Description

Technical Field

[0001] This utility model relates to the technical field of environmental protection cleaning equipment for boilers used in power plants, and in particular to an environmental protection device for boilers used in power plants. Background Technology

[0002] During long-term operation, power plant boilers are prone to accumulating scale, soot, and other harmful pollutants inside. These substances not only reduce the boiler's heat exchange efficiency and increase energy consumption, but may also cause internal corrosion, shorten the boiler's service life, and even lead to excessive emissions. Therefore, it is necessary to regularly clean and maintain the boiler's interior using specialized environmentally friendly cleaning equipment.

[0003] Currently, existing boiler cleaning devices generally suffer from unreasonable structural design and insufficient functional optimization, making it difficult to meet the demand for efficient and stable cleaning.

[0004] Firstly, the compatibility between the cleaning fluid delivery system and the rotating cleaning components is poor. Most devices do not adopt the structure of vertically connected second pipe and horizontal first pipe, which makes it impossible to accurately and efficiently deliver the cleaning fluid to the inlet structure of the rotating components. This often results in unstable fluid supply flow or delivery interruption, affecting the continuity of cleaning. Secondly, the core rotating cleaning component has design flaws. Some units lack cleaning holes spaced along the length of the outer wall of the rotating tube within the cleaning area, resulting in uneven cleaning coverage and difficulty in effectively cleaning certain areas inside the boiler. Furthermore, some units fail to seal the ends of the rotating tube furthest from the fixed pipeline, causing leakage of cleaning fluid during transport. This reduces cleaning pressure and wastes liquid, failing to meet environmental and energy-saving requirements. These defects collectively lead to low cleaning efficiency and incomplete cleaning in existing units, increasing operation and maintenance costs and failing to fully meet the actual needs of power plant boilers for environmentally friendly and efficient operation. Utility Model Content

[0005] In view of this, the technical problem to be solved by this utility model is: how to provide an environmental protection device for boilers in power plants to achieve efficient and stable cleaning of boilers.

[0006] To achieve the above objectives, this utility model proposes an environmental protection device for boilers used in power plants, which includes a support, a motor, a rotating pipe, and a conveying pipeline. The motor and the conveying pipe are respectively fixedly mounted on the support. The output end of the motor is connected to one end of the rotating pipe, and the rotating pipe is driven to rotate by the motor. The conveying pipeline includes a first pipeline and a second pipeline connected in a continuous manner, wherein the second pipeline is arranged in a vertical direction and the axis of the second pipeline is perpendicular to the axis of the first pipeline. The transfer pipe is located inside the first pipe and passes through the end plates located at both ends of the first pipe; the second pipe is used to deliver cleaning fluid into the delivery pipe. The portion of the rotating tube located inside the first pipe is provided with a liquid inlet groove, and multiple liquid inlet grooves are spaced apart along the circumference of the rotating tube, with the liquid inlet grooves communicating with the interior of the rotating tube; The inlet tank is located below and corresponds to the second pipe. The cleaning fluid transported through the second pipe enters the interior of the rotating pipe through the inlet tank. A cleaning hole is provided on the outer wall of the portion of the rotating pipe located outside the first pipe. The cleaning fluid flows through the inside of the rotating pipe and is transported outward through the cleaning hole under the rotation drive of the motor, so as to achieve cleaning of the inside of the boiler.

[0007] Furthermore, the plurality of cleaning holes are spaced apart along the length of the rotating tube.

[0008] Furthermore, a sealing plate is provided at the end of the rotating pipe away from the first pipe.

[0009] Furthermore, the liquid inlet tank extends along the axial direction of the first pipe.

[0010] Compared with related technologies, the environmental protection device for boilers in power plants proposed in this utility model has the following advantages: This technical solution achieves several superior technical effects. Firstly, the fixed installation of the motor and delivery pipeline via supports effectively ensures the stability of the entire device structure, preventing component shaking during motor-driven rotation and cleaning fluid delivery from affecting operation and providing a stable foundation for subsequent cleaning operations. The motor-driven rotation design, combined with the structure of the rotating pipe passing through the end plates at both ends of the first pipeline, allows the rotating pipe to rotate stably in the preset working position, providing power support for the dynamic spraying of the cleaning fluid.

[0011] The delivery pipeline adopts a structure in which a first pipeline connects to a vertically positioned second pipeline with its axis perpendicular to the first. The second pipeline corresponds to the inlet groove on the rotating pipe, allowing the cleaning fluid to be precisely guided into the inlet groove and into the rotating pipe. This ensures a smooth delivery path for the cleaning fluid, avoids interruptions, and guarantees a continuous and stable supply. The inlet grooves, spaced apart along the circumference of the rotating pipe, combined with the design of the inlet grooves extending along the axis of the first pipeline, significantly increase the effective area for the cleaning fluid to enter the rotating pipe, improving the inlet efficiency and allowing the cleaning fluid to quickly and fully fill the interior of the rotating pipe, avoiding insufficient supply problems.

