Description

Technical Field

[0001] This invention relates to the field of gasification furnace technology, specifically a multi-channel flow-guided melting gasification furnace. Background Technology

[0002] Molten gasifiers are crucial core equipment in modern coal chemical and metallurgical industries. They are mainly used to convert coal or its derivatives into syngas or to smelt and reduce iron ore for ironmaking. The level of technological development directly affects energy conversion efficiency, raw material adaptability, environmental performance, and the economics of the final product. Although traditional fixed-bed and fluidized-bed gasification technologies are mature, they have many limitations in processing high-ash and high-ash-melting-point coals or achieving large-scale, high-efficiency operation. In particular, for the gasification process with liquid slag discharge, the uniformity of the flow field inside the furnace, the stability of the temperature distribution, and the smooth discharge of molten slag are key to ensuring the long-term, safe, and efficient operation of the equipment.

[0003] Common flow-guided melting gasifiers rely on fixed ventilation structures and lack adjustable flow-guided and wind-blocking components. This results in a lack of control over the combustion and gasification systems, low efficiency, rigid support and heating status adjustments, poor adaptability, insufficient coverage of application scenarios, weak versatility, and an inability to adapt to combustion requirements by adjusting oxygen supply, leading to a narrow range of feedstock applicability. To address this, we propose a multi-channel flow-guided melting gasifier. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-channel flow-guided melting gasification furnace.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-channel flow-guiding type molten gasification furnace, comprising a gasification furnace and a fire-gathering hood at the upper end of the gasification furnace. The upper end of the fire-gathering hood is connected to a wind baffle for blocking wind. The upper end of the wind baffle is provided with a flow-guiding port for guiding flow. The upper end of the flow-guiding port is movably connected to a movable plate for adjusting the size of the flow-guiding port. The upper end of the fire-gathering hood is provided with a mounting groove. A rotating rod is rotatably connected to the side wall of the mounting groove. A gas support frame with a supporting effect is connected to the outer wall of the rotating rod. The lower end of the fire-gathering hood is connected to a lifting block for controlling the support angle of the gas support frame. The lower end of the fire-gathering hood is connected to a fixing frame for controlling the height position of the lifting block.

[0006] As a further aspect of the present invention: an arc-shaped telescopic groove is provided on the side of the wind deflector near the flap, and an arc-shaped frame for adjusting the position of the flap is movably connected to the inner wall of the arc-shaped telescopic groove.

[0007] As a further aspect of the present invention: the outer wall of the arc-shaped frame is connected to a control block for controlling the position of the arc-shaped frame, and the control block extends to the outside of the wind deflector.

[0008] As a further aspect of the present invention: two extension plates are connected to the side of the gas support away from the gasifier, and a first rotating shaft is rotatably connected to the side of the two extension plates that are close to each other.

[0009] As a further aspect of the present invention: the upper end of the lifting block is connected to two upper extension plates, and a second rotating shaft is rotatably connected between the two upper extension plates. The outer wall of the first rotating shaft is rotatably connected to a connecting plate for rotatably connecting the second rotating shaft.

[0010] As a further aspect of the present invention: two translation slots are provided on the side of the lifting block away from the gasifier, and external through holes are provided on the side of the two translation slots that are far apart from each other.

[0011] As a further aspect of the present invention: the inner wall of the translation groove is slidably connected with translation blocks for fixing the position of the lifting block, and the side of the two translation blocks that are far apart from each other is connected to the inner wall of the translation groove through a return spring.

[0012] As a further embodiment of the present invention: the upper end of the fixed frame is provided with a lifting groove, the inner wall of the lifting groove is slidably connected to the outer wall of the lifting block, and the side wall of the lifting groove is provided with a fixing hole for cooperating with the translation block to form a fixed position.

[0013] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:

[0014] 1. This invention balances the internal air pressure after the baffle plate blocks the airflow through the guide port, avoiding incomplete combustion caused by lack of airflow. With the adjustable plate, the size of the guide port can be flexibly adjusted to precisely adapt to the oxygen supply requirements of different combustion intensities, ensuring stable and efficient combustion and gasification reactions. The gas support frame can be precisely adjusted in terms of support angle through the lifting block and the fixed frame, which can adjust the contact state between the pot and the flame as needed, optimize heating efficiency and energy saving, adapt to different cooking scenarios, ensure that the equipment is placed stably in various environments, reduce the risk of tipping over, and the adjustable design of the adjustable plate makes the equipment adaptable to the use requirements of different raw materials and different combustion power, thus having a wider range of applications.

