Definition
- Noun:
- An electrostatic precipitator: A "Cottrell precipitator" is a device that removes fine dust particles or other suspended matter from gases by using an electrostatic charge. It is a specific type of air pollution control technology.
Usage
- The term "Cottrell precipitator" is a technical noun used primarily in engineering, industrial, and environmental science contexts to describe a specific piece of equipment for cleaning industrial gas emissions.
- It is often used interchangeably with the more general term "electrostatic precipitator," though it specifically references the inventor, Frederick Gardner Cottrell.
Examples
- Noun:
- The factory installed a Cottrell precipitator to reduce particulate emissions from its smokestacks.
- The efficiency of the Cottrell precipitator in capturing fly ash is over 99%.
Advanced Usage
- Historical Context: The device is named after its American inventor, Frederick Gardner Cottrell, who patented the first successful electrostatic precipitator in 1907.
- Technical Operation: The process involves giving the particles in the gas stream an electrical charge and then collecting them on plates or electrodes with the opposite charge.
