The invention belongs to an air separation technology, and relates to a single-phase membrane onboard oxygen and nitrogen separation system. The system is characterized by comprising an electric control on-off valve (1), a filter (2), a pressure stabilizer (3), a heat exchanger (4), a heater (5), a temperature sensor (6), a single-phase ceramic membrane assembly (7), a flow limiter (8), an oxygen concentration sensor (9), a first one-way valve (10), a first flame suppressor (11), a central wing fuel tank (12), a ventilation box (13), a second flame suppressor (14), a pressure sensor (15), a second one-way valve (16), a gas storage tank (17), a position change valve (18), a mixing ratio regulator (19), a mask (20), and a controller (21). According to the single-phase membrane onboard oxygen and nitrogen separation system structure, separated nitrogen fills an oil tank while separated oxygen is used for breathing of a pilot, the structure is simple, no moving component exists, reliability is high, the air entraining amount is reduced, resource utilization is facilitated, waste gas emission is reduced, and stealth of an aircraft is facilitated.

    本发明属于空气分离技术,涉及一种单相膜机载氧氮分离系统。其特征在于:它包括电控通断阀(1)、过滤器(2)、稳压器(3)、热交换器(4)、加热器(5)、温度传感器(6)、单相陶瓷膜组件(7)、限流器(8)、氧浓度传感器(9)、第一单向阀(10)、第一火焰抑制器(11)、中央翼油箱(12)、通气箱(13)、第二火焰抑制器(14)、压力传感器(15)、第二单向阀(16)、储气罐(17)、换位阀(18)、混合比调节器(19)、面罩(20)和控制器(21)。本发明提出了一种单相膜机载氧氮分离系统结构,分离出氮气充填油箱,同时分离出的氧气用于飞行员呼吸,结构简单,无运动部件,可靠性高,降低了引气量,有利于资源利用,减少了废气排放,有利于飞机的隐身。
