Abstract
Description
Technical Field
[0001] This invention relates to the field of solid waste treatment technology, specifically to an automatic air distribution system, method, and thermomagnetic gasification device for a magnetized pyrolysis gasification chamber. Background Technology
[0002] A thermomagnetic gasification device is a device that uses the introduction of magnetized gas containing oxygen (also known as a thermomagnetic field environment) to pyrolyze and gasify organic waste and medical waste, and then sends the pyrolysis gas into an exhaust gas treatment system for further exhaust gas treatment to achieve compliant emissions. Devices using similar principles are also called magnetized pyrolysis devices, magnetized pyrolysis devices, or magnetized incineration devices, etc. The thermomagnetic gasification device referred to in this invention also includes magnetized pyrolysis devices, magnetized pyrolysis devices, or magnetized incineration devices that use similar principles.
[0003] Thermomagnetic gasification devices are commonly used to treat medical waste and other organic solid waste. Numerous patents and technical documents both domestically and internationally have described the technology and devices involved in thermomagnetic gasification. However, because the entire process must be carried out in a semi-enclosed, oxygen-deficient environment, filled with complex and flammable / explosive pyrolysis gas, there are very few cases of continuous successful operation of this device, both domestically and internationally. One of the most critical challenges lies in the design and precise control of the air distribution system that ensures balanced distribution of oxygenated magnetized gas across all areas within the material zone of the magnetization pyrolysis gasification chamber.
[0004] Magnetorheological gasification devices typically include a magnetized pyrolysis gasification chamber and a pyrolysis gas post-processing unit. The magnetized pyrolysis gasification chamber uses oxygen-containing magnetized gas (usually obtained by magnetizing air) to magnetize and pyrolyze organic or medical waste to generate pyrolysis gas. Due to the lack of mature structural design and control methods for the air distribution system of magnetized pyrolysis gasification chambers, existing air distribution systems are usually quite simple, typically using manual air valves to adjust the airflow. Operators adjust these systems manually based on experience or parameters measured by appropriate instruments. Furthermore, because the air outlets of the distribution ducts are not arranged three-dimensionally within the magnetized pyrolysis gasification chamber, especially in the central area, oxygen-containing magnetized gas has difficulty penetrating during normal operation. This leads to material accumulation in the central area, affecting the balanced and continuous operation of the pyrolysis gasification process. Furthermore, the lack of separate ventilation and independent airflow control for each of the horizontally layered zones from bottom to top prevents precise airflow delivery based on the pyrolysis and gasification reaction temperature and speed of each zone, resulting in ineffective control over the pyrolysis and gasification process. In addition, the quantity and composition of the medical waste input fluctuate constantly, meaning that the amount of oxygen-laden magnetized gas entering different areas of the pyrolysis and gasification chamber is often poorly regulated during most of the equipment's operation. This leads to either insufficient airflow in different areas of the magnetized pyrolysis and gasification chamber, resulting in slow pyrolysis and gasification speeds and incomplete reactions, making it difficult for the entire thermomagnetic gasification device to operate effectively and continuously; or excessive airflow, causing the pyrolysis and gasification reaction to turn into a combustion reaction, leading to drastic fluctuations in the amount and composition of the generated pyrolysis gas and even potentially causing severe deflagration. This not only makes it difficult to consistently meet emission standards but also leaves the entire pyrolysis chamber operating in an unbalanced, unstable, and unsafe state. Summary of the Invention
[0005] The purpose of this invention is to provide an automatic air distribution system, method, and thermomagnetic vaporization device for a magnetized pyrolysis gasification chamber, which can accurately and effectively adjust the air distribution volume and precisely control the pyrolysis temperature, speed, and oxygen content of the pyrolysis gas, thereby ensuring the continuous, stable, and safe operation of the equipment.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0007] In a first aspect, the present invention provides an automatic air distribution system for a magnetized pyrolysis gasification chamber, comprising a magnetization box, air distribution ducts, a parameter acquisition element, and a controller. The number of magnetization boxes is at least one. The air inlet a of each magnetization box is connected to a gas source, and the air outlet b of each magnetization box is connected to the air inlets c of multiple air distribution ducts. The air outlets d of the multiple air distribution ducts extend into the magnetized pyrolysis gasification chamber, and oxygen-containing magnetized gas is delivered to different areas of the material zone inside the chamber through the air outlets d of the multiple air distribution ducts. The parameter acquisition element is used to collect magnetization data. The operating parameters of different areas of the material zone inside the pyrolysis gasification chamber are as follows: the air inlet a of the magnetization box is equipped with regulating valves corresponding to different areas. By adjusting the opening of the regulating valves, the gas intake of different areas of the internal material zone can be adjusted; the parameter acquisition element and the regulating valves are connected to the controller. The controller acquires the operating parameters of different areas of the material zone inside the magnetized pyrolysis gasification chamber collected by the parameter acquisition element, calculates the target opening of the regulating valves corresponding to different areas, and controls the regulating valves to operate to the target opening, thereby realizing the automatic adjustment of the air intake 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 pipes include 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 oxygen-containing magnetized gas is sent to the corresponding layered area through the air outlet of the air distribution pipe group; the magnetization box includes at least one chamber through which oxygen-containing gas passes, and each chamber's air inlet is equipped with a regulating valve, and the air outlet of one chamber is connected to the air inlet of one air distribution pipe group. By adjusting the opening of the regulating valve, the amount of oxygen-containing magnetized gas entering the corresponding layered area can be adjusted.
