Description

Automatic air distribution system and method for magnetic pyrolysis gasification chamber and thermal magnetic gasification device Technical Field

[0001] The present invention relates to the technical field of solid waste treatment, and in particular to an automatic air distribution system and method for a magnetized pyrolysis gasification chamber, and a thermomagnetic gasification device. Background Art

[0002] A thermomagnetic gasification device uses oxygen-carrying magnetized gas (also known as a thermomagnetic field environment) to pyrolyze and gasify organic and medical waste. The pyrolyzed gas is then fed into an exhaust gas treatment system for further treatment, achieving standard exhaust emissions. Devices using similar principles are also known as magnetic pyrolysis devices, magnetic cracking devices, or magnetic incineration devices. The thermomagnetic gasification device referred to in this invention also includes magnetic pyrolysis devices, magnetic cracking devices, or magnetic incineration devices using similar principles.

[0003] Thermal magnetic gasification devices are commonly used to treat medical waste and other organic solid waste. Numerous patents and technical literature domestically and internationally describe thermal magnetic gasification technology and devices. However, because the entire process must be conducted in a semi-enclosed, oxygen-deficient environment, the internal space is filled with pyrolysis gas, which is complex, flammable, and explosive. Successful continuous operation of this device is rare, both domestically and internationally. One of the key challenges lies in the design and precise control of the air distribution system that ensures balanced distribution of oxygen-laden magnetized gas to all areas within the material zone within the magnetized pyrolysis gasification chamber.

[0004] Thermal magnetic gasification devices typically include a magnetized pyrolysis gasification chamber and a pyrolysis gas post-processing device. The chamber uses oxygen-laden magnetized gas (typically obtained by magnetizing air) to generate pyrolysis gas from organic or medical waste. Due to the lack of mature structural design and control methods for the air distribution system, existing systems are typically simple, typically using manual dampers to adjust the air volume. Operators manually adjust the air volume based on experience or parameters measured by appropriate measuring instruments. Furthermore, because the air distribution duct outlets are not arranged in a three-dimensional pattern within the chamber, the oxygen-laden magnetized gas is difficult to penetrate, particularly in the central region of the chamber during normal operation. This results in material accumulation in the central region, impacting the balanced and continuous operation of the pyrolysis gasification process. In addition, there is no design to ventilate the horizontal layered areas from bottom to top separately and control the air supply volume independently. As a result, it is impossible to accurately supply air according to the pyrolysis and gasification reaction temperature and speed of each horizontal layered area, making the pyrolysis and gasification process unable to be effectively controlled. In addition, the amount and composition of medical waste input fluctuates at any time. Therefore, most of the time when the equipment is running, the amount of oxygen-containing magnetized gas entering different areas of the pyrolysis and gasification chamber is not effectively regulated. As a result, different areas of the magnetized pyrolysis and gasification chamber are either insufficiently supplied with air volume, resulting in slow pyrolysis and gasification speeds and incomplete reactions, making it difficult for the entire thermal magnetic gasification device to operate effectively and continuously; or the air volume is too large, causing the pyrolysis and gasification reaction to become a combustion reaction, which not only causes the amount and composition of the pyrolysis gas produced to fluctuate violently, but can even cause serious deflagration. This not only makes it difficult to continuously meet exhaust emission standards, but also causes the entire pyrolysis chamber to operate in an unbalanced, unstable, and unsafe state. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic air distribution system, method and thermal magnetic gasification device for a magnetized pyrolysis gasification chamber, which can accurately and effectively adjust the air distribution volume, accurately control the pyrolysis temperature, speed and oxygen content of the pyrolysis gas, thereby ensuring the continuous, stable and safe operation of the equipment.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] In the first aspect, the present invention provides an automatic air distribution system for a magnetized pyrolysis gasification chamber, comprising a magnetizing box, an air distribution pipe, a parameter acquisition element, and a controller, wherein the number of the magnetizing box is at least one, the air inlet a of each magnetizing box is connected to the air source, the air outlet b of the magnetizing box is connected to the air inlet c of multiple air distribution pipes, the air outlets d of the multiple air distribution pipes extend into the magnetized pyrolysis gasification chamber, and the magnetized gas with oxygen is delivered to different areas of the material area inside the magnetized pyrolysis gasification chamber through the air outlets d of the multiple air distribution pipes; the parameter acquisition element is used to collect the magnetized gas. The operating parameters of different areas of the material area inside the pyrolysis gasification chamber; the air inlet a of the magnetization box is arranged with a regulating valve corresponding to different areas, and the gas inlet amount of different areas of the internal material area is regulated by adjusting the opening of the regulating valve; the parameter acquisition element and the regulating valve are connected to a controller, and the controller obtains the operating parameters of different areas of the material area inside the magnetization pyrolysis gasification chamber collected by the parameter acquisition element, calculates the target opening of the regulating valve corresponding to the different areas, controls the regulating valve to operate to the target opening, and realizes automatic adjustment of the air inlet amount of each area.

