Baghouse Filter for Hot-Dip Galvanizing Fumes WEDONE

Efficient collection of zinc oxide dust and particulate emissions for cleaner exhaust air.

The WEDONE Baghouse Filter is designed to collect particulate emissions generated during hot-dip galvanizing operations. Contaminated air from the zinc kettle, galvanizing area or related material-handling processes is extracted and directed through filter bags, where zinc oxide dust and other solid particles are separated from the airflow.

• Designed for zinc oxide fumes, dust and particulate emissions
• High-efficiency filter bags selected for the operating conditions
• Automatic pulse-jet cleaning for continuous filtration
• Differential-pressure monitoring indicates filter condition
• Collected dust is discharged into a hopper for controlled handling
• Air volume and filtration area customized for each galvanizing line
• Modular construction simplifies transportation and installation
• Can be integrated with a fume enclosure, extraction ducting and exhaust fan
• Supports cleaner workshop air and project emission-control requirements

    Working Principle

    The Baghouse Fume Filter uses high-performance filter bags to capture dust and fumes from exhaust gas. Contaminated air passes through the filter bags, where particulate matter is trapped on the bag surface, while clean air is discharged through the fan and stack. A pulse-jet cleaning system automatically removes accumulated dust, ensuring stable filtration performance.

    Application in Hot-Dip Galvanizing

    Baghouse Fume Filters are widely used for zinc kettle exhaust, fluxing tanks, shot blasting, and material handling areas. They effectively reduce dust emissions, improve workplace air quality, and support sustainable and compliant galvanizing production.

    Frequently Asked Questions

    1
    What pollutants can the baghouse filter capture?
    The system is designed to capture solid particulate matter, including fine zinc oxide dust generated during hot-dip galvanizing. It is not intended to remove gaseous pollutants unless combined with additional treatment equipment.
    2
    How are the filter bags cleaned?
    A pulse-jet system periodically releases compressed air into the filter bags. This dislodges accumulated dust from the bag surfaces so it falls into the collection hopper while filtration continues.
    3
    How is the required filter size determined?
    The filter is sized according to the exhaust airflow, dust concentration, particle characteristics, gas temperature, required filtration velocity, operating schedule and applicable emission limits.
    4
    Can the baghouse filter connect to an existing galvanizing line?
    Yes. WEDONE can develop a retrofit solution based on the existing fume hood or enclosure, duct arrangement, available installation space, fan capacity and current dust-collection system.
    5
    What maintenance does the system require?
    Routine work includes checking filter-bag condition, differential pressure, pulse-cleaning components, compressed-air supply, hopper discharge equipment, seals and exhaust-fan operation. The maintenance interval depends on the dust load and operating schedule.
