Description

Technical Field

[0001] This invention relates to the field of funeral cremation technology, and in particular to a staged cremation method, system, electronic equipment and medium based on cremation smoke. Background Technology

[0002] The cremation fumes produced during the cremation of remains contain pollutants such as nitrogen oxides. If these fumes are released directly into the atmosphere without treatment, they will pollute the environment.

[0003] Currently, cremation of remains involves prolonged high-temperature (e.g., above 800°C) cremation in a crematorium, and the cremation fumes generated throughout the process are treated by a series of fume post-treatment devices.

[0004] However, different flue gas aftertreatment devices operate under different optimal conditions for treating pollutants with different characteristics. Using all flue gas aftertreatment devices in series results in low treatment efficiency and a tendency for ineffective flue gas treatment. Summary of the Invention

The different cremation stages specifically include a first cremation stage, a second cremation stage, and a third cremation stage. The first cremation stage is the time period from when the target remains enter the cremator furnace until the burning of the coffin, clothing, and hair associated with the target remains ends, and the organic matter of the target remains begins to burn. The second cremation stage is the time period from when the first cremation stage ends until the organic matter of the target remains is completely burned.

[0012] According to the present invention, a staged cremation method based on cremation flue gas includes, before applying different treatment processes to the cremation flue gas generated in different cremation stages based on the differences in the cremation flue gas generated in different cremation stages, the method further includes: reheating the cremation flue gas generated in each cremation stage in a re-combustion chamber; the re-combustion chamber is located at the front end of the exhaust flue of the cremator furnace; and the reheating time of the cremation flue gas in the re-combustion chamber is longer than the rated time.

[0013] According to the present invention, a staged cremation method based on cremation smoke is provided, which further includes, after controlling any target remains to enter the second cremation stage or the third cremation stage: controlling another remains to enter the first cremation stage; sequentially controlling the other remains to pass through the first cremation stage, the second cremation stage and the third cremation stage to complete the cremation of the other remains; the target remains and the other remains will not be in the same cremation stage at the same time.

[0014] According to the present invention, a staged cremation method based on cremation smoke includes, after acquiring cremation images of the target remains, the method further includes: inputting the cremation images into a state recognition model to obtain combustion adjustment parameters output by the state recognition model; the state recognition model is obtained by training using historical cremation image samples and parameter labels corresponding to the historical cremation image samples; adjusting the parameters of the heater and / or combustion air in any cremation stage based on the combustion adjustment parameters; and each cremation image carries information on the total cremation time.

[0015] Secondly, the present invention also provides a staged cremation system based on cremation smoke, comprising: a cremation control unit for controlling any target remains to sequentially pass through at least two cremation stages to complete the cremation of the target remains; and a smoke treatment unit for employing different treatment processes for the cremation smoke generated in different cremation stages based on the differences in the cremation smoke generated in different cremation stages; the treatment of the cremation smoke in each cremation stage is independent of each other.

[0016] Thirdly, the present invention provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of any of the above-described staged cremation methods based on cremation smoke.

[0017] Fourthly, the present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the staged cremation method based on cremation flue gas as described above.

[0030] The following is combined with Figures 1 to 5 This invention describes the staged cremation method, system, electronic equipment, and medium based on cremation flue gas provided by the present invention.

[0031] Figure 1 This is a schematic flowchart of the staged cremation method based on cremation flue gas provided by the present invention, as shown below. Figure 1 As shown, including but not limited to the following steps:

[0032] Step 101: Control any target remains to pass through at least two cremation stages in sequence to complete the cremation of the target remains.

[0033] Specifically, when cremating any target remains, the target remains are controlled to pass through at least two cremation stages in sequence to complete the cremation of the target remains.

[0034] As an optional embodiment, the target remains can sequentially pass through at least two cremation stages in the main furnace of the same furnace unit of the cremator. The operating environment parameters of the main furnace are adjusted to match the operating parameters corresponding to different cremation stages in order to complete the cremation of the target remains.

