SLUDGE SEPARATION SYSTEM AND METHOD

摘要

A system and method for cracking watery sludge, comprising first and second decant vessels for receiving and batch processing, which decant vessels include an outlet for decanting selectively separated watery residue to a drain and cracked decanted solids to a transport, with graduated heat matrix processing of the sludge at sensor-monitored temperature and dwell time for cracking the sludge, and a programmable controller responsive to temperature and level sensors for adjusting the heat media communicated through the heat matrix and for determining completion of a watery sludge cracking process.

1. A sludge separation system for cracking watery sludge, comprising:
a source of sludge; at least one decant vessel comprising:
a holding tank,a sludge inflow intermediate opposing top and bottom ends of the holding tank, for communicating sludge from the source into the holding tank,a discharge in the bottom end and communicating selectively with a decanted liquids discharge and a decanted solids discharge,a heat matrix disposed within the holding tank and having a graduated heat transfer ranging from a first heat transfer capacity at a lower end to a second heat transfer capacity at an upper end, the first heat transfer capacity greater than the second heat transfer capacity; a supply of a heat media for communicating through the heat matrix for processing the sludge to form separated decanted liquid and decanted solids; a temperature sensor for monitoring a process temperature; a solids sensor for monitoring a flow of decanted solids from the decant vessel; and a programmable controller responsive to the temperature sensor for adjusting the heat media communicated through the heat matrix and responsive to the solids sensor for determining the flow of the decanted solids following completion of a watery sludge cracking process.
