Embodiment 1

[0029] see figure 1 , shown in the figure is a schematic structural view of the air purification device according to the present invention, which is installed in a centralized air-conditioning air purification system. At the return air outlet of the air conditioner, a module insertion port is provided, and the module insertion port is used for inserting the plasma purification module 1 . After the plasma purification module 1 is inserted, the air intake from the return air outlet of the air conditioner is purified and sterilized by the plasma purification module 1 .

[0030] Plasma purification module 1 is composed of electric field plate 2 and photocatalytic net 3 and activated carbon fiber net 4 arranged on both sides of electric field plate. Photocatalytic net 3 and activated carbon fiber net 4 are respectively arranged on both sides of electric field plate 2 for dust removal and filtration.

[0031] see figure 2 , image 3 , the electric field plate 2 includes a cuboid...

Embodiment 2

[0045] see Figure 5 , the plasma purification module can be installed in the purification device of the fan coil air conditioner. Firstly, according to the standard specification of the return air outlet of this type of air conditioner, a plasma purification module of a corresponding size is made, and corresponding module inlets are designed at the return air outlet of the air conditioner. When assembling, insert the plasma purification module into the power supply, and then fix the plasma purification module. (centrifugal fan air inlet) all the other are with embodiment 1.

Embodiment 3

[0047] see Figure 6 , The plasma purification module can be set in the air purification device of the cabinet type air conditioner. Specifically, the plasma purification module of the corresponding standard specification is designed according to the size of the air outlet of the cabinet type air conditioner, and then the plasma purification module is assembled at the air outlet of the cabinet type air conditioner. All the other are with embodiment 1.

[0048] The purification device of the present invention prepares titanium dioxide nanomaterials on the electrode plate of the electric field to form a high specific surface area and high oxidizing titanium dioxide film, and uses the nitrogen ultraviolet wavelength generated by plasma discharge to excite and generate high-performance active free radicals. Disinfect and sterilize, degrade organic waste gas. And it is suitable for the air of the air-conditioning system with large air volume and high flow rate to carry out instant...

Abstract

The invention discloses a plasma nano photocatalysed air purifying and sterilizing device for an air-conditioning system. A plasma purifying module used for purifying air is arranged at a return air inlet of the air-conditioning system and is provided with a shell connected with the return air inlet of the air-conditioning system, wherein a dust collecting plate forming an electric field and a discharge serration plate are arranged in the shell; the two poles of the electric field are connected with a micropulse AC / DC superimposed plasma power supply; and an insulating barrier layer with a high specific surface area and high catalytic oxidation is uniformly coated on a plate electrode. The insulating barrier layer is a titanium dioxide thin film with the high specific surface area and the high catalytic oxidation. In the purifying device, the plate electrode of the electric field is made of a titanium dioxide nano material to form the titanium dioxide thin film with the high specific surface area and high oxidability; and the purifying device disinfects, sterilizes and degrades organic exhaust gas by using nitrogen ultraviolet wavelength released and generated by plasma discharge to activate to generate high-performance active radicals.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a plasma / nano photocatalytic air purification and disinfection device applied to an air conditioning system. Background technique [0002] Urban air pollution and the modernization of the indoor environment have led to a significant decline in indoor air quality, and even the pollutant indicators are dozens of times higher than outdoors. Therefore, indoor air purification, disinfection and sterilization are very important to human health. [0003] Indoor air purification generally uses room purifiers and commercial air-conditioning disinfection and purification devices. [0004] Looking at domestic and foreign indoor air purification technologies generally include: filtration technology, adsorption technology, photocatalytic technology and ozone oxidation technology. [0005] 1. Filtration technology - it is a method to separate solid or liquid particles from the air f...
