Description

Technical Field

[0001] The present invention relates to the technical field related to incinerator equipment, and in particular to an explosion-proof incinerator. Background Art

[0002] Explosion-proof incinerators are critical equipment for treating flammable and explosive hazardous wastes, such as organic solvent waste, dust-laden exhaust gases, and specific chemical residues. They are widely used in the chemical, pharmaceutical, petroleum, military, and environmental protection sectors. In certain high-risk processes or when treating waste with complex and volatile composition, there is a risk of frequent localized or transient explosions within the furnace. In these high-frequency explosion risk scenarios, ensuring the safety of the incinerator equipment and operators and preventing catastrophic accidents places high demands on the responsiveness, reliability, and sustainability of explosion-proof measures.

[0003] Currently, the mainstream explosion-proofing method generally utilizes passive explosion-proofing technology using a rupture disc (bursting disc). Its core operating principle is to install a vent at a specific location (such as the top or sidewall) within the furnace (usually the combustion chamber or flue). This vent is sealed by a rupture disc with a preset burst pressure. When an unexpected explosion occurs within the furnace, the combustion gases expand rapidly, causing a sudden increase in pressure within the furnace. Once the pressure exceeds the rated burst pressure threshold of the vent disc, the disc ruptures within a very short time (on the order of milliseconds). The vent then opens, connecting the furnace to a vent box (pressure relief chamber) or a safe relief duct. The volume of the vent box or duct is much greater than the volume of the airflow released instantly by the vent, effectively increasing the effective space for containing the explosion products. This rapidly releases the overpressure, reducing the furnace pressure to below a safe level and preventing damage to the furnace structure.

[0004] However, the above explosion-proof solution based on explosion-proof membrane has defects:

[0005] Explosion venting membranes are typically designed for single use. Once ruptured during an explosion, they become permanently ineffective and must be manually replaced before the incinerator can resume operation. In applications where explosions are frequent, these disposable venting membranes require frequent replacement.

[0006] This raises the following questions:

[0007] First, the cost of consumables is high: frequent replacement of high-quality explosion-proof diaphragms results in continuous material expenditure;

[0008] Second, maintenance is labor-intensive and dangerous: replacement operations require a series of steps, including shutdown, cooling, disassembly, installation, and sealing testing, which consumes a lot of manpower and time, and exposes operators to potentially dangerous environments.

[0009] Third, the downtime losses are serious: each replacement means that the incinerator stops processing waste, affecting the overall production process.

[0010] Therefore, the existing explosion-proof membrane technology is difficult to adapt to the urgent demand for sustainable, maintenance-free or low-maintenance operation of explosion-proof devices in high-frequency explosion scenarios. A reusable and reliable explosion-proof technology that does not require frequent replacement is urgently needed to solve the above problems. Summary of the Invention

[0011] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a reusable explosion-proof incinerator that does not require frequent replacement of explosion-proof devices, thereby meeting the demand for sustainable, maintenance-free or low-maintenance operation of explosion-proof devices in high-frequency explosion scenarios.

[0012] An explosion-proof incinerator proposed in the present invention comprises a furnace body and a feeding mechanism and a smoke exhaust mechanism respectively located on both sides of the furnace body, and a feeding and smoke exhaust port is provided at the upper end of the furnace body.

[0013] The difference from the traditional structure is that the smoke exhaust mechanism includes a smoke exhaust base shell, one end of which is open for docking with the feed smoke exhaust port, the side of the smoke exhaust base shell is connected to the smoke exhaust pipe, a slide box is provided in the smoke exhaust base shell, and a smoke exhaust passage is formed in the slide box. One end of the smoke exhaust passage extends to the outside of the slide box to correspond to the feed smoke exhaust port, and the other end of the smoke exhaust passage extends to the outside of the slide box to correspond to the side of the smoke exhaust base shell;

[0014] When the sliding box is displaced to its side corresponding to the smoke exhaust pipe, the smoke is discharged through the smoke exhaust passage and the smoke exhaust pipe; when the sliding box is displaced to its side and staggered with the smoke exhaust pipe, one end of the smoke exhaust passage is closed, and the smoke is discharged through the smoke exhaust base shell and the smoke exhaust pipe.

