DETAILED DESCRIPTION

[0064] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0065] In the description of the present invention, if there is a description of first, second, etc., it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0066] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0067] In the description of the present invention, it should be noted that, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0068] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0069] See also Figure 1 FIG. 1 is a flow chart of a method for controlling a drying and pyrolysis integrated furnace according to an embodiment of the present invention. The method is applied to a drying and pyrolysis integrated furnace device, and includes the following steps:

[0070] Obtain the stirring torque parameter, pyrolysis gas moisture content parameter, and kiln weight parameter. The stirring torque parameter indicates the torque value during the stirring rotation of the drying and pyrolysis integrated furnace. The pyrolysis gas moisture content parameter indicates the moisture content of the pyrolysis gas discharged from the drying and pyrolysis integrated furnace. The kiln weight parameter indicates the weight of the drying and pyrolysis integrated furnace at both ends.

[0071] Using the thermal database, the stirring torque parameters, pyrolysis gas moisture content parameters and kiln weight parameters are compared to adjust the feed rate, heat load and furnace speed of the drying and pyrolysis integrated furnace equipment. The thermal database includes at least a first relationship curve, a second relationship curve and a third relationship curve. The first relationship curve represents the corresponding relationship between the stirring torque parameter and the feed rate, the second relationship curve represents the corresponding relationship between the pyrolysis gas moisture content parameter and the heat load, and the third relationship curve represents the corresponding relationship between the kiln weight parameter and the furnace speed.

[0072] Specifically, if Figure 1 As shown, it can be understood that the stirring torque parameter can reflect the degree of drying and particle size of the sludge, the pyrolysis gas moisture content parameter can reflect the screening and particle size of the sludge through the drying zone, and the kiln weight parameter can reflect the sludge dehydration and the heat load matching of the rotary kiln. Therefore, by obtaining the above three types of parameters in real time, it is possible to monitor whether they are in a relatively stable and ideal parameter range. Once the parameter value exceeds or falls below the preset parameter range, that is, it cannot be matched on each relationship curve, the feed rate, heat load and furnace speed of the drying and pyrolysis integrated furnace equipment are adjusted, thereby changing the working state of the drying and pyrolysis integrated furnace equipment, so that the above parameters can fall back to a reasonable parameter range, thereby making the working state of the drying and pyrolysis integrated furnace equipment sustainable and stable.

[0073] Furthermore, adjusting the feed rate is to adjust the processing capacity of the rotary kiln; adjusting the heat load is to adjust the drying degree of the material and the moisture content of the sludge; adjusting the furnace speed is to adjust the particle uniformity, drying degree and discharge speed of the material.

[0074] It is understandable that during the operation of a drying and pyrolysis integrated furnace, changes in sludge quality (e.g., changes in moisture content) can lead to uneven sludge mixing and unstable dehydration rates during the drying phase. Therefore, the control method of the present invention uses a comprehensive assessment of the degree of drying and carbonization using multiple parameters—the mixing torque parameter, the pyrolysis gas moisture content parameter, and the kiln weight parameter—to control the equipment's operating parameters, such as heat load, rotational speed, and feed rate, to achieve stable control of the integrated furnace's operating conditions.

[0075] In this embodiment, by obtaining the stirring torque parameter, the pyrolysis gas moisture content parameter and the kiln weight parameter in real time, the various parameter indicators of the drying and pyrolysis integrated furnace equipment can be monitored; then the theoretical correspondence between the parameters in the thermal database is used, which is specifically expressed as a relationship curve, to compare and determine whether the stirring torque parameter, the pyrolysis gas moisture content parameter and the kiln weight parameter are in the corresponding theoretical optimal state, and the feed rate, heat load and furnace speed of the drying and pyrolysis integrated furnace equipment are continuously adjusted accordingly to ensure that the working state indicators of the drying and pyrolysis integrated furnace equipment are within the ideal preset range, that is, to ensure that the material stirring is uniform, the material processing speed is stable and the material pyrolysis degree is stable. Therefore, the drying and pyrolysis integrated furnace control method of the embodiment of the present invention can be well applied to the drying and pyrolysis integrated furnace equipment, and the sludge carbonization and pyrolysis trend can be predicted during the working process, and the relevant working parameters can be adjusted based on this judgment, which can well meet the comprehensive requirements of sludge dehydration rate, particle fineness and efficient carbonization.

[0076] In some embodiments, a thermal engineering database is used to compare stirring torque parameters, pyrolysis gas moisture content parameters, and kiln weight parameters to adjust the feed rate, heat load, and furnace speed of the drying and pyrolysis integrated furnace equipment, including the following steps:

[0077] If the stirring torque parameter does not match the first relationship curve, adjust the feed speed;

[0078] If the pyrolysis gas moisture content parameter does not match the second relationship curve, adjust the heat load;

[0079] If the kiln weight parameter does not match the third relationship curve, adjust the furnace speed.

