Based on the present invention, be aided with corresponding power set and measuring apparatus, build experiment porch, for studying impact and the checking correlation theory of separator parameter stream field.
The parameter of experiment is divided into operating parameters and performance perameter.Operating parameters is for carrying out different operating mode settings, and main operating parameters comprises containing liquid concentration C
iwith pressure ratio P
r.Performance perameter is good and bad for the performance characterizing separator, and main performance perameter has separation efficiency E
tΔ T falls with temperature.The measuring method of each parameter is as follows:
(1) enter to suck liquid concentration C
i
Enter to suck the water ratio that liquid concentration is mainly used in simulating Sweet natural gas, natural gas water content rate there are differences because it produces region difference.C
ivalue has for the separation efficiency of separator very directly to be affected.Need preset during experiment into sucking liquid concentration C
i0, preset and calculated by following formula into sucking liquid concentration:
In formula, G
1---liquid mass flow kg/s
G
2---gas mass flow kg/s
Consider that gas flow regulates comparatively difficulty, when presetting, keep gas mass flow G
2constant, by regulating G
1reach predetermined containing liquid concentration.
Temperature Humidity Sensor is provided with for measuring separator inlet end fluid humidity, measured value C at snubber exit end
iwith set(ting)value C
i0it is qualified that namely error is considered as within 0.5%.
(2) pressure ratio P
r
Pressure ratio refers to supersonic speed separator inlet pressure P
inwith dry gas top hole pressure P
outratio.
According to existing theory, pressure ratio has very important impact for the flow state of air-flow in separator.When pressure ratio is excessive, cause separator fluid velocity inside too high, airflow homogeneity is not enough, and cannot ensure effectively carrying out of follow-up eddy flow, pressure ratio is excessive, and mean that gas energy loss is excessive, higher power loss cannot meet carrying out smoothly of other techniques follow-up.When pressure ratio is less, the gas energy flowing through jet pipe is limited, and can not ensure effectively to realize Supersonic Flow, the gas velocity of nozzle exit is less, and can not produce enough swirl strengths when flowing through and being separated the wing, gas-liquid separation is not thorough.In the scope that technique allows, select little pressure ratio to test as far as possible.

Δ T value is larger, then characterize the separator minimum temperature that can reach lower, producible low temperature motivating force is stronger.Temperature falls Δ T by reading the temperature sensor numerical value in predetermined position, directly can show after being calculated by micro-chip.
Supersonic speed separator experimental installation can be divided into atomisation unit, tripping device, measuring apparatus and collection device according to function.
Atomisation unit comprises air compressor machine, water pump, snubber, pressure maintaining valve, water tank and atomizing nozzle etc., and arranges metrical instrument at pipeline position.
Tripping device mainly refers to supersonic speed separator, and tripping device comprises the piping attachments such as pipeline, valve, reducing.
Measuring apparatus mainly refers to the pressure, temperature sensor and the transmitter that are preset in everywhere, and for the micro-chip that records and show and computer.
Collection device mainly comprises dry gas storage tank and water tank and corresponding pepeline fittings.
(1) equipment is arranged in optional test place, according to by leading secondary order, installing separator model machine, discharged atomisation unit position successively, gas collection equipment and liquid collecting device location are ranked at exit end at inlet end from mid-way.Combine adjustable dimensional change according to separator, reserved sufficient space, select the assembling of the separator model of intermediate parameters to fix each device, surveying instrument instrument finally loads predeterminated position.Impact each other need be considered when equipment is installed, the basis of guaranteeing not interfere makes installation site compact as far as possible.Water pump and air compressor machine position should stagger as far as possible, notice that equipment vibrations are on the impact of experiment.
(2) each metrical instrument requires in connecting system by metrical instrument calibrating to specifications, initialize, calibration operation state, checks whether range and precision meet the demands, and guarantees that signal measurement is normal with transmission.
(3), before air tight test experiment starts, airtight test need be carried out.Whether closely after each device is in place, pass into low-pressure air inspection, check separator each connecting portion No leakage, check measurement instrument installs whether close and firm, checks whether pipe joint position seals and puts in place.
