Description
Technical field
The utility model relates to the automatic analysis system of a kind of aviation kerosene its particular technology index of on-line analysis in the oil refining production run; Specifically a kind of miniature analyzer that is used for ZBX type boat coal freezing point on-line analysis system.
Background technology
Aviation kerosene (hereinafter to be referred as the boat coal) as aircraft engine fuel in use can be in temperature and hang down under the condition that reaches-50 ℃, stops up petroleum pipeline if the crystallization meeting occurs in the coal that at this moment navigates, and causes great aircraft accident.So the freezing point value is the most important quality index of boat coal.At present, the artificial assay method of main employing is analyzed boat coal freezing point in the oil refining production run, and then instructs production operation.Along with the raising of domestic each refinery automatization level and applying of advanced control system, artificial assay method is the time-consuming production run that lags behind greatly again, can not satisfy the production needs.At present, boat coal freezing point on-line analysis system is domestic belongs to blank.There is this product in several companies such as Germany, the U.S., Canada, and Germany, the U.S. mainly adopt and traditional add the mode that refrigerating machine combines with the internal heat electric refrigerator sample is lowered the temperature, and system is huge, costs an arm and a leg.External state-of-the-art have the advantages that to need not external refrigerating machine for adding the online freezing point analytic system of taking production, directly with thermoelectric cooling module sample lowered the temperature, and its quotation is every cover system 11.3 ten thousand U.S. dollars, and analyzer oil sample cavity volume is bigger, is the hundreds of milliliter.
In order to realize the coal on-line analysis system production domesticization of navigating, the applicant develops the explosion-proof intelligent online quality analysis system of energy automatic continuous analysis aviation kerosene freezing point in the oil refining production run, the i.e. online freezing point analytic system of ZBX type aviation kerosene.This analytic system is applicable to Ex d II CT
4The place of explosive-proof grade can be supporting with advanced control system, can improve the controlling level of process units, realizes " edge " operation, improves the product quality and the product yield of aviation kerosene.This analytic system does not need external explosion-proof type mechanical compress refrigerating machine, can reduce the analytic system cost greatly, avoids the maintenance workload of user to refrigerating machine.
Because boat coal freezing point temperature can reach below-60 ℃, belong to degree of depth cooling system, and the ZBX type boat coal freezing point on-line analysis system thermoelectric cooling module of applicant's development is directly to use 30 ℃ tap water that thermoelectric cooling module is dispelled the heat, so require thermoelectric cooling module to produce 90 ~ 100 ℃ the temperature difference.For this reason, the applicant develops the stepped level Four semiconductor heat of pagoda electric refrigerator, this refrigerator can produce the very big temperature difference, but its cooling power is little, be that carrying load ability is little, require technically further to reduce with the volume of fourth stage semiconductor heat electric refrigerator analysis cup that directly contact, analyzer, the smaller the better, thereby the objective requirement of miniature analyzer is developed in proposition.
Analyzer is the core component of ZBX type boat coal freezing point on-line analysis system.In analyzer, to finish refrigeration cooling to tested oil sample, whether produce crystallization after the continuous monitoring oil sample is lowered the temperature, will be determined this temperature when oil sample cools to when crystallization point produces crystallization, the multinomial functions such as temperature freezing point temperature value when stopping refrigeration at once and measuring oil sample intensification post crystallization disappearing.For the purpose of the analyzer microminiaturization that realizes ZBX type boat coal freezing point on-line analysis system, the miniature analyzer that can satisfy the demand, volume is little is developed in applicant's experiment of tackling key problems repeatedly finally.
The utility model content as mentioned above, the technical problems to be solved in the utility model is to provide a kind of miniature analyzer of rational in infrastructure, the small and exquisite ZBX of the being used for type boat of volume coal freezing point on-line analysis system.
The utility model solves the problems of the technologies described above the technical scheme of taking: a kind of miniature analyzer of the ZBX of being used for type boat coal freezing point on-line analysis system, comprise the analysis cup, it is characterized in that: analyze cup and roughly be provided with through hole in the centre position, the two ends of through hole are connected with oil-in, oil-out respectively; Through hole stage casing, hole wall make an appointment with the arc surface of half to be provided with the surface of internal cavity black layer, and device has the direct reflection sheet on second half arc surface of hole wall; The position corresponding with the direct reflection sheet is provided with the cross-drilled hole of vertical perforation with through hole on the analysis cup, Fibre Optical Sensor is housed in the cross-drilled hole, the advancing chevilled silk and go out chevilled silk and be connected with the two ends of direct reflection sheet respectively of Fibre Optical Sensor, advance the chevilled silk other end and infrared incident light joins, go out the chevilled silk other end and infrared reception light joins; Analyze on the cup and also be provided with counterbore, temperature detecting resistance is installed in the counterbore.
Temperature detecting resistance is the thermometric platinum resistance.
As of the present utility model perfect, for two ends and oil-in, the oil-out that makes through hole is connected firmly, the two ends of through hole are fixed with fuel inlet fitting and delivery connection respectively; In like manner, the cross-drilled hole outer end is fixed with fibre-optical splice; The counterbore outer end is fixed with the resistance joint.
The aluminium block that analysis cup of the present utility model is 20 * 20 * 8mm is made, it only is 0.1ml that oil sample detects cavity volume, promptly realized online detection to oil sample, and external like product cavity volume is tens milliliters, thereby the utility model is rational in infrastructure, volume is small and exquisite, analyzes repeatable accuracy and reaches about 0.7 ℃.Overtesting chamber test of this miniature analyzer and production scene are checked for a long time, have dependable performance, stable, measure advantages such as accurate; It can be supporting with the advanced control system of each refinery, thereby promote the level of China's oil refining robotization control.
The course of work of the present utility model: oil sample enters the analysis cup, at first " heating " displacement last cycle oil sample, washing analysis cavity and be full of new oil sample then, after regularly the oil-feed program is finished, analytic system enters the refrigeration temperature-fall period, at this moment oil sample is lowered the temperature by thermoelectric cooling module, when after crystallization appears in oil sample, disappearing again, detect the peak change of light intensity by Fibre Optical Sensor, and note corresponding freezing point value by platinum resistance, system stops refrigeration, and trigger heats up, the automatic analysis that enters following one-period again.Finish automatic oil-feed oil extraction, cooling automatically, automatic detection methods of a series of automatic controls such as freezing point temperature when measuring crystallization point temperature when crystallization occurring and crystallization and disappear automatically by whole ZBX type boat coal freezing point on-line analysis system, realize fast, accurately, the requirement of METHOD FOR CONTINUOUS DETERMINATION.
