What is a plasma air sterilizer
Plasma (plasma) is an ionized gaseous substance composed of positrons and negative ions. These ions are generated by the ionization of atoms and atomic groups after partial electron deprivation. Movement is mainly controlled by electromagnetic force, and shows obvious collective behavior. It exists widely in the universe and is generally regarded as the fourth state of matter, except solids, liquids and gases. Plasma is a very good electrical conductor. It uses a cleverly designed magnetic field to capture, move and accelerate the plasma. The development of plasma physics has provided new technologies and processes for the further development of sciences such as materials, energy, information, environmental space, space physics, and geophysics.
Plasma is the fourth state of matter, unlike solids, liquids and gases. Matter is composed of molecules, which are composed of atoms, and atoms are composed of positively charged nuclei and negatively charged electrons around them. When heated to a sufficiently high temperature or other reasons, the external electrons will break away from the nucleus and become free electrons, just like the students play in the playground after class. The process of electrons leaving the nucleus is called “ionization”. At this time, the substance becomes a uniform “paste” composed of positively charged nuclei and negatively charged electrons, so people call it ionic pulp, and the total amount of positive and negative charges in these ionic pulps is equal. Therefore, it is almost electrically neutral, hence the name plasma.
What is a plasma air disinfection machine and what are its functions?
Compared with the traditional ultraviolet circulating air disinfection machine, the plasma air disinfection machine
Has the following six advantages:
1. Efficient sterilization Plasma sterilization and disinfection are very effective, and the action time is short, far behind high-intensity ultraviolet rays.
Second, the environmental protection plasma sterilization and disinfection are continuous, will not produce ultraviolet rays, ozone, and avoid secondary pollution to the environment.
3. Efficient degradable plasma sterilizer can also degrade harmful and toxic gases in the air while disinfecting the air. According to the report of the Chinese Center for Disease Control and Prevention, the degradation rate within 24 hours: 91% formaldehyde, 93% benzene, 78% ammonia, and 96% xylene. At the same time, it can effectively remove pollutants such as smoke and soot.
Fourth, low energy consumption The power of the plasma air disinfection machine is 1/3 of the ultraviolet disinfection machine, which is very power-saving. As far as the room of 150m3 is concerned, the plasma machine is 150W and the ultraviolet machine is more than 450W, which can save more than 1,000 yuan per year.
Fifth, long service life In the case of normal use of plasma disinfection machine, the designed service life is 15 years, while the ultraviolet disinfection machine is only 5 years.
Sixth, free consumables for life. The ultraviolet disinfection machine needs to replace a batch of lamps in about 2 years, and the cost is nearly 1,000 yuan. Plasma sterilizers do not require consumables for life.
In general, the normal depreciation cost of plasma air disinfection machine is about 1,000 yuan/year, while the relative depreciation cost of ultraviolet disinfection machine is about 4000 yuan/year. The work of the plasma disinfection machine is very environmentally friendly and harmless to medical staff and patients. Therefore, it is very wise to choose a plasma sterilizer for air disinfection.
