Technical Field

[0001] The present disclosure relates to the technical field of garbage treatment, and particularly to a dynamic control method and system based on garbage incineration. Background Art

[0002] Currently, for domestic garbage or industrial garbage generated in society, in order to avoid adverse effects on the environment, most of the garbage is sent into a garbage incinerator for incineration to achieve harmless treatment of the garbage.

[0003] However, since the temperature inside the garbage incinerator is relatively high during operation and it is not suitable for placing electronic components, therefore, for the temperature control inside the garbage incinerator during operation, it is mostly manually completed by relevant personnel based on experience. This method is greatly affected by human factors and is prone to the situation where the temperature inside the furnace deviates from the expected temperature. Among them, too high a temperature inside the furnace will increase the risk of unexpected side reactions in the garbage incinerator, and too low a temperature inside the furnace may cause incomplete combustion of the garbage. That is to say, the garbage incineration effect of the existing garbage incinerator is poor. Summary of the Invention

[0020] Next, in combination with the accompanying drawings in the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0021] The embodiments of the present disclosure provide a dynamic control method based on waste incineration, as Figure 1 shown, the dynamic control method based on waste incineration includes:

[0022] Step 101: Collect the in-furnace image of the waste incinerator at the target moment.

[0023] Wherein, the target moment is a moment during the waste incineration stage of the waste incinerator.

[0024] It should be noted that at least one observation window is provided on the outer wall of the waste incinerator referred to in the present disclosure. The observation window is made of transparent high-temperature resistant glass (also called special glass). The observation window faces the waste incineration area of the waste incinerator, and the incineration situation of the waste stockpile in the waste incineration area can be observed through the observation window.

[0025] During the waste incineration stage of the waste incinerator, the aforementioned in-furnace image can be collected based on a pre-set image acquisition device. For example, the image acquisition device can be a camera, a webcam, etc. One observation window corresponds to one image acquisition device, and the image acquisition end of the image acquisition device faces the corresponding observation window.

[0026] In application, the waste stockpile can be understood as a mixture formed by stacking the waste to be incinerated in the stockpile yard, standing and fermenting for a set time and filtering the filtrate. The above waste stockpile is formed by stacking various types of waste, such as: paper, metal, ordinary glass, plastic, rubber, etc.

[0027] Step 102: Perform image analysis on the in-furnace image based on a pre-set mapping table to obtain target temperature information.

[0028] Wherein, the mapping table is used to represent the mapping relationship between the image pixel value and the temperature, and the target temperature information is used to represent: the maximum temperature and / or the average temperature in the furnace of the waste incinerator at the target moment.

[0029] Specifically, the mapping table can be understood as a data table that records the temperature values mapped by each image pixel value in the value range of the image pixel values. Based on the mapping table, the pixel values of each pixel point in the furnace image are mapped and converted, and the temperature value corresponding to each pixel point in the furnace image can be obtained. Among them, the maximum temperature in the furnace can be understood as the maximum temperature among the multiple temperature values corresponding to the multiple pixel points in the furnace image. Similarly, the average temperature in the furnace can be understood as the average temperature among the multiple temperature values corresponding to the multiple pixel points in the furnace image.

[0030] Exemplarily, the mapping table can be formed by measuring the pixel values of the images collected through the aforementioned high-temperature resistant glass at different temperatures.

[0031] Step 103: Adjust the furnace control index of the waste incinerator according to the difference between the target temperature information and the preset temperature information.

[0032] Among them, when the target temperature information includes the maximum temperature in the furnace, the preset temperature information includes the maximum set temperature. When the target temperature information includes the average temperature in the furnace, the preset temperature information includes the set average temperature.

[0033] The difference between the target temperature information and the preset temperature information can be understood as:

[0034] The temperature difference between the maximum temperature in the furnace and the maximum set temperature;

[0035] Or,

[0036] The temperature difference between the average temperature in the furnace and the set average temperature;

[0037] Or,

[0038] The weighted average value of the maximum temperature difference and the average temperature difference. The maximum temperature difference is the temperature difference between the maximum temperature in the furnace and the maximum set temperature, and the average temperature difference is the temperature difference between the average temperature in the furnace and the set average temperature.

[0039] Among them, the above temperature difference or weighted average value has positive and negative differences. When it is positive, it indicates that the actual temperature in the furnace reflected by the target temperature information is higher than the set temperature reflected by the preset temperature information. When it is negative, it indicates that the actual temperature in the furnace reflected by the target temperature information is lower than the set temperature reflected by the preset temperature information.

