Description

Technical Field

[0001] This utility model relates to the field of steam generator technology, specifically to a multi-stage cooling boiler structure suitable for steam generation. Background Technology

[0002] A steam generator is a device that heats water and converts it into steam. It is also known as a steam boiler. The steam generator uses the heat generated by burning fuel or using other energy sources such as electricity to transfer the heat to the water in the furnace, so that the water temperature rises continuously until it reaches the boiling point and vaporizes, eventually producing steam.

[0003] Many existing boiler cooling systems use annular cooling tank structures, which typically involve welding or mounting an integral annular water-cooled jacket around the boiler body. Heat is absorbed through internal circulating water. When the pipes become blocked, corroded, or leak, the entire annular structure needs to be dismantled to repair the internal pipes, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-stage cooling boiler structure suitable for steam generation, in order to solve the problem mentioned in the background art that most existing boiler cooling systems adopt annular cooling tank structures. Typically, an integral annular water-cooled jacket is welded or fitted around the boiler body, and heat is absorbed by internal circulating water. When the pipes are blocked, corroded, or leaking, the entire annular structure needs to be removed to repair the internal pipes, which is time-consuming and labor-intensive.

[0005] To solve the above problems, this utility model provides the following technical solution: a multi-stage cooling boiler structure suitable for steam generation, comprising a steam boiler and a cooling section:

[0006] The cooling section is located on the outside of the steam boiler. The cooling section has a connecting frame nested on the outside of the steam boiler. Several cooling boxes are embedded inside the connecting frame. The inner side of several cooling boxes abuts against the side wall of the steam boiler. Cooling pipes are installed inside several cooling boxes. Several double-ended pipes are provided on the side of the connecting frame. The double-ended pipes are connected to the cooling pipes by bolted detachable flanges.

[0007] In some existing boilers, the external cooling system design typically involves fixing the cooling pipes or cooling sleeves as a whole to the outside of the boiler body to achieve the function of absorbing boiler heat through circulating coolant. However, this integrated structure is prone to requiring shutdown due to corrosion, blockage, or leakage of the cooling pipes during use. Furthermore, due to the limitations of the overall structure, it is often difficult to disassemble and replace individual pipes, resulting in inconvenient maintenance, low inspection efficiency, and high maintenance costs.

[0008] This cooling section adopts a detachable modular design, allowing for flexible connection and disassembly of cooling pipes. This facilitates the installation, replacement, or repair of local cooling pipes, significantly improving maintenance efficiency and reducing maintenance costs. Simultaneously, the sequential connection of cooling pipes and connecting pipes forms a continuous cooling circuit, enabling the coolant to fully absorb boiler heat as it flows through multiple cooling units, thereby increasing the heat transfer area and cooling path.

[0009] By adopting the above technical solution, the cooling pipes can be flexibly connected and disassembled, facilitating the installation, replacement and maintenance of the cooling pipes, while ensuring the sealing of the connection, allowing the coolant to flow normally in the cooling pipes, and realizing the cooling function of the steam boiler.

[0010] Preferably, the connecting frame is detachably nested with the steam boiler by bolts, and the cooling box is detachably nested with the connecting frame by bolts.

[0011] By adopting the above technical solution, the connecting frame and cooling box can be easily installed and disassembled. When the steam boiler needs maintenance or parts replacement, the connecting frame can be easily removed from the steam boiler. When the cooling box malfunctions or needs cleaning, it can also be easily removed from the connecting frame, reducing maintenance costs and difficulty.

[0012] Preferably, the cooling section also has a connecting cavity formed inside the connecting frame, and the cooling box is embedded in the connecting cavity and connected to the connecting frame.

[0013] By adopting the above technical solution, the installation of the cooling box in the connecting frame can be more stable. The connecting cavity provides a precise installation position for the cooling box, ensuring a tight fit between the cooling box and the side wall of the steam boiler. This facilitates the transfer of heat from the steam boiler to the cooling pipes inside the cooling box, thereby improving cooling efficiency.

