Description
Technical field
The utility model belongs to molecular sieve omnibus control system technical field, in particular to a kind of using split-type design
Vehicle-mounted oxygen apparatus of oxygen supply processed.
Background technique
Generally, the anoxic height above sea level of medical definition is 3000m, and 3000 meters of China's height above sea level or more of high original area accounts for about
The a quarter of land national territorial area, plateau border line length account for about 1/5th of land boundary line.It is high in high altitude localities
The various high altitude diseases that former anoxic causes cause to seriously affect to plateau officers and men's physical and mental health, while also jeopardizing the defence of country
Safety.Altitude environment is trained to my army officers and men and combat duty proposes huge test.Under altitude environment, oxygen uptake is to solve
High altitude anoxia, the effective way for ensuring combat effectiveness of the troops.
Currently, common oxygenerating technology mainly includes Deep Cooling Method, membrane separation process, pressure swing adsorption method, chemical-agent technique, electrolysis
Method.Wherein the device is complicated for deep cooling, invests huge, operating cost height；Since highlands is scarcely populated, a deep cooling is built
Oxygen generating station, small scale are economically uneconomical；Scale is big, and production needs imbalance, therefore is not suitable for plateau and uses.Chemical legal system oxygen institute
It needs that consumption of raw materials amount is big, at high cost, production capacity is small, is not suitable for mass production oxygen, is not suitable for plateau and uses.It is electrolysed legal system oxygen
Power consumption is too big, the every production 1m of electrolysis water oxygen3Oxygen power consumption about 12~15kW h, be not suitable for mass production oxygen；Separately
Outside, electrolysis water oxygen generates hydrogen simultaneously, and hydrogen belongs to flammable explosive gas, and there are security risks, therefore unsuitable plateau makes
With.UF membrane legal system oxygen production oxygen concentration is low, generally 27%~45%, is unable to satisfy the demand of highland oxygen-feeding, altitude emergency treatment, and
Since plateau sand and dust are more, seperation film is easily blocked, therefore is not suitable for plateau and is used.Pressure swing adsorption method can produce 90% or more concentration
Oxygen, oxygen-producing amount is changeable, rises to several hectosteres per hour from per minute 1；Product form is flexible, can be portable
It is formula, vehicular, movable type, fixed；The production oxygen time is short, and device is simple, and installation and transportation are quick, and failure rate is low, for ease of maintenaince, from
Dynamicization degree is high, and easy to operate, low energy consumption, only 0.4 kW h/m3.Therefore, highlands is using pressure-variable adsorption legal system oxygen
It is most economical, conveniently, reliable and flexible method for producing oxygen through.
The research of external oxygenerating technology and equipment is more widely answered with system, corresponding product in place and army in detail
With.In recent years, the research of China's Technology for oxygen making over plateau and equipment makes some progress, and on the equipment vehicle of part plateau
Mating molecular-sieve oxygen generator.But existing molecular-sieve oxygen generator is both designed as all-in-one machine, and is mounted in vehicle cabin and occupies sky
Between it is larger, and the operating members such as control switch of product are on oxygenerator, farther out away from operator, are not easy to multiply load person's operation
And real-time monitoring product working status.Meanwhile oxygenerator product noise at work, multiply load person for a long time by noise effect, work
Efficiency decline.
Based on this, in conjunction with military vehicle actual installation demand, the vehicle-mounted oxygen oxygen supply processed of a split type structure of utility model
Device is particularly important.
