Problems solved by technology

At present, most photocatalytic air purification devices generally adopt a honeycomb structure. This structure has the advantage of large reaction area, but it has a major disadvantage that the utilization rate of light energy is low. After ultraviolet light enters the honeycomb channel, its light intensity rapidly increases along the channel axis. attenuation, which leads to low reaction efficiency of such reactors

Embodiment Construction

[0013] please see figure 1 . 1 is a square-wave basic building unit, and the dotted lines represent two other basic building units stacked up and down with it, 2 is an ultraviolet lamp tube, and 3 is a support for the ultraviolet lamp tube. From this it can be seen that by figure 1 The three basic building units form a combined photocatalytic air purification and sterilization device composed of multiple photocatalytic air purification and sterilization components. The corresponding device is much simpler, and the utilization rate of the coated photocatalytic material is improved, and the consumption amount of the photocatalytic material is saved. As long as the above three basic building units are stacked up and down and then welded to form, the same below.

[0014] please see figure 2 . 4 is a zigzag basic building unit. The rest are the same figure 1 .

[0015] goodbye image 3 . 5 is the corrugated basic building unit, and the rest are the same figure 1 .

Abstract

The combined and superposed photocatalytic air purifying sterilizer contains photocatalytic air purifying and sterilizing element combination of several basic structure units with nano level photocatalytic material painted to the walls; ultraviolet lamp tubes with axes parallel with the air flow passage; and the support for the combination and the ultraviolet lamp tubes. The basic structure unit may have walls of wavy, square wave or sawtoothed surfaces, and may have connected fins or specially shaped air flow choking matters painted with nano level photocatalytic material. These ultraviolet lamp tubes are set inside the air passage homogeneously. The present invention has the advantages of simple production process, high light energy utilization, high air purifying efficiency, and high sterilizing effect.

Description

technical field [0001] A stacked and combined photocatalytic air purification and sterilization device belongs to the field of photocatalytic air purification devices. Background technique [0002] Nano-scale semiconductor photocatalytic materials or hybrid photocatalytic materials are referred to as nano-scale photocatalytic materials in this application document. Under the irradiation of ultraviolet light, when they contain pollutants (mainly formaldehyde and volatile organic compounds commonly and inorganic pollutants) when the air flows over its surface, the pollutants can be oxidized and decomposed into harmless CO 2 、H 2 Inorganic small molecules such as O can purify the air; at the same time, when the ultraviolet light released by the ultraviolet light source directly kills the bacteria in the air, the photocatalytic material can also capture the suspended bacteria in the air, and oxidize them through the photocatalytic reaction to achieve sterilization the goal of....
