Description

Technical Field

[0001] This invention relates to medical waste treatment technology, specifically to a method and system for adjusting the load of the high-temperature pyrolysis chamber in a thermomagnetic vaporization device. Background Technology

[0002] A thermomagnetic gasification device is a device that uses the introduction of an oxygen-containing magnetized gas (also known as a thermomagnetic field environment) to magnetize and pyrolyze organic or medical waste. The pyrolysis gas is then subjected to further high-temperature secondary pyrolysis and combustion (here, high temperature refers to heating the pyrolysis gas to above 600°C). Finally, the flue gas after combustion is treated to achieve compliant emissions. Devices using similar principles are also called magnetized pyrolysis devices, magnetized pyrolysis devices, or magnetized incineration devices. The thermomagnetic gasification device referred to in this invention also includes magnetized pyrolysis devices, magnetized pyrolysis devices, or magnetized incineration devices using similar principles.

[0003] Thermomagnetic vaporization devices are commonly used to treat medical waste and other organic solid waste. They typically include a magnetized pyrolysis vaporization chamber, a high-temperature pyrolysis chamber, and a tail gas treatment system. The magnetized pyrolysis vaporization chamber uses an oxygen-containing magnetized gas (usually air) to magnetize and vaporize organic or medical waste, generating pyrolysis gas. This pyrolysis gas then enters the high-temperature pyrolysis chamber for further high-temperature secondary pyrolysis and combustion. Finally, the combustion exhaust gas is discharged to the subsequent tail gas treatment system for treatment.

[0004] Because the pyrolysis gasification process requires the participation of magnetized gas containing oxygen (usually air), the amount of magnetized gas entering the magnetized pyrolysis gasification chamber, as well as the subsequent high-temperature secondary pyrolysis and pyrolysis gas combustion processes, all require strict control of process parameters; otherwise, continuous operation of the aforementioned processes is difficult. Furthermore, since the entire process, from pyrolysis gasification and high-temperature secondary pyrolysis to the final combustion of the pyrolysis gas, must be carried out in a semi-enclosed, oxygen-deficient environment, the internal space is filled with complex and flammable / explosive pyrolysis gas. Fluctuations in the amount, composition, and calorific value of the input waste are unavoidable, leading to continuous fluctuations in the amount of pyrolysis gas produced. Under these conditions, achieving continuous and stable operation of the entire process is extremely difficult, and there are very few successful cases of continuous operation of such equipment, both domestically and internationally.

[0005] WO2014092092A1 discloses a magnetic pyrolysis device, which enables a low-temperature gasification process for pyrolysis and gasification of waste using magnetized air under a thermomagnetic magnetic field. Patent JP6223720B2 discloses a magnetic field pyrolysis furnace, which, during normal operation, achieves complete combustion of combustibles without fuel or electricity, producing only a small amount of ash. However, both patents primarily describe the principles and methods of magnetized pyrolysis and gasification under a thermomagnetic magnetic field, lacking effective methods for treating the gasified pyrolysis gas, and further neglecting process control methods.

[0006] CN105157032A discloses a magnetized pyrolysis device. The described process and low-temperature gasification principle under a thermomagnetic field are essentially the same as those in patent WO2014092092A1. However, it proposes a different process for treating the subsequent tail gas of the pyrolysis gas compared to WO2014092092A1. Specifically, after the low-temperature pyrolysis gasification chamber, the pyrolysis gas undergoes a second high-temperature pyrolysis before combustion. However, this patent still does not mention any control methods to ensure the continuous and stable operation of the entire process.

[0007] CN116221734A discloses a magnetized pyrolysis incineration device and its feed control method. This method collects pyrolysis gas parameters and adjusts the feed cycle and magnetized air volume based on parameter changes to control the operating load of the entire device, especially the magnetized pyrolysis gasification chamber. This represents a significant step forward in the practical application of thermomagnetic gasification technology. However, this patent does not address the load adjustment method for the high-temperature pyrolysis chamber. In actual operation, issues such as how to manage the load of the high-temperature pyrolysis chamber, and the discontinuous combustion of pyrolysis gas due to fluctuations in pyrolysis gas production, as well as substandard exhaust emissions, will still arise. If the pyrolysis gas cannot achieve continuous and complete combustion, exhaust emission standards are easily exceeded.

[0008] In actual operation, the amount of pyrolysis gas produced by the magnetized pyrolysis gasification chamber of the thermomagnetic gasification unit fluctuates due to factors such as fluctuations in the amount of waste input and changes in waste composition. This inevitably leads to changes in the operating conditions of the high-temperature pyrolysis chamber, significantly impacting the high-temperature pyrolysis of the pyrolysis gas and subsequent combustion. It may result in unstable or incomplete combustion of the pyrolysis gas at the outlet of the high-temperature pyrolysis chamber, especially during low-load operation and shutdown. In these cases, the amount of pyrolysis gas produced by the magnetized pyrolysis gasification chamber will be significantly lower than the expected design target under normal load. If the load of the high-temperature pyrolysis chamber is not effectively controlled, the high-temperature secondary pyrolysis and combustion process of the pyrolysis gas will be affected, leading to incomplete combustion. This, in turn, increases the pressure on subsequent environmental treatment facilities and makes it difficult to meet exhaust emission standards. Summary of the Invention

[0009] In view of this, the purpose of the present invention is to provide a method and system for adjusting the load of the high-temperature pyrolysis chamber of a thermomagnetic gasification device, which can cope with the fluctuation of the amount of pyrolysis gas generated from the magnetized pyrolysis gasification chamber, realize continuous, stable and effective further pyrolysis of the pyrolysis gas, and ensure continuous, sufficient and stable combustion, thereby avoiding the problem of substandard exhaust gas emissions caused by substandard high-temperature pyrolysis, incomplete combustion or even flameout.

[0010] The present invention discloses a method for adjusting the load of a high-temperature pyrolysis chamber in a thermomagnetic gasification apparatus, wherein the high-temperature pyrolysis chamber is used to further pyrolyze and combust the pyrolysis gas generated in the magnetized pyrolysis gasification chamber of the thermomagnetic gasification apparatus, and the method includes: The pyrolysis gas generated in the magnetized pyrolysis gasification chamber is introduced into at least one of the high-temperature pyrolysis chambers. The pyrolysis gas in each of the high-temperature pyrolysis chambers is heated, and the temperature of the pyrolysis gas after heating in each of the high-temperature pyrolysis chambers is monitored respectively. After heating, the pyrolysis gas is discharged from each of the high-temperature pyrolysis chambers and completes final combustion. The combustion status of the pyrolysis gas discharged from the high-temperature pyrolysis chambers is monitored. In response to the fact that the temperature of the pyrolysis gas after heating in any high-temperature pyrolysis chamber is not within the preset pyrolysis gas temperature range, the pyrolysis gas intake of the corresponding high-temperature pyrolysis chamber is adjusted or / and the heating power of the corresponding high-temperature pyrolysis chamber is adjusted to meet the preset pyrolysis gas temperature range. In response to the combustion conditions not meeting the expected state, fuel is added to the high-temperature pyrolysis chamber and / or the pyrolysis gas intake of the high-temperature pyrolysis chamber is increased to make the combustion conditions meet the expected state.

