Description

High-efficiency composite air purifier

technical field

The utility model relates to a high-efficiency composite air purifier, which is a multifunctional air purifier compounded by multiple purification technologies such as dual-zone plasma electric field, nano photocatalyst reaction chamber, and long-term filter element. It belongs to the technical field of air purification devices.

Background technique

As we all know, the air purifiers with the largest sales volume on the market currently use filter mesh filtration and activated carbon adsorption technology. Its structure is simpler, and cost is lower, but its defect is more obvious. First, the filter screen can only filter dust and bacteria, but cannot destroy bacteria. Under suitable temperature and humidity conditions, the bacteria on the filter screen will multiply and cause secondary pollution. Moreover, the filter screen has small pore size and high resistance, which is easy to be blocked by floating mining. , the purification function will be lost in a short time. Second, activated carbon can absorb odors but cannot decompose them. It is only the storage and transfer of pollution; when the adsorption is saturated, if it is not replaced in time, the adsorbed substances will return to the room and cause new pollution. In addition, there is another kind of purification agent produced by ozone technology, which has the function of sterilizing and deodorizing, but if the concentration exceeds 0.1mg/m ³ , it will cause damage to the human body; at low concentrations, the effect of sterilizing and deodorizing is not obvious, and its harsh use Conditions limit its application in air purifiers.

The bacteria are electrocuted at the moment of contact with the plates, and the chemical bonds of some odor molecules are broken and degraded. Then the air treated by the electric field enters the nano photocatalyst reaction chamber. Under the joint action of temperature, pressure difference and ultraviolet light, other odors, toxic and harmful gases and residual bacteria in the air are decomposed into water and carbon dioxide through redox reactions. and inorganic harmless substances. The basically clean air finally passes through the long-term filter element to finally absorb the possible escape and residual odor and toxic and harmful gases.
