Description
Technical field
The utility model relates to sampling probe, particularly a kind of sampling probe that is applied in the measurement of sulphur ratio.
Background technology
In industrial processes, can produce or use a lot of gases, above-mentioned gas is carried out on-line analysis for realizing that production technology optimization, security control or environment protection emission control are most important.For example in Crouse's recovery technology of sulfur, reach optimum efficiency, need the mol ratio of interior sulfuretted hydrogen of measuring channel and sulfur dioxide gas, and measurement feedback is arrived DCS in order to make sulphur recovery, thus the control air inflow, and making described mol ratio is 2:1.
Usually use hot method to measure sulphur ratio, mode as the employing of Brimstone company, as shown in Figure 1, use the sulfurous gas in the probe 52 sampling tested pipelines 51, after lead to the sulfur vapor that complicated pretreatment device 53 is removed wherein through long gas line, feed then in the measuring chamber 54 and measure, photoelectric device is installed in the both sides of measuring chamber 54.Ejector 6 is installed in the downstream of measuring chamber 54 by described system, thereby extracts the sulfurous gas in the tested pipeline 51 out.Described ejector 6 comprises suction gas passage 61, sprays the gas passage 63 and the passage 62 of going into to emanate, and the described passage 62 of going into to emanate is collinear with injection gas passage 63, is 90 ° and suck gas passage 61 with the angle that sprays gas passage 63.In order to reduce the danger that gas circuit condensation sulphur stops up, also need the parts in the gas circuit (comprise gas line, pretreatment system, measuring chamber, ejector etc., also comprise zeroing and demarcation gas line in the system) are heated to higher temperature, as 150 ℃.
Technique scheme mainly has following deficiency:
1, utilize separated components to realize the sampling, pipeline transmission, sulfur vapor filtration, concentration analysis of sulfurous gas, flow back to pipeline at last, and adopt omnidistance companion's heat, complex structure, reliability is low.
2, the suction gas passage of ejector is 90 ° with the angle that sprays the gas passage, and sulphur residual in the gas easily stops up ejector, causes system normally to sample.
3, the gas in the tested pipeline will could feed measuring chamber through long gas pipeline, and response speed is low.
4, cost height, many parts have improved production cost; In order to use ejector, also to be equipped with special high-pressure air source, improved use cost.
5, engineering maintenance amount is big, needs the described filtrator of periodic maintenance: pull down filtrator and cleaning, install process complexity, length consuming time afterwards again.
In order to solve complex structure in the technique scheme, deficiency that response speed is low, application number is that 200710068291.8 Chinese patent has disclosed a kind of formula sulphur ratio instrument on the throne, as shown in Figure 2.Described ratio instrument comprises measuring head and is attached thereto the sampling pipe 11 that connects, and is provided with measuring chamber 18 in the measuring head, and draft tube 13 and escape pipe 14 are set in the sampling pipe.Measuring chamber 18 connects draft tube and escape pipes, connects on the passage of measuring chamber and escape pipe fluidic device is installed: the passage 15 of going into to emanate of described fluidic device is an acute angle with the angle that sucks 16 in gas passage, sucks gas passage 16 and goes out to emanate passage 17 conllinear.
Above-mentioned fluidic device pumps to the sulfurous gas in the pipeline in the measuring chamber 18, sends back in the pipeline more afterwards.Described fluidic device has just slowed down the assembly of sulphur in the pipeline to a certain extent, and the described continuous type time of ratio instrument can be above 10 days yet; Have, the high-pressure induct gas that uses in the fluidic device has improved operating cost again.
