Abstract
The utility model discloses a quartz cracking tube used for microconstituent analysis, which is characterized in that a cracking cavity in the quartz cracking tube is divided into an inner cracking cavity and an outer cracking cavity, an inert gas inlet, an oxygen inlet and a sample inlet are located at the front end of the cracking tube and are communicated with the inner cracking cavity, the tail end of the cracking tube is provided with a backflushing oxygen inlet which is communicated with a junction of the inner cracking cavity and the outer cracking cavity, and a sample outlet which is communicated with the outer cracking cavity is arranged at the front end of the cracking tube. The quartz cracking tube is used for analyzing microconstituent of petroleum products and similar chemical products, a cracking cavity of a traditional quartz tube is divided into two cracking cavities, sample cracking time is almost doubled under the condition without increasing the lengths of a quartz tube and a cracking furnace, sample conversion rate is greatly increased, and production cost is not increased.
Description
Technical field
The utility model relates to a kind of crystalline silica cracking tube that is used for the micro constitutent analysis that is applied to industries such as petrochemical complex.
Background technology
In the constituent analysis of carrying out products such as petrochemical complex, crystalline silica cracking tube one of the critical component that is absolutely necessary.The effect of crystalline silica cracking tube is: when sample injects from the import of crystalline silica cracking tube, crystalline silica cracking tube removes import and export gas part and all places high-temperature cracking furnace, and the outlet from crystalline silica cracking tube under the promotion of carrier gas (being generally inert gas+oxygen) of the sample of injection is flowed out.At this moment, inserting pipe special after sample should obtain abundant oxicracking in the temperature range of regulation enters into the sample detection pond again and carries out quantitative measurement.
Therefore, sample is before entering the sample detection pond, and can obtain abundant pyrolysis oxidization (saying also that usually becoming is conversion ratio) in cracking process be to influence measurement result one of key factor accurately.The conversion ratio of sample is high more good more.The method that improves conversion ratio can increase the length of sample dissociation temperature and cracking tube (that is increasing the time that sample flow is crossed cracking tube) usually.Secondly, be the flow of regulating carrier gas.Yet because the requirement of constituent analysis, the flow of cracking temperature and carrier gas is normally determined, cannot at will be increased.So people can increase cracking tube length usually and reach the raising conversion ratio.If certainly will increase the length of pyrolysis furnace so again, thereby increase manufacture difficulty, strengthen production cost, and cause the bulky or the like of holistic approach instrument.
The utility model content
The purpose of this utility model provides a kind of raising sample conversion ratio, and don't increases the crystalline silica cracking tube that micro constitutent is analyzed that is used for of production cost.
The technical solution of the utility model is: be used for the crystalline silica cracking tube that micro constitutent is analyzed, comprise shell, the cracking chamber, gas feed, sample inlet and outlet, its improvements are that described cracking chamber is made of interior cracking chamber and the outer cracking chamber that is wrapped in the outside, interior cracking chamber, described gas feed is divided into inert gas import, oxygen inlet and recoil oxygen inlet, wherein inert gas import and oxygen inlet and sample inlet are positioned at the cracking tube front end, and communicate with interior cracking chamber, the recoil oxygen inlet is positioned at the cracking tube tail end, with interior, the intersection in outer cracking chamber communicates, described sample export is located at the cracking tube front end, communicates with outer cracking chamber.
Further scheme is: described inside and outside cracking chamber is coaxial; The front end of described sample inlet has sillicon rubber blocking, and is furnished with micro syringe; Described inert gas import, oxygen inlet and sample export become S shape with cracking tube front end connecting portion, the port balling-up head of sample export.
Adopt technique scheme, the utility model has become the cracking chamber of conventional quartz cracking tube into two by one, promptly interior cracking chamber and outer cracking chamber.Do not increase at the crystalline silica cracking external diameter of pipe under what the situation, almost increased by one times sample dissociation time, thereby increased the conversion ratio of sample greatly.
This utility model course of work is: sample is drawn certain sample size by micro syringe, and syringe needle is passed the interior cracking chamber that sillicon rubber blocking is injected into cracking tube.Sample flows in interior cracking chamber and carries out the cracking first time under the promotion of carrier gas (pure argon and oxygen).When this sample gas flows port to interior cracking chamber, run into after the recoil oxygen inlet is annotated into purity oxygen effect and enter the outer cracking chamber of cracking tube jointly, and then carry out secondary cracking again.And then the cracking sample gas outlet that enters cracking tube, enter the component content that detection cell carries out the quantitative measurment sample by pipe special.
According to further scheme, the utility model can further improve result of use.

Embodiment
As figure, be provided with the interior cracking chamber 6 and the outer cracking chamber 7 of coaxial cable in the shell 5 of crystalline silica cracking tube, the cracking tube front end is provided with sample inlet 1, pure argon import 2 and purity oxygen import 3 that communicates with interior cracking chamber and the sample dissociation gas that communicates with outer cracking chamber outlet 4, the cracking tube tail end is provided with the recoil purity oxygen import 8 that communicates with inside and outside cracking chamber intersection, the front end of sample inlet 1 has sillicon rubber blocking, micro syringe 9 is used to inject sample, import 2,3 with export 4 and become S shape with cracking tube front end junction, the port balling-up head of outlet 4.
