Description

一种适用于高原地区的便携式制氧机 Suitable for portable oxygen machine highlands

技术领域 FIELD

[0001]本发明涉及一种空气分离制氧技术,尤其为一种适用于高原地区环境的采用变压吸附方式分离空气制备氧气的便携装置。 [0001] The present invention relates to a portable air separation device for technical oxygen, especially at high altitude environment suitable for the preparative separation using pressure swing adsorption air oxygen.

背景技术 Background technique

[0002]我国幅员辽阔,海拔3000米以上的高原、高山地区,约占全国总面积的六分之一。 [0002] China has a vast plateau 3,000 meters above sea level, the mountain region, about one-sixth of the total area of ​​the country. 高原地区气候多变,寒冷、风大、空气稀薄,其中空气稀薄,大气压和氧分压降低,是高原环境对人体机体影响的主要因素。 Climate variability at high altitude, cold, wind, thin air, where the thin air, atmospheric pressure and reduced oxygen partial pressure, is the main factor of high altitude on human body. 世居在高原地区的少数民族,对高原环境已经适应,而对于长年生活在低海拔地区的人员来说,初抵3000米以上高原地区,由于大气压中氧分降低,肺泡气和动脉血氧分压也相应的降低,毛细血管血液与细胞线粒体间氧分压梯度差缩小,从而引起缺氧。 Ethnic groups in the highlands, have adapted to the environment on the plateau, and for many years people living in low-lying areas, it arrived in highland areas above 3,000 meters, due to lower atmospheric pressure Oxygen, alveolar gas and arterial oxygen dividing correspondingly reduced, between capillary blood and the oxygen partial pressure gradient of mitochondrial deficit, causing hypoxia. 高原地区缺氧对人体机体的影响,加之高原地区寒冷、大风、雨雪气候以及强紫外线照射,成为诸多高原病症诱发和加重因素。 Hypoxia at high altitude on human body, combined with the cold at high altitude, high winds, rain and snow weather and strong ultraviolet radiation, become a lot of altitude illness inducing and aggravating factors. 及时地补充氧气成为提高人体机体适应能力和减轻高原反应甚至是挽救生命的有效途径。 Timely replenishment of oxygen to be to improve the human body's ability to adapt and even alleviate altitude sickness is an effective way to save lives.

[0003]目前,已有多种制氧供氧设备可以在固定场所提供氧气,但对于移动人群,以往的供氧装置主要有氧气袋、小型氧气瓶等。 [0003] Currently, there are a variety of oxygen supply apparatus may be provided in a fixed place of oxygen, but for people on the move, the conventional aerobic bag main oxygen supply apparatus, a small oxygen bottles. 这类装置需要不断充氧,且氧气容量有限,既不方便使用,也不能保障供氧。 Such apparatus requires constant oxygenation, oxygen and limited capacity, inconvenient to use, would not protect oxygen. 为此,国内外都在着力研究开发便携式制氧机。 For this purpose, at home and abroad in efforts to research and development of portable oxygen machine. 考虑到变压吸附(PSA)方法制氧不但浓度高,而且不产生有害气体,因此,被国内外大多数便携式制氧机都采用该方法。 Considering the pressure swing adsorption (PSA) method not only high oxygen concentration, but does not produce harmful gas, thus, is both domestic and most portable oxygen generator using this method.

[0004]进入高原地区,随着海拔高度的增加,空气逐渐稀薄,大气压降低,PSA制氧机产氧量及浓度都将减小,使得制氧机在高原环境下性能明显有所下降。 [0004] into the plateau region, as the altitude increases, the air gradually thin, reducing the atmospheric pressure, the PSA oxygen production and oxygen concentration are reduced, so that the oxygen in the high altitude performance significantly decreased. 如何在不增加便携式制氧机体积重量的前提下保持制氧机制氧效率和氧气的利用效率,这已成为便携式制氧机进入高原地区使用所必须克服的技术难题。 How not to increase the utilization efficiency of the mechanism of oxygen to maintain oxygen and oxygen efficiency under the premise of portable oxygen volume weight, which has become a portable oxygen generator into the highlands use must overcome technical problems.

