气肋型弥散富氧充气帐篷的研制及性能测试
Development and experimental test of ribbed, oxygen-enriched and inflatable tent
摘要
Abstract
Objective To develop a ribbed,oxygen-enriched and inflatable tent to fulfill the requirements for mobile enriched oxygen supply under plateau conditions.Methods The tent was developed with ribbed skeleton,PVC material,nested structure,buffer door,channel for fresh air dispersion,exhaust recovery pipeline and etc,and the self-developed plateau oxygen enrichers were involved in to establish a mobile oxygen-enriched room.The enrichers were divided into four grades of 20,50,70 and 100 m3/h,which were used to execute 8-h oxygen-enriched fresh air dispersion in the tent.The change curves of the fractions for oxygen and carbon dioxide were compared and analyzed at 5 disperse points in the tent.Results Optimal effect was acquired with 20 m3/h oxygen enricher,the oxygen concentration reached 27％ in the tent after 8-h dispersion,while the carbon dioxide fraction was 1 800 ppm (1 ppm=l×l0-6) and it took 3-h to raise oxygen concentration to 25％.Conclusion The tent combined with 20 m3/h oxygen enricher decreases the equivalent altitude from 5 000 m to less than 3 000 m,and is hopeful to be spreaded in the plateau troops after improvement.关键词
