Coronavirus and its spread all over the world have been the most challenging crisis in 2020. Hospitals are categorized among the most vulnerable centers due to their presumably highest traffic of this virus. In this study, centrifugal isolation of coronavirus is successfully deployed for purifying hospitals’ air using air conditioners and ducts, suggesting an efficient setup. Numerical simulations have been used to testify the proposed setup due to the complexities of using experimental investigation such as high cost and clinical hazards of the airborne SARS-CoV-2 in the air. Results show that a 20-cm pipe with an inlet velocity of 4 m/s constitutes the best choice for the separation and purification of air from the virus. The proposed scalable method also efficiently separates larger particles, but it can separate smaller particles too. Numerical results also suggest installing the air purifying system on the floor of the hospitals’ room for maximum efficiency.

冠状病毒及其在世界各地的传播是 2020 年最具挑战性的危机。医院被归类为最脆弱的中心，因为它们的病毒流量可能最高。在这项研究中，冠状病毒的离心分离被成功地用于使用空调和管道净化医院的空气，这表明了一种有效的设置。由于使用实验研究的复杂性，例如空气中传播的 SARS-CoV-2 的高成本和临床危害，数值模拟已被用于验证所提议的设置。结果表明，入口速度为 4 m/s 的 20 cm 管道是从病毒中分离和净化空气的最佳选择。所提出的可扩展方法还可以有效地分离较大的颗粒，但它也可以分离较小的颗粒。
