Rotary carbonization furnace for turning biomass into biomass biochar

Rotary carbonization furnace for turning biomass into biomass biochar

Rotary carbonization furnace intorduction:

Rotary carbonization furnace working condition:
Moisture content no more than 15%

Rotary carbonization furnace Applications:All kinds of biomass material: Fruit Husk,Wood Scraps and Crop Stalks,
Fruit Husk---Rice husk,Coconut shell, Peanut shell/Groundnut shell,Sunflower seed husk/shell,Palm kernel shell,Walnut shell,etc.
Wood Scraps---Wood sawdust,Wood shavings,Wood chips,Tree branch, Bamboo scraps,Waste from beer breweries,etc.
Crop Stalks---Plants straw,Crop residues,Soybean straw,Wheat straw,Cotton straw,Corn stalks,Maize Cob/Corncob,etc.

Continuous carbonization furnace Materials requirements
Particle size is less than 15 mm, water content <15% of biomass particles can feeding into the carbonization furnace directly, such as: sawdust, rice husk, palm shell, peanut shell, bamboo shavings, etc.;When you carbonize larger raw materials (Particle size more than 15 mm), raw materials need to be crushed into less than 15mm pieces firstly; If water content is more than 15%, using dryer for drying firstly, for fully carbonized and get high quality carbon.

Working principle of Rotary carbonization furnace:

 Agricultural and forestry waste enter into gasfier, produced flammable gas send by high pressure fan into spray filter,After cooling by condenser, then gonging to burner at the bottom of carbonization equipment.
When Pipe temperature reach the demand for carbonization, materials conveyed by feeding conveyor to top feeder , top feeder carried materials into top high temperature tube for drying, by rotation tube and screw device inside tube, materials walking from one end to the other end, then middle feeder, middle high temperature pipe, bottom feeder, bottom high temperature pipe.
By using flammable gas produced during carbonization, heat source recycling(close gasfier ).
Carbon powder cooled by carbon-discharging machine, discharged from bottom, then send to warehouse.During carbonization, by using condenser for recycling wood vinegar fluid and wood tar oil.

 Hypoxia negative pressure high temperature carbonization pipeline carbonization, produced carbon monoxide, mathane, oxygen, by recycling, purification,circulating burning, solved environmental problem and heat source problem.

Rotary carbonization furnace diagram:

1.    Biomass gasifier is used for producing the smoke gas, usually use the rice husk, sawdust and agricultural waste as fuel.

2.    The smoke gas from biomass gasifier will be purified by spraying and filtering device, cooled to the proper temperature by the condensator.

3.    The thermal control nozzle is used for controlling the gas inlet, will be burned if the purified gas is too much more before operating the rotary continuous carbonization furnace.

4.    Screw conveyor(feeder) is used for evenly and quantitatively feeding the materials to the rotary continuous carbonization furnace.

5.    Burner or spray nozzle is used for gas burning to produce the heat for supplying the rotary continuous carbonization furnace.

6.    Rotary continuous carbonization furnace is used for carbonization of the input raw materials.(the input material doesn’t contact with the burning fire and achieving the heat transfer to heat the outer wall of the rotary drum)

7.    Carbon discharging device is used for cooling the output finished products and conveying by water cooling method.

Advantages of Rotary carbonization furnace:

1. High pressure fan absorb carbon monoxide, mathane, oxygen for recycling.

2. Three layers integrated.

3. Under the function of heat preservation box, carbonization goes smoothly.

4.Combined chain wheel, chain rotation with reducer and adjustable-speed motor, carbonization equipment can work continuously. Adjustable-speed motor applied to different materials, ensure carbon powder quality.

5.Groove equipped with supporting wheel, offering power for continuous carbonization.

6.Screw device ensured materials conveyed from one end to the other end, screw height and screw pitch, ensured production and space for discharging of flammable gas and steam, solved problem of congestion. (Under high temperature, materials produce wood vinegar fluid gas, wood tar oil gas and steam, if it can not discharging in time, may jammed)

7.Screw device make materials heating uniform, continuous production, high quality carbon powder.

8.Sealed box and high temperature graphite fixed in sealed slot, by snap ring and screw bolt, adjust sealing clearance.

Application of Rotary carbonization furnace finial product:
