General medical air disinfection machine The main technologies of medical air purifier are:
1, electrostatic dust sterilization technology
1) Electrostatic dust removal: It can filter dust, smoke and bacteria smaller than cells, and avoid diseases such as lung disease, lung cancer and liver cancer.
The most harmless to the human body in the air is dust less than 2.5 microns, because it can penetrate cells and enter the blood. Popular pollution machines use filter paper to filter the dust in the air, which is easy to infiltrate the filter holes, and the dust accumulates more, not only No sterilization consequences, and easy to form a secondary purification.
2) Electrostatic sterilization: The electrostatic tungsten wire releases 6000 volts of high-voltage static electricity, which can completely kill bacteria and viruses attached to the dust and avoid diseases such as colds and epidemics. The sterilization mechanism is to destroy the bacteria capsid protein. Polypeptide chain and damage RNA.
Low temperature asymmetric plasma air pollution technology
2, HEPA filtration technology
HEPA is the abbreviation of HighEfficiencyParticulateAirFilter. HEPA filter consists of a stack of sub-glass fiber membranes that continue to fold back and forth, forming a wave-like gasket for placing and supporting the filter boundary.
3, ion wind technology
Ion wind medical air purifier technology also adopts more technologies, but its pollution effectiveness is yet to be tested. Ion wind medical air purifier is supposed to adsorb particles to the charged metal blades in the polluter, and the blades are propelled by components. Air, which constitutes the airflow, the negative ions and positive ions attract each other, and the particles and smoke in the air are attached to the blades.
4, negative ions
Negative ions are a kind of negatively charged gas ions in the air. Most of the free electrons generated by the ionization of air molecules under the influence of high pressure or strong rays are obtained by oxygen. Therefore, the air negative ions are often collectively referred to as "negative oxygen ions". The molecular formula of the negative ion is O2-(H2O)n, or OH-(H2O)n, or CO4-(H2O)n. The air negative ion with environmental protection function here refers to the first two small molecule negative ions.
5, activated carbon
Activated carbon is a very small carbon particle with a large surface area, rich micropores, and strong adsorption capacity. Because the carbon surface has a large surface area, it can be in full contact with gases (impurities). Gas (impurities) are adsorbed by micropores, causing pollution effects.
Photocatalyst (Photocatalyst), also known as photocatalyst (Lightcatalyst), is a general term for semiconductor materials with titanium dioxide (TiO2), which can not change itself under the illumination of light, but can enhance the chemical reaction. Under the illumination of the light source, it can apply the catalytic effect (oxidation recovery response) of the energy of the specific wavelength light source, so that the surrounding oxygen and water molecules provoke the active ionic groups such as OH^- and O^2-, which are free. The base can simply differentiate all inorganic materials and local inorganic materials that are harmless to the human body or the situation.
7, formaldehyde clearing agent
The high-end bio-engineering technology from Europe, based on the fact that some plants receive formaldehyde, extracts the essence from dozens of natural plants, and adds the active ingredients through special techniques. This product is an aqueous liquid, colorless, tasteless and odorless. No volatility (except moisture), it can automatically capture free formaldehyde and constitute a fluctuating solid material. Once used, the result is quick and durable.
8, ozone (reactive oxygen technology)
The gaseous thick layer of ozone is blue with a special smell. When the concentration is high, it is similar to the chlorine gas; the liquid ozone is dark blue, and the solid ozone is purple and black.
Medical air purifier
Ultraviolet light is a general term for the wavelength of radiation in the electromagnetic spectrum from 0.01 to 0.40 micron. It can not cause people's vision. The wavelength of the electromagnetic spectrum is 0.01-0.04 micron radiation, which is the radiation between the visible purple end and the X-ray.
Ultraviolet light with a wavelength of 200-290nm can penetrate the cell membrane of bacteria and viruses, damage nucleic acids (DNA), and enable cells to reproduce. It can reach the consequences of rapid sterilization. Short-wavelength ultraviolet light with wavelength below 200nm can differentiate O2 molecules and generate The combination of O* and O2 produces ozone O3. Ultraviolet rays and ozone have strong oxidative differentiation and the ability of inorganic molecules including malodor, and the synergistic effect of UV/O3 is used to promote weak power in air pollution disposal.
