Description

Technical Field

[0001] This invention relates to the field of boiler equipment technology, and in particular to a high-efficiency and energy-saving boiler equipment with ash removal function. Background Technology

[0002] A boiler is an energy conversion device that is mainly used to convert the chemical energy of fuel into thermal energy and then transfer the thermal energy through working fluids such as steam or hot water to meet various needs such as industrial production, power generation, and heating.

[0003] The patent with announcement number CN221881788U discloses a high-efficiency and energy-saving boiler, which includes an insulated shell, a boiler body fixedly connected to the inner wall of the insulated shell, a furnace shell fixedly connected to the inner wall of the bottom end of the boiler body, a burner fixedly connected to the bottom end of the insulated shell, a fuel inlet of the burner fixed at the bottom left side of the insulated shell, and a burner output pipe passing through the boiler body and fixedly connected to the bottom of the furnace shell.

[0004] In the above case, fuel combustion takes place inside the furnace, and then the flue gas is discharged into the lower smoke chamber sequentially through the connecting pipe, the five-row pipe, and the guide pipe. It then enters the central plate through the round pipe and is finally discharged from the exhaust pipe. It uses gravity to allow the ash accumulated in the lower smoke chamber to be discharged from the outlet valve. However, it cannot ensure that all the ash in the lower smoke chamber will automatically slide out from a single outlet valve by gravity alone. At the same time, the ash inside the connecting pipe, the five-row pipe, and the guide pipe is difficult to handle and is prone to clogging the pipes. Furthermore, the flue gas is discharged directly from the exhaust pipe, and the dust attached to it will pollute the environment, reducing the practicality of the equipment.

[0005] Therefore, the present invention provides a high-efficiency and energy-saving boiler with ash removal function to meet the requirements. Summary of the Invention

[0006] The purpose of this invention is to provide a high-efficiency and energy-saving boiler with ash removal function to solve the problems mentioned in the background art.

[0009] In a preferred embodiment, the top of the transfer cylinder is slidably connected to several inner smoke pipes, the other end of which passes through the boiler outer liner near the left smoke box, and the ends of all the inner smoke pipes located outside the boiler outer liner are slidably connected to the same inner seat.

[0010] In a preferred embodiment, the inner seat is fixedly connected to the outside of the boiler outer liner, and the flue gas assembly includes two outer seats that are fixedly connected to the top two ends of the side of the boiler outer liner near the inner seat. Several outer flue pipes are slidably connected to the inner side of the outer seats, and their other ends extend into the inside of the boiler outer liner and pass through the other end of the boiler outer liner.

[0011] In a preferred embodiment, both the inner and outer smoke pipes include a mounting ring fixedly connected to one end near the left smoke box, which is bolted to the outer side of the corresponding inner or outer seat. The outer side of the boiler outer liner and the inner side of the central rotating cylinder are fixedly connected with retaining rings whose position and shape are adapted to the inner and outer smoke pipes.

[0012] In a preferred embodiment, there are five inner smoke pipes and three outer smoke pipes on the same inner side of the outer seat. The inner and outer diameters of the inner and outer smoke pipes are the same. An inner support plate and a support frame are fixedly connected to the inner side of the boiler outer shell. The bottom end of the inner smoke pipe is tightly fitted to the top end of the inner support plate. All outer smoke pipes are fixedly connected to the inner side of the support frame.

[0013] In a preferred embodiment, the filter assembly includes an outer threaded ring bolted to the inside of the exhaust pipe at the end away from the right smoke box. The inner side of the outer threaded ring is fixedly connected to a connecting pipe, and the outer side of the outer threaded ring, near the right smoke box, is tightly fitted to the inside of the exhaust pipe.

[0014] In a preferred embodiment, the connecting pipe is fixedly connected to a sealing ring on the outer side of the exhaust pipe, and is tightly fitted to the side of the exhaust pipe away from the right smoke box. A filter pipe is fixedly connected to the side of the connecting pipe away from the exhaust pipe.

[0015] In a preferred embodiment, a filter element is slidably connected to the inside of the filter tube, and a fixing cap is threadedly connected to the end of the filter tube away from the connecting pipe, which abuts against the side of the filter element away from the connecting pipe.

