Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of soot cleaning equipment, in particular to an efficient air shock wave soot blower system and a use method thereof. BACKGROUND

[0002] During the operation of a boiler, a large amount of dust particles, loose materials, cohesive materials and deposits are accumulated on the heating surface for a long time, which leads to an increase in the exhaust gas temperature at the tail of the boiler and a decrease in the thermal efficiency. The traditional gas shock wave soot blower has the problems of strong directionality, dead angle of soot removal, high fuel cost, safety hazard, uncontrollable impact of shock wave energy on the furnace wall, and poor system stability caused by the change of fuel gas ratio. Although the existing air shock wave soot blower is independently arranged and uses compressed gas as the gas source, it has a certain safety and soot removal effect, but the soot blowing coverage is narrow, and it is difficult to meet the soot cleaning demand of a flue with a width (length) of 15-20 meters. SUMMARY

[0003] The present application aims to provide an efficient air shock wave soot blower system and a use method thereof to solve the problems of the prior art, and has the advantages of simple structure, effectively expanded soot blowing coverage, effectively enhanced soot blowing effect, effectively removed soot in the flue, and improved thermal efficiency of the boiler.

[0004] To achieve the above-mentioned purpose, the present application provides the following solutions. The present application provides an efficient air shock wave soot blower system, which comprises at least one shock wave generating mechanism and a control mechanism. The shock wave generating mechanism comprises two shock wave generating devices, the two shock wave generating devices are oppositely arranged on the two sides of the heat exchange equipment, and the shock wave injection ports of the two shock wave generating devices are oppositely arranged. The control mechanism is in communication or hard-wired connection with each shock wave generating device, and is used for controlling the time sequence of the generation of shock waves by each shock wave generating device, so that the shock waves generated by the two shock wave generating devices collide at a predetermined spatial position in the heat exchange equipment.

[0005] Preferably, the shock wave generating device is an air shock wave soot blower.

[0006] Preferably, the air shock wave soot blower comprises a gas supply pipeline, a shock wave generator and a jet assembly. One end of the gas supply pipeline is in communication with an air source, and the other end is in communication with the shock wave generator and converts the compressed gas delivered by the gas supply pipeline into air shock waves. The jet assembly is connected with the output end of the shock wave generator, and is used for guiding and injecting the air shock waves into the heat exchange equipment.

[0007] Preferably, the injection assembly includes an injection pipe, a first solenoid valve, and a shock nozzle. One end of the injection pipe is connected to a shock generator, and the other end is connected to the shock nozzle. The end of the shock nozzle that extends into the interior of the heat exchange device is the shock injection port, and the shock injection ports of the two oppositely arranged shock generators are collinear. The first solenoid valve is disposed on the injection pipe and communicates with or is hardwired connected to the control mechanism to control the on / off state of the injection pipe to adjust the timing of the air shock wave injection.

[0008] Preferably, the air supply pipeline includes a branch pipeline, a manual ball valve, a Y-type filter, and a second solenoid valve. One end of the branch pipeline is connected to the main pipeline of the air source, and the other end is connected to the shock wave generator. The manual ball valve is located on the branch pipeline, the Y-type filter is located on the branch pipeline on the side away from the main pipeline, and the second solenoid valve is located on the branch pipeline on the side away from the manual ball valve. The second solenoid valve is communicatively or hardwired connected to the control mechanism to control the air supply from the branch pipeline to the shock wave generator.

[0009] Preferably, it also includes a pressure gauge, which is disposed on the branch line and located on the side of the second solenoid valve away from the Y-type filter.

[0010] Preferably, it also includes a metal flexible hose, one end of which is connected to and communicates with the branch pipe, and the other end of which is connected to and communicates with the shock wave generator.

[0011] Preferably, the control mechanism includes a controller and a timing control module connected to the controller. The timing control module is used to send control commands to each of the shock wave generating devices according to a preset program or external input signals, so as to precisely control the time interval between the generation of air shock waves by two oppositely arranged shock wave generating devices.