[0035] As another optional embodiment, the target remains can sequentially pass through at least two cremation stages in the main furnace of multiple furnace units of the cremator. By moving the target remains sequentially into different furnace units, and the operating environment parameters of the main furnace of at least two different furnace units are different, the target remains can sequentially pass through at least two cremation stages to complete the cremation of the target remains.

[0036] Step 102: Based on the differences in cremation fumes produced at different cremation stages, different treatment processes are adopted for the cremation fumes at different cremation stages.

[0037] The treatment of cremation fumes at each stage of cremation is independent of each other.

[0038] Specifically, since the cremation of the remains and burial goods is carried out in stages throughout the cremation process, the cremation smoke produced at different stages will be different. Therefore, different smoke treatment processes can be used to deal with the differences in cremation smoke at different stages.

[0039] Optionally, the treatment of cremation flue gas at different cremation stages is independent and does not affect each other, so that corresponding flue gas after-treatment equipment can be set up for the different cremation flue gas generated at different cremation stages.

[0040] As an optional embodiment, when the target remains are cremated in the main furnace of the same furnace unit of the cremator through at least two cremation stages, multiple independent flue gas treatment systems can be pre-configured in the main furnace, and a valve can be installed in each flue gas treatment system to control the connection and closure between the flue gas treatment system and the main furnace.

[0041] The number of flue gas treatment systems installed can correspond to the number of different cremation stages divided into the entire cremation process.

[0042] For example, if the entire cremation process is determined to include two different cremation stages, two independent flue gas treatment systems can be configured in the main furnace, called the first flue gas treatment system and the second flue gas treatment system. The valves installed in the first flue gas treatment system are called the first valves, and the valves installed in the second flue gas treatment system are called the second valves.

[0043] Correspondingly, the flue gas post-treatment equipment configured in the first flue gas treatment system is used to treat the cremation flue gas generated in one of the cremation stages, while the flue gas post-treatment equipment configured in the second flue gas treatment system is used to treat the cremation flue gas generated in another cremation stage.

[0044] Since the cremation fumes produced in the two cremation stages are different, the flue gas post-treatment equipment configured in the two flue gas treatment systems mentioned above will be selected according to the different characteristics of the cremation fumes.

[0045] For example, during the first cremation stage of the target remains, the first valve is opened and the other valves are closed. The cremation smoke generated during the first cremation stage will enter the first smoke treatment system through the first valve and be treated by the corresponding smoke post-treatment equipment within the first smoke treatment system. During the second cremation stage of the target remains, the second valve is opened and the other valves are closed. The cremation smoke generated during the second cremation stage will enter the second smoke treatment system through the second valve and be treated by the corresponding smoke post-treatment equipment within the second smoke treatment system.

[0046] As an alternative embodiment, when the target remains sequentially pass through at least two cremation stages in the main furnace of multiple furnace units of the cremator, each main furnace unit can be equipped with an independent flue gas treatment system in advance. For example, when the first cremation stage is carried out in the main furnace of the first furnace unit, the cremation flue gas generated in the first cremation stage will be treated by the corresponding flue gas post-treatment equipment in the flue gas treatment system of the first furnace unit; when the second cremation stage is carried out in the main furnace of the second furnace unit, the cremation flue gas generated in the second cremation stage will be treated by the corresponding flue gas post-treatment equipment in the flue gas treatment system of the second furnace unit.

[0047] Therefore, since the treatment of cremation flue gas at different stages is independent, corresponding flue gas after-treatment equipment can be selected based on the characteristics of the flue gas at each stage, eliminating the need for other unnecessary after-treatment equipment. For example, if the cremation flue gas generated at a certain cremation stage contains acidic gases and water vapor, then the corresponding flue gas treatment system can be equipped with a corresponding acid remover and dehumidifier, eliminating the need for other flue gas after-treatment equipment and improving flue gas treatment efficiency.