(4) ambient moisture measures and affects to get rid of and arranges wet bulb thermometer at experimental site, measures ambient moisture with for referencial use.Simultaneously for guaranteeing the accurate measurement of separation efficiency, arrange moisture eliminator to be opened/closed respectively in collection device exit, moisture eliminator mainly uses the method for physical adsorption, gets rid of the impact of ambient moisture on experiment.Need to close when formal experiment.
(5) security that air pressure is tested is considered in the start and stop of device, and except air compressor machine and water pump, in experiment, the keying of other devices is all by micro-chip or computer remote operation.At the end of experiment, first switch off the pump and valve, air compressor machine works on, and utilizes air pressure to be discharged by intrasystem wet air.
In experiment, the required physical quantity measured has: temperature T, flow Q, pressure P and throat velocity v.In experiment, the digital independent of all appts instrument is all completed by micro-chip or computer software with record, reduces the impact of personal errors.
In atomisation unit, respectively pressure, temperature, flow measurement device are set in gas circuit and fluid path, mainly in order to carry out suction parameter adjustment, consider the finite capacity of micro-chip, this equipment component does not access micro-chip, use traditional instrument measurement display, before experiment starts, carry out manual record, during experiment, only need ensure that its parameter remains stable.
Flow Q comprises supersonic speed separator inlet wet air flow, liquid flow exit.
(1) entrance wet air traffic ingress wet air flow adopts the metering of high-pressure natural gas under meter, and this under meter belongs to intelligent precession spiral flowmeter, mainly utilizes Karman vortex street principle to measure.For reducing the impact of metrical instrument, instrument installation site is advised according to producer, need ensure 5 times of length to pipe diameter as buffering apart from separator inlet front end.
(2) liquid flow exit outlet liquid meter adopts mass conversion.By arranging liquid collector at outlet position, tested the liquid mass m (kg) that rear weighing is collected, record experiment time t (s) used, can record liquid flow exit.According to outlet liquid mass number weigh in different ways, outlet liquid mass less time, use siccative absorption, according to siccative quality determination liquid flow exit; When outlet liquid mass is more, first weigh existing liquid mass, re-use desiccant dryness liquid collector, both superpositions quality calculates.
Temperature measurement T measures use temperature sensor measurement, at supersonic speed separator throat, nozzle exit, diffuser pipe entrance and gas, liquid outlet set temperature sensor measurement respectively, is carried out record and the display of take off data by micro-chip.Nozzle throat and outside nozzle temperature sensor need low temperature resistant high pressure, and working range is between-100 DEG C ~ 50 DEG C, can bear 10MPa pressure.
Because throat dimension is very little, the screw head sensor that thus preferred dimension is less carries out throat's temperature survey.Screw thread is installed, and the length that probe stretches out pipeline is slightly difference because throat diameter is different.
Except throat and nozzle exit, the size at other positions is comparatively large, and temperature requirement is not high.Thus Choice of Sensors ratio is easier to, and general temperature sensor all can be competent at.Only should be noted sensor signal transmission and the mating of micro-chip.
Pressure survey pressure P is measured and is used pressure transmitter, arranges pressure transmitter respectively at nozzle exit, diffuser pipe entrance and separator gaseous phase outlet, liquid-phase outlet.Pressure transmitter measuring result carries out data presentation and record by micro-chip, and the accuracy requirement of pressure transmitter is within 0.5%, and range is 0 ~ 20MPa.Nozzle exit is lower due to temperature, should be noted the low temperature tolerance characteristics of pressure transmitter.
Can throat velocity measuring and calculating throat reach velocity of sound is the key realizing being separated, and thus the measurement of throat velocity value is extremely important.Throat dimension is less, and pressure is higher, and when directly carrying out velocity survey, existing instrument is difficult to meet the demands, and the acquisition of throat velocity value need be converted by other observed values.
The low-temperature performance of supersonic speed separator has important reference value.Thus measure at throat's set temperature sensor, throat's measured temperature is designated as T*, and fluid is considered as perfect fluid, according to aerodynamics relation, can converse the velocity amplitude v of throat.
In formula, k---specific heat ratio, air gets 1.4
R
g---gas law constant, air gets 287J/ (kgK)
T*---throat measured temperature K
