The characteristics of online analysis of sulfur content be do not receive the restriction of personal security property, real-time, analyze fast, for the regulation and control level of device provides basic data the most efficiently, so the development and application online analytical instrument is the trend of technical development from now on energetically.The used quartz burning cracking tube in laboratory is the individual layer flame tube; Because the input mode that is adopted during the on-line analysis sulfur content is different with the laboratory input mode, sample introduction directly is pressed into the burning cracking tube by gas, and the sample introduction pressure of generation is big; Jet velocity is fast; So when adopting the used common cracking tube of Laboratory Instruments to carry out on-line analysis, can make in the burning cracking tube and produce carbon deposit, the result is measured in influence.
The utility model content
For overcoming weak point of the prior art, the utility model provides a kind of quartzy burning cracking tube.This quartz burning cracking tube can satisfy the requirement of sulfur content on-line determination in gasoline, diesel oil, the gas etc., can improve the detection quality again, under the bigger situation of sample size, can effectively prevent the generation of carbon deposit.
The quartz burning cracking tube of the utility model comprises sample introduction pipe, carrier gas inlet, vapor lamp, flame tube, combustion-supporting gas inlet and escape pipe, and wherein flame tube is made up of outer tube and interior pipe; One end of outer tube is provided with escape pipe, and the other end is provided with combustion-supporting gas and replenishes inlet, and interior pipe box is contained in the outer tube; The end that one end of interior pipe and outer tube are provided with escape pipe is tightly connected, and is provided with combustion-supporting gas inlet, and the other end of interior pipe is outlet; It is inner and communicate with outer tube to be arranged on outer tube, and in vapor lamp is arranged in the pipe, an end of vapor lamp and interior pipe are provided with the end that combustion-supporting gas enters the mouth and are tightly connected; And be provided with carrier gas inlet; The vapor lamp other end is provided with opening, and communicates with interior pipe, and the sample introduction pipe stretches into vapor lamp by the carrier gas inlet end.
The length of the said vapor lamp of the utility model preferably accounts for 1/5 ~ 1/3 of interior length of tube less than interior pipe.
The outlet of pipe and the other end of outer tube left the gap in the utility model was said, were preferably 5 ~ 20mm.
The said sample introduction pipe of the utility model stretches into the length of vapor lamp according to the influence that produces the sulphur signal is regulated.
Described combustion-supporting gas is generally oxygen-containing gas, is preferably oxygen, and additional combustion-supporting gas is preferably oxygen.Described carrier gas is an inert gas, such as nitrogen, argon gas or helium.
The quartzy burning of the utility model cracking tube is applicable to online analysis of sulfur content.This cracking tube is to be made up of interior pipe and outer tube sleeve assembling structure; Replenish combustion-supporting gas at the outer tube other end; So also help sample under the prerequisite of spraying (sample introduction is concentrated relatively) sample introduction; Sulfocompound is fully burnt, be difficult for producing carbon deposit, thereby realized the on-line measurement of sulfur content in gasoline, diesel oil, the gas etc.
Description of drawings
Fig. 1 is the structural representation of the quartzy burning of the utility model cracking tube;
Embodiment
Below in conjunction with Fig. 1 the utility model is done detailed explanation.
The quartz burning cracking tube of the utility model comprises that sample introduction pipe 1, carrier gas inlet 2, vapor lamp 3, interior pipe 4, outer tube 5, combustion-supporting gas inlet 7, escape pipe 8, combustion-supporting gas replenish inlet 6, and an end of its middle external tube 5 is provided with escape pipe 8; The other end is provided with combustion-supporting gas and replenishes inlet 6, and interior pipe 4 is sleeved in the outer tube 5, and the end that an end of interior pipe 4 and outer tube 5 are provided with escape pipe 8 is tightly connected; And be provided with combustion-supporting gas inlet 6; The other end of interior pipe 4 is arranged on outer tube 5 inside for outlet and communicates with outer tube 5, and vapor lamp 3 is arranged in the interior pipe 4, and the end that an end of vapor lamp 3 and interior pipe 4 are provided with combustion-supporting gas inlet 6 is tightly connected; And be provided with carrier gas inlet 2; Vapor lamp 3 other ends are provided with opening, and communicate with interior pipe, and sample introduction pipe 1 stretches into vapor lamp 3 by carrier gas inlet 2 ends.The length of said vapor lamp 3 is managed 1/5 ~ 1/3 of 4 length less than interior pipe 4 in preferably accounting for.The outlet of pipe 4 and the other end of outer tube 5 leave the gap in said, are preferably 5 ~ 20mm.Said sample introduction pipe 1 stretches into the length of vapor lamp 3 and according to the position of sample introduction pipe the influence that produces the sulphur signal is regulated.The outlet of pipe preferably is made as opened type in said, and the sample after the gasification can fully be mixed with additional combustion-supporting gas, prevents that effectively carbon deposit from producing, and avoids the sulphuric dioxide that generates produced adsorbing, thereby avoids the testing result error.
