Detailed Description

When the device is used, a power supply and fuel gas are switched on, and cooling water is filled into the device through a feed port (1) of the carbonization chamber. After the raw materials are filled, the furnace cover is covered. Firstly, a draught fan (19) is started, then a burner (15) is started for ignition, after ignition, flame immediately enters a combustion chamber (8) from a combustion channel inlet (16) along a combustion channel (9) for combustion, the temperature of the combustion channel (9) is gradually increased, smoke generated by combustion flows to a smoke outlet (20) along the combustion channel (9) and is discharged out of the furnace for dust removal, desulfurization and purification treatment. After a period of time, the raw materials are ignited, combustible gas generated by the combustion of the raw materials is separated out through the air holes (11), enters the combustion chamber (8) through the triangular leakage pipe (10), and can be turned off after energy is provided for combustion. After the furnace temperature is normal, the temperature of each combustion chamber (8) is observed at any time, and the air intake of the oxygen supplementing holes (17) is adjusted along with the change of the temperature, so that the temperature of each combustion chamber (8) is always in the optimal state according to different requirements of process technology. When the temperature of the flame temperature adjusting device (6) is ultrahigh, the heat dissipation equipment of the cooling system (13) is automatically started to cool, and after the temperature is normal, the normal operation is recovered. After a period of time for debugging and operation, when discharging is needed, a discharging port (12) of the activation chamber is opened, the activated high-temperature activated carbon automatically falls into a cooling system (13) for cooling, and then is discharged out of the furnace by a water-cooling discharging machine (14). Meanwhile, the carbonized material in the carbonization chamber (2) falls into the activation chamber (7) through the discharge hole (4) of the carbonization chamber and the feed hole (5) of the activation chamber, so that the space vacated by the discharge of the activation chamber (7) is filled, and meanwhile, the carbonized material is added from the feed hole (1) of the carbonization chamber. The process is repeated to form a balanced and continuous production process of input and output.