[0008] Furthermore, the different areas of the material zone inside the magnetized pyrolysis gasification chamber include two or more layered areas stacked from top to bottom; the air distribution pipe includes two or more air distribution pipe groups composed of multiple air distribution pipes arranged corresponding to the layered areas of the material zone inside the magnetized pyrolysis gasification chamber, and the magnetized gas with oxygen is delivered to the corresponding layered areas through the air outlets of the air distribution pipe groups; the magnetization box includes at least one cabin for allowing the oxygen-containing gas to pass through, and the air inlet of each cabin is provided with a regulating valve, and the air outlet of one cabin is connected to the air inlet of one air distribution pipe group. By adjusting the opening of the regulating valve, the amount of magnetized gas with oxygen entering the corresponding layered area is regulated.

[0009] Furthermore, the air distribution pipe group corresponding to each layered area includes at least one lateral air distribution pipe arranged on the side wall of the magnetized pyrolysis gasification chamber and / or at least one internal air distribution pipe arranged in the magnetized pyrolysis gasification chamber and with the air outlet inside the corresponding layered area. The magnetized gas with oxygen is transported from the side to the corresponding layered area through the air outlet of the lateral air distribution pipe, and the magnetized gas with oxygen is transported to the material around the air outlet of the internal air distribution pipe in the corresponding layered area through the air outlet of the internal air distribution pipe.

[0010] Furthermore, the parameter acquisition element includes a temperature acquisition element for collecting temperatures in different areas of the magnetized pyrolysis gasification chamber; the controller obtains the temperatures of different areas of the magnetized pyrolysis gasification chamber collected by the temperature acquisition element, calculates the target opening of the regulating valve corresponding to the different areas, controls the regulating valve to operate to the target opening, and realizes automatic adjustment of the oxygen-containing magnetized gas inlet volume of each area.

[0011] Furthermore, the parameter acquisition element also includes an oxygen content sensor disposed above the material area or within the pyrolysis gas exhaust channel, which collects the oxygen content of the pyrolysis gas via the oxygen content sensor. The controller obtains the oxygen content of the pyrolysis gas collected by the oxygen content sensor and, in response to the oxygen content collected by the oxygen content sensor exceeding a preset threshold, performs a feeding operation to add new material and / or controls the regulating valve to reduce its opening. In response to the oxygen content collected by the oxygen content sensor not exceeding the preset threshold, the regulating valve opening is maintained unchanged. In the event of a conflict between the temperature data and the oxygen content data simultaneously obtained by the controller, the regulating valve opening is preferentially set based on the oxygen content data.

[0012] Furthermore, the magnetized pyrolysis gasification chamber is a device that performs magnetized pyrolysis gasification on materials by introducing magnetized gas containing oxygen to generate pyrolysis gas.

[0013] Furthermore, the magnetized pyrolysis gasification chamber includes a chamber for carrying materials and performing magnetized pyrolysis gasification reaction, an air inlet for introducing magnetized gas containing oxygen, and an air outlet for discharging pyrolysis gas.

[0014] In a second aspect, the present invention provides an automatic air distribution method for a magnetized pyrolysis gasification chamber, which uses the above-mentioned automatic air distribution system for the magnetized pyrolysis gasification chamber to perform automatic air distribution.

[0015] In a third aspect, the present invention provides a thermal magnetic gasification device, which includes a magnetic pyrolysis gasification chamber and a pyrolysis gas post-processing device, and is characterized in that the magnetic pyrolysis gasification chamber is equipped with the above-mentioned automatic air distribution system for the magnetic pyrolysis gasification chamber.

