Description
Technical Field
The invention belongs to the technical field of ultrasonic tomography, and relates to an ultrasonic plane wave scanning imaging system based on ultrasonic projection and reflection principles.
Background
The multiphase flow phenomenon is widely existed in modern industrial processes of bioengineering, oil and gas exploitation, chemical industry, metallurgical industry, food processing and the like, and the accurate detection of the flow process parameters has very important significance on monitoring, management, analysis and design of the production process, reliable operation of the device and production efficiency improvement. In scientific research and industrial application, the detection means of multiphase flow needs not to generate any disturbance to the measured fluid, and the ultrasonic method is concerned by the simple structure, no disturbance and low cost.
The ultrasonic detection is a technology which is widely applied, has unique advantages in medical monitoring and fluid measurement, cannot damage a flow field of fluid when ultrasonic waves are transmitted in the fluid, has no pressure loss, and has high harmless safety to human bodies. Meanwhile, if the detection element is arranged on the outer wall of the pipeline, the direct contact with the fluid can be avoided, and the corrosion degree of the sensor is reduced. Due to the fact that the propagation speeds of the ultrasonic waves in different acoustic impedance media are different, the phase medium distribution information on a propagation channel, such as the average acoustic impedance or the sound velocity of the media, can be obtained by utilizing the propagation characteristics of the ultrasonic waves in the multi-phase flow media. Particularly, the great difference of acoustic impedance at the gas phase interface and the liquid phase interface ensures that the reflection characteristic of the ultrasound at the gas-liquid interface is very obvious (up to 99 percent), so the ultrasound has excellent resolution capability on the gas-liquid interface. The ultrasonic phased array tomography method can obtain the distribution information of different acoustic impedance media in the measured cross section in a non-disturbance mode through a plurality of ultrasonic phased array probes arranged on the same cross section of the pipeline, for example, the transmission and reflection effects of ultrasonic waves in multiphase flow can be effectively utilized, and the visual reconstruction of the multiphase flow phase distribution and the estimation of distribution parameters can be accurately and comprehensively realized.
The traditional tomography technology based on the single-chip ultrasonic probe has certain limitations: the single probe emits sound waves in a fan shape (cone shape), the scanning range is narrow, the side lobe attenuation under the condition of a wide emission angle is large, the bubble projection in an ultrasonic path has an expansion trend, directional scanning cannot be realized, and the image reconstruction effect precision is not high under the conditions of a concave surface and multiple bubbles.
The ultrasonic phased array technology has the excellent characteristics of wide detection range, flexible detection angle, high detection efficiency, good detection effect, visual detection result and the like due to the excellent accessibility of the sound beam. The technical core is that a phased array probe formed by combining a plurality of piezoelectric wafers realizes the phased emission of ultrasonic waves by controlling the excitation time of each array element in the probe, thereby realizing the deflection and focusing of beams.
In recent years, ultrasonic phased array instrument systems for industrial detection are successively introduced domestically, but the products are mainly used for metal flaw detection or weld seam detection, the scanning mode is relatively fixed, and only a single ultrasonic phased array probe can be connected for detection.
