Embodiment 1
[0039] like figure 1 and figure 2 As shown in a preparation process of activated carbon
[0040] Proceed as follows:
[0041] Step one, material preparation: the mass ratio of 1: 2: 0.4 branches of wood, wood waste wood, bamboo heads are first cut sheet having a thickness of 2cm, length and width is then cut into 3cm 3cm * of a uniform block, after mixing standby;
[0042] Step two, the drying of raw materials: a step of mixing the starting material with a forklift loaded into bin, silo below the conveyor belt using the mixed raw material fed to the drying drum dried at a temperature of 80 ℃ of 2 hours, and then 20min at drying temperature of 105 ℃ conditions, to obtain a moisture content of 8% of the dried material;
[0043] Step three, carbonizing: Step II Dried raw materials feed auger tube carbide 20min preheated at conditions of a temperature of 220 deg.] C, and then carbonized at 600 ℃ 90min under conditions, respectively, the product was collected wood tar, wood gas and car...
Embodiment 2
[0049] like figure 1 and figure 2 As shown in a preparation process of activated carbon
[0050] Proceed as follows:
[0051] Step one, material preparation: the mass ratio of 1: 2: 0.6 branches of wood, wood waste wood, bamboo heads are first cut into a sheet having a thickness of 4cm, and then cut into 5cm * 3cm length and width of a uniform block, after mixing standby;
[0052] Step two, the drying of raw materials: a step of mixing the starting material with a forklift loaded into bin, silo below the conveyor belt using the mixed raw material fed to the drying drum dried at a temperature of 90 ℃ for 3 hours, then 30min at drying temperature is 110 ℃ conditions, to obtain a moisture content of 7% of the dried material;
[0053] Step three, carbonizing: Step II Dried raw materials feed auger tube carbide preheated at conditions of a temperature of 320 ℃ 30min, 120min and then carbonized at a temperature of 660 ℃ condition, wood tar product were collected, wood gas and carbon; wh...
