Dingli horizontal dry distillation carbonization furnace is specially used for log, wood, jute stick, and other long rod-type biomass characteristics adopts horizontal structure, cart entry, and exit raw material and the advanced hot gas dry carbonization process technology, using a unique carbonization flue gas (volatile hydrogen material and tar, etc.) Back Burning Technology, make full use of the flue gas produced by the carbonization process, meet the thermal needs of the carbonization furnace itself, greatly increase the carbonization rate, the carbonization rate increased from 80% to more than 95%, and is easy to operate, safe and environmental protection, high production efficiency, can save a lot of energy, is the ideal equipment for carbonizing the long rod type biomass material. The combination mode of multiple devices, using carbonized flue gas in tandem, can reduce fuel consumption during carbonization production and improve the enterprise's benefit.
Dingli horizontal biomass dry distillation carbonization furnace is composed of carbonization liner, thermal insulation layer, furnace door, feeding car (small size not configured), combustible gas return combustion pipe, dehumidification buffer tank, burner, smoke exhaust pipe, and thermometer. Equipped with pre-burning gasifier, flue gas purification device, etc. The furnace adopts the principle of anaerobic dry distillation to remove volatile substances from biomass to achieve the purpose of carbonization of biomass. The charging and sealing furnace is to stack the biomass raw materials to be carbonized into the charging truck, push it into the carbonization furnace, seal the cover, and lock the furnace door; -250 ℃, the processing time is 4-12 hours (the specific heating time is determined according to the moisture content, density, diameter and furnace size of the raw material), and the moisture in the material and the air in the liner are discharged; oxygen-free carbonization The tube begins to emit faint yellow smoke (combustible gas), that is, carbonization begins, and the recovered combustible gas enters the furnace to ignite, adjust the air intake, and keep the temperature in the inner tank at 300-500 ° C for 2.0-3.5 hours (according to the density and diameter of the carbonized material). , the carbonization depth requirements and the size of the furnace determine the specific temperature and carbonization time). When the temperature is below 50°C, open the lid and discharge the charcoal. The total heating and carbonization time in this furnace type furnace is 5.0-15.5 hours, and 1-2 furnaces can be completed in 24 hours. The exhaust flue gas is treated by the dust collector to meet the standard emission. 3-5 carbonization furnaces are used in parallel, and the peak carbonization can be used to maximize the use of combustible gas to heat the carbonization furnace and reduce the consumption of wood fuel.
Dingli horizontal biomass dry distillation carbonization furnace consists of an inner tank, insulation, furnace door, rail car, combustible gas-burning pipe, dehumidifying buffer tank, burner, exhaust pipe, and thermometer. The gasifier and flue gas purification device are the optional machines. This furnace using anaerobic dry distillation principle to remove volatile substances in biomass material, to carbonize the biomass material, carbonization process: Feeding raw material and sealing the furnace→Preheating and drying the raw material → Anaerobic carbonization →Cooling and discharging the carbon, total four steps. Feeding raw material and sealing the furnace: use the rail car to feed the raw material into the carbonization furnace and lock the furnace door, finally sealing the furnace. Preheating and drying the raw material: use the wood or other fuel heat the raw material inside the furnace, from room temperature slowly heat up to 220-250℃, this process time is about 1.2 to 2.0 hours (the specific heating-up time mainly depends on raw material moisture content, density, diameter size, etc), discharge water inside the raw material and the air in the inner tank. Anaerobic carbonization: When the temperature inside the carbonization furnace increase to there is little yellow smoke discharged from the smoke tube ( hydrogen, oxygen and other volatile substances). it means to start the carbonization process, then we can recovery of combustible flue gas into furnace ignition, Adjust the intake combustible flue gas amount, keep the temperature in the inner tank about 300-550℃, 2.0-3.5 hours (the specific temperature and carbonization time is mainly depend on raw material moisture content, density, diameter size, and carbonization degree, etc). When it stops burning naturally inside the furnace, the carbonization is finished. Cooling and discharging the carbon: when the carbonization is finished, we need to open the cooling water valve to cool the inner tank, when the temperature inside of the inner tank reduces to below 50℃, then we can open the furnace door and discharging the carbon. The heating-up time and carbonization time of this model carbonization furnace are totals of about 5.5-9.5 hours, so it can finish 3 batches every 24 hours. The exhaust gas is discharged through the dust collector and can meet the environmental protection requirement. 3-5 sets of carbonization furnace used in parallel, peak shifting carbonization process. it can maximize the use of the combustible flue gas heating carbonization furnace each other, reduce fuel consumption.
