Abstract
The present invention discloses a quartz tube special for detecting sulfur by impulse type ultraviolet fluorescence method. Sampling tube and sample discharging tube are set respectively on two end of firebox, a diameter accrescent vaporizing cavity is on the end of the sampling tube inserted in the firebox, a buffer tube with one end closed and one end opened is in the firebox, the sample discharging tube extends into the buffer tube and the inside and outside of the buffer tube have clearance, and the exit of said vaporizing cavity is taper ring channel. Because the present invention employs new structure design, it's convenient for sampling in a large, prolonging the circulation time of the sample in the firebox and making the sample burning sufficiently, eliminating remnant carbon and avoiding the quartz tube and correlation gas roads changing black, improving the sulfur detecting efficient. The sulfur detecting lower limit is 10PPb in impulse type ultraviolet method.
Description
Technical field
The present invention relates to a kind of flame tube that ultraviolet fluorescence method is measured sulfur content that is used for, particularly be exclusively used in the quartz ampoule of pulse type ultraluminescence method sulphur.
Background technology
In petrochemical complex production and field of environment protection, accurately sulfur content is most important in the working sample.Generally adopt ultraviolet fluorescence method to survey sulphur at present, at first sample will be sent in the flame tube during operation, in excess oxygen, make sulphur be oxidized to sulphuric dioxide.By industry standard (SH/T0689-2000) requirement, existing flame tube has two types of direct injected flame tube and boat sample introduction flame tubes, its primary structure is that the middle part is a burning chamber, two ends have the sample introduction pipe respectively and go out the sample pipe, and the position of sample introduction pipe insertion burning chamber is the constant straight pipe of caliber, and there is following shortcoming in this structure: the sample feeding amount is little, sample is short at the burning intraductal retention time, can not fully burn, the carbon residue of generation causes flame tube and relevant gas circuit blackout, and the sulphur precision is surveyed in influence.Therefore, existing flame tube can not adapt to the needs of more advanced pulse type ultraluminescence method sulphur.
Summary of the invention
The technical problem to be solved in the present invention is the weak point that overcomes existing flame tube, and a kind of sample size that can increase sample is provided, and prolongs the cycling time of sample in burning chamber, thereby improves the pulse type ultraluminescence method sulphur of surveying the sulphur effect.
Technical scheme of the present invention is: the pulse type ultraluminescence method sulphur middle part is a burning chamber, the burning chamber two ends have the sample introduction pipe respectively and go out the sample pipe, improvements are that a end that described sample introduction pipe inserts burning chamber is provided with internal diameter size obviously greater than the vaporization chamber of sample introduction bore, described burning chamber is provided with separator tube with the burning chamber coaxial cable near the position that goes out the sample pipe, this separator tube is towards the end sealing of sample introduction pipe, other end opening, describedly go out the sample pipe and extend in the separator tube, and in the separator tube, outer wall with go out sample pipe outer wall, all gapped between the burning chamber inwall.
Further scheme is: the outlet of described vaporization chamber is the tapered annular passage.
Adopt above technical scheme, the sample introduction pipe insertion end of this quartz ampoule is provided with vaporization chamber, is convenient to a large amount of sample introductions, sample size reaches 250 μ L, and the vaporization chamber outlet is horn-like, and there is a taper block centre, form the tapered annular passage, help the diffusion of sample and the mixing of gas; Be provided with separator tube in the burning chamber of quartz ampoule, increased the combination gas passage that flows, prolonged the cycling time of sample in burning chamber, guarantee sufficient combustion, eliminate carbon residue, can not make quartz ampoule and relevant gas circuit blackout, effectively improve and survey the sulphur effect.Use this quartz ampoule, cooperate pulsed fluorescence ultraviolet method to measure trace total sulfur by using, be limited to 10PPb under the survey sulphur that obtains, than the present survey sulphur lower limit (100PPb～200PPb) be significantly increased that can reach.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Referring to accompanying drawing, pulse type ultraluminescence method sulphur is fired meticulously by high grade quartz glass and is formed, and anti-burning temperature reaches more than 1500 ℃, and cavity volume is greater than existing flame tube.This quartz ampoule middle part is a burning chamber 4, the burning chamber two ends have sample introduction pipe 1 respectively and go out sample pipe 6, and oxygen and carrier gas air intake opening arranged, the end that the sample introduction pipe inserts burning chamber is provided with the vaporization chamber 2 that internal diameter obviously increases, be provided with separator tube 5 with the burning chamber coaxial cable near the position that goes out the sample pipe in the burning chamber, this separator tube is towards the end sealing of sample introduction pipe, other end opening, above-mentionedly go out the sample pipe and extend in the separator tube, and in the separator tube, outer wall with go out sample pipe outer wall, all gapped between the burning chamber inwall, the outlet position of above-mentioned vaporization chamber is horn-like, and there is a taper block 3 centre, forms a circle tapered annular passage.
Claims (2)
1, a kind of pulse type ultraluminescence method sulphur, the middle part is a burning chamber, the burning chamber two ends have the sample introduction pipe respectively and go out the sample pipe, it is characterized in that a end that described sample introduction pipe inserts burning chamber is provided with internal diameter size obviously greater than the vaporization chamber of sample introduction bore, described burning chamber is provided with separator tube with the burning chamber coaxial cable near the position that goes out the sample pipe, this separator tube is towards the end sealing of sample introduction pipe, other end opening, describedly go out the sample pipe and extend in the separator tube, and the inside and outside wall of separator tube and go out between sample pipe outer wall, the burning chamber inwall all gapped.
2, by the described pulse type ultraluminescence method sulphur of claim 1, it is characterized in that: the outlet of described vaporization chamber is the tapered annular passage.
