The DU rubber belt filter is a equipment with vacuum and negative pressure as the driving force to achieve solid-liquid separation. In terms of structure, the filtering section is arranged along the horizontal length direction, which can continuously complete the filtering, washing, drying, filter cloth regeneration and other operations.

The equipment has the advantages of high filtration efficiency, large production capacity, good washing effect, low moisture of filter cake, flexible operation and low maintenance cost. It can be widely used in metallurgy, mining, chemical industry, paper making, food, pharmaceutical, environmental protection and other fields, especially in FGD (gypsum dehydration) in flue gas desulfurization.

Technical features of rubber belt filter:

A. Continuous processing of feeding filtration, filter cake washing, drying, unloading, filter cloth regeneration, etc.

B. The filter mother liquid and each section of cake wash liquid can be collected in sections, and the advection and counter-current washing can be realized.

C. Modular design of integral structure, flexible assembly, convenient transportation and installation.

D. DCS technology is applied in the control system to realize field and remote automatic control.

Application scope: it has been widely used in metallurgy, mining, petrochemical, chemical, coal washing, paper making, fertilizer, food, pharmaceutical, environmental protection and other fields such as solid-liquid separation, gypsum dehydration in flue gas desulfurization.
