How To Produce Bamboo Charcoal?

Bamboo is a renewable resource. It can be transformed into high value-added bamboo charcoal through high temperature carbonization process. Bamboo has the characteristics of dense fiber and fast growth. After carbonization, bamboo charcoal has developed pores and strong adsorption properties. Therefore, bamboo charcoal is widely used in environmental protection, energy, agriculture, purification materials, food and other fields. So, how to produce bamboo charcoal? How to realize the efficient conversion of bamboo material through continuous carbonization furnace?

Continuous carbonization furnace can through the oxygen-poor environment. Convert bamboo material into high quality bamboo charcoal through high temperature carbonization in an oxygen-poor environment. The production process is as follows:

1. Pre-treatment Of Raw Materials

Bamboo is first cut into 2cm pieces by crusher. The moisture content of the bamboo material is reduced to less than 15% in a drum dryer to ensure the uniformity of carbonization. This ensures the uniformity of the subsequent carbonization. The pre-treatment process is required for many kinds of bamboo materials, such as moso bamboo and nan bamboo.

2. High-temperature Carbonization Pyrolysis

The bamboo chips are conveyed into the continuous carbonization furnace. Under the oxygen-poor environment of 400-600℃. The lignin, cellulose and other organic components in the bamboo material will be decomposed quickly. The volatile components (bamboo vinegar liquid, combustible gas) are separated from the solid carbon. Carbonization furnace through the precise temperature control system. Avoid excessive oxidation of bamboo charcoal and guarantee carbon content greater than 85%.

3. Combustible Gas Recycling

The combustible gas produced after pyrolysis is purified by flue gas purification device. The combustible gas goes back to the combustion chamber as auxiliary fuel through the pipeline again. Reduce the consumption of external energy. Secondly, the waste heat can also be used for drying raw materials. The utilization rate of heat energy is increased by more than 30%.

4. Charcoal Discharge and Cooling

The bamboo charcoal after carbonization in the continuous carbonization furnace is rapidly cooled down again by the water cooling system. The bamboo charcoal is then cooled down quickly by water cooling system and discharged through discharging device for automatic collection. The finished bamboo charcoal can be directly used for activated carbon processing or fuel production.
 

In the process of producing bamboo charcoal, it should be noted that: depending on the type of raw bamboo material, moisture content, bamboo growing time, production process, etc. will directly affect the final bamboo charcoal yield. Therefore, in order to obtain a higher charcoal yield, we need to consider the comprehensive factors . And take effective measures to optimize. By selecting high quality raw materials, reducing the moisture content, and adopting advanced technology, etc., we can improve the yield and quality of bamboo charcoal. So as to improve the yield and quality of bamboo charcoal. To meet the market demand.
