Description

Technical Field

[0001] The present invention relates to the technical field of soot blowers, and more particularly to a rotary whistle type acoustic soot blower that prevents jamming. Background Art

[0002] A rotary whistle type acoustic soot blower is a device that uses acoustic energy to remove accumulated ash in equipment such as boilers. It converts the energy of compressed air into acoustic energy through a high-power rotary whistle type generating device, modulates acoustic waves of a certain intensity, and sends them into the space area of the accumulated ash in the furnace body. Its sound source uses a wide frequency range of acoustic waves with adjustable frequencies from 100 Hz to 600 Hz, having a long wavelength, large amplitude, slow energy attenuation, and strong diffraction and reflection capabilities. Under the action of the sound field energy, the air molecules and dust particles in the accumulated ash area generate violent oscillations, destroying and preventing the combination of dust particles on the surface of the heat exchanger or between particles, making them in a suspended fluidized state, so as to be carried away by the flue gas flow or automatically fall off, thereby achieving the purpose of removing accumulated ash.

[0003] Existing acoustic soot blowers are prone to jamming, and dust is likely to accumulate at the output end of the acoustic wave, resulting in acoustic wave attenuation and affecting the dust removal effect. Therefore, we propose a rotary whistle type acoustic soot blower that prevents jamming. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a rotary whistle type acoustic soot blower that prevents jamming, including:

[0005] A mounting plate, on the surface of which mounting holes are provided, and a plurality of the mounting holes are evenly arranged.

[0006] A soot blowing mechanism, which is fixedly connected to the inner side of the mounting plate.

[0007] Among them, the soot blowing mechanism includes:

[0008] A soot blowing assembly, the outer side of which is fixedly connected to the inner side of the mounting plate, and the soot blowing assembly is fixedly connected to the side of the acoustic energy converter and is fixedly connected to the output end of the acoustic energy converter.

[0009] An acoustic energy converter, which is fixedly connected to the side of the soot blowing assembly. A filter is fixedly connected to the side of the soot blowing assembly away from the acoustic energy converter. The filter is used to connect to an air compressor to filter the input compressed air and convert its output energy into acoustic energy.

[0010] A pipeline assembly, which is fixedly connected to the side of the acoustic energy converter away from the soot blowing assembly, and the pipeline assembly is arranged in a horn shape.

[0011] The mounting plate will be fixedly connected inside equipment such as boilers through the mounting holes, thereby fixing the soot blower of the present invention at the position of the equipment such as boilers that needs to be cleaned. Connect the filter to the air compressor that supplies energy. Compress the air through the air compressor to generate compressed air with a certain pressure and flow rate. The compressed air sequentially passes through the filter and the soot blowing assembly, and finally enters the acoustic energy converter. After the compressed air enters the acoustic energy converter, its pressure energy and kinetic energy are converted into acoustic energy, thereby generating high-intensity sound waves. The sound waves pass through the pipeline assembly and finally remove the ash deposits on parts such as the tail flue, heating surface, and flue gas denitrification separation layer of the boiler. The pipeline assembly is set in a horn shape. The horn-shaped structure can concentrate the sound waves in a specific direction, making the sound wave energy propagate within a certain angular range. This is because the gradually expanding shape of the horn mouth guides the sound waves to propagate along the axial direction, reducing the scattering of the sound waves in other directions and enabling more concentrated cleaning of the ash surface.

[0012] Further, the soot blowing assembly includes a shield. The outer side surface of the shield is fixedly connected to the inner side surface of the mounting plate, and the shield is made of a heat-dissipating material. The inner side surface of the shield is fixedly connected with a piston assembly. The shield is used to protect the piston assembly. Made of a heat-dissipating material, the shield can also dissipate heat from the piston assembly in time, avoiding the drying of its lubricating oil and the occurrence of jamming.

