Activated Carbon Environmental Protection Box

Activated Carbon Environmental Protection Box(also commonly called Activated Carbon Adsorption Box or Activated Carbon Filter Box)is a piece of industrial air purification equipment that uses activated carbon to filter and purify waste gas.

Core Functions

Adsorbs VOCs:Effectively captures volatile organic compounds such as benzene,formaldehyde,and hydrocarbons.

Deodorization:Eliminates strong odors from printing,painting,plastics,and chemical processes.

Harmful Gas Removal:Filters toxic and irritating fumes to meet emission standards.

Working Principle

Gas Intake:Polluted air is drawn into the box via a fan.

Pre-Filtration:Larger dust particles are filtered out by preliminary filters.

Adsorption:Exhaust gas passes through a porous activated carbon layer.Harmful molecules are trapped on the carbon’s surface due to its enormous specific surface area(500–1500 m²/g).

Clean Air Discharge:Purified air is released into the atmosphere.

Typical Structure

Box Body:Made of galvanized steel,carbon steel,or stainless steel(SS304/316).

Activated Carbon Bed:Filled with granular,columnar,or honeycomb activated carbon.

Air Distribution System:Ensures even airflow across the carbon layer.

Access Doors:For easy replacement of saturated carbon.

Applications

Printing&Packaging:Ink VOCs

Automotive&Furniture Painting:Paint fumes

Chemical&Pharmaceutical:Process odors and solvents

Food&Beverage:Cooking and processing odors

Electronic Manufacturing:Cleaning agent vapors

Advantages

High Efficiency:Typically 90–90%removal rate for many pollutants.

Cost-Effective:Low initial investment and simple operation.

Versatile:Treats a wide range of organic gases and odors.

Easy Maintenance:Mainly requires periodic replacement or regeneration of activated carbon.

Common Specifications(Example)

Airflow:1,000–50,000 m³/h

Material:Carbon steel(powder coated)/Stainless steel

Pressure drop:200–400 Pa

Carbon type:Columnar(φ4mm)or honeycomb

Removal efficiency:>90%for VOCs

Notes

Temperature:Best for gases<50°C(higher temps reduce adsorption).

Humidity:High humidity(>90%)can lower efficiency.

Replacement:Activated carbon must be replaced or regenerated when saturated.
