Description

Technical Field

[0001] This invention relates to the field of incineration boiler technology, and more specifically, to a power plant incineration boiler with high thermal energy utilization efficiency. Background Technology

[0002] Biomass incineration boilers in power plants are key equipment for efficiently converting biomass energy into heat energy. Their core function is to feed biomass waste into the furnace and release heat energy through a controlled incineration process. The equipment uses the high-temperature flue gas generated by the combustion of biomass fuel to heat water or steam, drive a steam turbine to generate electricity, or directly provide a heat source for the power generation and heating system to achieve power generation.

[0003] Among existing publicly available documents, patent publication number CN212204545U discloses a combustion boiler for biomass power generation. This technology involves a motor fixedly installed on the bottom wall of the boiler, with the motor's output shaft fixedly connected to a rotating disk. This device uses the rotation of the disk to disperse the incoming waste material through centrifugal force, thereby improving the efficiency of waste combustion. The automated discharge method avoids workers operating in high-temperature environments, increasing worker safety. However, this technology still has the following problems.

[0004] When biomass waste is processed in biomass incineration boilers in power plants, the biomass waste particles tend to accumulate in the furnace, forming localized dense areas. This obstructs airflow and causes uneven combustion reactions, making it difficult to achieve multi-directional, spaced combustion of biomass particles in the furnace. This accumulation state causes some particles to be discharged from the furnace without complete combustion, resulting in incomplete conversion of chemical energy into thermal energy. At the same time, the dense accumulation areas are prone to localized high-temperature coking, further hindering the combustion process and ultimately significantly reducing the thermal energy utilization rate of biomass incineration boilers.

The outer wall of the inner rod is fixed with a plurality of inner ring strips arranged in sequence from top to bottom. The inner rod and the inner ring strips slide along the circular hopper. A positioning post is fixed between the circular hopper and the bottom of the inner wall of the incinerator.

[0008] In a preferred embodiment, a gap is formed between the circular bucket and the polygonal bucket, and a plurality of outer ring plates are arranged equidistantly from top to bottom.

[0009] In a preferred embodiment, the upper surface of the bottom ring strip is rounded, and the cross-sectional area of ​​the upper surface of the bottom ring strip is smaller than the cross-sectional area of ​​its lower surface.

[0010] In a preferred embodiment, a plurality of connectors are fixed to the lower surface of the ring strip; A movable frame is fixed to the top of the connector. An outer bottom strip and an inner bottom strip are fixed to the upper surface of the movable frame, and the outer bottom strip is located inside the inner bottom strip. A rectangular bucket is slidably located on the outer wall of the outer bottom strip, and the inner bottom strip is slidably connected to the rectangular bucket. A slider slides on the outer wall of a rectangular bucket. The inner wall of the rectangular bucket has multiple grooves. Multiple rectangular bars are installed on the outer wall of the slider. The rectangular bars are arranged corresponding to the grooves. The rectangular bars and the moving frame are both fixedly connected to the slider. A reinforcing column is fixedly connected between the rectangular hopper and the bottom of the inner wall of the incinerator.

[0011] In a preferred embodiment, the cross-sectional area of ​​the outer bottom strip is larger than that of the inner bottom strip, and the upper surfaces of both the outer and inner bottom strips are rounded.

[0012] In a preferred embodiment, a support column is fixed between the polygonal hopper and the bottom of the inner wall of the incinerator, the support column being used to reinforce and support the polygonal hopper.

[0013] In a preferred embodiment, a door is hinged to the outer wall of the incinerator; A controller is installed on one side of the electric cylinder, and the controller is electrically connected to the electric cylinder. The controller has multiple covers on one side, which are threadedly connected to the incinerator. A steam box is located on one side of one of the covers, and the steam box is connected to the incinerator.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention utilizes a multi-directional distribution interval mechanism. Upon reaching a set time, an electric cylinder is activated to push the ring and concave bars downwards, causing the frame block to move the inner and outer polygonal bars downwards synchronously. This opens the polygonal slots at the bottom of the polygonal hopper, forming polygonal interval gaps. This allows biomass waste particles to be discharged from the bottom in multiple directions at intervals. Simultaneously, the frame block drives the connecting bars to move the polygonal baffle downwards, opening multiple polygonal holes. This allows the biomass waste particles to fall from the outer wall of the polygonal hopper in multiple directions. The biomass particles fall along the bottom and outer wall of the polygonal hopper in multiple directions at intervals, resulting in large dispersion gaps and thorough combustion. This achieves suspended multi-directional distribution interval combustion, significantly improving the thermal energy utilization rate of the biomass incineration boiler.