[0016] In a preferred embodiment, the boiler outer shell includes an insulation shell fixedly connected to the outside. A water inlet valve and a steam valve are fixedly connected to the two ends of the top of the boiler outer shell, respectively.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting up a left smoke box, a right smoke box, a cover, and a connecting pipe, allows the left and right smoke boxes to be opened using the cover, facilitating cleaning of their interiors. Simultaneously, the burner can be bolted off, and then an external scraper can be inserted through the connecting pipe into the furnace to directly clean the accumulated ash on the inner wall. The scraped-off ash can slide directly out of the equipment due to the inclined design of the furnace, making the equipment easy to clean and reducing maintenance difficulty. Furthermore, the removal of ash reduces the load on the boiler equipment itself, saving energy and thus improving work efficiency.

[0018] This invention, by setting up a transfer component and a smoke exhaust component, allows the inner and outer smoke pipes to be fixed to the inner and outer seats by mounting rings, facilitating quick assembly and disassembly of the inner and outer smoke pipes. The sliding tracks of the inner and outer smoke pipes are limited by the support frame and inner support plate, and are further fixed by retaining rings. This allows the inner and outer smoke pipes to be cleaned and replaced at any time when they are blocked or require maintenance, improving the maintenance efficiency and service life of the equipment.

[0019] This invention, by setting up a filtration assembly, uses a filter element and activated carbon plate to filter the flue gas discharged from the exhaust pipe, preventing the flue gas from being directly discharged and polluting the external environment. The external threaded ring and sealing ring facilitate the disassembly and assembly of the filter tube while ensuring the airtightness between the filter tube and the exhaust pipe. The filter tube can be opened and closed by the fixed cover, and the internal filter element can be disassembled and installed, making it easy to replace and clean the filter element and activated carbon plate, thus improving the practicality of the equipment.

[0020] This invention, by setting up an outflow pipe and a level pipe, allows water to enter the boiler outer tank through the outflow pipe and then into the level pipe. The water level inside the boiler outer tank can be directly observed through a scale window, enabling operators to intuitively see the amount of water inside the equipment and adjust the water volume accordingly, thus ensuring the practicality of the equipment.

[0023] The present invention will be further described below with reference to embodiments.

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Please see Figures 1-6 This invention provides a high-efficiency and energy-saving boiler with ash removal function, including a boiler outer liner 1. An inclined furnace liner 2 is fixedly connected to the bottom of the inner side of the boiler outer liner 1. A transfer assembly is fixedly connected to the other end of the furnace liner 2, with the other end extending through the boiler outer liner 1. Smoke exhaust assemblies are fixedly connected to both ends of the top inner side of the boiler outer liner 1. A left smoke box 11 and a right smoke box 12 are fixedly connected to both sides of the boiler outer liner 1, respectively. A connecting pipe 14 is fixedly connected to the inner side of the bottom of the left smoke box 11, and is fixedly connected to the furnace liner 2. The transfer assembly includes a transfer cylinder 3 fixedly connected to the inner side of the boiler outer liner 1 near the right smoke box 12. The inclined upward end of the furnace liner 2 is fixedly connected to the bottom end of the transfer cylinder 3 away from the right smoke box 12. Several inner smoke pipes 6 are slidably connected to the top of the transfer cylinder 3. The other end of the flue pipe 6 passes through the end of the boiler outer liner 1 near the left smoke box 11. All the inner flue pipes 6 are slidably connected to the same inner seat 4 at the end outside the boiler outer liner 1. The inner seat 4 is fixedly connected to the outside of the boiler outer liner 1. The exhaust assembly includes two outer seats 5 that are fixedly connected to the top two ends of the side of the boiler outer liner 1 near the inner seat 4. Several outer flue pipes 31 are slidably connected to the inner side of the outer seat 5. Their other ends extend into the interior of the boiler outer liner 1 and pass through the other end of the boiler outer liner 1. The boiler outer liner 1 includes a heat insulation shell 16 fixedly connected to the outside. The top two ends of the boiler outer liner 1 are fixedly connected to a water inlet valve 17 and a steam valve 18, respectively. A support 22 is fixedly connected to the bottom of the heat insulation shell 16. A burner 15 is bolted to the outside of the left smoke box 11. Its output end extends to the inside of the connecting pipe 14.

