Definitions

  • the sludge dehydrator of the present invention incorporates a system using indirect heat and a batch mode to obtain substantially improved performance in sludge dehydration.
  • a rotatably-mounted agitator 26 is adapted to agitate material in the inner cavity 14 when the agitator 26 rotates in a first direction and convey the material out of the inner cavity 14 when the agitator rotates in the other, second direction.
  • first direction is illustrated by arrow 28, and the other, second direction is illustrated by arrow 30.
  • the agitator 26 is mounted for rotation about the central axis 16 of the chamber 12.
  • the agitator 26 includes a tubular shaft 32 along the central axis 16 adapted to receive heated thermal fluid at a first end 34 thereof and return thermal fluid at the other, second end 36 thereof ( Figures 3,4).
  • a plurality of transverse discs 38 are fixed at substantially equally-spaced locations along the shaft 32.
  • the discs have substantially equal dimensions, with disc outer diameter dimensions "D 1 " begin substantially less than an inner diameter dimension "D 2 " of the inner cavity 14.
  • Substantial annular gaps 40 between the discs 38 and the inner chamber wall 22 are provided.
  • the rotating agitator 26 inside of the dehydration chamber is fabricated from a series of hollow discs 38 welded to a common shaft 32. These hollow discs 38 have a 40 degree wedge-shaped sector 60 cut out of them to allow the wet material being dehydrated to level out over the entire length of the chamber and to let the dry material pass between the discs when it is being discharged.
  • the agitator 26 is supported by the shaft 32 extending through bearings mounted at both ends of the dehydration chamber.
  • Thermal fluid rotary unions 118 are located at either end of the shaft 32 to allow the fluid to enter the rotating shaft. All of the discs 38 are connected by wiper tubes 50 which allow for the passage of thermal fluid from one disc 38 to the next.
  • the material storage/feed hopper 100 has a rotating wiper mechanism 124 that maintains a constant feed of material to a screw auger 126 positioned in the bottom.
  • the screw auger 126 conveys the material from the hopper 100 to the dehydration chamber 12 through a feed tube 128 attached to the sludge inlet port 108.
  • Wet Scrubber/Condenser 102 The vapors from the dehydrator 12 exit the dehydrator through a ducting 134 that has numerous water spray nozzles 136 positioned in it. This water spray helps to cool the gas stream and collect the particulate that is emitted from the dehydrator exhaust port 112 prior to entering the venturi scrubber/cyclone 138 where a higher efficiency scrubbing/cooling effect occur.
  • the material to be dried is placed into the material storage/feed hopper.
  • An automatic slide gate is located inside of the dehydration chamber at the opening of the material inlet port which opens when the unit is being filled and closes when the unit is in the dehydration or discharge mode.
  • the hopper will fill the dehydration chamber to the correct level based upon a predetermined time interval.
  • the dehydration process begins with agitator rotation in the correct direction and the heated fluid being pumped through the dehydration chamber and agitator.
  • the thermal fluid is maintained at a higher temperature.
  • the temperature of the oil is reduced to keep it from reaching the ignition point. This prevents the scorching, or burning of the material.
  • the flat sides of wiper tubes are working toward the material.
  • the material is agitated, lifted and churned continuously, exposing it to as much of the heated surface area of the agitator tubes, discs and cylinder walls as possible.
  • the angled conveyor bars move the material toward, and through, the discharge port opening and deposits it in the dry material conveyor.
  • the dry material is sent from the conveyor to a receptacle, or bag.
  • the system automatically closes the discharge port door and refills with wet material to begin the next dehydration cycle. Since the system is sealed, the exhaust from the dehydrator is virtually a pure vapor.
  • the air scrubber/condenser is designed to remove the particulate which may be entrained in the exhaust stream and condense as much of the vapor as possible back to a liquid.
