Description
The environmental protection carbonization furnace adds a flue gas recovery device on the basis of the original carbonization furnace. After the flue gas is recovered, it can be dust-free and smoke-free. The recovered flue gas can be ignited like liquefied gas for heating, cooking, and drying. .There are three types of carbonization furnaces, ordinary type (can only be used to produce charcoal, and cannot collect gas); wood carbonization equipment (used to carbonize branches, wood blocks, coconut shell blocks, scraps in furniture factories, etc. This equipment can be equipped with gas The gas recovered by the furnace device is turned into gas for the carbonization furnace itself or others); carbon powder production line (a machine used to produce carbon powder, which can carbonize rice husk, sawdust and bamboo powder into carbon powder and can be processed into activated carbon).carbonization processThe carbonization process of the carbonization furnace can generally be divided into the following three temperature sections:drying stageFrom the start of ignition, until the furnace temperature rises to 160 ° C, the moisture contained in the machine rod is evaporated mainly by the external heat and the heat generated by its own combustion. The chemical composition of the mechanical rods has hardly changed.Initial stage of carbonizationThis stage mainly relies on the combustion of the rod itself to generate heat, so that the furnace temperature rises to between 160 and 280 °C. At this time, the wood material undergoes a thermal decomposition reaction, and its composition begins to change. Among them, unstable components, such as hemicellulose, are decomposed to generate CO2, CO and a small amount of acetic acid.full carbonization stageThe temperature at this stage is 300 to 650°C.During this stage, the wood material undergoes rapid thermal decomposition, and a large amount of liquid products such as acetic acid, methanol and wood tar are produced. In addition, flammable gases such as methane and ethylene are produced, and these flammable gases are burned in the furnace. Thermal decomposition and gas combustion generate a large amount of heat, which increases the furnace temperature, and the wood material is dry-distilled into charcoal at high temperature.To calcine high-temperature charcoal, in addition to the above three stages, we also need to increase the heat, so that the temperature in the furnace continues to rise to about 800 ° C ~ 1000 ° C, so that the volatile substances remaining in the charcoal can be discharged, and the charcoal content can be increased. The carbon content of carbon increases the graphite structure of carbon and enhances the conductivity.Baoyuan Machinery is a comprehensive enterprise that comprises R& D, test, manufacture, sales and service functions. We have succeeded in researching and supplying solutions with the following equipment: Drying equipment, building materials equipment, agriculture equipment and other products.