[0026] A suitable amount of water is injected into the outer boiler chamber 1 through the water inlet valve 17. The burner 15 is started, and fuel and air are blown into the furnace chamber 2 for combustion. Heat is transferred from the furnace chamber 2 to the water outside to heat the water. At the same time, the high-temperature flue gas generated by combustion enters the central transfer cylinder 3 from the furnace chamber 2, then enters each inner smoke pipe 6, and then enters the left smoke box 11 from the other end of the inner smoke pipe 6. Then it enters the outer smoke pipe 31 from the left smoke box 11.

[0027] Please see Figures 1-6Both the left smoke box 11 and the right smoke box 12 have a cover 13 hinged to the end furthest from the boiler outer liner 1. The upper and lower ends of the outer side of the boiler outer liner 1 are fixedly connected to an outlet pipe 20. The other ends of the two outlet pipes 20 are fixedly connected to the same liquid level pipe 21, which includes a scale window fixedly connected to the inside. The inner smoke pipe 6 and the outer smoke pipe 31 both include a mounting ring 7 fixedly connected to the end near the left smoke box 11, which is bolted to the outside of the corresponding inner seat 4 or outer seat 5. The outer side of the boiler outer liner 1 and the inner side of the central rotating cylinder 3 are fixedly connected to the inner smoke pipe 6 and the outer smoke pipe, respectively. The number of inner smoke pipes 6 is five, and the number of outer smoke pipes 31 inside the same outer seat 5 is three. The inner and outer diameters of the inner smoke pipes 6 and the outer smoke pipes 31 are the same. The inner support plate 8 and the support frame 9 are fixedly connected to the inner side of the boiler outer shell 1. The bottom end of the inner smoke pipe 6 is tightly fitted to the top end of the inner support plate 8. All outer smoke pipes 31 are fixedly connected to the inner side of the support frame 9. The left smoke box 11, the right smoke box 12 and the box cover 13 are fixedly connected to the inner side of the matching isolation rings. The boiler outer shell 1, the left smoke box 11, the right smoke box 12 and the heat insulation shell 16 are all made of heat insulation material.

[0028] When the high-temperature flue gas flows in the inner flue pipe 6 and the outer flue pipe 31, it exchanges heat with the water in the outer boiler shell 1, allowing the water to fully absorb the heat from the flue gas. This heats the water in the furnace shell 2, causing it to vaporize. Then, the steam valve 18 is opened, and the vaporized steam is discharged through the steam valve 18, completing the output. After passing through the outer flue pipe 31, the flue gas enters the right smoke box 12. When ash removal is required, the covers 13 on both sides are opened to directly clean the interior of the left smoke box 11 and the right smoke box 12. The bolts of the burner 15 are removed, and the external scraper is inserted into the furnace shell 2 through the connecting pipe 14 to scrape the inner wall and remove the accumulated ash. The accumulated ash then slides out of the furnace shell 2. When the inner flue pipe 6 or the outer flue pipe 31 needs to be cleaned, the bolts of the corresponding mounting ring 7 are removed, and the inner flue pipe 6 or the outer flue pipe 31 is pulled out, cleaned, replaced, and then inserted back into its original position. With the assistance of the inner support plate 8 and the support frame 9, it is guided until it hits the retaining ring 10, and then fixed.

[0029] The left smoke box 11 and right smoke box 12 are not only important channels for flue gas flow, but also serve to collect and temporarily store dust in the flue gas. When cleaning is required, simply opening the cover 13 allows direct access to the dust and ash inside the left smoke box 11 and right smoke box 12. This openable design not only facilitates regular cleaning by operators but also reduces the risk of dust leakage during cleaning, improving cleaning efficiency and safety. The bolted connection allows for easy disassembly and assembly of the burner 15. After disassembling the burner 15, operators can use external scraper tools. The ash is directly cleaned from the inner wall of the furnace 2 by extending into the furnace 2 through the connecting pipe 14. The ash adhering to the inner wall is completely removed. Since the furnace 2 is set at an angle, the scraped ash will slide down naturally along the angle of the furnace 2 and finally be discharged from the other end of the furnace 2. This angled design not only facilitates the discharge of ash, but also avoids the accumulation of ash inside the furnace 2, thereby reducing the difficulty and workload of cleaning. This design makes the equipment easy to clean, reduces the difficulty of equipment maintenance, reduces maintenance time and cost, and improves the operating efficiency and service life of the equipment.