[0016] Beneficial effects of the present invention:

[0017] 1. The present invention collects the operating parameters of the magnetized pyrolysis gasification chamber in real time through a parameter acquisition element disposed within the chamber, and transmits the acquired operating parameters to a controller. The controller then calculates the target opening of the air inlet regulating valve of the magnetized chamber based on the operating parameters of the magnetized pyrolysis gasification chamber acquired by the parameter acquisition element, controls the regulating valve to operate to the target opening, and thereby automatically adjusts the air flow into the air distribution duct, ensuring that the air flow is compatible with the operating conditions of the thermal magnetic gasification device, and avoiding the impact of excessive or insufficient air flow and uneven air flow distribution between different areas of the material zone within the magnetized pyrolysis gasification chamber on the safe and stable operation of the device, i.e., the thermal magnetic gasification device.

[0018] 2. The different regions of the material area within the magnetized pyrolysis gasification chamber of the present invention include two or more layered regions stacked from top to bottom, and the air distribution pipe includes two or more air distribution pipe groups arranged corresponding to the layered regions of the material area within the magnetized pyrolysis gasification chamber, and the magnetized gas with oxygen is delivered to the corresponding layered regions of the magnetized pyrolysis gasification chamber through the air outlets of the air distribution pipe groups; the magnetized box includes at least one chamber for allowing oxygen-containing gas to pass through, and the air inlet of each chamber for allowing oxygen-containing gas to pass through is provided with a regulating valve, that is, the regulating valve on the independent chamber for allowing oxygen-containing gas to pass through is used to adjust the amount of gas entering the corresponding passage, so that the air supply to the corresponding layered region is uniform and appropriate, and the adjustment of the air supply amount will directly affect the speed of the pyrolysis reaction, and thus affect the temperature of the region and the temperature of the pyrolysis gas. This targeted adjustment will be able to meet the air supply needs of different areas of the material area inside the magnetized pyrolysis gasification chamber, avoiding the excessive introduction of magnetized gas with oxygen, which will cause the pyrolysis reaction to accelerate or even turn into combustion, and the occurrence of serious deflagration. It can also avoid the situation where the pyrolysis reaction is slowed down due to the introduction of too little magnetized gas with oxygen, and even affects the continuous and stable progress of the pyrolysis reaction.

[0019] 3. The air distribution pipe group corresponding to the layered area described in the present invention includes at least one lateral air distribution pipe arranged on the side wall of the magnetized pyrolysis gasification chamber and at least one internal air distribution pipe arranged in the magnetized pyrolysis gasification chamber. Through the coordinated use of the lateral air distribution pipe and the internal air distribution pipe, it is ensured that the magnetized gas with oxygen can effectively enter different areas of the material area, especially the central area where materials are easily accumulated. It can effectively ensure the uniform air supply in various areas of the material area, including the central area, and solve the problems of local uneven air supply and imbalance of pyrolysis rate and temperature in various areas.

DETAILED DESCRIPTION

[0025] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0026] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. The illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0027] In one embodiment, an automatic air distribution system for a thermal magnetic gasification device is provided, as shown in Figures 1 and 2, comprising a magnetization box 1, an air distribution pipe 2, a parameter acquisition element 3 and a controller 4. There is at least one magnetization box 1, and the air inlet a of each magnetization box is connected to an air source. The air outlet b of the magnetization box 1 is connected to the air inlet c of multiple air distribution pipes 2, and the air outlet d of the multiple air distribution pipes 2 extends into the magnetization pyrolysis gasification chamber 5. The magnetized gas with oxygen is delivered to different areas of the material area inside the magnetization pyrolysis gasification chamber 5 through the air outlet d of the multiple air distribution pipes 2, so that the material in the magnetization pyrolysis gasification chamber 5 can reach the predetermined air supply volume, ensuring that the material can be uniformly magnetized, pyrolyzed and gasified, thereby improving the material processing quality.

[0028] The parameter acquisition element 3 is used to collect operating parameters of different areas within the material zone of the magnetized pyrolysis gasification chamber 5. The air inlet a of the magnetized box 1 is provided with a regulating valve 6 corresponding to different areas within the material zone of the pyrolysis gasification chamber 5. By adjusting the opening of the regulating valve 6, the amount of magnetized gas with oxygen entering different areas of the material zone can be adjusted.