[0015] 2. This invention achieves linear adjustment of the size of the air guide by controlling the sliding of the arc-shaped frame through the control block, precisely controlling the air intake volume, adapting to different combustion intensity requirements, ensuring complete fuel combustion, and improving combustion efficiency. The crank-slider structure converts the linear motion of the lifting block into the rotational motion of the air support, achieving flexible and stable adjustment of the support angle. The drive design of the control block and the lifting block makes the adjustment of the air guide and the adjustment of the air support angle both achieved through simple operation, without complicated steps, thus improving ease of use.

[0016] 3. The present invention can firmly fix the lifting block at the target height through the interlocking structure of the translation block and the fixing hole, so that the gas support can stably maintain the preset support angle and prevent the gasifier from tipping over due to loose support. The translation block can be quickly unlocked by pressing the external through hole, and it can be automatically reset and fixed after adjustment by releasing it. No tools are required to achieve rapid adjustment of the height of the lifting block.

[0025] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0026] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Example 1

[0028] This invention relates to a multi-channel guided flow molten gasifier. In modern coal chemical and metallurgical industrial production, it is often necessary to process coals with high ash content and high ash melting point. Traditional gasifiers suffer from problems such as uneven flow field inside the furnace, unstable temperature distribution, and poor slag discharge. Moreover, the fixed ventilation structure cannot adapt to the combustion requirements of different raw materials, resulting in low combustion and gasification efficiency, narrow raw material applicability, and rigid equipment support with insufficient coverage of application scenarios. In this case, the multi-channel guided flow molten gasifier can block external interference with its baffle plate. The combination of the movable plate and the arc frame can accurately adjust the size of the guide port to adapt to the oxygen supply requirements of different combustion intensities. The gas support frame can flexibly adjust the support angle through the lifting block and the fixed frame to ensure stable placement of the equipment. The combination of the translation block and the return spring can quickly fix or adjust the height of the lifting block. At the same time, the crank-slider structure makes operation more convenient.

[0029] Therefore, in order to effectively solve the above problems, this application proposes a multi-channel guided flow type molten gasification furnace, as shown in the attached drawings of the specification. Figure 1-6 As shown, the device includes a gasifier 1 and a fire-gathering hood 11 at the upper end of the gasifier 1. The upper end of the fire-gathering hood 11 is connected to a wind baffle 2 for blocking wind. The upper end of the wind baffle 2 is provided with a flow guide for guiding the flow. The upper end of the flow guide is movably connected to a hinged plate 21 for adjusting the size of the flow guide. The upper end of the fire-gathering hood 11 is provided with a mounting groove. The side wall of the mounting groove is rotatably connected to a rotating rod 23. The outer wall of the rotating rod 23 is connected to a gas support frame 22 with a supporting effect. The lower end of the fire-gathering hood 11 is connected to a lifting block 25 for controlling the support angle of the gas support frame 22. The lower end of the fire-gathering hood 11 is connected to a fixing frame 24 for controlling the height position of the lifting block 25.

[0030] Meanwhile, the height of the arc frame 31 is lower than that of the wind deflector 2, thus forming a multi-channel airflow with the guide port. Furthermore, the height of the arc frame 31 is variable and can be adjusted during manufacturing as needed to increase the size of the channel and thus adjust the airflow effect.

[0031] Specifically, the flame-gathering cover 11 is installed on the upper part of the gasifier 1. Its core function is to concentrate the flame, reduce heat loss, and increase the local combustion temperature.

[0032] The wind deflector 2 is connected to the upper end of the flame-gathering cover 11, directly blocking the external wind force to prevent the wind from interfering with the stability of the flame, and at the same time providing an installation base for the airflow guiding structure;

[0033] The air guide serves as an airflow channel to balance the internal air pressure after being blocked by the wind baffle 2, thus preventing incomplete combustion due to lack of airflow.

[0034] The flap 21 is movably connected to the upper end of the guide port. By adjusting its own opening and closing angle, the actual size of the guide port can be changed, flexibly controlling the airflow and adapting to the oxygen supply requirements under different combustion intensities.

[0035] The rotating rod 23 is rotatably connected to the side wall of the mounting groove, serving as the fulcrum for the rotation of the air support 22, allowing the air support 22 to adjust its support angle around it.

[0036] The gas support frame 22 is connected to the outer wall of the rotating rod 23 and has a supporting function. By adjusting the angle, it can be adapted to different placement scenarios, thereby enhancing the overall stability of the gasifier 1.

