Abstract
The present invention relates to an automatic analysis device for gas in top space of canned rock swarf and mud, which belongs to an analysis detection device in the petroleum geology chemical industry. A sample with two sampling holes is canned on a sample feeding rod which can be controlled to freely move up and down. When the sample feeding rod moves upwards, sampling probes enter the sampling holes to push sealing cushions, and thereby, carried gas automatically carries sample gas to a chromatographic column to be separated, and light hydrocarbon constituents in the sample are detected by a detector. When the sample feeding rod is withdrawn, the sampling holes arranged on a sample can are automatically closed. The automatic analysis device is suitable for detecting various solid, liquid, gaseous petroleum chemical samples. Because the automatic analysis device can automatically detect sample gas, the automatic analysis device has the advantages of convenient and suitable detection, good repeatability and high precision. The automatic analysis device can detect rock swarf or mud samples on petroleum well drilling sites, and thus, the detection efficiency can be greatly enhanced.
Description
Technical field the invention belongs to a kind of oil geology chemical industry analysis and detection device.
Background technology is present, when measuring petroleum gas light hydrocarbon component content, be to pack in the jar of sealing mostly, need when measuring its lighter hydrocarbons content on jar, punch that extracting gases is expelled in the gas chromatograph and analyzes from jar then with containing the landwaste of sample gas or mud sample.The invention provides a kind of automatic headspace sampling device, will contain the landwaste of sample gas or mud sample and pack into behind the special sample pot, can auto injection and measure its lighter hydrocarbons content.
Summary of the invention the present invention is that the sample pot that will have two thief holes is contained in and can controls on the sample feeding rod that easy on and off moves, when sample feeding rod is boosted, the sampled pin jacking of thief hole, back down sealing gasket, make carrier gas carry sample gas automatically, deliver in the chromatographic column and separate, by light hydrocarbon component in the detecting device test sample; When sample feeding rod is drawn back, sample pot top thief hole auto-closing.
