【 摘 要 】

A new type of wall absorbing haze automatically was presented based on industrial architecture. The purification efficiency of wall absorbing haze automatically was simulated and analyzed by Fluent. A particle trajectory analysis model based on Lagrange method was established. RNG k- turbulence eddy viscosity model was used to analyzing air flow. The momentum and turbulence equations were dispersed by the two order upwind scheme. SIMPLE algorithm was used to calculate the coupling solution of pressure and velocity. The variation of particle concentration and air pressure in wall absorbing haze automatically were simulated. The results show that the concentration change of particles in wall absorbing haze automatically is mainly affected by the adsorption of the adsorbents. The resistance that wall absorbing haze automatically acts on the air is affected by the change of air pressure. And then it affects the volume of induced ventilation of the wall. So, it has an important effect on the effect of air purification of wall absorbing haze automatically.
