Problems solved by technology

The design of traditional light oil sulfur, chlorine and nitrogen quartz cracking tubes is unreasonable. The outlet of the vaporization chamber cannot fully combust and crack the sample with oxygen. The conversion efficiency is unstable and difficult to control. There is only one reaction chamber, and the residence time of the sample in it is short. Incomplete, resulting in low detection sensitivity of the sample, the lowest detection limit is only 0.2mg / L

Embodiment Construction

[0009] Referring to the accompanying drawings, the inlet position of the quartz cracking tube body 8 has a sample inlet 1 and a carrier gas inlet 2 that are communicated with the vaporization chamber 3, and an oxygen inlet 9 that is communicated with the first reaction chamber 10 is arranged, and the vaporization chamber outlet position is provided simultaneously. There are capillary holes 4 and a conical diffuser 5 . There is a first partition 11 with a through hole 6 between the first reaction chamber 10 and the second reaction chamber 12, and a second partition 7 with a through hole 13 between the second reaction chamber 12 and the third reaction chamber 14. The through hole 6 and the oxygen inlet 9 are located on the opposite side of the cracking tube, and the through hole 13 and the through hole 6 are also located on the opposite side. There is a ball mill joint 15 at the outlet end of the pipe body. In this embodiment, the diameter of the quartz tube in the reaction cha...

Abstract

It relates to a sulfur, chlorine and nitrogen quartz cracking tube in chemical quantitative analysis field. There are carburetor and reactor chamber inside the tube, sample entry and carrier gas intake connected with carburetor at the tube opening, oxygen intake connected with the reactor chamber that have three altogether with adjacent ones barricaded with through holes, and the opening of the carburetor having capillary holes and conical diffuser. It used for decomposition transformation of samples in chemical analysis with sufficient mixing of sample gas and the oxygen and high efficiency in decomposition, easy controllable transformation, with long idling of the samples and complete reaction, improved meter testing sensitivity, lowest testing limit reaching 0.05mg/L.

Description

technical field [0001] The invention relates to a light oil sulfur, chlorine and nitrogen quartz cracking tube, which belongs to the technical field of chemical analysis and quantitative analysis. Background technique [0002] Light oil sulfur, chlorine, nitrogen quartz cracking tube is a sample cracking device used in analyzers for determining the content of sulfur, chlorine and nitrogen elements in petroleum and chemical products by microcoulometric method, ultraviolet fluorescence method and chemiluminescence method. In petroleum and chemical products, the three elements of sulfur, chlorine and nitrogen not only cause corrosion of equipment and affect the performance stability of finished products, but also have a significant impact on the environment. Therefore, the determination of the three elements of sulfur, chlorine and nitrogen has attracted much attention. Microcoulomb method, ultraviolet fluorescence method and chemiluminescence method are the main analytical met...
