Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, and in particular to an anaerobic dry distillation waste gasification furnace with a staged heating structure. Background Technology

[0002] Anaerobic pyrolysis waste gasification furnaces are advanced technologies used to treat municipal solid waste and biomass waste. Their basic principle is to isolate oxygen within a completely sealed furnace body, heating the waste at medium to low temperatures to decompose organic matter into combustible gases, liquid tar, and solid carbonaceous materials. A typical gasification furnace body is usually divided into a drying layer, a pyrolysis layer, a combustion layer, a reduction layer, and an ash layer from top to bottom to achieve the gradual transformation of waste. Before subsequent pyrolysis and gasification, the waste needs to be dehydrated in the drying layer. However, in existing technologies, the drying process is often integrated into the feeding process, and the feeding equipment often uses an open design. This design makes it easy for heat to dissipate during the drying process, resulting in high energy consumption in the drying stage. At the same time, the gasification furnace itself generates a large amount of waste heat during operation, but existing drying structures cannot effectively utilize this waste heat to dry the waste, resulting in energy waste. Therefore, how to improve the energy utilization efficiency of the drying process and fully utilize the waste heat generated by the gasification furnace itself is an urgent problem to be solved in the current field of anaerobic pyrolysis waste gasification furnace technology. To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0024] Anaerobic pyrolysis waste gasification furnaces, as advanced waste treatment equipment, heat waste at medium and low temperatures under oxygen-free conditions, converting it into energy substances such as combustible gases, liquid tar, and solid carbon deposits. Traditional gasification furnaces typically include multiple functional areas such as a drying layer and a pyrolysis layer. However, in existing technologies, the waste drying process is often integrated with the feeding process, and the feeding equipment often uses an open design, leading to easy heat loss during the drying process and high energy consumption. Simultaneously, the gasification furnace itself generates a large amount of waste heat during operation, which is not fully and effectively utilized, resulting in energy waste. To address the problems of high energy consumption in the drying process and insufficient waste heat utilization in existing technologies, this invention proposes an anaerobic pyrolysis waste gasification furnace with a staged heating structure. This gasification furnace achieves a highly efficient and low-consumption drying process by setting up independent drying chambers and heat exchange chambers, and utilizing a heat-conducting structure to transfer the waste heat from the gasification furnace itself to the waste in the drying chamber.

[0025] This utility model discloses an anaerobic dry distillation waste gasification furnace with a staged heating structure, mainly used for anaerobic dry distillation gasification of municipal solid waste, biomass waste, etc. The equipment completes the drying and pyrolysis processes of waste within a sealed furnace body. The gasification furnace body 1 is the area where the main gasification reaction takes place, generating high-temperature flue gas and waste heat. The drying chamber 4 is the area used to pre-dry the waste before it enters the gasification furnace body 1. The heat exchange chamber 9 is an intermediate structure located between the gasification furnace body 1 and the drying chamber 4, used to absorb the waste heat generated by the gasification furnace body 1 and transfer it to the drying chamber 4. Multiple heat-conducting plates 5 are installed in the drying chamber 4 to receive the heat transferred from the heat exchange chamber 9 and conduct it to the waste on it. A drive mechanism is used to drive the heat-conducting plates 5 to move, thereby moving the waste within the drying chamber 4. The feed inlet 3 is the channel through which the waste enters the drying chamber 4. The return gas pipe 10 is used to discharge the moisture generated during the drying process. The triangular outlet 11 is the outlet for the dried waste from the drying chamber 4 into the gasification furnace body 1.

[0026] Specifically, the gasifier includes a gasifier body 1. See also... Figure 1 A heat exchange chamber 9 is fixedly connected to the upper side wall of the gasifier body 1, and a drying assembly is also fixedly connected to the upper side wall of the gasifier body 1. The drying assembly is located above the heat exchange chamber 9 and has a feed inlet 3. As one possible implementation, the drying assembly may include a drying chamber 4 fixedly connected to the gasifier body 1. The drying chamber 4 may have a ring-shaped structure, with internal structures for carrying and moving waste. The heat exchange chamber 9 may be arranged around the upper part of the gasifier body 1 to maximize the absorption of waste heat emitted by the gasifier body 1. The feed inlet 3 may be located at the top of the drying chamber 4 for convenient feeding of pre-treated waste into the drying chamber 4.