[0009] Furthermore, each layered region corresponds to an air distribution duct group including at least one lateral air distribution duct arranged on the side wall of the magnetized pyrolysis gasification chamber and / or at least one internal air distribution duct arranged inside the magnetized pyrolysis gasification chamber with its outlet inside the corresponding layered region. The lateral air distribution duct outlet is used to transport magnetized gas containing oxygen from the side into the corresponding layered region, and the internal air distribution duct outlet is used to transport magnetized gas containing oxygen to the material around the outlet of the internal air distribution duct in the corresponding layered region.
[0010] Furthermore, the parameter acquisition element includes a temperature acquisition element for acquiring the temperature of different areas of the magnetized pyrolysis gasification chamber; the controller acquires the temperature of different areas of the magnetized pyrolysis gasification chamber acquired by the temperature acquisition element, calculates the target opening degree of the regulating valve corresponding to different areas, controls the regulating valve to operate to the target opening degree, and realizes automatic adjustment of the air volume of the oxygen-containing magnetized gas in each area.
[0011] Furthermore, the parameter acquisition element also includes an oxygen content sensor arranged above the material zone or in the pyrolysis gas discharge channel, which acquires the oxygen content of the pyrolysis gas. The controller acquires the oxygen content of the pyrolysis gas acquired by the oxygen content sensor. In response to the oxygen content acquired by the oxygen content sensor exceeding a preset threshold, a feeding operation is performed to add new material and / or the opening of the regulating valve is reduced. In response to the oxygen content acquired by the oxygen content sensor not exceeding the preset threshold, the opening of the regulating valve remains unchanged. When the temperature data and oxygen content data acquired by the controller simultaneously contradict each other, the opening of the regulating valve is set preferentially based on the oxygen content data.
[0012] Furthermore, the magnetized pyrolysis gasification chamber is a device that magnetizes and pyrolyzes materials by introducing a magnetized gas containing oxygen to generate pyrolysis gas.
[0013] Furthermore, the magnetized pyrolysis gasification chamber includes a chamber for carrying materials and carrying out magnetized pyrolysis gasification reaction, an air inlet for introducing magnetized gas containing oxygen, and an air outlet for discharging pyrolysis gas.
[0014] Secondly, the present invention provides an automatic air distribution method for a magnetized pyrolysis gasification chamber. The automatic air distribution method employs the aforementioned automatic air distribution system for the magnetized pyrolysis gasification chamber. The automatic air distribution includes: real-time acquisition of operating parameters of different areas of the magnetized pyrolysis gasification chamber via a parameter acquisition element, and sending the acquired operating parameters to a controller; the controller acquires the operating parameters of the magnetized pyrolysis gasification chamber acquired by the parameter acquisition element, calculates the target opening degree of the regulating valve, and controls the regulating valve to operate to the target opening degree, thereby achieving automatic adjustment of the air intake volume of the air distribution pipe.
[0015] Thirdly, the present invention provides a thermomagnetic vaporization device, which includes a magnetized pyrolysis vaporization chamber and a pyrolysis gas post-processing device, characterized in that: the magnetized pyrolysis vaporization chamber is equipped with the above-mentioned automatic air distribution system for the magnetized pyrolysis vaporization chamber.
