ESP Electrostatic Precipitator 3D white-computer generated image

Dry Electrostatic Precipitator (ESP)

The ESP uses electrical forces to remove Particulate Matter (PM) from the flue gases. A high voltage source, generating a corona current, charges the PM which migrate to the collecting plate. PM are removed from the plate by a knocking action.

Fabric Filters (FF)

The Fabric Filter (or baghouses or bag filters) uses a filter media to separate Particulate Matter (PM) from the flue gases. The Particulate Matter are deposited at the surface of the fabric filter which may be made of different materials depending on the flue gas physical and chemical composition. The dust is removed periodically when cleaning the bags.

ANDRITZ SIR (Switched Integrated Rectifier) models

The SIR (Switched Integrated Rectifier) reduces the particulate emission level and improves ESP overall performance without the need of costly extensions. ANDRITZ provides a robust and reliable technology with the highest expertise and service capabilities in air pollution control. ANDRITZ now offers a wide range of its advanced high voltage power supplies for electrostatic precipitators.

Maintenance for Precipitators and Bag Filters

Proper maintenance of electrostatic precipitators and bag filters is essential to ensure optimal performance and a prolonged lifespan for these pieces of equipment.

Regular Inspection: Carry out periodic visual inspections to identify any damage or wear in the electrostatic precipitators and bag filters. Look for signs of leaks, wire breaks, cracks in insulators, and excessive wear of the bags.
Bag Cleaning: The filter bags can accumulate dust and particles over time, which reduces their efficiency. Schedule regular cleanings to remove dust buildup. You can use methods such as shaking the bags or using compressed air to remove adhered dust. If necessary, consider washing the bags with water and mild detergents.
Electrode Check: Electrostatic precipitators feature electrodes that can accumulate deposits of dust and dirt. Inspect and clean the electrodes regularly to maintain their efficiency. Make sure to follow the manufacturer's recommended procedures to avoid damaging the electrodes during cleaning.
Replacement of Damaged Bags or Electrodes: If you find damaged bags or electrodes during inspections, be sure to replace them immediately. Torn bags or broken electrodes can affect the system's performance and reduce its particle capture efficiency.
Control Systems Calibration: Electrostatic precipitators and bag filters are often equipped with control and monitoring systems. Carry out regular calibrations to ensure that these systems function correctly and provide accurate measurements.
Preventive Maintenance Program: Establish a preventive maintenance program to carry out tasks such as equipment lubrication, checking of electrical connections, inspection of bag cleaning systems, among others. This will help prevent future problems and keep the equipment in optimal condition.