[0012] Preferably, there are multiple shock wave generating mechanisms, which are spaced apart along the length or height of the heat exchange equipment.

[0013] The present invention also provides a method of using the high-efficiency air shock wave sootblower system as described in any of the preceding claims, comprising the following steps: Start the control mechanism and set the shock wave emission timing parameters of the two oppositely positioned shock wave generators according to the ash accumulation distribution of the heat exchange equipment; The control mechanism sends a start command to the shock wave generator. The two shock wave generators, which are set opposite each other, emit shock waves sequentially or simultaneously according to the precise time interval set by the control mechanism. This causes the two shock waves to collide head-on at a preset spatial position inside the heat exchange equipment, forming a shock wave superposition effect and generating a composite shock wave with a pressure higher than the peak pressure of a single shock wave. The composite shock wave spreads outward in the collision area, forming a three-dimensional shock wave front. This front completely peels off and breaks up the stubborn ash layer that is difficult to remove from the gaps between the tubes of the heat exchange equipment, and carries the peeled ash to the flue gas outlet.

[0014] The present invention achieves the following technical effects compared to the prior art: This invention provides a high-efficiency air shock wave sootblower system and its usage method. By employing a structure of two opposing shock wave generators and coordinating precise timing control to achieve shock wave collision and superposition, the coverage and cleaning intensity of the sootblowing system are significantly improved. The composite shock wave formed by the collision of the two shock waves at a preset spatial position has a peak pressure far exceeding that of a single shock wave, effectively penetrating the ash layer deep within the tube bundle gaps and solving the problem of dead zones in traditional single-point jet cleaning.

[0015] Furthermore, the system uses compressed air as the working medium, avoiding the drawbacks of gas shock wave generators such as high fuel costs, significant safety hazards, and unstable combustion ratios. Moreover, through the coordinated configuration of solenoid valve groups and pressure monitoring elements, it achieves precise control of shock wave energy and safe and reliable system operation.

[0016] Furthermore, the array arrangement of multiple shock wave generating mechanisms along the length or height of the flue can further expand the ash removal coverage area, meet the continuous ash removal requirements of wide flues in large boilers, thereby effectively reducing the exhaust gas temperature and improving the boiler thermal efficiency.

It has a simple structure, effectively expands the sootblowing coverage area, effectively enhances the sootblowing effect, effectively removes ash accumulation in the flue, and improves boiler thermal efficiency.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 This embodiment provides a high-efficiency air shock wave soot blower system, such as Figure 1 As shown, it includes: at least one shock wave generating mechanism and a control mechanism. The shock wave generating mechanism includes two shock wave generating devices, which are respectively arranged opposite to each other on both sides of the heat exchange equipment 12, and the shock wave nozzles of the two shock wave generating devices are arranged facing each other. The control mechanism is connected to each shock wave generating device by communication or hard-wire connection, and is used to control the timing of the shock wave generation by each shock wave generating device, so that the shock waves generated by the two shock wave generating devices collide at a preset spatial position in the heat exchange equipment 12. By arranging shock wave generating devices opposite to each other on both sides of the heat exchange equipment 12 and spraying shock waves towards each other, and by combining the control mechanism to precisely control the timing of shock wave generation, the shock waves collide at the preset spatial position, which can generate a shock wave similar to an explosion wave, causing the compressed air to change from linear motion to diffusion in all directions, expanding the shock wave coverage area, enhancing the soot blowing effect, and effectively removing the ash accumulation in different positions in the heat exchange equipment 12.

[0023] In a preferred embodiment, the shock wave generating device is an air shock wave soot blower. The air shock wave soot blower uses compressed air as its air source. Compared with the gas shock wave soot blower, it has higher safety and avoids risks such as combustion and explosion. At the same time, the air source is easy to obtain and the cost is low, making it suitable for widespread application in the cleaning work of various heat exchange equipment 12.

