Continuous Coconut Shell Carbonization Furnace This machine is equipped with:Auto-feeding Conveyor, Biomass Gasifier equipment, Dust-Removal Device, Gas cleaner system, PLC controlled and manual / automatic dual- control System, Cooling and Discharging conveyor, Carbonization Furnace and other equipments. While Carbonization of the raw material inside of the Carbonization Furnace (like coconut shell, sawdust, Palm shell, rice husk, straw, wood scrap etc.), the produced Flue Gas is recirculated in pipeline and is fed back to Heating System after purification, becomes combustible gas (carbon monoxide, methane, ethane). When the temperature reached, Carbonization furnace starting carbonizing the raw materials fed, producing the flue gases, which becomes a combustible gas after spray pour, cooling purification by the cooling purification system, to continue the carbonization Process, then Gasifier stops working or set on the minimal use. Temperature is been regulated and controlled by control system. The Feeding of the Raw Material is also regulated for the Qualified End Product. Based on the requirement of the Plant ie output of the finished Product, we can deploy a set of Furnace or Bank of furnace to yield the desired production quantum. Plant Capacities : 300 kg/hr to 2000 Kgs/hr continuous type.
Usage:widely used for engineering machinery, auto parts, fasteners, bearings, chains, metal tools and precision parts industries quenching carburizing. Features: (1)electricity-saving:adopt high tensile calcium silicate board, ceramic fiber board, heat-resistant material for high Performance. (2)operation:adopt automatic control to save manual cost. (3)quality:equipped with a variable step string fan on the top of the furnace to get uniform temperature for high quality. (4) atmosphere:adopt methanol decomposition to stabilize gas and to ensure for quality. (5) stability: cp value tolerance±0.03%(carbon potential), and temperature equally dispersed at ±5?.
Continuous pre-oxidation furnace is applied for continuous pre-oxidation treatment under controlled atmosphere of PAN based, asphalt based, viscose based carbon fiber and its felt material.
This machine is suitable for all kinds of agricultural and forestry biomass charring making. For example, wood shavings, sawdust, wood chip, rice husk, cotton stalk, crop straw, bean curd, etc Principle First, the biomass material is ignited in the gasifier. The flue gas produced by burning after spraying, cooling, purification process, it produces the pure combustible gas (carbon monoxide, methane, ethane, etc.).As the early stage of the carbonization of heat source, through the early warming of the carbonized, to feed the material when the heat reaches the special temperature. The combustible gas that carbonation process of flue gas by spraying, cooling, purification process into the burned secondary. According to this method of circulation, sufficient to achieve a self-sufficient, then achieve the effect of energy-saving. The flue gas through purification, to reach the environment production and flue gas emissions-free. Which is reached to the standards of waste gas emptying.
Biomass dry distillation carbonization furnace is Dingli new model products. The machine adopts an advanced thermal dry distillation carbonization technology. It greatly increases the carbonization rate from 85% to 98%, which is an easy operation, safe and protection environmental, and high production efficiency, which can save a lot of energy. It is the ideal equipment of coal, gas, oil, power plant. More sets of combined distillation carbonization furnace use the hoisting composite structure. It uses the hanging from the cooling method to shorten the production product date. And the efficiency of charcoal production is improved. meanwhile using a unique carbon gas (volatile hydrogen material and tar etc.) back burning technology. The flue gas produced by carbonization is sufficient usage. In addition to satisfied the demand of heat stove, to achieve energy conservation and environmental protection requirements. The excess gas can be a heat source for dryer, which can save a lot of fuel in the production. That improves the benefit of the enterprise. Carbonized without using dynamic electricity. It uses mobile production, simple and convenient operation. It is an ideal equipment for large-scale charcoal production.
Dingli biomass dry distillation carbonization furnace is composed of a carbonization furnace body, furnace cover, inner tank, material cage, combustible gas return pipe, exhaust pipe, flue gas dust removal device, tank lifting device, and thermometer. The furnace adopts the principle of anaerobic dry distillation to remove the volatile substances in the biomass and achieve the purpose of biomass carbonization. Carbonization process has four steps: charging sealing furnace - preheat drying - anaerobic carbonization - cooling carbon.
Horizontal vacuum carbonization furnace is applied for high temperature carbonization treatment of C/C, carbon fiber insulation material and high thermal conductivity graphite film.
Vertical vacuum carbonization furnace uses graphite as healing element with carbon heating environment, which max. temperature can reach above 1600°C. It is used for high temperature carbonization and cracking treatment of C/C composite material, ceramic matrix composite material and carbon fiber insulation material. And the vertical carbonization tubefurnace can also adopts all metal hot zone without carbon heating environment, which max. temperature is 1100. It is used for debinding and sinter of special materials in aerobic environment.
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 carbonization process, meet the thermal needs of carbonization furnace itself, greatly increase the carbonization rate, the carbonization rate increased from 80% to more than 95%, and easy to operate, safety 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, use carbonized flue gas in tandem, can reduce fuel consumption during carbonization production and improve the enterprise benefit.
