Abstract
The invention relates to a method and device for purifying air by means of a photocatalyst. The method comprises the steps that the air which needs to be purified is sent into a photocatalyst solution through a pipeline by means of an air pump, wherein the photocatalyst solution is contained in a container with an opening or holes; after the air which needs to be purified makes contact with the photocatalyst solution, due to light irradiation action, the photocatalyst in the photocatalyst solution prompts decomposition of partial harmful gas and substances, and the purified air is exhausted out of the liquid level and exhausted out of the container through the opening or holes of the container to enter the surrounding environment. Under irradiation of light, the photocatalyst in the photocatalyst solution can continuously and effectively enable the harmful gas and substances in the air to constantly make contact with the photocatalyst, therefore, decomposition of the harmful gas and substances is caused, and the concentrations of the harmful gas and substances in the air are decreased till the harmful gas and substances in the air are completely removed; meanwhile, secondary pollution cannot be caused, operation of a user is easy and convenient, the cost is low, and promotion and popularization of a photocatalyst air purification technology are promoted.
