Description

Technical Field

[0001] The utility model relates to the technical field of water-cooled walls, in particular to a high-strength membrane-type water-cooled wall for boilers. Background Art

[0002] The water-cooled wall is an important component inside the boiler, used to absorb and transfer the heat generated by the combustion area to protect the structure of the boiler and ensure its normal operation. The water-cooled wall is usually installed on the boiler furnace wall, surrounding the combustion area, and plays a cooling role.

[0003] The existing water-cooled wall cannot provide heat-resistant and corrosion-resistant protection to the water-cooled wall tubes during use, thereby reducing the service life of the water-cooled wall tubes and causing damage to the water-cooled wall tubes, resulting in a waste of resources.

[0004] The existing patent (Announcement No.: CN220551935U) is a water-cooled wall for a boiler, which is provided with an anti-wear layer, a refractory layer, an anti-corrosion layer and a water outlet. The wear-resistant layer provided on the outer wall surface of the water-cooled wall tube can play a role in wear protection for the outer wall surface of the water-cooled wall tube, preventing the water-cooled wall tube from causing serious wear of the outer wall under long-term use, thereby reducing the heat resistance of the water-cooled wall tube. In addition, due to the provision of the refractory layer, some cobalt can be added to the inside of the steel during the manufacturing of the water-cooled wall tube, so that when the water-cooled wall tube is formed, the high temperature resistance effect of the outer wall is more ideal, and the service life of the water-cooled wall tube is increased. The main function of the anti-corrosion layer is to provide anti-corrosion protection for the inside of the water-cooled wall tube, preventing the inside of the water-cooled wall tube from being immersed in water for a long time, which is easy to cause internal rust and corrosion.

[0005] In view of the above problems, the existing patent provides a solution. During use, the inner wall of the water-cooled wall tube cannot maintain uniform contact with the water flow, which greatly reduces the heat absorption efficiency. At the same time, when the water-cooled wall tube is in use, a large amount of water will continuously impact its inner wall, and the lack of certain support will cause the water-cooled wall tube to deform.

[0006] Therefore, a high-strength membrane water-cooled wall for boiler is proposed. Utility Model Content

The receiving groove 401 is opened inside a plurality of protective plates 301, the placement frame 402 is fixedly connected to the top of the extension pipe 204, the water injection pipe 403 is fixedly connected to one side of the placement frame 402, and a plurality of transmission pipes 404 are all fixedly connected to the bottom of the placement frame 402.

[0035] Specifically, Figure 1 As shown, one side of the plurality of protection plates 301 is fixedly connected with an extension block 5 , the number of the extension blocks 5 is several and evenly distributed, and one side of the extension block 5 is fixedly connected with a reinforcement block 6 .

[0036] Specifically, Figure 1 As shown, a mounting plate 7 is fixedly connected to one side of the extension block 5 , a second threaded hole 8 is provided inside the mounting plate 7 , and a second threaded column 9 is threadedly connected to the second threaded hole 8 .

[0039] Specifically, Figure 2 As shown, the inner wall of the placement frame 402 is provided with an anti-scaling layer 15 , and the material of the anti-scaling layer 15 is polyurethane. The anti-scaling layer 15 is used to prevent scale from forming on the inner wall of the placement frame 402 and clogging the extension pipe 204 .

[0040] When in use, multiple protective plates 301 are placed on both sides of the water-cooled wall tube body 1 respectively, and then the first threaded column 303 is screwed into the first threaded hole 302, so that the multiple protective plates 301 clamp the water-cooled wall tube body 1, and the outer wall of the water-cooled wall tube body 1 is shielded and protected to prevent it from being damaged by external force when in use.

The support rod 13 is used in conjunction with the baffle 14 to prevent external debris from falling on the cover plate 12 and affecting the exhaust. The anti-scaling layer 15 can prevent the inner wall of the placement frame 402 from scaling and clogging the extension pipe 204.

[0041] By adopting the above technical solution, the problem of an existing boiler water-cooled wall being unable to keep the inner wall of the water-cooled wall tube in uniform contact with the water flow during use is solved, which greatly reduces the heat absorption efficiency. At the same time, when the water-cooled wall tube is in use, a large amount of water will continuously impact the inner wall thereof, and the lack of certain support will cause the water-cooled wall tube to deform is solved.

[0042] Working principle: When the present application is in use, a plurality of protective plates 301 are respectively placed on both sides of the water-cooled wall tube body 1, and then the first threaded column 303 is screwed into the first threaded hole 302, so that the plurality of protective plates 301 clamp the water-cooled wall tube body 1, and shield and protect the outer wall of the water-cooled wall tube body 1 to prevent it from being damaged by external force during use. The extension block 5 is used in conjunction with the reinforcement block 6 to provide support for the mounting plate 7. When in use, the mounting plate 7 is placed in the installation position, and then the second threaded column 9 is screwed into the second threaded hole 8 to fix the water-cooled wall tube body 1. When the water-cooled wall tube body 1 is in use, water is injected into the placement frame 402 through the water injection pipe 403, so that a certain amount of water is always maintained inside the placement frame 402, and the water in the placement frame 402 enters the interior of the water-cooled wall tube body 1 through the extension pipe 204 and is guided by the spiral blades 201 The water flow is guided so that the water flow can evenly contact the inner wall of the water-cooled wall tube body 1 to improve the heat dissipation efficiency. The support column 202 can provide support for the spiral blade 201. At the same time, the reinforcing rod 203 is connected to the support column 202, which can provide support for the inner wall of the water-cooled wall tube body 1 to prevent it from being deformed. At the same time, the water in the placement frame 402 will enter the receiving groove 401 through the transmission pipe 404 to dissipate the heat of the outer wall of the water-cooled wall tube body 1 to prevent the water-cooled wall tube body 1 from being deformed. When the water flow contacts the high temperature, steam will be generated. The steam flowing upward will push the cover plate 12 to make it slide in the slide groove 11 and finally be discharged from the exhaust pipe 10. The support rod 13 is used in conjunction with the baffle 14 to prevent external debris from falling on the cover plate 12 and affecting the exhaust. The anti-scaling layer 15 can prevent the inner wall of the placement frame 402 from scaling and clogging the extension pipe 204.
