Abstract
Hydrocyclone feasible for autonomous and continuous removal of sand or other heavier particulate material from a continuous medium of liquid and sludge, merely by static control parts, wherein the hydrocyclone comprises an inlet, a hydrocyclone body with a cylindrical part and a conical part or a transitional cylinder-cone body, a reject outlet in the narrow end of the conical body and an accept outlet at the end of the cylindrical part of the hydrocyclone body, distinguished in that: the diameter of the inlet, one or several in sum, is ⅖ of the diameter of the hydrocyclone, within ±30%, or if the inlet is volute, rectangular or has other cross section shape than circular, a cross-section area of the inlet or inlets in sum corresponding to a circular inlet with diameter ⅖ of the diameter of the hydrocyclone, within ±30%; wherein the diameter of the hydrocyclone is the diameter of the cylindrical part or the diameter of the widest end of the conical part of the hydrocyclone body, the diameter of the accept outlet/vortex finder (liquid and sludge) is ⅗ of the hydrocyclone diameter, within ±30%; the diameter of the reject outlet (sand or sandy sludge) is ⅕ of the hydrocyclone diameter, within ±30%; the length of the cylindrical part of the hydrocyclone body is between 1 and 2 times the hydrocyclone diameter; the length of the conical part of the hydrocyclone is between 1 and 3 times the hydrocyclone diameter; and the hydrocyclone, when in operation, is oriented with the reject outlet directed at an angle in the range 0-90° upward from horizontal.