[0014] Preferably, the connecting cavity has six openings, and the six connecting cavities are arranged in a central rotational symmetry structure around the center of the connecting frame.

[0015] By adopting the above technical solution, the cooling boxes can be evenly distributed around the steam boiler, thereby achieving uniform cooling of the steam boiler. This avoids localized overheating of the steam boiler, ensures the overall performance stability of the steam boiler, and extends its service life.

[0016] Preferably, there are six cooling pipes and five docking double-ended pipes, with the six cooling pipes connected together by the first and last ends of the five docking double-ended pipes.

[0017] By adopting the above technical solution, a continuous cooling channel can be formed, and the coolant can flow through six cooling pipes in sequence, which increases the contact area and cooling path between the coolant and the steam boiler, thereby improving the cooling effect.

[0018] Preferably, the cooling section also has a liquid inlet pipe disposed on the side of the connecting frame, and the liquid inlet pipe and the liquid return pipe are respectively connected to the two ends of the cooling pipe connected to the first end.

[0019] By adopting the above technical solution, a complete coolant circulation system can be constructed. The coolant enters the cooling pipe from the inlet pipe, absorbs heat from the steam boiler in the cooling pipe, and then flows out through the return pipe, realizing the recycling of the coolant.

[0020] Preferably, the cooling pipe is S-shaped, with both ends extending to the outside of the cooling box.

[0021] By adopting the above technical solution, the contact area between the cooling pipe and the coolant in the cooling tank can be increased, allowing the coolant to absorb the heat transferred by the cooling pipe more fully and improving the cooling efficiency.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: by providing a cooling section, the cooling pipes can be flexibly connected and disassembled, facilitating the installation, replacement and maintenance of the cooling pipes, while ensuring the sealing of the connection, allowing the coolant to flow normally in the cooling pipes, and realizing the cooling function of the steam boiler; the six cooling pipes are connected together by five double-ended pipes to form a continuous cooling channel, and the coolant can flow through the six cooling pipes in sequence, increasing the contact area and cooling path between the coolant and the steam boiler, and improving the cooling effect.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a multi-stage cooling boiler structure suitable for steam generation, including a steam boiler 1 and a cooling section 2.

[0033] The steam boiler 1 is made of high-quality steel, which has good high temperature and pressure resistance. It is equipped with heating devices such as burners and electric heating tubes, which can efficiently transfer energy to the water in the boiler. The above is the prior art and will not be described in detail below. The cooling section 2 is located on the outside of the steam boiler 1. The cooling section 2 has a connecting frame 201 nested on the outside of the steam boiler 1. Several cooling boxes 206 are embedded inside the connecting frame 201. The inner side of the cooling boxes 206 abuts against the side wall of the steam boiler 1. Cooling pipes 207 are installed inside the cooling boxes 206. Several double-ended pipes 203 are provided on the side of the connecting frame 201. The double-ended pipes 203 are connected to the cooling pipes 207 by bolted detachable flanges, which can flexibly connect and disconnect the cooling pipes 207, making it convenient to install, replace and maintain the cooling pipes 207. At the same time, it ensures the sealing of the connection, allowing the coolant to flow normally in the cooling pipes 207, so as to realize the cooling function of the steam boiler 1.

[0034] Example 2

[0035] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a multi-stage cooling boiler structure suitable for steam generation, including a cooling section 2.

[0036] The connecting frame 201 is detachably nested to the steam boiler 1 via bolts, and the cooling box 206 is also detachably nested to the connecting frame 201 via bolts, allowing for easy installation and removal of both the connecting frame 201 and the cooling box 206. When the steam boiler 1 requires maintenance or parts replacement, the connecting frame 201 can be easily removed from the steam boiler 1. Similarly, when the cooling box 206 malfunctions or requires cleaning, it can be conveniently removed from the connecting frame 201, reducing maintenance costs and complexity.

