2s, SO2 measure harvester.
Background technology
For any a set of Crouse's recovery technology of sulfur device, its control stress point is the volume basis ratio of adjustment of acidity gas and air, and tail gas on-line analysis regulates method to regulate air distribution higher than precision, is the important means making device be in optimum condition, therefore, tail gas H
2s/SO
2in-line analyzer is vitals for whole desulfurizer.The major function of tail gas in-line analyzer is H in Real-Time Monitoring tail gas
2s, SO
2concentration ratio, then by result feedback to claus oven, instruct the air distribution of claus oven to regulate, improve the work efficiency of Crouse desulfurizer.Claus tail gases still has certain sulphur (mainly liquid and gaseous state), and therefore, when using in-line analyzer, when sample gas enters measuring instrument, a large amount of solid-state sulphur of precipitation is directly set in desulfurizing device, blocking H
2s/SO
2the pipeline of on-line measurement instrument and sensing chamber, cause system just block within these few days and cannot run further, instrument maintainer cannot clear up again in time, directly causes analytic system in paralyzed state for a long time at the scene.Increase engineering maintenance amount and measure cost.