[0013] Further, a first connecting pipe and a second connecting pipe are respectively fixedly connected to both sides of the shield. The end of the first connecting pipe away from the shield is fixedly connected to the filter. The second connecting pipe is fixedly connected to the side of the acoustic energy converter away from the pipeline assembly, and the second connecting pipe is fixedly connected to the input end of the acoustic energy converter. The compressed air sequentially passes through the filter, the first connecting pipe, and the second connecting pipe, and finally enters the acoustic energy converter. The acoustic energy converter converts it into sound waves, and the sound waves pass through the pipeline assembly to clean the equipment.

[0014] Further, fixing rings are fixedly connected to the outer side surfaces of the first connecting pipe and the second connecting pipe, and the two fixing rings are respectively arranged at the ends of the first connecting pipe and the second connecting pipe that are away from each other. Support rods are fixedly connected to the sides of the two fixing rings that are close to each other. The support rods are inclined, and the support rods are evenly distributed along the circumference of the fixing rings. The side of the support rod away from the fixing ring is fixedly connected with a connecting block, and the sides of the connecting blocks on both sides of the shield away from the support rods are respectively fixedly connected to the outer side surfaces of the first connecting pipe and the second connecting pipe. The support rods, connecting blocks, fixing rings, the first connecting pipe, and the support rods, connecting blocks, fixing rings, and the second connecting pipe on the other side all form a triangular support, which can stably support the first connecting pipe and the second connecting pipe, avoiding the inclination or deviation of the first connecting pipe and the second connecting pipe when the compressed air passes through, preventing the influence on the passage of air, and also preventing the piston assembly from getting stuck, further avoiding the occurrence of jamming.

[0015] Further, the piston assembly includes a fixing plate which is fixedly connected to the inner side surface of the shield, and the fixing plate is arranged directly above the first connecting pipe. A hydraulic rod is fixedly connected to the inner side surface of the fixing plate. One side of the hydraulic rod away from the fixing plate is fixedly connected with a piston, and the piston is fixedly connected to the output end of the hydraulic rod. Both sides of the piston are slidably connected to the mutually approaching sides of the first connecting pipe and the second connecting pipe. When the hydraulic rod is started, the hydraulic rod drives the piston to move up and down, and the piston opens and closes the first connecting pipe and the second connecting pipe, automatically controlling the start and stop of the soot blower, improving the accuracy and efficiency of the soot blowing operation, reducing manual intervention, and at the same time facilitating the centralized management and monitoring of the entire soot blowing system.

[0016] Further, a protective sleeve is fixedly connected to the side of the fixing plate close to the piston. A telescopic sleeve is fixedly connected to the side of the protective sleeve close to the piston. The side of the telescopic sleeve away from the protective sleeve is fixedly connected to the outer surface of the output end of the hydraulic rod. The output end of the hydraulic rod expands and contracts, driving the telescopic sleeve to extend or fold, adapting to the length change of the hydraulic rod. The protective sleeve protects the telescopic position of the hydraulic rod, preventing the lubricating oil from contacting the outside air, preventing the lubricating oil from drying out, and preventing jamming.

[0017] Further, the telescopic sleeve is made of a high-temperature resistant elastic material. The side of the telescopic sleeve away from the fixing plate is in communication with the outside. When the piston rises, the telescopic sleeve contracts and ejects air to clean the surface of the piston, preventing jamming. When the piston descends, the telescopic sleeve resumes and refills with air.

[0018] Further, a tapered tube is fixedly connected to the side of the telescopic sleeve away from the protective sleeve. The inner cavity of the tapered tube is in communication with the inner cavity of the telescopic sleeve, and a plurality of tapered tubes are evenly distributed along the circumferential direction of the telescopic sleeve. When the telescopic sleeve contracts, air enters the tapered tube through the telescopic sleeve and is finally ejected through the tapered tube to clean the surface of the piston. The tapered shape of the tapered tube can accelerate the ejection speed of the air flow and improve the cleaning effect.