[0016] The beneficial effects of this invention are:
[0017] 1. This invention uses parameter acquisition elements arranged within the magnetized pyrolysis gasification chamber to collect the operating parameters of the chamber in real time and sends these parameters to the controller. The controller then calculates the target opening degree of the inlet regulating valve of the magnetization chamber based on the operating parameters collected by the parameter acquisition elements, and controls the regulating valve to operate at the target opening degree. This achieves automatic adjustment of the airflow in the distribution pipe, ensuring that the airflow is compatible with the operating conditions of the thermomagnetic gasification device. This avoids the safe and stable operation of the equipment (thermomagnetic gasification device) due to excessive or insufficient airflow or uneven airflow distribution in different areas of the material zone within the magnetized pyrolysis gasification chamber.
[0018] 2. The different regions of the material zone inside the magnetized pyrolysis gasification chamber of the present invention include two or more layered regions stacked from top to bottom, and the air distribution pipes include two or more air distribution pipe groups arranged corresponding to the layered regions of the material zone inside the magnetized pyrolysis gasification chamber. The magnetized gas carrying oxygen is sent to the corresponding layered region of the magnetized pyrolysis gasification chamber through the air outlet of the air distribution pipe group. The magnetization chamber includes at least one chamber through which oxygen-carrying gas passes. Each air inlet of the chamber through which oxygen-carrying gas passes is provided with a regulating valve. That is, the amount of gas entering the corresponding passage is regulated by the regulating valve on the independent chamber through which oxygen-carrying gas passes, so that the air supply to the corresponding layered region is uniform and appropriate. The regulation of the air supply will directly affect the rate of pyrolysis reaction, and thus affect the temperature of the region and the temperature of the pyrolysis gas. This targeted adjustment can meet the air supply needs of different areas of the material zone inside the magnetized pyrolysis gasification chamber, avoiding excessive introduction of oxygen-containing magnetized gas, which could accelerate the pyrolysis reaction or even turn it into combustion, or cause severe deflagration. It can also avoid insufficient introduction of oxygen-containing magnetized gas, which could slow down the pyrolysis reaction or even affect the continuous and stable progress of the pyrolysis reaction.
[0019] 3. The air distribution pipe group corresponding to the layered region described in this 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 inside 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 oxygen-containing magnetized gas can effectively enter different areas of the material zone, especially the central area where materials are prone to accumulate. This can effectively ensure uniform air supply to all areas of the material zone, including the central area, and solve the problems of uneven local air supply and imbalance of pyrolysis rate and temperature in different areas.

Detailed Implementation
[0025] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.
[0026] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0027] In one embodiment, an automatic air distribution system for a thermomagnetic vaporization apparatus is provided, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, the system includes a magnetization box 1, air distribution ducts 2, parameter acquisition elements 3, and a controller 4. There is at least one magnetization box 1. 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 inlets c of multiple air distribution ducts 2. The air outlets d of the multiple air distribution ducts 2 extend into the magnetization pyrolysis gasification chamber 5. The magnetized gas containing oxygen is delivered to different areas of the material zone inside the magnetization pyrolysis gasification chamber 5 through the air outlets d of the multiple air distribution ducts 2, so that the material in the magnetization pyrolysis gasification chamber 5 can reach the predetermined air supply, 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 the operating parameters of different areas of the material zone inside the magnetized pyrolysis gasification chamber 5. The air inlet a of the magnetization box 1 is equipped with regulating valves 6 corresponding to different areas of the material zone inside the pyrolysis gasification chamber 5. By adjusting the opening of the regulating valves 6, the amount of oxygen-containing magnetized gas entering different areas of the material zone can be regulated.
[0029] Both the parameter acquisition element 3 and the regulating valve 6 are connected to the controller 4 for data transmission. The parameter acquisition element 3 serves as the information input device, and the regulating valve 6 serves as the execution device. The controller 4 acquires the operating parameters of different areas inside the material zone of the magnetized pyrolysis gasification chamber 5 collected by the parameter acquisition element 3, calculates the target opening degree of the regulating valve 6 corresponding to different areas, and controls the regulating valve 6 to operate to the target opening degree, thereby realizing the automatic adjustment of the air intake of each area. This ensures that the air distribution volume of the air distribution pipe 2 is compatible with the operating conditions of the magnetized pyrolysis gasification chamber 5, and avoids the equipment, i.e., the magnetized pyrolysis gasification chamber 5, from being unable to operate stably due to excessive or insufficient air distribution.
[0030] It should be noted that the regulating valve 6 described in this application is located at the air inlet a of the magnetization box 1, and the air inlet volume of the air distribution pipe 2 is adjusted by adjusting the air inlet volume of the magnetization box 1.
