Abstract

In this project, a prototype of a purificator for closed environments was designed and implemented, based on the application of ultraviolet radiation (254 nm), as a solution to the high rate of coronavirus infection, especially by aerobic action as a result of human activity in spaces with low ventilation and crowded areas. Three stages were defined for its development: theoretical foundation, design and construction. The prototype was designed around a main structure of stainless steel and PLA structures obtained through 3D printing; including external disinfection components such as the air filter. The conceptual design was carried out based on research and experimentation associated with the pathogenesis of SARS-CoV-2. Regarding the construction, the prototype was oriented to offer ease of assembly and deployment of the components, in addition to providing flexibility to the interconnection of the components. Finally, the tests were carried out in relation to the dose reached by the device, obtaining values above the virus inactivation threshold. With this, the functional prototype of a digitally controlled air purificator oriented to the inactivation of SARS-CoV-2 was obtained.
