Embodiment
For the purpose, technical scheme and advantage of the embodiment of the present invention are more clearly understood, below in conjunction with the accompanying drawings to this hair Bright embodiment is described in further details.Here, the schematic description and description of the present invention is used to explain the present invention, but simultaneously It is not as a limitation of the invention.
In order to realize the lossless audio coding of oil content in oily sludge water-washing process, the embodiment of the present invention provides one kind and contained Oil content detection method in greasy dirt water-washing process, as shown in figure 1, this method can include:
Step 101, oily sludge sample is placed in and washed in instrument;
Step 102, unilateral nuclear magnetic resonance apparatus is used outside washing instrument, using driving balanced pulse sequences as one-dimensional core Magnetic resonance measurement pulse train, Nuclear Magnetic Resonance Measurement is carried out to oily sludge sample, obtains the echo number of oily sludge sample According to;
Step 103, the echo string data according to oily sludge sample, determine the oil-containing in oily sludge sample water-washing process Rate.
Specifically, in embodiments of the present invention, it is that oily sludge sample is placed in washing instrument, is adopted outside washing instrument Nuclear Magnetic Resonance Measurement is carried out to oily sludge sample with unilateral nuclear magnetic resonance apparatus, can so reach the purpose of lossless detection. When it is implemented, in order to obtain more accurate measurement result, washing instrument can be placed on unilateral nuclear magnetic resonance apparatus On probe, and the sensitizing range of probe is directed at oily sludge sample position.Unilateral nmr probe uses external magnetic Field measurement mode, investigation depth are adjustable.
Unilateral nuclear magnetic resonance apparatus is used in the embodiment of the present invention, using driving balanced pulse sequences as one-dimensional nuclear magnetic resonance Pulse train is measured, Nuclear Magnetic Resonance Measurement is carried out to oily sludge sample, obtains the echo string data of oily sludge sample.Wherein Balanced pulse sequences are driven to measure pulse train for a kind of quick one-dimensional nuclear magnetic resonance, the sequence only needs the time of several seconds just A Nuclear Magnetic Resonance Measurement can be completed, the survey of oily sludge oil content can be quickly completed based on Nuclear Magnetic Resonance Measurement result It is fixed, so as to realize the oil content in on-line checking oily sludge sample water-washing process.Driving balanced pulse sequences can make oil-containing The echo amplitude of mud sample up-down vibration repeatedly, completing a signal acquisition using driving balanced pulse sequences only needs 10 millis The time of or so second.On-line checking is to when after the oil content in oily sludge sample water-washing process, can also draw out with washing Between elapse oily sludge oil content change curve.
In embodiment, when carrying out Nuclear Magnetic Resonance Measurement to oily sludge sample, driving balanced pulse sequences can be triggered Polarization window and echo acquirement window simultaneously act on make echo amplitude occur once vibrate, gather an echo data, circulation This process gathers one group of echo string data.Fig. 2 is the schematic diagram of driving balance (DE) pulse train in the embodiment of the present invention.Such as Shown in Fig. 2, driving balanced pulse sequences include two windows, and one is polarization window, alternatively referred to as longitudinal relaxation time (T1) Correlation window, one is echo acquirement window, alternatively referred to as T2 (T2) correlation window, corresponds to τ respectively1And τ2Two The individual duration.In actual mechanical process, the two windows act on simultaneously makes echo amplitude occur once to vibrate, and collection one is returned Wave number evidence, one group of echo string data can be collected by circulating this process.τ in Fig. 2DERepresented for half echo sounding time, 90X+Table Show 90 degree of pulses along the X-axis positive direction of three-dimensional cartesian coordinate system (X, Y, Z), 90X-Represent along three-dimensional cartesian coordinate system (X, Y, Z) X-axis negative direction 90 degree of pulses, 180Y+Represent the 180 degree along the Y-axis positive direction of three-dimensional cartesian coordinate system (X, Y, Z) Pulse.
In embodiment, drive the cycle-index of balanced pulse sequences can be according to the sample frequency of default echo string data It is determined that.For example, the cycle-index of driving balanced pulse sequences determines according to the sample frequency of the echo string data needed for experiment, typically The echo string data of the more collections of cycle-index is more, and the sample set data of oil content evaluation are more, and accuracy is also higher.
In embodiment, driving balanced pulse sequences make the echo amplitude of oily sludge sample up-down vibration repeatedly, these times The change of wave amplitude can reflect the longitudinal relaxation time of sample and the information of T2.Drive equalizing pulse sequence Row can quickly measure by single sweep operation to obtain the relaxation information of sample in 10 milliseconds or so of time, its rapidity measured Meet the requirement of chemical reaction flow on-line measurement.
After echo string data is obtained, first it can be determined according to echo string data vertical in oily sludge sample water-washing process To relaxation time and T2, further according to longitudinal relaxation time and T2, oily sludge sample water is determined Oil content during washing.The constituent of oily sludge is complicated, and the T1 and T2 of different component are different, in fact it could happen that different Component T1 is identical but situation that T2 is different, individually studies the problem of T1 and T2 may cause individual components to be difficult to and occurs, Influence the measurement explanation results of oil content.Due to the obtained echo data of driving balanced pulse sequences measurement while contain sample T1 and T2 information, therefore its better than traditional T1 edit pulses sequence that can only measure T1 and measure T2 CPMG pulse sequence.
Oil content detection method can include being total to based on one-dimensional nuclear-magnetism in the oily sludge water-washing process of the embodiment of the present invention The oil content modeling method for measurement data of shaking.Quick one-dimensional nuclear magnetic resonance pulse train can quickly be surveyed within the time of several seconds Measure to one group of echo string data, and oil content modeling method will go out sample according to this group of echo string data direct derivation Oil content.Specifically it is determined that during oil content in oily sludge sample water-washing process, PLS can be used to establish Echo string data and the correlation mathematical modeling of oil content, determine that oily sludge sample is water washed according to the correlation mathematical modeling Oil content in journey.
The correlation mathematical modeling of above-mentioned carry out oil content explanation is established based on PLS algorithm, will be more The one-dimensional echo amplitude data that kind oily sludge sample measures will use chemical method to survey as independent variable after different washing times The oil content data measured are as dependent variable, and so as to build oil content interpretation model, the oil content for completing pre-detection sample exists Line is tested.Fig. 3 is that the oily sludge content oil cut rate based on one-dimensional nuclear magnetic resonance measures modeled example figure in the embodiment of the present invention, such as Shown in Fig. 3, oily sludge sample collection is first carried out, then carries out oily sludge sample washing, carries out quick one-dimensional core respectively afterwards Magnetic resonance measurement, the one-dimensional echo amplitude data that a variety of oily sludge samples are measured are established independent variable collection, entered as independent variable Row soxhlet extraction methods measure, the oil content data that will be obtained after different washing times using chemical method measurement as dependent variable, Dependent variable collection is established, finally builds oil content interpretation model.
