Description
Technical field
The utility model relates to coal gas of steel-smelting revolving furnace analyser field, relates in particular to a kind of gas analysis appearance sample gas assignment of traffic analytic system.
Background technology
The coal gas of steel-smelting revolving furnace analyser is one of visual plant of converter gas disposal system, and it is installed in the hot junction of converter flue, and environment is more abominable.The main sample gas filtrator of coal gas of converter analytical equipment pipeline system, sample gas assignment of traffic analytic system and program control system are formed.The quality of gas analysis device will directly have influence on the accuracy of gas analysis and the yield of coal gas of converter; But analytical equipment often breaks down in the use of reality; Make coal gas of converter not caused great energy dissipation and economic loss by normal recovery.Through long-term observation and analysis, we find that the sample gas assignment of traffic analytic system failure rate in the gas analysis device is very high.Because the calculating defective of its design and sampling flow cause system's cisco unity malfunction, thereby the operate as normal of impact analysis appearance influences coal-gas recovering.
Be illustrated in figure 1 as sample gas filtrator pipeline system schematic; Comprise sample gas pipe 1, process pipeline sampling by filtration device 2, secondary filter 8, first filter-paper filter 10, second filter-paper filter 11; After sample gas is filtered through first filter-paper filter 10; Carry out sample gas by sampling pump 9; And then filter back entering condensation of gas hydroextractor 12 through second filter-paper filter 11 and carry out the work of condensation hydroextractor, dried sample gas is sent into sample gas pipe 1 through secondary filter 8 by process pipeline sampling by filtration device 2.As shown in Figure 1, this sampling system also has nitrogen N
2The blowback detergent line; The nitrogen of blowback gets into blowback divider 5 through nitrogen purging main valve 6 earlier in the said nitrogen blowback detergent line; Distributed through the first nitrogen purging distribution valve, 7, the second nitrogen purging distribution valve 3 and the 3rd nitrogen purging distribution valve 4 by blowback divider 5 then, purging pressure is 10kg; So process pipeline sampling by filtration device 2, secondary filter 8 have the self-cleaning function of nitrogen blowback; And the dedusting material of first filter-paper filter 10 and second filter-paper filter 11 is a filter paper, and for smart dedusting and there is not the self-cleaning function, fundamental purpose is the analysis meter of protection sampling pump.
As shown in Figure 2; Be existing sample gas assignment of traffic analytic system synoptic diagram; Mainly magnetic oxygen analysis of pipeline, infrared analysis pipeline and the exhaust buffering pipeline by three parallel connections constitutes; Described magnetic oxygen analysis of pipeline constitutes by analyze three-way solenoid valve 21, magnetic oxygen analysis adjustable flow meter 22, magnetic oxygen analytical paper filtrator 23 and magnetic oxygen analyser 20 through pipeline magnetic oxygen in sequential series, and magnetic oxygen analyser 20 is analyzed the O in the appearance gas
2Content, working flow 0.5L/min.Described infrared analysis pipeline is by constituting through pipeline infrared analysis three-way solenoid valve 31 in sequential series, infrared analysis adjustable flow meter 32, infrared analysis filter-paper filter 33 and infrared spectrum analyser 30, and infrared spectrum analyser 30 is analyzed the CO/CO in the appearance gas
2Content, working flow 1L/min.Exhaust buffering pipeline is responsible for diffusing unnecessary gas to improve the response speed of analysis meter; Exhaust separator tube route constitutes with exhaust adjustable flow meter 41 through pipeline exhaust surge tank 40 in sequential series; Working flow is 15L/min, and total work flow of sampling pump 9 is 16.5L/min like this.
The phenomenon of the failure of existing gas analysis appearance mainly shows as because analysis of pipeline and exhaust cushion pipeline is connected after the sampling pump 9 through air inlet pipeline after parallelly connected; And analyze with flow be significantly smaller than the exhaust buffer traffic must make like this analyze very little with the aperture of flow valve, thereby when the gettering ability difference of sampling pump 9 owing to analyze with the very for a short time operate as normal that causes analysis with gas flow minimizing impact analysis instrument of the aperture of flow valve.