[0030] The inner smoke pipe 6 and the outer smoke pipe 31 are connected to the inner seat 4 and the outer seat 5 respectively via mounting rings 7. This not only ensures the stability of the inner smoke pipe 6 and the outer smoke pipe 31 during operation, but also greatly simplifies the disassembly and assembly process. Operators can remove the smoke pipes from the inner seat 4 or the outer seat 5 through the bolt-connected mounting rings 7, greatly reducing maintenance time and labor intensity. The support frame 9 is used to fix the outer smoke pipe 31, while the inner support plate 8 provides bottom support for the inner smoke pipe 6. Together, they constitute the sliding track limiting system of the smoke pipes, ensuring that the inner smoke pipe 6 and the outer smoke pipe 31 can slide stably along the predetermined track during installation. This allows operators to easily disassemble the inner smoke pipe 6 and the outer smoke pipe 31 for cleaning or replacement without large-scale disassembly of the entire equipment. This ability to quickly disassemble and maintain the equipment not only greatly improves the maintenance efficiency of the equipment, but also significantly extends the service life of the equipment.

[0031] Please see Figures 1-6A smoke exhaust pipe 23 is fixedly connected to one side of the right smoke box 12. A filter assembly is threadedly connected to the inner side of the other end of the smoke exhaust pipe 23. The filter assembly includes an outer threaded ring 25 bolted to the inner side of the smoke exhaust pipe 23 at the end away from the right smoke box 12. A connecting pipe 24 is fixedly connected to the inner side of the outer threaded ring 25. The outer side of the connecting pipe 24, near the right smoke box 12, is tightly fitted to the inner side of the smoke exhaust pipe 23. A sealing ring 26 is fixedly connected to the outer side of the connecting pipe 24 outside the smoke exhaust pipe 23. One side is tightly fitted, and the side of the connecting pipe 24 away from the flue pipe 23 is fixedly connected to the filter pipe 27. The filter element 28 is slidably connected to the inside of the filter pipe 27. The end of the filter pipe 27 away from the connecting pipe 24 is threadedly connected to the fixing cover 29, which abuts against the side of the filter element 28 away from the connecting pipe 24. The inside of the fixing cover 29 is fixedly connected to the activated carbon plate 30. The bottom end of the boiler outer liner 1 near the right smoke box 12 is fixedly connected to the drain valve 19, through which water inside the equipment can be discharged.

[0032] Then, the flue gas enters the exhaust pipe 23 from the right smoke box 12, passes through the connecting pipe 24, and enters the filter pipe 27. After being filtered and adsorbed by the filter element 28 and the activated carbon plate 30, it is discharged from the equipment. When it is necessary to clean or replace the filter element 28 and the activated carbon plate 30, rotate the filter pipe 27 to unscrew the outer threaded ring 25 from the exhaust pipe 23, then rotate the fixing cover 29 to unscrew it out of the filter pipe 27, and bring out the filter element 28. Clean or replace the filter element 28, the activated carbon plate 30 and the fixing cover 29, and then reinstall them in their original positions.

[0033] The filter element 28 effectively intercepts solid impurities such as dust and particulate matter in the flue gas, playing a filtering role. The activated carbon plate 30 further adsorbs and purifies harmful gases and odors in the flue gas, ensuring that the discharged flue gas meets environmental protection requirements. This dual filtration mechanism enables the boiler equipment to minimize its negative impact on the environment during operation. The external threaded ring 25 allows the filter tube 27 to be firmly installed at the end of the exhaust pipe 23. The sealing ring 26 is installed between the external threaded ring 25 and the exhaust pipe 23, ensuring the sealing between the filter tube 27 and the exhaust pipe 23. This design not only ensures the sealing of the flue gas during the filtration process and prevents flue gas leakage, but also makes the disassembly and assembly of the filter tube 27 extremely convenient. The fixing cover 29 can easily open and close the filter tube 27, making it easy for operators to replace or clean the internal filter element 28 and activated carbon plate 30. This detachable design greatly improves the ease of maintenance of the filter components, reduces maintenance costs and time, not only enhances the practicality of the equipment, but also ensures that the equipment can maintain a good filtration effect during long-term operation.

