Description

Technical Field

[0001] The invention relates to the technical field of boiler soot blowers, in particular to a high-frequency sonic soot blower for a boiler. Background Art

[0002] The sonic soot blower technology converts compressed air into high-power sound waves or infrasound waves (a pressure wave that propagates in a spatial medium (gas) in the form of a density wave) and sends it into the furnace. When the ash accumulated on the heated surface is repeatedly pulled and compressed by the density waves that alternate at a certain frequency, it becomes loose and falls off due to fatigue and is carried away by the flue gas flow, or sinks to the ash hopper and is discharged under the action of gravity.

[0003] When using an acoustic sootblower, a compressed air supply is required to activate the acoustic horn. This requires compressed air or an air pump to power the horn, which in turn requires additional piping to connect to the horn, increasing usage and maintenance costs. Therefore, we propose a high-frequency acoustic sootblower for boilers. Summary of the invention

[0004] The purpose of the present invention is to provide a high-frequency ultrasonic soot blower for a boiler, in which the air inside the copper cylinder is expanded by the heat of the boiler, and the heat-resistant rubber membrane is compressed and deformed. After the other side of the cylinder is sealed, the deformed state can be maintained. When soot cleaning is required, the ultrasonic horn is connected to the air box and the seal on the other side of the cylinder is released. The compression effect of the air when the heat-resistant rubber membrane is reset can be utilized to make the air flow pass through the ultrasonic horn to perform soot cleaning. No additional air source is required, which reduces the use cost and maintenance cost, and solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-frequency acoustic soot blower for a boiler, comprising an air box, an air cylinder, an acoustic horn and a copper cylinder; an air outlet pipe communicating with the interior of the air box is provided on the side of the air box, a first electrically-controlled valve is installed on the air outlet pipe, the first electrically-controlled valve is communicated with the air outlet pipe, the air inlet end of the acoustic horn is communicated with the air outlet pipe through the first air pipe, and the copper cylinder is communicated with the interior of the air box through the second air pipe; the air cylinder is connected to the side of the air box, and the side of the air cylinder is communicated with the interior of the air box, a heat-resistant rubber membrane is provided inside the air cylinder, and the heat-resistant rubber membrane is provided inside the air cylinder.

After sealing the left side of the inside of the air cylinder, negative pressure can be used to maintain the deformed state of the heat-resistant rubber membrane. When dust cleaning is required, after releasing the seal on the left side of the inside of the air cylinder, the heat-resistant rubber membrane will rebound to its original position and the compressed air will pass through the sonic horn, causing it to work and achieve the purpose of dust removal.

[0007] As a preferred embodiment of the present invention, the air box is configured to be rectangular, and the air cylinder is provided with multiple communicating connections on the side of the air box.

[0008] By adopting the above technical solution, the multiple heat-resistant rubber membranes of the multiple air cylinders are arranged to provide a better compression effect of the heat-resistant rubber membrane, thereby obtaining a larger amount of compressed air passing through the sonic horn.

[0009] As a preferred embodiment of the present invention, a plurality of copper cylinders are provided, and the plurality of copper cylinders are all connected to the interior of the air box through a second air pipe.

[0010] By adopting the above technical solution, multiple copper cylinders are heated, so that the air inside them can expand further, and the compression deformation effect on the multiple heat-resistant rubber membranes is better.

[0013] As a preferred embodiment of the present invention, a first filter and a second filter are installed on the top of the air intake pipe and the air duct, respectively. The first filter and the second filter are communicated with the air intake pipe and the air duct, respectively.

[0014] By adopting the above technical solution, it is possible to prevent impurities from being brought into the air box or the air cylinder when external air enters.

[0015] As a preferred embodiment of the present invention, filter cotton is embedded and fixed inside the first filter and the second filter, and the tops of the first filter and the second filter are communicated with the outside.

[0016] By adopting the above technical solution, impurities in the air are filtered using filter cotton.

[0017] As a preferred embodiment of the present invention, an observation port is laterally provided on the side surface of the gas cylinder, and heat-resistant glass is embedded and fixed inside the observation port.

[0018] By adopting the above technical solution, it is convenient to observe the compression deformation of the heat-resistant rubber film inside the air cylinder through the observation port at any time.

