Background technology
Dual-Phrase Distribution of Gas olid technology (being called strength again carries) is to utilize the technology of air-flow as carrier conveying solid substance material in pipeline.At present, Pneumatic Conveying Technology has been widely used in the every field of industrial and agricultural production because advantages such as device safety, robotization height, clean environment firendly, easy to operate, flexible arrangement, becomes one of important means indispensable in the Modern Logistics Technology.
The general mode of movement of middle and high concentration (the solid and gas mass ratio is greater than 20) of claiming is carried for the concentrated phase strength.Compare with traditional dilute suspension mode of movement, the concentrated phase conveying is low owing to transporting velocity, solid-gas ratio big, the little particle that makes of gas solid separation amount is lighter to pipe wear, has the low and high characteristics of transfer efficiency of energy consumption.But also also immature at present aspect the research of theoretical and application, bigger to the dependence of experiment.So being carried out deep research, the middle and high concentration Gas-solid Two-phase Flow has important application.
For a long time, Dual-Phrase Distribution of Gas olid especially the flow-field test problem of high concentration diphasic flow be always the restriction its development bottleneck.Though this technology had obtained large development in recent years; High-end measuring technologies such as capacitance chromatography imaging method, Doppler technology, X ray technology, laser measurement, PIV technology, rest potential measurement have successively appearred; But these technology are mostly only for being used among the less dilute phase of solid concentration flows, and these measuring technologies flowing environment is required too high, relatively poor to the pipeline applicability of relative complex; Instrument costs an arm and a leg, and expense is too high.Therefore, the method for testing of exploring cheap novel test means or using for reference other applications is to solve the effective way that Gas-solid Two-phase Flow is measured difficulty at present.
The ultrasonic tesint technology is one of flow field measurement technique commonly used.When ultrasound wave is propagated, can carry information about fluids in fluid.Therefore, the ultrasonic signal that receives is carried out analytical calculation, can detect relevant flow field information.The ultrasonic tesint technical development is very fast, it have measurement range wide, measure accurately, receive medium parameter to influence advantage such as little, easy for installation and widespread use.To Gas-solid Two-phase Flow field ultrasonic tesint Study on Technology and exploitation, have important use and be worth.
