Description

Technical Field

[0001] The utility model belongs to the technical field of waste treatment, and in particular relates to a carbonization-activation integrated activated carbon preparation device for kitchen biogas residue. Background Art

[0002] At present, the treatment methods of sludge after anaerobic digestion of food waste in my country are mainly divided into three categories: incineration heat generation, aerobic composting, and feed conversion. Among them, incineration heat generation is mainly divided into coordinated incineration and independent incineration. It is the most significant way to reduce the amount of sludge treatment methods, but secondary pollution will be generated in the process. Aerobic composting is a treatment technology with a high degree of resource utilization of sludge. The sludge from anaerobic digestion of food waste can be converted into organic fertilizer matrix through aerobic composting, but the quality of sludge fertilizer is poor and there may be problems of excessive heavy metals. This makes the compost made from anaerobic digestion of food waste more difficult to sell than the compost made from other types of organic waste. Feed conversion is the conversion of sludge into feed through the digestion and reproduction ability of certain insects. Although this method solves the problem of homologous pollution, the problem of limited treatment scale is still difficult to solve.

[0003] The currently existing carbonization and activation integrated activated carbon preparation device for food digestate lacks the crushing function. The uncrushed food digestate particles are larger and have a smaller surface area, resulting in limited contact area for carbonization and activation reactions, which may reduce the reaction efficiency and the quality of the output activated carbon. The uncrushed food digestate has different particle sizes and shapes, resulting in inconsistent reaction uniformity between various parts during the carbonization and activation process, which may affect the consistency of the quality and performance of the activated carbon. Since larger food digestate particles take longer to reach the required reaction temperature and reaction degree, the processing time of the carbonization and activation process is prolonged.

[0027] Working principle:

[0028] When in use, the inlet end of the steam pipe 9 is connected to the steam generator, and the programmable controller 11 starts all the electric heating wires 602 and the temperature sensor 10. When the temperature detected by all the temperature sensors 10 reaches the minimum value of the temperature range set by the programmable controller 11, the programmable controller 11 starts the variable frequency motor 302 to operate, and the variable frequency motor 302 drives the rotating shaft 303 in the device body 1 to rotate, and the rotating shaft 303 drives the first spiral blade 304 and the second spiral blade 305 to rotate, so that the sludge-based biochar falling from the feeding pipe 401 into the crushing box 201 is output to the collection tank 8 through the operation of the first spiral blade 304 and the second spiral blade 305. In this process, on the one hand, the steam pipe connected to the second spiral blade 305 9 is used to steam-spray the sludge-based biochar; on the other hand, the temperature sensors 10 arranged in each zone respectively monitor the temperature of the materials on the first spiral blade 304 and the second spiral blade 305 in real time, and transmit the respective data to the programmable controller 11. If the data reaches the maximum value of the corresponding preset temperature range, the corresponding heating device is controlled to stop heating. If the data reaches the minimum value of the preset range of the corresponding zone, the heating device of the corresponding zone is controlled to heat. In other cases, the operating state of the heating device of the corresponding zone is kept unchanged. When all the sludge-based biochars that need to be carbonized and activated in sequence are output from the connecting pipe 7, the programmable controller 11 controls the variable frequency motor 302, all the electric heating wires 602 and the temperature sensor 10 to stop running, and the inlet end of the steam pipe 9 can be removed from the steam generator.

The crushing function can crush the food waste into small pieces and increase the surface area of ​​the material, which is helpful for the subsequent carbonization and activation process, so that the generation of activated carbon is more sufficient and uniform. The crushed food waste particles are smaller and more uniform, which increases the contact area with the carbonizing agent and the activating agent, thereby accelerating the chemical reaction rate, which can improve production efficiency and reduce processing time. The base 601 and the electric heating wire 602 contained in the heating mechanism 6 can realize the function of heating the inside of the device during use. The heating mechanism 6 can provide the required reaction temperature to ensure that the carbonization and activation processes are carried out within a suitable temperature range.
