Abstract
Systems and methods are provided for integrated system for producing hydrated lime slurry from calcium oxide using dry calcium hydroxide as an intermediary. A hydrator is configured to receive calcium oxide and to mix the received calcium oxide with water to produce dry hydrated lime. A dry hydrated lime transportation mechanism is configured to transport dry hydrated lime from the hydrator on a continuous basis over a period of time. A storage silo is configured to receive the dry hydrated lime from the transportation mechanism. A dispensing system is configured to dispense dry hydrated lime from the storage silo into a slurry tank for combining with water to generate hydrated lime slurry.
Claims16
An integrated system for producing hydrated lime slurry from calcium oxide using dry hydrated lime as an intermediary, comprising:
- a hydrator configured to receive calcium oxide and to mix the received calcium oxide with water to produce dry hydrated lime;
- a dry hydrated lime transportation mechanism configured to transport the dry hydrated lime from the hydrator on a continuous basis over a period of time;
- a storage silo configured to receive the dry hydrated lime from the transportation mechanism;
- a dispensing system configured to dispense the dry hydrated lime from the storage silo;
- a slurry tank configured to receive the dispensed dry hydrated lime and combine the dry hydrated lime with water to generate hydrated lime slurry;
- and
- a distribution system configured to transport the hydrated lime slurry from the slurry tank to a separate process that consumes hydrated lime slurry,
- wherein the slurry tank is configured to receive the entire output of dry hydrated lime from the storage silo via the dispensing system;
- wherein the hydrator further comprises three chambers connected start to finish in a serpentine configuration, each comprising:
- horizontal rotating shafts configured to continuously mix the received calcium oxide and the water to form dry hydrated lime;
- and
- temperature transmitters configured to monitor a temperature in each chamber,
- wherein the first chamber further comprises water spray nozzles configured to supply the water for the hydrator,
- wherein the third chamber further comprises a moisture analyzer configured to monitor a moisture content of the dry hydrated lime exiting the hydrator.