[0012] The portion of the rotating pipe located outside the first pipe has cleaning holes spaced along its length. When the rotating pipe is driven by the motor to rotate, the cleaning fluid can be sprayed evenly from each cleaning hole. This achieves comprehensive circumferential coverage of the cleaning area through rotation, and expands the cleaning coverage length through the cleaning holes along the length, ensuring that all areas inside the boiler can be effectively cleaned and solving the problem of incomplete local cleaning.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] Please see Figure 1 - Figure 3 As shown, this utility model proposes an environmental protection device for boilers used in power plants, which includes a support 11, a motor 12, a rotating pipe 13, and a conveying pipe 14.

[0016] The motor 12 and the conveying pipe 14 are respectively fixed on the support 11. The output end of the motor 12 is connected to one end of the rotating pipe 13, and the rotating pipe 13 is driven by the motor 12 to rotate.

[0017] The conveying pipeline 14 includes a first pipeline 141 and a second pipeline 142 connected in a continuous manner. The second pipeline 142 is arranged in a vertical direction and its axis is perpendicular to the axis of the first pipeline 141.

[0018] The transfer pipe 13 is located inside the first pipe 141 and passes through the end plates located at both ends of the first pipe 141. The second pipe 142 is used to transport cleaning fluid into the interior of the delivery pipe 14.

[0019] The motor 12 and the conveying pipe 14 are fixedly mounted on the support 11 to prevent the vibration generated by the motor 12 during operation and the force brought by the flow of cleaning fluid in the conveying pipe 14 from causing component displacement or shaking, ensuring the connection stability between the motor 12 and the rotating pipe 13, thereby ensuring the smooth rotation of the rotating pipe 13, while maintaining the structural integrity of the conveying pipe 14, creating conditions for the smooth delivery of cleaning fluid.

[0020] The output end of the motor 12 is connected to the rotating tube 13 and drives it to rotate. The purpose is to provide power to the rotating tube 13 so that the rotating tube 13 can drive the cleaning hole 132 to rotate, thereby achieving cleaning of different positions inside the boiler.

[0021] The delivery pipe 14 adopts a structure in which the first pipe 141 and the second pipe 142 are connected. The second pipe 142 is set in a vertical direction and is perpendicular to the axis of the first pipe 141. The vertical setting of the second pipe 142 facilitates the cleaning fluid to enter the delivery pipe 14 quickly and accurately under the action of gravity or external force. At the same time, the vertical axis design allows the direction of the cleaning fluid delivery to be matched with the arrangement direction of the rotating pipe 13 in the first pipe 141, ensuring that the cleaning fluid can be efficiently guided to the liquid inlet structure of the rotating pipe 13.

[0022] The rotating pipe 13 is located inside the first pipe 141 and has end plates at both ends. This serves two purposes: firstly, to position and support the rotating pipe 13 and ensure its coaxiality during rotation; secondly, to protect the rotating pipe 13 from direct contact with pollutants inside the boiler and prevent damage; and thirdly, to facilitate the delivery of cleaning fluid to the rotating pipe 13 through the cooperation of the first pipe 141 and the second pipe 142.

[0023] The portion of the rotating pipe 13 located inside the first pipe 141 is provided with a liquid inlet trough 131. Multiple liquid inlet troughs 131 are spaced apart along the circumferential direction of the rotating pipe 13. The liquid inlet troughs 131 are connected to the interior of the rotating pipe 13 and extend along the axial direction of the first pipe 141.

[0024] An inlet tank 131 is provided in the portion of the rotating pipe 13 located inside the first pipe 141, and the inlet tank 131 is connected to the inside of the rotating pipe 13, providing an effective channel for the cleaning fluid transported by the second pipe 142 to enter the inside of the rotating pipe 13, ensuring that the cleaning fluid can be smoothly introduced into the rotating pipe 13, laying the foundation for subsequent spraying and cleaning of the boiler through the cleaning hole 132.

[0025] Multiple liquid inlet tanks 131 are spaced apart along the circumference of the rotating tube 13, which can form multiple liquid inlet points on the circumference of the rotating tube 13. This avoids the problem of uneven liquid inlet caused by a single liquid inlet point, ensures the uniformity of the cleaning fluid filling inside the rotating tube 13, and prevents the cleaning effect from being affected by local lack of liquid.

[0026] The liquid inlet tank 131 extends along the axis of the first pipe 141, which can significantly increase the contact area between the liquid inlet tank 131 and the cleaning liquid, increase the liquid inlet volume per unit time, solve the problem of low liquid inlet efficiency and untimely liquid supply caused by the small contact area of ​​the traditional liquid inlet structure, and further ensure that the cleaning liquid continuously and stably enters the interior of the rotating pipe 13.

[0027] By using the specific arrangement of the liquid inlet tank 131, the number of liquid inlet points, contact area and conveying requirements are precisely matched to form a mutually complementary liquid inlet optimization structure, which effectively solves the key problems in the liquid inlet process in the prior art and achieves simultaneous improvement in liquid inlet efficiency and uniformity. This combination of technologies is not a conventional choice for those skilled in the art and has outstanding substantive features and significant progress.

