Description

Technical Field

[0001] This invention relates to the field of boiler technology, and more particularly to a boiler with high thermal insulation properties. Background Art

[0002] A boiler is an energy conversion device. The energy input into a boiler is the chemical energy of oil fuel or electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The hot water or steam produced in the boiler can directly provide the heat energy required for industrial production and people's lives. It can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator.

[0003] When using a boiler to heat water, poor insulation results in a large amount of heat loss, which not only wastes energy but may also cause thermal pollution to the surrounding environment. Therefore, most boilers adopt the method of extending the heat conduction path and reducing the heat dissipation per unit area to improve the insulation performance of the boiler. However, this method often results in a large boiler size, which is not conducive to installation and use. Summary of the Invention

[0034] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] This invention proposes a boiler with high thermal insulation properties, as detailed below. Figures 1 to 6 Please provide a detailed explanation.

[0036] A boiler with high thermal insulation includes a boiler body 1 and a multi-layer thermal insulation structure disposed on the outer periphery of the boiler body 1. The boiler includes a combustion chamber 13, and the multi-layer thermal insulation structure includes:

[0037] A high-temperature resistant layer 21 is disposed on the outer wall of the combustion chamber 13;

[0038] A buffer insulation layer 23 is disposed on the outer wall of the high temperature resistant layer 21;

[0039] The reflective layer 24 is disposed on the outer wall of the buffer insulation layer 23;

[0040] A moisture-proof layer 25 is disposed on the outer wall of the reflective layer 24;

[0041] The outer protective layer 26 is disposed on the outer wall of the moisture-proof layer 25.

[0042] This invention effectively improves thermal insulation performance and reduces heat loss by setting up a multi-layered thermal insulation structure, thus ensuring the safe operation of the boiler.

[0043] Optionally, the buffer insulation layer 23 is provided with a plurality of connecting posts 22, one end of the connecting post 22 is fixedly connected to the high temperature resistant layer 21, and the other end of the connecting post 22 is fixedly connected to the reflective layer 24.

[0044] The connection column 22 is designed to enhance the connection strength between the high-temperature resistant layer 21 and the reflective layer 24, and to prevent the relatively soft buffer insulation layer 23 between the high-temperature resistant layer 21 and the reflective layer 24 from being squeezed and deformed, so as to ensure that the overall structure of the insulation mechanism 2 is more stable, thereby improving the insulation performance and safety of the boiler. The connection column 22 can be made of a material compatible with the high-temperature resistant layer 21 and the reflective layer 24 to ensure that it has good high-temperature resistance and connection performance.

[0045] In some embodiments, when the boiler body 1 is running, the burner 14 ignites the fuel, transferring heat to the combustion chamber 13, thereby heating the boiler body 1. Each layer of the multi-layer insulation structure performs different insulation or protection functions, as follows:

[0046] The high-temperature resistant layer 21 is set as a high-sealing ceramic fiber material layer; as the first layer that directly contacts the outer wall of the boiler body 1, the high-temperature resistant layer 21 mainly functions to withstand high temperature and prevent heat from being directly transferred to the outer structure. The high-temperature resistant layer 21 is made of high-sealing ceramic fiber material, which has excellent high-temperature resistance and sealing performance and can effectively isolate high temperature and reduce heat loss.

[0047] The buffer insulation layer 23 is set as a lightweight mullite fiber blanket layer; the buffer insulation layer 23 is set on the outer wall of the high temperature resistant layer 21, and its main function is to further insulate heat. The buffer insulation layer 23 is made of lightweight mullite fiber blanket. This material has the characteristics of low density, low thermal conductivity and high temperature resistance, which can effectively improve the heat insulation performance of the boiler body 1.

[0048] The reflective layer 24 is set as an aluminum foil composite ceramic layer; the reflective layer 24 is set on the outer wall of the buffer insulation layer 23 and its main function is to reflect heat and reflect some of the heat back into the boiler body 1, thereby further improving the thermal efficiency. The reflective layer 24 is made of aluminum foil composite ceramic, which has excellent reflective performance and high temperature resistance, and can effectively reflect heat and reduce heat loss.

[0049] The moisture-proof layer 25 is set as an aluminum-plastic composite board layer; the moisture-proof layer 25 is set on the outer wall of the reflective layer 24, and its main function is to prevent external moisture from entering the interior of the boiler body 1 and to protect the internal heat insulation material from moisture. The moisture-proof layer 25 is made of aluminum-plastic composite board, which has excellent moisture-proof performance and corrosion resistance, and can effectively isolate moisture and protect the heat insulation performance of the boiler body 1.