[0031] In this embodiment, the gas source is ordinary air. The magnetization box 1 is equipped with a magnetizing material 13 that comes into contact with the gas. The ordinary air entering the air distribution pipe through the magnetization box is magnetized by the magnetizing material 13, becoming magnetized air. Then, the magnetized air is sent to different areas of the material piled up in the magnetization pyrolysis gasification chamber 5 through the air distribution pipe 2, ensuring that the material is in full contact with the magnetized air and avoiding insufficient contact between the material and the magnetized air in local areas, especially in the central area, which would affect the magnetization pyrolysis gasification effect.
[0032] In this embodiment, the magnetized pyrolysis gasification chamber 5 uses an oxygen-containing magnetized gas to magnetize and pyrolyze the material, generating pyrolysis gas. Exemplarily, the magnetized pyrolysis gasification chamber 5 includes a chamber for carrying the material and conducting the magnetized pyrolysis gasification reaction, an air inlet for introducing the oxygen-containing magnetized gas, and an air outlet for discharging the pyrolysis gas.
[0033] In one embodiment, see Figure 1As shown, the different regions of the material zone inside the magnetized pyrolysis gasification chamber 5 include two or more layered regions stacked from top to bottom. The air distribution duct 2 includes two or more air distribution duct groups composed of multiple air distribution ducts arranged corresponding to the layered regions of the material zone inside the magnetized pyrolysis gasification chamber 5. 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 duct group. The magnetization box 1 includes at least one chamber through which air passes. Each chamber's air inlet is equipped with a regulating valve 6. The air outlet of one chamber is connected to the air inlet c of one air distribution duct group. By adjusting the opening of the regulating valve 6, the amount of magnetized air entering the corresponding layered region can be adjusted.
[0034] The different areas of the material zone inside the magnetized pyrolysis gasification chamber 5 are divided by a layered division method. This is mainly based on the magnetized pyrolysis gasification reaction mechanism. The operating conditions of a single layered area are basically the same. The layered division method can effectively control the operating parameters of the corresponding area and facilitate the layout of the air distribution duct 2 and achieve precise control of the air distribution volume.
[0035] For example, see Figure 1 and Figure 3 As shown, the different regions of the material zone inside the magnetized pyrolysis gasification chamber 5 include two layered regions stacked from top to bottom, namely the upper layered region 7 and the lower layered region 8. The air distribution duct 2 includes a first air distribution duct group 21 and a second air distribution duct group 22 arranged corresponding to the upper and lower layered regions of the material zone inside the magnetized pyrolysis gasification chamber 5. Magnetized air, i.e., magnetized gas containing 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 duct group 21, and magnetized air, i.e., magnetized gas containing 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 duct group 22.
[0036] See Figure 3 As shown, there is one magnetization box 1, and each magnetization box 1 includes two independent air-carrying chambers, namely a first chamber 11 and a second chamber 12. The air inlets of the first chamber 11 and the second chamber 12 are connected to an air source, and a regulating valve 6 is arranged at the air inlet position of each air-carrying chamber. The air outlet of the first chamber 11 is connected to the air inlet of the first air distribution duct group 21, and the air outlet of the second chamber 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 may be at least two magnetization boxes 1, each containing a chamber through which air passes. One part of the chamber of the magnetization box 1 is connected to the air inlet of the first air distribution duct group 21, and the magnetized air is delivered to the upper layered area of the magnetization pyrolysis gasification chamber 5 through the air outlet of the first air distribution duct group 21. The other part of the chamber of the magnetization box 1 is connected to the air inlet of the second air distribution duct group 22, and the magnetized air is delivered to the lower layered area of the magnetization pyrolysis gasification chamber 5 through the air outlet of the second air distribution duct group 22.
[0038] Based on actual application requirements, the number of chambers through which air passes in the magnetization box 1 is reasonably arranged, and the chambers are connected to the corresponding air distribution duct groups to ensure the air supply needs of different areas of the material zone inside the magnetization pyrolysis gasification chamber 5.
[0039] In one embodiment, see Figure 1 and Figure 3 As shown, each layered region corresponds to an air distribution duct group including at least one lateral air distribution duct 23 arranged on the side wall of the magnetized pyrolysis gasification chamber 5 and / or at least one internal air distribution duct 24 arranged inside the magnetized pyrolysis gasification chamber 5 with its air outlet inside the corresponding layered region. Magnetized air is delivered from the side to the corresponding layered region through the air outlet of the lateral air distribution duct 23, and magnetized air is delivered to the material around the air outlet of the internal air distribution duct 24 in the corresponding layered region through the air outlet of the internal air distribution duct 24.
