Description

Air purifier with synergistic air purification effect of photocatalyst and activated carbon

technical field

The invention relates to an air purifying device, in particular to an air purifier used in a home room and an automobile driving room.

technical background

At present, most of the existing air purification devices only use filters to filter and purify the air, but this kind of air purification devices cannot remove harmful bacteria and harmful gases in the air, but only filter air dust, even if silver-loaded ion filters are used The net can only kill a small amount of bacteria and has a short validity period, and the use effect is poor; recently, some air purification devices that are beneficial to photocatalyst technology have appeared on the market. Although these devices can decompose some harmful gases and have some bactericidal effects, these devices There are defects in the setting of the photocatalyst, because the air purification method of these devices is single and inefficient, and the actual use effect is still unsatisfactory.

Contents of the invention

Aiming at the problems existing in the existing air purifiers, the purpose of the utility model is to provide a highly efficient air purifier capable of filtering, decomposing harmful gases in indoor air, and sterilizing.

The technical solution adopted by the utility model to solve the technical problems is: an air purifier, including a shell, a replaceable hollow activated carbon filter element inside the shell, a fan on the top, the air outlet of the fan leads to the outside of the purifier, and the fan The air inlet is connected with a photocatalyst air purification device. The housing of the photocatalyst air purification device is equipped with ultraviolet lamps and multi-layer quartz glass that can pass through ultraviolet light or a polymer material grille that can pass through ultraviolet light. The photocatalyst layer is attached to both sides of the grille. , fan and photocatalyst air purification device are placed in the activated carbon filter.

The beneficial effects of the utility model are: firstly, the harmful non-polar gas in the air is adsorbed by using the physical adsorption of activated carbon, and the air after being absorbed by the activated carbon enters the interior with ultraviolet lamps and multi-layer quartz glass that can transmit ultraviolet light. Or in the photocatalyst grille device of polymer materials that pass through ultraviolet light, because the photocatalytic effect of titanium dioxide photocatalyst is directly related to its area, by using a photocatalyst grille with high ultraviolet transmittance for air purification, the ultraviolet light irradiation and At the same time, the photocatalyst grille device is set in the direction of air flow in the activated carbon filter element, which greatly improves the air purification effect of the device.
