Removal Efficiency of Virus Aerosols Using Carbon Nanotube Plasma
This work aims to remove virus bioaerosol by using carbon nanotube corona discharge plasma technology. The X virus bioaerosols are generated using a Collison nebulizer,as the challenged bioaerosols. Exactly how various factors,including the flow rate (30,60,and 90 lpm) and the operating voltages (-1.5,-3.0,-4.5,-6.0,and -7.5 kV),affect the bioaerosol reduction characteristics is also evaluated. Experimental results indicate that the corona discharge while using the carbon nanotube electrodes obviously decreases the threshold voltage of plasma. The removal efficiencies of X. virus bioaerosols by using the carbon nanotube corona discharge system at discharge voltages of-1.5,-3.0,4.5,-6.0,and -7.5 kV are 53%,60%,68%,89%,and 91%,respectively. Additionally,the corona discharge system that incorporates use of the carbon nanotube electrodes performs far superior to that incorporates the use of the stainless steel electrodes in terms of bioaerosol removal efficiency.