[0011] Furthermore, the step of replenishing fuel to the high-temperature pyrolysis chamber and / or increasing the pyrolysis gas intake of the high-temperature pyrolysis chamber in response to the combustion condition not meeting the expected state includes: When the pyrolysis gas generated by the magnetized pyrolysis gasification chamber is only introduced into one of the high-temperature pyrolysis chambers, in response to the combustion situation not meeting the expected state, fuel is added to the high-temperature pyrolysis chamber, the opening of the pyrolysis gas regulating valve of the high-temperature pyrolysis chamber is increased, or / and the pyrolysis gas production of the magnetized pyrolysis gasification chamber is increased, so that the combustion situation meets the expected state. When the pyrolysis gas generated by the magnetized pyrolysis gasification chamber is introduced into two or more of the high-temperature pyrolysis chambers, in response to the combustion conditions of some or all of the high-temperature pyrolysis chambers not meeting the expected state, fuel is added to the high-temperature pyrolysis chambers and / or the pyrolysis gas intake of some or all of the high-temperature pyrolysis chambers is increased to make the combustion conditions meet the expected state; wherein, increasing the pyrolysis gas intake of some of the high-temperature pyrolysis chambers means controlling the pyrolysis gas regulating valve of the high-temperature pyrolysis chambers whose combustion conditions do not meet the expected state to increase the opening, or / and reduce or even close the pyrolysis gas regulating valve of another part of the high-temperature pyrolysis chambers; increasing the pyrolysis gas intake of all the high-temperature pyrolysis chambers means increasing the pyrolysis gas production of the magnetized pyrolysis gasification chamber and / or controlling the pyrolysis gas regulating valve of all the high-temperature pyrolysis chambers to increase the opening.

[0012] Furthermore, the method also includes: The flue gas produced after the pyrolysis gas is burned is discharged to the exhaust gas treatment system; Obtain the flue gas temperature within the exhaust gas treatment system; In response to the flue gas temperature being higher than a preset flue gas temperature limit, the pyrolysis gas production rate of the magnetized pyrolysis gasification chamber is reduced or / and the opening of the pyrolysis gas regulating valve of each of the high-temperature pyrolysis chambers is reduced, so as to reduce the pyrolysis gas intake of the high-temperature pyrolysis chamber.

[0013] Furthermore, the step of adjusting the pyrolysis gas intake volume and / or adjusting the heating power of the corresponding high-temperature pyrolysis chamber in response to the pyrolysis gas temperature being outside the preset pyrolysis gas temperature range after heating in any high-temperature pyrolysis chamber includes: In response to the temperature of the pyrolysis gas after heating in any high-temperature pyrolysis chamber being lower than the lower limit of the preset pyrolysis gas temperature range, the heating power regulator of the corresponding high-temperature pyrolysis chamber is controlled to increase the heating power. In response to the pyrolysis gas temperature after heating in any high-temperature pyrolysis chamber being lower than the lower limit of the preset pyrolysis gas temperature range and the heating power regulator of the corresponding high-temperature pyrolysis chamber having adjusted the heating power to the maximum power, the pyrolysis gas production of the magnetized pyrolysis gasification chamber is reduced or / and the opening of the pyrolysis gas regulating valve of the corresponding high-temperature pyrolysis chamber is reduced to decrease the pyrolysis gas intake of the corresponding high-temperature pyrolysis chamber.

[0014] Furthermore, the step of adjusting the pyrolysis gas intake volume of the corresponding high-temperature pyrolysis chamber and / or adjusting the heating power of the corresponding high-temperature pyrolysis chamber to meet the preset pyrolysis gas temperature range in response to the pyrolysis gas temperature of any high-temperature pyrolysis chamber being outside the preset pyrolysis gas temperature range further includes: In response to the fact that the temperature of the pyrolysis gas after heating in any high-temperature pyrolysis chamber is higher than the upper limit of the preset pyrolysis gas temperature range and the flue gas temperature is not higher than the preset flue gas temperature limit, the pyrolysis gas production of the magnetized pyrolysis gasification chamber is increased or / and the opening of the pyrolysis gas regulating valve of the corresponding high-temperature pyrolysis chamber is increased to increase the pyrolysis gas intake of the corresponding high-temperature pyrolysis chamber. In response to the pyrolysis gas temperature after heating in any high-temperature pyrolysis chamber being higher than the upper limit of the preset pyrolysis gas temperature range, the flue gas temperature not being higher than the preset flue gas temperature limit, and the opening degree of the pyrolysis gas regulating valve of the corresponding high-temperature pyrolysis chamber reaching the maximum opening degree, the heating power regulator of the corresponding high-temperature pyrolysis chamber is controlled to reduce the heating power.

[0015] Furthermore, monitoring the combustion of the pyrolysis gas discharged from the high-temperature pyrolysis chamber includes: The controller receives flame information outside the outlet of each of the high-temperature pyrolysis chambers collected by the flame monitoring element, and / or the controller receives CO concentration information of the flue gas after the combustion of pyrolysis gas collected by the CO sensor. The controller determines whether the flame is normal based on the flame information, or / and the controller determines whether the CO concentration exceeds a predetermined threshold based on the CO concentration information; wherein, the flame information includes whether the flame is continuous, whether the flame is extinguished, and / or the flame temperature; if the flame is discontinuous, the flame is extinguished, and / or the flame temperature is lower than the preset threshold, the flame is determined to be abnormal, otherwise, the flame is determined to be normal. If the flame is abnormal or / and the CO concentration exceeds a predetermined threshold, the combustion condition is determined to be unsatisfactory; otherwise, the combustion condition is determined to be satisfactory.

[0016] The present invention provides a high-temperature pyrolysis chamber load regulation system for a thermomagnetic vaporization apparatus, comprising: At least one high-temperature pyrolysis chamber, the air inlet of which is connected to the magnetized pyrolysis gasification chamber of the thermomagnetic gasification device through a pyrolysis gas passage. The magnetized pyrolysis gasification chamber generates pyrolysis gas and transmits it to the high-temperature pyrolysis chamber through the pyrolysis gas passage. The high-temperature pyrolysis chamber is a chamber for heating the pyrolysis gas. After heating, the pyrolysis gas is discharged from the high-temperature pyrolysis chamber and then burned. The flue gas generated after combustion is discharged to the exhaust gas treatment system. Combustion monitoring elements are used to monitor the combustion status of each of the aforementioned high-temperature pyrolysis chambers; The first temperature sensor is used to monitor the temperature of the pyrolysis gas after heating in each of the high-temperature pyrolysis chambers. The second temperature sensor is used to collect the flue gas temperature in the exhaust gas treatment system. The pyrolysis gas regulating valve is used to regulate the pyrolysis gas intake of each high-temperature pyrolysis chamber; Heating power regulator, used to adjust the heating power of each high-temperature pyrolysis chamber; The afterburning system is used to replenish fuel to the high-temperature pyrolysis chamber; The controller is configured to: monitor the temperature of the pyrolysis gas after heating in each of the high-temperature pyrolysis chambers; monitor the combustion status of the pyrolysis gas discharged from the high-temperature pyrolysis chambers; in response to the temperature of the pyrolysis gas after heating in any high-temperature pyrolysis chamber not being within a preset pyrolysis gas temperature range, adjust the pyrolysis gas intake of the corresponding high-temperature pyrolysis chamber and / or adjust the heating power of the corresponding high-temperature pyrolysis chamber to meet the preset pyrolysis gas temperature range; in response to the combustion status not meeting the expected state, add fuel to the high-temperature pyrolysis chamber and / or increase the pyrolysis gas intake of the high-temperature pyrolysis chamber to make the combustion status meet the expected state; in response to the flue gas temperature being higher than a preset flue gas temperature limit, reduce the pyrolysis gas production of the magnetized pyrolysis gasification chamber and / or reduce the opening of the pyrolysis gas regulating valve of each of the high-temperature pyrolysis chambers to reduce the pyrolysis gas intake of the high-temperature pyrolysis chamber.

[0017] Furthermore, the afterburning system includes a fuel nozzle, a fuel pipeline, and a control valve; the fuel nozzle is used to inject fuel oil or fuel gas into the pyrolysis gas, and the fuel nozzle is located at the air inlet end of each of the high-temperature pyrolysis chambers or in the pyrolysis gas passage between the high-temperature pyrolysis chamber and the magnetized pyrolysis gasification chamber; the fuel pipeline is connected to the fuel nozzle and is used to supply fuel oil or fuel gas to the fuel nozzle; the control valve is used to control the on / off state of the fuel pipeline.

[0018] Furthermore, the afterburning system also includes an openable and closable protective cover disposed outside the fuel nozzle. The openable and closable protective cover has a protective posture and a working posture. When the openable and closable protective cover is in the protective posture, it can isolate the fuel nozzle from the pyrolysis gas. When the openable and closable protective cover is in the working posture, it can expose the fuel nozzle to the air inlet of the high-temperature pyrolysis chamber or to the pyrolysis gas passage.

