Abstract
The invention relates to a special oil-resistant and anti-pollution chromatographic column for transformer oil. The special oil-resistant and anti-pollution chromatographic column is characterized by comprising a tube body, supporters and stainless steel nets, wherein the supporters are used for chromatographic analysis; the stainless steel nets are arranged at both ends of an inner cavity of the chromatographic column; the supporters are filled into the inner cavity between the stainless steel nets at the two ends, and the diameter of each supporter is smaller than the hole diameter of each stainless steel net. The special oil-resistant and anti-pollution chromatographic column has the advantages that the structure is reasonable and practical, the column efficiency is high, the separating property is good, the oil-resistant and anti-pollution properties are good, and the special oil-resistant and anti-pollution chromatographic column belongs to the special chromatographic column for the detection of the transformer oil.
Description
Technical field
The present invention relates to a kind of chromatographic column for gas chromatographic analysis, particularly a kind of transformer oil special oil resistant antipollution chromatographic column, oil resistant, anti pollution property are strong, are applicable to the gas chromatographic analysis to transformer oil in electric system.
Background technology
Existing transformer oil chromatographic post generally conventional stainless-steel tube or the interior carbonaceous molecular sieve Stationary liquid of filling of pipe is formed, and pipe becomes U-shaped or spirality.General column jecket internal diameter is 2 millimeters, and column jecket length is generally 1 meter to 3 meters.But there is chromatographic column not oil resistant, easily contaminated, thus the problem such as serviceable life is short.Along with the development of society, the expansion construction of electric system, need the transformer detected to get more and more, existing traditional transformer oil chromatographic post can not meet the demands.
Summary of the invention
The object of the invention is to make up the deficiencies in the prior art, a kind of transformer oil special oil resistant antipollution chromatographic column being provided, effectively carrying chromatographic column high oil resistance, resistance tocrocking, thus improve its serviceable life.
The present invention is achieved in that a kind of transformer oil special oil resistant antipollution chromatographic column, it is characterized in that: described chromatographic column comprises body, for the carrier of stratographic analysis and stainless steel cloth; Be provided with stainless steel cloth at the two ends of the inner chamber of described chromatographic column, the inner chamber between the stainless steel cloth at described two ends is filled with the carrier that particle diameter is less than described stainless steel wire screen distance.
The outer diameter of the body of described chromatographic column is 3 ~ 4 millimeters, and wall thickness is 1 ~ 1.2 millimeter, and the length of described chromatographic column is 1 ~ 1.5 meter; The diameter of described stainless steel cloth matches with the inner diameter of body.Described body adopts stainless steel body.Described carrier is the potpourri of the modified porous superpolymer of 60 ~ 80 object and carbonaceous molecular sieve, described modified porous superpolymer adopts the hydrochloric acid through 5% to carry out the porous polymer of chemical modification process, described carrier is 3.15 ~ 9.23 milliliters at the volume of the lumen loading of chromatographic column, wherein the volume ratio of modified porous superpolymer accounts for 60% is 1.89 ~ 5.5 milliliters, and the volume ratio of carbonaceous molecular sieve is 40%.
The invention has the beneficial effects as follows: the present invention is that a kind of transformer oil detects special color analysis of spectrum post, simple and reasonable for structure, practical, and oil resistant, anti pollution property are strong, long service life, the chromatographic column solving prior art not oil resistant, easily contaminated, thus the problem such as serviceable life is short, meet the user demand of user.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of chromatographic column of the present invention.
In figure: 1, body; 2, carrier; 3, stainless steel cloth; 4, inner chamber.
Embodiment
With reference to the accompanying drawings, a kind of transformer oil of the present invention special oil resistant antipollution chromatographic column comprises body 1, for the carrier 2 of stratographic analysis and stainless steel cloth 3.At the two ends of the inner chamber 4 of described chromatographic column, stainless steel cloth 3 is installed, in the inner chamber 4 between the stainless steel cloth 3 at described two ends, is filled with the carrier 2 that particle diameter is less than described stainless steel wire screen distance.
The outer diameter of the body 1 of described chromatographic column is 3 ~ 4 millimeters, and wall thickness is 1 ~ 1.2 millimeter, and the length of described chromatographic column is 1 ~ 1.5 meter, and the diameter of described stainless steel cloth 3 matches with the inner diameter of body 1.Described body 1 adopts stainless steel body.Described carrier 2 is the potpourri of the modified porous superpolymer of 60 ~ 80 object and carbonaceous molecular sieve, described modified porous superpolymer adopts the hydrochloric acid through 5% to carry out the porous polymer of chemical modification process, described carrier 2 is 3.15 ~ 9.23 milliliters at the volume of the lumen loading of chromatographic column, optimum is 9.23 milliliters, wherein the volume ratio of modified porous superpolymer is 60%, and carbonaceous molecular sieve volume ratio is 40%.Assembling process of the present invention: when filling 60 ~ 80 object carrier 2 in the inner chamber 4 of chromatographic column, one end of chromatographic column first uses stainless steel cloth 3 by the ferrule of chromatographic column, then one end of chromatographic column is connected vacuum pump, the other end of vacuum pump then connects funnel class container, is then filled into uniformly in the inner chamber 4 of chromatographic column by described carrier.Unload vacuum pump and funnel class container after filling completes, this end of chromatographic column is also sealed with stainless steel cloth 3, completes the assembling of chromatographic column.
Embodiment:
When loading carrier 2 in chromatographic column inner chamber 4, first load the carbonaceous molecular sieve of 1.9 milliliters, recharge the modified porous polymeric thing of 2.8 milliliters afterwards, and ensure that the carrier of two kinds of potpourris of filling is distributed in the inner chamber 4 of whole chromatographic column uniformly, and between particle, degree of tightness is moderate.In filling process, chromatographic column does not connect the vacuum pump long time, in order to avoid cause the carrier particulate interspaces for stratographic analysis of filling too small.The diameter of stainless steel cloth 3 that chromatographic column is arranged matches with the intracavity diameter of chromatographic column, can not be excessively loose, in case stainless steel cloth 3 and the carrier 2 for stratographic analysis are produced by boasting under carrier gas drives, also can not tension, so as not to cause during work chromatographic column front press too large.Also need after having loaded carrier 2 could use through overaging, aging is to remove remaining solution and volatile material in inner chamber 4, immobile liquid also can be made more uniformly to be distributed on the inwall of carrier and body 1 simultaneously.Aging method adopts gas flow method, chromatographic column inlet end during filling carrier is connected with the injection port of instrument injector, the other end of chromatographic column does not connect detecting device, then logical carrier gas is warming up to 180 degrees Celsius with 5 degree celsius temperature per minute and carries out aging more than eight hours, just normally can use chromatographic column.During use, transformer oil of the present invention special oil resistant antipollution chromatographic column needs the injection port aging air intake opening being connected injector in use, otherwise can not play the characteristics such as oil resistant antipollution.
