Description

Technical Field

[0001] The invention relates to the technical field of boiler manufacturing, and in particular to a garbage power generation boiler. Background Art

[0002] At present, a large amount of hot air generated in the combustion chamber of the combustion power generation boiler will flow out at the feeding and ash discharge positions. When providing air to the combustion chamber for combustion assistance, the temperature difference between the cold air and the air in the combustion chamber consumes a certain amount of heat energy, making the combustion temperature and pressure in the combustion chamber unstable. In addition, the state in the combustion chamber cannot be clearly grasped and timely adjustments cannot be made, resulting in low combustion performance and high power generation costs. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a garbage power generation boiler which is convenient for unloading and observing the combustion state, and can also reduce energy consumption and improve combustion efficiency.

[0004] The technical solution of the present invention is as follows:

[0006] A bracket is provided on the outer wall of the combustion chamber, a stepper motor is provided on the upper end of the bracket, a through hole is provided on the bracket, a spherical support is provided in the through hole, a cooling water sleeve is detachably provided on the spherical support, a fixing hole is provided at one end of the cooling water sleeve, the fixing hole is sleeved and fixed with one end of a hollow heat dissipation shaft, the other end of the heat dissipation shaft passes through the cooling water sleeve and extends into the combustion chamber, a heat-resistant glass is provided at the hollow position of the end through which the heat dissipation shaft passes; a positioning flange is also provided on the cooling water sleeve, a mounting hole is provided on the positioning flange at a position corresponding to the heat dissipation shaft, an infrared thermal imaging camera is provided in the mounting hole, a transmission ball shaft is provided on the positioning flange, a wire hole connected to the mounting hole is provided in the transmission ball shaft, the wires of the infrared thermal imaging camera are electrically connected to the monitor via the wire hole, the outer side wall of the transmission ball shaft is sleeved with one end of a first connecting rod, a first transmission rod is inserted at the other end of the first connecting rod, and one end of the first transmission rod is connected to the output end of the stepper motor;

[0007] An air inlet and ash removal device is provided below the furnace bed, a slag removal device is provided at the discharge end of the furnace bed, and a slag removal and combustion-aiding device is provided on the ash discharge pipe. The air inlet and ash removal device includes an exhaust pipe connected to the ash hopper and a lower box body, the slag removal device includes a first air outlet pipe connected to the exhaust pipe, and the slag removal and combustion-aiding device includes a through hole provided on the receiving trough and connected to the lower box body. While effectively reducing the discharge of hot air, it is also convenient to preheat the input air and reduce the heat consumption in the combustion chamber.

[0008] With the above structure, the first unloading plate serves as a supporting plate for feeding, and the wheel surface of the first roller is in contact with the transition inclined wall. In this way, the first unloading plate isolates the interior of the boiler from the outside air. When the garbage feeding reaches a certain weight, the garbage pushes the first unloading plate to rotate counterclockwise, the first roller is separated from the transition inclined wall, and the garbage quickly falls onto the second unloading plate, and the wheel surface of the second roller is in contact with the inclined wall. The second unloading plate can also isolate the interior of the boiler from the outside air. Similarly, when the garbage feeding reaches a certain weight, it pushes the second unloading plate to quickly fall into the boiler. Then, under the action of the gravity of the first counterweight block, the first unloading plate quickly rotates clockwise, and the wheel surface of the first roller is in contact with the transition inclined wall again until the corresponding position of the elastic device moves When the second roller stops rotating, the first discharge plate stops rotating, and the boiler is restored to the state of isolation between the inside and the outside air. During this process, the garbage is automatically and orderly put in according to weight. As the weight of the garbage falls into the boiler, the load on the first discharge plate gradually decreases. That is, after the first discharge plate rotates to a certain displacement position, it begins to gradually rotate and move back, and gradually reduces the distance between the second roller and the transition inclined wall, instead of rotating and moving back after the garbage enters. This reduces the period and area of ​​contact between the outside air and the air inside the boiler. In addition, the isolation barrier formed by the depth of garbage accumulation during feeding and the small capacity of air heat exchange ensure the stability of the temperature and pressure in the boiler. The garbage dropped into the boiler enters the combustion chamber through the push of the push plate.