[0019] Furthermore, an electric heating device is installed inside the high-temperature pyrolysis chamber, and the heating power regulator is an electric heating power regulator; the combustion monitoring device includes a flame monitoring element and / or a CO sensor, and the flame monitoring element is an ion probe, photoelectric eye, and / or a temperature detection element installed outside the outlet of the high-temperature pyrolysis chamber; the first temperature sensor is installed on the side of each of the high-temperature pyrolysis chambers near the outlet; the second temperature sensor is installed at the inlet of the exhaust gas treatment system or on the flue gas passage within the exhaust gas treatment system.

[0020] The beneficial effects of this invention are as follows: This invention can cope with fluctuations in the pyrolysis gas volume from the magnetized pyrolysis gasification chamber, achieving continuous, stable, and effective further pyrolysis of the pyrolysis gas. It also ensures that the temperature of the heated pyrolysis gas is sufficient for spontaneous combustion upon contact with oxygen, and by monitoring the combustion, it guarantees continuous, sufficient, and stable combustion of the heated pyrolysis gas. Furthermore, under low-load operating conditions and during shutdown, when the pyrolysis gas volume is significantly lower than the design level, continuous, sufficient, and stable combustion of the pyrolysis gas can be achieved by adding supplementary fuel, adjusting the pyrolysis gas intake volume of the high-temperature pyrolysis chamber, adjusting the heating power of the high-temperature pyrolysis chamber, and closing some of the pyrolysis gas regulating valves in the high-temperature pyrolysis chamber. This avoids problems such as substandard exhaust emissions due to insufficient high-temperature pyrolysis, incomplete combustion, or even flameout. Simultaneously, by detecting when the flue gas temperature exceeds a preset upper limit, it can identify situations where the pyrolysis gas production exceeds the design load value, and by reducing the pyrolysis gas intake volume, it ensures the stable and reliable operation of the entire system.

Detailed Implementation

[0023] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] Example 1: like Figure 1 As shown in this embodiment, a method for adjusting the load of the high-temperature pyrolysis chamber of a thermomagnetic gasification device is described. The high-temperature pyrolysis chamber 2 is used to further pyrolyze and combust the pyrolysis gas generated by the magnetized pyrolysis gasification chamber 1 of the thermomagnetic gasification device. The method includes: The pyrolysis gas generated in the magnetized pyrolysis gasification chamber 1 is introduced into a high-temperature pyrolysis chamber 2; The pyrolysis gas in the high-temperature pyrolysis chamber 2 is heated, and the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 is monitored. After heating, the pyrolysis gas is discharged from the high-temperature pyrolysis chamber 2 and completes final combustion. The combustion status of the pyrolysis gas discharged from the high-temperature pyrolysis chamber 2 is monitored. In response to the fact that the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 is not within the preset pyrolysis gas temperature range, the pyrolysis gas intake of the high-temperature pyrolysis chamber 2 is adjusted or / and the heating power of the high-temperature pyrolysis chamber 2 is adjusted to meet the preset pyrolysis gas temperature range. In response to the combustion conditions not meeting the expected state, fuel is added to the high-temperature pyrolysis chamber 2, the pyrolysis gas intake of the high-temperature pyrolysis chamber 2 is increased, and / or the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 is increased, so that the combustion conditions meet the expected state; wherein, increasing the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 can be achieved by increasing the material input or air intake of the magnetized pyrolysis gasification chamber 1.

[0025] The high-temperature pyrolysis chamber 2 heats the pyrolysis gas inside (usually to above 600°C). After heating, the pyrolysis gas is discharged from the outlet of the high-temperature pyrolysis chamber 2. After contacting oxygen, the discharged pyrolysis gas is spontaneously combusted (the contact of the heated pyrolysis gas with oxygen can be achieved by the heated pyrolysis gas being discharged directly from the outlet of the high-temperature pyrolysis chamber 2 and coming into direct contact with the outside atmosphere, or by introducing sufficient oxygen to the outlet of the high-temperature pyrolysis chamber 2 through an oxygen supply device). This further pyrolysis and combustion of the pyrolysis gas generated by the magnetized pyrolysis gasification chamber 1 of the thermomagnetic gasification device are achieved. During the above-mentioned operation, by monitoring the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2, any abnormalities are detected and the pyrolysis gas intake of the high-temperature pyrolysis chamber 2 is adjusted in real time or / and the heating power of the high-temperature pyrolysis chamber 2 is adjusted. This can cope with fluctuations in the amount of pyrolysis gas from the magnetized pyrolysis gasification chamber 1, achieving continuous, stable, and effective further pyrolysis of the pyrolysis gas. It can also ensure that the temperature of the pyrolysis gas after heating is sufficient for spontaneous combustion upon contact with oxygen. Furthermore, by monitoring the combustion situation and detecting any abnormalities, the afterburning system 54 is activated to supplement the fuel quantity or / and increase the temperature of the high-temperature pyrolysis chamber 2. By increasing the pyrolysis gas intake and / or increasing the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1, it is possible to ensure that the pyrolysis gas can continue to burn sufficiently and stably after heating. In addition, when the pyrolysis gas volume is significantly lower than the design level under low load operation conditions and during furnace shutdown, the continuous, sufficient and stable combustion of the pyrolysis gas can be achieved by supplementing the fuel volume, adjusting the pyrolysis gas intake of the high-temperature pyrolysis chamber 2, increasing the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1, and adjusting the heating power of the high-temperature pyrolysis chamber 2. This avoids the problem of substandard exhaust gas emissions caused by substandard high-temperature pyrolysis, incomplete combustion or even flameout.

[0026] It is worth noting that if the combustion conditions do not meet expectations, the measures adopted may be one or more of the following: adding fuel to the high-temperature pyrolysis chamber 2, increasing the opening of the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2, and increasing the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1. The priority of each measure can be set according to actual needs. For example: If the combustion condition does not meet the expected state, the measures adopted can be to first control the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 to increase the opening degree. If the combustion condition still does not meet the expected state after reaching the maximum set opening degree, fuel can be added to the high-temperature pyrolysis chamber 2. If the combustion condition still does not meet the expected state after adding fuel, the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 can be increased. For another example, if the combustion condition does not meet the expected state, the measures adopted can also be to simultaneously control the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 to increase the opening degree, add fuel to the high-temperature pyrolysis chamber 2, and increase the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1. For yet another example, if the combustion condition does not meet the expected state, the measures adopted can also be to first control the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 to increase the opening degree. If the expected state is still not met, the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 can be increased. If the expected state is still not met, fuel can be added to the high-temperature pyrolysis chamber 2. It is worth further explaining that if the measures taken in response to the combustion situation not meeting the expected state include "increasing the opening of the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2", priority should be given to ensuring that the flue gas temperature is not higher than the preset flue gas temperature limit and that the pyrolysis gas temperature after heating in the high-temperature pyrolysis chamber 2 is within the preset pyrolysis gas temperature range. That is, only when the flue gas temperature is not higher than the preset flue gas temperature limit and the pyrolysis gas temperature after heating in the high-temperature pyrolysis chamber 2 is within the preset pyrolysis gas temperature range will the measure of increasing the opening of the pyrolysis gas regulating valve 53 be taken in response to the combustion situation not meeting the expected state.

[0027] like Figure 2 As shown, in this embodiment, the method further includes: The flue gas produced after the pyrolysis gas is burned is discharged to the exhaust gas treatment system 4; Obtain the flue gas temperature within the exhaust gas treatment system 4; In response to the flue gas temperature being higher than the preset flue gas temperature limit, the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 is reduced or / and the opening of the pyrolysis gas regulating valve of each of the high-temperature pyrolysis chambers is reduced, so as to reduce the pyrolysis gas intake of the high-temperature pyrolysis chamber 2.