[0019] Further, the pipeline assembly includes an elbow which is fixedly connected to the side of the acoustic energy converter away from the second connecting pipe and is fixedly connected to the output end of the acoustic energy converter. One end of the elbow away from the acoustic energy converter is fixedly connected to a horn-shaped tube. Sound waves enter the horn-shaped tube through the elbow and finally clean the accumulated ash. The horn-shaped tube can concentrate the sound waves in a specific direction, making the sound wave energy propagate within a certain angular range. This is because the gradually expanding shape of the horn mouth guides the sound waves to propagate along the axial direction, reducing the scattering of sound waves in other directions and enabling more concentrated cleaning of the surface of the accumulated ash.

[0020] Furthermore, for the oscillating rod, the oscillating rod is fixedly connected to the inner side surface of the horn tube. The cross-section of the oscillating rod is elliptical, and a plurality of the oscillating rods are evenly distributed along the circumferential direction of the horn tube. One end of the oscillating rod away from the nozzle of the horn tube is fixedly connected with an elastic column, and one end of the elastic column away from the oscillating rod is fixedly connected to the inner side surface of the horn tube. The sound wave drives the oscillating rod to swing, cleaning the nozzle of the horn tube, avoiding the loss of sound waves caused by the blockage of the nozzle. The oscillating rod with an elliptical cross-section is flat and not easy to accumulate dust, and can vibrate better with the sound wave to clean the nozzle of the horn tube. Moreover, when the flat oscillating rod swings, it shakes more violently, which can better clean the horn tube. The setting of the elastic column can further intensify the swing of the oscillating rod and obtain a better cleaning effect.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. By setting the soot blowing mechanism in the present invention, the protective cover is used to protect the piston assembly. The protective cover is made of a heat-dissipating material and can also dissipate heat from the piston assembly in time, avoiding the drying of its lubricating oil and the occurrence of jamming. The support rods, connecting blocks, fixed rings, the first connecting pipe, and the support rods, connecting blocks, fixed rings, and the second connecting pipe on the other side all form a triangular support, which can stably support the first connecting pipe and the second connecting pipe, preventing the first connecting pipe and the second connecting pipe from tilting or shifting when compressed air passes through, avoiding affecting the passage of air and also preventing the piston assembly from getting stuck, further avoiding the occurrence of jamming.

[0023] 2. By setting the piston assembly in the present invention, the telescopic sleeve extends or folds to adapt to the length change of the hydraulic rod. The protective sleeve protects the telescopic position of the hydraulic rod, avoiding the contact of the lubricating oil with the outside air, preventing the drying of the lubricating oil and the occurrence of jamming. The telescopic sleeve sprays out air to clean the surface of the piston, avoiding jamming. Moreover, the conical pipe can accelerate the spraying speed of the air flow and improve the cleaning effect.

[0024] 3. By setting the horn tube in the present invention, the sound wave can be concentrated in a specific direction, making the sound wave energy propagate within a certain angular range. This is because the gradually expanding shape of the horn mouth guides the sound wave to propagate along the axial direction, reducing the scattering of the sound wave in other directions and enabling more concentrated cleaning of the dust-accumulated surface.

[0025] 4. By setting the oscillating rod in the present invention, the sound wave drives the oscillating rod to swing, cleaning the nozzle of the horn tube, avoiding the loss of sound waves caused by the blockage of the nozzle. The oscillating rod with an elliptical cross-section is flat and not easy to accumulate dust, and can vibrate better with the sound wave to clean the nozzle of the horn tube. Moreover, when the flat oscillating rod swings, it shakes more violently, which can better clean the horn tube. The setting of the elastic column can further intensify the swing of the oscillating rod and obtain a better cleaning effect. Description of the Drawings

[0041] The acoustic energy converter 31 is fixedly connected to the side of the soot blowing assembly 33. A filter 32 is fixedly connected to the side of the soot blowing assembly 33 away from the acoustic energy converter 31. The filter 32 is used to connect to an air compressor to filter the input compressed air and convert the output energy into acoustic energy.

