Description
Technical field
The present invention relates to the apparatus and method of a kind of X ray and ultrasonic combined measurement Multiphase Flow parameter, belong to technical field of multiphase flow measurement.
Background technology
Various material can describe with three kinds mutually in the existence form of occurring in nature, i.e. gas phase, liquid phase and solid phase.Multiphase Flow is often referred to the flowing of two or more material, and these materials can exist with any one form in above-mentioned three-phase.Multiphase Flow is one of modal phenomenon of occurring in nature, and the band sand drift of such as natural water moves, mud-stone flow disaster etc.Simultaneously, in the production that Multiphase Flow phenomenon is also present in numerous industrial or agricultural field widely and processing procedure, such as petrochemical complex catalytic cracking production run, metallurgical Mineral Floating Process, seed pelleting process etc. in wastewater treatment in aeration tank purification process and agricultural production, the device completing above process all belongs to heterophase reactor.
Understanding and grasp heterophase reactor (as catalytic cracking tower, ore floatation machine, sewage aeration pond etc.) interior flowing law are basis and the key point of its optimal design and Effec-tive Function.But owing to including gas and liquid two kinds of continuous phases and solid discrete phase in heterophase reactor, compared with single-phase flowing or diphasic flow, its flowing law is more complicated, and its nowed forming and flow parameter are (as the Content and distribution of each phase, each phase movement velocity etc.) be more difficult to measure, research for gas-liquid-solid three-phase flowing in heterophase reactor is usually difficult to carry out, and causes depending on engineering experience more than the design and operation of multiple industrial multiphase reactor.Therefore the non-intrusion type method for three-dimensional measurement for gas-liquid-solid three-phase flowing in heterophase reactor and measurement mechanism is developed, and on this basis, its inside gas-liquid-solid three-phase flowing rule is conducted a research, the mechanism of understanding Heat and mass transfer between phases, under final grasp different operating parameter, the moving law of heterophase reactor, all has great importance to scientific research, engineering design and commercial Application.
At present, the measurement means for flow parameter in heterophase reactor is main still to use for reference the measuring method of single-phase flowing or diphasic flow.Such as pitot tube, PIV method, radioelement labelling method, sampling and measuring method, based on X-ray or hyperacoustic method.Pitot tube belongs to intrusive mood measurement means, easily causes interference to flowing, is originally mainly used in the fluid-velocity survey of single continuous phase, the speed of approximate measure continuous phase is may be used in gas-liquid-solid three-phase flowing, accuracy is poor, and because flowing is containing solid phase, easily causes pitot tube aperture to block.PIV is mainly used in the measurement of continuous phase turbulence structure and the motion of Gas-solid Two-phase Flow solid phase originally, the nowed forming of gas-liquid-solid three-phase flowing and the measurement of flow parameter under certain conditions can be used, but measure owing to belonging to visible ray, often helpless for blocking of alternate or flow interface.Radioelement labelling method is a kind of contactless measurement, may be used for the velocity survey of continuous phase or discrete phase or the measurement of phase content, but the use of radioelement is often along with safety problem.Sampling and measuring method mainly measures each phase content by the sample obtaining the flowing of a part of gas-liquid-solid three-phase, but sampling and measuring method is a kind of intrusive mood measuring method, and can produce interference to three phase flow, therefore accuracy also has certain problem.Measuring technique that is the most potential and that wish is based on X-ray or hyperacoustic method.Both all belong to contactless measuring method, but, because X-ray penetration capacity is comparatively strong, make X-ray transmission method often be difficult to provide the measurement data of gas phase, and its three-dimensional data that three-phase can not be provided to distribute; Although X-ray tomography method can provide the three-dimensional data (disclosed in CN200510086250.2 method) of detailed three-phase distribution, because its tomographic scanning procedure duration is long, cause its time poor accuracy; Ultrasonic method accuracy and information integrity better, but easily cause violent decay when it runs into solid phase, cause error, so it is usually for the measurement (disclosed in CN201210321362.1, CN200610015327.1 method) of gas liquid two-phase flow.
In heterophase reactor, the measurement of flow parameter is all an international difficult problem all the time, and stream field is noiseless, three peacekeepings are accurate not have a kind of method to realize completely at present.In order to promote the scientific research of heterophase reactor, engineering design and commercial Application energetically, lot of domestic and foreign colleges and universities, scientific research institution and enterprise all drop into a large amount of manpower and materials, be devoted to gas-liquid-solid three-phase flowing parameter measuring apparatus and the method for development of new, to grab the highland of intellecture property.
