Abstract
Existing CO2 gas refrigerations purifying process, precisely temperature control, purity it can not be difficult to reach requirement by liquid nitrogen frozen.The utility model proposes a kind of CO2 gas refrigerations device, using sterlin refrigerator as low-temperature receiver, can in 10 minutes fast cooling to less than 100 DEG C, and accurate temperature control can be needed according to user, other miscellaneous gas are removed by CO2 gas refrigerations and by vacuumizing mode, while the CO2 gases purified, eliminate liquid nitrogen using, facilitate user.
Description
Technical field
The present invention relates to a kind of CO2 gas refrigerations device, after the CO2 freezings in mixed gas, passes through the side vacuumized
Formula removes the gas that cleans, and obtains high-purity CO2 gases.
Background technology
, it is necessary to be analyzed by reacting acquisition CO2 gases with water in some commercial Applications such as isotope production technology, but
Other miscellaneous gas can be also produced during being, at this stage, go method of the gas generally by liquid nitrogen frozen that clean, gas container is whole
Body is immersed in liquid nitrogen, and CO2 therein is frozen into frost and is attached to container inner wall face, is vacuumized except after impurity elimination gas, liquid nitrogen
Cup is taken away, and CO2 is gasified, you can to obtain purer CO2 gases.In theory, above-mentioned CO2 purification for gas scheme is feasible,
But practical application is not but highly desirable, two problems are primarily present：First, the accurate temperature control of liquid nitrogen can not be realized.Liquid nitrogen temperature exists
Near 77 ° of K (- 196 DEG C), its cold is very big, it is difficult to accurate temperature control, therefore, while CO2 gases are frozen, also has in miscellaneous gas
The gas of other compositions is frozen, and can not be efficiently separated removal, be obtained high-purity co2 gas.Second, in industrial practical application,
The purchase of liquid nitrogen from far-off regions and transport are by a definite limitation, in a small amount of, multiple batches of campaign, if live liquid nitrogen is disappeared
Consumption finishes, and obtains the new liquid nitrogen time and does not know, and the risk that experiment can not efficiently accomplish be present.
The content of the invention
In order to solve in above-mentioned commercial Application, precisely temperature control, purity requirement can be reached in CO2 gas refrigeration techniques
Problem, the utility model proposes a kind of CO2 gas refrigeration devices based on sterlin refrigerator, not only can precisely temperature control it is effective
Freezing CO2 gases, the gas that cleans is removed, and eliminate liquid nitrogen use, while facilitating user, provided for campaign reliable cold
Source.
Realize that the technical solution of the utility model is as follows：
A kind of CO2 gas refrigerations device mainly includes：Special sterlin refrigerator, low temperature cold chamber, gas sample tube, Chu Leng
Pipe, heat screen, heat-insulating material, Special purpose temperature controller.The temperature of CO2 gas refrigerations needs is under normal pressure：- 78.5 DEG C, special this
Special woods refrigeration machine can in 10 minutes fast cooling to less than -100 DEG C, and can according to the accurate temperature control of user's needs, by low temperature cold
Chamber and gas sample tube cool and are maintained at -80 DEG C or so, meet CO2 gas refrigeration needs, due under this warm area, during
Other miscellaneous gas remain in that gaseous state, are easy to remove by vacuumizing mode.
The beneficial effect of the utility model is to freeze CO2 gases by accurate temperature control, effectively remove the gas that cleans, and exempt
Liquid nitrogen use, for campaign provides reliable low-temperature receiver.
Brief description of the drawings
Fig. 1 is a kind of CO2 gas refrigerations apparatus structure schematic diagram involved in the present invention；
In figure：1st, special sterlin refrigerator 2, Chu Leng pipes 3, low temperature cold chamber 4, gas sample tube 5, heat screen 6,
Heat-insulating material 7, Special purpose temperature controller.
Embodiment
As shown in figure 1, low temperature cold chamber（3）It is placed in special sterlin refrigerator（1）Chu Lengguan（2）On, gas sample
Pipe（4）It is built in low temperature cold chamber, heat screen（5）By Chu Lengguan（2）, low temperature cold chamber（3）Be enclosed in its inner chamber, and with foaming
The heat-insulating materials such as agent（6）Filling insulation, gas sample tube（4）One end is from heat screen（5）Center is stretched out.This refrigerating plant works
When, pass through Special purpose temperature controller（7）It can start, control special sterlin refrigerator（1）, quickly by low temperature cold chamber（3）Taken with gas
Sample pipe（4）Cool and be maintained at -80 DEG C or so, by CO2 gas refrigerations in gas sample tube（4）On inwall.
Gas sample tube（4）Heat screen part is stretched out, can be connected with vacuum system pipeline, opening vacuum system can extract
The gas that cleans is removed, vacuum system is closed afterwards, special sterlin refrigerator（1）It is stopped, after the gasification of CO2 solid sublimations, you can
Obtain the high-purity CO2 gases needed.