[0027] Multiple heat-conducting plates 5 are installed inside the drying chamber 4. (See also...) Figure 3 and Figure 5 These heat-conducting plates 5 can be arranged around the heat exchange chamber 9 and mounted on its upper cover. After absorbing the waste heat from the gasifier body 1, the temperature of the upper cover of the heat exchange chamber 9 rises, and the heat is transferred to the heat-conducting plates 5 through contact with them. The heat-conducting plates 5 are made of materials with good thermal conductivity, such as metal, so that they can effectively conduct heat to the waste above them, achieving the heating and drying of the waste. In order to move the waste in the drying chamber 4 and receive uniform heating, a drive mechanism is provided to drive these heat-conducting plates 5 to rotate. This drive mechanism can include, but is not limited to, motors, reducers, and transmission elements such as transmission chains, belts, or gears. Through the cooperation of these elements, the heat-conducting plates 5 rotate along a circular path. For example, a drive motor 6 can be provided, which drives a gear ring 8 connected to the heat-conducting plate 5 to rotate through a drive gear 7, thereby realizing the overall rotation of the heat-conducting plates 5.

[0028] See Figure 1 and Figure 2 A return air pipe 10 is also installed at the top of the drying chamber 4. During the waste drying process, the moisture in the waste evaporates to produce water vapor. This return air pipe 10 is used to extract the water vapor generated in the drying chamber 4, preventing it from entering the subsequent gasification process and affecting gasification efficiency. Simultaneously, the extracted water vapor can be recycled, which is beneficial to environmental protection. See also Figure 4 and Figure 5 A triangular opening 11 is provided at the bottom of the drying chamber 4. After the waste rotates on the heat-conducting plate 5 and is dried, it needs to be sent to the gasifier body 1 below for gasification. The triangular opening 11 is the channel through which the dried waste is discharged from the drying chamber 4 to the gasifier body 1.

[0029] Compared with existing technologies, this invention separates the drying process and incorporates a heat exchange chamber 9 and a heat-conducting plate 5, forming a highly efficient waste heat utilization drying system. In existing technologies, the drying process is integrated with the feeding process and is often open, resulting in significant heat loss and high energy consumption. This invention utilizes the waste heat generated by the gasifier body 1 as the drying heat source, transferring heat through the heat exchange chamber 9 and the heat-conducting plate 5, significantly reducing external energy consumption during the drying process and improving the overall energy efficiency of the equipment. Furthermore, the independently designed drying chamber 4 and return gas pipe 10 allow for better control of the drying process and timely discharge of water vapor, preventing adverse effects on subsequent gasification processes. This staged heating structure ensures that the waste is fully dried before entering the gasifier body 1, which is beneficial for improving the efficiency of subsequent gasification reactions and the quality of gas produced.

[0030] During operation, pre-treated waste is fed into the drying chamber 4 through the feed inlet 3 and falls onto multiple heat-conducting plates 5. Waste heat generated during the operation of the gasifier body 1 is absorbed by the heat exchange chamber 9. The heat exchange chamber 9 transfers heat to the heat-conducting plates 5 mounted on its upper cover. The drive mechanism is activated, driving the heat-conducting plates 5 to rotate along a circular path, moving the waste along with them. As the waste moves with the heat-conducting plates 5, it continuously receives heat conducted from them, and the internal moisture gradually evaporates. The generated water vapor is extracted through the return air pipe 10 located at the top of the drying chamber 4. When the waste rotates with the heat-conducting plates 5 to above the triangular opening 11, the structure or movement of the heat-conducting plates 5 changes (e.g., tilting or increasing the gap between plates), allowing the dried waste to smoothly slide off the heat-conducting plates 5 or fall through the gaps into the triangular opening 11 below, ultimately entering the gasifier body 1 for subsequent gasification treatment. In this process, the gasifier body 1 provides the heat source, the heat exchange chamber 9 and the heat conduction plate 5 form an efficient heat transfer path, the drying chamber 4 provides the drying space, the drive mechanism enables continuous movement of the waste, the return gas pipe 10 removes moisture, and the triangular outlet 11 completes the discharge of the dried waste. The entire process makes full use of the waste heat of the gasifier, achieves effective pre-drying of the waste, and improves the overall processing efficiency and energy utilization rate.

[0031] Furthermore, this application also proposes that the drying assembly includes a drying chamber fixedly connected to the gasifier body, a gear ring rotatably connected inside the drying chamber, a plurality of heat-conducting plates arranged in a ring rotatably connected to the inner wall of the gear ring, a drive motor fixedly connected inside the drying chamber, a drive gear meshing with the gear ring being driven at the lower end of the drive motor, a groove being provided on the upper surface of the heat exchange chamber, a guide shell being fixedly connected inside the groove, and a triangular opening being provided on the side of the gasifier body near the guide shell.