[0015] 2. This invention moves the concave strip downwards, simultaneously causing the moving block to move downwards. The moving block moves the bottom ring strip to open the bottom of the circular hopper, and the outer rod moves multiple outer ring plates downwards, opening multiple inner ring groove areas. At the same time, the inner rod moves multiple inner ring strips downwards, synchronously opening the inner inner ring grooves. This allows the biomass particles in the circular hopper to fall in layers along a multi-directional arc path from the bottom, outer wall, and inner wall. The particles have large dispersion gaps and sufficient contact with the combustion area at the bottom of the incinerator, achieving suspended multi-directional distributed interval combustion, which greatly improves the thermal energy utilization rate of the biomass incineration boiler.

[0016] 3. This invention uses the downward movement of the ring bar to simultaneously drive multiple connecting parts, causing the moving frame to move the outer and inner bottom bars downward, opening the bottom opening of the rectangular hopper. This allows biomass pellets to be discharged at intervals along a rectangular path to the bottom edge of the incinerator. At the same time, the moving frame drives the sliding bar and multiple rectangular bars downward, so that the rectangular bars no longer obstruct the outer wall of the rectangular hopper. The biomass pellets can then fall from multiple troughs at intervals along the rectangular path, resulting in a multi-directional distribution and interval combustion of the biomass pellets from the bottom and outer wall of the rectangular hopper. This leads to more complete combustion and significantly improves the thermal energy utilization rate of the biomass incineration boiler. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figure 1 - Figure 8 The diagram shows a high-efficiency power plant incineration boiler. This high-efficiency power plant incineration boiler is equipped with a multi-directional distribution interval mechanism. The multi-directional distribution interval mechanism allows biomass pellets to fall in a multi-directional interval along the bottom end and outer wall of the polygonal bucket 8, with large dispersion gaps, realizing suspended multi-directional distribution interval incineration, which greatly improves the thermal efficiency of the biomass incineration boiler. The specific structural configuration of the multi-directional distribution interval mechanism is as follows.

[0028] In this embodiment, as Figure 1 - Figure 5 As shown, an electric cylinder 2 is installed at the top of the incinerator 1. A ring bar 3 is fixedly connected to the output end of the electric cylinder 2. A multi-directional distribution spacing mechanism is installed on the inner wall of the ring bar 3. The multi-directional distribution spacing mechanism includes: a concave bar 4, fixedly installed on the inner wall of the ring bar 3, with a frame block 5 fixed to one top end of the concave bar 4; a polygonal inner bar 6, fixed to the upper surface of the frame block 5; a polygonal outer bar 7 fixed to the upper surface of the frame block 5 and outside the polygonal inner bar 6; a polygonal hopper 8 sliding on the outer wall of the polygonal outer bar 7, used to hold biomass waste pellets; multiple polygonal holes 9, all opened on the inner wall of the polygonal hopper 8, with a polygonal baffle 10 sliding on the outside of each polygonal hole 9; and a connecting bar 11, fixedly installed on the inner wall of the polygonal baffle 10, and fixedly connected to the frame block 5. The polygonal inner bar 6 is slidably connected to the polygonal hopper 8, and the frame block 5 is in contact with the bottom end of the polygonal hopper 8; the multiple polygonal baffles 10 and the connecting bar 11 are all slidably connected to the polygonal hopper 8.

[0029] When this technology is in use, the output end of the electric cylinder 2 moves down along the inner wall of the incinerator 1 to push the ring bar 3. The downward movement of the concave bar 4 will drive the frame block 5 to move down. The frame block 5 causes the polygonal inner bar 6 to move down. The polygonal inner bar 6 and the polygonal outer bar 7 can simultaneously open the polygonal slot at the bottom of the polygonal bucket 8. The frame block 5 drives the connecting bar 11 to move down. The connecting bar 11 drives multiple polygonal baffles 10 to move down. The polygonal baffles 10 open the polygonal hole 9 area. Biomass waste particles begin to fall from the multiple polygonal hole 9 areas in a multi-directional distribution on the outer wall to the incineration area at the bottom of the inner wall of the incinerator 1. In this way, the bottom of the polygonal bucket 8 and the outer wall achieve multi-directional interval falling and incineration according to the polygonal path, avoiding accumulation and achieving dispersed interval incineration.

