In some embodiments, terminal device 240 may be fixed and/or mobile.

Fig. 3 is an exemplary flow diagram of a dry carbonization method according to some embodiments herein. In some embodiments, the process 300 may be performed by the dry carbonation integrated system 100. As shown in fig. 3, the process 300 includes the following steps:

in step 310, the sludge input unit delivers the sludge to be treated to the drying unit.

And 320, drying the input sludge by the drying unit, and inputting the dried sludge into the carbonization unit.

In some embodiments, the drying unit may turn, agitate, and hot air heat the sludge such that the sludge is dewatered. In some embodiments, the drying unit may reduce the water content in the sludge to below 30%.

And 330, carbonizing the dried sludge by the carbonizing unit, and outputting the carbonized sludge through the carbide output unit.

In some embodiments, the carbonization unit may carbonize the sludge by heating. In some embodiments, the carbonization unit includes a plurality of carbonization sub-units, and the sludge may be sequentially transferred from the first carbonization sub-unit to the second carbonization sub-unit, from which the sludge is input to the third carbonization sub-unit … … until the desired effect is achieved, and the carbonized sludge is output through the carbide output unit.

In some embodiments, the sludge is carbonized in the carbonization unit by indirect heating, and heavy metal ions (e.g., Pb, Cd, Cr, Ni, etc.) in the sludge can be solidified in the carbide product, thereby becoming stable and environmentally friendly. Wherein, the indirect heating can mean that the sludge is subjected to dry distillation at a low oxygen and high temperature. In some embodiments, if sludge is directly incinerated in an incinerator, a large amount of toxic and harmful substances such as dioxin may be generated, and the sludge is carbonized by indirect heating in a carbonization unit, and the dioxin is completely decomposed at a high temperature (e.g., 800 ℃), so that the generation of dioxin can be effectively suppressed, and a carbonized product rich in fixed carbon is formed after carbonization, thereby greatly reducing the emission of carbon dioxide.

In some embodiments, the carbide product may be used as a soil improvement material (e.g., for horticultural soils, etc.), a deodorant, a building material (e.g., as a cement raw material), a fuel (e.g., for thermal power generation), a dehydration aid, a snow melt agent, and the like.

And 340, dedusting the gas in the drying unit through a dedusting unit.

And 350, deodorizing the dedusted gas by a deodorizing unit, and discharging the gas after reaching the standard.

In some embodiments, the heat source of at least one of the drying unit and the carbonizing unit may be provided by a heating unit. In some embodiments, the carbonization gas generated by the carbonization unit can be introduced into the heating unit to fully and effectively utilize the combustion heat of the carbonization gas, thereby saving energy.

In some embodiments, the sludge input unit may include a first moisture content detection device, the drying unit may include a second moisture content detection device and a first gas overflow amount detection device, and the carbonization unit may include a second gas overflow amount detection device.

In some embodiments, the drying unit may have a corresponding standard moisture content and a corresponding standard gas overrun, and the carbonization unit may have a corresponding standard gas overrun. In some embodiments, the carbonation unit includes a plurality of carbonation sub-units, each of which may have a respective standard gas overrun. Standard indexes such as standard water content and standard gas overflow amount can be preset.

In some embodiments, after the detection criteria meet the criteria during the processing of each cell, the next cell can be entered. For example, when the moisture content detected by the second moisture content detection device of the drying unit reaches the standard moisture content, and the gas amount detected by the first gas overflow amount detection device of the drying unit reaches the standard gas overflow amount, the sludge in the drying unit can enter the carbonization unit. For another example, the gas amount detected by the gas overflow amount detecting device of the current carbonization subunit reaches the standard gas overflow amount, and the sludge in the carbonization subunit can enter the next carbonization subunit. For another example, when the amount of gas detected by the second gas overflow amount detecting means of the carbonization unit reaches the standard gas overflow amount, the sludge in the carbonization unit can enter the carbide output unit.

In some embodiments, since the sludge per treatment may vary, the criteria may be determined in conjunction with the specific condition of the sludge. For example only, the sludge of the sludge input unit may be detected, and the standard index may be determined based on the detected data of the sludge. For example, the water content of the sludge in the sludge input unit may be 90%, and the standard water content corresponding to the drying unit may be 30%.

