Hydrogen peroxide disinfection machine is a disinfection equipment that can be used in various environments to disinfect and sterilize. It is often used by hospitals to disinfect and sterilize patient rooms, operating rooms, and other rooms, in order to reduce the phenomenon of bacterial transmission. So in densely populated spaces like hospital wards, using hydrogen peroxide disinfection will not cause harm to the human body or have poor disinfection effects? The answer is that when using a hydrogen peroxide disinfection machine, personnel can stay inside. What is its disinfection principle?

Indoor air can be filtered by a hydrogen peroxide disinfection machine to remove larger dust particles, and then various odorous gases in the air can be removed by an activated carbon filter. The plasma generator in the hydrogen peroxide disinfection machine is a special high-voltage positive and negative ion generator. The generation of positive ions relies on the serrated positive electrode continuously producing high-energy and high concentration positive ions. We need to use positive ions for disinfection and determine how many positive ions are needed based on the indoor volume.
The high concentration of positive ions causes bacteria and inhalable particulate matter (including haze PM2.5) in the air to be extremely surrounded by positive ions, allowing them to quickly obtain saturated electrical energy. The flat positive electrode has a high electrostatic field strength (8000V high voltage), and charged particles and bacteria will quickly adsorb onto the positive electrode plate. The positive electrode plate device is filled with positive ions.
Under the action of positive ion permeation, bacterial electrolytes are destroyed, cell membranes are disrupted, leading to death. At the same time, the plasma generator can also generate high concentrations of negative ions through a high-voltage electric field of 15000V. When both positive and negative ions are present, they have a charge neutralization effect, which can more effectively kill various bacteria in the air. At the same time, this process also requires negative ions, so in the design process, the concentration of negative ions in the hydrogen peroxide disinfection machine was designed to be twice that of positive ions, leaving half of the negative ions after neutralization of the positive and negative ion charges.
Negative ions are captured by oxygen in the air and become negative oxygen ions. Negative oxygen ions mainly have functions such as sterilization, smoke reduction, deodorization, and formaldehyde removal. Because negative oxygen ions can cause various particles, dust, and charges to accumulate, and can decompose harmful gases, kill bacteria and viruses, eliminate smoke odor, thereby achieving the goal of changing the air structure, purifying and disinfecting indoor air.
The above is the principle of disinfection and sterilization of hydrogen peroxide disinfection machine. The final product of hydrogen peroxide disinfection machine is water and oxygen, so it can achieve the coexistence of human and machine in one room.
