Factory Exhaust Gas Collection Environmental Protection System

Collect workshop dust, cooking fumes, VOC exhaust gases, and odors in a centralized manner, then convey them uniformly to purification equipment for treatment, ensuring that emissions are neither dispersed nor released without meeting regulatory standards. The complete system comprises: collection hoods, ventilation ducts, airflow control valves, a main induced draft fan, a rain‑proof wind cap/check valve, a pre‑treatment section, and an exhaust stack. The process flow is as follows: workshop exhaust → collection by hoods → ductwork convergence → fan-induced draft → pre‑treatment → RTO/RCO purification → stack discharge.

    Factory exhaust gas collection system

     

    I. Function

     
    The workshop Dust, cooking fumes, VOC emissions, and odors Collect and consolidate, then convey uniformly to the purification equipment for treatment. Prevent exhaust gases from drifting freely and ensure compliant collection. 。
     

    II. Complete Set Composition

     
    1. Fume hood (Source inhalation)
     
    1. Workstation hoods, top-suction hoods, side-suction hoods, and enclosed fume cabinets capture exhaust gases at close range.
    2. Ventilation duct (Exhaust gas conveyance)
     
    1. Galvanized ductwork / spiral ductwork, collecting and conveying exhaust gases.
    2. Airflow control valve
     
    1. Adjust the suction level at each point to ensure balanced exhaust ventilation.
    2. Main induced draft fan (Power Core)
     
    1. Provides negative-pressure suction to extract exhaust gases from the entire pipeline.
    2. Rainproof Hood / Check Valve
     
    1. Anti-backflow, rainproof, and no air return when the unit is off.
    2. Preprocessing Section
     
    1. Dust removal, oil removal, and cooling to protect the downstream RTO/RCO.
    2. Exhaust chimney
     
    1. After thorough treatment, emissions are discharged in compliance with high-altitude standards.

    III. Workflow

     
    Workshop exhaust gases → Collection by hoods → Ductwork convergence → Fan-induced draft → Pre-treatment → RTO/RCO purification → Chimney emissions
     

    IV. Common Collection Methods

     
    1. Local collection : Direct suction at the workstation—most cost-effective and delivers the best results.
    2. Overall sealed collection : Whole-workshop enclosed exhaust ventilation, suitable for diffuse waste gases.
    3. Closed-gas collection on the production line : Fully enclosed collection for the drying line and the spraying line
     

    5. Pair with the complete workflow of your previous equipment.

     
    Exhaust gas collection system → High-voltage electrostatic oil-fume removal → RCO catalytic oxidation / RTO incinerator → Emission compliance
     

    VI. Key Takeaways

     
    • Collect Sufficient airflow and sufficient wind speed. , exhaust gases do not escape
    • The piping layout is straight with few bends, resulting in low resistance and energy savings.
    • Flammable and explosive waste gas treatment Explosion-proof design
    • The closer the collection point is to the purification equipment, the better the collection efficiency.
