Title (EN) GAS-LIQUID SEPARATION DEVICE
(FR) DISPOSITIF DE SÉPARATION GAZ-LIQUIDE
(JA) 気液分離装置
Abstract:
(EN) Provided is a gas-liquid separation device that can prevent a liquid that has been atomized from flowing with a gas when gas-liquid separation has been performed by swirling a gas-liquid two-phase fluid while suppressing increases in the size of the device. A gas-liquid separation device is configured so as to be provided with an inlet pipe (21) wherein a gas-liquid two-phase fluid flows, and a swirling flow generating ribbon (30) disposed inside the inlet pipe (21) and swirling the gas-liquid two-phase fluid along the inside circumferential surface (21b) thereof, and such that a first stepped surface (41) wherein the inside diameter dimension of the inlet pipe (21) increases toward the downstream side is formed on the inside circumferential surface (21b) of the inlet pipe (21) on the downstream side of the swirling flow generating ribbon (30) in the direction of flow of the gas-liquid two-phase fluid.
(FR) L'invention concerne un dispositif de séparation gaz-liquide qui peut empêcher un liquide qui a été atomisé de s'écouler avec un gaz lorsqu'une séparation gaz-liquide a été effectuée par tourbillonnement d'un fluide biphasé gaz-liquide tout en supprimant des augmentations de la taille du dispositif. Un dispositif de séparation gaz-liquide est configuré de façon à être pourvu d'un tuyau d'entrée (21) dans lequel s'écoule un fluide biphasé gaz-liquide, et un ruban de génération d'écoulement tourbillonnant (30) disposé à l'intérieur du tuyau d'entrée (21) et tourbillonnant le fluide biphasé gaz-liquide le long de la surface circonférentielle intérieure (21b) de celui-ci, et de telle sorte qu'une première surface étagée (41) dans laquelle la dimension de diamètre intérieur du tuyau d'entrée (21) augmente vers le côté aval est formée sur la surface circonférentielle intérieure (21b) du tuyau d'entrée (21) sur le côté aval du ruban de génération d'écoulement tourbillonnant (30) dans la direction d'écoulement du fluide biphasé gaz-liquide.
(JA) 装置の大型化を抑制しつつ、気液二相流体を旋回させて気液分離したときに液滴化した液体が気体と共に流れることを防止できる気液分離装置を提供すること。 気液二相流体が流れるインレットパイプ(21)と、インレットパイプ(21)の内部に配置されて気液二相流体を内周面(21b)に沿って旋回させる旋回流発生リボン(30)と、を備え、旋回流発生リボン(30)よりも気液二相流体の流れ方向の下流側のインレットパイプ(21)の内周面(21b)に、下流側に向かってインレットパイプ(21)の内径寸法が大きくなった第1段差面(41)が形成されている構成とした。