[0028] If the flue gas temperature exceeds the preset flue gas temperature limit, it indicates that the amount of pyrolysis gas introduced into the high-temperature pyrolysis chamber 2 is excessive. The further pyrolysis and combustion processing capacity of the high-temperature pyrolysis chamber 2 has exceeded its load. Therefore, it is necessary to reduce the pyrolysis gas production rate of the magnetized pyrolysis gasification chamber 1 and / or reduce the opening of the pyrolysis gas regulating valve 53 of each high-temperature pyrolysis chamber to reduce the pyrolysis gas intake of the high-temperature pyrolysis chamber 2. In other words, when the flue gas temperature exceeds the preset flue gas temperature limit, the situation of pyrolysis gas exceeding the design load is identified. By reducing the pyrolysis gas production rate of the magnetized pyrolysis gasification chamber and / or reducing the opening of the pyrolysis gas regulating valve of each high-temperature pyrolysis chamber, the pyrolysis gas intake of the high-temperature pyrolysis chamber is reduced to achieve stable and reliable operation of the entire system.

[0029] In this embodiment, in response to the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 not being within the preset pyrolysis gas temperature range, the pyrolysis gas intake volume of the high-temperature pyrolysis chamber 2 is adjusted or / and the heating power of the high-temperature pyrolysis chamber 2 is adjusted to meet the preset pyrolysis gas temperature range, including: In response to the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 being lower than the lower limit of the preset pyrolysis gas temperature range, the heating power regulator 55 of the high-temperature pyrolysis chamber 2 is controlled to increase the heating power. In response to the fact that the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 is lower than the lower limit of the preset pyrolysis gas temperature range and the heating power regulator 55 of the high-temperature pyrolysis chamber 2 has adjusted the heating power to the maximum power, the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 is reduced or / and the opening of the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 is reduced, so as to reduce the pyrolysis gas intake of the high-temperature pyrolysis chamber 2.

[0030] Specifically, the heating power of the high-temperature pyrolysis chamber 2 is divided into multiple levels from low to high, including at least level one (minimum power), level two, ... N levels (up to maximum power). The heating power regulator 55 can adjust the heating power of the high-temperature pyrolysis chamber 2 to a specified level. The pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 can be reduced by decreasing the material input or air intake of the magnetized pyrolysis gasification chamber 1. The pyrolysis gas regulating valve 53 has different opening levels, such as 0% (completely closed), 20%, 50%, 80%, and 100% (completely open). Different opening levels can change the pyrolysis gas intake of the high-temperature pyrolysis chamber 22. It is worth noting that the above-mentioned multi-level heating power and the levels of the pyrolysis gas regulating valve 53 are only examples and not limitations; other technical solutions can also be used. The following provides a further example of this embodiment: The temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 is acquired at regular intervals. When the Mth acquired temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 is lower than the lower limit of the preset pyrolysis gas temperature range, if the heating power of the high-temperature pyrolysis chamber 2 has not reached its maximum power, the heating power is adjusted first. The heating power regulator 55 adjusts the heating power of the high-temperature pyrolysis chamber 2 to a higher level (e.g., from level two to level three). If, after increasing the heating power, the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 is still lower than the lower limit of the preset pyrolysis gas temperature range, the heating power continues to be adjusted. The heating power regulator 55 adjusts the heating power of the high-temperature pyrolysis chamber 2 to a higher level (e.g., from level three to level four) until the heating power reaches its maximum power. If the heating power has reached its maximum, it means that adjusting the heating power alone cannot guarantee that the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 will meet the standard. In this case, the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 is reduced, and / or the opening of the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 is reduced, thereby reducing the pyrolysis gas intake of the high-temperature pyrolysis chamber 2. Taking the reduction of the opening of the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 as an example, when the outlet flue gas temperature obtained in the M+2th time is still lower than the lower limit of the preset temperature range, the heating power has reached its maximum. At this time, it is necessary to control the opening of the pyrolysis gas regulating valve 53 to reduce (e.g., from 80% opening to 50% opening) to reduce the pyrolysis gas intake of the high-temperature pyrolysis chamber 2. If the pyrolysis gas temperature obtained in the next time after reducing the opening of the pyrolysis gas regulating valve 53 is still lower than the lower limit of the preset temperature range, the opening of the pyrolysis gas regulating valve 53 is further reduced until the minimum set opening of the pyrolysis gas regulating valve 53 is reached. This control logic, which prioritizes adjusting the heating power when the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 is low, without changing the opening of the pyrolysis gas regulating valve 53, delays the timing of reducing the opening of the pyrolysis gas regulating valve 53. This ensures that the pyrolysis gas intake of the high-temperature pyrolysis chamber 2 is maintained at a high level, thereby balancing the need for continuous and stable further pyrolysis and combustion of the pyrolysis gas, as well as the efficiency of pyrolysis gas treatment.

[0031] In this embodiment, in response to the pyrolysis gas temperature after heating in the high-temperature pyrolysis chamber 2 not being within the preset pyrolysis gas temperature range, the pyrolysis gas intake volume of the high-temperature pyrolysis chamber 2 is adjusted or / and the heating power of the high-temperature pyrolysis chamber 2 is adjusted to meet the preset pyrolysis gas temperature range, and the method further includes: In response to the fact that the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 is higher than the upper limit of the preset pyrolysis gas temperature range and the flue gas temperature is not higher than the preset flue gas temperature limit, the pyrolysis gas production rate of the magnetized pyrolysis gasification chamber 1 is increased or / and the opening degree of the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 is increased, so as to increase the pyrolysis gas intake rate of the high-temperature pyrolysis chamber 2; the pyrolysis gas production rate of the magnetized pyrolysis gasification chamber 1 can be increased by increasing the material input or air intake of the magnetized pyrolysis gasification chamber 1; In response to the fact that the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 is higher than the upper limit of the preset pyrolysis gas temperature range, the flue gas temperature is not higher than the preset flue gas temperature limit, and the opening degree of the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 reaches the maximum set opening degree, the heating power regulator 55 of the high-temperature pyrolysis chamber 2 is controlled to reduce the heating power.

[0032] When the flue gas temperature is higher than the preset flue gas temperature limit, the pyrolysis gas intake of the high-temperature pyrolysis chamber 2 needs to be reduced. The priority of meeting the flue gas temperature standard is higher than the priority of meeting the pyrolysis gas temperature standard after heating in the high-temperature pyrolysis chamber 2. Therefore, only after both conditions are met—that the pyrolysis gas temperature after heating in the high-temperature pyrolysis chamber 2 is higher than the upper limit of the preset pyrolysis gas temperature range and that the flue gas temperature is not higher than the preset flue gas temperature limit—will the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 be controlled to increase its opening to increase the pyrolysis gas intake of the high-temperature pyrolysis chamber 2. Meanwhile, when the pyrolysis gas temperature after heating in the high-temperature pyrolysis chamber 2 is too high, the opening of the pyrolysis gas regulating valve 53 is increased first. Only when the opening of the pyrolysis gas regulating valve 53 reaches its maximum opening is the heating power regulator 55 of the high-temperature pyrolysis chamber 2 controlled to reduce the heating power. This control logic, which prioritizes increasing the opening of the pyrolysis gas regulating valve 53 when the pyrolysis gas temperature after heating in the high-temperature pyrolysis chamber 2 is high, without changing the heating power of the heating power regulator 55, allows the timing of increasing the opening of the pyrolysis gas regulating valve 53 to be advanced. This ensures that the pyrolysis gas intake of the high-temperature pyrolysis chamber 2 is maintained at a high level, thereby balancing the need for continuous and stable further pyrolysis and combustion to meet standards, as well as the pyrolysis gas processing efficiency.

