Patent number: 10112852Abstract: 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 the atmosphere delivers treating doses of slaked lime slurry under sufficient pressure conditions to maintain a relatively constant back pressure, by means of valving.Type: GrantFiled: May 10, 2017Date of Patent: October 30, 2018Assignee: RDP Technologies, Inc.Inventors: Richard W.

Publication number: 20130129605Abstract: A lime slaking process is provided, whereby lime is delivered from a silo into a slaking vessel, and water is likewise delivered from one or more sources, into the slaking vessel, such that unreacted lime will go through a hydration process in an exothermic reaction, and wherein the temperature of the lime being slaked in the slaking vessel is monitored and controlled via a computer that responds to the monitored temperature of lime being slaked, to add additional water and/or lime, as desired. The delivery of lime from a lime silo to the slaking vessel is via a volumetric feeding apparatus. Following the slaking process, the reacted lime and water, in the form of a slurry may be delivered to an aging tank, and subsequently to a gravity operated grit classifier. Water from the slurry may be drawn off for use at one or more dosing stations.Type: ApplicationFiled: November 22, 2011Publication date: May 23, 2013Applicant: RDP TECHNOLOGIES, INC.Inventors: Richard W.
