Description

Technical Field

[0001] This utility model belongs to the field of sootblower technology, specifically relating to a positive pressure device for sootblower furnace wall holes. Background Technology

[0002] In the operation of industrial boilers, ash accumulation and slag buildup are common problems affecting thermal efficiency and safety. The IK545 sootblower provides a reliable solution to these problems. The IK545 sootblower boasts a compact and rationally designed structure. It employs an advanced drive system, providing powerful and stable operation, and precisely controls the extension, retraction, and rotation of the sootblowing tubes to ensure comprehensive and thorough cleaning of the boiler's heating surfaces. The sootblowing tubes are made of high-strength, high-temperature-resistant special alloy materials, maintaining excellent performance and stability even under harsh high-temperature and high-pressure conditions, significantly extending the equipment's service life. Its sootblowing effect is remarkable. Utilizing high-pressure steam or compressed air as the blowing medium, the sootblower generates a powerful impact force, quickly and effectively removing ash and slag from the boiler's heating surfaces, restoring their heat transfer performance, improving boiler thermal efficiency, and reducing energy consumption. Simultaneously, it reduces safety hazards such as localized overheating and tube rupture caused by ash and slag buildup, ensuring the safe and stable operation of the boiler.

[0003] When the sootblower is in operation, significant ash accumulation and leakage can occur near the furnace wall openings. Large amounts of ash will overflow from this area, causing serious pollution to surrounding equipment and facilities. This leaking ash, along with the accompanying flue gas, poses a significant threat to the sootblower's outer tube. Because the ash and flue gas may contain corrosive substances and particles with a certain degree of hardness, their continuous impact and adhesion to the outer tube surface will gradually lead to thinning and wear. As a crucial component of the sootblower, thinning of the outer tube due to wear reduces its structural strength and sealing performance. This not only affects the sootblower's normal blowing efficiency but also significantly increases the risk of equipment malfunction, seriously impacting the safe and stable operation of the sootblower and creating potential hazards for the normal operation of the entire boiler system. Utility Model Content

[0004] The purpose of this invention is to provide a positive pressure device for the furnace wall holes of a sootblower, to solve the problem mentioned in the background art: in industrial boiler operation systems, although the IK545 sootblower is a key device for ensuring the cleanliness of the heating surface, it previously suffered from the problem of a large amount of accumulated ash and flue gas leaking outward from the furnace wall holes. This not only had a serious negative impact on the cleanliness and hygiene of the equipment, but also led to a certain degree of environmental pollution. The accumulated ash and flue gas diffused everywhere, causing surrounding equipment and facilities to become dusty, making the working environment dirty and messy. Moreover, these pollutants diffused into the air, damaging the air quality in the boiler room and threatening the health of employees.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positive pressure device for the wall hole of a sootblower furnace, comprising... A sealing sleeve installed on the furnace wall; The outer barrel of the soot blower is inserted into the inside of the sealing sleeve at one end; It also includes a sealing assembly, which consists of a sealing element and a pressing element, wherein: The sealing element is fitted onto the outer barrel of the soot blower and fits against the open end face of the sealing sleeve; The pressing component is also fitted onto the sealing sleeve and abuts against the sealing component. The pressing component is fixedly connected to the sealing sleeve. Without the sealing component, a large amount of dust and smoke leakage will occur, which will have a serious negative impact on the cleanliness and hygiene of the equipment and cause a certain degree of environmental pollution. At the same time, the dust and smoke will spread everywhere, making the surrounding equipment and facilities dusty and the working environment dirty and messy. Moreover, these pollutants will spread into the air, damaging the air quality in the boiler room and threatening the health of employees.

[0006] Preferably, the sealing element is wool felt, with notches formed around its perimeter. The inner diameter of the wool felt is larger than the outer diameter of the outer barrel of the soot blower but smaller than the inner diameter of the sealing sleeve. The wool felt can seal the gap between the sealing sleeve and the outer barrel of the soot blower, thereby reducing leakage. The wool felt has high temperature resistance properties. This material is a known product and will not be described in detail here. Arc-shaped grooves are formed at equal angles around the perimeter of the wool felt.

[0007] Preferably, the pressing component is a pressing plate, and a connecting bolt runs through the surface of the pressing plate. The connecting bolt is screwed into the end face of the sealing sleeve after passing through the arc-shaped groove. After the connecting bolt is pressed against the pressing plate, the wool felt is pressed against it, so that the wool felt can be tightly attached to the opening of the sealing sleeve and the gap between the sealing sleeve and the outer barrel of the soot blower is eliminated.

[0008] Preferably, the pressing plate is also provided with a protective sleeve facing the furnace wall. The protective sleeve covers the connection between the sealing sleeve and the outer barrel of the sootblower. By setting the protective sleeve, external protection can be achieved, further improving the anti-leakage effect.

[0009] Preferably, one end of the protective sleeve is bonded to the end face of the pressing plate, while the other end of the protective sleeve has an annular groove, in which a magnetic ring is bonded. The magnetic ring magnetically attracts the sealing sleeve, and the protective sleeve is connected by magnetic attraction. This connection method is simple to operate.

[0010] Preferably, one end of the protective sleeve is further provided with a plurality of hooks, which are connected through the pressing plate, and the ends of the hooks are bent and limited to the end of the pressing plate away from the furnace wall, thereby improving the connection stability between the protective sleeve and the pressing plate.

