Air Pollution Control System
Our air pollution control systems, containing scrubbers control air pollution from stationary sources. It employs a liquid medium generally water, to remove particulate and gaseous contaminants from the exhaust by washing. From the application point of view, scrubbers can be classified in to 3 broad categories namely Fume Extraction Systems, Pneumatic Dust Handling Systems and Thermal Utility Systems.
Types Of Scrubbers Available
Venturi Scrubber
We at EWS design Venturi Scrubbers characterized by high energy and high collection efficiency scrubber for collection of micron size particles. Our scrubbers are relatively maintenance free and are thus preferred for all application.
The venturi scrubber utilizes a venturi to entrain contaminated gases, generally without the need for a blower in some applications. The relatively high liquid to gas ratio, liquid atomisation and open internal design provide effective scrubbing of heavily contaminated gases with minimal maintenance and virtually unlimited turndown capabilities. It can handle wide-ranging conditions while removing both toxic gases and particulate matter. Contact between the scrubbing liquid and the gas results in high gas mass transfer and/or particulate capture.
This system generally consists of a venturi, separator, sludge/ recalculation tank, pumping and dosing system.
Packed Bed Scrubbers
This scrubber can be classified as low energy and good collection and efficiency scrubber for gaseous pollutants.
Packed bed scrubbing equipment includes counter current, vertical flow packed beds and crossflow horizontal scrubbers. These units generally used to absorb gas phase contaminants from exhaust gas stream. They are generally combined with chemical treatment equipment to not only collect the gas phase contaminants but convert them into harmless substances which can be recovered or easily disposed.
The Packed Bed Scrubber System generally consists of packed bed column, pumping and dosing system and sludge disposal system.
Meeting Diverse Industrial NeedsOur air pollution control systems are suitable for a range of industries, including pharmaceuticals, food processing, chemical plants, metal manufacturing, and foundries. With custom-built dimensions and installation flexibility, they effectively extract and neutralize acid fumes, VOCs, chemical vapors, smoke, and particulate matter, ensuring compliance with regulatory norms while maintaining a safe work environment.
Advanced Filtration and Smart ControlsUtilizing activated carbon, water, or chemical-based filter media, our systems achieve industry-leading removal rates for both particulate and gaseous pollutants. The PLC-based or manual control options make operation user-friendly while enabling precise monitoring and adjustment. Integrated gas and dust sensors provide real-time performance measurement and help maintain optimal operation throughout continuous processes.
Reliability and Low MaintenanceConstructed with corrosion-resistant mild steel or stainless steel, and available in both wet and dry scrubber configurations, our pollution control systems are engineered for longevity and minimal upkeep. The efficient centrifugal or blower fans, combined with water or air cooling, ensure steady operationeven in demanding conditionsmaking them a dependable solution for industrial pollution control across India.
FAQs of Air Pollution Control System:
Q: How does this air pollution control system help manage industrial pollutants?
A: The system combines advanced filtration (with activated carbon, water, or chemical media) and customizable multi-stage scrubbing to remove acid fumes, dust, VOCs, smoke, and chemical vapors from industrial exhaust streams, achieving removal efficiencies above 99%.
Q: What installation types and control options are available?
A: You can choose between floor-mounted units, with either manual or PLC-based control panels, tailored to your site and operational preferences for efficient management.
Q: When should an industry install this system?
A: Industries handling hazardous, dusty, or odorous emissionssuch as chemical, food processing, metal, and pharmaceutical plantsshould install these systems to comply with CPCB/PCB norms and to ensure workplace safety.
Q: Where can the emission outlet and discharge be configured?
A: The emission outlet can be precisely positioned according to CPCB/PCB regulations, with flexible discharge options (top or side) to fit site-specific layouts and facilitate streamlined ventilation.
Q: What process does the system use to filter contaminants?
A: The system utilizes a combination of wet and dry scrubbing methodsincorporating water/chemical baths and activated carbon filtrationto capture and neutralize particulate matter and gaseous pollutants. Fan selection (centrifugal or blower) optimizes air flow for continuous high-efficiency processing.
Q: How is system performance monitored and maintained?
A: Real-time monitoring is achieved via integrated gas and dust sensors that track particulate and gaseous pollutant levels. The control panel (PLC/manual) enables easy adjustment, while corrosion-resistant construction ensures durability with routine maintenance.
Q: What are the main benefits of using this solution?
A: Key advantages include robust compliance with emission norms, efficient pollutant extraction (>99% efficiency), customizable build for varied site needs, low noise operation, continuous processing, and long-term reliability even in harsh industrial environments.