[0048] In existing technologies, when all flue gas aftertreatment equipment is connected in series for unified flue gas aftertreatment, the fly ash generated during the cremation stage becomes the main reaction surface for dioxin formation. It not only easily acts as a carrier, promoting the formation of dioxins and other pollutants from fatty organic matter in subsequent stages, but also tends to deposit on the flue and aftertreatment equipment pipes. This affects the flow of the flue, and the residual carbon, metals, metal oxides, or metal chlorides in the deposited fly ash can come into contact with subsequent flue gas, promoting the formation of dioxin-like pollutants. This application addresses this by pre-treating the fly ash generated during the cremation stage, effectively avoiding or mitigating these problems. Furthermore, by specifically treating the oily and acidic substances generated during the cremation stage, the difficulty of treating subsequent cremation flue gas can be effectively reduced, thereby significantly improving the efficiency of flue gas aftertreatment.

[0049] The present invention provides a staged cremation method based on cremation smoke. According to the staged characteristics of cremation smoke generated at different stages of cremation, the method adopts a refined staged processing process to fully utilize the working characteristics of different smoke post-processing equipment. This method can ideally ensure the processing quality of cremation smoke throughout the entire cremation process, improve the efficiency of each smoke post-processing device, and avoid the occurrence of ineffective smoke processing by some smoke post-processing devices.

[0050] Based on the above embodiments, as an optional embodiment, the cremation of the target remains may further include:

[0051] Images of the cremated remains of the target body were collected.

[0052] The cremation status of the target remains is determined based on cremation images.

[0053] Different cremation stages are defined based on the state of cremation.

[0054] The different cremation stages specifically include the first cremation stage, the second cremation stage, and the third cremation stage.

[0055] The first cremation stage is the period from when the target remains enter the crematorium furnace until the burning of the coffin, clothing, and hair associated with the target remains ends, and the organic matter of the target remains begins to burn.

[0056] The second cremation stage begins at the end of the first cremation stage and continues until the organic matter of the target remains is completely burned off.

[0057] The third cremation stage begins at the end of the second cremation stage and continues until the bones of the target remains are burned to ashes.

[0058] Specifically, windows can be opened on the side walls of each furnace unit, and high-temperature resistant cameras can be installed through the windows to capture cremation images of the target remains during cremation.

[0059] Furthermore, the cremation status of the target remains can be determined through the cremation image. For example, the cremation status of the target remains can be determined by the degree of cremation of different parts of the target remains.

[0060] The cremation process is further divided into different stages based on the cremation status of the target remains. These stages include the first cremation stage, the second cremation stage, and the third cremation stage.

[0061] The first cremation stage begins when the target remains enter the cremator's furnace and continues until the coffin, clothing, hair, and some combustible burial items (such as paper and cardboard) associated with the target remains have burned out, and the organic matter of the target remains (such as sugars, fats, and other flammable organic matter) begins to burn.

[0062] The second cremation stage begins at the end of the first cremation stage and continues until the organic matter (such as sugars, fats, and other flammable organic matter) of the target remains is completely burned.

[0063] The third cremation stage begins at the end of the second cremation stage and continues until the bones of the target remains are burned to ashes.

[0064] As an optional embodiment, when the target remains are cremated sequentially through the first, second, and third cremation stages within the main furnace of the same furnace unit of the cremator, the cremation status of the target remains is determined by acquiring cremation images. Based on this status, different cremation stages are then determined. For example, if the cremation images indicate that the organic matter of the target remains has begun to burn, and the burning of the coffin, clothing, and hair associated with the target remains has ended, then the target remains are determined to have completed the first cremation stage and entered the second cremation stage. The operating environment parameters of the main furnace are then adjusted accordingly.

