Description

Technical Field

[0001] This invention belongs to the field of biomass fluidized bed boiler technology, specifically referring to a biomass fluidized bed boiler slag storage device. Background Technology

[0002] Biomass fuel power generation is a renewable energy technology that utilizes biomass resources to convert them into electricity. It converts the chemical energy in biomass into electrical energy through combustion, gasification, anaerobic fermentation, and other methods. It has advantages such as low carbon emissions, environmental protection, and resource recycling. It mainly uses agricultural and forestry waste as fuel, such as straw, rice husks, wood processing waste, branches, and sawdust.

[0003] Biomass fluidized bed boilers are a type of high-efficiency, clean combustion equipment specifically designed for burning biomass fuels (such as straw, sawdust, rice husks, agricultural and forestry waste, etc.), achieving high-efficiency combustion and low-pollution emissions through fluidization technology.

[0004] After biomass fuel is burned in a fluidized bed boiler, the waste residue is looser in texture than coal waste residue, requiring more space for storage. Furthermore, biomass fuel waste residue is generally at a high temperature after being discharged from the boiler, requiring a drum slag cooler to cool it down before being transported to a storage device for future reuse. However, even after being cooled by the drum slag cooler, the waste residue still has a high temperature (80-90℃), so the waste residue storage device still needs to use a thicker insulation layer, increasing equipment costs. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a biomass fluidized bed boiler slag storage device, which at least partially solves the above problems.

[0006] The technical solution adopted by this invention is as follows: This invention proposes a biomass fluidized bed boiler slag storage device, comprising:

[0007] A storage tank, wherein a double conical disc is provided inside the storage tank and is coaxial with it, and an annular material discharge gap is formed between the storage tank and the double conical disc;

[0008] A winch is installed on top of the storage tank, and the winding end of the winch is wound with a traction rope connected to the double cone disc;

[0009] The inner wall of the double cone disk is provided with a cone-shaped cover, and a heat exchange chamber capable of storing water is provided between the double cone disk and the cone-shaped cover. Limiting pipes are provided on both sides of the double cone disk. The first ends of the two limiting pipes are respectively connected to the inner sides of the heat exchange chamber, and the second ends of the two limiting pipes are respectively connected to a cold water conveying device and a hot water storage device.

[0010] Furthermore, a temperature sensor is connected to the conical cover, and the detection end of the temperature sensor extends into the heat exchange chamber for real-time detection of the water temperature in the heat exchange chamber.

[0011] Furthermore, a force gauge is provided at one end of the traction rope connected to the double cone disc to detect the tension of the traction rope in real time.

[0012] Furthermore, the second end of the limiting tube slides through and extends to the top outer side of the storage tank.

[0013] Furthermore, the interior of the double-cone disk is also equipped with a vibration motor capable of driving the double-cone disk to vibrate.

[0014] Furthermore, the sidewall of the double-cone disk is provided with a mounting hole, the limiting tube extends from the mounting hole into the double-cone disk, and a buffer pad for buffering vibration is provided between the limiting tube and the mounting hole.

[0015] Furthermore, a flexible tube is connected to one end of the limiting tube extending into the double cone disk, and the limiting tube is connected to the heat exchange chamber through the flexible tube.

[0016] Furthermore, the interior of the double-cone disk is provided with two conical covers, which are respectively located at the conical portions at both ends of the double-cone disk, forming two heat exchange chambers. The flexible hose is connected to the two heat exchange chambers through a three-way pipe.

[0017] Furthermore, the top of the storage tank is provided with a feed inlet for feeding materials into the storage tank.

[0018] Furthermore, the bottom of the storage tank is provided with a discharge port for discharging materials, and a valve is connected to the discharge port.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows:

[0020] 1. By installing a double cone disc inside the storage tank, and the double cone disc being raised and lowered by a winch, the waste slag fed in through the feed inlet falls into the storage tank below the double cone disc through the material drop gap. After the waste slag is fed in, the double cone disc descends and rests on the waste slag. The weight of the double cone disc is used to compact the loose waste slag, thereby increasing the waste slag storage capacity of the storage tank.