[0042] The pipeline assembly 34 is fixedly connected to the side of the acoustic energy converter 31 away from the soot blowing assembly 33, and the pipeline assembly 34 is arranged in a horn shape.

[0043] The mounting plate 1 is fixedly connected inside equipment such as a boiler through the mounting holes 2, so as to fix the soot blower of the present invention at the position that needs to be cleaned in equipment such as a boiler. The filter 32 is connected to an air compressor that supplies energy. The air compressor compresses the air to generate compressed air with a certain pressure and flow rate. The compressed air sequentially passes through the filter 32 and the soot blowing assembly 33, and finally enters the acoustic energy converter 31. After the compressed air enters the acoustic energy converter 31, its pressure energy and kinetic energy are converted into acoustic energy, thereby generating high-intensity sound waves. The sound waves pass through the pipeline assembly 34 and finally remove the ash deposits on parts such as the tail flue, heating surface, and flue gas denitration separation layer of the boiler. The pipeline assembly 34 is arranged in a horn shape, and the horn-shaped structure can concentrate the sound waves in a specific direction, so that the sound wave energy is concentrated and propagated within a certain angular range. This is because the gradually expanding shape of the horn mouth guides the sound waves to propagate along the axial direction, reducing the scattering of the sound waves in other directions, and enabling more concentrated cleaning of the ash deposit surface.

[0044] The soot blowing assembly 33 includes a protective cover 331.

The inner side surface of the protective cover 331 is fixedly connected with a piston assembly 334. The protective cover 331 is used to protect the piston assembly 334. Made of a heat-dissipating material, the protective cover 331 can also dissipate heat from the piston assembly 334 in a timely manner, avoiding the drying of its lubricating oil and preventing the occurrence of jamming.

[0045] On both sides of the shield 331, a first connecting pipe 332 and a second connecting pipe 333 are fixedly connected respectively. One end of the first connecting pipe 332 far from the shield 331 is fixedly connected to the filter 32. The second connecting pipe 333 is fixedly connected to the side of the acoustic energy converter 31 far from the pipeline assembly 34, and the second connecting pipe 333 is fixedly connected to the input end of the acoustic energy converter 31. Compressed air passes through the filter 32, the first connecting pipe 332, and the second connecting pipe 333 in sequence, and finally enters the acoustic energy converter 31. The acoustic energy converter 31 converts it into sound waves, and the sound waves clean the equipment through the pipeline assembly 34.

[0046] Fixed rings 335 are fixedly connected to the outer sides of the first connecting pipe 332 and the second connecting pipe 333 respectively. And the two fixed rings 335 are respectively arranged at the ends of the first connecting pipe 332 and the second connecting pipe 333 far from each other. On one side of the two fixed rings 335 close to each other, support rods 336 are fixedly connected. The support rods 336 are inclined, and the support rods 336 are evenly distributed along the circumferential direction of the fixed rings 335. On the side of the support rods 336 far from the fixed rings 335, connection blocks 337 are fixedly connected. And on the sides of the connection blocks 337 on both sides of the shield 331 far from the support rods 336, they are respectively fixedly connected to the outer sides of the first connecting pipe 332 and the second connecting pipe 333. The support rods 336, the connection blocks 337, the fixed rings 335, the first connecting pipe 332, and the support rods 336, the connection blocks 337, the fixed rings 335, and the second connecting pipe 333 on the other side all form triangular supports, which can stably support the first connecting pipe 332 and the second connecting pipe 333, prevent the first connecting pipe 332 and the second connecting pipe 333 from tilting or shifting when compressed air passes through, avoid affecting the passage of air, and also avoid the piston assembly 334 from getting stuck, further avoiding the occurrence of jamming phenomena.

