Air purifying and heating system based on graphene and titanium dioxide

Abstract

The invention discloses an air purifying and heating system based on graphene and titanium dioxide. The system is used for purifying and heating air, and comprises an air input device, an air purifying and heating device and an air output device, wherein the air input device is fixedly connected with one end of the air purifying and heating device; the air output device is fixedly connected with the end, away from the air input device, of the air purifying and heating device; and the air purifying and heating device comprises a first cavity and a second cavity. According to the air purifying and heating system based on graphene and titanium dioxide, air can be purified through an air purifying layer made of graphene, purifying effect is good, a filter screen is not needed for filtering, and unnecessary operation of regularly replacing the filter screen is not needed; and heating can be carried out while air purification is carried out, and air heating temperature, air speed, air volumeand the like can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of air purification and heating, and in particular relates to an air purification and heating system based on graphene and titanium dioxide. Background technique [0002] Scientists discovered in 1972 that titanium dioxide (TiO2) can decompose water molecules under the irradiation of ultraviolet light (wavelength less than 380nm) to produce hydrogen gas. The photochemical properties exhibited by titanium dioxide make it synonymous with photocatalyst materials. Regarding "photocatalyst reaction", as the name implies, it is possible to use light energy to carry out catalytic reactions on the surface of photocatalyst materials. Under the irradiation of ultraviolet light, titanium dioxide (TiO2) has been found to have the function of decomposing organic molecules and bacteria. Odor, water purification and other effects. [0003] In recent years, although many semiconductor materials have been found to have ph...

Problems solved by technology

But this method cannot decompose formaldehyde, it can only capture temporarily

When the room temperature rises and the adsorption is saturated, formaldehyde will be released again, forming secondary pollution

[0006] Ventilation is difficult to eradicate formaldehyde hidden in cabinets and corners, and the ability of green plants to absorb formaldehyde is even more limited. How to accurately absorb formaldehyde and completely eliminate it is a problem that requires more attention

[0007] As a form of carbon atoms, graphene has a stronger adsorption capacity, so it is used in air and water pollution control. Graphene not only has the ability to purify formaldehyde and other air pollutants, but also sterilizes and inhibits bacteria. It can be seen from this , the purification products with graphene as the core are likely to change the traditional direction of pollution control
