Description

Technical Field

[0001] This utility model relates to an air purification device. Background Technology

[0002] As people's demands for indoor air quality continue to increase, indoor air disinfection and purification products have become more widespread. Existing air purification devices first pass polluted air through a chlorine dioxide solution for disinfection and purification, and then directly pass the purified air into a photocatalyst for catalytic degradation. This type of purification device is relatively ineffective at disinfecting and purifying polluted air. Furthermore, the disinfectant used in the purification process flows along with the treated gas to the photocatalyst, causing partial deactivation of the photocatalyst and affecting its catalytic degradation effect on polluted air. Therefore, this type of air purification device has a poor overall purification effect on indoor polluted air. Utility Model Content

Furthermore, reference numerals and / or reference letters may be repeated in different examples of the embodiments of the present invention; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various implementations and / or arrangements discussed.

[0032] See Figure 1 As shown, this embodiment provides an air purification device, including a main body 1 with a hollow inner cavity, an air inlet 2 and an exhaust outlet 3 respectively opened at both ends of the main body 1, and an air purifier along the air intake direction (i.e., Figure 1 The intake assembly 4, fumigation assembly 5, absorption assembly 6, photocatalytic assembly 7, and exhaust assembly 8 are arranged sequentially in the main body 1 (in the direction of the arrows in the text).

[0033] In this embodiment, the main body 1 is rectangular in shape, the air inlet 2 is located on the end face of the right end of the main body 1, and the air outlet is located on the side face of the left end of the main body 1.

[0034] The fumigation assembly 5 includes a storage tank 51 for storing an aqueous chlorine dioxide solution and an ultrasonic atomizer 52 disposed in the storage tank 51 and located below the liquid surface. In this embodiment, by setting several ultrasonic atomizers 52 at the bottom of the storage tank 51, the aqueous chlorine dioxide solution in the storage tank 51 is ultrasonically vibrated, causing chlorine dioxide gas to diffuse above the liquid surface. This allows the polluted air rising from the aqueous chlorine dioxide solution to come into contact with and mix with this portion of chlorine dioxide gas before entering the absorption assembly 6, thereby being further disinfected and purified, thus improving the disinfection and purification effect on the polluted air.

[0035] See Figure 3 As shown, the absorption assembly 6 includes an absorption tank 61 for water storage, an air inlet pipe 62 with one end inserted into the absorption tank 61, and an air outlet pipe 63 with one end inserted into the absorption tank 61. The other end of the air inlet pipe 62 extends out of the absorption tank 61 and is located above the liquid surface in the liquid storage tank 51, so as to introduce the polluted air after being disinfected and purified by chlorine dioxide gas into the absorption tank 61, absorb the chlorine dioxide gas in the water in the absorption tank 61, and introduce the polluted air into the photocatalytic assembly 7 through the air outlet pipe 63.

[0036] Specifically, the photocatalytic component 7 includes a photocatalytic treatment chamber 71, an ultraviolet light source 72 disposed in the photocatalytic treatment chamber 71, and a titanium dioxide nano-coating. The other end of the exhaust pipe 63 extends out of the absorption cell 61 and is located in the photocatalytic treatment chamber 71. The exhaust pipe 63 allows water-insoluble polluted air in the absorption cell 61 to be introduced into the photocatalytic treatment chamber 71. In this embodiment, the ultraviolet light source 72 is an ultraviolet lamp with a main wavelength of 300-400nm.

[0037] See Figure 4 As shown, the photocatalytic component 7 also includes multiple sets of adjustment units 73 arranged sequentially and at intervals in the photocatalytic processing chamber 71 along the air intake direction. Each set of adjustment units 73 includes multiple adjustment plates 731 that are parallel to each other and arranged at intervals perpendicular to the air intake direction, and a connecting rod 732 for connecting all the adjustment plates 731. The connecting rod 732 is connected to the main body 1 through its two ends, and a titanium dioxide nano-coating is coated on the adjustment plate 731.

[0038] In this embodiment, the adjustment plate 731 is oriented adjustablely in the photocatalytic treatment chamber 71. This setting allows for adjustment of the residence time of polluted air within it, thereby adjusting the catalytic degradation effect on the polluted air.

[0039] By setting up an absorption tank 61 between the liquid storage tank 51 and the photocatalytic treatment tank 71, not only can the chlorine dioxide gas carried out by the polluted air be absorbed, preventing it from entering the photocatalytic treatment tank 71 and causing partial deactivation of the titanium dioxide nano-coating, thus ensuring the catalytic degradation effect on the polluted air; it can also recover the chlorine dioxide gas, preventing it from escaping and causing odors in the air, and reducing purification costs.

[0040] See Figure 1 As shown, the air purification device also includes a first partition 9 disposed in the main body 1 to separate the liquid storage tank 51 and the absorption tank 61, a first hole 91 opened on the first partition 9, and an air inlet pipe 62 passing through the first hole 91. This arrangement can isolate the liquid storage tank 51 and the absorption tank 61, preventing chlorine dioxide gas from diffusing into the absorption tank 61.

[0041] See Figure 1 As shown, the air purification device also includes a second partition 10 disposed in the main body 1 to separate the photocatalytic treatment chamber 71 and the exhaust assembly 8, and a second hole 101 formed on the second partition 10. This arrangement allows polluted air to enter the exhaust assembly 8 only through the second hole 101, increasing the residence time of polluted air in the photocatalytic treatment chamber 71 and further improving the photocatalytic degradation effect on polluted air.

[0042] See Figure 2 As shown, the air intake assembly 4 includes a pipe 41 connected to the air intake 2 and located in the liquid storage tank 51, a filter screen 42 disposed in the pipe 41, and a one-way valve 43. In this embodiment, the pipe 41 extends to the bottom of the liquid storage tank 51. This arrangement not only allows the polluted air to contact the chlorine dioxide solution for as long as possible to improve the disinfection and purification effect, but also prevents chlorine dioxide gas from leaking into the air through the air intake 2.

[0043] See Figure 1 As shown, the exhaust assembly 8 includes a filter adsorption chamber and an adsorption material (not shown in the figure) filled in the filter adsorption chamber, and the exhaust port 3 is connected to the filter adsorption chamber.

[0044] The aforementioned air purification device also includes an intake pump (not shown in the figure) connected to the air inlet 2 and / or an exhaust fan (not shown in the figure) connected to the exhaust outlet 3. By adjusting the power of the intake pump and / or the exhaust fan, the flow rate and residence time of polluted air in the main body 1 can be controlled to control the purification effect on the polluted air.

[0045] The working process of this embodiment is described in detail below:

[0046] Turn on the ultrasonic atomizer 52 to vibrate the chlorine dioxide solution, so that chlorine dioxide gas is diffused above the liquid surface in the storage tank 51;

[0047] Turn on the intake pump and / or exhaust fan to draw polluted air from the outside into the storage tank 51 through the intake assembly 4. The polluted air moves upward from the bottom of the chlorine dioxide solution, rises to the surface and mixes with the chlorine dioxide gas, and then enters the absorption tank 61 through the intake pipe 62. The absorption tank 61 absorbs the chlorine dioxide gas therein, and then the polluted air enters the photocatalytic treatment chamber 71 through the exhaust pipe 63.

[0048] Turn on the ultraviolet light source 72 and adjust the angle of the adjustment plate 731 in the adjustment unit 73 so that the polluted air is photocatalytically degraded in the photocatalytic treatment chamber 71. Then the polluted air enters the filter adsorption chamber through the second hole 101 and is further filtered and adsorbed. Finally, it is discharged from the exhaust port 3.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