[0021] 2. By setting a heat exchange chamber inside the double cone plate and setting a limiting pipe connecting the cold water conveying equipment and the hot water storage equipment, water is conveyed into the heat exchange chamber during the process of compacting the waste residue by the double cone plate. The high temperature waste residue can heat the water inside the heat exchange chamber at the bottom of the double cone plate, reducing the energy required for the subsequent boiler to heat the water to generate steam, reducing energy consumption, and at the same time cooling the slag, thereby reducing the wall thickness of the storage tank.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] like Figure 1 and Figure 2As shown, the present invention proposes a biomass fluidized bed boiler slag storage device, including a storage tank 1, a double cone disk 2 and a winch 3. The double cone disk 2 is disposed inside the storage tank 1. The storage tank 1 and the double cone disk 2 are arranged coaxially with each other, and an annular material drop gap 101 is formed between the storage tank 1 and the double cone disk 2.

[0032] In a specific embodiment, the top of the storage tank 1 is provided with a feed inlet 11 for feeding materials into the storage tank 1, and the feed inlet 11 and the double cone disk 2 are coaxially arranged, so that the waste residue fed in through the feed inlet 11 can fall into the center of the top cone of the double cone disk 2, be fully dispersed by the cone surface, and fall evenly into the storage tank 1 through the material drop gap 101.

[0033] The bottom of the storage tank 1 is provided with a discharge port 12 for discharging materials, and a valve is connected to the discharge port 12. The discharge of materials from the discharge port 12 is controlled by opening / closing the valve.

[0034] Furthermore, the top of storage tank 1 is designed as a horizontal structure to provide a horizontal installation platform for the equipment, and the bottom of storage tank 1 is designed as a conical funnel-shaped mechanism so that the waste residue inside storage tank 1 can gather towards the center when discharged, avoiding dead corners that would lead to incomplete discharge.

[0035] The winch 3 is installed on top of the storage tank 1, and the winding end of the winch 3 is wound with a traction rope 31. One end of the traction rope 31 is connected to the double cone disc 2. The double cone disc 2 is lifted and lowered by the winch 3 winding / unwinding the traction rope 31.

[0036] When waste residue is added into storage tank 1, the double cone disk 2 is lifted upward so that the waste residue falls into storage tank 1 through the material drop gap 101. After the waste residue is added, the double cone disk 2 is lowered and placed on the waste residue. The loose waste residue is compacted by the weight of the double cone disk 2.

[0037] Combination Figure 3 As shown, the double cone disk 2 is also equipped with a vibration motor 24 that can drive the double cone disk 2 to vibrate. When the double cone disk 2 compacts the waste residue by its own weight, the vibration motor 24 drives the double cone disk 2 to vibrate, and the waste residue can be fully compacted by the excitation force.

[0038] Thus, when biomass fuel waste is conveyed into storage tank 1, winch 3 first lifts double cone disc 2 upward by winding traction rope 31. Then, biomass fuel waste is lifted to the top of storage tank 1 by the elevator and then put into storage tank 1 through feed inlet 11. Since feed inlet 11 and double cone disc 2 are coaxially set, the waste can fall to the center of the top cone of double cone disc 2 and be fully dispersed by the cone surface. Then, it falls into the storage tank 1 through the material drop gap 101 between storage tank 1 and double cone disc 2. After the waste is conveyed, winch 3 releases traction rope 31, causing double cone disc 2 to fall and land on the waste. The weight of double cone disc 2 is used to compact the loose waste. At the same time, vibrating motor 24 drives double cone disc 2 to vibrate. The vibration force can fully compact the waste and increase the waste storage capacity of storage tank 1.

[0039] By repeating the above steps, the loose waste residue can be compacted by the double cone disc 2 each time it is added, thereby increasing the waste residue storage capacity of the storage tank 1.

[0040] Combination Figure 4 As shown, a tension gauge 32 is provided at one end of the traction rope 31 connected to the double cone disc 2 to detect the tension of the traction rope 31 in real time. When the double cone disc 2 falls on the waste residue and is completely supported by the waste residue, the traction rope 31 is not subjected to the tension of the double cone disc 2's own weight. At this time, the tension gauge 32 cannot detect the tension. Therefore, when the tension gauge 32 cannot detect the tension value, that is, when the double cone disc 2 is completely supported by the waste residue, the winch 3 stops releasing the traction rope 31.