[0015] The advantages of this arrangement are: the use of a sliding explosion vent (sliding box) combined with an integrated smoke exhaust structure realizes a retriggered active explosion venting mechanism, fundamentally solving the problem of frequent replacement caused by the one-time use of traditional explosion venting membranes;

[0016] Specifically, when the incinerator is operating normally, the slide box is in the closed position of the smoke exhaust duct, the smoke exhaust passage is precisely connected to the feed smoke exhaust port, and the smoke gas forms a directional smoke exhaust channel through the smoke exhaust passage and the smoke exhaust duct. At this time, the smoke is efficiently introduced into the smoke exhaust duct through the smoke exhaust passage inside the slide box, and the system maintains a constant smoke exhaust cross-sectional area to ensure that the incineration efficiency is not affected. In addition, the area inside the smoke exhaust base shell that accommodates the slide box is pre-set with the expansion space required for explosion venting, providing a physical basis for explosion response.

[0017] When the explosion is triggered, the overpressure gas impacts the end face of the slide box, pushing it to displace axially along the smoke exhaust base shell until the side wall of the slide box is misaligned with the entrance of the smoke exhaust pipe, causing the dual explosion relief paths to be activated simultaneously: first, after the slide box is displaced, its original occupied space is instantaneously released in the smoke exhaust base shell, forming an additional gas holding cavity, which directly absorbs the explosion shock wave and suppresses the pressure peak; second, the entrance of the smoke exhaust pipe is changed from the closed state of the slide box to the full cross-section exposure, and the discharge area is instantly expanded to the cross-sectional area of ​​the pipe, which is much larger than the original cross-sectional area of ​​the smoke exhaust passage. The smoke and overpressure gas are turbulently discharged through this channel, achieving millisecond-level pressure unloading.

[0018] This solves the defects of the prior art, such as high consumables cost, heavy maintenance workload and downtime losses.

[0019] In some examples of the present invention, the smoke exhaust passage is composed of a plurality of pipes, including an annular pipe and a plurality of longitudinal pipes, one end of the plurality of longitudinal pipes extends outside the slide box to correspond to the feed smoke exhaust port, and the other end extends to communicate with the annular pipe, and an end of the annular pipe close to the smoke exhaust pipe is open and connected to the docking pipe, and the docking pipe extends outside the slide box.

[0020] The purpose of this setting is to radially divert and collect the flue gas at the furnace outlet through multiple longitudinal pipes, thereby eliminating the flue gas deviation caused by the deviation of the flue gas position; at the same time, the annular pipe is used as a pressure-stabilizing chamber to integrate the discrete airflow into axial laminar flow, thereby avoiding the vortex generated by the airflow collision; in addition, the design of the smoke exhaust passage can also provide a coherent mechanical guide reference for the displacement of the slide box, thereby preventing the sealing failure caused by the misalignment of the pipe.

[0021] In some examples of the present invention, an elastic member is further provided in the smoke exhaust base shell, and the elastic member is located at an end of the slide box away from the opening of the smoke exhaust base shell.

[0022] The purpose of this setting is: on the one hand, the compressive force of the explosion pushes the slide box to compress the elastic part, converting most of the impact kinetic energy into elastic potential energy storage, significantly reducing the dynamic load transmitted to the smoke exhaust base shell, and the elastic part forms a delayed buffer during the compression operation to avoid pressure peaks damaging the smoke exhaust casing; on the other hand, after the pressure is released, the elastic part releases the stored energy, pushing the slide box to reset, and the smoke continues to be introduced into the smoke exhaust pipe through the smoke exhaust passage inside the slide box, and the incinerator maintains normal operation.

[0023] In some examples of the present invention, the elastic member is a pagoda spring.

[0024] The purpose of this setting is: on the one hand, the pagoda spring adopts a gradient design to match the explosion curve; on the other hand, the compression of the pagoda spring is relatively large, which can maximize the buffering stroke within the limited smoke exhaust base shell.