[0029] The parameter acquisition element 3 and the regulating valve 6 are both connected to the controller 4 for data transmission, with the parameter acquisition element 3 serving as an information input device and the regulating valve 6 serving as an actuator. The controller 4 obtains the operating parameters of different regions of the material area within the magnetized pyrolysis gasification chamber 5 collected by the parameter acquisition element 3, calculates the target openings of the regulating valve 6 corresponding to the different regions, and controls the regulating valve 6 to operate to the target openings, thereby automatically adjusting the air intake volume of each region to ensure that the air supply volume of the air distribution pipe 2 is compatible with the operating conditions of the magnetized pyrolysis gasification chamber 5, thereby preventing the equipment, i.e., the magnetized pyrolysis gasification chamber 5, from having difficulty in stable operation due to excessive or insufficient air supply volume.

[0030] It should be noted that the regulating valve 6 described in the present application is arranged at the air inlet a position of the magnetizing box 1, and the air inlet volume of the air distribution duct 2 is regulated by adjusting the air inlet volume of the magnetizing box 1.

[0031] In this embodiment, the gas source is ordinary air. A magnetic material 13 in contact with the gas is arranged in the magnetization box 1. The ordinary air entering the air distribution pipe through the magnetization box is magnetized by the magnetic material 13 to become magnetized air. The magnetized air is then sent into different areas of the material accumulation in the magnetization pyrolysis gasification chamber 5 through the air distribution pipe 2, ensuring full contact between the material and the magnetized air, thereby avoiding insufficient contact between the material and the magnetized air in local areas, especially in the middle area, which affects the magnetization pyrolysis gasification effect.

[0032] In this embodiment, the magnetized pyrolysis and gasification chamber 5 performs magnetized pyrolysis and gasification on the material by introducing magnetized gas containing oxygen to generate pyrolysis gas. For example, the magnetized pyrolysis and gasification chamber 5 includes a chamber for carrying the material and performing the magnetized pyrolysis and gasification reaction, an air inlet for introducing the magnetized gas containing oxygen, and an outlet for exhausting the pyrolysis gas.

[0033] In one embodiment, as shown in FIG1 , the different regions of the material area inside the magnetized pyrolysis gasification chamber 5 include two or more layered regions stacked from top to bottom. The air distribution pipe 2 includes two or more air distribution pipe groups composed of multiple air distribution pipes arranged corresponding to the layered regions of the material area inside the magnetized pyrolysis gasification chamber 5, and the magnetized air is delivered to the corresponding layered region of the magnetized pyrolysis gasification chamber 5 through the air outlet d of a single air distribution pipe group. The magnetization box 1 includes at least one cabin for air to pass through, and the air inlet of each cabin is provided with a regulating valve 6. The air outlet of one cabin is connected to the air inlet c of one air distribution pipe group. By adjusting the opening of the regulating valve 6, the amount of magnetized air entering the corresponding layered region is regulated.

[0034] The different areas of the material area inside the magnetized pyrolysis gasification chamber 5 are divided into zones by a stacked partitioning method, which is mainly based on the magnetized pyrolysis gasification reaction mechanism. The requirements of the operating conditions for a single layered area are basically the same. The stacked partitioning method can effectively control the operating parameters of the corresponding area, and facilitates the arrangement of the air distribution duct 2 and the precise control of the air distribution volume.

[0035] For example, referring to Figures 1 and 3, the different regions of the material area within the magnetized pyrolysis gasification chamber 5 include two layered regions stacked from top to bottom, namely, an upper layered region 7 and a lower layered region 8. The air distribution pipe 2 includes a first air distribution pipe group 21 and a second air distribution pipe group 22, which are arranged corresponding to the upper and lower layered regions of the material area within the magnetized pyrolysis gasification chamber 5. The magnetized air, i.e., the magnetized gas with oxygen, is delivered to the upper layered region 7 of the magnetized pyrolysis gasification chamber 5 through the air outlet of the first air distribution pipe group 21, and the magnetized air, i.e., the magnetized gas with oxygen, is delivered to the lower layered region 8 of the magnetized pyrolysis gasification chamber 5 through the air outlet of the second air distribution pipe group 22.

[0036] As shown in Figure 3, there is one magnetizing box 1, each of which includes two independent air-permeable compartments, namely a first compartment 11 and a second compartment 12. The air inlets of the first compartment 11 and the second compartment 12 are connected to an air source, and a regulating valve 6 is arranged at the air inlet of each air-permeable compartment. The air outlet of the first compartment 11 is connected to the air inlet of the first air distribution duct group 21, and the air outlet of the second compartment 12 is connected to the air inlet of the second air distribution duct group 22. By adjusting the opening of the regulating valve 6, the amount of magnetized air entering the corresponding layered area can be adjusted.