[0041] As the waste residue is gradually compacted, the height of the double cone disc 2 decreases. When the waste residue can no longer fully support the double cone disc 2, the traction rope 31 is subjected to tension again due to the weight of the double cone disc 2. Correspondingly, the tension gauge 32 detects the tension. At this time, the winch 3 lowers the traction rope 31 until the double cone disc 2 is supported by the waste residue again, and the tension gauge 32 can no longer detect the tension value.

[0042] It should be noted that each time the winch 3 lifts the double cone disc 2, it lifts the double cone disc 2 to its highest position without obstructing the feed inlet 11.

[0043] Combination Figure 2 , Figure 3 and Figure 4 As shown, a touch switch 26 is provided on one side of the top of the double cone disk 2. When the double cone disk 2 is lifted upwards until the touch switch 26 touches the top of the storage tank 1, the winch 3 stops winding the traction rope 31, and the double cone disk 2 stops rising (i.e., reaches the highest point).

[0044] Combination Figure 2 and Figure 3As shown, the inner wall of the double cone disk 2 is provided with a cone-shaped cover 21, and a heat exchange chamber 201 capable of storing water is provided between the double cone disk 2 and the cone-shaped cover 21. Limiting pipes 4 are provided on both sides of the double cone disk 2. The first ends of the two limiting pipes 4 are respectively connected to the inner sides of the heat exchange chamber 201, and the second ends of the two limiting pipes 4 are respectively connected to a cold water conveying device and a hot water storage device. The cold water conveying device conveys water into the heat exchange chamber 201 through the limiting pipes 4 connected to it, and the water in the heat exchange chamber 201 can be conveyed to the hot water storage device through the limiting pipes 4 connected to the hot water storage device.

[0045] In this embodiment, the heat exchange chamber 201 is located at the bottom of the double cone disk 2. During the process of the double cone disk 2 compacting the waste residue, the bottom of the double cone disk 2 comes into contact with the high-temperature waste residue, so that the high-temperature waste residue can heat the water inside the heat exchange chamber 201 at the bottom of the double cone disk 2.

[0046] In this way, the cold water conveying equipment delivers room temperature water into the heat exchange chamber 201 through a limiting pipe 4. During the process of the double cone plate 2 compacting the waste residue, the residual heat of the waste residue is used to heat the room temperature water in the heat exchange chamber 201. At the same time, the hot water in the heat exchange chamber 201 is pumped to the hot water storage device through another limiting pipe 4 using the water pump built into the hot water storage device, thereby reducing the energy required for the subsequent boiler to heat the water to generate steam and reducing energy consumption.

[0047] Furthermore, as the amount of waste residue increases, the height of the double cone disk 2 gradually rises, ensuring that the double cone disk 2 is always in contact with the newly added high-temperature waste residue on the upper layer, thereby heating the water in the heat exchange chamber 201 to the specified temperature.

[0048] The water in the heat exchange chamber 201 can increase the weight of the double cone disk 2 and improve the compaction effect of the double cone disk 2 on the waste residue.

[0049] Combination Figure 4 As shown, a temperature sensor 23 is connected to the conical cover 21. The detection end of the temperature sensor 23 extends into the heat exchange chamber 201, which can detect the water temperature in the heat exchange chamber 201 in real time.

[0050] Thus, the temperature of the water in the heat exchange chamber 201 is detected in real time by the temperature sensor 23. When the slag temperature is high and the heating effect is good, the water temperature is also high, which can increase the water inlet and outlet rates into the heat exchange chamber 201 and increase the amount of water heated. When the slag temperature is low and the heating effect is poor, the water temperature decreases, which can decrease the water inlet and outlet rates into the heat exchange chamber 201 and increase the heating time of the water in the heat exchange chamber 201, so that the water can be heated to the specified temperature. The water inlet and outlet rates of the heat exchange chamber 201 are adjusted in real time according to the detection data of the temperature sensor 23.