[0030] In this technical solution, such as Figure 2 - Figure 6As shown, the polygonal bucket 8 is provided with a circular bucket 13 on its outside; a movable block 14 is fixed to the other end of the concave strip 4, and a bottom ring strip 15 is fixedly installed on the upper surface of the movable block 14, which slides and seals the bottom end of the circular bucket 13; an outer rod 16 slides on the outer wall of the circular bucket 13, and the bottom end of the outer rod 16 is fixedly connected to the movable block 14; multiple outer ring plates 17 are fixed on the outer wall of the outer rod 16, and multiple outer ring plates 17 slide along the outer wall of the circular bucket 13; multiple inner ring grooves 20 are opened on the inner groove wall of the circular bucket 13, and the outer ring plates 17 and inner ring grooves 20 are correspondingly arranged; an inner rod 18 is fixed to the bottom end of the inner wall of the concave strip 4, and multiple inner ring strips 19 are fixed on the outer wall of the inner rod 18 arranged sequentially from top to bottom, and the inner rod 18 and inner ring strips 19 slide along the circular bucket 13; a positioning post 28 is fixed between the circular bucket 13 and the bottom end of the inner wall of the incinerator 1. A gap is formed between the circular bucket 13 and the polygonal bucket 8, and multiple outer ring plates 17 are arranged equidistantly from top to bottom. The upper surface of the bottom ring bar 15 is rounded, and the cross-sectional area of ​​the upper surface of the bottom ring bar 15 is smaller than the cross-sectional area of ​​its lower surface.

[0031] When this technology is in use, the downward movement of the concave strip 4 will simultaneously drive the moving block 14 downward. The biomass waste particles inside the annular bucket 13 will begin to fall from the bottom along an arc path. The moving block 14 will cause the outer rod 16 to move downward, and the outer ring plate 17 will move downward along the outer wall of the annular bucket 13, so that the outer ring plate 17 no longer blocks the inner ring groove 20. The biomass waste particles fall into the incineration area along the multiple inner ring grooves 20 in an arc path. The inner rod 18 drives the multiple inner ring strips 19 to move downward synchronously. The inner ring strips 19 no longer block the inner ring groove 20 on the other side of the inner wall of the incineration box 1. The bottom, outer wall and inner wall of the annular bucket 13 achieve multi-directional arc path interval falling biomass waste particles, with larger dispersion gaps and more complete incineration.

[0032] In this technical solution, such as Figure 2 - Figure 8 As shown, multiple connectors 21 are fixed to the lower surface of the ring bar 3; a movable frame 22 is fixed to the top of the connectors 21, and an outer bottom bar 23 and an inner bottom bar 24 are fixed to the upper surface of the movable frame 22, with the outer bottom bar 23 located inside the inner bottom bar 24; a rectangular hopper 25 is slidably located on the outer wall of the outer bottom bar 23, and the inner bottom bar 24 is slidably connected to the rectangular hopper 25; a sliding bar 26 slides on the outer wall of the rectangular hopper 25, and multiple grooves are provided on the inner wall of the rectangular hopper 25; multiple rectangular bars 27 are installed on the outer wall of the sliding bar 26, with the rectangular bars 27 corresponding to the grooves; both the rectangular bars 27 and the movable frame 22 are fixedly connected to the sliding bar 26; a reinforcing column 30 is fixedly connected between the rectangular hopper 25 and the bottom of the inner wall of the incinerator 1. The cross-sectional area of ​​the outer bottom bar 23 is larger than that of the inner bottom bar 24, and the upper surfaces of both the outer bottom bar 23 and the inner bottom bar 24 are rounded.

[0033] When this technology is in use, the ring bar 3 will simultaneously drive multiple connectors 21 to move downwards, and the moving frame 22 will drive the outer bottom bar 23 and inner bottom bar 24 to move downwards. In this way, the biomass waste particles inside the rectangular bucket 25 will be discharged at intervals along the opening positions of the outer bottom bar 23 and inner bottom bar 24 in a rectangular path. The moving frame 22 causes the slide bar 26 to drive multiple rectangular bars 27 to move downwards simultaneously. The rectangular bars 27 no longer block the multiple grooves on the inner wall of the rectangular bucket 25, so that the biomass waste particles inside the rectangular bucket 25 can be discharged along the multiple grooves in a rectangular path. This ensures that the bottom and outer wall of the rectangular bucket 25 achieve multi-directional interval discharge of biomass waste particles in a rectangular path, resulting in more complete combustion and higher thermal energy utilization.

