Description

TECHNICAL FIELD

[0001] The utility model relates to the field of photocatalysis technology, specifically, relate to a kind of photocatalytic assembly. BACKGROUND

[0002] The reaction mechanism of photocatalysis technology is that photocatalyst itself adsorbs catalytic target while absorbing light energy, and generates photoelectron and hole by light excitation, and photochemical reaction occurs between target pollutants. Photocatalysis technology can almost selectively mineralize organic matter and part of inorganic matter harmful to human body and environment into CO2 and H2O and other simple inorganic matter in sufficient reaction time. Photocatalysis technology is a technology that can produce "electron-hole" pairs with strong oxidation and reduction ability by irradiating nanometer particles attached to effective medium with specific light source and reacting with oxygen in surrounding water and air. The "electron-hole" pairs can directly decompose organic pollutants and part of inorganic pollutants in air or water into harmless and odorless substances, and can destroy bacterial cell walls and kill bacteria, so as to achieve the purpose of treating wastewater and exhaust gas and sterilizing. Nanometer photocatalysis technology can be widely used in air purification, wastewater treatment, indoor formaldehyde removal, etc.

[0003] In the use process of the prior art photocatalytic assembly, for example, CN205095655U, an organic waste gas treatment photocatalytic assembly, includes a filter cylinder and a UV lamp assembly arranged inside the filter cylinder. A plurality of air inlet holes are arranged on the side wall of the filter cylinder, and the axis of the air inlet hole and the axis of the filter cylinder form an acute angle. The inner wall of the filter cylinder is provided with a photocatalyst coating, and the outer wall of the filter cylinder is provided with an inclined air inlet hole, so that the organic waste gas can enter the filter cylinder, and the UV light beam can be prevented from irradiating the outside of the filter cylinder. Although this technology improves the utilization rate of UV light to some extent, the gas near the light source in the container is more likely to produce catalytic reaction with the light source than the gas far from the light source, and the light beam cannot uniformly act on the gas, resulting in low overall catalytic efficiency and poor effect.