[0037] A connecting cavity 202 is provided inside the connecting frame 201. The cooling box 206 is embedded in the connecting cavity 202 and connected to the connecting frame 201. This makes the installation of the cooling box 206 in the connecting frame 201 more stable. The connecting cavity 202 provides a precise installation position for the cooling box 206, ensuring a tight contact between the cooling box 206 and the side wall of the steam boiler 1. This facilitates the transfer of heat from the steam boiler 1 to the cooling pipe 207 inside the cooling box 206, thereby improving cooling efficiency.

[0038] The connecting chambers 202 are provided in six parts, and the six connecting chambers 202 are arranged in a central rotational symmetry structure around the center of the connecting frame 201. This allows the cooling boxes 206 to be evenly distributed around the steam boiler 1, thereby achieving uniform cooling of the steam boiler 1. This avoids local overheating of the steam boiler 1, ensures the overall performance stability of the steam boiler 1, and extends the service life of the steam boiler 1.

[0039] There are six cooling pipes 207 and five docking double-ended pipes 203. The six cooling pipes 207 are connected together by the first and last ends of the five docking double-ended pipes 203 to form a continuous cooling channel. The coolant can flow through the six cooling pipes 207 in sequence, which increases the contact area and cooling path between the coolant and the steam boiler 1 and improves the cooling effect.

[0040] A liquid inlet pipe 204 is provided on the side of the connecting frame 201. The liquid inlet pipe 204 and the liquid return pipe 205 are respectively connected to the two ends of the cooling pipe 207 connected to the first end, thus constructing a complete coolant circulation system. The coolant enters the cooling pipe 207 from the liquid inlet pipe 204, absorbs heat from the steam boiler 1 in the cooling pipe 207, and then flows out through the liquid return pipe 205, realizing the recycling of the coolant.

[0041] The cooling pipe 207 is S-shaped, with both ends extending to the outside of the cooling tank 206. This increases the contact area between the cooling pipe 207 and the coolant inside the cooling tank 206, allowing the coolant to absorb the heat transferred by the cooling pipe 207 more fully and improving cooling efficiency.

[0042] Working Principle: First, the heating device inside the steam boiler 1 is activated to heat the water inside the boiler, gradually increasing its temperature and converting it into steam to meet the steam generation requirements. Simultaneously, coolant enters through the inlet pipe 204 into a continuous cooling channel formed by six cooling pipes 207 connected end-to-end by five double-ended pipes 203. Since the cooling pipes 207 are S-shaped and located inside the cooling box 206, and the inner side of the cooling box 206 is in close contact with the side wall of the steam boiler 1, the heat generated by the steam boiler 1 is transferred to the cooling pipes 207 within the cooling box 206. During the flow, the coolant, due to its large contact area with the cooling pipes 207, can fully absorb the heat transferred by the cooling pipes 207, thereby cooling the steam boiler 1. Because the six connecting cavities 202 are centrally rotationally symmetrical around the center of the connecting frame 201, the cooling box 206 is evenly distributed around the steam boiler 1, ensuring efficient cooling of the steam boiler 1. Uniform cooling is achieved, preventing localized overheating. The coolant, having absorbed heat, continues to flow in the cooling channel and eventually flows out through the return pipe 205. The outflowing coolant can undergo external cooling treatment to lower its temperature before re-entering the inlet pipe 204, thus achieving coolant recycling. This ensures the continuity and stability of the cooling process, enabling the steam boiler 1 to operate continuously and stably, efficiently generating steam. When the steam boiler 1 needs maintenance or component replacement, the connecting frame 201 can be easily removed from the steam boiler 1 by unscrewing the bolts between it and the steam boiler 1. Similarly, if the cooling box 206 malfunctions or needs cleaning, the bolts between the cooling box 206 and the connecting frame 201 can be easily removed, detaching the cooling box 206 from the connecting frame 201, reducing maintenance costs and difficulty.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
