1. Granular Activated Carbon Adsorption Decolorization System
► Pulse bed
•Accurately control the liquid outlet quality to the set required value / Liquid outlet quality is stable
•The liquid treated flows through the activated carbon bed from bottom to top
•Local discharge of the dirtiest activated carbon / Amount of activated carbon can be minimized / High adsorption efficiency
•Less equipment investment / Small floor area
►Fixed bed
•The inlet pressure can be controlled to a relatively low value to overcome the entire bed resistance
•Larger flow design and operational values are available
•Backwash operating is available
•Lower height/Few operators/The internal inspection of the absorber is convenient
►Comparison of adsorption efficiency between pulse bed and fixed bed
2.Granular Activated Carbon Regeneration System
►Multiple hearth furnace
Temperature Stratified Operation Control
Atmosphere Stratified Operation Control
Multiple Operation Mode
Low Power Consumption
Long Service Life
Great Airtightness
Low Heat Energy Loss
►Regeneration process
DRYING
Layer 1-2: (100-400 ℃) evaporation and drying of water in activated carbon.
BAKING
Layer 3: (400-600 ℃) evaporate and carbonize the volatile matter adsorbed in the fine pores of activated carbon.
ACTIVATION
Layer 4-6: (800-1000 ℃) blow steam to remove the carbonization in the pores of activated carbon during baking, so as to restore the activity of activated carbon.
Activating Reaction : C+H2O→CO+H2
►Advantages of multiple hearth furnace activated carbon regeneration
♦Save energy
Waste heat recovery: 1.5 t saturated steam with 5 kg pressure can be recovered for each ton of carbon regenerated
Low fuel consumption: 150 Nm3 natural gas is consumed for regenerated 1t carbon
Fuel consumption of afterburner: 150 Nm3/t carbon (natural gas 850 ℃)
♦Activated carbon water conservancy transportation system
Low abrasion consumption of activated carbon
Low risk of mechanical failure
High transmission efficiency of activated carbon (high solid-liquid ratio)
♦Activated carbon loss
We guarantee that the loss rate of activated carbon in the regeneration process is about 5-8%
►The adsorption decolorization process of granular activated carbon and multiple hearth furnace regeneration process are applied to the process flow of food industry
Newest activated carbon adsorption system OEM solution for industrial air purification and waste gas treatment systems.