[0009] A bracket is arranged on the outer wall of the boiler at a position corresponding to the combustion chamber, a spherical bracket is arranged on the bracket, a cooling water shaft sleeve is arranged on the spherical bracket, a heat dissipation shaft extending into the combustion chamber is penetrated on the cooling water shaft sleeve, an infrared thermal imaging camera takes pictures of the combustion chamber through the hollow position of the heat dissipation shaft, and the infrared thermal imaging camera is arranged on a positioning flange connected to the transmission ball shaft, the output end of the stepper motor drives the first transmission rod and the first connecting rod to rotate, the transmission ball shaft sleeved on the first connecting rod makes an adaptive spherical rotation, and synchronously drives the spherical bracket to make an adaptive spherical rotation on the bracket, that is, drives the heat dissipation shaft to rotate with the spherical shaft. The support frame rotates synchronously with the rotation of the support frame. During the rotation process, the insertion positions of the first connecting rod and the first transmission rod will produce adaptive length changes with the rotation of the output end of the stepper motor, thereby increasing the range of the rotation angle, so as to achieve a certain wide-angle lens use effect and expand the range of the observation angle; the heat-resistant glass can prevent the ash from entering the heat dissipation shaft to avoid affecting the camera effect; the infrared thermal imaging camera can not only observe the combustion situation in the combustion chamber through video, but also distinguish the temperature distribution in the combustion chamber, and can timely adjust the combustion gas supply and related combustion parameters to improve the combustion efficiency and avoid the occurrence of insufficient combustion;

The air intake volume is increased and an automatic ash discharge device is set at the lower end of the ash hopper. It can not only prevent the outflow of air intake, but also ensure the timely discharge of ash under the premise of sufficient combustion; the slag removal device can not only preheat the intake temperature, but also assist in the evacuation of ash, thereby improving the utilization efficiency of the boiler; the slag removal and combustion-aiding device can also preheat the intake temperature, ensure the combustion temperature in the boiler combustion chamber, and maintain orderly slag removal, thereby improving the utilization efficiency of the boiler.

[0087] Depend on Figure 1 , Figure 22 to Figure 25 As shown, the slag removal and combustion-aiding device includes a material receiving trough 52 with an opening upward provided at the slag discharge position of the furnace bed, and a double helical shaft 53 is provided in the material receiving trough 52 along the axial direction.

Bolts are inserted from top to bottom through the connecting clearance hole and the connecting through hole, and the protruding end of the bolt is riveted by a nut so that the nut of the bolt presses the sealing sleeve tightly and fixes it on the partition.

[0090] The partitions are evenly arranged along the circumferential direction on the second rotating shaft 541 .

[0091] The method of use of the present invention is as follows:

[0092] like Figures 1 to 4 As shown, a second discharge plate 132 is additionally provided below the first discharge plate 131, and a cavity structure is enclosed between the two discharge plates and the feed hopper 1. When in use, the first discharge plate 131 serves as a support plate for feeding, the wheel surface of the first roller 151 is in contact with the transition inclined wall 112, and the wheel surface of the second roller 152 is in contact with the inclined wall 111. In this way, the first discharge plate 131 and the second discharge plate 132 realize double isolation of the inside of the boiler from the outside air. When the garbage feed reaches a certain weight, the garbage pushes the first discharge plate 131 to rotate counterclockwise (such as Figure 4The first roller 151 is separated from the transition inclined wall 112, and the garbage quickly falls into the cavity structure. Then, under the gravity of the first counterweight 141, the first discharge plate 131 quickly rotates in the clockwise direction, and the wheel surface of the first roller 151 is again in contact with the transition inclined wall 112, and the boss 154 abuts against the first guide sleeve 163, driving the first mounting sleeve 166 to squeeze the first compression spring 1531. When the first compression spring 1531 is squeezed to the limit position, the first roller 151 stops rotating, that is, the first discharge plate 131 stops moving, and the boiler is restored to the initial isolation state between the inside and the outside air (as shown in FIG. Figure 3 and Figure 4 In this process, the garbage is automatically and orderly put in according to its weight. As the weight of the garbage falls into the cavity structure, the load on the first discharge plate 131 gradually decreases, that is, after the first discharge plate 131 rotates to a certain displacement position, it begins to gradually rotate and move back, and gradually reduces the distance between the first roller 151 and the transition inclined wall 112, instead of rotating and moving back after all the garbage enters. This reduces the period and area of ​​contact between the outside air and the air inside the boiler. In addition, the depth of the garbage accumulation forms an isolation barrier during feeding, and the capacity of air heat exchange is small, which together ensures the stability of the temperature and pressure in the boiler.

[0093] At this time, the garbage is accumulated on the second unloading plate 132, and the outside air is only connected to the cavity structure. Then, the first unloading plate 131 rotates rapidly under the gravity of the first counterweight block 141. In this process, the weight of the garbage pushes the second unloading plate 132 to rotate in the counterclockwise direction (such as Figure 4 The second unloading plate 132 stops moving, and the first unloading plate 131 stops moving.

[0094] During the above-mentioned use, when the two unloading plates rotate to unload, in order to prevent the opening arc from being too large and prolonging the air connection period, the limit groove 1312 at the corresponding position is sleeved and abutted on the limit pin 1211, so as to ensure the unloading capacity and at the same time ensure that the rotation period of the unloading plate is consistent. Similarly, in order to prevent the roller from moving too much and causing the boiler seal to fail, the bending section position on the counterweight block is turned and abutted against the limit pin to ensure the fit between the roller surface and the two inclined walls; the sealing cover (14) ensures the sealing of the inspection hole position, and opening the sealing cover 14 is also convenient for inspection.

[0095] In summary, the two discharge plates are alternately opened and closed in the feed hopper 1, which can not only unload the garbage in an orderly manner, but also effectively ensure the relative sealing of the boiler combustion chamber, greatly reduce the entry of air, reduce the heat energy consumption required for air heat exchange, and improve combustion efficiency.

[0096] like Figures 5 to 9 As shown, a bracket 21 is arranged at a position corresponding to the combustion chamber on the outer wall of the boiler, a spherical shell 211 is arranged on the bracket 21, four fixed brackets 214 are arranged in the spherical shell 211, four connecting ears 215 are arranged correspondingly on the cooling water shaft sleeve 22, the four connecting ears 215 are screwed on the fixed brackets 214 at the corresponding positions, a heat dissipation shaft 221 extending into the combustion chamber is penetrated on the cooling water shaft sleeve 22, an infrared thermal imaging camera 24 screwed and fixed in the positioning flange 23 takes pictures of the combustion chamber through the hollow position of the heat dissipation shaft 221, and the positioning flange 23 is screwed and fixedly connected to the transmission ball shaft 25.

[0097] When in use, the output end of the stepper motor 26 drives the first transmission rod 253 and the first connecting rod 252 to rotate. At the same time, the transmission ball shaft 25 sleeved on the first connecting rod 252 makes an adaptive spherical rotation at the sleeved position, and synchronously drives the spherical shell 211 to make an adaptive spherical rotation on the bracket 21, which is similar to the use effect of a universal swivel, that is, drives the heat dissipation shaft 221 to rotate synchronously with the rotation of the spherical shell 211. During the rotation process, the distance between the first connecting rod 252 and the first transmission rod 253 at the inserted position will produce an adaptive length change with the rotation of the output end of the stepper motor, and the connecting guide rod will adaptively reciprocate in the connecting guide hole, thereby increasing the range of the rotation angle, so as to achieve a certain wide-angle lens use effect and expand the range of the observation angle (such as Figure 8 and Fig. 9 The captured image data is transmitted to a monitor (not shown) by a data line passing through the wire hole 251 and displayed on the display screen of the monitor, which can not only detect faults but also serve as a high temperature warning, greatly improving production efficiency and production safety.

[0098] The heat-resistant glass provided can prevent furnace ash from entering the heat dissipation shaft 221 to avoid affecting the camera effect; the infrared thermal imaging camera 24 can not only observe the combustion conditions in the combustion chamber by video, but also distinguish the temperature distribution in the combustion chamber, and can timely adjust the combustion air supply and related combustion parameters to improve combustion efficiency and avoid incomplete combustion. It has a simple and compact structure and is easy to use.

