Description

Technical Field

[0001] This invention relates to the field of smoldering equipment technology, and specifically to a smoldering furnace with directional slag discharge. Background Technology

[0002] Smoldering is a flameless combustion phenomenon that typically produces smoke. When smoldering reactants undergo a smoldering reaction in a smoldering furnace, the smoldering surface gradually rises.

[0003] Since smoldering is a flameless combustion phenomenon, smoke is usually produced during the smoldering process, making the smoldering reaction surface difficult to observe. Furthermore, during smoldering, the smoldering reaction surface fluctuates due to factors such as slag removal and ventilation. This means that the smoldering reaction surface in some areas may be higher or lower than in other areas, resulting in uneven smoldering of the material. In some cases, an excessively high smoldering reaction surface in a localized area can burn through the furnace body.

[0004] However, current smoldering furnaces do not monitor the smoldering reaction surface, nor can they make local adjustments to the smoldering reaction surface. Summary of the Invention

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The following describes a directional slag discharge smoldering furnace according to an embodiment of the present invention with reference to the accompanying drawings.

[0029] The directional smoldering furnace of this invention includes: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the smoldering furnace body 1 comprises a fixed structure 2, multiple temperature detection devices 3, a display module, and a slag discharge bottom plate 4. The smoldering furnace body 1 has a smoldering reaction chamber 11 for the smoldering reaction to occur. The fixed structure 2 is horizontally positioned inside the smoldering reaction chamber 11, with a gap between the fixed structure 2 and the bottom of the smoldering reaction chamber 11. The temperature detection devices 3 are used to detect the temperature of the smoldering reactants; each temperature detection device 3 is located on the fixed structure 2, with multiple temperature detection devices 3 spaced apart. The display module is located outside the smoldering reaction chamber 11 and is electrically connected to each temperature detection device 3, displaying the detected temperature. The slag discharge bottom plate 4 is located at the bottom of the smoldering reaction chamber 11 and has multiple slag discharge structures 41 for slag discharge, with the multiple slag discharge structures 41 corresponding vertically to the multiple temperature detection devices 3.

[0030] During the smoldering reaction of the smoldering reactants in the smoldering reaction chamber 11, the smoldering reaction surface gradually rises from the bottom of the smoldering reaction chamber 11. Multiple temperature detection devices 3 detect the temperature of the smoldering reactants at different positions, and the display module displays the detected temperature of the temperature detection devices 3, thereby realizing the detection of the smoldering reaction surface and reflecting the position of the smoldering reaction surface.

[0031] When the smoldering reaction surface in a localized area is too high, the smoldering reaction surface in that area first passes through the fixed structure 2. When the smoldering reaction surface in that area passes through the fixed structure 2, the temperature detected by the temperature detection device 3 in that area on the display module is higher, while the temperature detected by the temperature detection device 3 in other areas on the display module is lower. The slag discharge structure 41 corresponding to the temperature detection device 3 is opened to discharge slag, causing the smoldering reaction surface in that area to decrease, thereby achieving localized adjustment of the smoldering reaction surface.

[0032] When the smoldering reaction surface in a local area is too low, the smoldering reaction surface in that area passes through the fixed structure 2. When the smoldering reaction surface in other areas passes through the fixed structure 2, the smoldering reaction surface in that area is located below the fixed structure 2. That is to say, the temperature detected by the temperature detection device 3 in that area is lower on the display module, while the temperature detection device 3 in other areas is higher on the display module. The slag discharge structure 41 corresponding to the temperature detection device 3 in other areas is opened to discharge slag, causing the smoldering reaction surface in other areas to drop, thereby achieving local adjustment of the smoldering reaction surface.

[0033] The smoldering furnace with directional slag discharge in this embodiment of the invention uses multiple temperature detection devices spaced at intervals on a fixed structure to detect the temperature of the smoldering reactants. The detected temperature is displayed by a display module, thereby reflecting the position of the smoldering reaction surface. Based on the position of the smoldering reaction surface, the corresponding slag discharge structure is opened to achieve local adjustment of the smoldering reaction surface.

[0034] In some embodiments, such as Figure 2 As shown, at least three temperature detection devices 3 are provided. The fixed structure 2 is arranged from the inside to the outside along the inner and outer directions of the main body 1 of the smoldering furnace, with an internal detection area 23, a middle detection area 24 and an external detection area 25. Temperature detection devices 3 are provided in the internal detection area 23, the middle detection area 24 and the external detection area 25.

