Problems solved by technology

[0011]Most laboratories are equipped with air conditioners. However, ordinary air conditioners do not have the function of replacing fresh air. The air supply cannot completely purify and kill the indoor air
[0012] If fresh air cannot be replaced, the air quality in the laboratory will continue to deteriorate, threatening the health of experimenters

Embodiment 1

[0062] This embodiment describes an indoor air purification device. Such as figure 1 and figure 2 As shown, the air purification device includes a lower air intake 1 , a return air passage 2 , an upper air supply 3 and an air purification and disinfection assembly 4 .

[0063] Wherein, the lower air outlet 1 is arranged on the ground or near the ground indoors, and the upper air supply outlet 3 is arranged near the ceiling indoors; here, the near-ground location and the near-ceiling location are relative terms.

[0064] The height position close to the ground is defined as the near-ground position, and the height position close to the ceiling is defined as the near-ceiling position. The return air channel 2 is vertically arranged, and its lower end is connected with the lower air outlet 1 , and its upper end is connected with the upper air outlet 3 .

[0065] In this embodiment, the return air channel 2 preferably adopts a square cylindrical structure, and of course, other...

Embodiment 2

[0124] This embodiment 2 also refers to an indoor air purification device. The inventive concept of the indoor air purification device is the same as the inventive concept of the device in the above embodiment 1, but there are differences in the implementation structure.

[0125] This embodiment 2 will describe these differences, and for relevant content that is not mentioned, please refer to the above-mentioned embodiment 1.

[0126] Such as Figure 9 and Figure 10 As shown, an indoor air purification device includes a lower exhaust tube 20, a return air passage, an upper air supply port, and an air purification and disinfecting assembly;

[0127] The down draft tube 20 is arranged on the ground or near the ground in the room, and is located in the middle of the room. This design allows the second embodiment to perform down draft from any direction in the circumferential direction of the down draft tube 20 .

[0128] The upper air supply port 3 is arranged at a position ne...

Embodiment 3

[0140] Embodiment 3 also refers to an indoor air purification device, except that the indoor air purification device is different from the above embodiment 2 in the following technical features, and other technical features can refer to the above embodiment 1.

[0141] Such as Figure 11 As shown, the air cleaning and disinfecting assembly 4 in the present embodiment 3 has one group or two groups (in Figure 11 Two groups of air cleaning and disinfecting assemblies 4) are shown in , and the air cleaning and disinfecting assemblies 4 are rectangular.

[0142] The above one or two groups of air purification and disinfecting components 4 are all installed on the indoor ground.

[0143] In this embodiment 3, the air purification and disinfecting assembly 4 also includes a dust primary filter layer 5, an acid gas filter layer 6, an IFD dust filter layer 7, an ultraviolet sterilizing device 8, a VOCs normal temperature catalyst layer 9 and an ozone decomposition filter layer 18.

Abstract

The invention discloses an indoor air purification device which comprises a lower air suction opening, an air return channel, an upper air supply opening and an air purification and disinfection assembly. The lower air suction opening is formed in the indoor position close to the ground, and the upper air supply opening is formed in the indoor position close to the ceiling. The air return channel is vertically arranged. The lower end of the air return channel is connected with the lower air suction opening, and the upper end of the air return channel is connected with the upper air supply opening. The air purification and disinfection assembly comprises a dust primary filtering layer, an acid gas filtering layer, an IFD dust filtering layer, an ultraviolet sterilization device, a VOCs normal-temperature catalyst layer and an ozone decomposition filtering layer which are sequentially mounted in the air return channel from bottom to top. According to the indoor air purification device, a bottom air suction mode is adopted, and heavy dirty air in a room can be rapidly sucked away; the air purification and disinfection assembly in the air return channel thoroughly purifies and sterilizes the dirty air; clean air is sent back into the room from a roof in a top air supply mode; and the indoor air quality can be thoroughly improved.

Description

technical field [0001] The invention belongs to the technical field of indoor air purification, and in particular relates to an indoor air purification device. Background technique [0002] Indoor air, there are a lot of air particulate matter PM (particulate matter) (also known as aerosol aerosol) and volatile organic compounds (VOCs) gas. [0003] PM2.5 refers to particulate matter with a diameter of Φ≤2.5 μm in the atmosphere, and PM1.0 refers to particles with a diameter of Φ≤1.0 μm in the air, also known as ultrafine particles. Particles with a diameter between 2.5 and 10 μm are called coarse particles, as opposed to fine particles. [0004] PM2.5 will pass through the respiratory tract, reach the human lungs, and directly enter the alveoli. [0005] The number of submicron particles accounts for nearly 100% of the total, while the weight only accounts for 2%-3% of the total [0006] Statistics show that the dust concentration in rural areas is about 100,000 grains / l...