[0040] It should be understood that after adjusting the furnace control index of the waste incinerator according to the difference between the target temperature information and the preset temperature information, the actual temperature in the furnace of the waste incinerator will approach the set temperature reflected by the preset temperature information.

[0041] Specifically, the furnace control index includes at least one of the following:

[0042] The number of opened flame nozzles of the waste incinerator;

[0043] The flame temperature of the flame nozzles of the waste incinerator;

[0044] The input amount / input rate of the combustion-supporting material of the waste incinerator.

[0045] Wherein, when the actual temperature in the furnace reflected by the target temperature information is higher than the set temperature reflected by the preset temperature information, at least one of the following measures can be taken:

[0046] Reduce the number of opened flame nozzles;

[0047] Lower the flame temperature of the flame nozzles;

[0048] Reduce the input amount / input rate of the combustion-supporting material.

[0049] And when the actual temperature in the furnace reflected by the target temperature information is lower than the set temperature reflected by the preset temperature information, at least one of the following measures can be taken:

[0050] Increase the number of opened flame nozzles;

[0051] Raise the flame temperature of the flame nozzles;

[0052] Increase the input amount of the combustion-supporting material.

[0053] Exemplarily, the combustion-supporting material may include: combustion-supporting gases (such as: oxygen, chlorine, fluorine), combustion promoters, slurry dispersants, water separators, ash modifiers, emulsifiers, catalysts, etc.

[0054] In this application, by collecting the image inside the waste incinerator during the waste incineration stage and analyzing the image inside the furnace in combination with a preset mapping table, the pixel values of each pixel point in the image inside the furnace are converted into temperatures, and then the target temperature information representing the maximum temperature and / or the average temperature inside the furnace of the waste incinerator at the target moment is obtained. Then, the difference between the target temperature information and the preset temperature information is compared, and based on this, the automatic adjustment of the furnace control index of the waste incinerator is completed to replace the temperature control measures of manual operation, avoid the adverse effects brought by human factors, make the incineration temperature of the adjusted waste incinerator approach the temperature indicated by the preset temperature information, reduce the occurrence probability of side reactions and the risk of incomplete waste combustion, and enable the waste incinerator to obtain a better waste incineration effect.

[0055] It should be noted that in the application, the furnace images can be collected periodically, and the furnace control indicators of the waste incinerator are adjusted only when the difference between the target temperature information and the preset temperature information is greater than the set difference threshold; while when the difference between the target temperature information and the preset temperature information is less than or equal to the difference threshold, the furnace control indicators of the waste incinerator are not adjusted, so as to realize the dynamic temperature control of the waste incinerator, make the actual incineration effect of the waste incinerator as close as possible to the expected incineration effect, and after the actual incineration effect of the waste incinerator approaches the expected incineration effect, by means of non-regulation, to avoid over-regulation of the waste incinerator and reduce the energy consumption of the relevant equipment for regulation.

[0056] In some embodiments, a plurality of observation windows can be arranged in an array on the outer wall of the waste incinerator, so as to collect a plurality of furnace images based on a plurality of image acquisition devices respectively corresponding to the plurality of observation windows at the target moment, and obtain a plurality of temperature information respectively corresponding to the plurality of furnace images based on the mapping table, and then perform a mean calculation on the plurality of temperature information, so as to obtain the target temperature information.

[0057] Compared with the method of obtaining the target temperature information through a single image acquisition device, the above setting can reduce the adverse impact of external interference on the target temperature information and keep the obtained target temperature information highly accurate.

[0058] In one embodiment, the method further includes:

[0059] Collect the flue gas image of the waste incinerator at the target moment;

[0060] Among a plurality of reference images stored in the database, determine a target reference image, where one of the reference images corresponds to a temperature correction coefficient, and the temperature correction coefficients corresponding to different reference images are different. The temperature correction coefficient is used to represent the numerical interference of the flue gas condition reflected by the corresponding reference image on the pixel value of the image. The target reference image is the reference image with the largest similarity value between the plurality of reference images and the flue gas image, and the similarity value is the numerical representation of the similarity between the corresponding reference image and the flue gas image;

[0061] The image analysis of the furnace image based on the preset mapping table to obtain the target temperature information includes:

[0062] Correct the pixel value of each pixel point in the furnace image based on the temperature correction coefficient corresponding to the target reference image to obtain a corrected image;

[0063] Perform image analysis on the corrected image based on the mapping table to obtain the target temperature information.