[0037] Alternatively, there are at least two magnetizing boxes 1, each of which is provided with a cabin for air to pass through. The cabins of one part of the magnetizing box 1 are connected to the air inlet of the first air distribution pipe group 21, and the magnetized air is transported to the upper layered area of ​​the magnetizing pyrolysis gasification chamber 5 through the air outlet of the first air distribution pipe group 21; the cabins of the other part of the magnetizing box 1 are connected to the air inlet of the second air distribution pipe group 22, and the magnetized air is transported to the lower layered area of ​​the magnetizing pyrolysis gasification chamber 5 through the air outlet of the second air distribution pipe group 22.

[0038] According to actual application requirements, the number of compartments through which air passes in the magnetization box 1 is reasonably arranged, and the compartments are connected to the corresponding air distribution pipe groups to ensure the air supply requirements of different areas of the material area inside the magnetization pyrolysis gasification chamber 5.

[0039] In one embodiment, referring to Figures 1 and 3, the air distribution pipe group corresponding to each layered area includes at least one lateral air distribution pipe 23 arranged on the side wall of the magnetized pyrolysis gasification chamber 5 and / or at least one internal air distribution pipe 24 arranged in the magnetized pyrolysis gasification chamber 5 and with the air outlet inside the corresponding layered area. The magnetized air is transported from the side to the corresponding layered area through the air outlet of the lateral air distribution pipe 23, and the magnetized air is transported to the material around the air outlet of the internal air distribution pipe 24 in the corresponding layered area through the air outlet of the internal air distribution pipe 24.

[0040] Taking the upper and lower layered regions as an example, the first air distribution pipe group 21 corresponding to the upper layered region 7 includes at least one first lateral air distribution pipe 231 arranged on the side wall of the magnetized pyrolysis gasification chamber 5 and at least one first internal air distribution pipe 241 arranged in the magnetized pyrolysis gasification chamber 5. The air inlet of the first lateral air distribution pipe 231 is connected to the air outlet of the first compartment 11 of the magnetization box 1, and the air outlet of the first lateral air distribution pipe 231 extends into the magnetized pyrolysis gasification chamber 5 and faces the upper layered region 7 of the internal material area. The magnetized air is transported to the upper layered region 7 of the material area corresponding to the surrounding area of ​​the air outlet through the air outlet of the first lateral air distribution pipe 231, that is, the magnetized air is transported from the side to the upper layered region 7 through the air outlet of the first lateral air distribution pipe 231.

[0041] The air inlet of the first internal air distribution pipe 241 is connected to the air outlet of the first compartment 11 of the magnetization box 1. The air outlet of the first internal air distribution pipe 241 extends into the magnetized pyrolysis gasification chamber 5 and faces the upper layered area 7 of the internal material area. The magnetized air is transported to the upper layered area 7 of the material area corresponding to the surrounding area of ​​the air outlet through the air outlet of the first internal air distribution pipe 241, that is, the magnetized air is transported to the material around the air outlet in the corresponding layered area through the air outlet of the first internal air distribution pipe 241.

[0042] The first lateral air distribution duct 231 meets the air supply needs of the outer layered area 7 above the material area, while the first internal air distribution duct 241 extends into the upper layered area 7 of the material area, ensuring sufficient contact between the material and the magnetized air. This prevents localized areas, particularly those in the middle of the upper layered area 7, from insufficient contact with the magnetized air, which could affect the balance and stability of the magnetic pyrolysis and gasification process. The synergistic effect of the first lateral air distribution duct 231 and the first internal air distribution duct 241 effectively ensures the smooth progress of the thermal magnetic gasification reaction throughout the upper layered area 7, improving the balance and efficiency of the pyrolysis of materials in each area.

[0043] Similarly, the second air distribution pipe group 22 corresponding to the lower layered area 8 includes at least one second lateral air distribution pipe 232 arranged on the side wall of the magnetized pyrolysis gasification chamber 5 and at least one second internal air distribution pipe 242 arranged inside the magnetized pyrolysis gasification chamber 5.