[0019] As a preferred embodiment of the present invention, a bottom plate is welded and fixed to the bottom side of the air box, and a perforation is provided on the surface of the bottom plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The high-frequency acoustic soot blower for boilers of the present invention is provided with an air cylinder connected to the side of the air box, and a heat-resistant rubber film with good elasticity is fixed inside. A copper cylinder is connected to the inside of the air box and extends into the combustion chamber of the boiler. When the combustion chamber is working, the copper cylinder can absorb heat to cause the air inside to expand and diffuse into the air box and the air cylinder, causing the heat-resistant rubber film to be compressed and deformed. After sealing the other side of the air cylinder, the deformed state can be maintained. When soot cleaning is required, the acoustic horn is connected to the air box and the seal on the other side of the air cylinder is released. The compression effect of the air by the reset of the heat-resistant rubber film can be utilized to enable the air flow to pass through the acoustic horn for soot cleaning work, without the need for additional air source supply, reducing the use cost and maintenance cost.

[0025] 2. The high-frequency acoustic soot blower for boilers of the present invention has the air box set as a cuboid shape and is connected with multiple air cylinders. The arrangement of multiple heat-resistant rubber films in the multiple air cylinders can provide a better compression effect of the heat-resistant rubber film, thereby obtaining a larger amount of compressed air passing through the acoustic horn. Multiple copper cylinders are provided and can be installed in the boiler. When the multiple copper cylinders are heated, the air inside them can expand more, and the compression and deformation effect on the multiple heat-resistant rubber films is better. In addition, multiple auxiliary pipes are connected to the side of the air box to supply air to the multiple acoustic horns to make them work.

[0026] 3. The high-frequency acoustic soot blower for boilers of the present invention is equipped with filters at the ends of the air inlet pipe and the conduit, and filter cotton is provided inside. When external air enters the air box or the air cylinder, impurities can be avoided from being brought in.

[0035] Example 1

[0036] See also Figures 1-3 The present invention provides a technical solution: a high-frequency acoustic soot blower for a boiler, comprising an air box 1, an air cylinder 2, an acoustic horn 3 and a copper cylinder 4; a mounting plate 5 is fixed to the outer ring of the left end face of the acoustic horn 3, and a through hole is provided on the surface of the mounting plate 5. When in use, bolts pass through the through holes through the mounting plate 5 to install and fix the acoustic horn 3, so that the acoustic horn 3 is installed in the boiler that needs to be cleaned. When the acoustic horn 3 is started, the accumulated ash in the boiler is subjected to repeated pulling and pressing actions of density waves that alternately change at a certain frequency, and the accumulated ash is loosened and falls off due to fatigue and is carried away with the flue gas flow, or sinks to the ash hopper for discharge under the action of gravity.

[0037] At the bottom of the side of the air box 1, a bottom plate 12 is fixedly welded. A perforation 121 is formed on the surface of the bottom plate 12. The air box 1 can be placed at the side position of the boiler, so that bolts pass through the perforation 121 to penetrate the bottom plate 12, thereby locking the bottom plate 12 and realizing the installation and fixation of the air box 1.

[0038] The air cylinder 2 is connected to the side of the air box 1, and the right side of the air cylinder 2 is communicated with the inside of the air box 1. A heat-resistant rubber film 21 is arranged inside the air cylinder 2. The whole heat-resistant rubber film 21 is connected to the inner ring of a rubber ring 211. A ring 212 is fixed to the side of the rubber ring 211, and the ring 212 is fixedly welded to the inner wall surface of the air cylinder 2, so that the rubber ring 211 is hermetically attached to and abuts against the inner wall surface of the air cylinder 2, and the heat-resistant rubber film 21 is located at one end of the air cylinder 2 close to the air box 1.