[0080] Specifically, it can be understood that, according to the degree of correlation between the parameters, there is a high correlation between the stirring torque parameter and the feed rate, between the pyrolysis gas moisture content parameter and the heat load, and between the kiln weight parameter and the furnace body speed. When the stirring torque parameter is not within the preset reasonable parameter range, prioritizing the adjustment of the feed rate can better control the uniform stirring of the material; when the pyrolysis gas moisture content parameter is not within the preset reasonable parameter range, prioritizing the adjustment of the heat load can better control the stability of the material processing speed; when the kiln weight parameter is not within the preset reasonable parameter range, prioritizing the adjustment of the furnace body speed can better control the degree of pyrolysis of the material. Therefore, the first relationship curve, the second relationship curve, and the third relationship curve are the correspondences between the most important parameters used for matching and comparison in the control method of the embodiment of the present invention.

[0081] In some embodiments, the thermal database further includes a fourth relationship curve, a fifth relationship curve, and a sixth relationship curve. The fourth relationship curve represents the corresponding relationship between the stirring torque parameter and the heat load. The fifth relationship curve represents the corresponding relationship between the pyrolysis gas moisture content parameter and the feed rate. The sixth relationship curve represents the corresponding relationship between the kiln weight parameter and the feed rate.

[0082] Using the thermal engineering database, the stirring torque parameters, pyrolysis gas moisture content parameters and kiln weight parameters are compared to adjust the feed rate, heat load and furnace speed of the drying and pyrolysis integrated furnace equipment. The following steps are also included:

[0083] If the stirring torque parameter does not match the fourth relationship curve, adjust the heat load;

[0084] If the pyrolysis gas moisture content parameter does not match the fifth relationship curve, adjust the feed rate;

[0085] If the kiln weight parameter does not match the sixth relationship curve, adjust the feed rate.

[0086] Specifically, it can be understood that, based on the comparison and judgment using the first relationship curve, the second relationship curve and the third relationship curve and the control adjustment, if the working condition of the integrated pyrolysis furnace equipment has not been significantly improved or has not reached the ideal state, the fourth relationship curve, the fifth relationship curve and the sixth relationship curve can be further used to further adjust the heat load and the feed rate so that the stirring torque parameters, the pyrolysis gas moisture content parameters and the kiln weight parameters can be within the preset reasonable parameter range.

[0087] Furthermore, it can be understood that the correlation between parameters reflected by the fourth relationship curve, the fifth relationship curve and the sixth relationship curve is slightly weaker than the correlation between parameters reflected by the first relationship curve, the second relationship curve and the third relationship curve. Therefore, the method steps of this embodiment are equivalent to further correction and adjustment to improve the control method so that the working state of the equipment is as stable as possible.

[0088] In some embodiments, the thermal database further includes a seventh relationship curve, an eighth relationship curve, and a ninth relationship curve. The seventh relationship curve represents the corresponding relationship between the stirring torque parameter and the furnace body speed. The eighth relationship curve represents the corresponding relationship between the pyrolysis gas moisture content parameter and the furnace body speed. The ninth relationship curve represents the corresponding relationship between the kiln weight parameter and the heat load.

[0089] Using the thermal engineering database, the stirring torque parameters, pyrolysis gas moisture content parameters and kiln weight parameters are compared to adjust the feed rate, heat load and furnace speed of the drying and pyrolysis integrated furnace equipment. The following steps are also included:

[0090] If the stirring torque parameter does not match the seventh relationship curve, adjust the furnace speed;

[0091] If the pyrolysis gas moisture content parameter does not match the eighth relationship curve, adjust the furnace speed;

[0092] If the kiln weight parameter does not match the ninth relationship curve, adjust the heat load.

[0093] Specifically, it can be understood that, on the basis of comparing and judging and performing control adjustments using the first to sixth relationship curves, in order to enable the equipment to operate in the best stable state, the seventh, eighth and ninth relationship curves can be further used to further adjust the furnace speed and heat load, so that the stirring torque parameters, pyrolysis gas moisture content parameters and kiln weight parameters can be at the best parameter values.

[0094] Furthermore, it can be understood that the correlation between parameters reflected by the seventh relationship curve, the eighth relationship curve and the ninth relationship curve is slightly weaker than the correlation between parameters reflected by the first relationship curve, the second relationship curve and the third relationship curve. Therefore, the method steps of this embodiment are equivalent to further correction and adjustment. After multiple adjustments and corrections, the working state of the equipment can be in the best stable state.

