An air purifier with an electronic net

technical field

The utility model belongs to the technical field of gas treatment, in particular to an air purifier with an electronic net.

Background technique

At present, air pollution caused by environmental damage and industrial waste gas has become a major problem facing our country. The "dust" in spring and summer and the "smog" in autumn and winter have seriously endangered people's health. Coupled with industrial waste gas, vehicle exhaust, coal combustion and other pollutants in the air such as fine dust, suspended particles, bacteria and viruses, the PM2.5 index in the atmosphere seriously exceeds the standard. In daily life, these substances can cause serious damage to the respiratory tract of the human body. People are exposed to smog for a long time, which can cause bronchitis, laryngitis, pneumonia, asthma, rhinitis, conjunctivitis and allergic diseases. In addition, the air quality is poor in smog weather, and middle-aged and elderly patients with poor resistance to cardiovascular disease and diabetes are very likely to aggravate their conditions due to lung and tracheal infections.

Filtration devices for removing contaminants from air or other gases are well known. Common methods of air filtration include household air filtration and commercial air filtration. Currently, various types of filters are commercially available. For example, HEPA filters (High Efficiency Particulate Air Filters) are commonly used to purify air by forcing the air through the filter, where particles are physically trapped by the filter. A HEPA filter is required to remove at least 99.97% of contaminants 0.3 microns or larger. Other types of commercial filters are also available, for example, cloth filters, stainless steel membrane filters, glass fiber filters and polyester filters, while for home air filters, the filtration principle is similar to commercial filters. However, if the above-mentioned air filter is used for a long time and the filter screen is not replaced frequently, not only the removal of pollutants in the air cannot be reduced, but the breeding of disease-bearing bacteria in the air will be aggravated, causing serious secondary pollution and other problems. .

At present, researchers have found that negative oxygen ions have a purifying effect on the air. The purification effect of the negative oxygen ions on the air means that the negative oxygen ions can well neutralize the positively charged pollution fine particles in the air and destroy the air between the particles. The same-sex charge makes the positively charged particles become neutral particles and loses stability and aggregates; but after a long time of use, due to the existence of a large number of negative oxygen ions, the solid particles are easily adsorbed to the wall surface, resulting in the black wall phenomenon. Appear.

Not only that, the box capacity of the existing air purifier is small, and the amount of purified air per unit time is less; the negative oxygen ions emitted collide with each other and lose energy, so the purified air has low purity and poor bactericidal power.
