Description
Technical field
The present invention relates to a kind of crude oil and fuel oil sediments determinator.
Background technology
The present existing device that is used for measuring crude oil and fuel oil contents of precipitate by GB/T6531-86 " crude oil and fuel oil sediments determination method (extraction process) " with the toluene extracting; Mainly form by heating arrangement (generally being electric heater) and extraction plant; Said extraction plant comprises extraction flask, condensing coil, extracting sleeve and bush support; Said condensing coil is fixed on the bottle cap of extraction flask; Its two ends pass bottle cap and connect liquid coolant; Remainder is positioned at extraction flask, and bush support hangs in the extraction flask through metal wire rod and in condensing coil and extraction flask between the solvent liquid level of splendid attire, the extracting sleeve places in the described bush support.The said equipment is a principle of utilizing evaporation, cooling; Guarantee the solvent toluene constantly crude oil or the fuel oil of splendid attire in the irrigation sleeve, wash the oil plant organic component off after, sediment is stayed in the sleeve; When the solvent that in sleeve, oozes was colourless, extracting was 30 minutes again; The liquid level of the oil in the whole process middle sleeve and the potpourri of toluene should be no more than downward 20 millimeters position, sleeve top.Utilize said apparatus when detecting, because the solvent (toluene) of cooling directly splashes into from condensing coil the sleeve, this can make the organic component in crude oil or the fuel oil upwards spread along sleeve wall; Its backwashing manner can be described as and soaks rather than flushing truly for from bottom to top, thereby the time that causes washing is longer; Generally speaking; The time of detecting a sample is at least 20～24h, even longer, and this directly causes staff's detection efficiency low; Moreover because the liquid level of the potpourri of oil plant and toluene is higher, this also can cause the oil plant organic component on sleeve wall top to be not easy to rinse well, influences the degree of accuracy of testing result.In addition; Because the temperature correlation at the temperature of extraction flask bottle wall and the bottle end is bigger; The evaporation rate of solvent is slower like this, and a lot of solvent vapo(u)rs are cooled off by extraction flask (like parts such as bottle walls) when not arriving condenser surface, thereby causes the speed that splashes into the extracting sleeve after the solvent vapo(u)r condensation slow excessively; This also is a long reason of existing pick-up unit flush time, and influence is particularly evident when temperature is low.
Summary of the invention
The technical matters that the present invention will solve provides crude oil and the fuel oil sediments determinator that a kind of flush time is short, detection efficiency is high, testing result is accurate and precision is high.
Crude oil of the present invention and fuel oil sediments determinator; Mainly be made up of heating arrangement and extraction plant, said extraction plant comprises extraction flask, condensing coil, extracting sleeve and bush support, and said condensing coil is fixed on the bottle cap of extraction flask; Its two ends pass bottle cap; Remainder is positioned at extraction flask, and bush support hangs in the extraction flask, and the extracting sleeve places in the described bush support; Different with prior art is: said extraction plant also comprises a guiding device, and this guiding device comprises that a diameter is slightly smaller than the circular fair water fin of extracting sleeve diameter and the web member of a connection fair water fin and condensing coil.Through adding guiding device; Make by the condensed solvent of condensing coil along web member through the fair water fin water conservancy diversion to the barrel of extracting sleeve, realize backwashing manner from top to bottom, can shorten flush time greatly; Improve detection efficiency, and can guarantee the accuracy and the high precision of testing result simultaneously.
In the technique scheme,
For making solvent on the fair water fin can flow to the barrel of extracting sleeve faster, high in the middle of preferably fair water fin being designed to, the low recess shape of falling all around promptly should make the longitudinal profile of fair water fin be middle high, the low arcwall face in two ends.
Organic substance from flushing extracting sleeve wall considers that the hanging position of said fair water fin is comparatively suitable with the middle and upper part that is positioned at the extracting sleeve, preferably is positioned at the top end opening place of extracting sleeve.
Described web member can be thread or rod-like members, tinsel for example, and its material should be corrosion resistant stainless steel, nickel-chrome etc. certainly.The fair water fin that suspension is good should not favour arbitrary side, and therefore an end wiry preferably is wound in the lowermost of condensing coil, and the other end then is wound in the center of circle of fair water fin.This makes condensed solvent flow on the fair water fin along tinsel, can when solvent drips, the sample in the extracting sleeve not spattered to barrel, more can not spill outside the extracting sleeve, avoids detecting error.
For the flushing dose of the water that further guarantees to receive on the extracting sleeve wall is uniform; Can on fair water fin, radially offer the groove that twice at least run through fair water fin thickness; The reference position of said groove is the circumference of fair water fin, has distance between its final position and the center of circle.The shape of said groove can be quadrilateral or triangle, is preferably triangle, when groove be shaped as triangle the time, this triangle preferably has two summits to be positioned on the circumference of fair water fin.
Not arriving condensing coil for fear of the steam of solvent is that the too much bottle wall by extraction flask cools off, and improves the speed that splashes into the extracting sleeve after the solvent vapo(u)r condensation, and heat-insulation layer can or all be set on extraction flask top.Said heat-insulation layer is processed by asbestos or foamed material.The Erlenmeyer flask that extraction flask is normally general.Described part is provided with heat-insulation layer, can be on the conical flask wall of extraction flask, to wrap up insulation material, wherein reserves and observes viewport or the observation groove that condensing solvent flushing extracting sleeve oozes the color of water; Heat-insulation layer all is set, and then can be on the bottle wall of whole extraction flask, to wrap up insulation material, heat-insulation layer is taken off when needing to observe the flushing situation again.
Heating arrangement described in the such scheme is the heating arrangement of conventional use in existing crude oil and the fuel oil sediments determinator, like electric heater etc.
Device according to the invention meets the requirement of GB/T6531-86 and ISO3735.The applicant carries out sample detection with device according to the invention, find that only need 3～5h to accomplish the detection time of a sample, and testing result is accurate, and precision is high.
Compared with prior art, the invention has the advantages that:
1, through adding the guiding device of forming by fair water fin and web member; Make by the condensed solvent of condensing coil along the web member water conservancy diversion to the barrel of extracting sleeve; Realize backwashing manner from top to bottom, can shorten flush time greatly, need 20～24h to reduce to 3 present～5h by sample of original detection; Improve detection efficiency widely, and can guarantee the accuracy and the high precision of testing result simultaneously;
2, on fair water fin, radially offer the groove that twice at least run through fair water fin thickness, the flushing dose of the water that further guarantees to receive on the extracting sleeve wall is uniform;
3, heat-insulation layer is set on extraction flask; Guarantee rapid solvent evaporation; Avoiding the steam of solvent is that the too much bottle wall by extraction flask cools off not arriving condensing coil, splashes into the speed of extracting sleeve after the condensation of raising solvent vapo(u)r, further reduces the time of flushing;
4, because the shortening of flush time has been practiced thrift heating electricity consumption and the cooling water in a large amount of testing processes when improving detection efficiency, not only reduce testing staff's labour intensity, also practiced thrift the energy greatly.