[0040] Taking the upper and lower layered regions as an example, the first air distribution duct group 21 corresponding to the upper layered region 7 includes at least one first lateral air distribution duct 231 arranged on the side wall of the magnetized pyrolysis gasification chamber 5 and at least one first internal air distribution duct 241 arranged inside the magnetized pyrolysis gasification chamber 5. The air inlet of the first lateral air distribution duct 231 is connected to the air outlet of the first chamber 11 of the magnetization box 1. The air outlet of the first lateral air distribution duct 231 extends into the magnetized pyrolysis gasification chamber 5 and faces the upper layered region 7 of the internal material area. Magnetized air is transported to the upper layered region 7 of the material area corresponding to the air outlet through the air outlet of the first lateral air distribution duct 231. That is, magnetized air is transported from the side to the upper layered region 7 through the air outlet of the first lateral air distribution duct 231.
[0041] The air inlet of the first internal air distribution duct 241 is connected to the air outlet of the first chamber 11 of the magnetization box 1. The air outlet of the first internal air distribution duct 241 extends into the magnetization pyrolysis gasification chamber 5 and faces the upper layered region 7 of the internal material area. Magnetized air is delivered to the upper layered region 7 of the material area corresponding to the air outlet through the air outlet of the first internal air distribution duct 241. That is, magnetized air is delivered to the material around the air outlet through the air outlet of the first internal air distribution duct 241 in the corresponding layered region.
[0042] The first lateral air distribution duct 231 meets the air supply requirements of the outer perimeter of the upper layered region 7 of the material zone, while the first internal air distribution duct 241 extends into the upper layered region 7 of the material zone, ensuring sufficient contact between the material and the magnetized air. This avoids insufficient contact between the material and the magnetized air in local areas, especially in the middle of the upper layered region 7, which would affect the uniformity and stability of magnetization pyrolysis gasification. Through the synergistic effect of the first lateral air distribution duct 231 and the first internal air distribution duct 241, the thermomagnetic gasification reaction in the entire upper layered region 7 is effectively guaranteed, improving the uniformity and efficiency of material pyrolysis in each region.
[0043] Similarly, the second air distribution duct group 22 corresponding to the lower layered region 8 includes at least one second lateral air distribution duct 232 arranged on the side wall of the magnetized pyrolysis gasification chamber 5 and at least one second internal air distribution duct 242 arranged inside the magnetized pyrolysis gasification chamber 5.
[0044] The air inlet of the second lateral air distribution duct 232 is connected to the air outlet of the second chamber 12 of the magnetization box 1. The air outlet of the second lateral air distribution duct 232 extends into the magnetization pyrolysis gasification chamber 5 and faces the lower layered region 8 of the internal material area. Magnetized air is delivered to the lower layered region 8 of the material area corresponding to the air outlet through the air outlet of the second lateral air distribution duct 232. That is, magnetized air is delivered from the side to the lower layered region 8 through the air outlet of the second lateral air distribution duct 232.
[0045] The air inlet of the second internal air distribution duct 242 is connected to the air outlet of the second chamber 12 of the magnetization box 1. The air outlet of the second internal air distribution duct 242 extends into the magnetization pyrolysis gasification chamber 5 and faces the lower layered region 8 of the internal material area. Magnetized air is delivered to the lower layered region 8 of the material area corresponding to the air outlet through the air outlet of the second internal air distribution duct 242. That is, magnetized air is delivered to the material around the air outlet through the air outlet of the second internal air distribution duct 242 in the corresponding layered region.
[0046] For example, the second internal air distribution duct 242 includes at least one vertical internal air distribution duct 2421 arranged vertically in the magnetized pyrolysis gasification chamber 5 and at least one horizontal air distribution duct 2422 arranged horizontally in the lower part of the magnetized pyrolysis gasification chamber 5.
[0047] In one embodiment, please refer to Figure 1 As shown, the parameter acquisition element 3 includes a temperature acquisition element 31 for acquiring the temperature of different areas of the magnetized pyrolysis gasification chamber. The controller 4 acquires the temperature of different areas of the magnetized pyrolysis gasification chamber 5 acquired by the temperature acquisition element 31, calculates the target opening degree of the regulating valve 6 corresponding to different areas, and controls the regulating valve 6 to operate to the target opening degree, thereby realizing the automatic adjustment of the air intake of each area.
