Title: Grady B Nichols: Innovator in Electrostatic Precipitation Technology
Introduction
Grady B Nichols is a notable inventor based in Montevallo, Alabama, recognized for his contributions to electrostatic precipitation technology. With a total of five patents to his name, Nichols has made significant advancements in gas separation apparatuses, particularly in the context of coal-fired electric power plants.
Latest Patents
One of Nichols' latest patents is a polarity reversing circuit for electrostatic precipitator systems. This innovative gas separation apparatus enhances the functionality of electrostatic precipitators and mechanical rappers by incorporating an opposite polarity refreshing power supply and a sophisticated switching arrangement. The switching components are designed to selectively disconnect the primary power supply and connect the refreshing power supply to the electrostatic precipitator. This process generates an electrical impulse in the precipitator, which is sufficient to dislodge precipitate from the collector plates. Additionally, an RC filter is included to control the impulse and minimize the burden on the refreshing power supply. The novel separation apparatus and technique are particularly effective when applied to the effluent stream from coal-fired electric power plants or similar gas streams.
