coconut shells charcoal making machine working principle
Biomass two-layer continuous drum carbonization machine is a professional equipment for continuous high-temperature heating and carbonization of biomass under anaerobic and oxygen-poor conditions. It consists of two-layer carbonization machine, preheating wood powder burner (or gasifier, natural gas combustion Device), combustible gas purification device, external heating furnace of carbonization machine, feeding conveyor, cooling carbon discharge machine and control, etc., adopts a two-layer drum structure model. Biomass is conveyed by the conveyor into the inner drum, and the waste heat in the furnace is used to dry the material, preheated to 200-250°C, and enters the outer drum for high-temperature carbonization. The end of the outer drum is equipped with a combustible gas recovery pipeline, which is fully utilized in Carbon monoxide, methane, ethane and other combustible gases produced during the carbonization process are separated from wood tar, wood acid liquid, water and ash by the flue gas purification system to obtain pure combustible gases, which are sent to the external heating furnace of the carbonization machine by wind for full combustion , to heat the carbonization machine to achieve reciprocating cycle heating carbonization and continuous production. The carbonization temperature is generally controlled at /700-800°C. The carbonization product is discharged through the water-cooled carbonization machine, and the carbonization is ignited by the preheating wood powder burner (or gasification furnace , natural gas burner) to supply heat.
The biomass two-layer continuous drum carbonization machine is used to process coconut shells, walnut shells, apricot shells, hemp stalks, sawdust, sawdust, rice husks, bamboo, eucalyptus, olive pomace, bagasse, coffee grounds, palm shells, peanut shells, sunflower seeds, etc. Special carbonization equipment for dry distillation and anaerobic carbonization of small carbon-containing woody materials such as shells under high temperature conditions in the carbonization machine.
