Concept Design of a High-Voltage Electrostatic Sanitizer to Prevent Spread of COVID-19

这项研究的目的是开发一种高压静电消毒剂的概念设计，用于捕获和破坏可能在空气、水和食物等介质中传播的冠状病毒颗粒。在第一步，该项目将重点关注空气传播的COVID-19病毒颗粒，以防止病毒在空气中传播并减少人类接触。项目范围将扩大到利用高压杀灭离子水中微生物的可能性。一系列不同的食品和生物加工行业都可以从高压水杀菌剂中受益，因为已经观察到，当不同液体污染物的细胞膜暴露在高压电场中时，细胞膜发生不可逆的破坏，最终导致其破坏和液体消毒。

The proposed research aims to develop a concept design of a high voltage electrostatic sanitizer for capturing and destroying coronavirus particulates that could be traveling in a medium such as air, water, and foods. In the first step, the project will focus on airborne COVID-19 viral particles, in an effort to prevent airborne transmission of the virus and reduce human exposure. The project scope will be extended to the possibility of killing microorganisms in ionized water using high voltage. A range of different food and bioprocessing industries could benefit from a high voltage water sanitizer, as it has been observed that when cell membrane of different liquid pollutants is exposed to a high voltage electric field, irreversible breakdown of the cell membrane occurs which ultimately leads to their destruction and liquid sanitization. The device, which is going to be designed conceptually through this research work, would be an electrostatic sanitizer that uses high voltage to ionize air or water molecules containing viral or other microorganism particles and trap them. The current practice for removing airborne particles, whether high-efficiency particulate air (HEPA) purifiers or air ionizers, is successful in removing particles of biological origin like bacteria whose diameter are equal to 0.3 µm or larger. However, the COVID-19 virus is approximately 0.125 µm in diameter, which means that even the most powerful air filters would struggle to remove it from the air. Thus, this project aims at pushing the electrostatic sanitization boundaries towards large size viruses such as COVID-19 by a novel electromagnetic field analysis and design of electrodes and sanitizing partial discharge chamber.
