Abstract
The simulation test device of filtration for high temperature dusty gas was established based on rotating foam ceramic material. The influence of performance parameter of foam ceramic on collection efficiency, concentration of dust emission, dedusting precision and pressure loss were researched under room temperature condition. The results are shown as following: the smaller the aperture of foam ceramics is, the higher filter efficiency, the overall collection efficiency and filter precision are with lower emission concentration of dust and higher gas pressure loss of dedusting system; about 95% of dust particles which is one twenty-sixth more than the aperture of the filter can be filtered by foam ceramic; increasing the thickness is effective ways to improve the filter efficiency at the expense of much increasing gas filtering resistance of dedusting system; with the increasing of foam ceramic aperture-gradient, gas filtering resistance reduces remarkably at the expense of slight reduction of filter efficiency and a little increase of the concentration of dust emission.
