It just can guarantee that the good operation of equipment.
Publication number CN206146829U patent is connected by two side tracheaes of installation with air guide channel so that high frequency is red
Outer carbon and sulfur analytical instrument can screen density simultaneously with the impure gas that flow velocity is not consistent when gas is flowed into inside air guide channel
And air guide channel is discharged from side tracheae, so as to enhance the constant current stability of the device.
Publication number CN205720149U patent discloses a kind of computer carbon and sulfur analytical instrument for applying iodine liquid bottle, and its is main
The improvement that sulfurous gas absorbs in iodimetric titration of burning.
It is to titanium dioxide by fluorescence photometer that publication number CN205484057U patent, which discloses a kind of flue gas analyser,
Sulphur gas is detected.
The content of the invention
Goal of the invention：It is raw in chemical production field because sulphur is often catalyst poisoning or a key factor of failure
Production raw material and catalyst in sulfur content number frequently encountered in assay laboratory.And chromatography of ions is real in general chemical analysis
Room is tested all to be widely used.After the utility model absorbs the sulphur in material by gas absorbing device, chromatography of ions is utilized
Carry out analysis of sulfur content.
Technical scheme：The device of analysis of sulfur content is carried out for being absorbed by gas, it is characterised in that described device includes
Oxygen cylinder, Drexel bottle, high-temperature tubular heating furnace, gas absorption bottle, each part are sequentially connected by pipeline；The Drexel bottle includes
Pickling bottle, drying bottle, demisting bottle；The gas absorption bottle includes bottle, sample feeding pipe, bubbler, outlet piston, and sample feeding pipe is horizontal
Section and the side wall of bottle are worn and connect, and vertical section stretches in bottle lower end；Bubbler is connected to sample feeding pipe lower end, has on bubbler and uniformly divides
The passage of cloth, bottle lower end are provided with outlet piston.
Usually, the high-temperature tubular heating furnace can indicate temperature in real time, and maximum temperature control range is 1200-1300
℃。
The gas absorption bottle is two.
The gas absorption bottle bottle is fabricated by glass or ceramics.
The utility model is after making test substance by being burnt in tubular type high temperature combustion furnace, to be connected and absorbed by flexible pipe
Bottle entrance, and the air or oxygen stream anticipated is brought bubbling in the gas absorption bottle for fill hydrogen peroxide absorbing liquid into and inhaled
Receive, the piston outlet that the gas not being completely absorbed is equipped with by first absorption bottle upper end, second is connected to by flexible pipe
Bubble absorption, gas heat the absorbing liquid released from absorption bottle to individual absorption bottle after absorption after a while again, break
Unnecessary hydrogen peroxide is gone bad, now sulphur is present in liquid in the form of sulfate radical, is passed through chromatography of ions and is carried out determining for sulfate radical
Amount analysis, obtains sulfur content in analyte.
The hydrogen peroxide absorbing liquid after dilution of certain volume is housed in the usual gas absorption bottle.
The utility model also includes the piston and connecting line known to the field.
The course of work of the present utility model is as follows：The peroxidating after dilution of certain volume is housed first in absorption bottle
Hydrogen absorbing liquid, oxygen cylinder valve or drawdown pump are opened, adjust flow, the bubbler of absorption bottle is discharged uniform bubble, sample
The tubular heater being sent into by combustion boat under certain temperature.Through absorption after a while, it is ensured that the sulphur of sample is aoxidized with sulphur
The form of thing is fully absorbed by the liquid of absorption bottle.The outlet piston of absorption bottle is opened, absorbing liquid is flowed into beaker.Heating is burnt
Liquid in cup, unnecessary hydrogen peroxide is destroyed, and concentrated liquid uses chromatography of ions to certain volume, cooling constant volume in volumetric flask
Sulfate radical content in analytical solution.
The utility model mentality of designing is that the instrumentation of sulphur is surveyed without being equipped with, simply by special absorption plant, then
The ion chromatograph being all equipped with mostly using chemical laboratory is further analyzed.Step is easy, caused by human factor
Error is seldom, ease of use human users.
