Problems solved by technology

Adsorbent method is the most convenient and economical method, but its purification efficiency is low, and pollutants cannot be fundamentally removed, and the adsorbent is likely to become a hotbed for microbial reproduction again due to the enrichment of microorganisms, water and organic macromolecules. Pollution hazard
In addition, there are many methods of air purification, such as plant source purification technology, nanofiltration membrane technology, photocatalyst technology, etc. Although they have high purification efficiency, the technology is complicated and the cost is high

Embodiment 1

[0029] see figure 2 , the air cleaning device in the present embodiment comprises a water mist generator 100 and a plasma generator 200 ( figure 2 The part enclosed by the dashed box).

[0030] The water mist generator 100 may include a water mist outlet 101 and an ultrasonic generator. The water mist in the water mist generator 100 is atomized by the ultrasonic generator to produce water mist, and the water mist is discharged through the water mist outlet 101; The water mist generated by the fan is blown out of the water mist generator 100 through the water mist outlet. The water mist generator 100 can also use a commercially available humidifier, and the water mist can be generated by the humidifier.

[0031] The water mist generation speed of the water mist generator 100 in the embodiment of the present invention is adjustable. By adjusting the water mist generation speed of the water mist generator 100, the water mist spraying speed of the air purification device can ...

Embodiment 2

[0050] This embodiment focuses on the differences from the first embodiment, and the similarities will not be repeated. see image 3 The difference between the second embodiment of the present invention and the first embodiment is that the discharge electrode 204 adopts a mesh electrode. After the water mist is sprayed, it can pass through the mesh electrode. The mesh electrode increases the contact area between the water mist and the electrode, so that the water mist and plasma can react more fully. Same as Embodiment 1, the mesh electrode can also be placed in the inner cylinder 203, and the mesh electrode can also be provided with discharge protrusions 205, which will not be described in detail here.

Embodiment 3

[0052] This embodiment focuses on the differences from the previous two examples, and the similarities will not be repeated. see Figure 4 The difference between the third embodiment of the present invention and the previous two examples is that the water mist is no longer used as the main discharge object for discharge, but the air is discharged first, and then the generated plasma is blown into the water mist channel to fully mix with the water mist , A series of reactions occur to achieve the purpose of purifying the air.

[0053] A simulation study of the interaction between plasma and aqueous solution shows that some particles in air plasma, such as O 3 , N 2 o 5 , N 2 O, H 2 o 2 , HNO 2 , HNO 3 , They will undergo a strong chemical reaction after contact with water, the ozone and nitrogen oxides in them will be removed, and negative ions can be generated. Such as NO, O 3 , HNO 3 Etc. in water can generate negative ions O through a series of reactions 3 - , N...

Abstract

The invention discloses an air purifying device. The air purifying device is characterized in that a water mist passage used for allowing water mist to pass through and a plasma generator are included, the plasma generator comprises a discharge electrode, the discharge electrode is used for allowing plasma generated through high voltage discharge to pass through, and after the generated plasma and the water mist in the water mist passage are reacted and mixed, the water mist after reacting and mixing is further discharged through the device. According to the air purifying device, the plasma generated through discharge is used, abundant negative oxygen ions can be carried by the water mist, and thus the health of human bodies is promoted; particulate pollutants in air can be better coagulated through the weak ionized water mist, the concentration of PM2.5 can be lowered, ozone generation can also be better restrained through discharge in the water mist, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to the field of pollution prevention and control, in particular to an air purification device. Background technique [0002] In recent years, air pollution has attracted increasing attention. With the improvement of people's health requirements, air quality has been paid special attention. [0003] Generally speaking, pollutants in the air include harmful gases, dust and suspended solids, bacteria and viruses, etc. Among them, particulate matter with an aerodynamic equivalent diameter of less than or equal to 2.5 microns, which is what we often call PM2.5, is more harmful. Because of their small diameter, they can penetrate deep into the respiratory tract, bronchi and even alveoli, directly affecting the respiratory function of the lungs. Especially when it contains bacteria or toxic substances, it can cause diseases such as cancer and pose a great threat to human health. [0004] There are many traditional indoor air purifica...