[0047] The piston assembly 334 includes a fixing plate 3341. The fixing plate 3341 is fixedly connected to the inner side of the shield 331, and the fixing plate 3341 is arranged directly above the first connecting pipe 332. A hydraulic rod 3342 is fixedly connected to the inner side of the fixing plate 3341. On the side of the hydraulic rod 3342 far from the fixing plate 3341, a piston 3343 is fixedly connected, and the piston 3343 is fixedly connected to the output end of the hydraulic rod 3342. The two sides of the piston 3343 are respectively slidably connected to the sides of the first connecting pipe 332 and the second connecting pipe 333 close to each other. Start the hydraulic rod 3342, and the hydraulic rod 3342 drives the piston 3343 to move up and down. The piston 3343 opens and closes the first connecting pipe 332 and the second connecting pipe 333, automatically controls the start and stop of the soot blower, improves the accuracy and efficiency of the soot blowing operation, reduces manual intervention, and is also convenient for centralized management and monitoring of the entire soot blowing system.

[0048] On one side of the fixed plate 3341 close to the piston 3343, there is a protective sleeve 3345 fixedly connected. On one side of the protective sleeve 3345 close to the piston 3343, there is a telescopic sleeve 3344 fixedly connected. The side of the telescopic sleeve 3344 away from the protective sleeve 3345 is fixedly connected to the outer surface of the output end of the hydraulic rod 3342. The output end of the hydraulic rod 3342 expands and contracts, driving the telescopic sleeve 3344 to extend or fold, adapting to the length change of the hydraulic rod 3342. The protective sleeve 3345 protects the telescopic position of the hydraulic rod 3342, preventing the lubricating oil from contacting the outside air, preventing the lubricating oil from drying out, and preventing jamming.

[0049] The telescopic sleeve 3344 is made of a high-temperature resistant elastic material. The side of the telescopic sleeve 3344 away from the fixed plate 3341 communicates with the outside. When the piston 3343 rises, the telescopic sleeve 3344 contracts, and the telescopic sleeve 3344 ejects air to clean the surface of the piston 3343, preventing jamming. When the piston 3343 descends, the telescopic sleeve 3344 resumes and re-fills with air.

[0050] On the side of the telescopic sleeve 3344 away from the protective sleeve 3345, there is a tapered tube 3346 fixedly connected. The inner cavity of the tapered tube 3346 communicates with the inner cavity of the telescopic sleeve 3344, and a number of tapered tubes 3346 are evenly distributed along the circumferential direction of the telescopic sleeve 3344.

One end of the elbow 341 away from the acoustic energy converter 31 is fixedly connected to a horn tube 342. Sound waves enter the horn tube 342 through the elbow 341 and finally clean the dust. The horn-shaped horn tube 342 can concentrate the sound waves in a specific direction, making the sound wave energy propagate within a certain angular range. This is because the gradually expanding shape of the horn mouth guides the sound waves to propagate along the axial direction, reducing the scattering of sound waves in other directions and enabling more concentrated cleaning of the dust surface.

[0052] The oscillating rod 343 is fixedly connected to the inner side surface of the horn tube 342.

One end of the oscillating rod 343 far away from the orifice of the horn tube 342 is fixedly connected with an elastic column 344. One end of the elastic column 344 far away from the oscillating rod 343 is fixedly connected to the inner side surface of the horn tube 342. The sound wave drives the oscillating rod 343 to swing, cleaning the orifice of the horn tube 342, avoiding the loss of sound wave caused by the blockage of the orifice. The oscillating rod 343 with an elliptical cross-section is flat and not easy to accumulate dust, and can vibrate better with the sound wave to clean the orifice of the horn tube 342. Moreover, when the flat oscillating rod 343 swings, the shaking is more intense, which can better clean the horn tube 342. And the setting of the elastic column 344 can further intensify the swing of the oscillating rod 343, obtaining a better cleaning effect.