[0099] It should be noted that the magnesium aluminum silicate sleeve 2212 used in this embodiment is embedded in the clearance hole and is sleeved on the outer wall of the cooling water shaft sleeve 22 (such as Figure 6 As shown), since magnesium aluminum silicate is a material with a very developed internal microporous system, in addition to being resistant to high temperatures, it has a strong deformation ability. During the rotation of the cooling water sleeve 22, it can not only be well sleeved on the outer wall of the cooling water sleeve 22, but also can realize pressure-yielding deformation in the clearance hole, which can not only realize the sealing effect in the clearance hole, but also avoid the rotation interference of the cooling water sleeve 22.

[0100] like Figures 10 to 17 As shown, the moving row and the fixed row in the furnace are arranged obliquely to facilitate ash discharge, wherein the fixed row and the moving row are arranged at intervals, the fixed row is fixed, and the moving row is moved back and forth in an oblique direction by a transmission device, so that the raw materials are fully burned and the burned ash is turned over and piled out of the furnace in sequence; in this process, six cavity structures are formed in each air distribution sleeve by the corresponding positions of the fan blades 323 and the inner wall of the shell 327, forming six air circulation branches, each of which is connected to the curved injection pipe 325 at the corresponding position through the connecting hole 324, and under the guidance of the curved pipeline of the curved injection pipe 325 , a spiral air flow is formed in the ash hopper 311 and circulates upward. Since the wind path is divided into multiple parts, multiple spiral air flows converge upward to form a strong penetrating wind pressure, which enhances the penetrating power of the air supply and is more conducive to the incoming air to blow away the ash accumulated in the gap between two adjacent moving row blocks, thereby quickly transporting it to the combustion chamber above the furnace bed, ensuring the incoming air volume and sufficient combustion of the garbage; at the same time, part of the cyclone formed is reflected on the inner wall of the ash hopper 311 to form a wind force blowing vertically downward, which is more conducive to pushing the remaining ash on the inner wall of the ash hopper 311 to the ash storage cylinder 331 at the lower end of the ash hopper 311, so as to facilitate the collection and discharge of ash.

[0101] At the same time, an ultrasonic positioning probe 343 is arranged at the lower end of the ash hopper 311, and detection parameters are set on the PLC controller. The height value of the ash accumulation in the upper box body 341 is detected to send a signal to the PLC, and the PLC controller starts the servo motor 35 in a timely manner to drive the ash accumulation barrel 331 to rotate. Before the rotation, the feed port 3311 is connected with the upper box body 341, and the discharge port 3312 faces the lower left side of the inner wall of the lower box body 342 and is separated from the lower box body 342. At this time, the ash accumulation barrel 331, the upper box body 341 and the ash hopper 311 are connected, and are not connected with the lower box body 342. After the second transmission rod 351 drives the second connecting rod 336 to rotate counterclockwise ( Fig.15 The feed port 3311 is toward the upper left side of the inner wall of the upper box body 341 and is separated from the upper box body 341, and the discharge port 3312 is connected to the lower box body 342. At this time, the upper box body 341 is connected to the ash hopper 311, but not to the lower box body 342. After the ash storage cylinder 331 has discharged all the ash, the servo motor 35 rotates, and the feed port 3311 is connected to the upper box body 341, and the discharge port 3312 is separated from the lower box body 342. There will be a period of connection between the feed port 3311 and the discharge port 3312 when they are turned over. This period of time can be controlled by setting the rotation speed of the servo motor 35 to ensure that not too much air is discharged from the ash hopper 311, thereby ensuring the stability of the air supply.

