Description

Technical Field

[0001] This utility model relates to the field of shock wave soot blower technology, specifically to a jet pipe for an air shock wave soot blower. Background Technology

[0002] In many industrial production sectors, such as thermal power generation, chemical industry, and metallurgy, the efficient and stable operation of various heat exchange equipment (such as boilers, heating furnaces, and heat exchangers) plays a crucial role. However, during long-term operation, ash inevitably accumulates on the heated surfaces of these devices. Ash accumulation not only reduces heat exchange efficiency, leading to energy waste and increased production costs, but it can also affect the normal operation of the equipment, causing a series of safety hazards such as localized overheating and corrosion. To solve the ash accumulation problem in heat exchange equipment, air shockwave soot blowers have emerged. These blowers generate high-intensity shockwave airflow to impact the ash on the heated surfaces, causing the ash to fall off and restoring the normal heat transfer performance of the heat exchange equipment. Among the many components of an air shockwave soot blower, the jet pipe, as the key component that directly outputs the shockwave airflow, directly affects the soot blowing effect.

[0003] Traditional air shockwave sootblower nozzles mostly employ a fixed structure, meaning their spray angle cannot be changed after manufacturing. In practical applications, the internal heating surface structure of industrial heat exchange equipment is often complex, and ash accumulation is frequently distributed in various locations. Fixed-angle nozzles struggle to comprehensively and accurately cover all areas requiring sootblowing, resulting in some ash remaining unremoved and impacting overall sootblowing performance and heat exchange efficiency. For example, in the flame deflector areas of large boilers or the tube bundle gaps of economizers, fixed-angle nozzles often fail to accurately direct the shockwave airflow to these concealed and tricky-angled ash-accumulating areas, leading to persistent ash buildup in these regions.

[0004] In summary, given the shortcomings in soot blowing flexibility caused by the fixed angle of the traditional air shock wave soot blower nozzle, a new type of air shock wave soot blower nozzle is introduced to improve this. Utility Model Content

[0013] 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.

[0014] Please see Figure 1-2 This utility model provides a technical solution: an air shock wave soot blower spray pipe, including a shock wave soot blower body 1, brackets 2 installed on both the left and right sides of the bottom end of the shock wave soot blower body 1, a first connecting pipe 3 provided on the front side of the shock wave soot blower body 1, and a second connecting pipe 4 provided on the top end of the shock wave soot blower body 1. The shock wave soot blower body 1, the first connecting pipe 3, and the second connecting pipe 4 are existing public technologies, which are well known to those skilled in the art. This solution optimizes and improves the spray pipe, and the existing unimproved structure and principle will not be described in detail here. A connecting seat 5 is installed on the top end of the second connecting pipe 4, and a sealing bearing 6 is installed on one end of the upper surface of the connecting seat 5. A spray pipe 7 is installed on the other end of the sealing bearing 6. Teeth 8 are installed on the circumference of the outer wall of the spray pipe 7. A base 9 is provided on the outer wall of the connecting seat 5. A motor 10 is screwed to the top end of the base 9. A gear 11 is installed on the output end of the upper surface of the motor 10. The gear 11 and the teeth 8 are meshed with each other.

[0015] As a preferred option, the connecting seat 5 is further designed in a trumpet shape, which can improve the shock wave impact force.

[0016] As a preferred option, the teeth 8 and gear 11 are matched and their positions correspond.

[0017] All electrical components mentioned in this solution are existing technologies, and their models are only one of them. Any electrical component that meets the requirements of this solution can be used.

[0018] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control. The specific work is as follows.

[0019] In use, the main body 1 of the shockwave sootblower is turned on. The shockwave generated inside the main body 1 passes through the second connecting pipe 4, the connecting seat 5, and the sealed bearing 6, and is finally discharged through the jet pipe 7, thus enabling conventional shockwave sootblowing treatment of the outside environment. The motor 10 is turned on, which drives the gear 11 to rotate. Since the gear 11 and the teeth 8 mesh with each other, the rotation of the gear 11 causes the teeth 8 to drive the jet pipe 7 to rotate, thus adjusting the jet angle of the jet pipe 7 according to the usage requirements. After the angle is adjusted, the motor 10 is turned off, the gear 11 stops rotating, and the position of the jet pipe 7 is locked by the meshing between the gear 11 and the teeth 8, thus completing the jet angle adjustment of the jet pipe 7. This device has a simple structure and reasonable design. It can adjust the position angle of the shockwave jet sootblowing according to the usage requirements. Compared with traditional fixed-angle sootblowing, it greatly improves the sootblowing range, making the soot cleaning more comprehensive and thorough, with significant effects. It is easy to use, highly practical, and suitable for widespread application.
