Abstract
The invention belongs to the field of purification for inert gases and especially relates to an online purification method for inert gases based on titanium metallic chemical properties. The online purification method is characterized in that the difference of the chemical properties of metal titanium under high temperature and low temperature states is utilized to purify the inert gases, and meanwhile, the problem of possibility of introducing active materials of the conventional purification method for inert gases can be avoided.
Description
Technical field
The invention belongs to inert gas purge field, more particularly to a kind of noble gases based on titanium chemical property exist
Line purification method.
Background technology
During the spectrum experiment for carrying out laboratory level, it is often desirable to using highly purified noble gases.But by
The maximum vacuum that can be reached in current gas circulation line is about 10-12Pa magnitudes, what is remained in gas circulation line are micro
Oxygen, nitrogen isoreactivity molecule will severely impact the result of spectrum experiment in experimentation, and this is cannot be by selecting high-purity
What noble gases were improved.If the common purification method used in experimental system (for example using Zn-Al pumps, Cu CuO
Deng), will inevitably lead to test the introducing of other active substances such as Zn, Al, Cu in pipeline again, affect the result of experiment.
To overcome above contradiction, the present invention to propose a kind of method of laboratory high-purity noble gases in-line purification, both can be to inertia
Gas carries out in-line purification, can avoid the introducing of the active substance in purification process again, achieved with good in spectrum experiment
Actual effect.
The content of the invention
In order to overcome high-purity noble gases in-line purification in laboratory system to be introduced into active substance in purification process
The contradiction of experiment pipeline, the present invention provide a kind of method of laboratory high-purity noble gases in-line purification.The method can not only
The enough oxygen removed in experiment pipeline, nitrogen isoreactivity molecule, also can avoid the introducing of other active substances in purification process simultaneously.
The content of this method is：Due to titanium, chemical property is highly stable at room temperature, and titanium at high temperature
Chemical property is very active, and which generates covalent bond and ion key compound with halogen and oxygen group elements reaction；With transition elements,
Hydrogen, beryllium, boron family, carbon family and nitrogen group element generate metallic bond compound and limit solid solution；With zirconium, hafnium, vanadium family, chromium race, scandium element
Generate unlimited solid solution；Especially when heating more than 650 DEG C, titanium and oxygen kickback, and when more than 700 DEG C, then with
Also there is kickback in nitrogen.Even but noble gases are not also reacted with titanium at high temperature.
High temperature titanium sponge cleaning system is by rustless steel cylinder, titanium sponge, heater, temperature controller and gas piping composition.Knot
Structure is very simple.
In use, high temperature titanium sponge cleaning system is concatenated in gas circulation line.Noble gases are in gas circulator
In the presence of flow through high temperature titanium sponge cleaning system, remove the impurity such as deoxygenation, nitrogen.
After the purge is complete, if only carrying out experiment using pure inert gas, high temperature titanium sponge cleaning system can be kept
Operation, the purity of noble gases is kept during whole experiment.
Carry out experiment if necessary to the mixture using noble gases with other gases, then can close net with high temperature titanium sponge
Change the pipeline of device connection, open the gas circulation branch road in parallel with high temperature titanium sponge cleaning system, now can be in gas cyclic system
The material needed for the experiment such as halogen is added in system, is used after mixing with noble gases in the presence of gas circulator.Due to
Hardly there is chemical reaction in normal temperature state in titanium, therefore it is non-to be introduced into the micro room temperature titanium of experiment pipeline with any material
It is often stable, do not interfere with the result of experiment.
The present invention has advantages below：
1st, can remove oxygen in gas circulation line after evacuation contained by remaining and experiment noble gases itself,
Nitrogen isoreactivity molecule.
2nd, as room temperature titanium is highly stable, can avoid introducing due to the active substance caused by noble gases in-line purification.
3rd, the method is simple to operate, with low cost.
