Description
Technical field
The present invention relates to detector field, be specifically related to a kind of carbon molecular sieve performance high speed detector.
Background technology
In prior art, the main performance index denitrification production rate of carbon molecular sieve in pressure swing adsorption technique and product nitrogen are denseDegree all detects by small-sized pressure-swing absorption apparatus conventionally, is at carbon molecular sieve micropore at nitrogen, oxygenOn the basis of interior diffusion rate difference (the nitrogen molecular diffusion rate that oxygen molecule diameter group that diameter is less is large is fast)The nitrogen oxygen carrying out separates, and sense cycle is long, and one-time detection needs about one hour conventionally, and detection efficiency is low.
Summary of the invention
The deficiency existing for prior art, the object of the present invention is to provide a kind of simple in structure, detection weekPhase is short, the carbon molecular sieve performance high speed detector that detection efficiency is high.
For achieving the above object, the invention provides following technical scheme: a kind of carbon molecular sieve performance is examined fastSurvey device, comprise adsorption tube, the upper and lower two ends of described adsorption tube are respectively arranged with the first tube connector and the second tube connector,On described the first tube connector, be provided with the first valve, on described the second tube connector, be provided with the second valve, described inOn the second tube connector between the second valve and adsorption tube, be vertically installed with the 3rd tube connector, the described the 3rd connectsPipe connects pipe end near second and is provided with the 3rd valve, and described the 3rd valve is with respect to another of the second tube connectorVavuum pump, gas gauge, the 4th valve and oxygen analyzer are installed on the 3rd tube connector of side successively.
By adopting technique scheme, can carry out (in 5 minutes) pre-detection fast to product, screening is providedThere is the carbon molecular sieve product of certain separating power further to examine with small-sized PSA pressure-swing absorption apparatus againSurvey, poor product no longer further detects to screen out separating power, has greatly improved the detection effect of productRate.
The present invention is further set to: described vavuum pump, gas gauge, the 4th valve and oxygen analyzer respectively withThe 3rd tube connector is communicated with. By this setting, structure of the present invention is simpler, works more reliable.
The present invention is also further set to: described the first valve, the second valve, the 3rd valve and the 4th valveDoor is check valve. By this setting, the present invention is more convenient to operate, works more reliable.
The present invention is also further set to: described the first tube connector, the second tube connector seal with adsorption tube respectivelyConnect. By this setting, adsorption tube two ends connect reliable.
Advantage of the present invention is: the present invention is by check valve is set respectively on the tube connector at adsorption tube two ends,And check valve, vavuum pump, gas gauge, check valve and oxygen are installed successively on the tube connector of adsorption tube one side and are dividedAnalyse instrument, product is carried out to rapid previewing survey, can carry out (in 5 minutes) pre-detection fast to product, sieve outThe carbon molecular sieve product with certain separating power is further examined with small-sized PSA pressure-swing absorption apparatus againSurvey, poor product no longer further detects to screen out separating power, has greatly improved the detection effect of productRate.
Below in conjunction with Figure of description and specific embodiment mode, the invention will be further described.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Referring to Fig. 1, a kind of carbon molecular sieve performance high speed detector provided by the invention, comprises adsorption tube 1, instituteState adsorption tube and be respectively arranged with the first tube connector 2 and the second tube connector 3, described the first tube connector in two ends Shang Xia 1On 2, be provided with the first valve 4, on described the second tube connector 3, be provided with the second valve 5, described the second valve5 and adsorption tube 1 between the second tube connector 3 on be vertically installed with the 3rd tube connector 6, described the 3rd tube connector6 are provided with the 3rd valve 7 near the second tube connector 3 ends, and described the 3rd valve 7 is with respect to the second tube connector 3The 3rd tube connector 6 of opposite side on vavuum pump 8, gas gauge 9, the 4th valve 10 and oxygen are installed successivelyAnalyzer 11.
For making work of the present invention more reliable, as preferably, vavuum pump 8 described in the present embodiment, gas gauge 9,The 4th valve 10 and oxygen analyzer 11 are communicated with the 3rd tube connector 6 respectively.
Described the first valve 4, the second valve 5, the 3rd valve 7 and the 4th valve 10 are check valve.Described the first tube connector 2, the second tube connector 3 are tightly connected with adsorption tube 1 respectively.
The present embodiment passes into air the adsorption tube 1 of filling carbon molecular sieve, after adsorbing separation completes, measures absorptionManage volume and the oxygen concentration of 1 interior mist, because the diffusion rate of oxygen in carbon molecular sieve micropore is greater thanNitrogen, the micropore of carbon molecular sieve can preferential adsorption of oxygen, and therefore the oxygen concentration of last mist compares airOxygen concentration want high. The volume of mist is subject to the impact in the aperture of carbon molecular sieve micropore, and aperture is persorption greatlyThe volume that closes gas is large, and the volume of the little mist in aperture is little.
When practical application, carbon molecular sieve is filled to adsorption tube 1, the first valve 4 and the second valve 5 is opened; TheUnder the state of three valve closings, pass into 25 DEG C of air 1min(room temperatures, an atmospheric pressure); By the first valve4, the second valve 5 and the 4th valve 10 are closed, and the 3rd valve 7 is opened, by vavuum pump 8 by adsorption tubeAfter gas in 1 is discharged, then be pressed into gas gauge 9, measure gas volume; Then the 4th valve 10 is opened,Gaseous mixture in gas gauge 9 is passed into oxygen analyzer 11, detect the oxygen concentration of mist.
Above-described embodiment, to specific descriptions of the present invention, is only used to further illustrate the present invention, can notBe interpreted as limiting the scope of the present invention, the technician of this area is according to the content pair of foregoing inventionThe present invention make some nonessential improvement and adjust all fall into protection scope of the present invention within.