[0051] Combination Figure 2 and Figure 3As shown, the second end of the limiting tube 4 slides through and extends to the top outside of the storage tank 1. The top of the storage tank 1 is provided with a sliding sleeve corresponding to the limiting tube 4. The limiting tube 4 slides along the sliding sleeve. The limiting tube 4 is made of a rigid pipe with a large diameter and thick wall, so that the limiting tube 4 can not only transport water, but also guide the up and down movement of the double cone plate 2, so as to avoid horizontal deviation during the up and down movement of the double cone plate 2.

[0052] It should be noted that the vertical section length of the limiting tube 4 is the same as the maximum moving distance of the double cone disk 2, and the limiting tube 4 will not interfere with the up and down movement of the double cone disk 2.

[0053] Because the limiting pipe 4 is made of rigid pipe, the top of the limiting pipe 4 will move with the movement of the double cone plate 2. Correspondingly, the two limiting pipes 4 are connected to the cold water conveying equipment and the hot water storage equipment through flexible hoses, so that the limiting pipe 4 can still maintain a stable connection with the cold water conveying equipment and the hot water storage equipment during the movement.

[0054] Combination Figure 3 and Figure 5 As shown, the side wall of the double cone disk 2 is provided with a mounting hole 202, and the limiting tube 4 extends from the mounting hole 202 into the double cone disk 2, so that the limiting tube 4 is connected to the double cone disk 2.

[0055] The diameter of the mounting hole 202 is larger than the diameter of the limiting tube 4, so that there is an annular gap between the inner wall of the mounting hole 202 and the outer wall of the limiting tube 4. A buffer pad 25 that can absorb vibration is set in the annular gap between the limiting tube 4 and the mounting hole 202, that is, the double cone disk 2 is movably connected to the limiting tube 4 through the buffer pad 25.

[0056] Thus, when the vibrating motor 24 drives the double cone disc 2 to vibrate and compact the waste residue, the vibration of the double cone disc 2 can be absorbed by the buffer pad 25, so that the vibration cannot be transmitted to the limiting tube 4, maintaining the guiding accuracy of the limiting tube 4 and avoiding the sliding and jamming of the limiting tube 4 due to vibration deformation. In addition, since the traction rope 31 is a flexible rope, it also has a certain buffering effect. Therefore, the vibration of the double cone disc 2 will not be transmitted to the storage tank 1 through the traction rope 31.

[0057] In an optional embodiment, the distance between the mounting hole 202 and the limiting tube 4 is 3.0-5.0 cm. Accordingly, a larger size buffer pad 25 can be used, so that the buffer pad 25 has sufficient deformation buffer distance and better absorbs vibration.

[0058] Combination Figure 5 As shown, one end of the limiting tube 4 extending into the double cone disk 2 is connected to a flexible tube 41. The limiting tube 4 is connected to the heat exchange chamber 201 through the flexible tube 41. Since the flexible tube 41 has good deformability, its connection is not affected by small-amplitude vibration.

[0059] When the vibrating motor 24 drives the double cone disk 2 to vibrate and compact the waste residue, the heat exchange chamber 201 also vibrates synchronously. Therefore, by using a flexible hose 41 to connect the limiting pipe 4 and the heat exchange chamber 201, the water connection between the limiting pipe 4 and the heat exchange chamber 201 can be stably maintained when the heat exchange chamber 201 vibrates.

[0060] Combination Figure 3 and Figure 4 As shown, the interior of the double cone disk 2 is provided with two conical covers 21, which are respectively set at the conical parts at both ends of the double cone disk 2, forming two heat exchange chambers 201. The flexible hose 41 is connected to the two heat exchange chambers 201 through the three-way pipe 22. By using two conical covers 21 to form two heat exchange chambers 201, the heat exchange area can be increased.

