How does a plasma disinfection machine purify and disinfect the air?
With people's increasing attention to a healthy environment, air purification and disinfection have become an important need for homes and public places. Plasma disinfection machines, as an emerging air purification and disinfection equipment, have attracted much attention due to their high efficiency and green characteristics. Today we briefly introduce the working principle of plasma disinfection machines and their application in air purification and disinfection.
1. The concept of plasma
Plasma is a state of matter, parallel to solid, liquid and gas. It is a high-energy gas composed of freely moving electrons and ions. At room temperature, plasma can produce a variety of active substances, such as ozone, hydroxide ions (OH-) and superoxide (O2-), which play a vital role in air purification and disinfection.
2. The working principle of plasma disinfection machines
The basic working principle of plasma disinfection machines includes the following steps:
Ionization process: The gas inside the device (usually air or nitrogen) is discharged through a high voltage to form a plasma. The electric field accelerates the molecules in the gas, causing them to ionize, thereby generating a large number of free electrons and ions.
Active substance generation: Under the action of plasma, the molecules in the gas undergo cracking reactions to produce various active substances, the most common of which include ozone, hydroxide ions and hydrogen peroxide. These active substances are highly oxidizing and can effectively decompose and kill germs, viruses and harmful gases.
Purification and disinfection: When air passes through the plasma disinfector, the active substances react with microorganisms and harmful components in the air, destroying their structure, causing them to lose their activity or be oxidized and decomposed, thereby achieving air purification and disinfection.
3. Advantages of plasma disinfection machine
High efficiency: Plasma disinfection machine can kill up to 99.9% of bacteria and viruses in a short time, and has excellent removal effect on harmful substances in the air.
Environmental protection: Compared with traditional chemical disinfectants, plasma disinfection machines do not produce harmful chemical residues, and the disinfection process is more environmentally friendly.
Wide applicability: Plasma disinfection machines can be widely used in various places such as homes, hospitals, schools, offices, etc., providing people with a safe and healthy air environment.
Application examples
During the epidemic, the application potential of plasma disinfection machines was fully demonstrated. Many hospitals and public places have begun to adopt plasma disinfection technology to quickly and effectively disinfect the air and reduce the risk of virus transmission. In the home, plasma disinfection machines are used as an auxiliary means of air purifiers to help improve indoor air quality and protect the health of family members.
As a modern air purification and disinfection equipment, plasma disinfection machines have shown great potential in improving air quality and public health protection with their unique working principles and many advantages. Today, when people pay more and more attention to health and the environment, plasma disinfection machines will bring a safer and cleaner air environment to our lives. With the continuous advancement of science and technology, I believe that its application areas will be more extensive to protect human health.
