Coconut shell carbonization machine (carbonization furnace).

The coconut shell carbonization machine (carbonization furnace) is a device that directly processes various finely pided materials including wood fiber, such as imported nut shells and coconut shells, into carbon. The coconut shell carbonization machine (carbonization furnace) can continuously operate for 24 hours, and is smoke-free. It is dust-free, has no waste water discharge, and meets environmental protection requirements. The equipment has low labor intensity, low labor, high output, low energy consumption, durable equipment, basically no wearing parts, and low maintenance cost.

The coconut shell carbonization machine (carbonization furnace) adopts the dry distillation carbonization method, and fully utilizes the combustible gas such as carbon monoxide, methane and hydrogen generated in the carbonization process, and separates the wood tar and the wood acid liquid through the flue gas purification system to obtain a pure combustible gas. It is fully burned by a self-matching burner to heat the high-temperature carbonization pipe (the temperature is generally controlled at about 600 °C).

There are four layers of pipes inside the carbonization machine from top to bottom, the first and second layers are preheated drying pipes, the third layer is low temperature carbonization pipes, and the fourth layer is high temperature carbonization pipes. The first and second floors are provided with independent exhaust pipes to discharge water vapor. The pipes use the residual heat in the furnace to dry the materials, and the water vapor is discharged from the exhaust pipes.

The third and fourth floors are also provided with independent combustible gas recovery pipes. The carbonization pipes carbonize the materials at a high temperature to decompose flammable gases such as carbon monoxide, methane and hydrogen, and heat the pipes through the recovery pipes, the flue gas purification system and the burner combustion. The effect of reciprocating cycle heating carbonization is achieved. The initial carbonization ignition gas source is supplied by a biomass gasifier.

The carbonization temperature in the production process is about 500 °C; the highest temperature can reach 600-900 °C. According to different raw materials, the output of a single set of equipment is about 200kg/h. The output of the two sets of equipment is about 400kg/h.
