In recent years, indoor air pollution has severely affected people's health, and air purifiers have gradually become new essential household appliances. Since the filter materials used in purifiers are mostly disposable fiberglass, they need to be replaced frequently and maintenance costs are high. Additionally, these filters have high resistance and energy consumption, which all restrict the popularization and promotion of air purification technology for health. However, electrostatic adsorption materials utilize the principle of electrostatic attraction to efficiently adsorb PM2.5 particles and can be reused after blowing cleaning, making them widely applied in industry. This technology requires that the polluted air must be pre-mixed with negative ions sufficiently, and there must be a sufficient buffer distance between the negative ion generator and the adsorption material; otherwise, the electrostatic adsorption material will not work, thus enabling the technology to be reusable and widely applied in industry. A sufficient buffer distance must be maintained between the negative ion generator and the adsorption material; otherwise, the electrostatic adsorption material will not function, making it impossible for this technology to be well applied in small-scale purifiers. This project plans to study electrostatic adsorption materials using aerodynamic principles, combining computer simulation with experimental testing to develop a short-process negative ion and air pre-mixing technology. The main goal of this technology is to solve the problem of uniform mixing between point source particles and surface source gases within a short process of 1-5cm, thereby effectively addressing the dependency of electrostatic adsorption materials on the length of the mixing process. Through this project, on one hand, it is possible to replace traditional fiberglass filter materials with electrostatic materials in practical applications, reducing the cost of using air purifiers; on the other hand, this technology can also be effectively extended to the field of industrial gas treatment. For example, short-distance gas uniform mixing can effectively reduce the size of industrial gas mixing equipment, thereby reducing the manufacturing cost of the equipment and further enhancing the market promotion value of the research and development technology of this project.