[0035] The temperature detection device 3 located in the internal detection zone 23 can reflect the position of the smoldering reaction surface in the central area, the temperature detection device 3 located in the middle detection zone 24 can reflect the position of the middle part of the smoldering reaction surface, and the temperature detection device 3 located in the external detection zone 25 can reflect the position of the outside of the smoldering reaction surface.

[0036] Dividing the smoldering reaction surface into three parts for observation can provide an overall picture of its location.

[0037] In some embodiments, such as Figure 3 As shown, there are at least three slag discharge structures 41. At least one slag discharge structure 41 corresponds to the inner detection area 23 in the vertical direction, at least one slag discharge structure 41 corresponds to the middle detection area 24 in the vertical direction, and at least one slag discharge structure 41 corresponds to the outer detection area 25 in the vertical direction. That is to say, each of the inner detection area 23, the middle detection area 24 and the outer detection area 25 has at least one slag discharge structure 41 corresponding to it in the vertical direction.

[0038] When the position of the central area of ​​the smoldering reaction surface is too high, the slag discharge structure 41 corresponding to the internal detection area 23 in the vertical direction is opened to discharge slag and lower the position of the central area of ​​the smoldering reaction surface.

[0039] When the position of the middle part of the smoldering reaction surface is too high, the slag discharge structure 41 corresponding to the middle detection zone 24 in the vertical direction is opened to discharge slag and lower the position of the middle part of the smoldering reaction surface.

[0040] When the position of the outer side of the smoldering reaction surface is too high, the slag discharge structure 41 corresponding to the outer detection area 25 in the vertical direction is opened to discharge slag and lower the position of the outer side of the smoldering reaction surface.

[0041] Local slag removal is performed at the corresponding positions of the internal detection zone 23, the middle detection zone 24 and the external detection zone 25. This can efficiently locate the slag removal structure 41 that needs to be removed, adjust the smoldering reaction surface in a timely manner, and refine the slag removal area, making the local adjustment of the smoldering reaction surface more precise.

[0042] Specifically, such as Figure 3 As shown, the four slag discharge structures 41 correspond to the internal detection area 23 in the vertical direction, the four slag discharge structures 41 correspond to the middle detection area 24 in the vertical direction, and the four slag discharge structures 41 correspond to the external detection area 25 in the vertical direction, thus refining the slag discharge area and making the local adjustment of the smoldering reaction surface more precise.

[0043] In some embodiments, such as Figure 3 As shown, the slag discharge structure 41 includes a slag discharge hole 411 and a slag discharge baffle 412. The slag discharge hole 411 is disposed on the slag discharge bottom plate 4, and the slag discharge baffle 412 is rotatably disposed on the slag discharge bottom plate 4 to open and close the slag discharge hole 411.

[0044] When slag discharge is required, adjust the slag discharge baffle 412 to open the slag discharge hole 411 for slag discharge. After slag discharge is completed, adjust the slag discharge baffle 412 to close the slag discharge hole 411 to stop slag discharge.

[0045] In some embodiments, such as Figure 2 and Figure 4 As shown, the fixing structure 2 includes a first fixing rod 21. The length direction of the first fixing rod 21 is consistent with the first horizontal direction. The two ends of the first fixing rod 21 are connected to the inner wall of the smoldering reaction chamber 11. The first fixing rod 21 is provided with an internal detection area 23, a middle detection area 24 and an external detection area 25 in sequence from the inside to the outside along the inner and outer directions of the smoldering furnace body 1.

[0046] The first fixing rod 21 supports and fixes the temperature detection device 3 so that the temperature detection device 3 can be located in the internal detection area 23, the middle detection area 24 and the external detection area 25.

[0047] In some embodiments, the fixing structure 2 further includes a second fixing rod 22. The length direction of the second fixing rod 22 is consistent with the second horizontal direction. Both ends of the second fixing rod 22 are connected to the inner wall of the smoldering reaction chamber 11. The first fixing rod 21 and the second fixing rod 22 are intersecting. The first fixing rod 21 and the second fixing rod 22 are provided with an internal detection area 23, a middle detection area 24 and an external detection area 25 in sequence from the inside to the outside along the inner and outer directions of the smoldering furnace body 1.