[0037] The fixed frame 24 is connected to the lower end of the fire-collecting cover 11, providing installation and movement guidance for the lifting block 25, ensuring that the height of the lifting block 25 is adjusted along a fixed trajectory;

[0038] The lifting block 25 is connected to the lower end of the fire-gathering cover 11 and cooperates with the fixed frame 24. By changing its own height, it pushes the gas support frame 22 to rotate around the rotating rod 23, thereby precisely controlling the support angle of the gas support frame 22 to achieve stable support or folding.

[0039] When the gasifier 1 is working, the flame-gathering hood 11 gathers the flame, the baffle 2 blocks external wind interference, the flap 21 adjusts the size of the guide port to control the oxygen supply, and at the same time the height of the lifting block 25 is adjusted by the fixed frame 24, thereby adjusting the distance between the support and the flame, driving the gas support frame 22 to rotate around the rotating rod 23 to a suitable support angle to ensure that the equipment is placed stably.

[0040] Example 2

[0041] The wind deflector 2 has an arc-shaped telescopic groove 3 on the side near the flap 21, and an arc-shaped frame 31 for adjusting the position of the flap 21 is movably connected to the inner wall of the arc-shaped telescopic groove 3.

[0042] The outer wall of the arc frame 31 is connected to a control block 32 for controlling the position of the arc frame 31, and the control block 32 extends to the outside of the wind deflector 2;

[0043] The side of the gas support 22 away from the gasifier 1 is connected to two extension plates 4, and the side of the two extension plates 4 that are close to each other is rotatably connected to a first rotating shaft.

[0044] The upper end of the lifting block 25 is connected to two upper extension plates 42, and a second rotating shaft is rotatably connected between the two upper extension plates 42. The outer wall of the first rotating shaft is rotatably connected to a connecting plate 41 for rotatably connecting the second rotating shaft.

[0045] Adjustment mechanism: The sliding mechanism composed of control block 32 and arc frame 31 realizes linear and precise adjustment of the size of the guide orifice, thus optimizing combustion efficiency;

[0046] The support frame 22 adjustment mechanism: Through the crank-slider mechanism composed of the lifting block 25, connecting rod and extension plate 4, the linear motion of the lifting block 25 is cleverly converted into the rotational motion of the support frame 22, realizing flexible and stable adjustment of the support angle;

[0047] The drive device controls the lifting block 25 to move up and down along the fixed frame 24. The lifting block 25 drives the upper extension plate 42 and the second rotating shaft to rise and fall synchronously. The second rotating shaft pulls or pushes the first rotating shaft through the connecting rod. The first rotating shaft drives the extension plate 4 and the entire air support frame 22 to rotate around the rotating rod 23 at its root. The support angle of the air support frame 22 changes, realizing stable support height adjustment.

[0048] Example 3

[0049] Two translation slots 43 are provided on the side of the lifting block 25 away from the gasifier 1, and external through holes 46 are provided on the side of the two translation slots 43 that are far away from each other.

[0050] The inner wall of the translation groove 43 is slidably connected with translation blocks 44 for fixing the position of the lifting block 25. The side of the two translation blocks 44 that are far apart from each other is connected to the inner wall of the translation groove 43 through a return spring 45.

[0051] The upper end of the fixed frame 24 is provided with a lifting groove, the inner wall of the lifting groove is slidably connected to the outer wall of the lifting block 25, and the side wall of the lifting groove is provided with a fixing hole for cooperating with the translation block 44 to form a fixed position.

[0052] Unlocking and Adjustment: When the height of the lifting block 25 needs to be adjusted, press the two sliding blocks 44 on both sides inward through the outer through hole 46. The sliding blocks 44 compress the reset spring 45 and retract into the sliding groove 43, disengaging from the locking hole. The lifting block 25 is unlocked and can slide up and down along the lifting groove to adjust its position.

[0053] Fixed positioning: After adjusting the lifting block 25 to the target height, release the translation block 44, the reset spring 45 returns to its natural extension state, push the translation block 44 outward and insert it into the corresponding fixing hole on the side wall of the lifting groove, the lifting block 25 is fixed and its height position remains unchanged;

[0054] After the lifting block 25 is fixed, the linkage mechanism drives the gas support frame 22 to maintain the current support angle, ensuring that the gasifier 1 is placed stably. The height of the lifting block 25 can be adjusted again to change the support angle of the gas support frame 22 simultaneously.

[0055] The terms "front," "back," "left," "right," "top," and "bottom" all refer to the figures in the accompanying drawings. Figure 1 Based on.

[0056] In the description of this invention, it should be understood that the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.

[0058] For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
