Description
Technical field
The utility model relates to a kind of Parameter Measurement of Gas-liquid Two-phase device, specifically a kind of device of non-intervention monitoring biphase gas and liquid flow pipeline flow pattern.
Background technology
Biphase gas and liquid flow extensively is present in nature and the many industrial processs, when gas-liquid mixture flows in pipeline, along with the difference of liquid phase flow, medium physical property, pressure, thermal load, geometric pipeline shape, gas-liquid two-phase can present different distribution forms, i.e. flow pattern by in-line.Common flow pattern has stratified flow, annular flow, slug flow etc.Flow pattern is to describe a key character parameter of two-phase flow, greatly affects the diphasic flow pressure loss and heat transfer characteristic.On-line monitoring two-phase flow pattern is significant for the safety and efficiently operation of the pipeline that ensures biphase gas and liquid flow.
Common flow type identification method has two kinds of direct method and indirect methods.Indirect method is mainly carried out analyzing and processing by the fluctuation signal to reflection two phase flow characteristic, extracts flow pattern features, and then the identification flow pattern.Patent of invention CN2476015 discloses the instrument of multiphase flow pattern in a kind of ONLINE RECOGNITION level or the tipping tube, be comprised of microprocessor, bus, data collecting card, liquid crystal display etc., the pressure signal of measurement and differential pressure signal are analyzed with flow pattern collection signal by microprocessor and are identified.Gaging pressure or differential pressure signal need to carry out perforate in order to pressure-inducting device is installed to existing pipeline, have increased medium leakage risk.Simultaneously, in actual measurement, the distribution that the gas-liquid two-phase in the pipeline flows spatially is random fluctuation, and indirect method identification flow pattern has very large limitation.
Direct method is directly determined flow pattern according to the form of two phase flow image.Directly flow type identification method mainly contains observation, sonde method, chromatography imaging method etc.Observation adopts the instruments such as visual inspection or employing high-speed camera directly to observe two-phase flow pattern in the transparent pipeline by transparent visualization window, has simply and intuitively advantage, but this method is with observer's subjective factor, and the differentiation of convection often varies with each individual.

Embodiment
By shown in Figure 1, the utility model is by ultrasonic echo measurement module 1, signal acquisition module 2, echo identification module 3, flow pattern output module 4 forms, and ultrasonic echo measurement module 1 is comprised of three ultrasonic probes, and ultrasonic probe links to each other with signal acquisition module 2 by data line 5 respectively, signal acquisition module 2 links to each other with echo identification module 3 by data line 6, and echo identification module 3 links to each other with flow pattern output module 4 by data line 7.
The utility model measuring principle is described in detail as follows:
Reflection and transmission can occur at its contact interface during by two kinds of different materials in ultrasound wave, and its pressure reflection ratio and transmissivity are used respectively the calculating of (1) and (2) formula.
Reflectivity:
Transmissivity:
The R-reflectivity; The D-transmissivity; Z
1-medium 1 acoustic impedance; Z
2-medium 2 acoustic impedances.
If wall surface material is steel, the gas, liquid medium is respectively the sky G﹠W, then can detect: the acoustic impedance of air is Z
A=0.00004 * 10
6/ (g.cm
-2.s), the acoustic impedance Z of water
w=0.148 * 10
6/ (g.cm
-2.s), the acoustic impedance Z of steel
s=4.5310
6/ (g.cm
-2.s).
During the generation echo first time, when steel pipe inner wall is liquid medium (water), sound pressure reflection coefficient:
When steel pipe inner wall is gas medium (air), sound pressure reflection coefficient:
Relatively the reflectivity in the following formula finds that its difference is about 0.064, its dB value differ into
As seen for the first time echo gas, liquid echo difference are very little, if but ultrasound wave back and forth transmission 10 times in the steel wall, its difference is 5.7dB, as seen along with the increase of echo times, the difference of gas, liquid echoing characteristics is day by day obvious.When gas, liquid contacted with tube wall respectively, the echoed signal attenuation characteristic that ultrasonic inspection probe is surveyed was fully different in other words.