[0024] In a preferred embodiment, the air shock wave sootblower includes an air supply pipeline, a shock wave generator 8, and a jet assembly. One end of the air supply pipeline is connected to an air source, and the other end is connected to the shock wave generator 8, which converts the compressed gas supplied by the air supply pipeline into an air shock wave. The jet assembly is connected to the output end of the shock wave generator 8 and is used to guide and jet the shock wave into the heat exchange device 12. The functions of each part of the air shock wave sootblower are clearly defined. The air supply pipeline is responsible for supplying compressed gas, the shock wave generator 8 converts it into an air shock wave, and the jet assembly accurately guides and jets the shock wave into the heat exchange device 12, ensuring that the air shock wave can act on the ash accumulation area to achieve the purpose of ash removal. The coordinated work of each part ensures the stable operation of the sootblower.

[0025] In a preferred embodiment, the injection assembly includes an injection pipe 9, a first solenoid valve 10, and a shock nozzle 11. One end of the injection pipe 9 is connected to the shock generator 8, and the other end is connected to the shock nozzle 11. The end of the shock nozzle 11 that extends into the heat exchanger 12 serves as the shock injection port. The shock injection ports of the two opposing shock generators are collinear. The first solenoid valve 10 is mounted on the injection pipe 9 and communicates with or is hardwired to the control mechanism. It controls the on / off state of the injection pipe 9 to adjust the timing of the air shock wave injection. The injection pipe 9 connects the shock generator 8 and the shock nozzle 11 to ensure effective transmission of the air shock wave. The first solenoid valve 10 communicates with or is hardwired to the control mechanism, enabling precise control of the injection pipe 9 according to control commands. This accurately adjusts the timing of the air shock wave injection, and, in conjunction with the control mechanism's control of the air shock wave generation sequence, ensures that the air shock wave collides accurately at a preset position, enhancing the accuracy and effectiveness of soot blowing. The collinearity of the shock injection ports of the two opposing shock generators ensures that the air shock waves can propagate accurately towards each other and collide.

[0026] In a preferred embodiment, the air supply pipeline includes a branch pipeline 2, a manual ball valve 3, a Y-type filter 4, and a second solenoid valve 5. One end of the branch pipeline 2 is connected to the main air supply pipeline 1, and the other end is connected to the shock generator 8. The manual ball valve 3 is installed on the branch pipeline 2, and the Y-type filter 4 is installed on the branch pipeline 2 on the side of the manual ball valve 3 away from the main air supply pipeline 1. The second solenoid valve 5 is installed on the branch pipeline 2 on the side of the Y-type filter 4 away from the manual ball valve 3. The second solenoid valve 5 communicates with or is hardwired to the control mechanism to control the air supply from the branch pipeline 2 to the shock generator 8. The branch pipeline 2 connects the air supply source and the shock generator 8. The manual ball valve 3 allows manual control of the air supply pipeline, facilitating equipment debugging, maintenance, and emergency handling. The filter can filter impurities in the compressed air, protect the shock generator 8, and extend its service life; the second solenoid valve 5 communicates with the control mechanism or is hardwired to precisely control the air supply according to the control command, ensuring that the shock generator 8 obtains the air source at the appropriate time, thereby generating an air shock wave as required.

[0027] In a preferred embodiment, the air supply line further includes a pressure gauge 7. The pressure gauge 7 is installed on the branch line 2 and located on the side of the second solenoid valve 5 away from the Y-type filter 4, or the pressure gauge 7 is installed on the shock generator 8. The pressure gauge 7 can display the air pressure in the shock generator 8 in real time, which is convenient for operators to monitor the air supply pressure and ensure that the shock generator 8 works within a safe pressure range. At the same time, it provides data support for the precise control of air shock wave energy.

[0028] In a preferred embodiment, the gas supply pipeline further includes a metal hose 6. One end of the metal hose 6 is connected to and communicates with the branch pipeline 2, and the other end is connected to and communicates with the shock wave generator 8. The metal hose 6 has good flexibility, which can effectively compensate for errors in the equipment installation process and vibrations and displacements generated during equipment operation, avoid pipeline damage caused by rigid connection, enhance the reliability and stability of the gas supply pipeline connection, and ensure stable delivery of compressed gas to the shock wave generator 8.

