Abstract
Abstract A centrifugal vapor-liquid separator is formed by a vertically extending riser pipe closed at its upper end and laterally enclosed by a collecting shell so that a collecting space laterally surrounds the riser pipe. An impeller provided with two sets of separate passageways and located at the upper end of the riser pipe flows the vapor-liquid mixture from the riser pipe through one set of passageways into the collecting space and gives it a swirling motion. The liquid and vapor separate in the collecting space with the separated liquid exiting from the space either upwardly or downwardly along the inside wall of the shell. Vapor carried over into the collecting space below the impeller flows out through the other set of passageways extending upwardly through the impeller into a vapor discharge pipe located above the upper end of the riser pipe.

Claim 1
Independent Claim
504 words
A centrifugal vapor-liquid separator comprising an upwardly extending riser pipe for conducting a vapor-liquid mixture in the upward direction, means forming a closure for the upper end of said riser pipe, a collecting shell laterally enclosing and spaced outwardly from said riser pipe and extending upwardly above and downwardly below the upper end of the said riser pipe and forming an annular space about said riser pipe, an impeller located at the upper end of said riser pipe below said closure means and forming outlet passageways for the vapor-liquid mixture passing upwardly through said riser pipe into the annular space between said collecting shell and said riser pipe, said impeller having a plurality of blades oriented radially outwardly from said riser pipe for directing the vapor-liquid mixture from the upper end of said riser pipe outwardly into the space between said riser pipe and said collecting shell, a vapor discharge pipe located above said riser pipe and arranged in communication with the upper side of said impeller, said impeller forming upwardly directed passageways communicating between the space below said impeller which is located between the outer surface of said riser pipe and the inner surface of said collecting shell and said vapor discharge pipe, wherein the improvement comprises that said plurality of blades comprises first blades and second blades, said first blades arranged in laterally spaced side-by-side relationship at least in pairs, with each pair of said blades forming a first passageway therebetween and said second blades interspersed between said first blades, so that at least one said second blade is located between adjacent pairs of said first blades and the at least one said second blade and the juxtaposed surfaces of said first blades in the adjacent pairs of said first blades form therebetween second passageways, said impeller includes first wall means and second wall means, with said first wall means oriented upwardly and extending between the radially inner edges and between the radially outer edges of each pair of said first blades forming the first passageways so that the first passageways are closed on the radially inner and outer sides of said impeller and are open on the upper and lower surfaces of said impeller, and said second wall means are oriented transversely of the upward direction and extend between the upper edges between the lower edges of said first and second blades forming the second passageways so that the second passegways are closed on the upper and lower sides of said impeller and are opened at the radially inner and outer sides and form the outlet passageways for conducting vapor-liquid mixture from said riser pipe into the space within said collecting shell outwardly from said impeller and said first passageways forming the upwardly directed passageways connecting the space below said impeller between said riser pipe and said collecting shell with said vapor discharge pipe so that vapor can flow upwardly through said impeller into said vapor discharge pipe without interfering with the flow of vapor-liquid mixture passing through the second passageways.
Claim 2
Dependent Claim

A centrifugal vapor-liquid separator comprising an upwardly extending riser pipe for conducting a vapor-liquid mixture in the upward direction, means forming a closure for the upper end of said riser pipe, a collecting shell laterally enclosing and spaced outwardly from said riser pipe and extending upwardly above and downwardly below the upper end of the said riser pipe and forming an annular space about said riser pipe, an impeller located at the upper end of said riser pipe below said closure means and forming outlet passageways for the vapor-liquid mixture passing upwardly through said riser pipe into the annular space between said collecting shell and said riser pipe, said impeller having a plurality of blades oriented radially outwardly from said riser pipe for directing the vapor-liquid mixture from the upper end of said riser pipe outwardly into the space between said riser pipe and said collecting shell, a vapor discharge pipe located above said riser pipe and arranged in communication with the upper side of said impeller, said impeller forming upwardly directed passageways communicating between the space below said impeller which is located between the outer surface of said riser pipe and the inner surface of said collecting shell and said vapor discharge pipe, wherein the improvement comprises that said plurality of blades comprises first blades and second blades, said first blades arranged in laterally spaced side-by-side relationship at least in pairs, with each pair of said blades forming a first passageway therebetween and said second blades interspersed between said first blades, so that at least one said second blade is located between adjacent pairs of said first blades and the at least one said second blade and the juxtaposed surfaces of said first blades in the adjacent pairs of said first blades form therebetween second passageways, said impeller includes first wall means and second wall means, with said first wall means oriented upwardly and extending between the radially inner edges and between the radially outer edges of each pair of said first blades forming the first passageways so that the first passageways are closed on the radially inner and outer sides of said impeller and are open on the upper and lower surfaces of said impeller, and said second wall means are oriented transversely of the upward direction and extend between the upper edges between the lower edges of said first and second blades forming the second passageways so that the second passegways are closed on the upper and lower sides of said impeller and are opened at the radially inner and outer sides and form the outlet passageways for conducting vapor-liquid mixture from said riser pipe into the space within said collecting shell outwardly from said impeller and said first passageways forming the upwardly directed passageways connecting the space below said impeller between said riser pipe and said collecting shell with said vapor discharge pipe so that vapor can flow upwardly through said impeller into said vapor discharge pipe without interfering with the flow of vapor-liquid mixture passing through the second passageways.
Claim 3
Dependent Claim
100 words
A centrifugal vapor-liquid separator, as set forth in claim 1, wherein a drainage pipe is connected at its upper end to said means forming the closure for the upper end of said riser pipe and is arranged in communication with said discharge pipe, said drainage pipe extending downwardly from the closure from the upper end of said riser pipe through said riser pipe spaced inwardly from said impeller and at a location below said impeller, said drainage pipe passes outwardly through said riser pipe and communicates with the space between said collection shell and said riser pipe below said impeller.