[0065] As an alternative embodiment, when the target remains sequentially pass through the first cremation stage, the second cremation stage, and the third cremation stage within the main furnace of the multiple furnace units of the cremator, Figure 2 This is a schematic diagram of the cremator provided by the present invention, as shown below. Figure 2As shown, the cremator includes a first furnace unit 4, a second furnace unit 5, and a third furnace unit 6. Adjacent furnace units are connected by an openable furnace door 1. The target remains can first be placed on a trolley 3 and enter the main furnace 2 of the first furnace unit 4. The first cremation stage is completed by starting the first electric heater 7. The cremation images collected by the high-temperature resistant camera devices installed in the windows 28 on the side walls of each furnace unit can also be used to determine whether the target remains have completed the first cremation stage. After the first cremation stage is completed, the trolley 3 containing the remains is moved through the furnace door 1 and enters the second furnace unit 5. The second cremation stage is completed by starting the second burner 8. Then, the remains enter the third furnace unit 6 and the third cremation stage is completed by starting the third burner 9.

[0066] Optionally, multiple cremation images are used as sample data, and the corresponding cremation stage results are manually labeled as sample data labels. The sample data and sample data labels are used as training samples to pre-train the cremation stage recognition model (e.g., a convolutional neural network model can be used). Thus, the cremation stage corresponding to the cremation image of the target remains can be intelligently identified through the trained cremation stage recognition model.

[0067] The differences between remains of different ages and genders, as well as the different types of burial goods, will lead to significant variations in cremation images. Therefore, a diverse range of cremation images can be obtained as sample data. This involves acquiring multiple cremation images of different ages, genders, and types of burial goods at different cremation stages as sample data. These images are then manually labeled with the corresponding cremation stage results to form training samples. This pre-training process can effectively improve the cremation stage recognition model's ability to accurately identify the cremation stage corresponding to remains of different ages and genders, as well as different types of burial goods.

[0068] The present invention provides a staged cremation method based on cremation smoke, which acquires cremation images of the target remains, determines the cremation status of the target remains based on the cremation images, and divides the cremation status into a first cremation stage, a second cremation stage, and a third cremation stage, which helps to treat the cremation smoke generated at different cremation stages in a targeted manner.

[0069] Based on the above embodiments, as an optional embodiment, during the first cremation stage, the cremation flue gas includes fly ash, acidic gases, and water vapor.

[0070] Based on the differences in cremation fumes produced at different cremation stages, different treatment processes are adopted for the fumes at different cremation stages, specifically including:

[0071] A combination of filtration processes for removing acidic gases, fly ash, and moisture is used to filter the cremation flue gas generated during the first cremation stage.

[0072] Specifically, during the first cremation stage, the main components of the target remains are the coffin, clothing, hair, and combustible burial goods (such as paper and cardboard), which are burning. Therefore, the cremation smoke generated during the first cremation stage mainly includes a large amount of fly ash and acidic gases. In addition, the moisture in the remains will also evaporate at high temperatures, so the cremation smoke generated during the first cremation stage also includes water vapor.

[0073] Therefore, the treatment processes for the cremation flue gas generated in the first cremation stage mainly include a combination of filtration processes for removing acidic gases, removing fly ash, and removing moisture. Specifically, the acidic gas removal process can be achieved by using an acid remover, the fly ash removal process can be achieved by using an alkaline spray fly ash remover, and the moisture removal process can be achieved by using a dehumidifier.

[0074] Optionally, such as Figure 2 As shown, the first exhaust pipe 10 connected to the first furnace unit 4 is sequentially equipped with an alkaline spray fly ash remover 13 and a first dehumidifier 14, so that when the combustion flue gas generated in the first furnace unit 4 enters the main exhaust pipe 11 through the first exhaust pipe 10, it can pass through the alkaline spray fly ash remover 13 and the first dehumidifier 14 to effectively remove fly ash from the combustion flue gas and reduce its moisture content.

[0075] In addition, when the cremation flue gas passes through the alkaline spray fly ash remover, the alkaline solution can neutralize the acidic gas, thereby removing the acidic gas.

[0076] Optionally, such as Figure 2 As shown, each furnace unit can be equipped with a combustion air duct 15. One end of each combustion air duct 15 is connected to the main furnace 2 of the corresponding furnace unit, and the other end can be connected to a blower 16 for injecting air into the furnace unit. This can effectively improve the combustion efficiency in the main furnace 2 of each furnace unit by supplementing oxygen.

