Metallurgical Exhaust Gas Activated Carbon Adsorption Purification Tank Equipment
Dual Tank Activated Carbon Exhaust Gas Adsorption Purification Equipment is a mature environmental protection device specially designed for industrial waste gas treatment. It adopts a two-tank alternate working mode, where one tank performs gas adsorption purification while the other completes desorption and regeneration. This continuous operation design ensures uninterrupted exhaust gas treatment, effectively removing volatile organic compounds, odors, and toxic/harmful gas components from industrial flue gas.
This equipment is widely applicable to metallurgical workshops, chemical plants, coating workshops, printing factories, plastic processing facilities, and other production scenarios. It can handle various types of organic waste gas generated in industrial production. The system operates stably with high purification efficiency, low operating costs, and simple daily maintenance, helping enterprises meet local environmental emission standards while reducing environmental pollution risks.
The device uses high-quality activated carbon as the adsorption medium. Activated carbon features rich micropore structure and large specific surface area. When waste gas flows through the carbon layer, organic molecules are captured on the activated carbon surface through physical adsorption. When activated carbon reaches adsorption saturation, the system initiates desorption procedures. After desorption treatment, activated carbon restores adsorption capacity and can be reused repeatedly, significantly reducing filter material consumption.

Raw industrial exhaust gas is sent into the equipment through an induced draft fan. The waste gas first passes through a pre-treatment filter section to remove dust, oil mist, and particulate impurities, preventing blockage of activated carbon micropores. The gas then enters the adsorption tank where organic pollutants are trapped by activated carbon, and clean gas is discharged up to standard from the outlet.
When activated carbon inside one tank approaches saturation, the system automatically switches the gas path. The other spare tank takes over adsorption work while the saturated tank enters desorption regeneration stage. Hot air or steam is introduced into the tank to separate organic substances from the activated carbon surface. The separated concentrated organic gas can be recycled or sent to subsequent combustion treatment. After cooling, the regenerated activated carbon can be used for adsorption again.
The dual tank alternate structure represents the primary advantage compared to single tank carbon adsorption equipment. Single tank equipment requires production stoppage for carbon replacement or regeneration, while the dual tank type enables 24-hour continuous exhaust gas treatment, making it ideal for factories with continuous production lines.
- Continuous Operation Without Shutdown: Double tank switching design supports non-stop waste gas purification, suitable for 24-hour continuous production workshops without affecting factory production schedules.
- High Purification Efficiency: High-performance activated carbon material provides stable removal effect for most VOCs and odorous gases, ensuring consistent up-to-standard discharge.
- Low Operating Cost: Activated carbon can be regenerated and reused, reducing carbon replacement frequency. Automatic control minimizes manual intervention and labor costs.
- Safe and Reliable Operation: Equipped with temperature monitoring, over-temperature alarm, and pressure protection devices to prevent overheating risks during desorption processes.
- Simple Maintenance: Modular assembly structure facilitates convenient activated carbon loading and unloading. Core components are easily inspected and replaced.
This dual tank activated carbon exhaust gas adsorption purification equipment processes organic waste gas from multiple industries:
- Metallurgical Industry: Waste gas produced in smelting and material surface treatment processes
- Chemical Industry: Volatile organic gas generated in chemical raw material processing
- Coating and Painting Industry: Paint mist and organic solvent waste gas from spraying workshops
- Printing Industry: Ink volatile waste gas from gravure and flexo printing
- Rubber and Plastic Industry: Odor and organic gas released during plastic heating processing
- Electronics Industry: Waste gas from cleaning and surface coating processes
The complete equipment system comprises induced draft fan, pre-filter box, two adsorption tanks, desorption pipeline system, PLC electric control cabinet, temperature sensors, pressure gauges, and safety protection components.
The pre-filter box intercepts dust and oil particles to protect activated carbon. The two adsorption tanks serve as the core purification units. The electric control cabinet enables automatic gas path switching and regeneration process operation. All pipelines utilize anti-corrosion materials, adapting to corrosive industrial waste gas environments.
Before delivery, all equipment undergoes factory testing to guarantee stable performance. We provide detailed installation manuals and operation guides. Our technical team offers remote online installation guidance and can arrange on-site engineer commissioning when needed.
We provide warranty service for the main equipment body. During the warranty period, we supply free technical consultation and support for quality-related problems. After warranty expiration, we continue to provide spare parts supply and paid maintenance services. We train customer operators to master daily operations and simple troubleshooting skills.
When selecting this exhaust gas purification equipment, customers should provide key parameters: exhaust gas flow rate, gas temperature, pollutant type, inlet concentration, and workshop space limitations. Our technical team will calculate and recommend suitable models, adjusting tank volume, activated carbon filling quantity, and pipeline configuration according to actual working conditions.
We support customized sizes and materials. For corrosive waste gas conditions, we can apply anti-corrosion lining to tank bodies. For high concentration waste gas, we can match reinforced desorption systems to extend activated carbon service life.