[0044] The air inlet of the second lateral air distribution pipe 232 is connected to the air outlet of the second compartment 12 of the magnetization box 1, and the air outlet of the second lateral air distribution pipe 232 extends into the magnetized pyrolysis gasification chamber 5 and faces the lower layered area 8 of the internal material area. The magnetized air is transported to the lower layered area 8 of the material area corresponding to the surrounding area of ​​the air outlet through the air outlet of the second lateral air distribution pipe 232, that is, the magnetized air is transported from the side to the lower layered area 8 through the air outlet of the second lateral air distribution pipe 232.

[0045] The air inlet of the second internal air distribution pipe 242 is connected to the air outlet of the second compartment 12 of the magnetization box 1, and the air outlet of the second internal air distribution pipe 242 extends into the magnetized pyrolysis gasification chamber 5 and faces the lower layered area 8 of the internal material area. The magnetized air is transported to the lower layered area 8 of the material area corresponding to the surrounding area of ​​the air outlet through the air outlet of the second internal air distribution pipe 242, that is, the magnetized air is transported to the material around the air outlet in the corresponding layered area through the air outlet of the second internal air distribution pipe 242.

[0046] Illustratively, the second internal air distribution pipe 242 includes at least one vertical internal air distribution pipe 2421 vertically arranged in the magnetized pyrolysis gasification chamber 5 and at least one horizontal air distribution pipe 2422 horizontally arranged at the lower part of the magnetized pyrolysis gasification chamber 5 .

[0047] In one embodiment, as shown in FIG1 , the parameter acquisition element 3 includes a temperature acquisition element 31 for acquiring temperatures in different regions of the magnetized pyrolysis vaporization chamber. The controller 4 obtains the temperatures of different regions of the magnetized pyrolysis vaporization chamber 5 as acquired by the temperature acquisition element 31, calculates the target openings of the regulating valve 6 corresponding to each region, and controls the regulating valve 6 to operate to the target openings, thereby automatically adjusting the airflow to each region.

[0048] Specifically, the controller 4 adjusts the opening of the regulating valve 6 of the corresponding magnetizing box 1 according to the real-time temperature collected by the temperature collection element 31. When the temperature is high, the opening of the regulating valve is reduced, and when the temperature is low, the opening of the regulating valve is increased, thereby adjusting the pyrolysis reaction speed and temperature of different areas of the corresponding material area by adjusting the air intake of the magnetized air.

[0049] Exemplarily, the regulating valve 6 has different opening levels, such as 0% (fully closed), 20%, 50%, 80%, and 100% (fully open). Taking the upper and lower layered regions as an example, the number of compartments within the magnetizing box 1 through which the oxygen-carrying gas passes is two, namely, the first compartment 11 and the second compartment 12. The different opening levels of the regulating valve 6 can change the airflow into the first compartment 11 and the second compartment 12. It is worth noting that the aforementioned opening levels of the regulating valve 6 are provided for illustrative purposes only and are not intended to be limiting, and other technical solutions may also be employed. This embodiment is further illustrated below by way of example: temperature data from the temperature acquisition element 31 is acquired at regular intervals or in real time. When the acquired temperature exceeds a preset threshold, the regulating valve 6 is controlled to decrease its opening (e.g., from 80% to 50%) to reduce the airflow into the first compartment 11 or the second compartment 12. If the next acquired temperature data after the reduced opening of the regulating valve 6 is still above the preset threshold, the opening of the regulating valve 6 is further decreased until it is fully closed. When the collected temperature is lower than the preset threshold, the regulating valve 6 is controlled to increase its opening (such as from 50% opening to 80% opening) to increase the air intake of the first compartment 11 or the second compartment 12. If the next temperature data obtained after increasing the opening of the regulating valve 6 is still lower than the preset threshold, the opening of the regulating valve 6 will continue to be increased until it is fully opened.

[0050] In one embodiment, as shown in FIG1 , the parameter acquisition element 3 further includes an oxygen content sensor 32 disposed above the material area or within the pyrolysis gas exhaust passage, and the oxygen content of the pyrolysis gas is collected by the oxygen content sensor 32. For example, the oxygen content sensor 32 is disposed above the material area.

[0051] In response to the oxygen content above the material area collected by the oxygen content sensor 32 exceeding the preset threshold, a feeding operation of adding new material is performed or / and the regulating valve 6 is controlled to reduce its opening.