[0023] 1、本发明产生氧气的方法是变压吸附空气分离法。 [0023] 1, the method of the present invention is to produce oxygen pressure swing adsorption air separation process. 该方法利用沸石分子筛对气体吸附量随气体压力增加而增大和在相同气体压力下对氮气和氧气的吸附量不同的吸附特性而采取高压吸附、低压解吸的循环工艺从空气中分离出氧气。 The method using zeolite molecular sieve adsorption amount of the gas increases with increasing gas pressure and different amount of adsorption of nitrogen and oxygen adsorption characteristics taken at the same high pressure adsorption gas pressure, the low pressure desorption cyclic process of separating oxygen from air. 为了增加回收率和氧气纯度,PSA便携式制氧机的循环工艺中一般有均压步骤(特别是上均压步骤)和反吹步骤。 In order to increase the oxygen purity and recovery, PSA cyclic process in the portable oxygen concentrator generally pressure equalization step (in particular the pressure equalization step), and cleaning steps.

[0024] 2、本发明便携式制氧机采取了脉冲式输氧方式,避免呼气阶段和吸气末段氧气损失,少量的氧气供应能使使用者的血氧饱和度明显增加,弥补了便携式制氧机在高原地区连续流量一般小于ll/m in的限制。 [0024] 2, the portable oxygen generator of the present invention takes oxygen pulse mode, the last paragraph of the intake and exhalation phase to avoid loss of oxygen, a small amount of oxygen supply oxygen saturation can significantly increase a user to make up the portable system oxygen machines generally less than ll / m in a continuous flow restriction plateau region. 根据呼吸生理学原理,氧气进入小肺泡囊中比在大肺泡囊中的交换效率要高,因此,便携式制氧机在吸气的极早期高速输出氧气,氧气迅速进入小肺泡囊中,避免停留在气管和大肺泡囊中。 According to the principles of respiratory physiology, oxygen into the alveolar sacs small than large exchange efficiency in alveolar sacs in the higher, therefore, a portable oxygen machine quickly into the small alveolar sacs in the very early stages of high-speed output inhalation of oxygen, oxygen, avoid staying in in large airways and alveolar sacs. 本发明采取脉冲式供氧方式,不到900mL的氧气在使用效果上等同于连续流量的5L/min。 The present invention takes the pulse oxygen embodiment, oxygen 900mL less the same effect as in the use of a continuous flow of 5L / min.

[0025] 3、本发明便携式制氧机通过调节压缩机驱动电机电源的占空比来调节并提高压缩机驱动电机转速来增加制氧机的供氧流量,使本发明制氧机可随海拔高度增加,供氧流量略有增加,而氧气浓度则基本不随海拔的变化而变化,大致维持在91 %左右。 [0025] 3, the portable oxygen generator of the present invention is adjusted by adjusting the duty cycle and increase the power of the compressor drive motor to increase the rotational speed of the compressor drive motor oxygen supply flow rate of oxygen so that oxygen present invention may vary with altitude altitude increases, oxygen flow increased slightly, while the oxygen concentration is basically no change with altitude, largely unchanged at around 91%.

[0026] 4、本发明便携式制氧机存在较明显的节能效果,为了能在没有网电源的情况下工作,本发明便携式制氧机除了配置车载电源外,还配有内置可充电锂电池。 [0026] 4, exists in the portable oxygen generator of the present invention is more significant energy savings, in order to work in the absence of mains power, the portable oxygen generator of the present invention, in addition to configuring the vehicle-mounted power supply, but also has built-in rechargeable lithium battery. 为了使内置电池每次的使用时间尽量长,便携式制氧机设有几个档位,每个档位所对应的流量不同,能耗也不同,使用者可根据需要选择合适的档位,而不需要在任何情况下都处在最大能耗下运转使用。 In order to make the built-in battery using each time as long as possible, a portable oxygen concentrator has several stalls, each gear corresponding to different traffic, energy consumption is also different, the user can select the appropriate gear according to need, and in any case we do not need to operate at maximum energy use. 在输出压力相同时,转速越慢,能耗越小。 The output pressure is the same, the slower the speed, the smaller the power consumption. 便携式制氧机在氧气流量较小的档位下,电机电压占空比减少,以窄脉宽输入,压缩机的排气量也可相应减少,有效电压降低,能耗减少。 The portable oxygen concentrator of the oxygen flow at a smaller gear, to reduce the motor voltage duty cycle, pulse width narrower input, a corresponding displacement of the compressor can be reduced, the effective voltage is reduced to reduce power consumption.
