The experiment parameter of the present invention is divided into operating parameter and performance parameter, and operating parameter sets for carrying out different operating modes, main
Operating parameter includes containing liquid concentration CiWith pressure ratio Pr.Performance parameter is good and bad for the performance characterizing separator, main performance parameter
There is separation efficiency EtΔ T drops with temperature.The measuring method of each parameter is as follows:
(1) enter to suck liquid concentration Ci
Entering to suck liquid concentration and be mainly used in simulating the moisture content of natural gas, there is difference because it produces region difference in natural gas water content rate
Different.CiValue has for the separation efficiency of separator the most directly to be affected.Need to preset during experiment into sucking liquid concentration Ci0,
Preset and calculated by following formula into sucking liquid concentration:
In formula, G1-liquid mass flow, kg/s；G2-gas mass flow, kg/s.
In view of gas flow regulation more difficulty, when presetting, keep gas mass flow G2Constant, by regulation G1Reach pre-
Fixed containing liquid concentration, it is provided with temperature and relative humidity for measuring separator inlet end fluid humidity at buffer 6 port of export, surveys
Definite value CiWith setting value Ci0It is qualified that error is i.e. considered as within 0.5%.
(2) pressure ratio Pr
Pressure ratio refers to supersonic speed separator inlet pressure PinWith dry gas outlet pressure PoutRatio.
In formula, Pr-pressure ratio；Pin-inlet pressure PinG2Gas mass flow, MPa；Pout-outlet pressure, MPa.
According to existing theory, pressure ratio has very important impact for the flow regime of air-flow in separator.Pressure ratio is excessive
Time, cause separator fluid velocity inside too high, airflow homogeneity is not enough, it is impossible to ensureing effectively carrying out of follow-up eddy flow, pressure ratio is excessive
Then meaning that gas energy loss is excessive, higher energy loss cannot meet being smoothed out of other techniques follow-up.When pressure ratio is less,
The gas energy flowing through jet pipe is limited, it is impossible to ensureing effectively to realize Supersonic Flow, the gas velocity of nozzle exit is less, at stream
Can not produce enough swirl strengths during the separated wing, gas-liquid separation is the most thorough.In the range of technique allows, select little pressure as far as possible
Ratio is tested.
(3) separation efficiency Et
Separation efficiency is to characterize the key index of supersonic speed cyclone performance, and separation efficiency refers to that the process containing humid gas is imitated by separator
Rate, characterizes by measuring liquid quality change, and it uses following formula to be measured calculating:
G-humid air mass flow, kg/s in formula；m2-outlet liquid quality, kg obtains by measuring leakage fluid dram liquid quality.
(4) temperature fall Δ T
Temperature fall is the another important indicator characterizing cyclone performance.Temperature fall refers to separator inlet temperature TinWith nozzle exit temperature
Degree TminDifference between (lowest temperature angle value).
Δ T=Tin-Tmin (4)
Δ T value is the biggest, then the minimum temperature that sign separator can reach is the lowest, and producible low temperature driving force is the strongest.Temperature drops
Δ T, by reading the temperature sensor numerical value in precalculated position, directly be can be shown that after being calculated by single-chip microcomputer.
In present invention experiment, the required physical quantity measured has: temperature T, flow Q, pressure P and throat velocity v.Institute in experiment
The digital independent having instrument and meter is all completed by single-chip microcomputer or computer software with record, reduces the impact of personal error.
In atomising device, respectively pressure, temperature, flow measurement device are set in gas circuit and fluid path, primarily to carry out entrance ginseng
Number regulation, it is contemplated that the finite capacity of single-chip microcomputer, this equipment component does not access single-chip microcomputer, uses traditional instrument measurement to show, real
Carry out manual record before testing beginning, during experiment, only need to ensure that its parameter remains stable.
Flow measurement: flow Q includes supersonic speed separator inlet humid air flow, liquid flow exit.
(1) entrance humid air traffic ingress humid air flow uses the metering of high-pressure natural gas effusion meter, and this effusion meter belongs to intelligence rotation
Enter vortex flowmeter, mainly utilize Karman vortex street principle to measure.For reducing the impact of measuring instruments, instrument installation site is according to producer
Suggestion, need to ensure that away from separator inlet front end the length having 5 times of pipe diameters is as buffering.
(2) liquid flow exit outlet liquid meter uses mass conversion.By arranging liquid collector at exit site, test
Weigh the liquid quality m (kg) collected after one-tenth, record experiment time t (s) used, liquid flow exit can be recorded.According to going out
Oral fluid weight number weigh in different ways, outlet liquid quality less time, use desiccant absorption, according to desiccant
Quality determination liquid flow exit；When outlet liquid quality is more, first weighs existing liquid quality, re-use desiccant dryness liquid collecting
Device, both superpositions quality calculates.
Temperature survey:
Temperature T is measured and is used temperature sensor measurement, in supersonic speed separator throat, nozzle exit, diffuser pipe entrance and air-liquid
Outlet is respectively provided with temperature sensor measurement, is measured record and the display of data by single-chip microcomputer.Nozzle throat and nozzle exit
Place's temperature sensor needs low temperature resistant high pressure, and working range is between-100 DEG C～50 DEG C, can bear 20MPa pressure.
Owing to throat dimension is the least, thus the less head of screw sensor of preferred dimension carries out throat's temperature survey.Screw thread is installed, and visits
Head stretch out the length of pipeline because throat diameter is different slightly difference.
In addition to throat and nozzle exit, the size at other positions is relatively big, and temperature requirement is the highest.Thus Choice of Sensors is easier,
General temperature sensor all can be competent at.Only should be noted sensor signal transmission and the mating of single-chip microcomputer.
Pressure measxurement:
Pressure P measures and uses pressure transducer, divides at nozzle exit, diffuser pipe entrance and separator gaseous phase outlet, liquid-phase outlet
Pressure transducer is not set.Pressure transducer measurement result carries out data by single-chip microcomputer and shows and record, the precision of pressure transducer
Requiring within 0.5%, range is 0～25Pa.Nozzle exit is relatively low due to temperature, should be noted the low temperature tolerance characteristics of pressure transducer.
Throat velocity is calculated:
Can throat reach velocity of sound is the key realizing separating, thus the measurement of throat velocity value is extremely important.Throat dimension is less,
Pressure is higher, and when directly carrying out tachometric survey, existing instrument is difficult to meet requirement, and the acquisition of throat velocity value need to be measured by other
Value converts.
The cryogenic property of supersonic speed separator has important reference value.Thus temperature sensor is set in throat and measures, larynx
Portion's measured temperature is designated as T*, fluid is considered as perfect fluid, according to aerodynamic relation, the speed of throat can be conversed
Value v.
In formula, k-adiabatic exponent, air takes 1.4；Rg-gas constant, air takes 287J/ (kg K)；T*-throat measured temperature K.
