Gas Dedusting

How It Works

Gas dedusting systems clean dust-laden air or gas streams by capturing particulate matter using mechanical, electrical, or fabric-based separation techniques, ensuring the treated gas meets regulatory and workplace safety criteria.

1-Dust-laden Gas Entry

Particulate-contaminated exhaust gas enters the dedusting system from sources such as boilers, furnaces, kilns or other industrial processes.

2-Particulate Separation

Dust particles are separated from the gas stream using one or more dedusting technologies:
Electrostatic Precipitators (ESP) use high-voltage electrostatic fields to charge and collect particles on plates.
Bag Filters capture particles on filter fabrics and periodically clean the media with reverse pulses of air.
Cyclone and Wet Scrubbers use centrifugal forces or liquid sprays to remove larger dust and particulate matter.

3-Dust Collection & Removal

Captured dust accumulates on plates, fabric bags, or in hoppers and is periodically discharged or extracted for disposal or recycling.

4-Clean Gas Discharge

The cleaned gas, with significantly reduced particulate content, is discharged safely into the atmosphere or further treated if required.

Core System Components

AquipTec’s gas dedusting systems are configured using purpose-designed components, optimised for each technology type:

Electrostatic Precipitator (ESP)

Electrostatic precipitators apply electric charges to particles and collect them on oppositely charged plates. They deliver exceptional removal efficiencies (up to ~99.9%) with low pressure drop and are suitable for large-scale, high-temperature operations.

ESP Components Include:

• High-voltage power supply
• Ionising and collecting electrodes
• Plate rapping/vibration system
• Dust hopper collection system

Bag Filters (Fabric Filters)

Bag filters capture dust on woven or felted fabric media as gas passes through. Periodic pulse cleaning dislodges dust into a hopper for collection. These systems can achieve >99% particulate removal even for very fine particles.

Bag Filter Components:

• Filter bags/cartridges and cages
• Pulse-jet cleaning air system
• Dust hoppers and discharge valves
• Fans and ductwork

Cyclone & Wet Scrubber Options

Cyclone separators and wet scrubbers are often integrated upstream or downstream to handle larger particulates or combined dust and gas pollutants. Wet scrubbers use liquid sprays to capture dust and pollutants.

Supporting Components:

• Cyclone separators
• Liquid spray nozzles and recirculation systems
• Fans, dampers, and control systems

Frequently Asked Questions (FAQ)

What is a dedusting system?

A dedusting system is engineered to remove dust and particulate matter from industrial exhaust gas or air streams before they are released, improving air quality and compliance.

An ESP charges particles in a gas stream so they attach to oppositely charged plates, then periodically dislodges the dust for collection.

ESPs use electrostatic forces to collect dust (excellent for high temperature and fine particles), while bag filters use fabric media to mechanically trap dust.

Yes — dedusting solutions can be custom engineered to integrate with existing combustion or process exhaust systems.

Yes — wet scrubbers can capture dust and other gaseous pollutants by liquid spraying and are versatile for combined emissions control.
