At the boiler site, when there are urgent matters that need to be communicated, the sound of boiler exhaust causes certain troubles to the workers and makes communication between workers inconvenient. Utility Model Content

[0003] In order to reduce the noise of boiler exhaust, the utility model provides a steam boiler silencer.

[0004] The utility model provides a steam boiler silencer adopting the following technical solutions:

[0005] A steam boiler silencer comprises an outer shell, support ribs and an inner tube, wherein the outer surface of the inner tube is fixedly connected to the interior of the outer shell via the support ribs, one end of the inner tube is located inside the outer shell, and the other end of the inner tube is exposed to the outside of the outer shell, three partitions are fixedly connected to the interior of the inner tube, a sound-absorbing cavity is defined between the outer shell and the inner tube, and a metal mesh layer is plugged into the interior of the sound-absorbing cavity.

[0006] By adopting the above technical solution, the part of the inner tube that leaks out of the outer shell is connected to the exhaust end of the boiler, so that the gas from the boiler enters the inner tube and then enters the sound-absorbing cavity between the outer cylinder and the inner tube. The gas is continuously reflected inside the inner tube to form a gas vortex, and after consuming a certain amount of energy, it passes through the metal mesh layer in the sound-absorbing cavity. The metal itself can absorb heat or resonate with sound. The metal mesh layer absorbs the energy in the gas, thereby cooling, reducing the pressure and speed of the gas, and then reducing noise when it is discharged through the exhaust pipe.

[0007] Preferably, the metal mesh layer includes a spiral skeleton and a plurality of metal wires, and the plurality of metal wires are all wound around the outer surface of the spiral skeleton.

[0008] By adopting the above technical solution, metal wire is cheap and easy to obtain compared with other sound-absorbing materials. When the waste heat of boiler gas is high, the sound-absorbing material and metal wire are easily carbonized into slag, which is more economical for repairing metal wire.

[0009] Preferably, the inner tube is divided into four reflecting cavities by three partitions, the four reflecting cavities are arranged linearly, and one of the reflecting cavities is connected to the interior of the sound absorbing cavity.

[0010] By adopting the above technical solution, the gas flows upward from the lowest reflective cavity until it flows from the uppermost reflective cavity to the inside of the sound-absorbing cavity, and then absorbs sound and heat through the metal mesh layer, consuming the energy of the gas, reducing the speed of the gas, and thus reducing noise.

[0011] Preferably, a ventilation pipe is fixedly connected to the interior of each of the three partitions, and the three ventilation pipes are arranged nonlinearly.

[0012] By adopting the above technical solution, after the gas enters the inner tube, it passes through three ventilation pipes that are not on the same vertical line, and then enters different reflection cavities in different directions, thereby dissipating the kinetic energy of the gas and reducing the noise caused by the gas.

[0013] Preferably, the shell includes an outer cylinder and two seals, the two seals are fixedly connected to the top end and the bottom end of the outer cylinder respectively, and one end of one of the seals is fixedly connected to a discharge pipe.

[0014] By adopting the above technical solution, the gas discharged from the boiler enters the inner tube and is discharged from the outer shell through the discharge pipe. The discharge pipe is located at the bottom end of the outer shell, which is conducive to extending the gas travel path, allowing the gas to pass through more metal mesh layers and be absorbed by the metal mesh. Energy, thereby achieving the effect of cooling and deceleration and reducing noise.

[0015] Preferably, four supports are fixedly connected to the outer surface of the outer cylinder, and the supports include a side plate, a bottom plate and two rib plates, one side of the two rib plates are fixedly connected to one side of the side plate, the bottoms of the two rib plates are fixedly connected to the top of the bottom plate, and a through hole is opened inside the bottom plate.

[0016] By adopting the above technical solution, the outer cylinder is connected to the surrounding fixing frames through the supports, so that the entire shell is vertically connected to the exhaust end of the boiler, thereby silencing the gas discharged from the boiler.

