Device for the transformation of gas/liquid flow to laminar or stratified flow

Abstract

A device in connection with a pipe ( 1 ) for transformation of dispersed gas/liquid flow into laminar stratified flow. The solution involves a first set of stationary guide blades ( 6 ) being arranged in the pipe ( 1 ) and being designed to rotate the liquid/gas flow. The pipe ( 1 ) is, in turn, connected to a second pipe ( 2 ) with the same or a different diameter and, in the transition between the pipe ( 1 ) and the second pipe ( 2 ), there is a second set of blades or a device ( 8 ) that is designed to stop the rotation of the gas. The natural flow pattern of the gas/liquid in the second pipe ( 2 ) then becomes stratified over a predefined distance.

1 - 5 . (Cancelled)  
   
   
       6 . A device in connection with a pipe for transformation of dispersed liquid/gas flow into stratified flow, wherein a first set of stationary guide blades is arranged in the pipe and is designed to rotate the liquid/gas flow, the pipe is connected to a second pipe with the same or a different diameter and, in a transition between the pipe and the second pipe, there is a second set of blades or a device that is designed to stop the rotation of the gas so that the natural flow pattern of the gas/liquid in the second pipe becomes stratified over a predefined distance.  
   
   
       7 . A device in accordance with  claim 6 , wherein the second pipe has a larger diameter than the first pipe.  
   
   
       8 . A device in accordance with  claim 6 , wherein a venturi is arranged in the pipe, and the first set of guide blades is arranged at the inlet of the venturi, while the second set of guide blades is arranged at the outlet of the venturi.  
   
   
       9 . A device in accordance with  claim 6 , wherein the second device is a perforated plate.  
   
   
       10 . A device in accordance with  claim 9 , wherein the perforated plate is arranged at an angle in relation to the longitudinal direction of the pipe.  
   
   
       11 . A device in accordance with  claim 7 , wherein the second device is a perforated plate.  
   
   
       12 . A device in accordance with  claim 8 , wherein the second device is a perforated plate.