[0025] In some examples of the present invention, a limiting protrusion is provided on one end of the sliding box close to the elastic member, and the limiting protrusion is used to limit the elastic member.

[0026] The purpose of such arrangement is to prevent the elastic member from deviating from the expected extension and contraction direction during operation.

[0027] In some examples of the present invention, a guide column is further provided in the smoke exhaust base shell, and a conduit is formed in the slide box. One end of the guide column extends to be slidably connected to the smoke exhaust base shell, and the other end extends into the conduit and is fixedly connected to the slide box.

[0028] The purpose of such setting is that the core function of the guide column is to resist the radial deviation of the slide box caused by the explosion impact.

[0029] In some examples of the present invention, one end of the guide column away from the slide box extends to the outside of the smoke exhaust base shell, a plurality of teeth are provided in the middle of the guide column, and the plurality of teeth extend along the axial direction of the guide column. A gear roller that can engage with the teeth is provided at the upper end of the smoke exhaust base shell, and the gear roller is rotatably arranged relative to the smoke exhaust base shell, and one end thereof is connected to the encoder.

[0030] The purpose of this setting is to use the guide column to transmit the displacement movement of the slide box to the outside of the smoke exhaust base shell, and convert the linear displacement into angular displacement through the gear roller. The encoder captures the angular displacement, tracks the explosion displacement of the slide box in real time, realizes the explosion equivalent evaluation, and records data for the incinerator explosion event, thereby preparing for more precise control and digital control; this explosion event detection method uses the kinetic energy of the explosion to drive the gear rotation, without the need for the deployment of a corresponding electronic control system, and meets the mandatory safety standards for non-electric monitoring in explosion-proof areas.

[0031] In some examples of the present invention, a gear roller shell is provided on the upper end of the smoke exhaust base shell, both ends of the gear roller are connected to the gear roller shell through bearings, and one end extends outside the gear roller shell.

[0032] The purpose of this setting is to install the gear roller outside the smoke exhaust base shell, and the gear roller is enclosed by the gear roller shell. The double-layer shell (smoke exhaust base shell and slide box) forms a thermal isolation buffer zone, forming an effective thermal barrier for the gear assembly inside the gear roller shell, isolating the gear system from the erosion of smoke and dust exceeding 600°C.

[0033] In some examples of the present invention, the smoke exhaust mechanism is installed on the first frame, the first frame is slidably arranged on the first slide rail through the first pulley, and the first frame is connected to the first fixing pile through the first telescopic rod.

[0034] In some examples of the present invention, the feeding mechanism is installed on the second frame, the second frame is slidably arranged on the second slide rail through a second pulley, and the second frame is connected to the second fixed pile through a second telescopic rod.

[0035] The purpose of such arrangement is that the feeding operation and smoke exhaust operation of the furnace body are both carried out at the feeding and smoke exhaust port, that is, the feeding and smoke exhaust share an opening, so the smoke exhaust mechanism is installed on the first frame so that the first frame is movable, and the feeding mechanism is installed on the second frame so that the second frame is movable, so that the feeding mechanism and the smoke exhaust mechanism can operate at staggered times.

[0052] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components.

[0053] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0054] Reference below Figures 1 to 6 The figure shows an explosion-proof incinerator provided by an embodiment of the present invention.

[0055] For details, please see the attached Figure 1 ~Attached Figure 2 , attached Figure 1 This is a schematic diagram of an explosion-proof incinerator in the charging state. Figure 2 This is a schematic diagram of an explosion-proof incinerator in the incineration and smoke exhaust state. The incinerator comprises a furnace body 1 and a feeding mechanism 2 and a smoke exhaust mechanism 3 located on either side of the furnace body 1. A feeding and smoke exhaust port 11 is provided at the upper end of the furnace body 1, i.e., both feeding and smoke exhaust operations are carried out through the feeding and smoke exhaust port 11. The furnace body 1 is erected and vacated, and a discharge port 12 is provided at its lower end. After the incineration operation is completed, the slag can be discharged through the discharge port 12 and discharged from the surrounding Figure 1 It can be seen that the feeding mechanism 2 corresponds to the feeding smoke outlet 11, and the smoke exhaust mechanism 3 is located on one side of the furnace body 1. At this time, the furnace body 1 can be fed. Figure 2 It can be seen that the smoke exhaust mechanism 3 corresponds to the feed smoke exhaust port 11, and the feed mechanism 2 is located on one side of the furnace body 1. At this time, the furnace body 1 can perform incineration and smoke exhaust operations.

