Abstract
The invention relates to the field of detecting instruments, in particular to an air purifying device for a gas chromatograph. A water discharger can make surplus air supplied to a workshop by an air compression station obtain full standing and water discharge, then the air enters a large-capacity dryer for complete purification and finally enters a miniature purifier for purification, it is ensured that completely-purified qualified air is supplied to a gas chromatograph body for usage, and the accuracy of sample content detected by the gas chromatograph body is ensured. Allochroic silica gel is arranged in the dryer, and when the allochroic silica gel becomes red, a worker is reminded to perform replacement again, and the working quality of a drying pipe can be effectively ensured. Glass wool is arranged at two ends of the allochroic silica gel in the drying pipe, silica gel particles are prevented from blocking an air channel, the stability of the air channel is improved, the failure rate is reduced, and a drying effect is better. An air inlet of the water discharger is provides with an air inlet pressure reducing valve so that residual air can enter the water discharger after being subjected to pressure reduction, and an air outlet is provided with an air outlet pressure reducing valve to ensure that the residual air in the dryer is not over-pressured.
Description

Background technology
Red, orange, green, blue, yellow (ROGBY) is a kind of point of analysis of variance method, in analytical chemistry, organic chemistry, life
The fields such as thing chemistry have a very wide range of applications, and wherein, flow according to during chromatography
Mutually with fixing this biphase state mutually, red, orange, green, blue, yellow (ROGBY) is divided into gas chromatography, liquid chromatograph
Method, gas-solid chromatography, gas-liquid chromatography, liquid-solid chromatography(LSC) and liquid-liquid cromatography, wherein, right
During Composition Analysis of Natural Gas, general employing gas chromatography is analyzed, the analytical tool of use
For gas chromatograph.
Must there is the carrier gas of certain flow when the chromatographic column of gas chromatograph normally works, need to use
Special-purpose air generator, and special-purpose air generator needs to produce extra power consumption and maintenance cost,
So can produce huge cost, in order to cost-effective, workshop institute will be supplied from air compression station
Additional air, supply gas chromatograph uses, but air moisture content is very big, can shadow
Ring the content of gas chromatograph detection sample, cause that many strange peak, Za Feng occur, even do not go out
Peak makes hydrogen flame detector self-extinguishing.
Summary of the invention
The deficiency existed for prior art, the present invention provides a kind of cost-effective and ensures detection
Sample size gas chromatograph accurately.

Compared with prior art, the invention has the beneficial effects as follows:
1, the water trap of the present invention can make to obtain sufficient standing from workshop leaked-in air residual air
Enter back into after draining after the big exsiccator of capacity is fully cleaned up and finally enter miniature purification utensil,
Ensure that the acceptable air supply chromatograph body being fully cleaned up uses, it is ensured that this health check-up of chromatograph
Survey the accuracy of sample size；
2, it is provided with variable color silica gel in the exsiccator of the present invention, when variable color silica gel reddens, carries
Awake staff needs again to change, and the work quality of drying tube can be effectively ensured；In drying tube
The two ends of variable color silica gel are provided with glass cotton, it is to avoid silica gel particle blocks gas circuit, improve gas
The stability on road, reduces fault rate, beneficially life-time service, and drying effect is more preferable；
3, the air inlet of water trap of the present invention is provided with air inlet air relief valve so that air residual air
Entering water trap after decompression, gas outlet is provided with gas outlet air relief valve, it is ensured that enters and is dried
Air residual air not superpressure in device.

Body.
Detailed description of the invention
A kind of air cleaner for gas chromatograph as shown in Figure 1, including miniature only
Changing device 3, the other end of miniature depurator 3 connects one end of exsiccator 2, exsiccator 2 another
One end connects water trap 1, is uniformly filled with variable color silica gel 21, drying tube 2 in exsiccator 2
The two ends of interior variable color silica gel 21 are provided with glass cotton 22.
As in figure 2 it is shown, the other end of miniature depurator 3 connects the air inlet of chromatograph body 4.
Further, the air inlet of water trap 1 is provided with air inlet air relief valve 11, water trap 1
Gas outlet be provided with gas outlet air relief valve 12, the bottom of water trap 1 is provided with drain valve 13.
Specific works flow process is: from the air residual air pressure one used by air compression station supply workshop
As be 0.6MPa, can be carried out by air inlet air relief valve before pipeline is inputted into water trap
Decompression so that the air residual air pressure entering water trap is less than 0.4MPa, then through gas outlet
After air bleeding valve decompression, pressure is less than 0.1MPa, it is ensured that enter the air in exsiccator will not superpressure,
The bottom of water trap is provided with drain valve, is opened by the drain valve of water trap every day after end-of-job
Carrying out draining, it is ensured that the work quality of water trap, dryer capacity is big, can be by air residual air
Be completely dried laggard enter miniature purification utensil, it is ensured that supply chromatograph body use air more than
