Emission Control System for Non-Ferrous Metal Smelting

Product Specifications

Technical details and manufacturing context for Emission Control System

Definition

The Emission Control System is a critical component of the Integrated Non-Ferrous Metal Smelting and Casting System, responsible for managing and mitigating air pollutants such as particulate matter (PM), sulfur oxides (SOx), nitrogen oxides (NOx), volatile organic compounds (VOCs), and heavy metal fumes. It ensures compliance with environmental regulations and protects worker health by treating exhaust gases before release into the atmosphere. The system typically operates by capturing emissions at source points (e.g., furnaces, casting lines), transporting them via ductwork to treatment units (such as baghouses, electrostatic precipitators, scrubbers, or catalytic converters), where pollutants are removed or neutralized, and finally exhausting cleaned gases through a stack. Key parameters include an air flow rate of 5000–20000 m³/h, filtration efficiency of 99.5–99.9% (ISO 16890), operating temperature range of -20 to 400 °C, operating pressure of 1.0–1.6 MPa, power consumption of 15–75 kW, voltage of 380–690 V AC (IEC 60038), noise level of 75–85 dB(A) (ISO 3744), dust holding capacity of 10–50 kg, filtration area of 50–500 m², weight of 1500–8000 kg, dimensions (L×W×H) of 3000×2000×2500 to 8000×4000×5000 mm, and ingress protection of IP54–IP65 (IEC 60529). The system is constructed with stainless steel. These values are reference ranges and must be verified with the manufacturer for specific models and applications. The system is designed for integration into smelting and casting lines, with interfaces for ducting, electrical supply, and control systems. Verification questions should address actual emission characteristics, site layout, and compliance requirements. Maintenance signals include increased pressure drop, reduced filtration efficiency, and abnormal noise. Failure boundaries include exceeding temperature or pressure limits, which may damage filters or components.

Working Principle

The system captures emissions at source points such as furnaces and casting lines using hoods and ducts. The captured gases are transported to treatment units where pollutants are removed or neutralized. Treatment methods may include baghouses, electrostatic precipitators, scrubbers, or catalytic converters. Finally, cleaned gases are exhausted through a stack. The system operates within specified parameters for air flow, temperature, and pressure to ensure effective capture and treatment.