[0033] The following provides a further example of this embodiment: The temperature of the pyrolysis gas and the flue gas after heating in the high-temperature pyrolysis chamber 2 are acquired at regular intervals. When the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 is higher than the upper limit of the preset pyrolysis gas temperature range and the flue gas temperature is not higher than the preset flue gas temperature limit, if the opening of the pyrolysis gas regulating valve 53 has not reached the maximum set opening, it is necessary to control the opening of the pyrolysis gas regulating valve 53 to increase (e.g., from 50% to 80%) to increase the pyrolysis gas intake of the high-temperature pyrolysis chamber 2. If the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2 is still higher than the upper limit of the preset temperature range and the flue gas temperature is not higher than the preset flue gas temperature limit after increasing the opening of the pyrolysis gas regulating valve 53, the opening of the pyrolysis gas regulating valve 53 is continued to be increased until the pyrolysis gas regulating valve 53 reaches the maximum set opening. If the pyrolysis gas regulating valve 53 is already at its maximum set opening, and the temperature of the heated pyrolysis gas is still higher than the upper limit of the preset temperature range, it means that simply adjusting the pyrolysis gas intake is no longer sufficient to ensure that the temperature of the heated pyrolysis gas in the high-temperature pyrolysis chamber 2 meets the standard. In this case, the heating power regulator 55 is controlled to reduce the heating power of the high-temperature pyrolysis chamber 2. For example, if the outlet flue gas temperature obtained in the P+2th time is still higher than the upper limit of the preset temperature range, the opening of the pyrolysis gas regulating valve 53 is already at its maximum set opening. In this case, the heating power regulator 55 needs to be controlled to reduce the heating power of the high-temperature pyrolysis chamber 2 (e.g., from level four to level three). If the temperature of the heated pyrolysis gas in the high-temperature pyrolysis chamber 2 is still higher than the upper limit of the preset temperature range after reducing the heating power of the high-temperature pyrolysis chamber 2, the heating power of the high-temperature pyrolysis chamber 2 is further reduced until the heating power is at its minimum.

[0034] In this embodiment, monitoring the combustion of the pyrolysis gas discharged from the high-temperature pyrolysis chamber 2 includes: The controller 56 receives flame information outside the outlet of the high-temperature pyrolysis chamber 2 collected by the flame monitoring element 51, and / or receives CO concentration information of the flue gas after the combustion of pyrolysis gas collected by the CO sensor 58. The controller 56 determines whether the flame is normal based on the flame information, or / and the controller determines whether the CO concentration exceeds a predetermined threshold based on the CO concentration information; wherein, the flame information includes whether the flame is continuous, whether the flame is extinguished, and / or the flame temperature; if the flame is discontinuous, the flame is extinguished, and / or the flame temperature is lower than the preset threshold, the flame is determined to be abnormal, otherwise, the flame is determined to be normal. If the flame is abnormal or / and the CO concentration exceeds a predetermined threshold, the combustion condition is determined to be unsatisfactory; otherwise, the combustion condition is determined to be satisfactory.

[0035] Specifically, this includes the following three situations: If only the flame monitoring element 51 is installed and the CO sensor 58 is not installed, the combustion status of the pyrolysis gas discharged from the high-temperature pyrolysis chamber 2 is monitored, including the following steps: the controller 56 receives the flame information collected by the flame monitoring element 51 outside the outlet of the high-temperature pyrolysis chamber 2 and determines whether the flame is normal based on the flame information; if the flame is discontinuous, extinguished, or / and the flame temperature is lower than a preset threshold, the flame is judged to be abnormal and the combustion status is judged not to meet the expected state; if the flame is continuous, the flame is burning normally and has not extinguished, and the flame temperature is not lower than the preset threshold, the combustion status is judged to meet the expected state.

[0036] If only the CO sensor 58 is installed and the flame monitoring element 51 is not installed, the combustion status of the pyrolysis gas discharged from the high-temperature pyrolysis chamber 2 is monitored, including the following steps: the controller determines whether the CO concentration exceeds a predetermined threshold based on the CO concentration information; if the CO concentration exceeds the predetermined threshold, it is determined that the combustion status does not meet the expected state; if the CO concentration does not exceed the predetermined threshold, it is determined that the combustion status meets the expected state. The predetermined threshold for CO concentration is adaptively set according to the requirements of relevant environmental protection laws and regulations on carbon monoxide emissions in different countries or regions.

[0037] If both a flame monitoring element 51 and a CO sensor 58 are installed, the combustion status of the pyrolysis gas discharged from the high-temperature pyrolysis chamber 2 is monitored, including the following steps: the controller 56 receives flame information collected by the flame monitoring element 51 outside the outlet of the high-temperature pyrolysis chamber 2, and the controller receives CO concentration information of the flue gas after the combustion of the pyrolysis gas collected by the CO sensor 58; the controller 56 determines whether the flame is normal based on the flame information, and the controller determines whether the CO concentration exceeds a predetermined threshold based on the CO concentration information; if the flame is discontinuous, the flame is extinguished, or / and the CO concentration exceeds the predetermined threshold, the combustion status is determined to be unsatisfactory; if the flame is continuous, the flame is burning normally without extinguishing, and the CO concentration does not exceed the predetermined threshold, the combustion status is determined to be satisfactory.

[0038] The flame monitoring element 51 is an ion probe, photoelectric eye, and / or temperature detection element installed outside the pyrolysis gas outlet of the high-temperature pyrolysis chamber 2. The ion probe, photoelectric eye, and temperature detection element are all existing technologies and are commonly used flame monitoring elements 51 in burner flameout protection devices. The ion probe can detect the flame state by utilizing the conductivity principle of flame plasma. The photoelectric eye can detect the flame state by utilizing the light generated during flame combustion through the photoelectric conversion principle. The temperature detection element detects the flame state by detecting whether the flame temperature is lower than a preset threshold.

[0039] The CO sensor 58 can be installed inside the exhaust gas treatment system 4 or in the flue gas passage between the exhaust gas treatment system 4 and the high-temperature pyrolysis chamber 2.

[0040] Example 2: like Figure 3 and Figure 4 As shown, the high-temperature pyrolysis chamber 2 load adjustment system of the thermomagnetic vaporization device in this embodiment is used to implement the high-temperature pyrolysis chamber load adjustment method of the thermomagnetic vaporization device in the first embodiment above. The system includes: A high-temperature pyrolysis chamber 2 is provided. The air inlet of the high-temperature pyrolysis chamber 2 is connected to the magnetized pyrolysis gasification chamber 1 of the thermomagnetic gasification device through a pyrolysis gas passage 3. The magnetized pyrolysis gasification chamber 1 generates pyrolysis gas and transmits it to the high-temperature pyrolysis chamber 2 through the pyrolysis gas passage 3. The high-temperature pyrolysis chamber 2 is a chamber used to heat the pyrolysis gas. After heating, the pyrolysis gas is discharged from the high-temperature pyrolysis chamber 2 and burned. The flue gas generated after combustion is discharged to the exhaust gas treatment system 4. The magnetized pyrolysis gasification chamber 1 includes a gasification chamber body 11, a feeding mechanism 12 located outside the gasification chamber body 11, an ash removal mechanism 13 located below the gasification chamber body 11, a gasification chamber pyrolysis gas outlet 14 located on the gasification chamber body 11 for connection with the pyrolysis gas passage 3, an air magnetization device 15 located outside the gasification chamber body 11, and an air distribution duct 16 located inside the gasification chamber body 11. The gasification chamber body 11 can pyrolyze organic waste or medical waste entering the gasification chamber body 11 and generate pyrolysis gas, and discharge the pyrolysis gas into the pyrolysis gas passage 3. Then, the pyrolysis gas enters the high temperature pyrolysis chamber 2 through the pyrolysis gas passage 3 for further secondary pyrolysis and combustion. The gas after secondary pyrolysis and combustion is then discharged to the exhaust gas treatment system 4. A combustion flame monitoring device is used to monitor the combustion status of the high-temperature pyrolysis chamber 2. The combustion flame monitoring device includes a flame monitoring element and / or a CO sensor 58. The flame monitoring element 51 is an ion probe, photoelectric eye and / or a temperature detection element installed outside the pyrolysis gas outlet of the high-temperature pyrolysis chamber 2. The CO sensor 58 can be installed inside the exhaust gas treatment system 4 or in the flue gas channel between the exhaust gas treatment system 4 and the high-temperature pyrolysis chamber 2. The first temperature sensor 52 is used to monitor the temperature of the pyrolysis gas after the high-temperature pyrolysis chamber 2 is heated. The first temperature sensor is located on the side of the high-temperature pyrolysis chamber near the outlet. The second temperature sensor 57 is used to collect the flue gas temperature in the exhaust gas treatment system 4. The second temperature sensor is set at the inlet of the exhaust gas treatment system 4 or on the flue gas passage in the exhaust gas treatment system 4. The pyrolysis gas regulating valve 53, located at the air inlet of the high-temperature pyrolysis chamber 2, is used to regulate the pyrolysis gas intake of the high-temperature pyrolysis chamber 2. The heating power regulator 55 installed on the high-temperature pyrolysis chamber 2 is used to adjust the heating power of the high-temperature pyrolysis chamber 2. The afterburning system 54 is used to replenish fuel to the high-temperature pyrolysis chamber 2; The controller 56 is used for: monitoring the temperature of the pyrolysis gas after heating in the high-temperature pyrolysis chamber 2; monitoring the combustion status of the pyrolysis gas discharged from the high-temperature pyrolysis chamber 2; adjusting the pyrolysis gas intake volume of the high-temperature pyrolysis chamber 2 and / or adjusting the heating power of the corresponding high-temperature pyrolysis chamber 2 in response to the pyrolysis gas temperature after heating in the high-temperature pyrolysis chamber 2 not being within the preset pyrolysis gas temperature range, so as to meet the preset pyrolysis gas temperature range; adding fuel to the high-temperature pyrolysis chamber 2 and / or increasing the pyrolysis gas intake volume of the high-temperature pyrolysis chamber 2 in response to the combustion status not meeting the expected state, so as to make the combustion status meet the expected state; and reducing the pyrolysis gas production volume of the magnetized pyrolysis gasification chamber 1 and / or reducing the opening degree of the pyrolysis gas regulating valve 53 of each high-temperature pyrolysis chamber 2 in response to the flue gas temperature being higher than the preset flue gas temperature limit, so as to reduce the pyrolysis gas intake volume of the high-temperature pyrolysis chamber 2.

