Abstract
(EN)
Disclosed is a multiphase flow mass metering device based on ray coincidence measurement. A ray detection device comprises a support frame (1), wherein a pipeline through hole (2) for a fluid pipeline to pass through is provided at the center of the support frame (1); several ray detection assemblies (3) are provided on an outer wall of the pipeline through hole (2), and the ray detection assemblies (3) are distributed in a circumferential direction perpendicular to the pipeline through hole (2); and each of the ray detection assemblies (3) comprises a scintillation crystal (31) and a detector (32), and the scintillation crystal (31) is located between the outer wall of the pipeline through hole (2) and the detector (32). The multiphase flow mass metering device carries out total cross-section measurement by using an intrinsic ray of the scintillation crystal (31), such that a radioactive source in a ray measurement device in the prior art can be canceled, the cost of a system is lowered, the volume of an apparatus is reduced, and the safety and reliability of the system are greatly improved. Moreover, since the half-life period of Lu-176 is 2.1 x 1010 years, the performance of the apparatus is not reduced due to aging of a radiation device, such that the stability of the system is greatly improved and the service life of the system is greatly prolonged.

L'invention concerne un dispositif de mesure d'écoulement massique polyphasique basé sur une mesure par coïncidence de rayons. Un dispositif de détection de rayons comprend un cadre de support (1), un trou débouchant de pipeline (2) pour un pipeline de fluide devant le traverser étant disposé au centre du cadre de support (1) ; plusieurs ensembles de détection de rayons (3) sont disposés sur une paroi externe du trou débouchant de pipeline (2), et les ensembles de détection de rayons (3) sont répartis dans une direction circonférentielle perpendiculaire au trou débouchant de pipeline (2) ; et chacun des ensembles de détection de rayons (3) comprend un cristal à scintillation (31) et un détecteur (32), et le cristal à scintillation (31) est situé entre la paroi externe du trou débouchant de pipeline (2) et le détecteur (32). Le dispositif de mesure d'écoulement massique polyphasique effectue une mesure de section transversale totale à l'aide d'un rayon intrinsèque du cristal à scintillation (31), de telle sorte qu'une source radioactive dans un dispositif de mesure de rayons dans l'état de la technique peut être annulée, le coût d'un système est abaissé, le volume d'un appareil est réduit et la sécurité et la fiabilité du système sont considérablement améliorées. De plus, étant donné que la période de demi-vie de Lu-176 est de 2,1 x 1010ans, la performance de l'appareil n'est pas réduite en raison du vieillissement d'un dispositif de rayonnement, de telle sorte que la stabilité du système est considérablement améliorée et la durée de vie du système est considérablement prolongée.