[0029] In a preferred embodiment, the control mechanism includes a controller and a timing control module connected to the controller. The timing control module sends control commands to each shock wave generator according to a preset program or external input signal to precisely control the time interval between the generation of air shock waves by two oppositely arranged shock wave generators. The controller and the timing control module work together to precisely control the time interval between the generation of air shock waves by the shock wave generators according to a preset program or external input signal, ensuring that the air shock waves generated by the two oppositely arranged shock wave generators collide accurately at a preset spatial position within the heat exchanger 12, meeting the dust removal requirements of different dust accumulation distributions within the heat exchanger 12, and improving the targeting and effectiveness of soot blowing.

[0030] In a preferred embodiment, there are multiple shock wave generating mechanisms, which are spaced apart along the length or height of the heat exchange device 12. This arrangement allows the air shock waves to cover a wider area within the heat exchange device 12, further enhancing the soot blowing effect and ensuring that accumulated ash in different locations within the entire heat exchange device 12 can be effectively removed. This is particularly suitable for large or complex heat exchange devices 12.

[0031] In a preferred embodiment, the device further includes a support bracket. The shock generator 8 is mounted on the outer wall of the heat exchanger 12 via the bracket. The bracket features an adjustable structure, including a fixed base, a height adjustment rod, and an angle adjustment seat. The fixed base is reliably connected to the outer wall of the heat exchanger 12 or the flue steel structure via expansion bolts. The height adjustment rod has multiple positioning holes along the vertical direction and achieves multi-level height locking with the fixed base via a pin. The angle adjustment seat is connected to the top of the height adjustment rod via a slewing bearing, allowing for ±15° angle fine-tuning in the horizontal plane. The shock generator 8 is bolted to the angle adjustment seat via a flange. This support structure can adapt to the installation requirements of heat exchangers 12 of different specifications, ensuring precise positioning of the shock jet's axis, while providing convenient operating space for daily maintenance and nozzle replacement of the shock generator 8.

[0032] In a preferred embodiment, a sealing assembly is further included. The sealing assembly is disposed at the through hole between the shock nozzle 11 and the wall of the heat exchange device 12. The sealing assembly includes a metal flange sleeve, high-temperature resistant ceramic fiber filler, and a compression cap. The metal flange sleeve is welded to the wall of the heat exchange device 12. The shock nozzle 11 extends into the device through the central hole of the sleeve. The high-temperature resistant ceramic fiber filler fills the annular gap between the sleeve and the nozzle. The compression cap is connected to the sleeve flange by bolts and compacts the filler. This sealing assembly can maintain reliable sealing performance under high-frequency vibration conditions of the shock nozzle 11, preventing high-temperature flue gas from leaking out. At the same time, it allows for slight displacement of the nozzle due to thermal expansion, avoiding structural damage caused by stress concentration.

[0033] Example 2 This embodiment provides a method for using a high-efficiency air shock wave soot blower based on the system of Embodiment 1, specifically including the following operation steps: Step S1: System Installation and Airtightness Test. Complete the mechanical installation of each shock wave generating mechanism according to the device structure of Example 1, ensuring that the shock wave nozzle axes of the two oppositely positioned shock wave generating devices are collinear and the distance between them is equal to the internal width of the heat exchanger 12 at that cross-section. Connect the air supply pipeline to the main compressed air pipeline 1 in the plant area. Open the manual ball valve 3 and the second solenoid valve 5 sequentially to slowly fill the system with compressed air to 1.2 times the working pressure. Maintain the pressure for 30 minutes. Check for leaks at each flange interface, threaded connection, and metal hose 6 joint by applying soapy water. After confirming that the airtightness is qualified, release the pressure to zero.

