Abstract

The invention discloses a long-acting apparatus for purifying indoor air combined pollution, mainly comprising a high voltage electrostatic discharge pole, a dust collection panel, a photocatalysis panel, a ultraviolet light source and regeneration-free activated carbon fiber layer. A draught fan drives airflow into the apparatus, the high voltage electrostatic discharge pole removes particles in the airflow and generates certain content of ozone; an ultraviolet light source kills microorganism in the airflow and generates certain content of ozone, photon, hydroxyl radical free radical etc, meanwhile excites TiO2; the photocatalysis panel removes microorganism, degrades chemical pollutant; the regeneration-free activated carbon fiber layer removes ozone residual and particle unreacted pollutant in the airflow, at last clean air is discharged which implementing long-acting purification of indoor air composite pollutant. The apparatus according to the invention can be used for combined pollution air treatment in enclosed or semi-enclosed human life space.

Description

technical field [0001] The invention belongs to the technical field of indoor air treatment. The invention relates to a device for long-term purification of compound pollution in indoor air, especially a device for combined removal of compound pollution in indoor air by using static electricity-ozone-photocatalysis-maintenance-free activated carbon technology. Background technique [0002] On average, people spend more than 80% of their time indoors (closed spaces such as living rooms, offices, vehicles, shopping malls, hospitals, etc.), and with the modernization of production and lifestyles, especially the development of the information industry, people are more Most of the work and entertainment and sports activities can be carried out indoors, and the indoor activity time is even as high as more than 93%. The indoor air quality directly affects people's health. The main characteristics of indoor air pollution are: (1) The pollution components of indoor air pollution are...