[0039] In addition, a gas guide pipe 23 communicating with its inside is vertically connected above the end of the air cylinder 2 away from the air box 1, and a second electric control valve 231 is installed on the gas guide pipe 23. The second electric control valve 231 is communicated with the gas guide pipe 23. The copper cylinder 4 is communicated with the inside of the air box 1 through a second air pipe 41. At the same time, an installation plate 5 is fixed to the outer ring of the left end face of the sound wave horn 3. Through holes are arranged on the surface of the installation plate 5. When in use, bolts pass through the through holes to penetrate the installation plate 5 to install and fix the copper cylinder 4, and the copper cylinder 4 is inserted and fixed inside the combustion chamber of the boiler. When in use, the inside of the air cylinder 2, the air box 1 and the copper cylinder 4 are all filled with air. When the boiler burns, the high temperature is transmitted to the copper cylinder 4, causing the air inside it to be heated. Since the air expands greatly when heated, heat is also transmitted to the inside of the air box 1 through the second air pipe 41 to make the air expand, pressing the heat-resistant rubber film 21 to the left and deforming it. When the second electric control valve 231 remains open, when the heat-resistant rubber film 21 moves to the left, the air in the air cylinder 2 on the left side of the heat-resistant rubber film 21 is discharged from the conduit to the outside.

[0040] An air inlet pipe 13 communicating with its inside is also connected to the top of the air box 1. A one-way valve 131 is installed on the air inlet pipe 13, and the flow direction of the one-way valve 131 is towards the air box 1. After the heat-resistant rubber film 21 deforms to the left, the second electric control valve 231 is closed to seal the gas guide pipe 23, making the inside of the air cylinder 2 on the left side of the heat-resistant rubber film 21 a sealed structure. Before cleaning the dust inside the boiler, it is necessary to let the boiler cool down naturally first. Then the air in the right side of the heat-resistant rubber film 21, the air box 1 and the copper cylinder 4 will all cool down and reduce in volume. At this time, the external air can enter the inside of the air box 1 through the air inlet pipe 13 and the one-way valve 131 to make the air pressure inside and outside the air box 1 balanced, while the left side of the heat-resistant rubber film 21 is in a negative pressure environment, thus preventing the heat-resistant rubber film 21 from deforming and resetting.

[0041] An air outlet pipe 11 communicating with the inside thereof is provided on the side of the air box 1, and a first electrically controlled valve 111 is installed on the air outlet pipe 11. The first electrically controlled valve 111 communicates with the air outlet pipe 11, and the air inlet end of the acoustic horn 3 is communicated with the air outlet pipe 11 through a first air pipe 31. During the above operation process, the first electrically controlled valve 111 remains in a closed state. When the boiler is cooled in place and soot blowing and cleaning are required, the first electrically controlled valve 111 and the second electrically controlled valve 231 are opened simultaneously. Air can enter the left side inside of the air cylinder 2 through the air guide pipe 23, so as to balance the air pressure on both sides of the heat-resistant rubber film 21. The heat-resistant rubber film 21 will quickly reset to the right under the action of its elasticity, and the air will be compressed to the right. Since the one-way valve 131 on the air inlet pipe 13 only allows air to flow downward, the air will not be discharged from the air inlet pipe 13, but will enter the acoustic horn 3 through the second air pipe 41, causing the acoustic horn 3 to work for soot blowing.

[0042] When the external air enters the inside of the air box 1 from the air inlet pipe 13 during the temperature drop, the external air will enter the inside of the air box 1 from the air inlet pipe 13. At this time, it is easy to bring in external dust into the air box 1. To solve this problem, a first filter 132 is installed on the top of the air inlet pipe 13. The first filter 132 communicates with the air inlet pipe 13, and a filter cotton 6 is embedded and fixed inside the first filter 132. The upper part of the first filter 132 communicates with the outside. When the external air passes through the first filter 132, it will be filtered to avoid impurities from entering the inside of the air box 1.

[0043] When the heat-resistant rubber film 21 deforms and resets to the right, the external air will enter the left side inside of the air cylinder 2 from the air guide pipe 23. At this time, it is easy to bring in external dust into the air cylinder 2. To solve this problem, a second filter 232 is installed on the top of the air guide pipe 23. The second filter 232 communicates with the air guide pipe 23, and a filter cotton 6 is embedded and fixed inside the second filter 232. The upper part of the second filter 232 communicates with the outside. When the external air passes through the second filter 232, it will be filtered to avoid impurities from entering the left side inside of the air cylinder 2.

[0044] In addition, an observation port 22 is horizontally arranged on the side surface of the air cylinder 2, and a heat-resistant glass 221 is embedded and fixed inside the observation port 22. When the heat-resistant rubber film 21 is pushed and deformed by the air, the deformation condition of the heat-resistant rubber film 21 can be observed at any time through the observation port 22, which is convenient to close the second electrically controlled valve 231 on the air guide pipe 23 in a timely manner at an appropriate time.