[0032] See Figure 2 , Figure 3 and Figure 4 In one specific embodiment, the drying assembly may include a drying chamber 4 fixedly connected to the gasifier body 1. The drying chamber 4 contains a mechanism for driving the rotation of the heat-conducting plates 5 and a structure for guiding waste discharge. Specifically, a geared ring 8 is rotatably connected within the drying chamber 4, and multiple surrounding heat-conducting plates 5 are rotatably connected to the inner wall of the geared ring 8. This means that the heat-conducting plates 5 can rotate or oscillate relative to the geared ring 8 within a certain range. To drive the rotation of the geared ring 8, a drive motor 6 is provided, which is fixedly connected within the drying chamber 4. Its output shaft meshes with the geared ring 8 via a drive gear 7. When the drive motor 6 is running, the drive gear 7 drives the geared ring 8 to rotate, which in turn drives the heat-conducting plates 5 to rotate along a circular path via the rotatable connection.

[0033] The upper surface of the heat exchange chamber 9 is provided with a groove, and a guide shell 12 is fixedly connected within the groove. (See also...) Figure 4 and Figure 5 The guide shell 12 is located in a specific area on the top cover of the heat exchange chamber 9. Its inner wall has a certain shape or angle to guide the heat-conducting plate 5 when it rotates to this area. A triangular opening 11 is provided on the side of the gasifier body 1 near the guide shell 12. This triangular opening 11 is the channel for the dried waste to enter the gasifier body 1 from the drying chamber 4. When the heat-conducting plate 5 rotates to the area of ​​the guide shell 12, under the guidance of the guide shell 12, the angle of the heat-conducting plate 5 will change or the gap between the plates will increase, so that the waste on it can fall smoothly into the gasifier body 1 through the triangular opening 11.

[0034] By employing a combination of drive motor 6, drive gear 7, and gear ring 8, a reliable and easily controllable drive method is provided, ensuring the stable rotation of the heat-conducting plate 5. Simultaneously, by setting a trough with a guide shell 12 on the upper surface of the heat exchange chamber 9, and cooperating with the triangular opening 11 located on the side wall of the gasifier body 1, an effective automatic waste discharge structure is formed. When the heat-conducting plate 5 rotates to the area of ​​the guide shell 12, the guide shell 12 forcibly changes the state of the heat-conducting plate 5, allowing the dried waste to be effectively unloaded into the triangular opening 11, thereby achieving continuous or intermittent discharge of dried waste. This specific structural design makes the entire drying and discharge process smoother and more automated, improving the operating efficiency and reliability of the equipment.

[0035] Furthermore, this application also proposes multiple heat-conducting plates that are rotatably connected to the inner wall of the toothed ring.

[0036] See Figure 3 As a specific connection method, the multiple heat-conducting plates 5 are rotatably connected to the inner wall of the toothed ring 8. This means that one end or side of each heat-conducting plate 5 is connected to the inner wall of the toothed ring 8 through some rotatable structure. For example, it can be achieved by a pin, hinge, or other form of pivoting connection. This rotatable connection allows the heat-conducting plate 5 to rotate or swing freely relative to the toothed ring 8 within a certain angle range, while at the same time being firmly driven by the toothed ring 8 to perform overall circular motion.

[0037] This technical solution further defines the connection between the heat-conducting plate 5 and the gear ring 8 that drives its rotation. By employing a rotating connection instead of a fixed connection, it ensures that when the gear ring 8 is driven to rotate by the drive mechanism, it can reliably drive the multiple heat-conducting plates 5 connected to it to rotate together. This connection method ensures the stable movement of waste on the heat-conducting plate 5, allowing the waste to be heated and dried along a predetermined path within the drying chamber 4. This rotating connection is the basis for realizing the overall rotation of the heat-conducting plate 5 and bearing the movement of waste, providing a reliable motion platform for the subsequent waste discharge mechanism.

[0038] Furthermore, this application also proposes that multiple heat-conducting plates remain horizontal under the support of the heat exchange chamber cover when they are located away from the triangular opening.

