Description
Technical field
This utility model relates to the sample introduction gas handling system of online electrochemical oxygen analyser.
Background technology
Requiring oxygen-free environment in the stove of heat-treatment furnace, the oxygen content therefore measuring furnace atmosphere is most important.Online electrochemistry oxygen analyser is by the sample gas suction oxygen converter in stove, by analyzing the oxygen content in sample gas, determines the numerical value of oxygen content in stove.According to these data, operator decides whether to increase in stove the amount being passed through nitrogen, prevents increasing of oxygen content in stove.It is said that in general, the moisture carried in sample gas, not only can cause the deviation of measurement, also can damage oxygen cell, reduce its service life.
The sample gas processing system of existing oxygen analyzer, sees Fig. 1, including ball valve 1, air pump 2, filter 3 and oxygen sensor.Air pump 2 works, and sample gas enters to filter 3 by ball valve 1, filters out dust impurity, is connected with oxygen sensor.Owing to can not dispose the moisture in sample gas, oxygen cell after used a period of time, can be stained with and pay a large amount of water droplets, cause oxygen cell to damage；The measured deviation that moisture causes simultaneously, reduces the accuracy of operator's operation；In order to reduce the moisture in sample gas as far as possible, putting stove after taking each blowing out again, thus need just can come into operation oxygen analyzer after baker a period of time, and owing to there is no the data of oxygen content in stove in this section of furnace drying time, can not produce, thus cause the waste of combustion gas.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of gas analyzer for O2 sample gas processing system for above-mentioned prior art; realizing on the existing function basis of existing oxygen analyzer sample gas processing system; the moisture in sample gas can also be removed; improve the accurate reliability of analytical data, and contribute to protecting oxygen cell.
The technical scheme in the invention for solving the above technical problem is: the sample gas processing system of a kind of gas analyzer for O2, including ball valve, exsiccator, air pump, electronic dehumidifying device, filter and oxygen sensor, the outlet side of described ball valve is connected with the import of exsiccator, the outlet of described exsiccator is connected with the import of air pump, described delivery side of pump of bleeding is connected with the import of electronic dehumidifying device, the described outlet of electronic dehumidifying device is connected with the import of filter, and the outlet of described filter is connected with oxygen sensor.
Preferably, described exsiccator is double glazing pipe, and described double glazing pipe is internal fills molecular sieve.
Preferably, described electronic dehumidifying device lower end is provided with leakage fluid dram, and described leakage fluid dram is connected with apparatus for recovering.
Compared with prior art, the utility model has the advantage of: by accessing exsiccator in sample gas processing system, the most moisture in sample gas are removed；On this basis, after air pump, access electronic dehumidifying device again, the moisture of small part will be remained and may remove from the fraction moisture that air pump enters.Have
1) extending the service life of oxygen cell, the use time adds one times；
2) eliminate the measured deviation caused due to moisture, improve the accuracy of operation；
3) greatly reduce oxygen analyzer to come into operation required furnace drying time, decrease the waste of combustion gas.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sample gas processing system of existing oxygen analyzer；
Fig. 2 is the structural representation of the sample gas processing system of oxygen analyzer in this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As in figure 2 it is shown, the gas analyzer for O2 sample gas processing system in the present embodiment, including ball valve 1, exsiccator 5, air pump 2, electronic dehumidifying device 6, filter 3 and oxygen sensor 4.In stove, sample gas is connected with ball valve 1, the outlet side of described ball valve 1 is connected with the import of exsiccator 5, the outlet of described exsiccator 5 is connected with the import of air pump 2, the outlet of described air pump 2 is connected with the import of electronic dehumidifying device 6, the outlet of described electronic dehumidifying device 6 is connected with the import of filter 3, and the outlet of described filter 3 is connected with oxygen sensor 4.Described exsiccator 5 is double glazing pipe, and described double glazing pipe is internal adds molecular sieve.Described electronic dehumidifying device 6 lower end is provided with leakage fluid dram, and described leakage fluid dram is connected with apparatus for recovering (not shown).
The operating type of the present embodiment sample gas processing system is, opens air pump 2, and sample gas enters exsiccator 5 by ball valve 1, and the most moisture in sample gas are removed by exsiccator 5 by molecular sieve；From exsiccator 5, sample gas out enters to electronic dehumidifying device 6, will remain the moisture of small part and may completely remove from the fraction moisture that air pump 2 enters in sample gas.The sample gas processed through the sample gas processing system of the present embodiment enters oxygen converter, for more existing processing system, possesses advantages below: extend the service life of oxygen cell, adds one times；Eliminate the measured deviation caused due to moisture, improve the accuracy of operator's operation；Greatly reduce oxygen analyzer to come into operation required furnace drying time, decrease the waste of combustion gas.
After transformation, the oxygen cell replacement cycle of oxygen analyzer 2 wheat harvesting periods before transformation, rise to the time of 6 months.Put into production again after heat-treatment furnace shutdown maintenance, when furnace temperature reaches production requirement, owing to oxygen analyzer can come into operation and feedback data in time, be therefore no longer necessary to carry out baker, thus greatly reduce the waste of combustion gas.
In addition to the implementation, this utility model also includes the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, within all should falling into this utility model scope of the claims.
