Description
Technical field
The utility model belongs to environmental protection and nuclear chemical industry field, and specifically one utilizes Middle hollow fiber membrane to remove O
2, CO
2, H
2the device of O and enrichment xenon.
Background technology
In chemistry and chemical engineering process, remove the CO in air-flow
2and H
2the normally used method of O is absorption process, absorption method, freezing etc.Absorption process can pollute environment; Absorption method needs regeneration, and energy consumption is large; Deep Cooling Method also needs to consume a large amount of energy.If require the O removed in air-flow simultaneously
2and N
2, will, in conjunction with more method, cause removal of impurities equipment component very huge.
Because in surrounding air, radioxenon content is extremely low, directly cannot measure, need to adopt adsorption separation technology by after xenon enrichment, separation and purification, then carry out radioactivity survey, realize the object of radioactive xenon isotope activity concentration in monitoring of environmental air.The adsorption capacity of xenon is lower, needs adsorbent bed and the multi-stage absorption lock out operation of large-size, just can reach the concentrated requirement of xenon.
Hollow-fibre membrane is a kind of superfine hollow film pipe, and the external diameter of film pipe is about 0.25mm, and internal diameter is about 0.15mm.Polyimides has good heat endurance, mechanical strength and organic solvent-resistant ability, and maximum operation (service) temperature reaches 150 DEG C, vitrification point very high (Tg400 DEG C), is therefore the good membrane material of a class.
Theoretical according to the gap stream law (also known as law of gas diffusion) of Graham, equality of temperature is inversely proportional to the square root of pressure gap Flow Velocity and gas molar quality, Xe and O
2, CO
2and H
2the molecular weight difference of the foreign gases such as O is very large, and gap stream law is that the possibility that hollow-fibre membrane concentrates xenon provides theoretic support.
Use hollow-fibre membrane enrichment Xe and remove O
2, CO
2, H
2the Patents of the foreign gases such as O yet there are no.
Summary of the invention
The purpose of this utility model is: provide one to utilize Middle hollow fiber membrane to remove O
2, CO
2, H
2the device of O and enrichment xenon, utilizes hollow-fibre membrane (without the need to regeneration, lightweight, energy consumption is low) to carry out pretreatment to gathered gas, can effectively remove most of N
2, O
2, CO
2and H
2the impurity such as O, concentrated xenon, little in the condition of identical sample volume, size and the purifying progression of adsorbent bed can be reduced.
The technical solution of the utility model: utilize Middle hollow fiber membrane to remove O
2, CO
2, H
2the device of O and enrichment xenon, comprises air compressor machine, surge tank, and air compressor machine is connected with surge tank by PU pipe, is managed aqueous phase separation device, mass flowmenter, hollow-fibre membrane A, B, C are connected with mass flow controller successively at described surge tank rear portion by PU.Described hollow-fibre membrane A, B, C at least arrange three.Described air compressor machine is common commercially available oilless air compressor.
The beneficial effects of the utility model: utilize hollow-fibre membrane to O
2, CO
2, H
2the feature that the foreign gases such as O are different with the removal ability of Xe, can carry out pretreatment to the sample gas of large volume, while removing most of foreign gas, little to the loss of xenon, namely concentrates xenon, reduces sample volume.Utilize membrane separation technique can make sample gas volume reducing 2/3, the further enrichment being very beneficial for xenon in gas concentrates.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is main TV structure schematic diagram of the present utility model.
Detailed description of the invention
Embodiment 1, utilize Middle hollow fiber membrane remove O
2, CO
2, H
2the device of O and enrichment xenon, as shown in Figure 1, comprise air compressor machine 1, surge tank 2, air compressor machine 1 is connected with surge tank 2 by PU pipe, is managed aqueous phase separation device 3, mass flowmenter 4, hollow-fibre membrane A, B, C5,6,7 are connected with mass flow controller 8 successively at described surge tank 2 rear portion by PU.Described hollow-fibre membrane A, B, C5,6,7 at least arrange three.Described air compressor machine (1) is common commercially available oilless air compressor.
In practice, the UBE board NM-B05A Polyimide Hollow Fiber (length 60cm, external diameter 50mm) of more than three or three is connected in series with PU pipe by (1); (2) termination mass flowmenter before first hollow-fibre membrane, termination mass flow controller after the 3rd film; (3) provide source of the gas with small-sized oilless air compressor, make air successively through mass flowmenter, hollow-fibre membrane, mass flow controller; (4) flow signal of electronically module acquires film front end mass flowmenter, converses real-time traffic, then removes the mass flow controller of controlling diaphragm rear end, make gas product flow be always 1/3 of raw gas flow; (5) according to above operating procedure, can ensure that the loss late of xenon is not more than 10%, H
