Description

Novel vehicle-mounted air purifier

Technical Field

The utility model relates to an air purifier technical field specifically is a novel vehicle-mounted air purifier.

Background

Numerous expert researches in the air environmental protection field of the United nations prove that ecological-grade anions (small-particle-size anions) can actively attack and capture small-particle dust particles, so that the small-particle dust particles are condensed and precipitated, and the dust particles with the particle size of 2.5 microns (PM2.5) and below, even particles with the particle size of 1 micron, in the air are effectively removed, so that the harm of the PM2.5 to the human health is reduced. The ecological negative ions have the air purification effect that the negative ions are combined with positively charged particles such as bacteria, dust, smoke and the like in the air and are aggregated to fall into balls to eliminate PM2.5 hazards, the anions are coincidently subjected to Brownian motion in the air, the Brownian motion is an effective method for eliminating tiny dust objects, and the anions are combined with floating dust to promote the floating dust to move Brownian so as to eliminate the floating dust. After the negative ions are combined with bacteria and microorganisms, the bacteria, viruses and microorganisms generate structural change or energy transfer, so that the bacteria, viruses and microorganisms die and no new strains are formed. Negative ions can be used for: the anion air purifier, the anion electric blower, the air conditioner, the anion comb, the anion face cleaning instrument, the anion spot removing instrument, the medical equipment and the like, and the anion air purifier, the anion electric blower, the air conditioner, the anion comb, the anion face cleaning instrument, the anion spot removing instrument, the medical equipment and the like are widely used.

The plasma technology is characterized in that under the action of an external electric field, a large amount of energy-carrying electrons generated by medium discharge bombard pollutant molecules, and firstly, in the process of generating plasma, the instantaneous high energy generated by high-frequency discharge is enough to open the chemical energy of some harmful gas molecules so as to decompose the harmful gas molecules into simple substance atoms or harmless molecules; the second is that the plasma contains a large amount of high-energy electrons, positive and negative ions, excited particles and free radicals with strong oxidizing property, and the active particles and part of odor molecules are combined in a collision way, so that the odor molecules are in an excited state under the action of an electric field. When the energy obtained by the odor molecule is larger than the binding energy of the molecular bond energy, the chemical bond of the odor molecule is broken and directly decomposed into simple substance atoms or harmless gas molecules formed by the single atoms. Simultaneously, a large amount of active free radicals such as OH, HO2, O and the like and O3 with strong oxidizing property are generated to chemically react with harmful gas molecules, and finally, harmless products are generated. The complex macromolecular pollutants are converted into simple micromolecular safe and harmless substances, or the toxic and harmful substances are converted into non-toxic and pollution-free substances to be degraded and removed. The plasma can be used to: the negative ion air purifier is used in industries such as a negative ion air purifier, chemical industry, mechanical hardware, medical equipment and the like.
