[0002] Activated carbon is a porous carbon-containing material with a very developed pore structure and a huge specific surface area. The surface has surface functional groups with special functions containing oxygen and other elements. It is often used as a catalyst, adsorption material and energy storage material, and is widely used in important fields such as food processing, chemical industry, medicine, and military. Activated carbon is a specially treated carbon. The organic raw materials such as fruit shells, coal, and wood are heated under air-tight conditions to reduce non-carbon components. This process is called carbonization, and then it reacts with gas, the surface is corroded, and a structure with developed micropores is produced. This process is called activation. Since the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, the surface of the activated carbon has countless tiny pores.

[0023] refer to Figure 1 , Figure 4 and Figure 5 The stirring mechanism 9 includes a motor 901, a rotating shaft 902 and stirring blades 903. The motor 901 is fixedly installed on the top of the support plate 10. One end of the rotating shaft 902 is fixedly installed on the output end of the motor 901. A plurality of stirring blades 903 are fixedly connected to the surface of the rotating shaft 902. The other end of the rotating shaft 902 is connected to the inner wall of the activation furnace 1 through a fixed block 904. A mounting hole 905 is provided on the side of the fixed block 904 close to the rotating shaft 902. A second control valve 11 is fixedly installed on the left side of the activation furnace 1. A discharge port 12 is provided at the bottom of the activation furnace 1. A sealing door 13 is movably installed in the inner cavity of the discharge port 12. A discharge trough 14 is movably installed at the bottom of the discharge port 12. A collecting tank 15 is fixedly installed on the front of the discharge trough 14.

[0024] The above scheme is adopted: by starting the motor 901 and stirring the fan blades 903, the carbonized raw materials are fully in contact with the activating agent and are evenly distributed, and then the motor 901 is turned off and the activation is allowed to stand, and the ash content of the produced activated carbon is low.

[0025] refer to Figure 1 , Figure 2 and Figure 5 An air inlet pipe 16 is fixedly installed on the left side of the carbonization furnace 2, a combustion furnace 17 is fixedly installed on the left side of the air inlet pipe 16, the combustion furnace 17 and the activation furnace 1 are connected through an air outlet pipe 18, a chimney 19 is fixedly installed on the top of the right side of the activation furnace 1, a smoke filter 20 is fixedly installed in the middle part of the chimney 19, a supporting leg 21 is fixedly installed on the bottom of the activation furnace 1, a connecting tube 3 is fixedly installed in the middle part of the activation furnace 1 and the carbonization furnace 2, and a controller 22 is fixedly installed on the back of the activation furnace 1.

[0026] The above scheme is adopted: through the setting of the air inlet pipe 16, a large amount of combustible gas generated during the carbonization process enters the combustion furnace 17, and then is ignited by the igniter to generate a large amount of water vapor. These water vapors with a large amount of heat enter the activation furnace 1 through the air outlet pipe 18 to provide heat for the activation reaction. The water vapor is filtered of harmful substances by the smoke filter 20 and then discharged through the chimney 19.

[0027] Working principle:

[0028] When in use, the staff feeds the bagasse raw material into the carbonization furnace 2 from the feed port 4 through the feed hopper 5, and carbonization occurs after high temperature and high pressure. After the carbonization is completed, the first control valve 6, the second control valve 11 and the igniter of the combustion furnace 17 are started by the controller 22, and the carbonized raw material falls into the activation furnace 1 at the bottom. A large amount of combustible gas is generated during the carbonization process. The combustible gas enters the combustion furnace 17 through the air inlet pipe 16 and is ignited to generate a large amount of water vapor. These water vapors with a large amount of heat enter the activation furnace 1 through the air outlet pipe 18 to provide heat for the activation reaction. The water vapor passes through the smoke filter 2 0 After filtering harmful substances, they are discharged through the chimney 19, the controller 22 opens the electric control water valve 8 and the motor 901, and the activator is input through the liquid inlet pipe 7. The activator flows to the surface of the carbonized raw material through the liquid inlet pipe 7. After the motor 901 is started, it drives the rotating shaft 902 to rotate, and the rotating shaft 902 drives the stirring blade 903 to rotate so that the carbonized raw material is fully in contact with the activator and evenly distributed. Then the motor 901 is turned off, and the activation is left to stand. After the activation is completed, the sealing door 13 is opened, and the generated activated carbon falls into the discharge trough 14 through the discharge port 12, and finally enters the collecting tank 15 for storage.

[0029] In summary, the activated carbon preparation device for bagasse solves the problem that the bagasse produced by the sugar mill is mainly used for boiler incineration and provided to paper mills for papermaking, and its utilization value is low through the coordinated use of the activation furnace 1 and the carbonization furnace 2.