[0039] See Figure 3 and Figure 4 The multiple heat-conducting plates 5 rotate along a circular path within the drying chamber 4. In most areas, i.e., away from the triangular opening 11, the lower surfaces of these heat-conducting plates 5 rest on the upper cover of the heat exchange chamber 9. The upper cover of the heat exchange chamber 9 provides a flat support surface in this area, allowing the heat-conducting plates 5 to be placed stably and kept horizontal. This horizontal position ensures that the waste remains stably on the heat-conducting plates 5 and does not slip prematurely due to tilting.

[0040] This technical solution defines the working state of the heat-conducting plate 5 during the drying and heating process. By utilizing the upper cover of the heat exchange chamber 9 as a support, the heat-conducting plate 5 remains horizontal in most of the rotation area, which is crucial for the retention of waste on the heat-conducting plate 5 and for sufficient heating and drying. The horizontal heat-conducting plate 5 can stably support the waste and ensure that the waste receives heat from the heat exchange chamber 9 evenly throughout the entire rotation process, thereby improving drying efficiency and effectiveness.

[0041] Furthermore, this application also proposes that a guide shell be provided inside the drying chamber, with a triangular opening located below the inner wall of the guide shell.

[0042] See Figure 4 and Figure 5 Inside the drying chamber 4, particularly in the area near the triangular opening 11, a guide shell 12 is provided. This guide shell 12 is fixedly connected to a groove on the upper surface of the heat exchange chamber 9 and extends upwards into the drying chamber 4. The guide shell 12 has a specific shape and angle, and its inner wall forms a guiding surface. The triangular opening 11 is located below the inner wall of the guide shell 12, i.e., below the area defined by the guide shell 12, and communicates with the gasifier body 1.

[0043] This technical solution further defines the structural layout of the waste discharge area. By setting a guide shell 12 inside the drying chamber 4, a precise guiding path is provided for the rotating heat-conducting plate 5. When the heat-conducting plate 5 rotates to the area of ​​the guide shell 12, its movement is constrained and guided by the inner wall of the guide shell 12, thereby achieving a predetermined tilting or swinging action to unload the waste. A triangular opening 11 is set below the guide shell 12, forming a concentrated discharge area to ensure that the waste unloaded from the heat-conducting plate 5 can accurately fall into the gasifier body 1. This structural design makes the waste discharge process more controllable and efficient, avoiding the accumulation or scattering of waste in the discharge area.

[0044] Furthermore, this application also proposes that when multiple heat-conducting plates rotate to the guide shell, they rotate along the inner wall of the guide shell to an inclined state, and the gap between the multiple heat-conducting plates increases.

[0045] See Figure 5 When the multiple heat-conducting plates 5 rotate with the toothed ring 8 to the area where the guide shell 12 is located, because the heat-conducting plates 5 are rotatably connected to the toothed ring 8, and the inner wall of the guide shell 12 has a specific shape and angle, the lower surface or side of the heat-conducting plates 5 will contact and be guided by the inner wall of the guide shell 12. This guiding effect causes the heat-conducting plates 5 to no longer remain in a horizontal state, but to rotate or swing to an inclined state along the inner wall of the guide shell 12. At the same time, due to the rotation or swing of the heat-conducting plates 5, the gap between the multiple heat-conducting plates 5 that were originally closely arranged will become larger.

[0046] This technical solution details the key actions of the heat-conducting plate 5 in the waste discharge area. Guided by the guide shell 12, the heat-conducting plate 5 can accurately change from a horizontal to an inclined state, which facilitates the downward sliding of the waste above it under gravity. At the same time, the gaps between the heat-conducting plates 5 increase, providing more space for the smooth passage of waste and preventing it from getting stuck. This synergistic effect ensures that the dried waste can be efficiently and smoothly unloaded from the heat-conducting plate 5 and enter the gasifier body 1 through the triangular opening 11 below.

[0047] Furthermore, this application also proposes that multiple heat-conducting plates rotate back to a horizontal state after passing the guide shell.

[0048] See Figure 3 and Figure 4 As the multiple heat-conducting plates 5 rotate with the toothed ring 8, after passing through the guide shell 12 area and completing waste discharge, they continue to rotate along the annular path. After leaving the guide shell 12 area, the heat-conducting plates 5 are no longer constrained by the inner wall of the guide shell 12. Due to the rotational connection between the heat-conducting plates 5 and the toothed ring 8, and the supporting effect provided by the heat exchange chamber 9 cover in the non-discharge area, the heat-conducting plates 5 will rotate or swing back to a horizontal state again, relying on their own structure or gravity.