In some embodiments, historical production data that is qualified in production quality or meets requirements may be obtained, vectors may be constructed based on the historical production data, clustering may be performed based on the vectors, and values of the standard indicators may be determined.

For example only, for the drying unit, a vector may be constructed based on the detection result of the sludge of the historical production data that is qualified in production quality or meets the requirement, such as (a, b, c, d) where a represents the water content before drying, b represents the water content after drying, c represents the gas overflow amount during drying, and d represents the drying time, and a, b, c, d respectively represent the values of the respective detection parameters.

In some embodiments, the clustering process may be performed by a clustering algorithm to obtain at least one cluster center. The type of clustering algorithm may include a variety, for example, the clustering algorithm may include K-Means clustering, density-based clustering method (DBSCAN), and the like. In some embodiments, each cluster center may correspond to a detection of sludge. In some embodiments, a vector may be constructed from the detection result of the currently dried sludge, a target clustering center may be determined based on the distance between the vector and each clustering center, and then the actual water content and the gas overflow amount of the drying unit of the cluster corresponding to the target clustering center may be averaged to serve as the value of the standard index.

In some embodiments, when determining a target cluster, a center vector of a plurality of clusters may be determined, and a corresponding target cluster may be determined based on a similarity of the center vector and a detection result of a currently dried sludge. Methods of calculating similarity may include, but are not limited to, cosine similarity, euclidean distance, pearson correlation coefficient, and the like.

For the carbonization unit, for example only, the value of the standard index is determined in a manner similar to the drying unit described above. In some embodiments, the value of the standard index of the drying unit may be determined first, then a vector is constructed, elements in the vector including the value of the standard index of the drying unit in addition to the detection result of the sludge, and then clustering and subsequent steps are performed to determine the value of the standard index of the carbonization unit.

In some embodiments, the time for the next batch of sludge to enter may be predicted based on data detected by the current batch of sludge through the first water content detection device of the sludge input unit, the second water content detection device and the first gas overflow amount detection device of the drying unit, and the second gas overflow amount detection device of the carbonization unit.

In some embodiments, each unit corresponds to a corresponding sludge treatment stage, first a sludge input system, the sludge input unit corresponding to an input stage; then drying the sludge, wherein the drying unit corresponds to a drying stage; carbonizing the dried sludge, wherein the carbonizing units correspond to carbonizing stages, and a plurality of carbonizing subunits respectively correspond to a first carbonizing stage, a second carbonizing stage and a third carbonizing stage … … (N can be a natural number which is not zero); and finally, outputting the carbonized sludge (carbide) to a system, wherein a carbide output unit corresponds to an output stage. In some embodiments, the completion time of each stage may be estimated by a predetermined time after the stage begins, and when the estimated time is less than a threshold, subsequent stages are not estimated. The threshold value may be preset. The estimation mode may be manually based on experience, or may be system automatic estimation, for example, the system may estimate through networking search or model prediction. Each stage corresponds to a production stage of each cell. In some embodiments, when the estimated time for a stage is less than the threshold, indicating that the next batch of sludge is needed soon, the subsequent stages of the batch need not be estimated.

In some embodiments, the time at which each stage is completed may be predicted based on the first model, and based on the predicted time at which each stage is completed, the time at which the next batch of sludge enters may be determined to achieve continuous production. It should be noted that continuous production means that the last batch of sludge and the next batch of sludge can be continuous, that is, the interval time between the entering of adjacent batches is extremely short or zero, so that uninterrupted continuous production of continuous feeding is realized.

In some embodiments, continuous production can be achieved so that each batch of sludge does not come too early, for example, after a batch is input by the sludge input unit, the next batch is input immediately, but the previous batch of sludge is not completed at a certain stage (for example, the first carbonization stage), and the next batch needs to wait for the previous unit (for example, the drying unit) all the time, which is not beneficial to production management. In addition, it may result in different production parameters between the two batches, which is not conducive to the standardized process of production control and sludge treatment. By the determination of the continuous time, the waiting time can be reduced.

In some embodiments, the first model may be a machine learning model, which may include a Recurrent Neural Network (RNN) model, or the like.

