Filtration Performance of Particle Removal from Gas with Ceramic Candle Filter

Abstract:

A gas-particle separation system was established to study the filtration performance where twelve ceramic filters were divided into four groups. Filters in the same group will be cleaned by pulse back-flow at once. The pressure distribution and variation during filtration and pulse back-flow washing in four group filter and along filter length was measured. The main pressure drop occurs across the filter porous wall. The pressure at filter cavity decreases from the close end to open end of the candle filter. The gas velocity magnitude inside the filter system during filtration process is generally relatively low inside the vessel. The velocity increases as the gas passes across the filter walls and enters the outlet of the filter tube.
