Problems solved by technology

[0003] The production of charcoal consumes a lot of wood resources, and more than 5 tons of fresh wood can produce 1 ton of charcoal. Due to the protection of forest resources by the country, the raw materials for charcoal production are constantly decreasing; neighboring countries such as Myanmar and Laos are more concerned about wood and its products. The control is getting stricter, and the quantity of charcoal imports is also decreasing. In addition, the traditional charcoal production method is very polluting. A large amount of smoke generated during the production process is discharged into the air, and wood tar and wood vinegar leak into the production site. Around, the pollution caused to the land has been difficult to eliminate for many years. With the continuous increase of environmental governance in our country, the polluting charcoal production method has been more and more strictly controlled.

Embodiment 1

[0032] 1) Pretreatment of raw materials: Cut the raw materials into 10*10cm blocks with a dicing machine, then fill them into the reaction kettle through the conveyor belt, and hoist the reaction kettle full of raw materials into the carbonization furnace with lifting equipment to prepare for carbonization; Said raw material is wood and wood leftover waste, and described wood leftover waste is the leftover waste material of wood processing factory production and the branch abandoned after felling in forest farm;

[0033] 2) Carbonization fuel preparation: Prepare fuel that can be directly burned as carbonization fuel, or dry the sawdust generated when the raw material is cut into pieces. The moisture content is dried to 18%, and it is sent into a pellet forming machine to be pressed into a biomass pellet fuel with a diameter of 8mm. A part of the biomass pellet fuel is added into a carbonization furnace as a carbonization fuel, and the rest is used as a by-product; The fuel th...