FIG. 4 is a schematic diagram of a first model shown in accordance with some embodiments of the present description. As shown in FIG. 4, in some embodiments, the inputs to the first model 430 may include the detection results 410 for a plurality of time points of the current stage and the standard values 420 for the subsequent stages, and the outputs of the first model 430 may be the time 440 for completion of the current stage and each subsequent stage. In some embodiments, the standard value for each stage may be the value of the standard index determined by clustering based on the historical production data construction vector described above.

For example only, after the sludge starts to be dried, the sludge detection result data corresponding to the drying time points 1, 2, and 3 (for example, corresponding to 10min, 20min, and 30min after the sludge starts to be dried) and the standard value of each carbonization subunit are input to the RNN model, and if the drying stage required time a1, the first carbonization stage required time B1, the second carbonization stage required time C1, and the third carbonization stage required time D1 of the RNN output are input, the time for the next batch of sludge to enter is predicted to be H1 — a1+ B1+ C1+ D1. If H1 is greater than the threshold value, after the sludge enters the first carbonization stage, the time B2 is determined by the first model, the time C2 is determined by the second carbonization stage, and the time D2 is determined by the third carbonization stage, so that the time for entering the next batch of sludge is predicted to be H2-B2 + C2+ D2. If H2 is less than the threshold, then no prediction is made, and the next batch is entered directly after H2.

The first model is trained in advance. The first model may be derived based on a plurality of training samples and label training. The training sample comprises detection results of a plurality of time points of a sample stage and standard values of a subsequent stage of the sample. The label is the time at which the sample phase and each subsequent phase are completed. The training data may be obtained based on historical data, and the labels of the training data may be determined by way of manual labeling.

In some embodiments, the input to the first model may also include temperature profile. In some embodiments, the temperature profile may include an infrared profile of the current and previous stages at a plurality of time points, and the temperature profile may be acquired by an infrared camera provided in the drying unit and the carbonizing unit. The plurality of time points for acquiring the infrared distribution map may be the same time point as the plurality of time points for acquiring the detection results, or may be different time points from the plurality of time points for acquiring the detection results.

In some embodiments, the temperature profile reflects to some extent the dehydration status of the sludge (e.g., higher temperature corresponds to faster dehydration rate), and inputting the temperature profile parameters to the first model can increase the accuracy of the first model prediction.

In some embodiments, the drying unit and the carbonization unit may be provided with infrared cameras for acquiring the temperature distribution of the sludge to determine the transport speed. In some embodiments, the higher the temperature of the drying unit and the carbonization unit is, the faster the drying and carbonization speed of the sludge is, and the drying and carbonization effect of the sludge is relatively better; the conveying speed is slow, the residence time in the drying unit and the carbonization unit is long, the longer the drying and carbonization action time on the sludge is, and the drying and carbonization effects of the sludge are relatively good. Therefore, the desired drying and carbonization effects can be obtained at an appropriate temperature and conveying speed.

In some embodiments, the delivery speed may be determined based on a second model, which may be a machine learning model, which may include a Recurrent Neural Network (RNN) model, or the like.

FIG. 5 is a schematic diagram of a second model shown in accordance with some embodiments of the present description. As shown in fig. 5, in some embodiments, the inputs to the second model 530 may include the infrared profile 510 for each of the preceding stages over a plurality of time periods and the standard gas spill amount 520 for the subsequent stage, and the output of the second model 530 may be whether the current preset delivery speed is feasible 540. If the production is feasible, the production is continued according to the current conveying speed, and if the production is not feasible, the conveying speed is adjusted. In some embodiments, the standard gas overrun 520 may be the value of a standard indicator determined by clustering based on historical production data construction vectors as described above.

In some embodiments, the inputs to the second model 530 may also include the completion time 550 for each subsequent stage. In some embodiments, the completion time for each subsequent stage may be the time at which each subsequent stage of the first model output is completed.

In some embodiments, by inputting the completion time of the subsequent stage predicted by the first model into the second model determining the conveying speed, it is possible to ensure that production is completed within the predicted time as much as possible.

The second model is trained in advance. The second model may be derived based on a plurality of training samples and label training. The training sample includes the infrared profile of each cell of the sample over a plurality of time periods, the standard gas emission of subsequent cells of the sample, and the completion time of each subsequent stage of the sample. The label may or may not be feasible at a preset feed speed. The training data may be obtained based on historical data, and the labels of the training data may be determined by way of manual labeling.