[0077] Optionally, such as Figure 2As shown, a heat exchanger 17 is also installed between the outer walls of the combustion air duct 15 and the flue gas sub-duct of each furnace unit. After the flue gas generated by combustion enters the heat exchanger 17, it will undergo a heat exchange process with the air in the combustion air duct 15, thereby transferring the heat carried by the flue gas to the air in the combustion air duct 15, thereby increasing the heat of the air in the combustion air duct 15. The air in the combustion air duct 15 is then injected into the main furnace 2 of the furnace unit, which is conducive to ensuring the combustion temperature in the main furnace 2, and can also further effectively reduce the heat carried away by the high-temperature flue gas, saving fuel energy.

[0078] The present invention provides a staged cremation method based on cremation flue gas, which performs targeted treatment according to the characteristics of the cremation flue gas generated in the first cremation stage, effectively improving the efficiency of flue gas post-treatment and the utilization efficiency of flue gas post-treatment equipment.

[0079] Based on the above embodiments, as an optional embodiment, during the second cremation stage, the cremation flue gas includes oily gases and acidic gases.

[0080] Based on the differences in cremation fumes produced at different cremation stages, different treatment processes are adopted for the fumes at different cremation stages, specifically including:

[0081] A combination of filtration processes for removing oily gases and filtration processes for removing acidic gases is used to filter the cremation fumes generated during the second cremation stage.

[0082] Specifically, during the second cremation stage, the main components of the target remains, as well as the flammable organic matter of the body, such as sugars and fats, are burning. Therefore, the cremation fumes generated during the second cremation stage mainly consist of oily gases and acidic gases.

[0083] Therefore, the treatment process for the cremation flue gas generated in the second cremation stage mainly includes a combination of filtration processes for removing oily gases and filtration processes for removing acidic gases. Specifically, the acidic gas removal process can be achieved by treating the flue gas through an acid remover, while the oily gas removal process can be achieved by treating the flue gas through an oil remover.

[0084] Optionally, such as Figure 2 As shown, the second exhaust pipe 18 connected to the second furnace unit 5 is equipped with an oil remover 19 and an acid remover 20 in sequence, so that when the combustion flue gas generated in the second furnace unit 5 enters the main exhaust pipe 11 through the second exhaust pipe 18, the oily gas and acidic gas in the combustion flue gas can be effectively removed.

[0085] Optionally, such as Figure 2As shown, if the acid remover 20 is a wet acid remover (e.g., acid removal by calcium hydroxide), a large amount of water vapor will be generated during the acid removal process. Therefore, a second dehumidifier 21 needs to be installed between the acid remover 20 and the main exhaust pipe 11. This will effectively reduce the moisture content of the combustion flue gas before it enters the main exhaust pipe 11.

[0086] If the acid remover 20 is not a wet acid remover, then there is no need to install a second dehumidifier 21. The combustion flue gas can enter the main exhaust pipe 11 after passing through the acid remover 20.

[0087] The present invention provides a staged cremation method based on cremation flue gas, which performs targeted treatment according to the characteristics of the cremation flue gas generated in the second cremation stage, effectively improving the efficiency of flue gas post-treatment and the utilization efficiency of flue gas post-treatment equipment.

[0088] Based on the above embodiments, as an optional embodiment, the cremation flue gas includes high-temperature smoke dust during the third cremation stage.

[0089] Based on the differences in cremation fumes produced at different cremation stages, different treatment processes are adopted for the fumes at different cremation stages, specifically including:

[0090] A filtration process for removing high-temperature smoke and dust is used to filter the cremation fumes generated during the third cremation stage.

[0091] Specifically, during the third cremation stage, the body is mainly cremated in the non-flammable parts and bones. The body will be completely cremated during this stage, and the ashes from the bones are easily blown away to form high-temperature smoke. Therefore, the cremation smoke generated during the third cremation stage mainly consists of high-temperature smoke.

[0092] Therefore, the main treatment processes for the cremation flue gas generated in the third cremation stage include filtration processes to remove high-temperature dust. These high-temperature dust removal processes can be performed using high-temperature dust collectors.

