Abstract:
Many researchers are working on multiple aspects of the COVID-19 pandemic including disease detection, treatment, and vaccine development. It is expected that there will be a large increase in passenger traffic at airports and railway stations and other public places. This paper proposes one solution to reduce the transmission of the disease through fomites such as passenger luggage and packages at bus/train stations and airports in the country. A tunnel system similar to the X-ray machines used for passenger luggage at airports has been proposed for disinfection of fomites. The system consists of eight 36 W T8 TUV bulbs illuminating each square meter area of the fomites on a conveyor belt for 10 s. For the standard airline luggage dimensions, 24 such bulbs will be distributed evenly on all four sides of the tunnel. The entry and exit points on the conveyor are shielded from the UV-C light leakage by placing thin plastic (such as acrylic) curtains. An optional non-foaming soap solution spray system may be used as an additional disinfection step. The toxic sodium hypochlorite solutions are not used in this design. Non-foaming soap solutions which are very effective against coronavirus and are non-toxic and biodegradable may be used as an optional disinfectant. It is to be noted that while the disinfection systems are designed to effectively mitigate the threat of coronavirus on the passenger fomite surfaces, these are purely based on theoretical calculations and have not been tested with actual viral particles. However, considering the time-sensitive emergency with COVID-19 pandemic, these systems will be very useful even without rigorous campaign of testing.
摘要:
许多研究人员正在研究COVID-19大流行的多个方面,包括疾病检测,治疗,和疫苗开发。预计机场和火车站等公共场所的客运量将有较大增长。本文提出了一种解决方案,以减少疾病的传播,例如在该国的公共汽车/火车站和机场的乘客行李和包裹。已经提出了一种类似于用于机场旅客行李的X射线机的隧道系统,用于对污染物进行消毒。该系统由八个36WT8TUV灯泡组成,将传送带上每平方米面积的fomites照明10s。对于标准航空公司的行李尺寸,24个这样的灯泡将均匀地分布在隧道的所有四个侧面上。通过放置薄的塑料(例如丙烯酸)窗帘,可以使输送机上的入口和出口点免受UV-C光泄漏的影响。任选的非发泡皂溶液喷雾系统可用作额外的消毒步骤。在此设计中不使用有毒的次氯酸钠溶液。对冠状病毒非常有效且无毒且可生物降解的非发泡肥皂溶液可用作任选的消毒剂。值得注意的是,虽然消毒系统旨在有效减轻冠状病毒对乘客表面的威胁,这些都是纯粹基于理论计算,并没有测试与实际的病毒颗粒。然而,考虑到COVID-19大流行的时间敏感紧急情况,即使没有严格的测试,这些系统也将非常有用。
