Description

Technical Field

[0002] Activated carbon is a specially treated carbon. The organic raw material is heated in an air-tight condition to reduce the non-carbon components, and then reacts with the gas to corrode the surface to produce a well-developed microporous structure. Since the activation process is a microscopic process, that is, the surface corrosion of a large number of molecular carbides is point corrosion, the surface of the activated carbon has countless tiny pores.

[0003] At present, the existing methods for disposing industrial sludge are mainly anaerobic digestion and incineration. Although the reduction and resource utilization of sludge have been achieved to a certain extent, there are also problems such as low treatment efficiency, insufficient product utilization, large amount of incineration tail gas treatment, large amount of CO2 increase, and secondary pollution. If the method of making activated carbon from industrial sludge and straw is adopted, the mixing ratio of industrial sludge and straw cannot be controlled by the mixing device of industrial sludge and straw during operation, resulting in unstable capacity of the activated carbon finally produced.

[0024] The above scheme is adopted: by starting the motor 209, the motor 209 drives the stirring shaft 2010 to rotate, thereby driving the stirring blades 2011 inside the stirrer body 201 to fully crush and mix the dried industrial sludge, straw and other raw materials, so that they are evenly distributed in the entire preparation process, which helps to ensure that the final activated carbon has consistent physical and chemical properties and adsorption performance.

[0025] refer to Figure 1 , Figure 4 and Figure 5The carbonization feed port 402 is opened on the left side of the pyrolysis carbonization furnace 401, the carbonization furnace door 403 is movably installed in the inner cavity of the carbonization feed port 402, the air inlet pipe 404 is fixedly installed on the top of the pyrolysis carbonization furnace 401, and a second conveyor belt 5 is fixedly installed on the right side of the pyrolysis carbonization system 4, and an activation system 6 is fixedly installed on the right side of the second conveyor belt 5. The activation system 6 includes an activation furnace 601, a hopper 602, a spiral feed rod 603, a venturi tube 604, and a fan 605. The activation furnace 601 is fixedly installed on the right side of the pyrolysis carbonization system 4, the hopper 602 is fixedly installed on the top of the activation furnace 601, the spiral feed rod 603 is movably installed on the right side of the hopper 602, the venturi tube 604 is fixedly installed on the front of the activation furnace 601, and the fan 605 is fixedly installed on the end of the venturi tube 604 away from the activation furnace 601.

[0026] The above scheme is adopted: through the setting of the activation furnace 601, the biochar produced after the carbonization is completed is conveniently chemically conditioned and enters the activation furnace 601, and oxygen-containing gases such as water vapor and flue gas are used as activators to contact with the carbon at high temperature to cause redox reaction for activation, and the purpose of forming pores in the carbon particles is achieved through the gasification reaction of carbon, and the pores are further deepened and penetrated to form more small pores and micropores, thereby preparing high-quality activated carbon with developed pores and excellent adsorption performance.

[0027] Working principle:

[0028] When in use, the industrial sludge is dried in the dryer 1, and 6% to 15% of high-temperature dry material is formed after drying and transported to the stirring mechanism 2 on the right for crushing and mixing. The mixing ratio of the industrial sludge dry material and the straw can be strictly controlled by the first flow valve 202 and the second flow valve 204. The crushed mixed dry material is transported to the pyrolysis carbonization furnace 401 through the first conveyor belt 3. Under high temperature and oxygen-free conditions, the low-boiling point and volatile substances in the mixed dry material are evaporated, while the organic matter is retained in the form of solid carbon. During the cracking process, a series of reactions occur in toxic and harmful high-molecular organic substances, causing them to decompose and escape as small molecular substances, which not only solves the problem of harmful substances, Moreover, heat can be recycled, saving energy consumption. In addition, the heavy metal ions in the mixed dry materials are combined with the solidified carbon with stable chemical bonds. The heavy metal ions are transformed from the original extractable state to a stable state, and are difficult to be separated from the carbon, so that they cannot be leached into the environment and no secondary pollution is generated. The carbon material after pyrolysis and carbonization enters the activation furnace 601 from the hopper 602, and is transported to the discharge end of the activation furnace 601 along the axial direction of the activation furnace 601 under the rotation of the spiral rod 603. The purpose of forming holes in the carbon particles is achieved through the gasification reaction of the carbon, and the pores are further deepened and penetrated to form more small pores and micropores, thereby preparing high-quality activated carbon with developed pores and excellent adsorption properties.

[0029] To sum up: this activated carbon preparation device for industrial sludge-straw composite biomass, through the coordinated use of a stirring mechanism 2, a pyrolysis carbonization system 4 and an activation system 6, solves the problem that the existing industrial sludge disposal method is mainly anaerobic digestion and incineration. Although the sludge reduction treatment and resource utilization are achieved to a certain extent, there are also problems such as low treatment efficiency, insufficient product depth utilization and large incineration exhaust gas treatment volume, a large amount of CO2 increase, and secondary pollution. If the method of making activated carbon from industrial sludge and straw is adopted, the mixing ratio of industrial sludge and straw cannot be controlled by the industrial sludge and straw mixing and stirring device during operation, resulting in the problem of unstable capacity of the activated carbon finally produced.