[0061] In this embodiment, heat exchange chambers 201 are provided at both the top and bottom of the double cone disk 2. High-temperature waste residue covers both the top and bottom of the double cone disk 2. Before conveying the high-temperature waste residue into the storage tank 1 again, the double cone disk 2 is first lifted upwards, and the vibration motor 24 drives the double cone disk 2 to vibrate. Under the action of vibration, the waste residue above the double cone disk 2 falls below the double cone disk 2. Then the double cone disk 2 is lowered onto the waste residue. At this time, new high-temperature waste residue is added. The newly added high-temperature waste residue covers the top of the double cone disk 2 and can exchange heat with the heat exchange chamber 201 at the top of the double cone disk 2. The heat exchange chamber 201 at the bottom of the double cone disk 2 can exchange heat with the previously added waste residue. At the same time, the water in the two heat exchange chambers 201 is heated to improve the waste heat utilization rate.

[0062] Furthermore, as the amount of waste residue increases, the height of the double cone disk 2 gradually rises, ensuring that the double cone disk 2 is always in contact with the newly added high-temperature waste residue on the upper layer, thereby heating the water in the heat exchange chamber 201 to the specified temperature.

[0063] The working principle of this invention: High-temperature waste residue simultaneously covers the top and bottom of the double cone disk 2. The cold water conveying device delivers room temperature water into the heat exchange chamber 201 through a limiting pipe 4. During the process of the double cone disk 2 compacting the waste residue, the residual heat of the waste residue is used to heat the room temperature water in the heat exchange chamber 201. At the same time, the hot water storage device uses its own water pump and another limiting pipe 4 to pump the hot water in the heat exchange chamber 201 into the storage device for storage.

[0064] Before feeding high-temperature waste residue into storage tank 1 again, winch 3 first lifts double cone disk 2 upward by winding traction rope 31. Vibration motor 24 drives double cone disk 2 to vibrate. Under the action of vibration, the waste residue above double cone disk 2 falls into the lower part of double cone disk 2 through the material drop gap 101. Then winch 3 releases traction rope 31 to make double cone disk 2 fall and land on waste residue until double cone disk 2 is completely supported by waste residue, that is, the tension gauge 32 can no longer detect the tension value. At this time, winch 3 stops releasing traction rope 31 and then feeds in new high-temperature waste residue. The newly fed high-temperature waste residue covers the top of double cone disk 2 and can exchange heat with the heat exchange chamber 201 at the top of double cone disk 2. The heat exchange chamber 201 at the bottom of double cone disk 2 can exchange heat with the waste residue fed in last time. At the same time, the water in the two heat exchange chambers 201 is heated to improve the waste heat utilization rate.

[0065] Under the weight of the double cone disc 2 and the action of the vibration motor 24, the waste slag below the double cone disc 2 is gradually compacted. As the waste slag is gradually compacted, the height of the double cone disc 2 decreases. When the waste slag can no longer fully support the double cone disc 2, the traction rope 31 is affected by the weight of the double cone disc 2 and is subjected to tension again. Correspondingly, the tension gauge 32 detects the tension. At this time, the winch 3 lowers the traction rope 31 until the double cone disc 2 is supported by the waste slag again, that is, the tension gauge 32 can no longer detect the tension value.

[0066] By repeating the above steps, the loose waste residue can be compacted by the double cone disc 2 each time it is added, thereby increasing the waste residue storage capacity of the storage tank 1.

[0067] In summary, the above embodiments are as follows: by setting a double cone disk 2 inside the storage tank 1, and the double cone disk 2 is controlled to rise and fall by a winch 3, the waste slag fed in through the feed port 11 falls into the storage tank 1 below the double cone disk 2 through the material drop gap 101. After the waste slag is fed in, the double cone disk 2 descends and falls onto the waste slag, and the loose waste slag is compacted by the weight of the double cone disk 2.

[0068] By installing a vibration motor 24 inside the double cone disk 2, when the double cone disk 2 compacts the waste residue by its own weight, the vibration motor 24 drives the double cone disk 2 to vibrate, and the waste residue can be fully compacted by the excitation force.

[0069] By setting a heat exchange chamber 201 inside the double cone disk 2 and setting a limiting pipe 4 connecting the cold water conveying equipment and the hot water storage equipment, water is conveyed into the heat exchange chamber 201 during the process of compacting the waste residue by the double cone disk 2. The high temperature waste residue can heat the water inside the heat exchange chamber 201 at the bottom of the double cone disk 2, reducing the energy required for the subsequent boiler to heat the water to generate steam and reducing energy consumption.
