General Description
The BHS Rotary Pressure Filter is a continuously operating unit for pressure filtration, cake washing and drying for slurries up to 50% solids."
Filtration is conducted via pressure of up to 90 psig. Positive displacement washing, reflux or counter-current washing follows filtration. Multiple washing steps as well as solvent exchanges, steaming and extraction can also be accomplished. Finally, the cake is dried by blowing hot or ambient-temperature gas through the cake.
The Filter has a uniquely designed discharge system, which provides for atmospheric discharge from pressure filtration. After automatic cake discharge, the filter cloth is washed; the clean filter cloth the re-enters the feeding / filtration zone thereby continuing the process. All solvent and gas streams can be recovered separately and reused in the process to minimize their consumption. The BHS-Rotary Pressure Filter works on the principle of cake filtration and is designed for the following operating parameters:
Pressure design up to 6 bar
Cake thickness up to 185 mm
Operating temperatures up to 200°C
Filtration capacity from several kilograms/hour to
over 85 tons/hour of dry solids
Solids content up to 50% and higher by weight
Particle size distribution from 1 – 2 microns to over 200 microns
