Integrated Oil Fume Purification Unit An Integrated Oil Fume Purification Unit is a comprehensive system designed to efficiently capture, filter, and purify oil fumes and airborne pollutants generated during cooking processes in commercial kitchens, industrial food processing, and other high-temperature cooking environments. This advanced system combines multiple purification technologies to ensure high removal efficiency, energy savings, and compliance with environmental regulations. Key Components and Working Principle 1. Capture and Extraction System - The unit begins with a high-efficiency hood or capture canopy positioned above cooking equipment to collect oil fumes at the source. - A powerful centrifugal fan creates negative pressure to ensure fumes are effectively drawn into the system. 2. Mechanical Filtration (Pre-treatment) - The first stage typically involves mesh filters or baffle filters to remove large grease particles, preventing clogging in subsequent stages. - These filters are often removable and washable for easy maintenance. 3. Electrostatic Precipitation (ESP) or High-Efficiency Purification - The core purification stage employs electrostatic precipitation, where charged plates ionize and capture fine oil droplets and particulate matter. - Alternatively, some systems use high-efficiency centrifugal separation to further remove microscopic grease particles. 4. Activated Carbon or UV Photocatalytic Oxidation (Optional) - For odor control, activated carbon filters absorb volatile organic compounds (VOCs) and cooking odors. - Advanced systems may integrate UV photocatalytic oxidation to break down harmful gases into harmless substances. 5. Exhaust Emission - Purified air is discharged outdoors or recirculated indoors, meeting air quality standards. Advantages - High Efficiency: Removes over 90% of grease particles and odors. - Energy-Saving: Optimized airflow design reduces power consumption. - Low Maintenance: Washable filters and self-cleaning mechanisms minimize upkeep. - Environmental Compliance: Meets strict emission regulations for commercial kitchens. - Compact Design: Modular structure allows flexible installation in various kitchen layouts. Applications - Restaurants, Hotels, and Canteens - Food Processing Plants - Industrial Kitchens and Cafeterias By integrating multiple purification stages, this system ensures a cleaner, safer, and more sustainable kitchen environment while reducing fire hazards associated with grease buildup in exhaust ducts.
