Product Details

Biochar production equipment of continuous carbonization furnace for sawdust

continuous carbonization furnace intorduction:

Continuous carbonization furnace Working condition:
Moisture content no more than 15%

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.

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.

Rice husk after carbonization:

continuous carbonization furnace consists of feeding system, carbonization systems (hosts and coal discharging equipment),

purification systems, condensate systems, heating systems (gasifier),etc.

Working principle of continuous carbonization furnace :

1.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.

2.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.

3.By using flammable gas produced during carbonization, heat source recycling(close gasfier ).

4.Carbon powder cooled by carbon-discharging machine, discharged from bottom, then send to warehouse.During carbonization, by using condenser for recycling.

How to use continuous carbonization furnace ?

How to start carbonization furnace?

1.Circulating pump open

2.Host open

3.Top feeder open

4.Middle feeder open

5.Carbon discharging open

6.Open gasfier butterfly valve and outdoor exhaust valve(host pipe butterfly valve, adjustable-temperature burner butterfly valve,

host burner butterfly valve are closed)

7.Open fan, start gasfier

8.1-2 minutes later, open temperature-controlling burner valve, burner begin to work,close exhaust valve.when burner work

normally, open host burner valves, ignite the burner groups, close temperature-controlling burner valve.

9.According to different materials, when reached the required temperature for carbonization, carbonization furnace feeder begin to work, at same time, open carbonization furnace valve a little gap(recycling flammable gas in pipeline), open carbonization furnace valve step by step, close gasifier valve step by step, when gas can meet self demand, close gasifier valve.When temperature is too high, ignite temperature controlling burner, close fan to decrease temperature.

How to close continuous carbonization furnace ?

1.Close feeder( make sure no materials left)

2.Close fan

3.Close top feeder

4.Close middle feeder

5.Close carbon-discharging equipment

6.When temperature fall to 300℃,close host

7.Close pump

8.Stop power supply

9.Sealing top of gasifier and discharging gate of gasfier

10.Carbon powder storage( make sure safe, avoid fire)

Advantages of continuous 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 continuous carbonization furnace finial product:

Industrial areas:

metallurgy, suitable for the production of high quality steel.

Chemical

Medicine;

Cosmetics;

environmental protection.

The agricultural sector:

Increasing soil temperature, promote seed germination.

Keep the soil moisture.