[0041] In this embodiment, the afterburning system 54 includes a fuel nozzle, a fuel pipeline, and a control valve. The fuel nozzle is used to inject fuel oil or fuel gas into the pyrolysis gas. The fuel nozzle is located at the air inlet of each high-temperature pyrolysis chamber 2 or in the pyrolysis gas passage 3 between the high-temperature pyrolysis chamber 2 and the magnetized pyrolysis gasification chamber 1. The fuel pipeline is connected to the fuel nozzle and is used to supply fuel oil or fuel gas to the fuel nozzle. The control valve is used to control the on / off state of the fuel pipeline.

[0042] In this embodiment, the afterburning system 54 also includes an openable and closable protective cover disposed outside the fuel nozzle. The openable and closable protective cover has a protective posture and a working posture. When the openable and closable protective cover is in the protective posture, it can isolate the fuel nozzle from the pyrolysis gas. When the openable and closable protective cover is in the working posture, it can expose the fuel nozzle to the air inlet of the high-temperature pyrolysis chamber 2 or to the pyrolysis gas passage 3.

[0043] In this embodiment, an electric heating device is installed in the high-temperature pyrolysis chamber 2, and the heating power regulator 55 is an electric heating power regulator 55.

[0044] Example 3: like Figure 5 As shown in this embodiment, a method for adjusting the load of the high-temperature pyrolysis chamber of a thermomagnetic gasification device is described. The high-temperature pyrolysis chamber 2 is used to further pyrolyze and combust the pyrolysis gas generated by the magnetized pyrolysis gasification chamber 1 of the thermomagnetic gasification device. The method includes: The pyrolysis gas generated in the magnetized pyrolysis gasification chamber 1 is introduced into three high-temperature pyrolysis chambers 2 (this embodiment uses three high-temperature pyrolysis chambers 2 in parallel for illustration; in actual applications, the number of high-temperature pyrolysis chambers 2 can also be other, such as two, four, five, six, etc.). The pyrolysis gas in the three high-temperature pyrolysis chambers 2 is heated, and the temperature of the pyrolysis gas in the three high-temperature pyrolysis chambers 2 after heating is monitored respectively. After heating, the pyrolysis gas is discharged from each high-temperature pyrolysis chamber 2 and completes final combustion. The combustion status of the pyrolysis gas discharged from the high-temperature pyrolysis chamber 2 is monitored. In response to the fact that the temperature of the pyrolysis gas after heating in any high-temperature pyrolysis chamber 2 is not within the preset pyrolysis gas temperature range, the pyrolysis gas intake of the corresponding high-temperature pyrolysis chamber 2 is adjusted or / and the heating power of the corresponding high-temperature pyrolysis chamber 2 is adjusted to meet the preset pyrolysis gas temperature range. The pyrolysis gas generated in the magnetized pyrolysis gasification chamber 1 is introduced into three high-temperature pyrolysis chambers 2. Since there are two or more such chambers, in response to a situation where the combustion conditions in some or all of the high-temperature pyrolysis chambers 2 do not meet expectations, fuel is added to the high-temperature pyrolysis chambers 2, and / or the pyrolysis gas intake of some or all of the high-temperature pyrolysis chambers 2 is increased, so that the combustion conditions meet expectations. Increasing the pyrolysis gas intake of some high-temperature pyrolysis chambers 2 means increasing the opening of the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 where the combustion conditions do not meet expectations, or / or decreasing or even closing the pyrolysis gas regulating valve 53 of another high-temperature pyrolysis chamber 2. Increasing the pyrolysis gas intake of all high-temperature pyrolysis chambers 2 means increasing the pyrolysis gas production of the magnetized pyrolysis gasification chamber, or / or increasing the opening of the pyrolysis gas regulating valve 53 of all high-temperature pyrolysis chambers.

[0045] The high-temperature pyrolysis chamber 2 heats the pyrolysis gas inside (usually to above 600°C). After heating, the pyrolysis gas is discharged from the outlet of the high-temperature pyrolysis chamber 2. After contacting oxygen, the discharged pyrolysis gas is spontaneously combusted (the contact of the heated pyrolysis gas with oxygen can be achieved by the heated pyrolysis gas directly contacting the external atmosphere after being discharged from the outlet of the high-temperature pyrolysis chamber 2, or by introducing sufficient oxygen to the outlet of the high-temperature pyrolysis chamber 2 through an oxygen supply device). This further pyrolysis and combustion of the pyrolysis gas generated by the magnetized pyrolysis gasification chamber 1 of the thermomagnetic gasification device are achieved.

[0046] During the above-mentioned operation, the temperature of the pyrolysis gas after heating in each high-temperature pyrolysis chamber 2 is monitored. If any abnormality is detected, the pyrolysis gas intake of the corresponding high-temperature pyrolysis chamber 2 is adjusted in real time or / and the heating power of the high-temperature pyrolysis chamber 2 is adjusted. This can cope with the fluctuation of the pyrolysis gas volume from the magnetized pyrolysis gasification chamber 1, realize the continuous, stable and effective further pyrolysis of the pyrolysis gas, and ensure that the temperature of the pyrolysis gas after heating is sufficient to cause spontaneous combustion upon contact with oxygen.