[0093] Optionally, such as Figure 2 As shown, the third exhaust pipe 22 connected to the third furnace unit 6 is equipped with a high-temperature dust collector 23, so that when the combustion flue gas generated in the third furnace unit 6 enters the main exhaust pipe 11 through the third exhaust pipe 22, a large amount of high-temperature dust in the combustion flue gas can be effectively removed.

[0094] The present invention provides a staged cremation method based on cremation flue gas, which performs targeted treatment according to the characteristics of the cremation flue gas generated in the third cremation stage, effectively improving the efficiency of flue gas post-treatment and the utilization efficiency of flue gas post-treatment equipment.

[0095] Based on the above embodiments, as an optional embodiment, after applying different treatment processes to the cremation flue gas at different cremation stages, the method further includes:

[0096] The flue gas from the initial filtration process is treated with processes for removing common pollutants and dust removal, and then discharged through a chimney.

[0097] Among them, common pollutants include at least dioxins and nitrogen oxides; primary filtration of cremation flue gas refers to cremation flue gas after being filtered using different treatment processes for the first, second, and third cremation stages.

[0098] Specifically, after preliminary filtration of the cremation flue gas generated in the three different cremation stages, all the cremation flue gas can be collected and further filtered using processes for removing common pollutants and dust removal, before being discharged through a chimney.

[0099] Among them, common pollutants include at least dioxins and nitrogen oxides. Processes for removing common pollutants can include flue gas treatment using activated carbon adsorption filtration devices, and dust removal processes can include flue gas treatment using bag filters.

[0100] Optionally, such as Figure 2 As shown, the cremation fumes with different characteristics generated in the three different cremation stages undergo targeted preliminary filtration treatment and are then drawn into the main exhaust duct 11. At the end of the main exhaust duct 11, an activated carbon adsorption filter 24, a bag filter 25, and a chimney 26 are sequentially installed. Therefore, the pre-filtered cremation fumes in the main exhaust duct 11 undergo common fumes treatment after passing through the activated carbon adsorption filter 24 and the bag filter 25 to ensure that the overall quality of the generated cremation fumes meets the standards, before being discharged through the chimney 26.

[0101] Optionally, such as Figure 2 As shown, an ejector fan 12 is also installed in the bag filter 25 and the chimney 26 of the main exhaust duct 11. When the ejector fan 12 is started, a negative pressure space will be formed in the main furnace 2 of each furnace unit, so that the combustion flue gas generated in each combustion stage can be continuously drawn into the corresponding exhaust sub-duct, and treated by the corresponding flue gas post-treatment equipment, before entering the main exhaust duct, and finally discharged in the chimney 26 after completing the common treatment.

[0102] Therefore, compared with the existing technology of treating cremation flue gas uniformly by connecting all flue gas after-treatment equipment in series, the present invention performs parallel targeted treatment of cremation flue gas with different characteristics generated at different cremation stages, and then performs a final series common treatment by summarizing all the targeted cremation flue gas. This can effectively improve the working efficiency of each flue gas after-treatment equipment and avoid the waste of the processing capacity of the flue gas after-treatment equipment (for example, the cremation flue gas generated in the third cremation stage already contains less gaseous pollutants. If it still passes through a flue gas after-treatment equipment for removing fly ash, oil and acid, it will cause a large waste of equipment processing capacity).

[0103] The present invention provides a staged cremation method based on cremation flue gas. After targeted treatment of the cremation flue gas generated at different cremation stages, it is aggregated for common treatment. This not only effectively overcomes the defects of using all flue gas post-treatment equipment in series in the prior art, but also effectively reduces the difficulty of cremation flue gas treatment, thereby greatly improving flue gas treatment efficiency and avoiding the waste of the treatment capacity of flue gas post-treatment equipment.

[0104] Based on the above embodiments, as an optional embodiment, before applying different treatment processes to the cremation fumes generated at different cremation stages based on the differences in the fumes produced at different cremation stages, the method further includes:

[0105] The cremation flue gas produced in each cremation stage is reheated in the recombustion chamber.

