Abstract
The utility model discloses a novel chromatographic column special for coal gas component analysis and belongs to the application field of gas chromatographic techniques. The novel chromatographic column is mainly used for analysis on components in coal gas. The novel chromatographic column comprises glass wool, an external column pipe, an internal column pipe, an external column filling supporter and an internal column filling supporter. After the internal column filling supporter is filled with the internal column pipe, the internal column pipe is arranged into the outer column pipe, the left space of the external column pipe is filled with the external column filling supporter, and the two ends of the external column pipe are plugged by the glass wool. The novel chromatographic column is convenient to use, and contents of the main components of the coal gas can be accurately analyzed through one-time sample introduction.
Description
Technical field
The utility model belongs to the gas chromatographic technique application, for seven kinds of components of oxygen, nitrogen, carbon monoxide, methane, carbon dioxide, ethane, ethene of measuring coal gas.
Background technology
Coal gas, be a kind of gaseous fuel or gas raw material that coal draws as raw material of take, and the method difference according to producing, can be divided into water gas, semiwater gas, coke-oven gas, blast furnace gas etc.No matter any coal gas, its principal ingredient is all oxygen, nitrogen, carbon monoxide, methane, carbon dioxide, ethane, ethene etc.For gas analysis, a kind of is according to the analytical approach in standard GB/T/T 10410-2008, needs three chromatographic columns, minute three sample introductions to be analyzed the key component in coal gas.Second method is to adopt the mode of switching between two root chromatogram columns to carry out gas analysis, although this analysis mode can the whole gas composition of single injected sampling analysis, but because needs are held switching time, therefore the technical requirement to the laboratory technician is higher, and after wherein once a root chromatogram column damages the replacing New GC column, just must again find switching point, this just needs professional personnel to complete, and to the user, brings a lot of inconvenience.
Summary of the invention
In order to detect the key component of coal gas, the chromatographic column specially that the utility model provides a kind of gas composition to analyze, can single injected sampling detect the key component of coal gas.
The technical scheme that the utility model adopts for achieving the above object is: adopt the structure of sleeve column, by the synthetic root chromatogram column of two root chromatogram columns, be divided into inner prop, column jacket and fill carrier.
Described cover rod structure is comprised of two different stainless-steel tubes of diameter.
The stainless-steel tube that described inner prop column jecket is diameter 2mm, column filling carrier in filling in pipe, the stainless-steel tube that the column jacket column jecket is diameter 4mm, fill outer column filling carrier in pipe, and column jacket column jecket two ends port is blocked with glass fiber.
In the utility model, sample can enter respectively inner prop and column jacket, and the effect of inner prop is oxygen separation, nitrogen, carbon monoxide, methane, and the effect of column jacket is separating carbon dioxide, ethane, ethene.
The beneficial effects of the utility model are: can analyze key component by single injected sampling, reduced the number of times of sample introduction, reduced the analytical error inaccurate produced by sample introduction, reduce analysis time, raise the efficiency, do not need to carry out the chromatographic column switching, reduced the technical requirement to the laboratory technician, reduced production, the repacking cost of instrument.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-glass fiber, 2-column jacket column jecket, 3-inner prop column jecket, the outer column filling carrier of 4-, column filling carrier in 5-.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, novel gas component analysis chromatographic column specially in the present embodiment, comprise glass fiber 1, column jacket column jecket 2, inner prop column jecket 3, outer column filling carrier 4, interior column filling carrier 5, described interior principal post pipe 3 utilizes the decompression completion method that interior column filling carrier is inserted in inner prop column jecket 3, populated inner prop column jecket 3 and interior column filling carrier 5, put into column jacket column jecket 2 and fix, locate with the decompression completion method outer column filling carrier 4 is inserted in the column jacket column jecket, glass fiber 1 is blocked to column jacket column jecket 2 mouth of pipe places, two ends.
Utilize gas distribution principle in chromatographic column, mixed gas enters in chromatogram, and a part of gas enters in the column jacket column jecket, and another part gas enters in the inner prop column jecket, fills the retention time difference of carrier to gas, minute
By oxygen, nitrogen, carbon monoxide, methane, carbon dioxide, ethane, ethene separately, thus detect the accurate content of coal gas gas composition accurately the time.
By oxygen, nitrogen, carbon monoxide, methane, carbon dioxide, ethane, ethene separately, thus detect the accurate content of coal gas gas composition accurately the time.
Claims (4)
1. the chromatographic column that gas composition is analyzed, it is characterized in that: comprise glass fiber, the column jacket column jecket, the inner prop column jecket, outer column filling carrier, interior column filling carrier, after the inner prop column jecket is filled to interior column filling carrier, pack in the column jacket column jecket, the interior remaining space of column jacket column jecket is filled carrier and is full of, and column jacket column jecket two ends are blocked with the coloured glaze hair.
2. gas composition according to claim 1 is analyzed chromatographic column specially, and it is characterized in that: described column jacket column jecket and described inner prop column jecket are stainless steel tube, and column jacket column jecket length is 4 meters, and inner prop column jecket length is 3.8 meters.