[0102] During use, if Fig.15 As shown, eight grooves are symmetrically arranged on the outer wall of the ash accumulation barrel 331, and a graphite lubricating plate 332 is arranged in each groove to ensure the consistency of the rotational lubrication state and prevent the ash accumulation barrel 331 from forming a cam rotation state, so as to avoid the insufficient communication area between the discharge port 3312 and the lower box body 342, thereby blocking the ash discharge and affecting the ash discharge efficiency; grooves are arranged at the discharge end of the upper box body 341 and the feed end of the lower box body 342, and lubricating blocks 344 are embedded in the grooves. Fig.15 and 16 It can be seen that the lubricating block 344 is in contact with the outer wall of the ash storage cylinder 331, and the air in the ash hopper 311 can only flow out through the ash storage cylinder 331. Therefore, when the discharge port 3312 is not transferred to the feeding end of the lower box body 342, the ash storage cylinder is always in a partition state with the lower box body 342, and no air will flow out. Fig.16 As shown, the steel ball 335 and the outer wall of the ash storage cylinder 31 are both arc surfaces, and three pressure blocks 333 are respectively provided at the position corresponding to each graphite lubricating plate 332 along the circumferential direction on the support seat 33. As the graphite lubricating plate 332 wears, the pressure blocks 333 are always squeezed by the elastic force of the second compression spring 334 to roll and abut against the outer wall of the ash storage cylinder 331. The symmetrical force on the left and right reduces the rotational resistance, thereby ensuring the smooth rotation of the ash storage cylinder 331. In order to maintain a consistent lubrication state, the lubricating blocks 344 are also made of graphite material.

[0103] There is an angle of 135° between the feed port 3311 and the discharge port 3312. After the ash storage cylinder 331 is rotated into place, the ash hopper 311 is not connected to the outside world, which effectively prevents the outflow of intake air and ensures sufficient combustion air supply.

[0104] like Figure 18 to Figure 21 As shown, a ratchet sleeve 44 is provided on the first rotating shaft 42, and the ash removed by the moving row group 41 is moved to the ratchet sleeve 44 and retained in the tooth grooves of the ratchet sleeve 44 in batches. The temperature of the ash is transferred to the ratchet sleeve 44 and the heat is transferred to the air input by the first intake pipe 431 through the first rotating shaft 42, and the waste heat of the ash is used to increase the intake temperature of the combustion chamber. The preheated air flows into the exhaust pipe 32 through the first outlet pipe 432 and enters the combustion chamber, so that the heat loss in the boiler is reduced and the stability of the combustion temperature can be ensured.

[0105] During this process, the transition plate 421 and the transition grate 422 block the gap between the moving row group 41 and the first rotating shaft 42, and can assist in the discharge of ash. The hinged transition grate 422 overlaps the outer wall of the ratchet sleeve 44. As the ratchet sleeve 44 rotates, the non-hinged end of the transition grate 422 swings in the upward and downward directions with the rotation of the ratchet sleeve 44, that is, when the ratchet sleeve 44 rotates, the arc surface 4223 swings along the shape of the groove position of the tooth groove and the tooth top position, which helps to shake off the ash so that it can be fully burned and avoid accumulation into blocks, which is beneficial to the discharge of ash. At the same time, since the ratchet pressure plate 442 is screwed in the tooth groove, the depth of the tooth groove becomes shallower, which not only reduces the accumulation of ash, but also facilitates disassembly and cleaning. In addition, the conical surface of the ash guide cone 441 also guides the ash to gather towards the middle of the ratchet sleeve 44 during movement to prevent the ash from leaking out.

[0106] Since the transition plate 421 is also hinged on the first bracket 411, and the hinged end of the transition grate 422 is located at the notch position of the transition plate 421, and the upper end wall at the notch position overlaps the upper end surface of the straight section 4221, thereby, in addition to preventing the ash from leaking out, the swinging of the transition grate 422 also drives the transition plate 421 which is hinged on the second bracket 412 to also produce a small range of displacement, and the transition plate 421 forms a rhythmic angle change at the overlapping position with the moving row group 41. When the angle is large, that is, the transition plate 421 is at the position of the maximum displacement when it swings counterclockwise, the transition plate 421 forms a scraping effect on the upper end surface of the moving row group 41. As the swinging continues, an intermittent scraping action is formed, which can prevent the ash on the moving row group 41 from sticking and accumulating, and improve the efficiency of discharging the ash. The structure is simple and compact, and the use effect is good.

[0107] Depend on Figure 22 to Figure 25As shown, a double helix shaft 53 with a hollow structure is arranged in the receiving trough 52, and the ash in the combustion chamber falls into the receiving trough 52 through the dynamic row group 41, and the ash in the ash hopper 311 also falls and moves into the receiving trough 52 through the ash main pipe (not shown) and the through hole 521. The temperature of the ash is transferred to the double helix shaft 53, and the heat is transferred to the air input by the second air inlet pipe 531 through the double helix shaft. The air preheated by the waste heat of the ash is discharged into the exhaust pipe 32 through the second air outlet pipe 532 and enters the combustion chamber 2. On the one hand, the intake temperature of the combustion chamber is increased and the heat loss in the incinerator is reduced. On the other hand, the stability of the combustion temperature can be guaranteed.

