Abstract: Due to the losing efficacy of the dust-cleaning at the top of the cartridge filters and the overlarge pressure at the bottom, this paper proposes to interfere the dust-cleaning fluid flow in the cartridge filters with gas diffusers based on porous media. The influence of the inlet-pressure and the diffusers based on porous media on these characteristics is simulated. Results are as follows. At the same inlet-pressure of the nozzles, the dust-cleaning performance shows the best when the porosity of the porous media is 0.87. At the same porosity of the porous media, the dust-cleaning performance shows the best when the inlet-pressure of the nozzles is 0.5MPa.
