Continuous carbonization furnace


The environmentally-friendly gasification continuous carbonization furnace is characterized in that carbonaceous wood materials such as wood chips, rice husks, peanut shells, plant straws, and bark (particles having a volume of 15 mm or less) are subjected to dry distillation and oxygen-free carbonization under high temperature conditions in the furnace. Ideal for high carbonization rates.This machine reasonably adopts the technology of recovering, purifying and circulating combustion of flammable gases such as carbon monoxide, methane and oxygen generated during the carbonization process. That is to solve the problem of environmental pollution caused by the thick smoke generated by the ordinary carbonization furnace in the carbonization project, and solve the thermal energy problem required by the equipment, fully self-sufficiency, improve the continuity and economy of the equipment, and fully utilize the surplus of agriculture and forestry Things, turning them into waste, alleviating the contradiction between the supply and demand of forestry resources in China, and contributing to the greening environment.


Continuous carbonization furnace working principle
This machine is equipped with: biomass gasifier, flue gas purifier, fan, self-matching gas burner, carbonization furnace and other equipment.This machine adopts the dry distillation carbonization method, which makes full use of the combustible gas such as carbon monoxide, methane and hydrogen generated in the carbonization process, and separates the combustible gas obtained from the wood tar and the wood acid solution through the flue gas purification system, and then passes through the self-matching gas burner. Fully burn, heat the high temperature carbonization pipe (the temperature is generally controlled at about 600 C). There are four layers of pipes inside the carbonization furnace 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.