[0034] Step S2: Control Parameter Setting and Calibration. Start the control mechanism and determine the three-dimensional coordinates of the preset collision space position according to the design drawings of the heat exchanger 12. Input these coordinates into the controller as the target point for the air shock wave collision. Set the air shock wave emission timing parameters through the timing control module, including the start-up interval of a single shock wave generator, the emission time difference between the two shock wave generators, and the cycle working period. For standard operating conditions, the emission time difference Δt between the two shock wave generators is set to equal the shock wave propagation distance divided by the air shock wave propagation speed in the air, where the propagation distance is the distance from the shock wave nozzle to the preset collision position. Before the first operation, use a high-speed pressure sensor to calibrate the shock wave pressure at the preset collision position, adjusting the emission time difference so that the measured peak collision pressure reaches more than 95% of the theoretically calculated value.

[0035] Step S3: Shock Wave Generation and Collision Blowing. The control mechanism sends control commands to the first solenoid valve 10 and the second solenoid valve 5 according to the set timing. The second solenoid valve 5 opens, allowing compressed air to enter the shock wave generator 8 through the Y-type filter 4. The shock wave generator 8 converts the compressed gas energy into pulsed air shock waves. The first solenoid valve 10 precisely controls the timing of the shock wave injection, causing the two opposing air shock waves to collide head-on at a preset spatial position. The peak pressure of the high-pressure zone formed at the moment of collision can reach 2.5 to 3 times that of a single shock wave. The composite shock wave spreads spherically outward from the collision point, and its effective radius of action is 200% to 300% larger than that of a single shock wave, effectively stripping ash layers with a tube bundle gap depth exceeding 200 mm.

[0036] Step S4: Operation Monitoring and Adaptive Adjustment. During system operation, the control mechanism collects real-time air supply pressure data from pressure gauge 7, on / off status feedback signals from the first solenoid valve 10 and the second solenoid valve 5, and visual images of ash removal collected by the optional high-temperature industrial television. When the shock wave pressure peak value of a single shock wave generator is detected to be lower than the set threshold three times consecutively, the controller automatically triggers an alarm and prompts the user to check the filter blockage of that branch or the wear status of the shock wave generator 8. Based on the ash accumulation rate changes under different operating loads of the heat exchange equipment 12, the operator can adjust the shock wave emission frequency and timing parameters online through the human-machine interface of the control mechanism to achieve dynamic matching of the soot blowing intensity.

[0037] Step S5: Shutdown Maintenance and Safety Protection. During normal shutdown, the control mechanism executes the following sequence: first, stop the shock wave jet, then cut off the air supply. Specifically, it first closes the first solenoid valve 10 to stop the shock wave jet; after a 5-second delay, it closes the second solenoid valve 5 to cut off the air supply; finally, it closes the manual ball valve 3. The system is equipped with an emergency shutdown protection function. When the air supply pressure exceeds the safety limit or the shock wave generator 8 temperature rises abnormally, the controller immediately closes all solenoid valves simultaneously and opens the pressure relief valve to ensure system safety.

[0038] In a preferred embodiment, the shock wave emission mode in step S3 includes a continuous collision mode and an alternating scanning mode. The continuous collision mode is suitable for centralized cleaning of areas with severe dust accumulation, where two shock wave generators cyclically emit air shock waves at intervals of 0.5 to 2 seconds. The alternating scanning mode is suitable for large-area uniform dust removal, where the control mechanism drives multiple shock wave generators to start sequentially along a set path, forming a mobile air shock wave collision area that gradually covers the entire heat exchanger 12 cross section.

[0039] In a preferred embodiment, step S4 further includes an intelligent control strategy based on ash accumulation monitoring feedback. By arranging differential pressure sensors and temperature sensors at the flue gas outlet of the heat exchanger 12, the resistance coefficient and heat exchange efficiency decay rate on the flue gas side are calculated in real time. When the resistance coefficient growth rate exceeds a set threshold or the heat exchange efficiency decreases by more than 5%, the control mechanism automatically starts the shock wave soot blowing program and adaptively selects the shock wave emission intensity and frequency according to the severity of ash accumulation, so as to achieve soot blowing on demand and avoid tube bundle wear and compressed air waste caused by excessive soot blowing.

[0040] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
