Problems solved by technology

[0007] The purpose of the present invention is to provide an array type ultrasonic scanning imaging system for multiphase flow measurement. Aiming at the problems of fewer channels and lower imaging accuracy of the ultrasonic tomography system currently used for multiphase flow measurement, the ultrasonic Phased array probes increase the number of detection channels, use a modular design to simplify the complexity of a large number of channel systems, and facilitate system expansion and maintenance

Abstract

The invention relates to an array type ultrasonic scanning imaging system for multiphase flow measurement. A modular design scheme is adopted, the system comprises an ultrasonic phased array sensor, amain control module, M transceiving front-end modules and a back plate. The system is characterized in that the ultrasonic phased array sensor is formed by uniformly distributing M ultrasonic phasedarray probes at the same cross section position of a measured pipe section, each ultrasonic phased array probe is formed by linearly arranging N array elements, and each array element can be independently excited and received. Plane waves with different angles are generated according to a set scanning mode for scanning; and after each ultrasonic phased array probe transmits a group of plane waveswith different angles and scanning is finished, the next adjacent ultrasonic phased array probe is switched on for excitation until all the ultrasonic phased array probes scan for one circle in sequence, and excitation and acquisition of one piece of section data are completed.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic tomography, and relates to an ultrasonic plane wave scanning imaging system based on the principle of ultrasonic projection and reflection. Background technique [0002] Multiphase flow phenomena widely exist in modern industrial processes such as bioengineering, oil and gas extraction, chemical industry, metallurgical industry, and food processing. Accurate detection of flow process parameters can monitor, manage, analyze and design production processes, and ensure that devices It is of great significance to operate reliably and improve production efficiency. In scientific research and industrial applications, the multiphase flow detection method needs to not cause any disturbance to the measured fluid, and the ultrasonic method has attracted much attention due to its simple structure, non-disturbance, and low cost. [0003] Ultrasonic testing is a widely used technology. It has its unique ad...
