Abstract:
A hydrocyclone for effecting separation of a combined phase input stream, comprising an inner shell residing concentrically within an outer shell, the two shells forming an annular space therebetween of constant width, a tangentially oriented inlet means leading into the annular space, and an outlet means communicating with the annular space, wherein the inlet means is circular in cross-section, and wherein a transition means is provided connectingly between the inlet means and an entry point into the annular space wherein the cross-section of a path of flow of the input stream is changed from circular to essentially rectangular, wherein the length of the rectangular cross-section parallel to the axis of the two shells is greater than its width, wherein the inner shell and the outer shell are each formed as truncated cones tapering in the direction away from the inlet, the truncated cone of the inner shell being terminated at the same level as the truncated cone of the outer shell.
