Description

An air purifier with self-regenerating function

technical field

The utility model relates to the technical field of air purification equipment, in particular to an air purifier with a self-regenerating function.

Background technique

With the rapid development of science and technology and society, people have higher and higher requirements for the quality of life. Compared with outdoor air pollution, indoor air pollution has received more and more attention.

Indoor air pollution usually comes from flooring, wallpaper, paint, cigarette smoke, kitchen fume, electrical equipment, etc. It is mainly divided into three categories: the first category is solid particulate matter (PM2.5) that can be inhaled by the human body; the second category is volatile organic compounds (Volatile Organic Compounds), referred to as VOCs, and formaldehyde is more common in life; the third category Humans are microorganisms that can cause human health problems. Influenza A virus and coronavirus can be transmitted through the air.

Respirable solid particulate matter represented by PM2.5 is usually produced by the smoke and dust emitted by burning coal, gas or fuel oil in human production activities, which is usually caused by the combustion of fossil fuels, while indoors, second-hand smoke and cooking fumes from kitchen activities are other sources. main cause. When the concentration of inhalable solid particles such as PM2.5 is too high, it will cause great damage to the human body. Volatile organic compounds are the chief culprit of indoor air pollution, and the common representative of polluting volatile organic compounds is formaldehyde. Living in an environment with high TVOC content for a long time will cause immune dysfunction, dizziness, fatigue and other adverse symptoms.

In response to the increasingly serious air pollution problem, air purifiers are getting more and more attention in daily life. At present, the main technologies for air purification at home and abroad include: fiber filtration, activated carbon adsorption, electrostatic dust removal, low temperature plasma, photocatalysis, ultraviolet lamps and ozone technologies. Fiber filtration technology has a good filtration effect, but it needs to be replaced regularly, the life is short, and the maintenance cost is high; activated carbon adsorption technology has a wide range of adsorption capacity, but the absorption capacity is limited, it is easy to breed microorganisms, it needs frequent replacement, and it is easy to cause secondary pollution; Electrostatic dust removal technology has a good microbial purification effect, but it has almost no effect on gas pollutants; low-temperature plasma technology uses the high-energy particles generated to sterilize, and the plasma power is proportional to the degradation efficiency of VOCs, but the higher the plasma power, the more toxic by-products more; photocatalytic technology can quickly and effectively degrade VOCs, but when the photocatalytic reaction is incomplete, it is easy to produce toxic intermediate products; The location is limited; the ozone disinfection method has high requirements on the disinfection environment, requiring an ambient humidity greater than 70%, requiring personnel to avoid it during disinfection, and has a corrosive effect on metals.

Fly ash, the product of coal combustion, is a kind of solid waste to be treated, but its particles are porous honeycomb structure with a large specific surface area and high adsorption activity. The particle size range of the particles is 0.5-300 μm . Fly ash has a porous structure with a porosity as high as 50%-80%, and has a strong adsorption capacity. It is entirely possible to replace activated carbon as an adsorbent and become a more economical substitute. Experiments have proved that the main components of fly ash are aluminosilicates and oxide forms of silicon, aluminum, iron, calcium and other elements. As an adsorbent, it can withstand high temperature and corrosion, with small regeneration loss, stable chemical properties, and can be reused. The rate is high, and the desorption technology is simple and easy.