[0011] Preferably, the outer barrel, pressing plate, and sealing sleeve of the soot blower are arranged in a concentric circle.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention successfully solves the problems of ash accumulation and flue gas leakage, greatly improving the surrounding environment, significantly enhancing hygiene and sanitation, and effectively alleviating environmental pollution. Furthermore, by preventing ash and flue gas from damaging and thinning the outer tube of the sootblower, the service life of the IK545 sootblower is significantly extended, its safe and stable operation is significantly improved, the probability of equipment failure is reduced, and the normal operation of the boiler system is guaranteed.

[0013] Furthermore, before the improvement, employees needed to frequently clean up leaking dust and fumes, resulting in high workload and low efficiency. Now, with the leakage problem resolved, the frequency of employee cleaning has been significantly reduced, and the workload has been significantly decreased, allowing employees to devote more energy to other important production and maintenance work, thus effectively promoting the efficient operation of the company's production.

[0016] 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.

[0017] Please see Figures 1 to 5 This utility model provides a technical solution: a positive pressure device for the wall hole of a sootblower furnace, comprising... A sealing sleeve 100 is installed on the furnace wall 400; The outer barrel of the soot blower is 200, with one end inserted into the inside of the sealing sleeve 100; It also includes a sealing assembly, which consists of a sealing element and a pressing element, wherein: The sealing element is fitted onto the outer barrel 200 of the sootblower and fits against the open end face of the sealing sleeve 100; The pressing component is also fitted onto the sealing sleeve 100 and abuts against the sealing component. The pressing component is fixedly connected to the sealing sleeve 100. Without the sealing component, a large amount of dust and smoke leakage will occur, which will have a serious negative impact on the cleanliness of the equipment and cause a certain degree of environmental pollution. At the same time, the dust and smoke will spread everywhere, making the surrounding equipment and facilities dusty and the working environment dirty and messy. Moreover, these pollutants will spread into the air, damaging the air quality in the boiler room and threatening the health of employees.

[0018] In this embodiment, preferably, the sealing element is wool felt 301. The wool felt 301 has notches around its perimeter. The inner diameter of the wool felt 301 is larger than the outer diameter of the sootblower outer gun barrel 200 but smaller than the inner diameter of the sealing sleeve 100. The wool felt 301 can seal the gap between the sealing sleeve 100 and the sootblower outer gun barrel 200, thereby reducing leakage. The wool felt 301 has high temperature resistance. The high temperature resistant wool felt 301 is soft and elastic. When it is applied to parts such as furnace wall holes, it can tightly fill the gaps. Its tight fiber mesh structure can effectively block the leakage of ash and flue gas, just like installing a tight "protective net" at the furnace wall holes. It solves the problem of ash accumulation and flue gas leakage from the root, greatly improves the hygiene of the equipment, and reduces environmental pollution. Meanwhile, its excellent wear resistance allows it to maintain structural integrity even under long-term ash accumulation friction and flue gas scouring, making it less prone to damage and deformation, providing a strong guarantee for the stable operation of the sootblower and extending the service life of the IK545 sootblower. Furthermore, the thermal insulation performance of the high-temperature resistant wool felt 301 is also crucial during the optimization process. The air trapped between its fibers forms an insulating layer that effectively reduces heat loss around the sootblower caused by high temperatures, lowering the risk of equipment malfunction due to excessive temperature fluctuations and further enhancing the safe and stable operation of the IK545 sootblower. Moreover, since the problems of ash accumulation and flue gas leakage are resolved, employees no longer need to clean frequently. The use of high-temperature resistant wool felt 301 indirectly reduces the workload of employees, allowing them to devote more energy to other production and maintenance work, thus significantly promoting the efficient operation of the enterprise. This material is a known product and will not be described in detail here. Arc-shaped grooves are formed at equal angles around the perimeter of the wool felt 301.

[0019] In this embodiment, preferably, the pressing component is a pressing plate 302. A connecting bolt 303 passes through the surface of the pressing plate 302. The connecting bolt 303 is screwed into the end face of the sealing sleeve 100 after passing through the arc-shaped groove. After the connecting bolt 303 abuts against the pressing plate 302, the wool felt 301 is pressed against it, so that the wool felt 301 can fit tightly against the opening of the sealing sleeve 100 and eliminate the gap between the sealing sleeve 100 and the outer barrel 200 of the soot blower.

[0020] In this embodiment, preferably, a protective sleeve 304 is also provided on the pressing plate 302 facing the furnace wall 400. The protective sleeve 304 covers the connection between the sealing sleeve 100 and the outer barrel 200 of the soot blower. By setting the protective sleeve 304, external protection can be achieved, further improving the leak prevention effect.

[0021] In this embodiment, preferably, one end of the protective sleeve 304 is bonded to the end face of the pressing plate 302, while the other end of the protective sleeve 304 is provided with an annular groove 307. A magnetic ring 305 is bonded in the annular groove 307. The magnetic ring 305 is magnetically attracted to the sealing sleeve 100, and the connection of the protective sleeve 304 is achieved by magnetic attraction. This connection method is simple to operate.

[0022] In this embodiment, preferably, one end of the protective sleeve 304 is also fixed with a plurality of hooks 306, which are connected through the pressing plate 302, and the ends of the hooks 306 are bent and limited at one end of the pressing plate 302 away from the furnace wall 400, thereby improving the connection stability between the protective sleeve 304 and the pressing plate 302.

[0023] In this embodiment, preferably, the outer barrel 200 of the soot blower, the pressing plate 302, and the sealing sleeve 100 are arranged in a concentric circle.

[0024] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
