Technical requirements of processing mechanism charcoal, wood chippers rods machine drying equipment

Comprehensive analysis of the mechanism of charcoal production mechanism of carbon technologies now make charcoal on charcoal technology has become a hot topic, a lot of people want to know about the entire process of charcoal, then here we come to tell you next. Charcoal burning whole process of dealing with the heat. How many calories, we can be measured by specific "temperature" Here we have the raw material, molding, carbonization, finished to analyze the relationship between carbon and temperature. First, the mechanism charcoal technology - material is dried: We want to ensure the quality of charcoal, we must do the carbon rods. In addition to great good or bad depending on the equipment, technology, should also depend on the size of the water contained in the raw material. General requirements for the raw material moisture content less than 12%, but we have more than 6%. Therefore, the first step of our work is to dry ingredients. When we first dry feedstock moisture content greater material has been placed in the open air or sun drying yard 1-2 days, allowed to surface water evaporation, to reduce the heat drying time and fuel consumption. Then, we will granularity qualified raw material into the dryer hot air drying to a moisture content of less than 12% of the dry material, drying temperature is generally about 160 ℃ -250 ℃. Second, the mechanism charcoal technology - raw rods rods is done in charcoal making machine (or system of rods) inside. Outside the molding machine has three cylindrical heating ring, which enables the temperature of the molding drum is raised to about 350 ℃. In order to ensure the density of carbon stipends big, smooth surface, no obvious cracks. We can according to the type and moisture content of the raw materials used to select the appropriate molding temperature. Its field-tested to determine the level of talent. In general, if we assume that the auger is qualified, and the raw material moisture content between 6-12%, the final temperature of the molding we can sawdust, wood sawdust, wood shavings and bamboo feedstock controlled 260-320 between ℃. Third, the mechanism charcoal technology - if we charring materials forming the final product is carbon, then we should be paid by carbonization furnace or kiln stick firing (or calcination) to qualified charcoal. Low-temperature carbonization process of carbon generally be divided into the following three temperature ranges. 1, the beginning of the drying stage from the ignition to the furnace temperature rose to 160 ℃, the moisture contained in this time stipends rely mainly on their salary plus heat and the heat generated by the burning stick evaporated. Chemical composition stipends almost unchanged. 2, charring the initial stage of this phase depends mainly on the stipends own burning heat, the furnace temperature rises to between 160-2800C. In this case, wood material a thermal decomposition reaction, the composition began to change. Wherein the composition is unstable, such as hemicellulose is decomposed to generate CO2, CO, and a small amount of acetic acid and other substances. 3, full carbonization temperature of this phase 280-400 ℃, at this stage, the wood material is rapidly thermally decompose, while generating a large amount of liquid product acetic acid, methanol and wood tar. It also produces methane, ethylene and other flammable gases, flammable gases in the combustion of these. Thermal decomposition and combustion gases generated a lot of heat, so that the furnace temperature increased. Wood materials at high temperature carbonization into carbon. To calcination pyrocarbon, in addition to the above-described three stages, we have to increase the heat, the temperature of the furnace continues to rise to above 700 ℃. Thus, the residue can be discharged in charcoal volatile substances, increase the amount of charcoal in the carbon-containing, so that the carbon graphite structure increases, conductivity is improved. From the above, we are in charcoal technique - charcoal throughout the process, all the time to deal with the heat, that is, part of the energy we need to consume in order to improve the economy of carbon value and use value. I hope to bring a reliable value of the above description will use the person concerned! To solve the charcoal supply situation. My business after years of painstaking research scientists successfully developed a sunrise Shito out mechanism charcoal equipment and put into mass production. Hengyuan charcoal equipment is agricultural waste, forest waste, industrial waste as raw material, simple operation, energy saving and environmental protection, the production of charcoal to reach the level of exports.
