising solid particulates.
A process for producing a fluid jet stream comprising solid particulates, comprising the sequential steps of:
- passing a pressurized fluid jet stream at pressures of from about 10 psi to about 60,000 psi through a pressurized fluid chamber aligned with a central axis;
- intercepting the path of said pressurized fluid jet stream with at least one discontinuity generator means thereby creating fluid instabilities and turbulence in said fluid jet stream;
- passing said turbulent fluid jet stream through at least one fluid orifice means having at least one fluid orifice aligned with said central axis and immediately adjacent said discontinuity generator means;
- introducing said solid particulates peripherally to said fluid orifice means and at an angle to said central axis and mixing said particulates with said fluid jet stream;
- passing said fluid jet stream comprising solid particulates through a flow shaping cone.
In a process for producing a fluid jet stream comprising the steps of passing a pressurized fluid jet stream at pressures of about 10 psi to about 60,000 psi through a pressurized fluid chamber, passing said fluid jet stream through at least one fluid orifice means having at least one fluid orifice and introducing and mixing solid particulates with said fluid jet stream, the improvement comprising:
- intercepting the path of said pressurized fluid jet stream with at least one discontinuity generator means immediately prior to passage of said fluid jet stream through said at least one fluid orifice, thereby creating fluid instabilities and turbulence in said fluid jet stream and passing said turbulent fluid jet stream through said orifice means before said fluid instabilities and turbulence have dissipated or become reduced.
In an apparatus for entraining solid particulates in a fluid jet stream of the type comprising a central pressurized fluid chamber, fluid inlet means at one end of said pressurized fluid chamber, fluid orifice means having at least one fluid orifice at the other end of said pressurized fluid chamber, particulate inlet means positioned peripherally to said fluid orifice means, a mixing chamber in communication with said fluid orifice means and said particulate inlet means, and a flow shaping cone having a tapered central passage positioned for passage of said fluid jet stream with entrained particulates, the improvement comprising at least one discontinuity generator means positioned in said pressurized fluid chamber upstream from and immediately adjacent said fluid orifice.