[0047] Furthermore, by monitoring the combustion status of each high-temperature pyrolysis chamber 2, if abnormal combustion is detected in some or all of the high-temperature pyrolysis chambers 2, the afterburning system 54 is immediately activated to supplement the fuel supply, and / or increase the pyrolysis gas intake of some or all of the high-temperature pyrolysis chambers 2, so that the combustion status meets the expected state. Increasing the pyrolysis gas intake of some high-temperature pyrolysis chambers 2 means increasing the opening of the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chambers 2 where the combustion status does not meet the expected state, and / or decreasing or even closing the pyrolysis gas regulating valve of another part of the high-temperature pyrolysis chambers 2; increasing the pyrolysis gas intake of all the high-temperature pyrolysis chambers means increasing the pyrolysis gas production of the magnetized pyrolysis gasification chamber or / or increasing the opening of the pyrolysis gas regulating valve of all high-temperature pyrolysis chambers. Among these, activating the afterburning system 54 to supplement the fuel supply can promote combustion. Specifically, adjusting or even closing the pyrolysis gas regulating valve 53 of another part of the high-temperature pyrolysis chamber 2 can change the pyrolysis gas flow distribution of each high-temperature pyrolysis chamber 2, thereby increasing the pyrolysis gas flow of the high-temperature pyrolysis chamber 2 where the combustion conditions do not meet expectations, thus increasing the pyrolysis gas intake of the high-temperature pyrolysis chamber 2 where the combustion conditions do not meet expectations; for example: when Figure 7 If the combustion condition of the rightmost high-temperature pyrolysis chamber 2 does not meet expectations, the pyrolysis gas regulating valve 53 of another high-temperature pyrolysis chamber 2 can be closed. This allows the pyrolysis gas originally distributed to the three high-temperature pyrolysis chambers 2 to be distributed only to the two high-temperature pyrolysis chambers 2 whose pyrolysis gas regulating valve 53 is still open, thereby increasing the pyrolysis gas intake of the two high-temperature pyrolysis chambers 2 whose pyrolysis gas regulating valve 53 is still open. For example, when Figure 7 If the combustion condition of the rightmost high-temperature pyrolysis chamber 2 does not meet expectations, the opening of the pyrolysis gas regulating valves 53 of the two left-hand high-temperature pyrolysis chambers 2 can be reduced, thus decreasing the pyrolysis gas flow rate of the two left-hand high-temperature pyrolysis chambers and increasing the pyrolysis gas flow rate of the rightmost high-temperature pyrolysis chamber 2, thereby increasing the pyrolysis gas intake of the rightmost high-temperature pyrolysis chamber 2. Specifically, increasing the opening of the pyrolysis gas regulating valves 53 of the high-temperature pyrolysis chamber 2 where the combustion condition does not meet expectations increases the pyrolysis gas intake of the high-temperature pyrolysis chamber 2 where combustion is not as expected. For example, when... Figure 7 If the combustion condition of the rightmost high-temperature pyrolysis chamber 2 does not meet expectations, then it can be controlled. Figure 7 The pyrolysis gas regulating valve 53 in the rightmost high-temperature pyrolysis chamber 2 increases its opening, thereby enabling... Figure 7 The pyrolysis gas intake of the rightmost high-temperature pyrolysis chamber 2 is increased.

[0048] In summary, by adding fuel to the high-temperature pyrolysis chamber 2 and / or increasing the pyrolysis gas intake of the chamber 2 by a large or small amount, the combustion conditions can meet the expected requirements, enabling continuous, sufficient, and stable combustion of the pyrolysis gas and avoiding problems such as substandard exhaust emissions due to inadequate high-temperature pyrolysis, incomplete combustion, or even flameout.

[0049] It is worth noting that if the combustion conditions do not meet expectations, the measures adopted may be one or more of the following: adding fuel to the high-temperature pyrolysis chamber 2, increasing the opening of the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2, and increasing the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1. The priority of each measure can be set according to actual needs. For example: If the combustion condition does not meet the expected state, the measures adopted can be to first control the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 to increase the opening degree. If the combustion condition still does not meet the expected state after reaching the maximum set opening degree, fuel can be added to the high-temperature pyrolysis chamber 2. If the combustion condition still does not meet the expected state after adding fuel, the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 can be increased. For another example, if the combustion condition does not meet the expected state, the measures adopted can also be to simultaneously control the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 to increase the opening degree, add fuel to the high-temperature pyrolysis chamber 2, and increase the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1. For yet another example, if the combustion condition does not meet the expected state, the measures adopted can also be to first control the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 to increase the opening degree. If the expected state is still not met, the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 can be increased. If the expected state is still not met, fuel can be added to the high-temperature pyrolysis chamber 2. It is worth further explaining that if the measures taken in response to the combustion situation not meeting the expected state include "increasing the opening of the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2", priority should be given to ensuring that the flue gas temperature is not higher than the preset flue gas temperature limit and that the pyrolysis gas temperature after heating in the high-temperature pyrolysis chamber 2 is within the preset pyrolysis gas temperature range. That is, only when the flue gas temperature is not higher than the preset flue gas temperature limit and the pyrolysis gas temperature after heating in the high-temperature pyrolysis chamber 2 is within the preset pyrolysis gas temperature range will the measure of increasing the opening of the pyrolysis gas regulating valve 53 be taken in response to the combustion situation not meeting the expected state.

[0050] like Figure 6 As shown, in this embodiment, the method further includes: The flue gas produced after the pyrolysis gas is burned is discharged to the exhaust gas treatment system 4; Obtain the flue gas temperature within the exhaust gas treatment system 4; In response to a flue gas temperature exceeding a preset flue gas temperature limit, the pyrolysis gas production rate of the magnetized pyrolysis gasification chamber 1 is reduced, and / or the opening degree of the pyrolysis gas regulating valve 53 of each high-temperature pyrolysis chamber 2 is reduced, thereby reducing the pyrolysis gas intake of the high-temperature pyrolysis chamber 2. When the flue gas temperature exceeds the preset flue gas temperature limit, a situation where the pyrolysis gas volume exceeds the design load is identified. The pyrolysis gas production rate of the magnetized pyrolysis gasification chamber is reduced, and / or the opening degree of the pyrolysis gas regulating valve of each of the high-temperature pyrolysis chambers is reduced, thereby reducing the pyrolysis gas intake of the high-temperature pyrolysis chambers to achieve stable and reliable operation of the entire system.

[0051] In this embodiment, in response to the pyrolysis gas temperature after heating in any high-temperature pyrolysis chamber 2 being outside the preset pyrolysis gas temperature range, the pyrolysis gas intake volume of the corresponding high-temperature pyrolysis chamber 2 is adjusted or / and the heating power of the corresponding high-temperature pyrolysis chamber 2 is adjusted to meet the preset pyrolysis gas temperature range, including: In response to the temperature of the pyrolysis gas after heating in any high-temperature pyrolysis chamber 2 being lower than the lower limit of the preset pyrolysis gas temperature range, the heating power regulator 55 of the corresponding high-temperature pyrolysis chamber 2 is controlled to increase the heating power. In response to the pyrolysis gas temperature after heating in any high-temperature pyrolysis chamber 2 being lower than the lower limit of the preset pyrolysis gas temperature range and the heating power regulator 55 of the corresponding high-temperature pyrolysis chamber 2 having adjusted the heating power to the maximum power, the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 is reduced or / and the opening of the pyrolysis gas regulating valve 53 of the corresponding high-temperature pyrolysis chamber 2 is reduced to decrease the pyrolysis gas intake of the corresponding high-temperature pyrolysis chamber 2.

[0052] In this embodiment, in response to the pyrolysis gas temperature after heating in any high-temperature pyrolysis chamber 2 not being within the preset pyrolysis gas temperature range, the pyrolysis gas intake volume of the corresponding high-temperature pyrolysis chamber 2 is adjusted or / and the heating power of the corresponding high-temperature pyrolysis chamber 2 is adjusted to meet the preset pyrolysis gas temperature range, and the method further includes: In response to the fact that the temperature of the pyrolysis gas after heating in any high-temperature pyrolysis chamber 2 is higher than the upper limit of the preset pyrolysis gas temperature range and the flue gas temperature is not higher than the preset flue gas temperature limit, the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 is increased or / and the opening of the corresponding high-temperature pyrolysis chamber 2 pyrolysis gas regulating valve 53 is increased to increase the pyrolysis gas intake of the corresponding high-temperature pyrolysis chamber 2. In response to the pyrolysis gas temperature after heating in any high-temperature pyrolysis chamber 2 being higher than the upper limit of the preset pyrolysis gas temperature range, the flue gas temperature not being higher than the preset flue gas temperature limit, and the opening degree of the corresponding high-temperature pyrolysis chamber 2's pyrolysis gas regulating valve 53 reaching the maximum opening degree, the heating power regulator 55 of the corresponding high-temperature pyrolysis chamber 2 is controlled to reduce the heating power.

