Hot selling wood carbonizing furnace/activated carbon making machine

All kinds of materials should be carbonized first, and then the materials below 2mm which have been carbonized should be screened out, with water content < 15%. At this moment, the materials are fed into the elevator tank, enhanced into the top feed bin, and fed into the furnace by a frequency conversion feeder through the top feed bin. The previous afterheat temperature in the furnace needs to reach above 800°C for feeding. At this moment, the moderate oxygen should be put into the furnace by a draught fan, and the steam is open and the moderate steam is fed into the furnace to activate the materials. At this moment the steam needs to go through the steam. Two tons of steam should be fed into the furnace every activated carbon. At this moment the steam cannot be diffused steam, otherwise the less hour rate of the carbon is large and the efficiency and quality are not good. Materials gradually enter the carbonization preheating zone as the furnace body is turning. When the materials are heated to about 800 ℃, they enter the material activation area. When the materials' temperature rises quickly to about 900-1050 ℃ after the contact and reaction with water vapor, the time of contact between materials and water vapor is called as "activation time", which is about 25-40 minutes according to different temperature and oxygen supply, namely, the materials go forward at 6 meters per hour with the turning furnace body. When the material enters the cooling section, it enters the furnace body discharging pipe, and the temperature at this time is about 500-600 ℃ When passing the discharging pipe and gradually cooling down to 200 ℃, the material will automatically fall into another water cooling channel outside of the furnace. After about 3 minutes of oxygen-free cooling, the activated material has reached the room temperature, about 30-40 ℃. At this moment, the cooling-down material automatically falls into the early prepared packaging ton bag (0.5 ton per bag). When the bag is full, the material will be displaced by manpower pressure forklift. The furnace tail is equipped with a settling chamber which plays four roles: firstly, preheat the waste heat boiler; secondly, dust settlement; thirdly, after the furnace is stopped, the steam is not shut to prevent pipelines from being frozen in cold areas; fourthly, burn the unclean combustion gas again to reduce the black rock and make full use of the heat of the flue gas. Equip a steam waste heat boiler behind the settling chamber and utilize the high-temperature exhaust gas (about 800℃) to make the steam waste heat boiler generate steam, which is used for activating materials. Behind the boiler is equipped with an ID fan, in order to pump the high temperature exhaust in the boiler to the waste heat boiler, and the exhaust will be pumped into the pulse bag filter before being emitted up to the standard.