[0049] This technical solution defines the recovery state of the heat-conducting plate 5 after waste discharge. After passing the guide shell 12 area and unloading the waste, the heat-conducting plate 5 returns to a horizontal state, allowing it to be stably repositioned on the upper cover of the heat exchange chamber 9 and ready to receive the next batch of waste entering the drying chamber 4 from the feed inlet 3. This cyclical movement and state change of the heat-conducting plate 5 ensures the continuity and automation of the drying process.

[0050] Furthermore, this application also proposes a return gas pipe for recovering water vapor generated by the evaporation of moisture in the drying chamber.

[0051] See Figure 1 and Figure 2 A return air pipe 10 is installed at the top of the drying chamber 4. One end of the return air pipe 10 connects to the internal space of the drying chamber 4, and the other end connects to an external waste gas treatment or recovery system. During the process of heating and drying the waste in the drying chamber 4, the moisture in the waste evaporates and forms a humid and hot gas containing water vapor. The return air pipe 10 extracts this water vapor and other accompanying gases generated in the drying chamber 4 through ventilation or negative pressure.

[0052] This technical solution clarifies the function of the return gas pipe 10. By setting up the return gas pipe 10 and using it to recover the water vapor generated during the drying process, moisture can be effectively discharged from the drying chamber 4. This not only avoids a large amount of water vapor entering the subsequent gasifier body 1, thus affecting the efficiency of the gasification reaction and the quality of the gas produced, but also allows the recovered water vapor to be reused or discharged in compliance with standards after condensation, purification, and other treatments, which is beneficial to environmental protection and resource conservation.

[0053] Furthermore, this application also proposes that a heat insulation sleeve be installed inside the drying chamber, which covers the drive motor.

[0054] See Figure 1 Inside the drying chamber 4, a drive motor 6 is installed to drive the heat-conducting plate 5 to rotate. Because the drying chamber 4 contains a high-temperature environment, a heat insulation sleeve 13 is installed on its exterior to protect the drive motor 6 from the high temperatures. This heat insulation sleeve 13 completely or partially covers the drive motor 6, forming a heat insulation layer. The heat insulation sleeve 13 can be made of a high-temperature resistant material with good heat insulation properties, such as ceramic fiber, rock wool, or other composite heat insulation materials.

[0055] This technical solution incorporates a heat insulation jacket 13 to effectively protect the drive motor 6 from the high-temperature environment. The temperature inside the drying chamber 4 is high; if the drive motor 6 is exposed to this environment for an extended period, its performance and lifespan will be severely affected. By installing the heat insulation jacket 13, the heat transferred to the drive motor 6 can be significantly reduced, enabling it to operate stably within a suitable temperature range, thereby improving the reliability and lifespan of the equipment.

[0056] Furthermore, this application also proposes that the heat insulation sleeve is installed through the upper end of the drying chamber, and the upper end of the heat insulation sleeve is provided with an opening, and the output end of the drive motor is installed through the lower surface of the heat insulation sleeve and extends into the drying chamber.

[0057] See Figure 1In one specific installation method, the heat insulation sleeve 13 is installed inside the drying chamber 4 to cover the drive motor 6. The heat insulation sleeve 13 extends upward through the upper wall of the drying chamber 4, and has an opening at its upper end. The drive motor 6 can be installed on the upper part or outside of the heat insulation sleeve 13, and its output end (e.g., a rotating shaft) extends downward, penetrates the lower surface of the heat insulation sleeve 13, and enters the interior of the drying chamber 4 to connect with the drive gear 7.

[0058] This technical solution further defines the specific installation positions and methods of the heat insulation sleeve 13 and the drive motor 6. By having the heat insulation sleeve 13 penetrate through the upper end of the drying chamber 4 and extend upwards, the drive motor 6 can be positioned in a relatively low-temperature area above the drying chamber 4, thereby better protecting the motor from the high temperatures inside the drying chamber 4. An opening at the upper end of the heat insulation sleeve 13 facilitates the dissipation of heat generated by the drive motor 6, further ensuring the normal operation and lifespan of the motor. Simultaneously, the output end of the drive motor 6 extends into the drying chamber 4 through the lower surface of the heat insulation sleeve 13, ensuring that the driving force can be transmitted to the internal transmission mechanism (such as the drive gear 7 and gear ring 8) to drive the heat-conducting plate 5. This structural design effectively insulates heat while also considering the motor's heat dissipation requirements and power transmission needs.

[0059] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