[0017] In summary, the present invention has the following beneficial technical effects:

[0018] 1. This device is equipped with a metal mesh layer. The part of the inner tube that leaks out of the outer shell is connected to the exhaust end of the boiler, allowing the boiler gas to enter the inner tube and then enter the sound-absorbing cavity between the outer cylinder and the inner tube. The gas is constantly reflected inside the inner tube, forming a gas vortex, consuming a certain amount of energy, and then passes through the metal mesh layer in the sound-absorbing cavity. The metal itself can absorb heat or resonate with the sound. The metal mesh layer absorbs the energy in the gas, thereby cooling the gas, reducing its pressure and speed. When the gas is discharged through the exhaust pipe, the noise is reduced.

[0019] 2. This device is equipped with three baffles and four reflective cavities. The gas flows upward from the lowest reflective cavity until it flows from the uppermost reflective cavity into the sound-absorbing cavity. When passing through different reflective cavities, the paths are inconsistent, causing some gas to rise directly to the upper reflective cavity, while the other part of the gas will be reflected by the baffles and collide with the new gas from below, reducing their kinetic energy, thereby consuming the total energy of the gas, reducing the gas speed, and thus reducing noise;

[0020] 3. The device is provided with a spiral skeleton and a metal wire. The metal wire is wound around the outer surface of the spiral skeleton. The spiral skeleton prevents the metal wire from being impacted by the gas and accumulating to the bottom, thereby preventing the metal wire from clogging the bottom of the shell and clogging the discharge pipe. Similarly, when the metal wire needs to be replenished, it is only necessary to pull out the spiral skeleton and put in a new wound spiral skeleton. The metal wire is in an extruded state when entering the shell. After entering the sound-absorbing cavity, the metal wire rebounds and immediately fills the inside of the sound-absorbing cavity, which is convenient for quickly replenishing the metal wire and avoiding a reduction in the use effect of the silencer.

[0030] The following is combined with Figure 1-5 The utility model is described in further detail.

[0031] The embodiment of the utility model discloses a steam furnace silencer.

[0032] Reference Figure 1 、 3 , 4, 5, includes an outer shell 1, support ribs 9 and an inner tube 2, the outer shell 1 is fixedly connected to the support ribs 9, and then connected to the inner tube 2 through the support ribs 9, the outer surface of the inner tube 2 is fixedly connected to the inside of the outer shell 1 through the support ribs 9, one end of the inner tube 2 is located inside the outer shell 1, and the other end of the inner tube 2 is exposed to the outside of the outer shell 1, three partitions 3 are fixedly connected to the inside of the inner tube 2, a sound-absorbing cavity is opened between the outer shell 1 and the inner tube 2, the part of the inner tube 2 leaking out of the outer shell 1 is connected to the exhaust end of the boiler, so that the gas of the boiler enters the inside of the inner tube 2, and then enters the sound-absorbing cavity between the outer cylinder 11 and the inner tube 2, the inside of the sound-absorbing cavity is plugged with a metal mesh layer 4, the gas passes through the metal mesh layer 4 in the sound-absorbing cavity, and is discharged through the discharge pipe 7.

[0033] Reference Figure 1 、 3 , 4, 5, the metal mesh layer 4 includes a spiral skeleton 41 and a plurality of metal wires 42, and the plurality of metal wires 42 are all wound around the outer surface of the spiral skeleton 41. The spiral skeleton 41 is similar to a spring as a whole, and the metal wires 42 are wound around it. The metal wires 42 are elastically filled to fill the sound-absorbing cavity, thereby forming a metal mesh to absorb sound. The spiral skeleton 41 prevents the metal wires 42 from being impacted by the gas and accumulating to the bottom of the shell 1, thereby preventing the metal wires 42 from clogging the bottom of the shell 1 and clogging the exhaust pipe 7. Similarly, when the metal wires 42 need to be replenished, it is only necessary to pull out the spiral skeleton 41 and put in a new wound spiral skeleton 41. The metal wires 42 are in an extruded state when entering the shell 1. After entering the sound-absorbing cavity, the metal wires 42 rebound and immediately fill the sound-absorbing cavity, which is convenient for quickly replenishing the metal wires 42 and avoiding a reduction in the use effect of the silencer.

