초록 ▼

An oil in water emulsion is prepared as a continuous process by causing a stream of water to flow through a duct containing a Venturi providing a converging frustum of a cone zone, a diverging frustum of a cone zone and a central zone joining the two frustum of a cone zones, so that the stream flows through a zone upstream of the Venturi where it is directed along a helicoidal path through the converging frustum of a cone zone to the central zone, drawing oil for emulsification to the duct at the zone upstream of the Venturi and causing it to flow along a helicoidal path in the same direction as the water to the central zone so that the oil and water mix and emulsify in that central zone, causing the emulsion so formed to flow through the diverging frustum of a cone zone, then causing the emulsion to flow along a helicoidal path of reverse slope, and thereafter discharging the emulsion from the duct.

The method of preparing an oil and water emulsion as a continuous process which comprises, feeding a stream of water to a duct containing a Venturi providing a converging frustum of a cone zone, a diverging frustum of a cone zone and a central zone joining the two frustum of a cone zones, causing the stream to flow through a zone located upstream of the Venturi and having means for causing the stream to flow along a first helicoidal path through the converging frustum of a cone zone to said central zone, drawing oil for emulsification to the duct at a point adjacent said zone upstream of the Venturi and causing said oil to flow along a helicoidal path in the same direction as said first helicoidal path so that the oil and water mix and emulsify in said central zone, causing the emulsion so formed to flow through the diverging frustum of a cone zone, then causing said emulsion to flow along a second helicoidal path whose slope is the reverse of the slope of the first helicoidal path, and thereafter discharging the emulsion from said duct. Apparatus for the preparation of a water and oil emulsion as a continuous process comprising, a duct containing a Venturi providing a converging frustum of a cone surface, a diverging frustum of a cone surface and a throat, a tube mounted for adjustable sliding movement in said duct upstream of the Venturi, a frustum of a cone nozzle mounted on the downstream end of the tube to direct a stream of water into said throat and having an external surface parallel to said converging frustum of a cone surface and provided with involuted grooves, said duct having an annular chamber surrounding the lower portion of said tube and communicating with said grooves and with said throat, an oil supply pipe communicating with said chamber, a helicoidally wound strip mounted in said tube with its axis parallel to the tube axis, adapted to direct the water to flow from the nozzle along a first helicoidal path, and means located in the tube downstream of the Venturi adapted to direct the emulsion to flow along a second helicoidal path whose slope is opposite to the direction of slope of the first helicoidal path.