[0053] In this embodiment, monitoring the combustion of the pyrolysis gas discharged from the high-temperature pyrolysis chamber 2 includes: The controller 56 receives flame information outside the outlet of the high-temperature pyrolysis chamber 2 collected by the flame monitoring element 51, and / or receives CO concentration information of the flue gas after the combustion of pyrolysis gas collected by the CO sensor 58. The controller 56 determines whether the flame is normal based on the flame information, or / and the controller determines whether the CO concentration exceeds a predetermined threshold based on the CO concentration information; wherein, the flame information includes whether the flame is continuous, whether the flame is extinguished, and / or the flame temperature; if the flame is discontinuous, the flame is extinguished, and / or the flame temperature is lower than the preset threshold, the flame is determined to be abnormal, otherwise the flame is determined to be normal. If the flame is abnormal or / and the CO concentration exceeds a predetermined threshold, the combustion condition is determined to be unsatisfactory; otherwise, the combustion condition is determined to be satisfactory.

[0054] Example 4: In this embodiment, a load regulation system for the high-temperature pyrolysis chamber 2 of a thermomagnetic vaporization device is used to implement the load regulation method for the high-temperature pyrolysis chamber of the thermomagnetic vaporization device in Embodiment 3 above. The system includes: Three high-temperature pyrolysis chambers 2, such as Figure 7 As shown, the air inlets of the three high-temperature pyrolysis chambers 2 are all connected to the magnetized pyrolysis gasification chamber 1 of the thermomagnetic gasification device through the pyrolysis gas passage 3. The magnetized pyrolysis gasification chamber 1 generates pyrolysis gas and transmits it to the three high-temperature pyrolysis chambers 2 through the pyrolysis gas passage 3. The three high-temperature pyrolysis chambers 2 are chambers used to heat the pyrolysis gas. After heating, the pyrolysis gas is discharged from the high-temperature pyrolysis chamber 2 and then burned. The flue gas generated after combustion is discharged to the exhaust gas treatment system 4. The magnetized pyrolysis gasification chamber 1 includes a gasification chamber body 11, a feeding mechanism 12 placed outside the gasification chamber body 11, an ash removal mechanism 13 placed below the gasification chamber body 11, a gasification chamber pyrolysis gas outlet 14 placed on the gasification chamber body 11 for connection with the pyrolysis gas passage 3, an air magnetization device 15 placed outside the gasification chamber body 11, and an air distribution pipe 16 placed inside the gasification chamber body 11. The gasification chamber body 11 can pyrolyze organic waste or medical waste entering the gasification chamber body 11 to generate pyrolysis gas, and discharge the pyrolysis gas into the pyrolysis gas passage 3. Then, the pyrolysis gas enters the high-temperature pyrolysis chamber 2 through the pyrolysis gas passage 3 for further secondary pyrolysis and combustion. The gas after secondary pyrolysis and combustion is then discharged to the exhaust gas treatment system 4. This embodiment uses three parallel high-temperature pyrolysis chambers 2 for illustration. In actual applications, the number of high-temperature pyrolysis chambers 2 can also be other, such as two, four, five, six, etc. A combustion flame monitoring device is used to monitor the combustion status of the high-temperature pyrolysis chamber 2. The combustion flame monitoring device includes a flame monitoring element and / or a CO sensor 58. The flame monitoring element 51 is an ion probe, photoelectric eye, and / or temperature detection element installed outside the pyrolysis gas outlet of each high-temperature pyrolysis chamber 2. The flame monitoring element 51 can collect flame information outside the outlet of each high-temperature pyrolysis chamber 2 and can detect whether the combustion status of some or all high-temperature pyrolysis chambers meets the expected state. The CO sensor 58 can be installed inside the exhaust gas treatment system 4 or between the exhaust gas treatment system 4 and each exhaust gas treatment system 2. If the CO sensor 58 is installed inside the exhaust gas treatment system 4 in the flue gas passage between the high-temperature pyrolysis chambers 2, it detects the CO concentration information after the flue gas from each high-temperature pyrolysis chamber 2 has merged after combustion. This can detect whether the combustion status of all high-temperature pyrolysis chambers meets the expected state. If the CO sensor 58 is installed in the flue gas passage between the exhaust gas treatment system 4 and each high-temperature pyrolysis chamber 2, it detects the CO concentration information before the flue gas from each high-temperature pyrolysis chamber 2 has merged after combustion. This can detect whether the combustion status of some or all high-temperature pyrolysis chambers meets the expected state. The first temperature sensor 52 is used to monitor the temperature of the pyrolysis gas after heating in each high-temperature pyrolysis chamber 2. The first temperature sensor is located on the side of each high-temperature pyrolysis chamber near the outlet. The second temperature sensor 57 is used to collect the flue gas temperature in the exhaust gas treatment system 4. The second temperature sensor is set at the inlet of the exhaust gas treatment system 4 or on the flue gas passage in the exhaust gas treatment system 4. The pyrolysis gas regulating valve 53, which is installed at the air inlet of each high-temperature pyrolysis chamber 2, is used to regulate the pyrolysis gas intake of each high-temperature pyrolysis chamber 2. The heating power regulator 55 installed on each high-temperature pyrolysis chamber 2 is used to adjust the heating power of each high-temperature pyrolysis chamber 2. The afterburning system 54 is used to replenish fuel to the high-temperature pyrolysis chamber 2; The controller 56 is used to: monitor the temperature of the pyrolysis gas after heating in each high-temperature pyrolysis chamber 2; monitor the combustion status of each high-temperature pyrolysis chamber 2; in response to the temperature of the pyrolysis gas after heating in any high-temperature pyrolysis chamber 2 not being within the preset pyrolysis gas temperature range, adjust the pyrolysis gas intake of the corresponding high-temperature pyrolysis chamber 2 and / or adjust the heating power of the corresponding high-temperature pyrolysis chamber 2 to meet the preset pyrolysis gas temperature range; in response to the combustion status of some or all of the high-temperature pyrolysis chamber 2 not meeting the expected state, add fuel to the high-temperature pyrolysis chamber 2 and / or increase the pyrolysis gas intake of some or all of the high-temperature pyrolysis chamber 2 to make the combustion status meet the expected state; in response to the flue gas temperature being higher than the preset flue gas temperature limit, reduce the pyrolysis gas production of the magnetized pyrolysis gasification chamber 1 and / or reduce the opening of the pyrolysis gas regulating valve 53 of each high-temperature pyrolysis chamber 2 to reduce the pyrolysis gas intake of the high-temperature pyrolysis chamber 2. Increasing the pyrolysis gas intake of the high-temperature pyrolysis chamber 2 refers to closing the pyrolysis gas regulating valve 53 of part of the high-temperature pyrolysis chamber 2 and / or controlling the pyrolysis gas regulating valve 53 of the high-temperature pyrolysis chamber 2 whose combustion conditions do not meet the expected state to increase the opening degree. Increasing the pyrolysis gas intake of the entire high-temperature pyrolysis chamber 2 refers to controlling the pyrolysis gas regulating valve 53 of the entire high-temperature pyrolysis chamber 2 to increase the opening degree.

[0055] In this embodiment, the afterburning system 54 includes a fuel nozzle, a fuel pipeline, and a control valve. The fuel nozzle is used to inject fuel oil or fuel gas into the pyrolysis gas. The fuel nozzle is located at the air inlet of each high-temperature pyrolysis chamber 2 or in the pyrolysis gas passage 3 between the high-temperature pyrolysis chamber 2 and the magnetized pyrolysis gasification chamber 1. The fuel pipeline is connected to the fuel nozzle and is used to supply fuel oil or fuel gas to the fuel nozzle. The control valve is used to control the on / off state of the fuel pipeline.

[0056] In this embodiment, the afterburning system 54 also includes an openable and closable protective cover disposed outside the fuel nozzle. The openable and closable protective cover has a protective posture and a working posture.
