LED optical fiber photocatalyst device with large-area sterilization and dirty removal capacities

Abstract

The invention provides an LED optical fiber photocatalyst device with large-area sterilization and dirty removal capacities, which comprises light-emitting diodes, optical fiber couplers and a side light-emitting optical fiber, wherein a photocatalyst material layer is wrapped on the surface of the outer edge of the light-emitting optical fiber, two end parts of the side light-emitting optical fiber are respectively connected with the optical fiber couplers, and the light-emitting diode is arranged in each optical fiber coupler. The device can be used independently or be matched with an air purifier, an industrial waste water processor and a lake organic waste water processor for use, thereby carrying out high-efficient treatment on viruses, bacteria and indoor volatile organic pollutantsin the air or a water body, and achieving the ideal environment purification effect; and the structure is compact and the use is safe.

Description

technical field [0001] The invention relates to an LED optical fiber photocatalyst device with large-area sterilization and decontamination capabilities, and belongs to the technical field of environmental protection and energy saving equipment. Background technique [0002] In today's world, due to industrialization, urban population expansion, climate change, and the application of chemical products, the environment has deteriorated sharply. At present, the air quality in my country's cities and the seven major water systems, lakes, reservoirs, and groundwater in some areas are polluted to varying degrees. Therefore, how to kill air and Harmful organic pollutants, bacteria and deodorization in water have become a growing concern. [0003] Photocatalyst purification technology is a high-tech cutting-edge purification technology that has emerged in recent years. Under light irradiation, photocatalyst can absorb light energy to excite its surface to generate electrons (e - ) ...