[0106] The re-combustion chamber is located at the front end of the exhaust flue of the furnace of the cremator.

[0107] The reheating time of the cremation flue gas in the recombustion chamber is longer than the rated time.

[0108] Specifically, the flue gas produced during cremation in the main furnace contains many harmful substances, which, when released into the atmosphere, can have a significant impact on the environment and human health, such as causing acid rain and ozone layer depletion. Therefore, reheating the cremation flue gas in the re-combustion chamber allows for the full oxidation and decomposition of these harmful substances, reducing their impact on the environment and human health.

[0109] Furthermore, to ensure complete combustion of the cremation flue gas in the recombustion chamber—that is, to ensure that the reheating time of the cremation flue gas in the recombustion chamber exceeds the rated time—the flue through which the flue gas flows from the recombustion chamber to the exhaust flue can be designed with a curved structure. The reheating time of the flue gas in the recombustion chamber can then be controlled by adjusting the complexity of the curvature. The rated time can be preset according to the specific usage requirements of the scenario, for example, it can be set to 2 seconds.

[0110] Optionally, Figure 3 yes Figure 2A cross-sectional view of the cremator at point AA, as shown below. Figure 3 As shown, a re-combustion chamber 27 is provided above the main furnace 2 of any furnace unit. The re-combustion chamber 27 is connected to the main furnace 2 so that the combustion flue gas in the main furnace 2 is reheated in the re-combustion chamber 27 and then discharged to the flue gas sub-pipe connected to the re-combustion chamber 27.

[0111] A heating device is installed in the re-combustion chamber 27. The heating device can be a third electric heater or a fourth burner. The combustion flue gas can be reheated by controlling the start of the heating device in the re-combustion chamber 27.

[0112] Optionally, the reheating time of the cremation flue gas in the recombustion chamber 27 can be controlled by adjusting the power of the ejector fan 12 to adjust the air velocity of the cremation flue gas.

[0113] The present invention provides a staged cremation method based on cremation flue gas, which reduces the impact of harmful substances in cremation flue gas on the environment and human health and improves the quality of flue gas post-treatment by setting up a re-combustion chamber to reheat the cremation flue gas generated during the cremation process.

[0114] Based on the above embodiments, as an optional embodiment, after controlling any target remains to enter the second or third cremation stage, the method further includes:

[0115] Control another body to enter the first cremation stage.

[0116] The cremation of another body is completed by sequentially controlling the first, second, and third cremation stages.

[0117] In this case, no target remains will be in the same cremation stage at the same time as another remains.

[0118] Specifically, after controlling any target remains to enter the second or third cremation stage, another remains can be controlled to enter the first cremation stage, and then the other remains can be controlled to pass through the first, second, and third cremation stages in sequence to complete the cremation of the other remains.

[0119] It should be noted that the cremation of any one target body and the other body will not be in the same cremation stage at the same time; that is, the cremation process of all bodies is independent and does not interfere with each other.

[0120] As an optional embodiment, such as Figure 2 As shown, after the control vehicle 3 enters the second furnace unit 5, that is, after controlling any target remains to enter the second cremation stage, the control vehicle 3 containing another remains enters the first furnace unit 4, that is, the control vehicle 3 to enter the first cremation stage.

[0121] Furthermore, after any target remains complete the second cremation stage and leave the second furnace unit 5, and the other remains complete the first cremation stage and enter the second furnace unit 5, that is, after entering the second cremation stage, another vehicle containing yet another remains can be controlled to enter the first furnace unit 4, that is, to control yet another remains to enter the first cremation stage.

[0122] In other words, up to three bodies can undergo different cremation stages in three different furnace units at the same time.

[0123] As another alternative embodiment, such as Figure 2 As shown, after the control vehicle 3 enters the third furnace unit 6, that is, after controlling any target remains to enter the third cremation stage, the control vehicle 3 containing another remains enters the first furnace unit 4, that is, the control vehicle 3 to enter the first cremation stage.