[0056] Please see the attached Figure 3 ~Attached Figure 4 , attached Figure 3 It is a top view of the smoke exhaust mechanism 3, Figure 4 For attachment Figure 3 In the cross-sectional view at AA, the smoke exhaust mechanism 3 includes a smoke exhaust base shell 31, which is cylindrical and has an opening at one end for docking with the feed smoke exhaust port 11. The smoke exhaust base shell 31 can be mechanically sealed with the feed smoke exhaust port 11 by means of a snap. A side opening 311 is opened on the side of the smoke exhaust base shell 31, and the side opening 311 is connected to the feed smoke exhaust port 11. Figure 2The exhaust pipe 32 is connected to the exhaust base shell 31, and a slide box 33 is provided in the exhaust base shell 31. A smoke exhaust passage 34 is formed in the slide box 33. One end of the exhaust passage 34 extends to the outside of the slide box 33 to correspond to the feed exhaust port 11, that is, this end of the exhaust passage 34 extends to the open end of the exhaust base shell 31, and the other end of the exhaust passage 34 extends to the outside of the slide box 33, that is, extends to correspond to the side opening 311;

[0057] Thus, when the incinerator is in a normal burning state, the slide box 33 closes the side opening 311, leaving only the smoke exhaust passage 34 connected to the smoke exhaust pipe 32. At this time, the smoke is discharged through the smoke exhaust passage 34 and the smoke exhaust pipe 32, and the smoke exhaust volume of the smoke exhaust passage 34 matches the smoke exhaust volume of normal incineration.

[0058] When an explosion occurs in the incinerator, the pressure generated by the instantaneous explosion acts on the slide box 33, causing the slide box 33 to produce a linear displacement along the axial direction of the smoke exhaust base shell 31, as shown in FIG. Figure 5 As shown (attached Figure 5 For attachment Figure 4 Schematic diagram of the smoke exhaust mechanism 3 in the explosion state), the space originally occupied by the slide box 33 is instantly released, and after the slide box 33 is displaced, one end of the smoke exhaust passage 34 is closed, the side opening 311 is exposed, and the space of the smoke exhaust duct 32 is also released, realizing instantaneous explosion relief. This explosion relief method is not destructive explosion relief, and realizes a retriggerable active explosion relief mechanism.

[0059] Please continue to see the attached Figure 4 A stopper 312 is provided at the open lower end of the smoke exhaust base shell 31 . The stopper 312 is formed on the inner edge side of the smoke exhaust base shell 31 . Its function is to limit the sliding box 33 to prevent the sliding box 33 from separating from the smoke exhaust base shell 31 .

[0060] Please continue to see the attached Figure 4 The slide box 33 is also cylindrical as a whole, and relative displacement can occur between its outer wall and the inner wall of the smoke exhaust base shell 31. Therefore, a bearing 35 is installed between the two. The bearing 35 is specifically fixedly installed on the inner wall of the smoke exhaust base shell 31 to assist the relative displacement between the two, and high-temperature lubricating grease is passed between the bearing 35 and the outer wall of the slide box 33. The high-temperature lubricating grease is used to assist relative displacement on the one hand and to achieve sealing on the other.

