At present, activated carbon is increasingly widely applied in the field of environmental protection, and particularly coal-based activated carbon for water treatment has become one of the mainstream products of activated carbon. The coal-based activated carbon for water treatment is mainly produced by a gas activation method, and the main working procedures of the gas activation method comprise a carbonization working procedure and an activation working procedure, wherein the carbonization working procedure is actually a carbonization process of materials, namely the materials are heated under the condition of a certain temperature and air isolation so as to promote the materials to generate thermal decomposition reaction and thermal polycondensation reaction, and further promote the materials to separate out coal gas and coal tar so as to reduce the content of non-carbon elements in the materials and generate carbonaceous raw materials suitable for the subsequent activation working procedures. In the carbonization process, the carbonization temperature has a great influence on the quality and the yield of the carbonaceous material, if the carbonization temperature is too low, the mechanical strength of the carbonaceous material is lower, if the carbonization temperature is too high, ordered change of graphite microcrystals of the carbonaceous material is caused, and further, the pores among the microcrystals are reduced, so that the operation temperature of the carbonization furnace needs to be timely adjusted in the operation process of the carbonization furnace, and the quality and the yield of the carbonaceous material are ensured.

In the prior art, the adjustment of the operating temperature of the carbonization furnace mainly depends on the experience of a worker, namely the worker needs to adjust the operating power of a chimney pumping fan of the carbonization furnace through the experience accumulated in the working process so as to adjust the oxygen content in the carbonization furnace and further adjust the operating temperature of the carbonization furnace.

However, the adjustment accuracy of the adjustment mode is too low, and a worker often needs to adjust repeatedly to adjust the operation temperature of the carbonization furnace to a preset temperature in the actual adjustment process, so that the operation temperature of the carbonization furnace can generate large-range fluctuation in the adjustment process, which is very easy to cause the reduction of the quality and yield of the product. Meanwhile, in the running process of the carbonization furnace, workers need to observe the carbonization furnace through human eyes in the whole process, so that the labor intensity of the workers is overlarge.

In this embodiment, the control module 5 adjusts the smoke inlet speed of the accommodating cavity by controlling the rotation speed of the first fan 3.

In this embodiment, the control module 5 adjusts the near-air speed of the accommodating chamber by controlling the rotational speed of the second fan 4.

Optionally, the carbonization furnace 1 has a preset temperature range a, and the temperature detection device detects the temperature in the accommodating cavity after every preset time t, and the carbonization furnace system further comprises a counter, and the counter is connected with the temperature detection device. Wherein, when the detection value of the temperature detection device is smaller than or equal to the minimum value of the preset temperature range A; and/or when the detection value of the temperature detection device is greater than or equal to the maximum value of the preset temperature range A; and/or the counter counts when the control module 5 adjusts the rotational speed of the first fan 3 and/or the rotational speed of the second fan 4.

Meanwhile, the counter is more flexible and various in counting conditions due to the arrangement, so that different working conditions and use requirements can be met, and the processing flexibility of staff is improved.

In this embodiment, the preset time t is one minute.

It should be noted that the size of the preset time t is not limited to this, and can be adjusted according to the working condition and the use requirement. Alternatively, the preset time t is two minutes, or three minutes, or four minutes, or five minutes, or six minutes.

Therefore, the control module 5 can determine the time for adjusting the temperature according to the count values of the three counters, on one hand, the influence of fluctuation after temperature adjustment and hysteresis of temperature adjustment on the time for adjusting the control module 5 is greatly reduced, the temperature fluctuation range in the accommodating cavity is further reduced, and the difference rate of materials and the quality of finished products are improved; on the other hand, the automatic confirmation of the adjustment time of the control module 5 is realized, and the degree of automation of the carbonization furnace system is further improved. Meanwhile, the temperature in the accommodating cavity can be stabilized within a preset time t after the adjustment is finished, so that the influence of hysteresis of temperature adjustment is further reduced.

In this embodiment, in two adjacent detections of the temperature detection device, if the count value of the third counter is 0 and the first counter counts twice, it is determined that the detected value of the temperature detection device is not caused by temperature fluctuation, that is, it is determined that the temperature in the accommodating cavity is less than or equal to the minimum value of the preset temperature range a, and the control module 5 increases the rotation speed of the first fan 3 and/or the second fan 4 so as to increase the combustion distance degree in the accommodating cavity and ensure the temperature rise in the accommodating cavity.

It should be noted that the value of a is not limited to this, and can be adjusted according to the working condition and the use requirement. Alternatively, a is 8, or 9, or 11, or 12.
