Abstract

The invention discloses a secondary adsorption type oxygen generation system, by adopting a third molecule sieve absorption tower and a fourth molecule sieve absorption tower as main secondary oxygen generation equipment, the oxygen obtained by primary oxygen generation equipment is further purified so as to obtain a finished gas with high oxygen content; in addition, the invention adopts a vacuum pump to draw off a waste gas from a first molecule sieve absorption tower and a second molecule sieve absorption tower; due to a lower pressure generated by the vacuum pump, an adsorption effect of each molecule sieve absorption tower is good, which is convenient for improving the work efficiency and improving the oxygen content of the finished gas at the same time. The invention has the advantage of high oxygen generating efficiency and higher oxygen content of the finished gas.

Description

technical field [0001] The invention relates to an oxygen generating device, in particular to a secondary adsorption type oxygen generating system. Background technique [0002] The traditional molecular sieve adsorption oxygen production device is generally a one-stage adsorption oxygen production device, and its disadvantage is that the oxygen production efficiency is low and the oxygen content of the final product gas is low; in addition, this traditional one-stage adsorption system Oxygen devices in high-altitude areas, such as on the Qinghai-Tibet Plateau, have an unsatisfactory oxygen production effect and cannot meet the needs of users. Contents of the invention [0003] The purpose of the present invention is to provide a two-stage adsorption oxygen production system with high oxygen production efficiency and high oxygen content in the product gas. [0004] The technical solution for realizing the purpose of the present invention is: a two-stage adsorption oxygen ...