[0061] Please continue to see the attached Figure 4The sliding box 33 includes a box body 331 and an end cover 332. The upper end of the box body 331 is open, the lower end is closed, and a cylindrical member 3311 is formed in the middle along the axial direction. The lower end of the cylindrical member 3311 is integrally formed with the box body 331, and the upper end is a free end. The existence of the cylindrical member 3311 makes the cavity in the box body 331 an annular cavity 3312. The end cover 332 is an annular end cover, which is installed at the open end of the box body 331 to close the annular cavity 3312 and is locked to the box body 331 by a first screw 333.

[0062] The sliding box 33 is set to be split, mainly to facilitate the installation of the smoke exhaust passage 34 in the sliding box 33;

[0063] For details, please refer to the attached Figure 4 The smoke exhaust passage 34 is composed of a number of pipes, including an annular pipe 341 and a number of longitudinal pipes 342. The number of longitudinal pipes 342 is evenly distributed along the annular cavity 3312 of the slide box 33. One end of each longitudinal pipe 342 extends to the outside of the slide box 33 to correspond to the feed smoke exhaust port 11, and is welded to the slide box 33, and the other end extends to communicate with the annular pipe 341. An open end of the annular pipe 341 close to the smoke exhaust pipe 32 is formed and connected to the docking pipe 343. The docking pipe 343 extends to the outside of the slide box 33. When the incinerator is in a normal incineration state, the end of the docking pipe 343 extending to the outside of the slide box 33 is communicated with the smoke exhaust pipe 32.

[0064] Please continue to see the attached Figure 4 The wall thickness of the longitudinal pipe 342 is designed to increase gradually. Specifically, the wall thickness of the inlet end is greater than that of the outlet end, forming a three-dimensional truss structure, which further improves the overall seismic strength of the slide box 33; the annular pipe 341 can serve as an instantaneous pressure buffer chamber when an explosion occurs, dispersing the instantaneous dynamic pressure exerted on the slide box 33, that is, converting the smoke exhaust passage 34 into a pressure-bearing skeleton, thereby improving the overall explosion-proof pressure of the slide box 33; in addition, each longitudinal pipe 342 is connected to the annular pipe 341 with a floating flange 344, which allows a slight axial thermal expansion displacement to avoid the accumulation of high-temperature welding stress.

[0065] Please continue to see the attached Figure 4 , an elastic member 36 is further provided in the smoke exhaust base shell 31, the elastic member 36 is located at one end of the slide box 33 away from the open end of the smoke exhaust base shell 31, and the elastic member 36 is a pagoda spring;

[0066] Specifically, the pagoda spring is a truncated cone spiral structure with a gradient design. The end close to the slide box 33 adopts a dense ring design, and the end away from the slide box 33 adopts a sparse ring design. In the high-pressure stage of the explosion, the sparse ring part is used to limit the displacement overshoot, and in the high-pressure stage, the dense ring part is used to ensure sensitive response.

[0067] Please continue to see the attached Figure 4A limiting protrusion 3321 is provided on one end of the sliding box 33 close to the elastic member 36, and the limiting protrusion 3321 is used to limit the elastic member 36; specifically, the limiting protrusion 3321 is a protruding annular protrusion formed on the end cover 332, and the pagoda spring is placed on the inner ring of the annular protrusion.

[0068] Please continue to see the attached Figure 4 A guide column 37 is further provided in the smoke exhaust base shell 31, and a conduit 3313 is formed in the slide box 33. One end of the guide column 37 extends to be slidably connected to the smoke exhaust base shell 31, and the other end extends into the conduit 3313 and is fixedly connected to the slide box 33;

[0069] Specifically, the conduit 3313 is a cylindrical pipe formed on the cylindrical member 3311 of the box body 331 and is coaxial with the slide box 33. Both ends of the conduit 3313 extend to penetrate the cylindrical member 3311, and at the end away from the elastic member 36, the diameter of the cylindrical pipe increases, so that the cross-section of the conduit 3313 forms a T-shaped structure. Correspondingly, the guide column 37 includes a lower column section 371, which is adapted to the conduit 3313 and also has a T-shaped cross-section.

[0070] Please continue to see the attached Figure 4 The guide column 37 also includes an upper column section 372, which extends to penetrate the smoke exhaust base shell 31 and is slidably connected to the smoke exhaust base shell 31 through a high-precision linear bearing 38 to form a rigid motion pair, thereby achieving the guiding operation of the slide box 33.

