Description
Technical field
The present invention relates to vehicle-mounted oxygen generation system technical field, particularly relate to a kind of vehicle-mounted oxygen generation system.
Background technology
It is a kind of air separation technology that pressure swing adsorption air separates, and mainly relies on molecular sieve (critical component of pressure swing adsorption air separation equipment) that the adsorption capacity of each component gas in air reaches purpose at various pressures that separated by each component gas with the difference of the rate of adsorption. Pressure swing adsorption air separation equipment is divided into the equipment of making nitrogen and oxygen generating plant, is widely used in the industries such as chemical industry, electronics, medical treatment, coal, metallurgy, food storing. In pressure swing adsorption air separation equipment, its critical component molecular sieve is the particulate material (such as ball-type) that a large amount of micropore is contained in a kind of inside, is therefore afraid of oil, water and dust. And in prior art, for the consideration of cost and benefit, generally all adopt exhaust end base of oil injection threaded bolt formula air compressor machine as the compressed air source of THE PRESSURE SWING ADSORPTION OXYGEN GENERATING DEVICE, therefore the compression air produced of air compressor machine is contained within substantial amounts of oil and divides and moisture. Therefore, compression air wants the degree of depth to dewater before entering molecular sieve, oil removing, dedusting. It is generally adopted freezer dryer at present and can not meet its user demand, it is necessary to adopt absorbed type drying technique could meet needs. The desiccant in drying tower have to be regenerated with a part of unstripped gas due to absorbed type drying, wherein heatless regeneration absorption drier needs the unstripped gas of more than 15% to be used for regenerating, therefore the observable index of use absorbed type drying technique is higher, limits popularization and the use of absorbed type drying technique.
In addition, water is had very strong affinity by the molecular sieve used due to THE PRESSURE SWING ADSORPTION OXYGEN GENERATING DEVICE, so the dew points at normal pressure of the emptying end gas of oxygen generating plant is non-normally low, generally below-55 DEG C, it is especially suitable for the regeneration gas doing absorption drier, and in current PSA oxygen generator technique, the pressure of emptying end gas and flow are all not sufficiently stable, and it is directly discharged in air, fail emptying end gas is made full use of.
Conventional THE PRESSURE SWING ADSORPTION OXYGEN GENERATING DEVICE is generally adopted the equal baric flow journey of single step, the outlet adsorbing saturated adsorption tower carries out all pressure (" top-top all pressures " of being namely commonly called as) to regenerating adsorption column outlet completely, it is that the outlet adsorbing saturated adsorption tower carries out all pressures (" top-bottom is all pressed " that be namely commonly called as) to regenerating adsorption column inlet completely, and pressure rate does not effectively control, cause that above-mentioned equal baric flow journey can not effectively utilize oxygen-enriched air in the satisfied adsorption tower of absorption, and making air utilization ratio not high, oxygen specific energy consumption is high.
