process for operating a sieve disc filter

摘要

Patent and Process Summary: "Method and device for operating a sieve disc filter". A process and apparatus for operating a highly viscous fusing sieve disc filter having pressures 1000 kpa (10 bar) and temperatures 90 ° C, whereby a sieve disc (1) is rotatably actuated gradually and sieve engaging elements (2) arranged on the sieve disc (1) are successively requested by a cleaning agent stream generated by a cleaning agent drive (9), must be optimized such that less cleaning agent wasted, better cleaning of the sieve fittings and energy savings are ensured. The invention proposes that the backwash cleaning occurs in the backwash cleaning station during the rotation of the sieve disc (1), whereby by means of a control or regulation device (7) associated with the activation of cleaning agent (9) to amount of cleaning agent and / or cleaning agent pressure and / or cleaning agent flow rate are adjusted depending on the time course of sieve disc rotation (1) and / or depending on a differential pressure the sieve insert (2) in the melt channel (4) and the active opening of the slit nozzle is smaller in normal to radial than the sieve disc (1) path traversed during one step drive
