Class Information
Number: 96/77
Name: Gas separation: apparatus > Electric field separation apparatus (e.g., electrical precipitator, electrostatic type, etc.) > Plural diverse electric fields > Serially arranged ionizing and collecting or agglomerating fields
Description: Apparatus in which the electrode arrangement defines two electric fields, one downstream of the other in the direction of flow of the gaseous fluid mixture, the upstream field serving primarily to electrically charge particles in the gaseous fluid mixture and the downstream field serving primarily to collect or coalesce the charged particles.