[0045] Embodiment 2

[0046] The presence of a single air cylinder 2 and a single heat-resistant rubber membrane 21 may lead to a limited amount of air compression in the subsequent process, and thus the working duration of the acoustic horn 3 is insufficient. To solve this problem, another embodiment is proposed in this application. Please refer to Figure 4 and Figure 5 , and the other structures are the same. Among them, the air box 1 is set to be rectangular, and a plurality of air cylinders 2 are connected to the side of the air box 1 in a communicating manner, so that a plurality of heat-resistant rubber membranes 21 can be compressed and deformed to the left, and more air can be compressed into the air box 1 on the right when resetting later.

[0047] However, through the above settings, there will still be a problem that a single copper cylinder 4 is heated and cannot expand the air to a greater extent to make all the heat-resistant rubber membranes 21 deformed to the left in place. For this reason, in this embodiment, a plurality of copper cylinders 4 are also provided, and the plurality of copper cylinders 4 are all connected to the inside of the air box 1 through the second air pipe 41, so that they can be better heated to make more air expand enough to make all the heat-resistant rubber membranes 21 compressed and deformed in place.

[0048] In addition, in order to achieve the purpose of efficient soot blowing and cleaning, a plurality of acoustic horns 3 may also be used. Therefore, a plurality of auxiliary pipes 14 communicating with the inside are also connected to the side of the air box 1 in this embodiment. A first electric control valve 111 is installed on the auxiliary pipe 14 to supply air to a plurality of acoustic horns 3 at the same time to make them work. And a auxiliary valve 141 is also installed on the auxiliary pipe 14 on the side of the first electric control valve 111, and the used auxiliary pipe 14 can be sealed by closing the auxiliary valve 141.

[0049] In use, the copper cylinder 4 is installed in the combustion chamber of the boiler through the mounting plate 5, and the acoustic horn 3 is also installed at the position in the boiler where soot blowing is required regularly through the mounting plate 5. The air box 1 and the air cylinder are placed beside the boiler and are locked through the bottom plate 12 and the perforations 121 on its surface in cooperation with bolts. The first electric control valve 111 and the second electric control valve 231 are both connected to the industrial control computer. In use, when the boiler starts to operate, the first electric control valve 111 is kept closed and the second electric control valve 231 is opened. The copper cylinder 4 will be heated, and the air inside it will be heated and expanded. Since the first electric control valve 111 is in the closed state and the one-way valve 131 can prevent the air from discharging outward from the air inlet pipe 13, the air in the air box 1 will expand and diffuse into the air cylinder 2, causing the heat-resistant rubber membrane 21 to be deformed by being pushed to one side of the guide pipe 23, and the air inside the air cylinder 2 on the side far from the air box 1 will be discharged outward through the guide pipe 23. During this process, the deformation of the heat-resistant rubber membrane 21 can be observed through the observation port 22. When the deformation reaches a sufficient degree, the second electric control valve 231 is closed, making the left side of the air cylinder 2 in a sealed state. When the boiler needs to be ash-cleaned inside, the boiler operation needs to be stopped first, and then the air in the boiler combustion chamber will cool down. When the air temperature inside the air box 1 and the right side of the air cylinder 2 decreases, its volume will decrease, and then external air can be supplemented into the air box 1 and the right side of the air cylinder 2 through the first filter 132 and the air inlet pipe 13. The inside of the air cylinder 2 on the left side of the heat-resistant rubber membrane 21 is in a sealed negative pressure state, which can keep the heat-resistant rubber membrane 21 in a state of bulging to the left. When the boiler cools down to a temperature suitable for soot blowing and cleaning, the first electric control valve 111 and the second electric control valve 231 are opened simultaneously. Air can enter the left side of the air cylinder 2 through the guide pipe 23, so as to balance the air pressure on both sides of the heat-resistant rubber membrane 21. The heat-resistant rubber membrane 21 will quickly reset to the right under the action of its elasticity, and the air will be compressed to the right and enter the acoustic horn 3 through the second air pipe 41, making it emit sound waves into the furnace. When the ash deposited on the heating surface is repeatedly pulled and pressed by the density waves that alternate at a certain frequency, it will fall off due to fatigue and looseness, achieving the purpose of ash cleaning.
