Description
Technical field
The invention belongs to hot mixture state equation field of measuring technique, more particularly to a kind of measurement hydrogeneous mixing of high temperature
The apparatus and method of thing state equation.
Background technology
Hydrogen is a kind of clean energy resource.2005, Yan Qiuhui etc. had found to add biomass and coal slurry in supercritical water, can
Protium in coal slurry is continuously changed into hydrogen simple substance to separate out, the mixed working fluid containing hydrogen is generated.Experimental system is 650
DEG C, carried out under 25MPa, the working medium of generation contains 12% hydrogen, 8% carbon dioxide, 80% vapor.This mixed working fluid can quilt
For driving turbine, engine power generation is driven.And the design of the turbine, engine using this mixed working fluid is carried out, obtain
The problem of its state equation just turns into most direct and more crucial.
For the state equation measurement of hydrogen, mainly there are two methods at present：Burnett methods and constant volume area method.
2010, Sakoda etc. developed the device that hydrogen state equation is measured using Burnett methods.Its principle is foundation
State equation：PV=ZmRT, using the cavity of two fixed volumes, one is called sample cavity, and one is called expansion chamber.Sample cavity
There are two outlets, one is the pipeline for injecting sample, there is Valve controlling；Another is the pipeline for leading to expansion chamber, there is valve control
The flowing of system wherein mixture.There are three outlets on expansion chamber, one is the pipeline being connected with sample cavity, and another is bleeder pipe
Road, for discharging mixture in experiment, the 3rd is pipe outlet for vacuumizing.When testing beginning, into sample cavity
Injection is a certain amount of to contain hydrogen mixture, and the pressure of mixture is measured by pressure gauge, and the volume of mixture passes through calibration sample chamber
Volume measure, the temperature of mixture is measured by thermocouple.Unique unknown number is exactly the pressure of mixture initial temperature pressure
Contracting factor Z.This initial compression factor is obtained by following method fitting：Mixture is added, pressure initial in container is determined
After power, temperature, the valve between sample cavity and expansion chamber is opened, a certain amount of mixture is released into expansion chamber from sample cavity
Go, make sample cavity equal with the mixture pressure in expansion chamber.Turn off the valve between sample cavity and expansion chamber, it is ensured that sample
Mixture quality in chamber is constant, determines the pressure of mixture, temperature in now sample cavity.Afterwards, by the bleeder pipe of expansion chamber
Road is opened, and mixture therein is emptied, then expansion chamber is vacuumized, the shape for just adding sample into sample cavity is returned to
State.Then, it is again turned on connecting the valve of sample cavity and expansion chamber, by a part of mixture from sample cavity is discarded to expansion chamber
Go, make sample cavity equal with the mixture pressure in expansion chamber, close valve, it is ensured that the mixture quality in sample cavity is constant,
Determine pressure now in sample cavity, temperature.Afterwards, then by the atmospheric pipe of expansion chamber open, mixture therein emptied,
Then expansion chamber is vacuumized.So, circulated for several times, it is extremely thin until the gas pressure in sample cavity is minimum.Due to
Release a certain amount of mixture every time, the gas of releasing before accounting for the ratio of total gas be to be determined by expansion chamber with sample cavity volume ratio
, it is a constant.Mixture is believed that trend perfect gas when pressure is minimum, and its compressibility factor is intended to 1.So by institute
There is the data aggregate measured together, finding limit, you can obtain the compressibility factor Z of mixture original state.So, mixture exists
State equation in test scope just can be measured all.
Burnett methods can only determine state equation of the hydrogen at 200 DEG C, just occur more afterwards more than 200 DEG C
Serious hydrogen leakage problem, hydrogen is escaped from sample cavity and expansion chamber, makes measurement result inaccurate, and is had larger
Security risk.Therefore Burnett methods are not used to the measurement of 650 DEG C of hydrogeneous mixture state equation.
2012, Sakoda etc. developed the experimental provision that hydrogen state equation is measured using constant volume area method.Its principle is：
On the basis of Burnett methods, it is considered to sample cavity volume variation with temperature, the volume of sample cavity is much smaller than expansion chamber, is
About 1/10th of expansion chamber, first demarcate at different temperatures to sample cavity volume, then using with Burnett method classes
As method determine pressure and temp data.Finally, the state equation containing hydrogen mixture is calculated.Measuring, works as temperature
When reaching 800K, the volume of sample cavity about rises to 1.01 times of sample cavity volume under 400K.Measured using constant volume area method, hydrogen
The deviation of existing state equation is not more than 1% in 200 DEG C, 0-100MPa density and document.
Constant volume area method measuring state equation needs to obtain the state equation of low temperature under material in advance, or use perfect gas
State equation is carried out approximately, or the method directly weighed using balance weighs the quality of the larger the working fluid of molecular weight.But
For composition it is unknown contain hydrogen mixture, the state equation under its low temperature can not be obtained by simply measuring in advance, if used
Burnett methods are first measured, it is impossible to ensure the mixture in Burnett sample cavities and the mixture in constant volume area method container
Composition is identical；If calculated by equation for ideal gases, due to not fully meeting ideal at low temperature containing hydrogen mixture
Gas equation, can also make measurement result relatively large deviation occur；The molecular weight of each component containing hydrogen mixture is relatively low, adopts and weighs in the balance
The method of weight can also make experimental result relatively large deviation occur.
In summary, existing experimental method can only obtain state equation of the hydrogen below 500 DEG C and containing hydrogen mixture
State equation below 200 DEG C.Not yet there is researcher to propose the reality of 650 DEG C of measurement and its hydrogeneous mixture state equation of the above
Proved recipe method.

The pressure p in shuttle is measured with pressure sensor 11, temperature in use meter 1 measurement shuttle 1 in temperature T1。
Step 2：Reduce the heating power of electric heater 1, under making temperature and pressure in shuttle 1 gradually
Drop, and stably in a temperature.During temperature stabilization, the pressure p in shuttle is measured using pressure sensor 11i, use
Temperature T in the measurement shuttle 1 of thermometer 11i。
Step 3：Repeat step two M times, obtains M group pressure and temp data (p1i, T1i) (i=1,2,3 ..., M).Wherein
The temperature of M secondary controls shuttle 1 is T1M=T20。
Step 4：Electric heater 1 heats shuttle 1, the heating shuttle 22 of electric heater 24, temperature in use
The temperature in the temperature in one 9 measurement shuttles 1, the measurement shuttle 22 of thermometer 2 10 is counted, makes shuttle 1
T is always held at the temperature in shuttle 2220。
Step 5：Closing control valve 1, control valve 3 13, open control valve 2 12, make a part containing hydrogen mixture from
Shuttle 1 enters in shuttle 22.Using in the measurement of pressure sensor one 7,9 shuttle 1, shuttle 22
Pressure, after after pressure balance, use the pressure p in the measurement shuttle 1 of pressure sensor 12j；Closing control valve afterwards
2 12, control valve 3 13 is opened, shuttle 22 is vacuumized, closing control valve 3 13.
Step 6：The n times of repeat step five, obtain N number of pressure data p2j(j=1,2 ..., N)
Step 7：Closing control valve 1, opens control valve 2 12, control valve 3 13, and shuttle 1, sample are held
Device 22 is vacuumized, and changes the initial quality containing hydrogen mixture for being filled with shuttle 1, repeat step one to step 6 afterwards
Process, until obtaining sufficient amount of data.Last closing control valve 1, opens control valve 2 12, control valve 3 13, will
Shuttle 1, shuttle 22 are vacuumized, and instrument restPoses, and whole measurement process terminate.
