Title
(EN) Multiphase flow mass metering device based on ray coincidence measurement
(ZH) 基于射线符合测量的多相流量质量计量装置
Abstract
(EN)
The utility model relates to a multiphase flow mass metering device based on ray coincidence measurement. The ray detection device comprises a supporting frame, a pipeline through hole allowing a fluid pipeline to pass through is formed in the center of the supporting frame, a plurality of ray detection assemblies are arranged on the outer wall of the pipeline through hole, and the ray detection assemblies are distributed in the circumferential direction perpendicular to the pipeline through hole. The ray detection assembly comprises a scintillation crystal and a detector, and the scintillation crystal is located between the outer wall of the pipeline through hole and the detector. According to the utility model, the intrinsic rays of the scintillation crystal are used for total cross-section measurement, so that a radioactive source in a ray measuring device in the prior art can be canceled, the cost of the system is reduced, the volume of equipment is reduced, and the safety and reliability of the system are greatly improved. Meanwhile, the half-life period of Lu-176 is 2.1 * 10 < 10 > years, so that the performance of the equipment is not reduced due to aging of the radiation device, the stability of the system is greatly improved, and the service life of the system is greatly prolonged.