[0108] At the same time, the starting motor drives the double spiral shaft 53 to rotate, and the spiral blades are used to concentrate the furnace ash at both ends of the receiving trough 52 to the middle of the receiving trough 52, and fall into the box body 54 through the ash outlet 522. A second rotating shaft 541 with a partition is provided in the box body 4, and two first partitions 551, two second partitions 552 and two third partitions 553 are symmetrically provided on the second rotating shaft 541. The six partitions are evenly arranged along the circumferential direction, and each partition is provided with a sealing sleeve. The specific working principle is:

[0109] A cavity groove structure is formed between two adjacent partitions and the second rotating shaft 541. At this time, the furnace ash falls into the three cavity grooves in the upper part of the box body 54, and the sealing sleeves 56 on the two second partitions 552 are in contact with the outer wall of the sealing ring 561, and the combustion chamber and the discharge port at the lower end of the box body 54 are in a partitioned state; when the second rotating shaft 541 continues to rotate counterclockwise, the sealing sleeves 56 on the two first partitions 551 and the second partition 552 are in contact with the sealing ring 561, and the furnace ash only falls into the two cavity grooves in the upper part of the box body 54, and the combustion chamber and the discharge port at the lower end of the box body 54 are still in a partitioned state (such as Fig.25 As shown in Figure e); the second rotating shaft 541 continues to rotate counterclockwise, at this time, the sealing sleeve 56 on the second partition plate 552 leaves the position of the sealing ring 561, and a gap is exposed in the cavity groove at the lower left of the box body 54, and the ash inside it begins to be discharged outside the discharge port, while the ash falling from the ash outlet 522 still falls into the two cavity grooves at the upper part of the box body 54, and the sealing sleeves 56 on the third partition plate 553 and the first partition plate 551 are both in contact with the sealing ring 561, and the combustion chamber is still in a partitioned state with the outside world (as shown in Figure e); the second rotating shaft 541 continues to rotate counterclockwise, at this time, the sealing sleeve 56 on the second partition plate 552 leaves the position of the sealing ring 561, and the cavity groove at the lower left of the box body 54 reveals a gap, and the ash inside begins to be discharged outside the discharge port, and the ash falling from the ash outlet 522 still falls into the two cavity grooves at the upper part of the box body 54, and the sealing sleeves 56 on the third partition plate 553 and the first partition plate 551 are both in contact with the sealing ring 561, and the combustion chamber is still in a partitioned state with the outside world (as shown in Figure e); the second rotating shaft 541 continues to rotate counterclockwise, at this time, the sealing sleeve 56 on the second partition plate 552 leaves the position of ... Fig.25 As shown in Figure f in the figure), the second rotating shaft 541 rotates continuously in this way, which can not only discharge the ash in batches, but also ensure that the combustion chamber 2 is always isolated from the outside world, that is, further ensure the stability of the combustion temperature in the combustion chamber 2 and improve the utilization efficiency.

[0110] It should be noted that a plurality of ash hoppers 311 are provided under the furnace bed, so a plurality of through holes 521 are provided in the receiving trough 52 to communicate with the ash hoppers 311 at corresponding positions. The number of through holes 521 shown in the figure is not unique and should be adapted to the specific boiler specifications; the sealing ring 561 is made of copper-impregnated graphite, which can not only reduce the rotational wear of the sealing sleeve 56, but also ensure the better rotational smoothness of the sealing sleeve 56; the number of partitions should be set according to the span of the feed port and the discharge port of the box body 54 to meet the use requirements. This embodiment is not unique.

[0111] In addition, the upper end of the combustion chamber 2 is connected to a smoke chamber (omitted and not marked here). In order to facilitate adjustment of the position of the motor-driven double screw shaft 53, it is appropriate to adopt a pulley drive and adaptable installation. The parts not described in the present invention are consistent with the prior art and will not be repeated here.
