Numerical Simulation Analysis of Composite Air Purifying Device

Abstract:

To solve the technical problems existing in air purification, a multilevel air purification device was presented. And the new device is the combination of catalytic purifying technology of low-temperature plasma, nanoscaled titania and dual-band ultraviolet. For further studies on performance of the composite purification device, the device has been numerically simulated, through CFD simulation technology, by employing gas phase turbulence model, porous medium model and stochastic particle trajectory model. Contrast and analysis was made on velocity distribution, particle motion state and the pressure distribution of the internal flow field under different wind speed. The most appropriate wind speed could provide better centrifugal effect and less pressure loss. So some rules of velocity and pressure distribution in internal device were acquired.
