Air Cleaning Solution for Continuous Mesh Belt Furnace

pollutants Generated from Hot Process of Continuous Mesh Belt Furnace
When metals are heated, they react with oxygen in the air, forming metal oxides. These oxides often vaporize and then condense into fine, airborne particles known as fumes. Depending on the metal—such as iron, copper, or zinc—these fumes may contain hazardous compounds that contribute to air pollution.
Combustion Byproducts:
Many hot processing techniques rely on fuels or use flame-based tools (e.g., welding or cutting torches). Burning these fuels can produce additional pollutants, including carbon monoxide, nitrogen oxides, and volatile organic compounds (VOCs), which further degrade air quality.
Additives and Coatings:
If the metal has coatings, paints, or fluxes applied during processing, these materials may break down under high temperatures. Their degradation can release toxic chemicals and VOCs, compounding the pollution issue.
Ultrafine Particulates:
The process of heating and then rapidly cooling metals can result in the formation of ultrafine particulate matter (often PM2.5 or smaller). These particles are especially concerning because they can penetrate deep into the respiratory system and pose significant health risks.

How Kleanland ESP Clean the Exhaust from Conveyor Belt Furnace
The commonly used oil removers can be classified as: 1. Mechanical oil collection, 2. Wet oil mist collection, 3. Electrostatic oil mist precipitation, etc.
Mechanical oil mist collection is generally used to capture dust particles larger than 5μm, with a dust removal efficiency of 70% to 80%. For particles smaller than 5μm, the efficiency is lower.
Wet oil mist collection uses the forces of inertia, diffusion, and agglomeration to remove dust, but the dust removal resistance reaches 800 to 1000 Pa, making it unsuitable for handling large volumes of smoke.
Based on known smoke characteristics, mechanical and wet oil removal can be ruled out as viable oil removal methods. Electrostatic oil removal is an applicable method, as it can handle particles smaller than 5μm and large smoke volumes.
For the smoke under these conditions, which has a certain viscosity, electrostatic oil mist precipitation is easier to clean and offers a longer cleaning cycle. This method has the advantages of low energy consumption, low pressure loss, and high oil mist particle collection efficiency. Therefore, for this type of smoke, the optimal oil removal method is a water spray pre-treatment combined with electrostatic oil removal.
For these fine pollutants, the most effective filtration method is to first collect them efficiently, then cool them, and finally use high-pressure electrostatics for adsorption. The equipment used in this process is the Kleanland industrial electrostatic honeycomb field smoke purification system.

How ESP Device Collect Oil Mist from Conveyor Furnace Exhaust
This equipment removes oil smoke and fumes by using an electrostatic principle. Here’s how it works:
Charging Particles
A high-voltage electric field generates electrons from the negatively charged electrode (cathode). These electrons collide with air molecules, creating negative ions. Both electrons and ions attach to oil smoke particles, giving them an electric charge.
Capturing Particles
The charged particles are then attracted to the positively charged electrode (anode) by the electric field’s force, effectively trapping them.
Why It’s Effective
Electrons are millions of times smaller than smoke particles and densely packed in the electric field (up to 100 million per cm³), ensuring they easily collide with and charge nearly all smoke particles.
Charging happens in less than a second due to two mechanisms:
- Electric Field Charging: Smoke particles (which conduct electricity better than air) alter the path of electrical field lines. Ions moving along these lines collide with and transfer charge to the particles.
- Diffusion Charging: Random thermal motion causes ions to spread out and stick to particles through electrostatic attraction.
Key Advantages
- High Efficiency: The electric field’s force (Coulomb force) ensures even tiny, lightweight smoke particles are captured.
- Reliable Process: Charging is consistent and deliberate—not random—due to the controlled physics of electric fields.
This system is especially effective for removing fine, airborne oil smoke particles that traditional filters might miss.