[0064] In this embodiment, in the case where flue gas may be generated during the waste incineration process, by collecting flue gas images and combining the method of comparing image similarities, the corresponding temperature correction coefficient is determined, that is, the numerical interference of the flue gas in the furnace on the pixel values of each pixel point in the collected furnace image at the target moment is determined. Accordingly, the pixel values of each pixel point in the collected furnace image are corrected, and then image analysis is performed on the corrected furnace image (i.e., the corrected image) based on the mapping table, which can make the obtained target temperature information more accurate and reliable.

[0065] Among them, the flue gas image of the waste incinerator at the target moment and the furnace image of the waste incinerator at the target moment can be the same image.

[0066] Exemplarily, the process of correcting the pixel value of each pixel point in the furnace image based on the temperature correction coefficient corresponding to the target reference image can be:

[0067] Increase / decrease the pixel value of each pixel point in the furnace image by a set value. For example:

[0068] The pixel value of each pixel point in the furnace image can be processed as +2. Among them, if the value after adding 2 to the pixel value of a certain pixel point in the furnace image is greater than the set maximum pixel value (usually 255), then the pixel value of a certain pixel point after correction is the set maximum pixel value;

[0069] The pixel value of each pixel point in the furnace image can also be processed as -2. Among them, if the value after subtracting 2 from the pixel value of a certain pixel point in the furnace image is less than the set minimum pixel value (usually 0), then the pixel value of a certain pixel point after correction is the set minimum pixel value.

[0070] Exemplarily, the pixel values of the images collected through the aforementioned high-temperature resistant glass in the case of no smoke can be tested first, and then, under the condition that other conditions remain unchanged, the images collected through the aforementioned high-temperature resistant glass under different flue gases can be tested to obtain the multiple reference images. Then, by comparing the pixel values of each reference image with the pixel values of the no-smoke image, the temperature correction coefficient corresponding to each reference image can be obtained.

[0071] In one embodiment, two light-transmitting areas are provided on the outer wall of the exhaust part of the waste incinerator. The two light-transmitting areas are arranged oppositely. A light-emitting device and a light-sensitive device are respectively provided on both sides of the exhaust part of the waste incinerator. The light-emitting surface of the light-emitting device faces one of the light-transmitting areas, and the light-sensitive surface of the light-sensitive device faces the other light-transmitting area;

[0072] The method further includes:

[0073] Based on the light-sensitive device, the light emitted by the light-emitting device at the first moment is collected to obtain a detection optical signal, where the first moment is a moment during the stage when the waste incinerator is preparing to discharge tail gas;

[0074] According to the difference between the detection optical signal and the reference optical signal corresponding to the light-emitting device, a light attenuation value is determined, and the light attenuation value is used to represent the light energy attenuation amplitude of the light emitted by the light-emitting device;

[0075] When the preset exhaust conditions are met, the waste incinerator is controlled to discharge tail gas;

[0076] Among them, the exhaust conditions include: the light energy attenuation amplitude indicated by the light attenuation value is less than or equal to a preset amplitude threshold.

[0077] In application, the light-transmitting area can be a light-transmitting window made of transparent high-temperature resistant glass.

[0078] The detection optical signal at least includes the light energy when the reference optical signal is emitted. During the transmission of the reference optical signal, affected by the possible soot interference in the tail gas, the light energy of the reference optical signal will gradually attenuate, and as the soot concentration increases, the light energy attenuation amplitude of the reference optical signal will also increase. Therefore, by using the characteristic that the light energy attenuation amplitude of the reference optical signal is positively correlated with the soot concentration in the waste incinerator, the soot concentration in the tail gas of the waste incinerator can be indirectly determined by calculating the light attenuation parameter.

[0079] In this embodiment, based on the mutual cooperation of the light-sensitive device, the light-emitting device and the light-transmitting area, the detection of the soot concentration of the tail gas to be discharged in the waste incinerator can be conveniently realized, and it is set that when the soot concentration of the tail gas is low, that is, when the light energy attenuation amplitude indicated by the light attenuation value is less than or equal to the preset amplitude threshold, the waste incinerator is controlled to discharge tail gas, so as to meet the harmless requirement for tail gas discharge in actual application.