[0048] Specifically, the controller 4 adjusts the opening of the regulating valve 6 of the corresponding magnetization box 1 based on the real-time temperature collected by the temperature acquisition 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. This allows the pyrolysis reaction rate and temperature of different areas of the corresponding material zone to be adjusted by regulating the air intake of the magnetized air.
[0049] For example, the regulating valve 6 has different opening levels, such as 0% (completely closed), 20%, 50%, 80%, and 100% (completely open). Taking the upper and lower layered regions as an example, the number of chambers through which the oxygen-carrying gas passes in the magnetization box 1 is two, namely the first chamber 11 and the second chamber 12. The different opening levels of the regulating valve 6 can change the air intake of the first chamber 11 and the second chamber 12. It is worth noting that the above-mentioned levels of the regulating valve 6 are only examples and not limitations; other technical solutions can also be used. The following further illustrates this embodiment: Temperature data from the temperature acquisition element 31 is acquired at certain intervals or in real time. When the acquired temperature is higher than a preset threshold, the opening of the regulating valve 6 is reduced (e.g., from 80% to 50%) to reduce the air intake of the first chamber 11 or the second chamber 12. If the temperature data acquired after reducing the opening of the regulating valve 6 is still higher than the preset threshold, the opening of the regulating valve 6 is further reduced until it is completely closed. When the collected temperature is lower than the preset threshold, the control valve 6 is opened more (e.g., from 50% to 80%) to increase the air intake of the first compartment 11 or the second compartment 12. If the temperature data collected next time is still lower than the preset threshold after the control valve 6 is opened more, the control valve 6 is opened more until it is fully open.
[0050] In one embodiment, please refer to Figure 1 As shown, the parameter acquisition element 3 further includes an oxygen content sensor 32 arranged above the material zone or in the pyrolysis gas discharge channel, which acquires the oxygen content of the pyrolysis gas. For example, the oxygen content sensor 32 is arranged above the material zone.
[0051] If the oxygen content sensor 32 detects that the oxygen content above the material zone exceeds a preset threshold, a feeding operation is performed to add new material or / and the control valve 6 is reduced in opening.
[0052] The controller 4 acquires temperature data collected by temperature acquisition element 31 and oxygen content data of pyrolysis gas collected by oxygen content sensor 32. It analyzes the temperature and rate of pyrolysis gasification reaction in different areas of magnetized pyrolysis gasification chamber 5, calculates the target opening degree of regulating valve 6 for different areas, and controls regulating valve 6 to operate to the target opening degree. This achieves automatic adjustment of the air volume of magnetized gas with oxygen in each area, thereby achieving adjustment of the pyrolysis gasification temperature and rate in each area, as well as the residual oxygen content in the generated pyrolysis gas.
[0053] When the temperature data and oxygen content data acquired by the controller 4 conflict, the target opening of the regulating valve 6 is set preferentially based on the oxygen content data. For example, when the collected temperature is below a preset threshold and the collected oxygen content of the pyrolysis gas exceeds a preset value, the controller needs to increase the opening of the regulating valve 6 when the temperature is below the preset threshold, and decrease the opening when the oxygen content exceeds the preset value, which contradicts the increase in opening based on the temperature data. In this case, the control logic prioritizes the oxygen content data, meaning the output action is to decrease the opening of the regulating valve 6.
[0054] In one embodiment, the number of magnetization boxes 1 is two or more, and they are evenly spaced along the circumference of the magnetization pyrolysis gasification chamber 5. Please refer to [link to relevant documentation]. Figure 2 As shown, for example, there are four magnetization boxes 1, which are evenly spaced around the periphery of the magnetization pyrolysis gasification chamber 5.
[0055] For example, when the number of layered regions distributed from top to bottom is small, such as two or three, each magnetization box 1 is provided with an air-carrying chamber corresponding to the number of layered regions. One air-carrying chamber corresponds to one layered region, and the two are connected by at least one air distribution duct group. When the number of layered regions distributed from top to bottom is large, such as three or more, each magnetization box is provided with one or two air-carrying chambers. Multiple magnetization boxes 1 are used in combination to connect the air-carrying chambers to the corresponding layered regions through at least one air distribution duct group.
[0056] Furthermore, given the unstable sources of medical waste and maintenance needs, the equipment requires multiple operating conditions, including normal operation, low-load operation, and shutdown, with manual and automatic switching between these conditions. Therefore, the automatic air distribution system used in the thermomagnetic gasification unit can also automatically execute different control logics according to different operating conditions.
[0057] When the equipment 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.