[0048] The second fixing rod 22 supports and fixes the temperature detection device 3 so that the temperature detection device 3 can be located in the internal detection area 23, the middle detection area 24 and the external detection area 25.

[0049] In some embodiments, such as Figure 2 and Figure 4 As shown, multiple first fixing rods 21 and multiple second fixing rods 22 are provided. Multiple first fixing rods 21 are spaced apart in the second horizontal direction, and multiple second fixing rods 22 are spaced apart in the first horizontal direction, allowing the temperature detection device 3 to be installed at multiple positions on the horizontal plane. Figure 4 As shown, the first fixing rod 21 is provided with a first wire groove 211, and the second fixing rod 22 is provided with a second wire groove 221. The first wire groove 211 and the second wire groove 221 are interconnected. The temperature detection device 3 is a thermocouple 31. The thermocouple 31 is electrically connected to the display module through a wire. The wire is located in the first wire groove 211 and the second wire groove 221. The first wire groove 211 and the second wire groove 221 accommodate the wire to prevent the wire from being damaged.

[0050] Optionally, the first horizontal direction and the second horizontal direction are perpendicular to each other.

[0051] In some embodiments, the slag discharge bottom plate 4 is hinged to the smoldering furnace body 1 to close and open the bottom end of the smoldering reaction chamber 11.

[0052] When overall slag removal is required, adjust the slag removal bottom plate 4 to open the bottom of the smoldering reaction chamber 11 for slag removal. When overall slag removal is required, adjust the slag removal bottom plate 4 to close the bottom of the smoldering reaction chamber 11 to stop slag removal.

[0053] In some embodiments, such as Figure 2 As shown, multiple fixing structures 2 are provided, and the multiple fixing structures 2 are spaced apart in the vertical direction, which can detect multiple positions in the vertical direction and further reflect the position of the smoldering reaction surface in the vertical direction.

[0054] Specifically, such as Figure 4 As shown, there are two fixed structures 2.

[0055] In some embodiments, the smoldering furnace also includes multiple indicator lights, which correspond one-to-one with multiple temperature detection devices 3. Each indicator light is electrically connected to the corresponding temperature detection device 3. When the temperature detected by the temperature detection device 3 is greater than or equal to a preset value, the indicator light is turned on to alert the inspection personnel. The indicator light can more intuitively reflect the position of the smoldering reaction surface and reduce the amount of information that the inspection personnel need to observe.

[0056] In some embodiments, the smoldering furnace further includes an end cap 14, a heater 5, and a blower 6. The main body 1 of the smoldering furnace is provided with a vent 12, and the blower 6 is connected to the vent 12. The vent 12 is located at the bottom of the main body 1 of the smoldering furnace. The top of the smoldering reaction chamber 11 is used to add smoldering reactants. The end cap 14 is movably disposed on the main body 1 of the smoldering furnace to close or open the top of the smoldering reaction chamber 11. The end cap 14 is provided with a flue gas outlet 13. Both the vent 12 and the flue gas outlet 13 are connected to the smoldering reaction chamber 11. The heater 5 is located at the bottom of the smoldering reaction chamber 11 and above the vent 12.

[0057] When it is necessary to add smoldering reactant into the smoldering reaction chamber 11, the top of the smoldering reaction chamber 11 is opened through the end cap 14 so that the smoldering reactant can enter the smoldering reaction chamber 11 from the top of the smoldering reaction chamber 11. When it is necessary to stop adding smoldering reactant into the smoldering reaction chamber 11, the end cap 14 is closed at the top of the smoldering reaction chamber 11.

[0058] Ventilation port 12 is located at the bottom of the smoldering furnace body 1, and flue gas outlet 13 is provided on end cover 14. That is to say, flue gas outlet 13 is located at the top of the smoldering furnace body 1, so that the air in the smoldering reaction chamber 11 flows from bottom to top. The heat generated by the smoldering reaction of the smoldering reactants below preheats the smoldering reactants that have not undergone smoldering reaction upwards, thereby increasing the stability of the smoldering reaction.

[0059] In addition, during ventilation, the fan 6 can diffuse the heat generated by the heater 5 upward into the smoldering reaction chamber 11, preheating the smoldering reactants that have not undergone smoldering reaction, and further increasing the stability of the smoldering reaction.
