Abstract

The invention provides a photocatalyst purification device, an air purifier and an air purification method, and belongs to the technical field of air purification. The photocatalyst purification device comprises a base material, a heating system and a light source device, wherein a photocatalyst and a water collecting and releasing material are attached to the surface of the base material; the heating system is suitable for heating the water collecting and releasing material; and the light source device is arranged on one side of the base material, and is suitable for irradiating the photocatalyst. According to the photocatalyst purification device provided by the invention, the photocatalyst and the water collecting and releasing material are attached to the base material, and the photocatalyst can generate a strong oxidizing substance under the irradiation of the light source device; and the water collecting and releasing material can collect moisture in the air at normal temperature, when the water collecting and releasing material is heated, the collected moisture can be emitted in the form of water vapor, the water vapor can serve as a carrier of the strong oxidizing substance while being emitted, the strong oxidizing substance is attached to the water vapor, and through diffusion of the water vapor. the purification action area of the strong oxidizing substance is increased.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a photocatalyst purification device, an air purifier and an air purification method. Background technique [0002] Photocatalyst purification technology is to attach titanium dioxide to the frame of the filter, generate hydroxyl radicals under the action of light, and use its strong oxidizing property to achieve air purification. Hydroxyl radicals produced during the purification process of existing photocatalyst air purification devices usually adhere to the surface of the filter screen, so that the purification effect can only be performed when the air passes through the filter screen and contacts with it, and the purification efficiency is low. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that hydroxyl radicals are attached to the surface of the filter screen and...
