The invention discloses a portable oxygen enrichment system for respiratory protection. The portable oxygen enrichment system comprises a fan (1), a film separation assembly (2), a vacuum pump (3) and a distribution pipeline (4), wherein the fan (1) is connected to the input end of the film separation assembly (2), the output end of the film separation assembly (2) is connected to the input end of the vacuum pump (3), the output end of the vacuum pump (3) communicates with the indoor space (6) through the distribution pipeline (4), a pre-filter is connected between the fan (1) and the film separation assembly (2), and the system also comprises a controller (5) for controlling the operation of the system. The portable oxygen enrichment system has the beneficial effects that air in a natural environment is taken, and oxygen in the air is filtered, purified and enriched in a film separation and permeation manner, the concentration of the produced oxygen-enriched air is larger than 26% (V/V), various pollutants including dust, aerosol (PM2.5), pollen, bacteria, mould, viruses and the like in the air are purified and filtered out, and a relatively independent healthy and safe oxygen-enriched breathing environment is created.

    本发明公开了一种呼吸防护用便携富氧系统,包括风机(1)、膜分离组件(2)、真空泵(3)、分配管路(4)。所述风机(1)连接膜分离组件(2)输入端,所述膜分离组件(2)的输出端连接真空泵(3)输入端,所述真空泵(3)的输出端通过分配管路(4)连通室内(6)。所述风机(1)和膜分离组件(2)之间连接前级过滤器。所述系统还包括控制器(5)控制系统的运行。本发明的有益效果为:该系统取自然环境的空气,用膜分离渗透方式过滤净化并富集空气中的氧气。制出的富氧空气浓度大于26%(V/V),并且净化滤除了空气中的各种污染物包括尘埃、气溶胶(PM2.5)、花粉、细菌、霉菌、病毒等,营造一个相对独立的健康、安全的富氧呼吸环境。
