In recent years, indoor air quality that deeply affected people’s health cannot be ignored.
It is affected by many factors, and people have taken many measures to reduce the pollution level.
In addition to diluting by controlling pollution sources and using natural ventilation, air purifiers have become one of the choices, but the results are not satisfactory.
To improve the dust removal effect of the adsorption air purifier, we established the dynamic equation of PM2.5 concentration under different ventilation modes based on the analysis of indoor PM2.5 concentration change process, the integral and convergent operation of the equation were carried out, and the formula and main influencing factors of indoor PM2.5 concentration in steady state under different ventilation modes were obtained.
Meanwhile, the mathematical model of the internal pipeline of the purifier was established by using the Navier-Stokes equation; we selected the DPM model in the software FLUENT to simulate the deposition of particulate matter in the ventilation pipe.
The results showed that the deposition of different diameter particles in the filter tube was different.
The movement of the larger particle size (particle diameter >10 μm) was mainly affected by the influence of gravity and inertia, while the fine particles are easily deposited on the inner wall side of the elbow mainly by the turbulent diffusion.
Therefore, the angle of the elbow should be adjusted to direct the airflow so that most of the particulate matter could deposit on the filter element, reducing the particulate matter from the exhaust port and the damage to the human body in the room, which will improve the dedusting effect of the purifier.