[0034] In this technical solution, such as Figure 2 As shown, a support column 29 is fixed between the polygonal bucket 8 and the bottom of the inner wall of the incinerator 1. The support column 29 is used to reinforce and support the polygonal bucket 8. The support column 29 provides a stable and reinforcing support to the polygonal bucket 8, preventing the polygonal bucket 8 from shaking.

[0035] In this technical solution, as shown in the figure, the outer wall of the incinerator 1 is hinged with a door 31; A controller 12 is installed on one side of the electric cylinder 2, and the controller 12 is electrically connected to the electric cylinder 2. The controller 12 activates the electric cylinder 2, which pushes the ring bar 3 downwards and opens the door 31, allowing biomass waste pellets to be poured into the incineration chamber 1. Multiple covers 32 are provided on one side of the controller 1, and the covers 32 are threadedly connected to the incineration chamber 1. A steam box 33 is located on one side of one of the covers 32 and is connected to the incineration chamber 1. By opening the multiple covers 32, the biomass waste pellets are placed at the bottom openings of the covers 32 and transported into the incineration chamber 1, where they can enter the polygonal hopper 8, the circular hopper 13, and the rectangular hopper 25. Simultaneously, the steam box 33 can transport steam to the power generation steam pipeline, realizing steam transport operations.

[0036] The working principle of the power plant incineration boiler with high thermal energy utilization rate of this invention is as follows: First, when placing biomass waste pellets, the present invention opens multiple covers 32 and places the biomass waste pellets at the bottom openings of the covers 32 respectively, allowing the biomass waste pellets to enter the polygonal hopper 8 and form a polygonal loading state. Simultaneously, the biomass waste pellets enter the annular hopper 13 and form a circular loading state, and can also enter multiple rectangular hoppers 25 to form a rectangular loading state. After loading is complete, the multiple covers 32 and the incineration chamber 1 can be closed. The steam chamber 33 contains water, and the steam pipe at the top of the steam chamber 33 is connected to the power generation steam transmission pipe. The exhaust valve at the top of the steam chamber 33 should also be opened.

[0037] After the staff opens the door 31, a small amount of pre-burned biomass waste particles are conveyed from the opening of the door 31 until they are placed inside the incineration box 1 for ignition and incineration.

[0038] Secondly, when performing polygonal multi-directional distributed interval incineration, the interval time is set to ten minutes by the controller 12. When the time set by the controller 12 reaches the set ten minutes, the electric cylinder 2 is immediately activated by the controller 12. The output end of the electric cylinder 2 moves down along the inner wall of the incineration box 1 to push the ring bar 3. The ring bar 3 drives the concave bar 4 to move down. The concave bar 4 moves down and drives the frame block 5 to move down. At this time, the support column 29 of the incineration box 1 provides a reinforcing support force to the bottom of the polygonal bucket 8. In this way, the frame block 5 causes the polygonal inner bar 6 to move down. At the same time, the frame block 5 drives the polygonal outer bar 7 to move down. The polygonal inner bar 6 and the polygonal outer bar 7 can open the polygonal slots at the bottom of the polygonal bucket 8 at the same time. Moreover, there are polygonal gaps between the polygonal inner bar 6 and the polygonal outer bar 7. The biomass waste particles inside the polygonal bucket 8 are discharged down from the bottom polygonal slots corresponding to the polygonal outer bar 7 and the polygonal inner bar 6 at intervals, and are discharged to the incineration area at the bottom of the inner wall of the incineration box 1.

[0039] Simultaneously, frame block 5 moves connecting strip 11 downwards, which in turn moves multiple polygonal baffles 10 downwards. The polygonal baffles 10 open the polygonal hole 9 area, allowing the biomass waste particles inside the polygonal bucket 8 to begin falling from the multiple polygonal holes 9 area in a multi-directional distribution along the outer wall to the combustion area at the bottom of the inner wall of the incinerator 1. In this way, the bottom and outer wall of the polygonal bucket 8 achieve multi-directional, spaced falling combustion along a polygonal path, resulting in larger dispersion gaps between the falling biomass waste particles and more complete combustion.

