Abstract:
1. A hydrocyclone comprising: a first segment comprising a fluid inlet, an overflow outlet and a single spiral fluid ramp having a first end and a second end, said first end of said single spiral fluid ramp being in fluid communication with and extending from said fluid inlet; a second segment comprising a frustoconical segment having a wider end and a narrower end, the second end of said single spiral fluid ramp connected in fluid communication with the wider end of said frustoconical segment, the single spiral fluid ramp being tapered along a length of the single spiral ramp extending from the fluid inlet to the frustoconical segment, so that the cross-sectional area of the single spiral fluid ramp at the second end thereof is less than the cross-sectional area at the first end thereof, thereby achieving an increase in the speed of fluid flowing into the frustoconical segment; and a third segment comprising a tubular element having a first and second end, the first end of said tubular element being in fluid communication with and extending from the narrower end of said frustoconical segment, and said tubular element having an underflow outlet in the second end of said tubular element.