[0028] The liquid inlet tank 131 is located below and corresponds to the second pipe 142. The cleaning fluid transported through the second pipe 142 enters the interior of the rotating pipe 13 through the liquid inlet tank 131. A sealing plate is provided on the end of the rotating pipe 13 away from the first pipe 141.

[0029] The inlet tank 131 is positioned below and corresponding to the second pipe 142, so that the cleaning fluid transported by the second pipe 142 can directly and accurately enter the inlet tank 131 with the assistance of gravity. This avoids the cleaning fluid from deviating from the inlet channel and causing loss or failure to be effectively introduced into the rotating pipe 13, ensuring that the cleaning fluid enters the rotating pipe 13 efficiently and stably, providing a continuous and sufficient liquid source support for the subsequent spraying of cleaning fluid through the cleaning hole 132.

[0030] A sealing plate is provided at the end of the rotating pipe 13 away from the first pipe 141 to seal the end of the rotating pipe 13, preventing the cleaning fluid inside the rotating pipe 13 from leaking from the end, thereby maintaining the pressure stability of the cleaning fluid inside the rotating pipe 13, ensuring that the cleaning fluid can be sprayed out from the cleaning hole 132 with sufficient pressure, ensuring that the cleaning force meets the cleaning requirements inside the boiler, and avoiding waste of cleaning fluid.

[0031] By precisely aligning the liquid inlet tank 131 with the second pipe 142, and combining the sealing design of the end sealing plate of the rotating pipe 13, a mutually synergistic technical structure is formed, simultaneously solving the key defects of insufficient liquid inlet accuracy and leakage of the rotating pipe 13. This technical combination is not a conventional design choice for those skilled in the art, and significantly improves the liquid supply efficiency and cleaning stability of the device, with outstanding substantive features and significant progress.

[0032] A cleaning hole 132 is provided on the outer wall of the portion of the rotating pipe 13 located outside the first pipe 141. Multiple cleaning holes 132 are spaced apart along the length of the rotating pipe 13. The cleaning fluid flows through the interior of the rotating pipe 13 and is transported outward through the cleaning hole 132 under the rotation drive of the motor 12, so as to achieve cleaning of the inside of the boiler.

[0033] A cleaning hole 132 is provided on the outer wall of the portion of the rotating pipe 13 located outside the first pipe 141, providing a direct channel for the cleaning fluid inside the rotating pipe 13 to be sprayed outward, so that the cleaning fluid can be accurately applied to the area to be cleaned inside the boiler, thus establishing a core execution path for the cleaning operation.

[0034] Multiple cleaning holes 132 are spaced apart along the length of the rotating pipe 13, which can effectively broaden the spray coverage of the cleaning fluid along the length of the rotating pipe 13, avoid cleaning blind spots inside the boiler along the length of the rotating pipe 13 due to the excessive concentration of the cleaning holes 132, and ensure that pollutants at different lengths can be acted upon by the cleaning fluid.

[0035] The cleaning fluid flows inside the rotating pipe 13 and is delivered outward through the cleaning hole 132 under the rotation drive of the motor 12. With the help of the rotation of the rotating pipe 13, the spray direction of the cleaning hole 132 can be made to form a circumferential coverage as the rotating pipe 13 rotates. Combined with the interval arrangement in the length direction, it can achieve all-round cleaning of the boiler inside in both the circumferential and length directions.

[0036] After the motor 12 starts running, the output end of the motor 12 drives the rotating tube 13 connected to it to rotate. Since the rotating tube 13 passes through the end plates at both ends of the first pipe 141, the rotating tube 13 can rotate stably inside the first pipe 141 and in the area extending to the outside.

[0037] Subsequently, the cleaning fluid is transported through the delivery pipe 14, wherein the second pipe 142 is arranged vertically and its axis is perpendicular to the first pipe 141, which can accurately guide the cleaning fluid into the first pipe 141; since the liquid inlet trough 131 is located below and corresponding to the second pipe 142, and the liquid inlet trough 131 extends along the axis of the first pipe 141 and is spaced along the circumference of the rotating pipe 13, the cleaning fluid can smoothly enter the rotating pipe 13, and the design of multiple liquid inlet troughs 131 can ensure the efficiency and uniformity of liquid inlet, and avoid liquid shortage in the rotating pipe 13.

[0038] When the cleaning fluid is injected, the motor 12 can be driven to run at a low speed or stop to ensure that the cleaning fluid can enter the interior of the rotating pipe 13 through the inlet tank 131.

[0039] The end of the rotating pipe 13 away from the first pipe 141 is provided with a sealing plate to prevent the cleaning fluid from leaking from the end of the rotating pipe 13 and to maintain a certain pressure inside the rotating pipe 13. When the cleaning fluid flows inside the rotating pipe 13 to the part located outside the first pipe 141, under the action of the rotating pipe 13 driven by the motor 12 to rotate, the cleaning fluid is sprayed outward from the cleaning holes 132 arranged at intervals along the length of the outer wall of the rotating pipe 13. The rotational motion, combined with the interval distribution of the cleaning holes 132, can make the cleaning fluid fully cover the area inside the boiler to be cleaned, and finally achieve effective cleaning of the boiler.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