[0095] In addition, if Figure 2As shown, an embodiment of the present invention further provides a drying and pyrolysis integrated furnace control system, including: a data acquisition module 110 and a data processing module 120. The data acquisition module 110 is used to obtain the stirring torque parameter, the pyrolysis gas moisture content parameter and the kiln weight parameter. The stirring torque parameter represents the torque value information of the drying and pyrolysis integrated furnace equipment during stirring and rotation. The pyrolysis gas moisture content parameter represents the moisture content information of the pyrolysis gas discharged from the drying and pyrolysis integrated furnace equipment. The kiln weight parameter represents the weight information at both ends of the furnace body of the drying and pyrolysis integrated furnace equipment. The data processing module 120 is used to use the thermal database to compare the stirring torque parameter, the pyrolysis gas moisture content parameter and the kiln weight parameter to adjust the feed rate, heat load and furnace body speed of the drying and pyrolysis integrated furnace equipment. The thermal database includes at least a first relationship curve, a second relationship curve and a third relationship curve. The first relationship curve represents the corresponding relationship between the stirring torque parameter and the feed rate, the second relationship curve represents the corresponding relationship between the pyrolysis gas moisture content parameter and the heat load, and the third relationship curve represents the corresponding relationship between the kiln weight parameter and the furnace body speed.

[0096] Specifically, refer to Figure 2 It can be understood that the drying and pyrolysis integrated furnace control system of the embodiment of the present application is used to implement the drying and pyrolysis integrated furnace control method. The drying and pyrolysis integrated furnace control system of the embodiment of the present application corresponds to the aforementioned drying and pyrolysis integrated furnace control method.

[0097] In this embodiment, by using the data acquisition module 110 to obtain the stirring torque parameter, the pyrolysis gas moisture content parameter, and the kiln weight parameter in real time, the various parameter indicators of the drying and pyrolysis integrated furnace equipment can be monitored; then, based on the data processing module 120, the theoretical correspondence between the various parameters in the thermal database is used, specifically expressed as a relationship curve, to compare and determine whether the stirring torque parameter, the pyrolysis gas moisture content parameter, and the kiln weight parameter are in the corresponding theoretical optimal state, and the feed rate, heat load, and furnace speed of the drying and pyrolysis integrated furnace equipment are continuously adjusted accordingly to ensure that the working state indicators of the drying and pyrolysis integrated furnace equipment are within the ideal preset range, that is, to ensure that the material stirring is uniform, the material processing speed is stable, and the material pyrolysis degree is stable. Therefore, the drying and pyrolysis integrated furnace control system of the embodiment of the present invention can be well applied to the drying and pyrolysis integrated furnace equipment, and the sludge carbonization and pyrolysis trends can be predicted during the working process, and the relevant working parameters can be adjusted based on this judgment, which can well meet the comprehensive requirements of sludge dehydration rate, particle fineness, and efficient carbonization.

[0099] In some embodiments, the thermal database further includes a fourth relationship curve, a fifth relationship curve, and a sixth relationship curve. The fourth relationship curve represents the correspondence between the stirring torque parameter and the heat load, the fifth relationship curve represents the correspondence between the pyrolysis gas moisture content parameter and the feed rate, and the sixth relationship curve represents the correspondence between the kiln weight parameter and the feed rate. The data processing module 120 further includes: a fourth processing unit, a fifth processing unit, and a sixth processing unit.

A plurality of repetition zones and a plurality of screening zones 223 are provided in the drying zone 221. In some embodiments, such as Figure 3 As shown, the drying zone 221 is configured as a two-stage stirring and screening zone. In some embodiments, the gas separation mechanism 230 utilizes a gas separation bag, with a pyrolysis gas outlet 231 provided on the upper side of the gas separation bag and a pyrolysis carbon outlet 232 provided on the lower side of the gas separation bag. The stirring mechanism 240 is used to rotate the furnace body 220 about the central axis. The torque collection device 250 is disposed near the stirring mechanism 240.

[0103] Furthermore, it can be understood that the process flow of the equipment of this embodiment is specifically as follows: organic solid waste materials such as sludge enter the equipment from the feed port 211, first enter the drying zone 221 for drying and dehydration, and undergo multiple stirring and screening during the drying and dehydration process. The stirring zone 222 is correspondingly provided with a stirring mechanism 240, so that the material is stirred during the rotation of the pyrolysis furnace to accelerate the drying of the material; a screening mesh structure is provided in the screening zone 223 to screen and crush the material to prevent agglomeration.

The material passing through the drying area 221 then enters the carbonization area 224. After carbonization in the carbonization area 224, the material is discharged from the outlet of the furnace body 220. The pyrolysis gas in the material product is discharged from the upper outlet of the gas separator, and the pyrolysis char in the material product is discharged from the lower outlet of the gas separator.
