Photocatalytic air purification device based on dispersive optical fiber

Abstract

The invention discloses a photocatalytic air purification device based on diffused optical fibers, which comprises a filter unit and a photocatalytic unit, wherein the filter unit is a cylindrical one of which the radial cross section is shaped like a ring; the upper end and the lower end of the filter unit are respectively connected with a top end cover and a bottom end cover; the center of the top end cover is provided with an air outlet; top end mounting holes are uniformly arranged in the circumference of the air outlet; bottom end mounting holes are uniformly arranged in the bottom end cover; the photocatalytic unit is a fibrous catalytic unit; and one end of the photocatalytic unit is fixedly connected with the top end mounting holes, and the other end is fixedly connected with the bottom end mounting holes. According to the technical scheme of the invention, 360-degree lateral air intake is adopted, so that the secondary pollution influence caused by byproducts of photocatalytic reaction can be effectively decreased; and titanium dioxide is simultaneously loaded on surfaces of HEPA (high efficiency particulate air) and activated carbon fibers, thereby increasing the ultraviolet utilization ratio and effectively improving the air purification efficiency. Thus, the photocatalytic air purification device is applicable to closed, flammable and explosive environments such as aircrafts, subways, trains, factories and the like.

Description

AI Technical Summary

Problems solved by technology

Most of the existing photocatalytic reactors use ultraviolet lamps as the direct light source, and direct contact between electricity and heat and the working environment is inevitable. It is mainly aimed at indoor air and cannot be used in closed, flammable and explosive environments such as airplanes, subways, trains, and factories. environment, and cannot solve the problems of low catalytic efficiency and secondary pollution in the photocatalytic process
