Definition

1. Noun:
   • A device that removes dust particles or other fine particulate matter from a flowing gas (like air or industrial exhaust) using the principle of electrostatic precipitation. It works by imparting an electrical charge to the particles and then attracting them to a collection plate with an opposite charge.

Examples of Usage

• Noun:
  • The factory installed an electrostatic precipitator to reduce its emissions and comply with environmental regulations.
  • The efficiency of an electrostatic precipitator in capturing fly ash from coal combustion is very high.

Advanced Usage

• "to be fitted with an electrostatic precipitator": to have this device installed as part of a system.
  • The new power plant's smokestacks are fitted with advanced electrostatic precipitators.
• "the performance of an electrostatic precipitator": referring to how effectively the device operates.
  • The performance of the electrostatic precipitator depends on factors like particle size and gas temperature.

Variants and Related Words

• Electrostatic precipitation (n): The process or method of removing particles using electrostatic forces. This is the principle on which the device operates.
  • Electrostatic precipitation is a common air pollution control technology.
• ESP (n): A common abbreviation for "electrostatic precipitator."
  • The ESP needs maintenance to function correctly.

Synonyms

• Dust collector: A general term for equipment that removes particulate matter.
• Particulate scrubber: Another type of air pollution control device, though it often uses a different principle (like liquid sprays).

Related Phrases

• Precipitator plate / collection plate (n): The charged surface within the device where particles accumulate.
  • Workers must regularly clean the precipitator plates to maintain efficiency.
• Corona discharge / charging electrode (n): The component that creates the ionized field to charge the particles.
  • A strong corona discharge is essential for effective particle charging in the electrostatic precipitator.
