摘要： Process and apparatus is disclosed for providing a chemical reaction between calcium oxide containing grit particles to produce calcium hydroxide and heat, capturing the heat of hydration and using it to preheat water initially at ambient temperature, to rise to an elevated temperature to increase the amount of lime present in the water to a supersaturated lime suspension level, with the chemical reaction running to completion, followed by cooling. Heat from a water jacket may be used to raise the temperature in the lime slaker.

A process and apparatus is also provided for dissolving scale on internal surfaces of a lime slaker, a lime aging tank, grit separation device and piping and dosing sub-systems, by adding acid into the system with rinse water. A pressurized delivery system that is substantially closed to atmosphere delivers treating dosing under sufficient pressure conditions to maintain a relatively constant back pressure, by means of valving.

摘要： A method and apparatus is provided for treating water with already-slaked lime to arrive at a lime slurry that is in a solution or suspension, and delivering the thus treated water to a separating device which separates grit particles therefrom, to recover a high quality lime/water solution or suspension. An automated system controls the addition of lime and water to a lime mixing vessel.
An acid wash system is provided which comprises an automated method and apparatus for removing scale buildup, for delivering an acid wash solution to the lime mixing vessel, the lime slurry holding tank and/or the delivery system, or any of them, thereby dissolving the scale buildup.