Be arranged in the ultrasonic probe 8 on the gas-liquid two-phase pipeline 11 pipe outer walls, ultrasonic probe 9, ultrasonic probe 10 is to the interior Vertical Launch ultrasound wave of pipe, because the acoustic impedance difference between gas phase and the solid wall surface will be much larger than corresponding liquid phase, according to formula (1) and (2) as can be known, when inside pipe wall contacted with gas phase, the energy that transmission occurs was relatively less, most of energy is reflected back, and is again accepted by ultrasonic probe.Echo attenutation speed when therefore its echo attenutation speed will contact with liquid phase much smaller than tube wall when tube wall contacts with gas phase.Fig. 2 is the attenuation characteristic comparison diagram when contacting with tube wall respectively according to liquid phase, the echo attenutation figure of Fig. 2-a when to be that inside pipe wall is gentle contact, and Fig. 2-b is inside pipe wall echo attenutation figure when contacting with liquid phase.On scheming, can find out that the two echoing characteristics has significant difference.When inside pipe wall contacted with liquid phase, because some transmission has occured, energy attenuation was very fast, and inside pipe wall is gentle when contacting, the transmissivity less, and echo attenutation is slow.Can judge that according to the difference of inside pipe wall echoing characteristics what contact with inner-walls of duct with probe position place is gas phase or liquid phase.
By shown in Figure 3, when the stratified flow, under Action of Gravity Field, gas phase is mobile at the pipeline top in pipe, and liquid phase is at the pipeline flows, obvious liquid-gas interface 13 of biphase gas and liquid flow pipeline 11 interior existence.Numerous scholar's research achievements show that for the layering flow pattern, its liquid-gas interface 13 distance pipe end maximum heights are less than 1/2 of caliber.Ultrasonic probe 10 is positioned at 6 o'clock of tube wall place, and what contact with inside pipe wall is always liquid phase herein, so the echoed signal decay comparatively fast.Flow pattern identification module 3 with the echo attenutation data at ultrasonic probe 10 places as a reference, compare with other two places ultrasonic probe measurement data, when ultrasonic probe 8, ultrasonic probe 9 is positioned at liquid-gas interface 13 when above, because inner-walls of duct is that gas phase contacts with tube wall herein, the ultrasound echo signal of measurement will more than the decay of ultrasonic probe 10 places slowly.In view of the slug flow cycle is generally less than 60s, so acquisition time is defined as 60s～120s.If in 60s～120s Measuring Time section, ultrasonic probe 8 is consistent with the echoed signal that ultrasonic probe 9 receives, and the echo attenutation degree is much smaller than 10 place survey time of ultrasonic probe ripple signal, show that then the conduit upper space is always gas phase, the pipeline bottom is always liquid phase, and flow pattern output module output flow pattern is stratified flow.
By shown in Figure 4, when the gas-liquid two-phase flow pattern was the ring-type flow pattern in the pipe, liquid phase was being pasted tube wall with the liquid film form and is being flowed, and the centre is swiftly flowing gas phase.Because whole tube wall is all covered by liquid film, the inner-walls of duct echoed signal that ultrasonic probe 8, ultrasonic probe 9, ultrasonic probe 10 are measured all presents consistent attenuation characteristic.If at 60s～120s in the time interval, the ultrasonic echo feature of three ultrasonic probe measurements is consistent, and marked change does not all occur in the measuring process, then shows on biphase gas and liquid flow pipeline 11 inwalls to be always liquid phase, the pipeline bottom is always liquid phase, and flow pattern output module 4 output flow patterns are annular flow.
By shown in Figure 5, when being liquid holdup in the pipeline, bubble 14 and liquid plug 15 alternating currents are crossed tube section.Interim when bubble 14, its fluidal texture and stratified flow are similar, and three ultrasonic probe institute survey time ripple signals are also consistent with stratified flow.And work as liquid plug 15 temporarily, whole tube section is occupied by liquid phase, ultrasonic probe 8, ultrasonic probe 9 measured echoed signal characteristics will be undergone mutation at this moment, it is basic identical that the echo waveform feature of measuring this moment is measured echoed signal with ultrasonic probe 10, shows that these moment biphase gas and liquid flow pipeline 11 inwalls are covered by liquid phase.If in the time interval, possess as above Characteristics of Mutation if three ultrasonic probes are measured echoed signal at 60s～120s, flow pattern output module 4 judges that flow pattern is intermittent flow.
Therefore, according to the ultrasonic echo feature that three ultrasonic probes are measured, can determine respectively place, three probe places inner-walls of duct is gas phase or liquid phase.Because flow pattern is different, the distribution form of gas, liquid on tube section is different, and be also not identical at all distribution forms of pipe, can identify stratified flow common in the biphase gas and liquid flow pipeline, annular flow, three kinds of common flow patterns of slug flow.
The utility model carries out analyzing and processing by the echo data that the ultrasonic probe on the deployment tube outer wall unique point is measured, can accurately identify the common flow pattern of biphase gas and liquid flow pipeline, need not complicated reconstruction calculations, can measure in real time online, be complete non-intervention type measurement mechanism, do not need existing pipeline is changed, to measuring channel caliber, pipe wall material, measurement liquid phase medium character and temperature, the equal no requirement (NR) of pressure, the scope of application is broad.
