摘要
针对空气氧氮分离的难题,提出了一种新型结构的"转匣式轴流压气机",取代传统的"转毂式轴流压气机"。其结构上的主要区别在于"转毂式"的叶片安装在轮毂上,只能实现空气压缩;而"转匣式"的叶片安装在内机匣内侧,在外机匣内旋转,可实现空气分离。论述了氧氮离心分离和转匣式压气机离心增压原理;阐述了空气采用漩流分离分流的技术可行性与实施途径;给出了离心法聚氧聚氮的实验装置简图,以实现空气压缩机、氧氮分离机和燃烧漩流器三机一体化,以期达到显著提高能源效率,充分利用资源和节能环保的目的。
To solve the difficult problem of oxygen and nitrogen separation from air,an innovative structure of 'rotating casing type axial compressor' is proposed to replace the traditional 'rotating hub type axial compressor'.The main difference of the two structures lies in the fact that the blades of a 'rotating hub type compressor' are installed on the wheel hub and can only realize air compression,while those of a 'rotating casing type compressor' are installed on the inside of an inner casing,rotating in an outer casing,thus effecting air separation.The authors have described the theories of oxygen and nitrogen centrifugal separation and the centrifugal pressure boosting of the rotating casing compressor.The merits,technical feasibility and application approach of air whirlpool separation were also expounded.A sketch of the centrifugal method-based test rig for oxygen and nitrogen collection was given,which can realize an integration of three devices,namely:an air compressor,an oxygen and nitrogen separator and a combustion whirlpool generator.The ultimate aim is to remarkably enhance energy source application efficiency,fully utilize resources as well as to save energy and protect the environment.
