AC Electrostatic Precipitators for Road Tunnels

Precipitator fans draw road tunnel air polluted with dust and soot through an air suction port in the side wall of a by-pass tunnel constructed off a road tunnel into electrostatic precipitators, which eliminate the pollutants from the air and blow clean air into the road tunnel through the other side wall of the by-pass tunnel.

1 AC Electrostatic Precipitator (AC ESP)

An AC electrostatic precipitator is constructed as a cubicle containing precharger and collecting section units. The dust collection efficiency of a precipitator is 90% and pressure loss is 200Pa at a processing gas velocity of 9m/s. See the attached catalog for details.

2 AC High Voltage Generation Unit

The high voltage generation unit generates high voltages, which are applied to the precharger and collecting section of an electrostatic precipitator. This unit was developed by Fuji Electric Systems especially for AC electrostatic precipitators. See the attached catalog for details.
