Problems solved by technology

[0003] The existing EMUs only have a fresh air system, which cannot increase the oxygen concentration in the compartment
[0004] At the same time, when the EMU fails, its power system cannot supply power to the fresh air system. At this time, the oxygen concentration in the compartment will be further reduced, which will pose a threat to the safety of passengers.

Embodiment

[0040] Embodiment principle:

[0041] When the EMU is in normal operation, the on-board air compressor 7 is running, and the air pressure monitoring device 37 monitors the air pressure output by the on-board air compressor 7. When the air pressure is high, the first air circuit valve 9 is closed, and the second air circuit valve 10 is opened. The air output by the vehicle-mounted air compressor 7 reaches the first adsorption tower 2 and the second adsorption tower 3 through cooling and filtering of the air pretreatment device 35 (prior art), and the first adsorption tower 2 and the second adsorption tower 3 After nitrogen and oxygen separation, it is output by the personal use terminal 4 and the oxygen diffusion terminal 34. The personal use terminal 4 can adopt forms such as oxygen masks, and the oxygen diffusion terminal 34 can adopt forms such as air outlets. internal oxygen concentration.

Abstract

The invention discloses a double-gas-path multi-separator oxygen production and supply system, and relates to the technical field of oxygen production and supply systems. The system comprises an AB adsorption tower, a CD adsorption tower, an individual terminal, a dispersion terminal, a first gas circuit connecting pipe, a vehicle gas source, a second gas circuit connecting pipe, a standby air compressor, a first gas circuit valve group, a second gas circuit valve group, an air pressure monitoring device, an oxygen sensor, a closed-loop control system and the like. The system preferentially utilizes a vehicle compressed air source, nitrogen and oxygen separation is performed through two groups of adsorption towers, so that the oxygen concentration in a carriage environment is improved, and meanwhile, when the vehicle compressed air is monitored to be low in pressure and flow or a train power system breaks down, a redundant compressor air source is automatically started, and high-concentration oxygen is separated and output by the AB adsorption tower to be used by the individual terminal.

Description

technical field [0001] The invention belongs to the technical field of an oxygen supply system, in particular to an oxygen supply system with two gas paths and multiple separators. Background technique [0002] When the EMU is on the plateau, the oxygen concentration in the compartment is low, and passengers are prone to hypoxia. [0003] Existing EMUs only have a fresh air system, which cannot increase the oxygen concentration in the carriages. [0004] At the same time, when the EMU fails, its power system cannot supply power to the fresh air system. At this time, the oxygen concentration in the compartment will be further reduced, which will pose a threat to the safety of passengers. Contents of the invention [0005] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and propose an oxygen supply system with dual gas paths and multi-separators, which utilizes the vehicle-mounted air compressor to increase the oxygen c...
