| 摘要: |
| 针对现有载人航天器空气过滤净化技术效率低、净化能力单一、易造成二次污染的问题,提出基于YMn2O5莫来石催化剂协同臭氧催化氧化的人机共存一体化技术路线。利用柠檬酸凝胶溶胶法制备的YMn2O5催化剂通过X射线粉末衍射仪与扫描电子显微镜表征后发现,其表面具有丰富的活性位点,有利于在臭氧的协同作用下产生大量的还原性物质。该技术路线通过反应过程中产生的高活性O*,可对空气中挥发性有机化合物与病毒、细菌等微生物实现高效、绿色、低能耗的降解与消杀。基于此技术路线,结合3D建模与3D打印技术设计制作了空气净化和病毒消杀（Mcaton）一体化的原型机设备。针对空气中不同的挥发性有机污染物和病毒气溶胶,在密封舱内测试了原型机对气体污染物和病毒气溶胶的净化和消杀效果,验证了Mcaton技术可实现快速、高效净化各种挥发性有机污染物和病毒、细菌的消杀能力。 |

| Abstract: |
| In response to issues of low efficiency, single purification capacity and potential secondary pollution associated with existing manned spacecraft air filtration and purification technology, an integrated technology route of man-machine coexistence based on YMn2O5 mullite catalyst synergized with ozone catalytic oxidation was proposed. The YMn2O5 catalyst prepared by citric acid gel-sol method was characterized by X-ray powder diffractometer and scanning electron microscope. The results revealed that the catalyst′s surface possesses abundant active sites, which are conducive to the production of a large number of reductive substances under the synergistic effect of ozone. This technology route enables efficient, green and low-energy consumption degradation and elimination of volatile organic compounds, viruses, bacteria and other microorganisms in the air through the highly active O* produced during the reaction process. Based on this technology route, a prototype equipment integrating air purification and virus elimination (Mcaton) was designed and produced by combining 3D modeling and 3D printing technologies. For different volatile organic pollutants and virus aerosols in the air, the purification and elimination effects of the prototype on gas pollutants and virus aerosols were tested in a sealed chamber, which validated the ability of the Mcaton technology to achieve rapid and efficient purification of various volatile organic pollutants and elimination of viruses and bacteria. |