[0124] Furthermore, when the other body has completed the first and second cremation stages and entered the third cremation stage, another vehicle containing yet another body can be controlled to enter the first furnace unit 4, that is, to control yet another body to enter the first cremation stage.

[0125] In other words, a maximum of two bodies can undergo different cremation stages in three different furnace units at the same time.

[0126] Optionally, such as Figure 2 As shown, it also includes a closed trolley running track 29 for the trolley 3 to travel on, and at least one section of the trolley running track 29 runs through each furnace unit. That is to say, when the trolley 3 leaves the last furnace unit and the ashes on the trolley 3 have been collected and processed, the trolley 3 can return to the first furnace unit of the cremator along the closed track, so as to wait for the next cremation operation, and finally realize the continuous cycle of cremation process.

[0127] The staged cremation method based on cremation smoke provided by this invention can control another body to enter the first cremation stage after any target body has entered the second or third cremation stage, thereby realizing a continuous cycle of body cremation process and improving body cremation efficiency.

[0128] Based on the above embodiments, as an optional embodiment, after acquiring cremation images of the target remains, the method further includes:

[0129] The cremation image is input into the state recognition model to obtain the combustion adjustment parameters output by the state recognition model.

[0130] The state recognition model is obtained by training using historical cremation image samples and the parameter labels corresponding to the historical cremation image samples.

[0131] Based on the combustion adjustment parameters, adjust the parameters of the heater and / or combustion air during any cremation stage.

[0132] Each cremation image carries information about the total cremation time.

[0133] Specifically, the combustion adjustment parameters output by the state recognition model can be obtained by inputting the cremated images of the target remains into a pre-trained state recognition model.

[0134] The state recognition model is obtained by training historical cremation image samples and the parameter labels corresponding to the historical cremation image samples.

[0135] For example, a historical cremation image sample and the parameter label corresponding to the historical cremation image sample can be used as a training sample. Multiple training samples can be obtained as a training dataset, and then the training dataset can be input into the state recognition model. The model parameters in the state recognition model can be adjusted according to each output result of the state recognition model, and finally the pre-training process of the state recognition model is completed.

[0136] This can be interpreted as either completing the pre-training process of the state recognition model after reaching a predetermined number of pre-training iterations, or as completing the pre-training process of the state recognition model when the training output of the state recognition model converges.

[0137] Furthermore, by acquiring the combustion adjustment parameters output by the state recognition model, the parameters of the heater and / or combustion air during any cremation stage are adjusted. The heater can be an electric heater or a burner.

[0138] By adjusting the parameters of the heater, the cremation temperature and speed at any cremation stage can be adjusted; by adjusting the parameters of the combustion air (such as wind speed), the cremation temperature inside the furnace can be further effectively adjusted.

[0139] Therefore, by adjusting the parameters of the heater and / or combustion air, the cremation efficiency of each cremation stage of the target remains can be effectively adjusted. For example, when the current cremation stage is slow, the combustion adjustment parameters output by the state recognition model can be used to increase the operating temperature of the heater and increase the air intake speed of the combustion air to speed up the cremation.

[0140] Optionally, the total cremation time information carried by any cremation image can be used to confirm whether the cremation stage status corresponding to the current cremation image matches the total cremation time information, thereby determining whether the cremation stage status corresponding to the current cremation image is too fast or too slow.

[0141] The present invention provides a staged cremation method based on cremation flue gas, which obtains combustion adjustment parameters by inputting cremation images into a state recognition model, and then adjusts the parameters of the heater and / or combustion air based on the combustion adjustment parameters to achieve controllable cremation stages.

[0143] The cremation control unit 41 is used to control any target remains to pass through at least two cremation stages in sequence to complete the cremation of the target remains.

[0144] The flue gas treatment unit 42 is used to apply different treatment processes to the flue gas generated at different cremation stages based on the differences in the flue gas generated at different cremation stages.

[0145] The treatment of cremation fumes at each stage of cremation is independent of each other.