[0040] Simultaneously, during the circular multi-directional distributed interval incineration of this invention, when the concave strip 4 moves downward, it simultaneously drives the moving block 14 downward. At the same time, the incineration box 1 supports the positioning column 28, which supports the circular bucket 13. The moving block 14 causes the bottom ring strip 15 to move downward, so that the biomass waste particles inside the circular bucket 13 begin to fall from the bottom in an arc path. At the same time, the moving block 14 causes the outer rod 16 to move downward, and the outer rod 16 causes multiple outer ring plates 17 to move downward synchronously. The outer ring plates 17 move downward along the outer wall of the circular bucket 13, so that the outer ring plates 17 no longer block the inner ring groove 20. This opens the area of ​​the inner ring groove 20, and the biomass waste particles on the inner wall of the circular bucket 13 fall into the incineration area along the multiple inner ring grooves 20 in an arc path. Simultaneously, the concave strip 4 drives the inner rod 18 to move downward, and the inner rod 18 drives multiple inner ring strips 19 to move downward synchronously. The inner ring strips 19 no longer block the inner ring grooves 20 on the other side of the inner wall of the incinerator 1. In this way, the biomass waste particles inside the circular bucket 13 begin to fall and be discharged in layers from the multiple inner ring grooves 20 on the inner wall. Thus, the bottom, outer wall and inner wall of the circular bucket 13 achieve a multi-directional arc path for the biomass waste particles to fall at intervals. The biomass waste particles are dispersed and fully contact the incineration area at the bottom of the inner wall of the incinerator 1 for combustion. The falling and dispersion gaps of the biomass waste particles are large, and the combustion is more complete.

[0041] Simultaneously, during rectangular multi-directional distributed interval incineration, when the ring bar 3 moves downward, it synchronously drives multiple connecting parts 21 to move downward. The connecting parts 21 cause the moving frame 22 to move downward, which in turn drives the outer bottom bar 23 and inner bottom bar 24 to move downward. In this way, the biomass waste particles inside the rectangular hopper 25 are discharged downward along the opening positions of the outer bottom bar 23 and inner bottom bar 24 in a rectangular path, discharging to the edge incineration area at the bottom of the inner wall of the incineration chamber 1. At the same time, the moving frame 22 drives the sliding bar 26 to move downward, and the sliding bar 26 drives multiple rectangular bars 27 to move downward synchronously. As the rectangular bar 27 and the sliding bar 26 move downwards, they slide down along the outer wall of the rectangular hopper 25. The rectangular bar 27 no longer obstructs the multiple grooves on the inner wall of the rectangular hopper 25, allowing the biomass waste particles inside the rectangular hopper 25 to fall along the multiple grooves in a rectangular path. This causes the biomass waste particles to fall to the edge of the incineration area at the bottom of the inner wall of the incineration chamber 1. In this way, the bottom and outer wall of the rectangular hopper 25 achieve multi-directional and spaced falling of biomass waste particles along a rectangular path, resulting in a larger dispersion gap between the falling biomass waste particles and more complete combustion.

[0042] After 20 seconds of timing for feeding, the controller 12 continues to start the electric cylinder 2. The electric cylinder 2 drives the ring bar 3 to move upward and reset. The ring bar 3 drives the concave bar 4 to move the frame block 5 upward. The frame block 5 drives the polygonal inner bar 6 and the polygonal outer bar 7 to continue to block the bottom area of ​​the polygonal bucket 8. At the same time, the frame block 5 drives the connecting bar 11 to move multiple polygonal baffles 10 upward and reset. The multiple polygonal baffles 10 block the outer wall of the polygonal bucket 8.

[0043] Simultaneously, the concave strip 4 drives the moving block 14 upward, and the moving block 14 drives the bottom ring strip 15 to seal the bottom area of ​​the circular bucket 13. At the same time, the moving block 14 drives the outer rod 16 to move multiple outer ring plates 17 upward, and the outer ring plates 17 seal the outer wall of the circular bucket 13. Simultaneously, the ring strip 3 causes multiple connecting pieces 21 to move upward, and the connecting pieces 21 drive the moving frame 22 to move the outer bottom strip 23 and inner bottom strip 24 upward synchronously, and the outer bottom strip 23 and inner bottom strip 24 seal the bottom of the rectangular bucket 25. At the same time, the incineration box 1 supports the reinforcing column 30, which supports the rectangular bucket 25 and improves the stability of the rectangular bucket 25. Simultaneously, the moving frame 22 drives the sliding strip 26 to move multiple rectangular strips 27 upward synchronously, and the multiple rectangular strips 27 can seal the outer wall of the rectangular bucket 25. In this way, biomass waste particles can be suspended and distributed in a multi-directional interval for incineration at specified intervals. The flue gas from combustion is discharged upwards through the exhaust valve at the top of the steam box 33, while simultaneously heating the steam box 33. After being heated, the steam is transported to the designated power generation area through the power generation steam delivery pipeline.
