Abstract
A porous bed centrifuge for continuous separation of immiscible liquids, for example water and mineral oil/petroleum, obtained by a modification to conventional disk centrifuges for increasing their efficiency, wherein the disks have been substituted by a filling of solid particles that act as a filtrating and coalescent bed.
Claims16
A continuous porous bed centrifuge for the continuous separation of a fluid consisting of two immiscible liquids in dispersion, which comprises:
- a) a first outer compact essentially conical-shaped rotating skirt;
- b) a second inner compact essentially conical-shaped skirt, integral with the outer skirt and positioned so as to form an interspace with said outer skirt;
- c) a perforated toroidal-shaped separation element positioned at the base of the two skirts and suitable for separating the interspace from the inside of the centrifuge;
- d) a closing base integral with the outer skirt by means of a sealing gasket;
- e) a section, equipped with a weir acting as a flow regulator, fixed at the head of the outer skirt and with openings for the discharge of the separated liquids;
- f) a first coaxial tube, integral with the outer skirt and with section (e);
- g) a second coaxial tube which is not integral with the outer skirt, positioned inside the first tube, for the feeding of the dispersion;
- h) a filling in the form of particles capable of filling from 40 to 70% of the inner volume of the centrifuge.
