Air purification device

Abstract

The invention discloses an air purification device which comprises active titanium dioxide powder (9), wherein the active titanium dioxide powder (9) is loaded in a transparent straight pipe (81) of a photocatalytic pipe (8); two ends of the transparent straight pipe (81) are closed by breathable films (84), so that air is allowed to pass through the films, but the active titanium dioxide powder (9) cannot pass through the films; a flow guide plate (82) is fixed in the transparent straight pipe (81); clearances are reserved between two ends of the flow guide plate (82) and two ends of the transparent straight pipe (81); one end of the transparent straight pipe (81) is connected with one end of an elbow (83); the other end of the elbow (83) is a half-blowing connection end (86); an inclined guide plate (85) is fixed in the elbow (83) at this end; one end of the inclined guide plate (85) is fixed on the elbow (83), and the other end of the inclined guide plate (85) points to the middle part of the half-blowing connection end (86); the air purification device further comprises an ultraviolet lamp (7); the ultraviolet lamp (7) is arranged at the upper end of the transparent straight pipe. Air is fully mixed with the active titanium dioxide powder in the transparent straight pipe, so that the reaction efficiency is improved.

Description

technical field [0001] The invention relates to an air purification device, in particular to an air purification device using titanium dioxide as a photocatalyst. Background technique [0002] Most of the existing devices that use titanium dioxide as a photocatalyst to purify the air are coated with titanium dioxide and work on some carrier. In this method, the coating process is very complicated and the cost is also very high. Such as Chinese patent (CN102861563A) A disclosed method of attaching titanium dioxide to activated carbon involves high-temperature heating, sol-gel and other processes, and in industrial production, it is difficult to control the adhesion rate, adhesion area, and adhesion site, so only It can handle fine granulated objects, but it is difficult to achieve large-area coating. Contents of the invention [0003] The purpose of the present invention is to provide an air purification device with simple structure and high purification efficiency using t...
