The DU rubber belt vacuum filter is equipment that realizes solid-liquid separation with vacuum negative pressure as driving force. In the structure, its filtration section is arranged along the horizontal length and it can continuously perform filtrating, washing, blotting, and filter cloth regeneration etc. The equipment has the advantages of high filtration efficiency, large production capacity, good washing effect, low water content of the filter cake, flexible operation and low maintenance cost etc.
It can be widely used for solid-liquid separation in the fields of metallurgy, mining, chemical, papermaking, food, pharmacy and environmental protection etc. and it particularly has a good application in the flue gas desulfurization gypsum dehydration (FGD).