[0080] In application, after standing for a certain period of time (such as 1 hour) in the exhaust part of the waste incinerator, the above process can be executed based on the light-sensitive device and the light-emitting device to detect whether the soot concentration of the tail gas in the exhaust part reaches the exhaust conditions. If so, the tail gas is discharged. If not, after standing for the same period of time again, the above process is executed again based on the light-sensitive device and the light-emitting device, and it is detected again whether the soot concentration of the tail gas in the exhaust part reaches the exhaust conditions. The above process is repeated until the soot concentration of the tail gas in the exhaust part reaches the exhaust conditions.

[0081] Among them, relevant components for absorbing soot can be set in the exhaust part of the waste incinerator to accelerate the reduction rate of the soot concentration in the tail gas.

[0082] In one embodiment, after determining the optical attenuation value, the method further includes:

[0083] When the attenuation amplitude of the optical energy indicated by the optical attenuation value is less than or equal to the amplitude threshold, perform tail gas component detection based on the gas sensor provided in the exhaust part of the waste incinerator to obtain a tail gas detection result, and the tail gas detection result is used to indicate whether the tail gas to be discharged from the waste incinerator contains toxic substances;

[0084] The exhaust condition further includes: the tail gas to be discharged from the waste incinerator does not contain toxic substances.

[0085] In this embodiment, when it is detected that the soot concentration in the tail gas to be discharged meets the exhaust condition, it is further detected whether the tail gas to be discharged contains toxic substances, and tail gas discharge is only carried out when it is determined that the tail gas to be discharged does not contain toxic substances, otherwise tail gas discharge is not carried out, so as to meet the harmless requirement for tail gas discharge in actual applications.

[0086] Among them, it is set that when the attenuation amplitude of the optical energy indicated by the optical attenuation value is less than or equal to the amplitude threshold, that is, when the soot concentration in the tail gas to be discharged is relatively low, the relevant detection instrument is started to detect the toxic substances in the tail gas to be discharged. On the one hand, it is to avoid the interference of soot on the detection of toxic substances and ensure the accuracy of the toxic substance detection result. On the other hand, it is to reduce the probability of soot entering the relevant detection instrument and avoid excessive attenuation of the service life of the relevant detection instrument.

[0087] In application, a sealed housing can be set to enclose the relevant detection instrument provided in the exhaust part. When the attenuation amplitude of the optical energy indicated by the optical attenuation value is less than or equal to the amplitude threshold, the sealed housing is controlled to open to allow the relevant detection instrument to detect toxic substances, and after the detection is completed, the sealed housing is closed again.

[0088] Exemplarily, the tail gas to be discharged can be purified by a gas purification component preset in the exhaust part to filter out the toxic substances in the tail gas to be discharged.

[0089] For example, the toxic substances may include: ammonia, ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, hydrogen sulfide, etc.

[0090] In one embodiment, before collecting the light emitted by the light-emitting device at the first moment by the photosensitive device to obtain a detection optical signal, the method further includes:

[0091] Based on the light sensing device, the light emitted by the light emitting device at the second moment is collected to obtain a calibration optical signal, where the second moment is a moment during the waste incinerator's waste incineration preparation stage and the second moment is earlier than the first moment;

[0092] Update the reference optical signal of the light emitting device according to the calibration optical signal.

[0093] In this embodiment, for the case where the light transmittance of the light-transmitting area of the exhaust part is greatly affected by ambient light and dust adhered to the surface of the light-transmitting area, before detecting the aforementioned soot concentration, by collecting the calibration optical signal of the exhaust part in the absence of smoke and updating the reference optical signal accordingly, the influence of external interference on the reference optical signal can be reduced, making the subsequent calculated optical attenuation value more accurate.

[0094] Among them, updating the reference optical signal of the light emitting device according to the calibration optical signal can be:

[0095] Determine the calibration optical signal as the latest reference optical signal of the light emitting device.

[0096] It should be understood that the various stages of the operation process of the waste incinerator are in sequence: waste incineration preparation stage (feeding the waste pile into the waste incinerator), waste incineration stage (burning the waste pile), preparation for exhaust gas stage (the waste pile stops burning, and it is detected whether the exhaust gas to be discharged meets the exhaust conditions), exhaust and slag discharge and furnace shutdown stage (discharging the exhaust gas and slag, and preparing for the next waste incineration).
