IMPROVED HELICAL SEPARATOR

摘要

The invention relates to an improved liquid/gas helical separator whose operating principle is based on a combination of centrifugal and gravitational forces. Generally speaking, the separator consists of a primary separator (I), formed basically by an expansion chambe r, a secondary separator (III), formed basically by a helix (14a) for directing the flow; a tertiary separator (III), which consists of a reservoir or gravitational-separation tank and of a transition region (II) between the primary (I) and secondary (III) separators, which consists of at least t wo variable-pitch helixes (14a, 14b), whose inclination varies from an angle of 90.degree. to the angl e of inclination of the constant-pitch helix of the secondary separator (III), with the function of providing a "gentler" flow of the liquid phase at the transition between the first two separators (I, III).
