| Abstract: | The filter media of dual-layer granular bed filter for hot gas cleanup include two kinds of filter materials,one is smaller and heavy granules forming the lower layer,the other is big and light granules forming the upper layer. The combination of these two layers of the filter media provides both high filtration efficiency and high bed dust capacity.Results from the batch and industrial tests showed that the dust collection efficiencies were all over 99.99%,while the bed pressure drop was lower than 1600Pa.... |
