Before entering carbonization industry, you should learn about the carbonization process in details so that you can choose the most suitable production line for your project. Here, we will introduce the carbonization process and several application scenarios of the process, to help you understand the technology deeply.
PART1. Carbonization Process
Generally, the whole carbonization process includes 6 systems, including conveyor system, crushing system, drying system, carbonization system, exhaust gas treatment system, molding system. The principle of formulating the carbonization process is: technically advanced and economically reasonable. You can choose any of these parts to combine into your production line (click to see components of charcoal making machine here).
PART2. Application Scenarios
We will list several application scenarios of carbonization process here for your reference. The process varies according to the different combinations of condensation system, exhaust gas treatment system etc.
Example 1, standard carbonization process
Raw materials: suitable for the materials with water content less than 15%, particle size less than 20mm, and good fluidity.
Application scenario: suitable for general scenarios where the moisture content of the material itself is low, or the material has been dried to meet the feeding requirements, and there is no special requirement for the final product.
Process introduction: the material enters the charcoal making equipment from the large angle conveyor to complete the carbonization reaction, and is outputted by the double-layer water-cooled discharge screw (the owners needs to save the finished charcoal by themselves). After combustion, it is dusted by cyclone and discharged from spray tower. After dedusted by cyclone, the extra part of the combustible gas is sent to the combustion chamber. After combustion, it is concentratedly discharged to the spray tower.
Example 2, standard + condensation
Raw materials: suitable for the materials with water content less than 15%, particle size less than 20mm, and good fluidity.
Application scenario: some users who have special requirements for tar and wood vinegar.
Process introduction: the material enters the carbonization equipment from the large angle conveyor to complete the carbonization reaction, and is outputted by the double-layer water-cooled discharge screw (the owners needs to save the finished charcoal by themselves). The tar and wood vinegar are collected by the condensing system. Then the combustible gas returns to the furnace for combustion as fuel. After combustion, it is dedusted by the cyclone and discharged from the spray tower. And the excess part is sent to the combustion chamber. After combustion, it is concentratedly discharged to the spray tower.
Example 3, standard + drying
Raw materials: suitable for the materials with water content less than 45%, particle size less than 20mm, and good fluidity.
Application scenario: when the moisture content of the material is greater than 15% and less than 45%, drying needs to be added to the biomass carbonization process to dry the material and meet the feeding requirements of the back-end carbonization.
Process introduction: the material enters the dryer from the large area angle conveyor. After drying, it enters the carbonization machine to complete the carbonization reaction, and is outputted by the double-layer water-cooled discharge screw (the owners needs to save the finished charcoal by themselves). The combustible gas is dedusted by the cyclone and returned to the furnace for combustion as fuel. After combustion, it is dedusted by the cyclone and discharged from the spray tower. After the excess combustible gas is dedusted by cyclone, the excess part is sent to the combustion chamber of the exhaust combustion chamber. After combustion, it is concentratedly discharged to the spray tower.
Example 4, standard + crushing + condensation
Raw materials: suitable for the materials with moisture content less than 15%, particle size greater than 20mm, and less than 15cm.
Application scenario: this process is applicable when the particle size of the material is greater than 20mm and wood vinegar and tar need to be collected. The materials after crushing are required to be less than 20mm and greater than 5mm. After crushing, it enters the carbonization equipment to complete the carbonization.
Process introduction: the raw material enters the charcoal manufacturing machine from the large angle conveyor to complete the carbonization reaction, and is outputted by the double-layer water-cooled discharge screw (the owners needs to save the finished charcoal by themselves). After that, it is returned to the furnace for combustion as fuel, and after combustion, it is dedusted by cyclone and discharged from a spray tower. After the excess combustible gas is dusted by cyclone, the other part is sent to the combustion chamber. After burning, it will be concentratedly discharged to the spray tower.
Example 5, standard + drying + molding
Raw materials: suitable for the materials with water content more than 15%, and the particle size less than 20mm.
Application scenario: when the moisture content of the material is greater than 15% and less than 45%, and there is a demand for post-forming, this coal carbonization process is applicable. After dried and carbonized, the the material is directly used for molding.
Process introduction: the material enters the dryer from the large angle conveyor. After drying, the carbonization reaction is completed in the carbonization equipment. The ball press completes the molding. The combustible gas is dedusted by the cyclone and returned to the furnace for combustion as fuel. After combustion, it is dedusted by the cyclone and discharged from the spray tower. After the excess combustible gas is dusted by cyclone, the other part is sent to the combustion chamber. After burning, it will be concentratedly discharged to the spray tower.
Example 6, standard + double drying + crushing
Raw materials: suitable for the materials with moisture greater than 45% and particle size greater than 20mm.
Application scenario: when the moisture content of the material is greater than 45%, and the particle size is also greater than 20mm, this process is suitable. After the material is pulverized, it passes through double dryers to meet the feeding requirement for carbonization.
Process introduction: after the material is crushed, it is sent to the first dryer by a large angle conveyor, and then enters the second drying process (it should be noted that each drying process can reduce the moisture content by up to 30%), and the two drying processes are carried out. The finished material enters the carbonization equipment to complete the carbonization reaction, and is outputted by the double-layer water-cooled discharge screw (the owners needs to save the finished charcoal by themselves). After the excess combustible gas is dedusted by cyclone, part of it is sent to the hot blast stove of a dryer to provide heat source for the first drying process.
Example 7, standard + drying + molding + drying
Raw materials: suitable for the materials with water content more than 15%, and the particle size less than 20mm.
Application scenario: when the moisture content of the material is greater than 15% and less than 45%, and there is a demand for post-forming, this process is applicable. After dried and carbonized, the finished charcoal enters the molding system (ball pressing), and then enters the drying room for drying after the pressing is completed (the drying room is only used for pressing balls).
Process introduction: the material enters the dryer from the large area angle conveyor. After drying, the carbonization reaction is completed in the carbonization equipment, and the material is outputted from the double-layer water-cooled discharge screw (the owners needs to save the finished charcoal by themselves). Falling through the silo, double-shaft stirring and wheel rolling, the finished charcoal enters the ball press. After completion, it enters the drying room for drying. The combustible gas is dedusted by the cyclone and returned to the furnace for combustion as fuel. After combustion, it is dedusted by the cyclone and discharged from the spray tower. After the excess combustible gas is dusted by cyclone, the other part is sent to the combustion chamber. After burning, it will be concentratedly discharged to the spray tower.
