| 摘要 |
A hydrocyclone (2) for separating a combined phase input stream has two nesting truncated downwardly tapering conical members (10, 12) having an annular spa ce (14) therebetween. A tangential inlet (8) leads to the annular space (14) between the cones (10, 12). Alternate embodiments applicable to a hydrocyclone device composed of nesting cylindrical or conical shells forming an annular cyclonic space have passage s (39, 41) located on either of the shells (10, 12) to effect an intermediate draw off of a fraction of the flow stream. In addition, a coiled, hollow tube (16) is advantageously situated within the annular space (14) to optimize the flow pattern. Ports (50) may be provided in the hollow tube (16) for removing a gas fraction in counterflow orientation.</SD OAB>