[0071] Please continue to see the attached Figure 4 The guide column 37 further includes a heat-insulating column section 373 located between the lower column section 371 and the upper column section 372. The heat-insulating column section 373 is made of a ceramic coating material to prevent high temperature from being transferred to the upper portion of the smoke exhaust mechanism 3 through the guide column 37.

[0072] Specifically, the lower column section 371 forms a contraction tendency near one end of the thermal insulation column section 373, and the upper column section 372 forms a diffusion tendency near one end of the thermal insulation column section 373, so that the lower column section 371 and the upper column section 372 are respectively close to one end of the thermal insulation column section 373 to form a conical section with the thermal insulation column section 373, and a pressing plate 374 is provided so that the pressing plate 374 is sleeved on the guide column 37, and the inner wall surface of the pressing plate 374 covers the conical section, and the second screw 375 passes through the pressing plate 374, the end cover 332, and the columnar member 3311 in sequence to connect the lower column section 371, the upper column section 372, and the thermal insulation column section 373, and realize the fixed connection between the guide column 37 and the slide box 33.

[0073] Please continue to see the attached Figure 3 ~Attached Figure 6 , attached Figure 6 For attachment Figure 1In the cross-sectional view at BB, one end of the guide column 37 away from the slide box 33 extends to the outside of the smoke exhaust base shell 31, that is, the upper column section 372 extends to the outside of the smoke exhaust base shell 31 and is connected to the recording mechanism 39. Specifically, a plurality of teeth 3721 are formed in the middle of the upper column section 372, and the plurality of teeth 3721 extend along the axial direction of the guide column 37. The recording mechanism 39 includes a gear roller 391 arranged at the upper end of the smoke exhaust base shell 31 and engageable with the teeth 3721. The gear roller 391 is rotatably arranged relative to the smoke exhaust base shell 31, and one end thereof is connected to the encoder 392; the encoder 392 can obtain the number of rotations of the gear roller 391, thereby obtaining the displacement distance of the guide column 37, and further obtaining the explosion data of each time in the incinerator.

[0074] Please continue to see the attached Figure 4 ~Attached Figure 6 The upper end of the smoke exhaust base shell 31 is fixedly connected to a gear roller shell 393. Both ends of the gear roller 391 are connected to the gear roller shell 393 through bearings 394, and one end extends to the outside of the gear roller shell 393. The bearing 394 is used to assist the rotation of the gear roller 391. The end of the gear roller 391 extending outside the gear roller shell 393 is used to connect to the encoder 392.

[0075] Please continue to see the attached Figure 4 The lower end of the sliding box 33 is also connected to the ceramic filter plate 310 through a third screw 3101. The ceramic filter plate 310 is used to filter dust in the flue gas.

[0076] Specifically, in order to further insulate, avoid high temperature erosion of the gear system, and eliminate gear meshing failure caused by thermal deformation, the gear roller shell 393 is composed of an outer carbon steel explosion-proof layer and an inner ceramic fiber insulation layer.

[0077] Please continue to see the attached Figure 1 ~Attached Figure 2 The smoke exhaust mechanism 3 is installed on the smoke exhaust mechanism bracket 4, and the smoke exhaust mechanism bracket 4 includes a first frame 41. The first frame 41 is slidably arranged on the first slide rail 43 through a first pulley 42. The first frame 41 is connected to the first fixed pile 45 through a first telescopic rod 44. The first telescopic rod 44 is specifically a cylinder; when the incinerator is performing incineration operation, the first telescopic rod 44 drives the first frame 41 to extend, so that the smoke exhaust mechanism 3 is exactly corresponding to the feed and smoke exhaust port 11 of the furnace body 1.

[0078] Please continue to see the attached Figure 1 ~Attached Figure 2The feeding mechanism 2 includes a feeding hopper 21 and a screw conveyor 22 installed at the output end of the feeding hopper 21.