[0034] When water enters the boiler outer tank 1, it flows into the liquid level pipe 21 through the outflow pipe 20. Through the scale window on the inside of the liquid level pipe 21, the staff can intuitively observe the water level inside the boiler outer tank 1. This design allows the staff to clearly understand the water volume inside the equipment, so as to conveniently increase or decrease the water volume in a timely manner, ensure the normal operation of the boiler equipment, and improve the practicality and ease of operation of the equipment.

[0035] The working principle and usage process of this invention are as follows: A suitable amount of water is injected into the boiler outer liner 1 through the water inlet valve 17. The burner 15 is started, and fuel and air are blown into the furnace liner 2 for combustion. Heat is transferred from the furnace liner 2 to the external water, heating the water. Simultaneously, the high-temperature flue gas generated by combustion enters the transfer cylinder 3 from the furnace liner 2, then enters each inner smoke pipe 6, and then enters the left smoke box 11 from the other end of the inner smoke pipe 6. Finally, it enters the outer smoke pipe 31 from the left smoke box 11. The high-temperature flue gas circulates within the inner smoke pipe 6 and the outer smoke pipe 31. During flow, heat exchange occurs with the water inside the boiler outer liner 1, allowing the water to fully absorb the heat from the flue gas. This, combined with the heating of the water in the furnace liner 2, causes the water to vaporize. Then, the steam valve 18 is opened, and the vaporized steam is discharged through the steam valve 18, completing the output. After passing through the outer smoke pipe 31, the flue gas enters the right smoke box 12. Then, the flue gas enters the exhaust pipe 23 from the right smoke box 12, passes through the connecting pipe 24, and enters the filter pipe 27. After being filtered and adsorbed by the filter element 28 and the activated carbon plate 30, the flue gas is discharged from the equipment. When ash removal is required, open the covers 13 on both sides and clean the inside of the left smoke box 11 and the right smoke box 12 directly. Remove the bolts from the burner 15, pass the external scraper through the connecting pipe 14 and insert it into the furnace 2 to scrape the inner wall and remove the accumulated ash. The accumulated ash then slides out of the furnace 2. When it is necessary to clean the inner smoke pipe 6 or the outer smoke pipe 31, remove the bolts from the corresponding mounting ring 7, pull out the inner smoke pipe 6 or the outer smoke pipe 31, clean and replace it, and then insert it back into its original position. With the assistance of the inner support plate 8 and the support frame 9, guide it until it hits the retaining ring 10 and then complete the fixing. When it is necessary to clean and replace the filter element 28 and activated carbon plate 30, rotate the filter tube 27 to unscrew the outer screw ring 25 from the exhaust pipe 23, then rotate the fixing cover 29 to unscrew it out of the filter tube 27, and bring out the filter element 28. Clean or replace the filter element 28, activated carbon plate 30 and fixing cover 29, and then reinstall them in their original positions.

[0036] In the above scheme, it should be noted that: the burner 15, water inlet valve 17, steam valve 18 and drain valve 19 in this application are all existing products, and their specific structures, electrical connection methods (circuit layout) and working principles are all existing publicly disclosed technical means, which will not be described in detail here. It should also be noted that: existing controllers (or controller systems) can also be used in this application, and the electrical connection method, circuit layout method and control principle between the controller (or controller system) and the electrical components (burner 15) of this application are all existing disclosed technical means. At the same time, the controller (or controller system) can adopt conventional and mature existing products in the field, thereby realizing coordinated control of the electrical components of this application. Furthermore, the technical solution of this application does not involve the improvement of computer programs. Therefore, the specific control method between the controller (or controller system) and the electrical components of this application will not be described in detail here.
