Embodiment 1

[0035] [Example 1] The structure of the air cleaner

[0036] With reference to accompanying drawing below, attach TiO on the photocatalytic module 7 2 and reduced g-C 3 N 4 / rGO photocatalytic filter, the adsorption block is equipped with deodorizing filter, activated carbon filter, HEPA filter and antibacterial filter as an example to describe the specific implementation of the present invention in detail.

[0037] An air purifier that can make full use of sunlight, including a casing, an air intake bottom plate 4, an adsorption block 5, an air intake fan 6, and a photocatalytic block 7. The casing includes an upper box 1 and a lower box 2, The air intake bottom plate 4 at the bottom of the lower box body 2 is provided with an air inlet, and the top of the upper box body 1 is provided with an air outlet, and also includes a liquid crystal control display panel 8, a lens lens 9, and the air inlet is connected with the air inlet at the bottom of the purifier. The bottom plat...

Embodiment 2

[0043] Loaded with TiO in embodiment 1 2 The preparation method of the nickel foam mesh of photocatalyst is:

[0044] TiO was deposited by electrochemical deposition or pulling method 2 The photocatalyst is attached to the nickel foam mesh.

Embodiment 3

[0046] Loaded with g-C in embodiment 1 3 N 4 The preparation method of the foamed nickel mesh of rGO photocatalyst is:

[0047] will g-C 3 N 4 Mix it with graphene oxide (GO) at a ratio of 3:1 to form a slurry, completely immerse the foamed nickel mesh in the slurry, and first ultrasonicate for about 2 minutes to discharge the internal air, which is conducive to the entry of the slurry. After dipping for 20 minutes on each side, turn it over. After dipping, take it out and dry it at 50 degrees, and then dip again. Repeat 3 times. then load with g-C 3 N 4 / GO foamed nickel mesh was placed in 400ppm hydrazine hydrate and ammonia solution for 0.5h at 50°C, and g-C 3 N 4 / rGO's nickel foam mesh.

Abstract

The invention relates to an air purifier capable of utilizing sunlight fully. By the device, air can be purified in real time by sunlight, and an ultraviolet lamp tube is not required. A lens is mounted at the top end of the purifier, a TiO2 photocatalysis film is plated on the outer side of the lens, and ultraviolet light in the sunlight can be utilized; and meanwhile, the remaining ultraviolet light and visible light are focused on a photocatalytic block, energy density is increased, and the sunlight is utilized efficiently. The photocatalytic block consists of two foam nickel nets which areseparately loaded with TiO2 and g-C3N4 / rGO, the time for contact between air and a catalyst can be prolonged, and the catalytic efficiency is improved. An adsorption block which consists of a deodorization filter net, a HEPA filter net, an activated carbon filter net and an antibacterial filter net is mounted on the bottom of the purifier. Air enters the purifier from a gas inlet under the effectof a fan, and is successively purified by the adsorption block and the photocatalytic block. The purified air is discharged from a gas outlet, and catalytic degradation on the surface of a coated lens is further carried out.

Description

technical field [0001] The invention relates to an air purifier, in particular to an air purifier which can make full use of sunlight. Background technique [0002] With the development of society and human progress, environmental problems have become a major obstacle to the sustainable development of human beings, among which air pollution is particularly serious and poses a great threat to human health. Pollutants in the air such as dust, formaldehyde, toluene and PM2.5 can easily cause human respiratory diseases and are also one of the causes of many cancers. The problem of air purification needs to be solved urgently. In an open space, due to air circulation and other reasons, harmful gases are not easy to cause harm to the human body, but in small spaces such as desks and vehicle interiors, due to the existence of inevitable pollution sources, the limited air circulation leads to the enrichment of polluted gases, and more It is easy to cause harm to the human body who...