[0050] The outer protective layer 26 is a stainless steel plate layer; the outer protective layer 26 is set on the outer wall of the moisture-proof layer 25 and its main function is to protect the internal heat insulation structure from external damage. The outer protective layer 26 is made of stainless steel plate, which has excellent corrosion resistance and mechanical strength, and can effectively protect the heat insulation structure of the boiler body 1 and extend its service life.

[0051] In some embodiments, a plurality of vent holes 27 are provided on the outer wall of the outer protective layer 26. The vent holes 27 allow a small amount of gas to escape, preventing excessive internal pressure from damaging the boiler body 1 and improving the safety performance of the boiler body 1.

[0052] In some embodiments, a mounting bracket 12 for supporting and fixing the boiler body 1 is provided on the outer periphery of the heat-insulating multilayer structure. At least two mounting brackets 12 are provided. A base 11 is fixedly connected below the mounting bracket 12. A burner 14 is provided at one end of the combustion chamber 13.

[0053] Specifically, the base 11 provides stable support for the boiler body 1, ensuring the stability of the boiler body 1 during operation. The fixing frame 12 not only supports the combustion chamber 13, but also fixes the overall structure of the boiler body 1, enhancing the stability of the boiler body 1. As the core component of the boiler body 1, the combustion chamber 13 undertakes the important tasks of fuel combustion and heat transfer. The burner 14 is responsible for igniting the fuel and providing a stable heat source for the combustion chamber 13.

[0054] In some embodiments, an air-cooling assembly 3 is provided between adjacent fixing frames 12. The air-cooling assembly 3 includes a mounting frame 31 disposed between adjacent fixing frames 12, and a cooling fan 32 is disposed on the side of the mounting frame 31 facing the heat-insulating multi-layer structure. When the boiler body 1 is running, the cooling fan 32 is activated simultaneously to generate airflow by rotation, which accelerates the airflow and removes excess heat from the surface of the boiler body 1, thereby effectively reducing the temperature of the outer shell of the boiler body 1 and indirectly reducing the dissipation of heat to the outside.

[0055] In one embodiment, a first bolt 33 is provided on the side of the cooling fan 32 facing the mounting bracket 31. The cooling fan 32 is fixedly connected to the mounting bracket 31 by the first bolt 33, so that the cooling fan 32 can be stably fixed on the mounting bracket 31. In subsequent maintenance and cleaning of the cooling fan 32, the staff can separate the cooling fan 32 and the mounting bracket 31 by removing the first bolt 33.

[0056] In some embodiments, a dustproof component 4 is provided on the side of the cooling fan 32 away from the heat insulation multilayer structure. The dustproof component 4 includes a mounting frame 41 disposed on the side of the cooling fan 32 away from the mounting bracket 31. An air duct is provided on the mounting frame 41 corresponding to the position of the cooling fan 32. A mounting groove 42 is provided around the air duct on the side of the mounting frame 41 facing the cooling fan 32. A dustproof net 43 is detachably disposed in the mounting groove 42. When the cooling fan 32 is working, the dustproof net 43 can effectively block external dust and debris from entering the cooling fan 32, preventing the cooling fan 32 from being blocked or damaged during operation, thereby ensuring the normal operation and heat dissipation effect of the cooling fan 32.

[0057] In one embodiment, a second bolt 44 is provided on the mounting frame 41. The second bolt 44 detachably and securely connects the mounting frame 41 to the cooling fan 32. On the one hand, the second bolt 44 can stably fix the dust filter 43 to the cooling fan 32, preventing the dust filter component 4 from loosening during the operation of the cooling fan 32. On the other hand, when the dust filter 43 needs to be disassembled, replaced, or cleaned, the operator can disassemble the mounting frame 41 and the dust filter 43 by removing the second bolt 44. After replacement, the mounting frame 41 and the dust filter 43 can be reinstalled by installing the second bolt 44. The disassembly and installation process is convenient and quick.

