Exhaust fans draw road tunnel air polluted with dust and soot into electrostatic precipitators, which eliminate the pollutants from incoming air and discharge clean air into the atmosphere. Vanes are installed at the corners of air passages to allow the clean air to flow smoothly down the passages and through silencers until it is released from the ventilation tower.
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.
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.