[0052] The controller 4 obtains the temperature data collected by the temperature collection element 31 and the oxygen content data of the pyrolysis gas collected by the oxygen content sensor 32, analyzes the temperature and speed of the pyrolysis and gasification reaction in different areas of the magnetized pyrolysis and gasification chamber 5, calculates the target opening of the regulating valve 6 corresponding to the different areas, controls the regulating valve 6 to operate to the target opening, and realizes automatic adjustment of the inlet volume of the magnetized gas with oxygen in each area, thereby realizing the adjustment of the pyrolysis and gasification temperature and speed of each area, as well as the residual oxygen content in the generated pyrolysis gas.

[0053] When the temperature data and oxygen content data simultaneously acquired by the controller 4 conflict, the oxygen content data is prioritized in setting the target opening of the control valve 6. For example, when the acquired temperature is below a preset threshold and the oxygen content of the pyrolysis gas exceeds a preset value, the control valve 6 is controlled to open wider when the acquired temperature is below the threshold; when the oxygen content of the pyrolysis gas exceeds the preset value, the control valve 6 is controlled to open narrower, which conflicts with the increased opening obtained based on the temperature data. In this case, the control logic prioritizes the oxygen content data, resulting in the output action being to control the control valve 6 to open narrower.

[0054] In one embodiment, the number of the magnetizing boxes 1 is two or more, and they are evenly spaced along the circumference of the magnetizing pyrolysis gasification chamber 5. As shown in FIG2 , for example, the number of the magnetizing boxes 1 is four, and they are evenly spaced along the circumference of the magnetizing pyrolysis gasification chamber 5.

[0055] For example, when the number of layered regions stacked from top to bottom is small, for example, two or three, each magnetizing box 1 is provided with air-permeable compartments corresponding to the number of layered regions, with one air-permeable compartment corresponding to one layered region, and the two compartments are connected by at least one air distribution duct assembly. When the number of layered regions stacked from top to bottom is large, for example, three or more, each magnetizing box is provided with one or two magnetized air-permeable compartments, and when multiple magnetizing boxes 1 are used in combination, the magnetized air-permeable compartments are connected to the corresponding layered regions via at least one air distribution duct assembly.

[0056] Furthermore, given the unstable source of medical waste and the need for maintenance, the equipment must be capable of multiple operating modes, including normal operation, low-load operation, and shutdown, with manual and automatic switching between these modes. Therefore, the automatic air distribution system for the thermomagnetic vaporization unit can also automatically execute different control logics based on different operating conditions.

[0057] When the device is operating normally, the temperature acquisition element 31 and the oxygen content sensor 32 detect the operating parameters in real time and send the operating parameters to the controller 4. The controller 4 sends instructions to adjust the opening of the regulating valve 6 at the air inlet a position of the magnetizing box 1 in real time according to the pre-set control logic.

[0058] When the equipment is running at low load, the controller 4 sends instructions to adjust the opening of the regulating valve 6 at the air inlet a position of the magnetizing box 1 in real time according to the preset control logic, to ensure that the equipment will not affect stable operation or cause serious explosion accidents due to excessive or insufficient air intake.

[0059] When the equipment is shut down normally, the controller 4 sends instructions to adjust the opening of the regulating valve 6 at the air inlet a position of the magnetizing box 1 in real time according to the set control logic. After ensuring that all medical waste in the equipment has been processed, the air supply is automatically stopped. The whole process does not require human intervention.

[0060] In one embodiment, an automatic air distribution method for a thermal magnetic vaporization device is provided. The method utilizes the automatic air distribution system for a magnetic pyrolysis vaporization chamber described in any of the above embodiments to automatically distribute air. The method includes: using a parameter acquisition component 3 to collect operating parameters of the magnetic pyrolysis vaporization chamber 5 in real time, and transmitting the collected operating parameters to a controller 4. The controller 4 obtains the operating parameters of the magnetic pyrolysis vaporization chamber 5 collected by the parameter acquisition component 3, calculates a target opening of a regulating valve 6, and controls the regulating valve 6 to operate to the target opening, thereby automatically adjusting the air flow into the air distribution duct 2.

[0061] In one embodiment, a thermal magnetic gasification device is provided, which includes a magnetic pyrolysis gasification chamber and a pyrolysis gas post-processing device. The magnetic pyrolysis gasification chamber is equipped with the automatic air distribution system for the magnetic pyrolysis gasification chamber described in any of the above embodiments.

Any equivalent substitution or modification made by those skilled in the art based on the present invention is within the protection scope of the present invention.
