Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Referring to Fig. 1, a kind of carbonaceous molecular sieve performance high speed detector that the utility model provides, comprise adsorption tube 1, described adsorption tube is respectively arranged with first connecting pipe 2 and second connecting pipe 3 in two ends about in the of 1, described first connecting pipe 2 is provided with first valve 4, described second connecting pipe 3 is provided with second valve 5, be vertically installed with the 3rd connecting pipe 6 on second connecting pipe 3 between described second valve 5 and the adsorption tube 1, described the 3rd connecting pipe 6 is provided with the 3rd valve 7 near second connecting pipe, 3 ends, on the 3rd connecting pipe 6 of described the 3rd valve 7 with respect to the opposite side of second connecting pipe 3 vacuum pump 8 is installed successively, gasometer 9, the 4th valve 10 and oxygen analyzer 11.
For making the utility model work more reliable, as preferably, the described vacuum pump 8 of present embodiment, gasometer 9, the 4th valve 10 and oxygen analyzer 11 are communicated with the 3rd connecting pipe 6 respectively.
Described first valve 4, second valve 5, the 3rd valve 7 and the 4th valve 10 are retaining valve.Described first connecting pipe 2, second connecting pipe 3 are tightly connected with adsorption tube 1 respectively.
Present embodiment feeds air the adsorption tube 1 of filling carbonaceous molecular sieve, after adsorptive separation is finished, measure volume and the oxygen concentration of mixed gas in the adsorption tube 1, because the rate of diffusion of oxygen in the carbonaceous molecular sieve micropore is greater than nitrogen, the micropore meeting preferential adsorption oxygen of carbonaceous molecular sieve, therefore the oxygen concentration of last mixed gas is than oxygen concentration of air height.The volume of mixed gas is subjected to the influence in the aperture of carbonaceous molecular sieve micropore, the aperture greatly then persorption to close the volume of gas big, the volume of the little mixed gas in aperture is little.
During practical application, carbonaceous molecular sieve is filled adsorption tube 1, the first valve 4 and second valve 5 is opened; Under the state of the 3rd valve closing, 25 ℃, one atmospheric pressure of bubbling air 1min(room temperature); First valve 4, second valve 5 and the 4th valve 10 are closed, and the 3rd valve 7 is opened, and after by vacuum pump 8 gas in the adsorption tube 1 being discharged, is pressed into gasometer 9 again, measures gas volume; The 4th valve 10 is opened then, and the combination gas in the gasometer 9 is fed oxygen analyzer 11, detects the oxygen concentration of mixed gas.
Above-described embodiment is to specific descriptions of the present utility model; only be used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection domain, the technician of this area makes some nonessential improvement and adjusts the utility model according to the content of above-mentioned utility model and all falls within the protection domain of the present utility model.