[0034] Reference Figure 4 、 5 The inner tube 2 is divided into four reflecting cavities 5 by three partitions 3. The four reflecting cavities 5 are arranged linearly. The number of partitions 3 is different. The partitions 3 can also be in the shape of an inverted bowl, an arc plate or other special-shaped partitions 3. The gas is guided to form a vortex along the periphery of the partition 3, and after reducing the pressure of the gas, it is discharged into the atmosphere through the metal mesh layer 4.

[0035] Reference Figure 4 、 5One of the reflecting cavities 5 is connected to the interior of the sound-absorbing cavity. After the gas rises to the uppermost sound-absorbing cavity, it is reflected by the head 12 and guided into the sound-absorbing cavity and the uppermost reflecting cavity 5. The gas entering the sound-absorbing cavity is discharged through the metal mesh layer 4, and the gas entering the reflecting cavity 5 is counteracted by the new gas, creating a certain gas turbulence, reducing the kinetic energy carried by the gas, and reducing the speed of the gas flow.

[0036] Reference Figure 3 、 4 5. A ventilation pipe 6 is fixedly connected to the inside of each of the three partitions 3. The three ventilation pipes 6 are arranged nonlinearly and are not on the same vertical line. As a result, each time the gas passes through a partition 3, it is divided into two parts. One part of the gas enters the ventilation pipe 6 and moves upward, and the other part of the gas touches the partition 3 and is reflected back and collides with the newly entered gas, eliminating a certain amount of kinetic energy, thereby achieving a deceleration effect and reducing the noise of gas emissions.

[0037] Reference Figure 2 The shell 1 includes an outer cylinder 11 and two heads 12, which are respectively fixedly connected to the top and bottom ends of the outer cylinder 11. One end of one of the heads 12 is fixedly connected to a discharge pipe 7, which is located on the head 12 at the bottom end of the shell 1. The gas and carbonized metal wire 42 debris leave the interior of the shell 1 through the discharge pipe 7. The discharge pipe 7 can be a tee pipe or other style of gas pipe to stagger the outlets of the gas and the metal wire 42.

[0038] Reference Figure 1 、 2 The outer surface of the outer cylinder 11 is fixedly connected with four supports 8, and the supports 8 are fixed in the middle of the outer cylinder 11 to prevent the top and bottom ends from vibrating too strongly after the gas is introduced into the outer shell 1.

[0039] Reference Figure 1 、 2 The support 8 includes a side plate 81, a bottom plate 82 and two ribs 83. One side of the two ribs 83 is fixedly connected to one side of the side plate 81, and the bottoms of the two ribs 83 are fixedly connected to the top of the bottom plate 82. A through hole is opened inside the bottom plate 82, and bolts or other connecting parts are placed in the through hole to connect with the surrounding building fixings, thereby firmly placing the shell 1 on the exhaust end of the boiler.

[0040] The implementation principle of a steam boiler silencer according to the embodiment of the utility model is as follows:

[0041] The part of the inner tube 2 that leaks out of the outer shell 1 is connected to the exhaust end of the boiler, so that the gas from the boiler enters the inner tube 2, and then enters the sound-absorbing cavity between the outer cylinder 11 and the inner tube 2. The gas forms a gas vortex through continuous reflection and collision inside the reflection cavity 5. After consuming a certain amount of energy, it passes through the metal mesh layer 4 in the sound-absorbing cavity. The metal itself can absorb heat or resonate with sound. The metal mesh layer 4 absorbs the energy in the gas, thereby cooling, reducing the pressure and speed of the gas, and then reducing noise when it is discharged through the exhaust pipe 7.
