The invention discloses a method and a device for separating air through air pressurization, reflux expansion and internal compression and relates to a method and equipment for separating air by adopting heat exchange, rectification and reflux expansion at low temperature. During air separation, an expander for internally compressing anti-waste nitrogen serving as a working medium through air pressurization is used; the waste nitrogen is expanded at the low temperature and acts externally to provide cooling energy for a cooling box of a fractionating tower; in the whole separation process, a two-stage rectifying tower is adopted; the rectifying tower consists of a lower tower, an upper tower and a refrigeration evaporator arranged between the lower tower and the upper tower; operating pressure of the lower tower is less than 1.14MPa (G) and the operating pressure of the upper tower is less than 0.32MPa (G). By the method and the equipment, the quality of products is improved and the manufacturing ...
