Description
Technical field
The utility model relates to the in-line analyzer sampling apparatus of analysis reactor in petroleum chemical industry, and what be specifically related to is on-line chromatograph analyser sampling apparatus.
Background technology
Pyrolysis Furnance System in Ethylene Plant is that to mix naphtha, hydrogenation tail oil, lighter hydrocarbons, Cycle ethane and propane be raw material, by injecting dilution steam generation, generates mixed pyrolysis gas under the effect of high-temperature heating.The adjustment of pyrolysis furnace parameter is the analysis data by on-line chromatograph analyser, judges each component concentration of pyrolysis gas in reactor, thereby the steam injection of pyrolysis furnace, temperature control etc. is adjusted.In raw material cracking process, cracking severity is that ethylene/propene mass ratio is the important indicator of controlling pyrolysis furnace operation, by regulating this index, can control ethene, propylene yield ratio and quantum of output, too high cracking severity can affect the operation life of pyrolysis furnace, too low cracking severity can affect the product yield of output, increase pyrolysis furnace and obtain energy consumption, affect cost.So the even running of on-line chromatograph analyser is most important to Pyrolysis Furnance System in Ethylene Plant.
On-line chromatograph analyser is in order to detect cracking stock, to be converted into the yield of cracking product ethene, propylene, to weigh the effect of cracking process, has very high selection coefficient, is suitable for the measurement to a plurality of components to be analyzed in polycomponent mixed gas.Pyrolysis gas in-line analyzer is different from other type instrument, and sampling is simple, and maintenance requirement is also very high.As shown in Figure 1, existing analysis reactor on-line chromatograph analyser sampling apparatus is connected the sampling line of quarter bend tubular type between sample flow line 1 and chromatograph 7, be that sampling line is by a VERTICAL TUBE with transverse tube is integrated forms, sampling line inlet end place arranges sample valve 2, instrument airduct line 6 is connected to chromatograph 7, owing to containing a large amount of heavy oil in pyrolysis gas, moisture and impurity, in sampling process, the most of impurity of sampling pre-processing device energy elimination and the greasy dirt of chromatograph, but also have partial impurities to circulate at sampling line with sample gas, after instrument long-time running, can cause sampling line to stop up at right-angle bend place, with the impurity in up-to-date style gas, can endanger chromatographic column, reduce the serviceable life of chromatographic column, cause analyze interrupting or analyze undesired.
Summary of the invention
The purpose of this utility model is to provide on-line chromatograph analyser sampling apparatus, and it can stop up and stop up inconvenient the asking of rear cleaning for solving the sampling line of existing analysis reactor on-line chromatographic analysis instrument sampling apparatus.
The utility model solves the technical scheme that its technical matters adopts: this on-line chromatograph analyser sampling apparatus arranges VERTICAL TUBE, impurity case, transverse tube between sample flow line and chromatograph; VERTICAL TUBE one end is connected with sample flow line, and one end is connected to the end face of impurity case, and transverse tube one end is connected to top, impurity case side, and the transverse tube other end connects chromatograph, and inlet porting valve in VERTICAL TUBE, arranges outlet valve on transverse tube; The end face of impurity case is connecting water pipe also, and water valve is set on water pipe, and the bottom surface of impurity case is provided with blowoff valve; VERTICAL TUBE inlet end place arranges sample valve, and instrument airduct line is connected to chromatograph.
In such scheme, on instrument airduct line, sintered filter is installed, sintered filter can filter a small amount of impurity in instrument wind, avoids entering chromatogram, pollutes chromatographic column, and cleaning is convenient, has guaranteed the normal operation of chromatograph.
Beneficial effect:
During the utility model work, impurity in sample gas is stacked into the bottom of impurity case gradually with the operation of instrument, estimate at after impurities accumulation after a period of time, and inlet valve and outlet valve are closed, open water valve and blowoff valve, in impurity case, pass into hot water or steam, the impurity dirt in impurity case can be discharged from blowoff valve, the impurity of accumulation thoroughly can be removed, to guarantee chromatograph, normally work, this cleaning work simultaneously only needs controlled valve just can complete, and scale removal process is without dismounting, very convenient.