[0058] In some embodiments, the boiler body 1 is provided with a cooling assembly 5 for cooling the combustion chamber 13. The cooling assembly 5 includes a water storage tank 51 and a water pump 53 disposed on the base 11. A water inlet pipe 52 is provided between the water pump 53 and the water storage tank 51, and a water outlet pipe 54 is provided between the water pump 53 and the combustion chamber 13. A drain pipe 55 is provided on the combustion chamber 13. When cooling of the combustion chamber 13 is required, the relevant personnel start the water pump 53. The water pump 53 draws cooling water from the water storage tank 51 through the water inlet pipe 52 and delivers the cooling water to the boiler through the water outlet pipe 54 to cool the combustion chamber 13. The cooled water is discharged through the drain pipe 55, achieving effective cooling of the boiler and further improving the boiler's thermal efficiency and safety.

[0059] In some embodiments, a control cabinet 6 is provided on the base 11, which is electrically connected to the water pump 53, burner 14, cooling assembly 5, and air-cooled assembly 3. The control cabinet 6 serves as the control center of the boiler body 1, integrating various control functions of the boiler body 1, including but not limited to starting and stopping the burner 14, controlling the cooling fan 32, and adjusting the cooling assembly 5. Through the control cabinet 6, relevant personnel can conveniently monitor and operate the boiler body 1, ensuring its safe and stable operation. The control cabinet 6 can effectively monitor the operating status of the boiler body 1, promptly detect and handle abnormal situations, thereby greatly improving the safety and reliability of the boiler body 1.

[0060] Working principle: When the boiler body 1 is running, the burner 14 ignites the fuel and transfers heat to the combustion chamber 13, thereby heating the water or other media inside the boiler body 1. In order to improve the heat insulation effect of the boiler body 1, it includes a multi-layer structure, each layer of the structure undertaking different heat insulation and protection functions.

[0061] The high-temperature resistant layer 21, as the first layer that directly contacts the outer wall of the boiler body 1, mainly functions to withstand high temperatures and prevent heat from being directly transferred to the outer structure. The high-temperature resistant layer 21 is made of high-sealing ceramic fiber material, which has excellent high-temperature resistance and sealing performance and can effectively isolate high temperatures and reduce heat loss.

[0062] The buffer insulation layer 23 is set on the outer wall of the high temperature resistant layer 21. Its main function is to further insulate heat. The buffer insulation layer 23 is made of lightweight mullite fiber blanket. This material has the characteristics of low density, low thermal conductivity and high temperature resistance, which can effectively improve the heat insulation performance of the boiler body 1.

[0063] The reflective layer 24 is set on the outer wall of the buffer insulation layer 23. Its main function is to reflect heat and reflect some of the heat back into the boiler body 1, thereby further improving thermal efficiency. The reflective layer 24 is made of aluminum-filled composite ceramic. This material has excellent reflective performance and high temperature resistance, which can effectively reflect heat and reduce heat loss.

[0064] The moisture-proof layer 25 is set on the outer wall of the reflective layer 24. Its main function is to prevent external moisture from entering the boiler and protect the internal insulation material from moisture. The moisture-proof layer 25 is made of aluminum-plastic composite board, which has excellent moisture-proof performance and corrosion resistance. It can effectively isolate moisture and protect the insulation performance of the boiler body 1.

[0065] The outer protective layer 26 is set on the outer wall of the moisture-proof layer 25. Its main function is to protect the internal heat insulation structure from external damage. The outer protective layer 26 is made of stainless steel plate. This material has excellent corrosion resistance and mechanical strength, which can effectively protect the heat insulation structure of the boiler body 1 and extend its service life.

[0066] When the boiler body 1 is running, the cooling fan 32 is activated simultaneously. The fan rotates to generate airflow, which accelerates the airflow and carries away excess heat from the surface of the boiler body 1. This effectively reduces the temperature of the boiler body 1's outer shell and indirectly reduces heat loss to the outside.

[0067] When the cooling fan 32 is working, the dust filter 43 can effectively block external dust and debris from entering the cooling fan 32, preventing the cooling fan 32 from being blocked or damaged during operation, thus ensuring the normal operation and heat dissipation effect of the cooling fan 32.

[0068] When it is necessary to cool the inside of the combustion chamber 13, the relevant personnel start the water pump 53. The water pump 53 draws out the cooling water in the water storage tank 51 through the water inlet pipe 52 and delivers the cooling water to the boiler through the water outlet pipe 54 to cool the combustion chamber 13. The cooled water is discharged through the drain pipe 55, which realizes the effective cooling of the boiler body 1 and further improves the thermal efficiency and safety of the boiler body 1.
