要約
(EN)
The present invention addresses the problem of measuring appropriate dryness even when a pipe is inclined. A dryness measurement device is characterized by being provided with: a light incidence unit (11) which causes light to be incident along a light path (L) preset in a pipe (20) through which wet steam to be measured flows; a light reception unit (12) which detects the intensity of light transmitted through or reflected by the wet steam; and a dryness specification unit (100) which specifies the dryness of the detected wet steam on the basis of the detected light intensity, and characterized in that the light path (L) is set so as to pass a liquid-phase portion (w) flowing along the inner wall of the pipe (20) of the wet steam, the dryness specification unit (100) calculates the dryness of the wet steam on the basis of the detected light intensity (I), the areas (Sa/Sw) of a gas-phase portion and the liquid-phase portion of the wet steam which correspond to the light intensity (I), a speed difference (Δv) between the gas-phase portion and the liquid-phase portion of the wet steam, and a density difference (Δρ) between the gas-phase portion and the liquid-phase portion of the wet steam.

La présente invention concerne un dispositif de mesure de siccité même lorsqu'un tuyau est incliné. Un dispositif de mesure de siccité est caractérisé en ce qu'il est doté : d'une unité d'incidence lumineuse (11) qui provoque l'incidence de la lumière le long d'un chemin de lumière (L) prédéterminé dans un tuyau (20) à travers lequel de la vapeur humide à mesurer s'écoule ; une unité de réception de la lumière (12) qui détecte l'intensité de la lumière transmise à travers la vapeur humide ou reflétée par celle-ci ; et une unité de spécification de siccité (100) qui spécifie la siccité de la vapeur humide détectée sur la base de l'intensité lumineuse détectée, et caractérisé en ce que le chemin de lumière (L) est fixé de façon à faire passer une partie en phase liquide (w) circulant le long de la paroi interne du tuyau (20) de la vapeur humide, l'unité de spécification de siccité (100) calcule la siccité de la vapeur humide sur la base de l'intensité lumineuse détectée (I), les zones (Sa/Sw) d'une partie en phase gazeuse et la partie en phase liquide de la vapeur humide qui correspondent à l'intensité lumineuse (I), une différence de vitesse (Δv) entre la partie en phase gazeuse et la partie en phase liquide de la vapeur humide, et une différence de densité (Δρ) entre la partie en phase gazeuse et la partie en phase liquide de la vapeur humide.

配管が傾いている場合であっても適正な乾き度を測定することを課題とする。測定対象の湿り蒸気が流れる配管(20)に予め設定した光経路(L)に沿って光を入射させる光入射部(11)と、湿り蒸気を透過または反射した光の強度を検出する受光部(12)と、検出された光の強度に基づいて検出した湿り蒸気の乾き度を特定する乾き度特定部(100)とを備え、光経路(L)は、配管(20)の内壁に沿って流れる湿り蒸気の液相部分(w)を通るように設定されており、乾き度特定部(100)は、検出された光の強度(I)、当該光の強度(I)に対応する湿り蒸気の気相部分および液相部分の面積(Sa/Sw)、湿り蒸気の気相部分と液相部分との速度差(Δv)、並びに湿り蒸気の気相部分と液相部分との密度差(Δρ)に基づいて湿り蒸気の乾き度を演算することを特徴とする。
