Boiler blowing is an operation method of blowing steam into the steam pipe to achieve the purpose of cleaning and pollution-free. Boiler blowing will generate a lot of noise during operation. At this time, a noise reduction silencer will be needed to reduce the noise generated by the blowpipe.

[0004] In the process of using the noise reduction silencer, the inventor found that there are at least the following problems in the existing technology that have not been solved: 1. Although the traditional silencer can achieve a good noise reduction and silencing effect, and often uses a porous silencer tube combined with sound-absorbing materials to achieve noise reduction and silencing, the resistance caused by the flow of gas inside the silencer will consume a certain amount of energy, especially in a high temperature and high pressure environment, which will cause the internal temperature of the silencer to rise, thereby increasing the energy consumption of the silencer, and cannot achieve a good energy-saving effect. 2. The silencer structure of most silencers, after a long period of use, and when used in a relatively high temperature environment such as a boiler, especially the sound-absorbing structure therein, such as rock wool board, pearl cotton board and other structures, will age and the noise reduction effect will deteriorate, which is inconvenient for staff to inspect and replace it. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0022] The present invention is further described below with reference to the accompanying drawings and embodiments:
[0023] Example 1: An energy-saving noise-reducing muffler for boiler blowpipe, see Figures 1 to 6 , including a muffler body 1, the interior of the muffler body 1 is fixedly connected to a heat conducting plate 10, the other end of the heat conducting plate 10 is respectively sleeved with a third through-hole tube 19, a second through-hole tube 18 and a first through-hole tube 17, and a reinforcing plate 9 is used to connect the first through-hole tube 17, the second through-hole tube 18 and the third through-hole tube 19. Since the reinforcing plate 9 is used to connect the first through-hole tube 17, the second through-hole tube 18 and the third through-hole tube 19, the connection strength between the three is well improved, and looseness and shaking will not easily occur during use; the interior of the first through-hole tube 17 is fixedly connected to the diverter plate 14, and a central column 20 is provided at the center of the diverter plate 14. Due to the four diverter plates 14, a large amount of airflow can be diverted. The airflow is diverted to form four new small airflows, thereby achieving a further noise reduction effect; a heat sink 12 is fixedly embedded on the outside of the muffler body 1, and the heat sink 12 and the heat conducting plate 10 are in contact with each other. A heat sink 13 is provided on the side of the heat sink 12. In this way, when in use, the heat conducting plate 10 is combined with the heat dissipation and heat sink 13 provided on the outside of the muffler body 1. In this way, when the inside of the muffler generates a higher temperature due to the high-temperature gas, the high temperature can be transferred to the muffler body 1 through the heat conducting plate 10, and the heat dissipation is quickly performed by the heat sink 12 outside the muffler body 1 and the multiple heat sinks 13 on the heat sink 12, so as to reduce the high temperature inside the muffler and achieve the effect of energy saving and noise reduction.
[0024] For details, see Figure 3 A top cover 4 is provided on the top of the muffler body 1, a fixing ring 6 is welded on the top of the muffler body 1, and the top cover 4 is embedded inside the fixing ring 6. By providing a protruding fixing ring 6 on the top of the muffler body 1, the top cover 4 can be embedded, thereby improving the tightness and sealing performance of the connection.
[0025] For further information, see Figures 1 to 5The top of the top cover 4 is provided with an internal threaded seat 5, and a through-hole 15 is provided on the surface of the fixing ring 6. The internal threaded seat 5 and the fixing ring 6 are connected by a fastening bolt 7. The fastening bolt 7 passes through the through-hole 15, and the rock wool sound-absorbing panel 16 is inserted into the interior of the muffler body 1. The rock wool sound-absorbing panel 16 is clamped on the outside of the heat conducting plate 10. There are four rock wool sound-absorbing panels 16. An independent top cover 4 is provided on the top of the muffler body 1, and a fixing ring 6 is installed on the top of the muffler body 1, and a fastening bolt 7 is used to connect and fix the top cover 4 and the fixing ring 6. As the muffler is used for a long time, the rock wool sound-absorbing panel 16 inside it ages due to long-term use. When the sound absorption effect deteriorates, the top cover 4 can be disassembled separately, the old rock wool sound-absorbing panel 16 inside the muffler body 1 is taken out, and a new rock wool sound-absorbing panel 16 is replaced, so as to achieve the purpose of maintenance and replacement, which is more convenient to operate.
[0026] It is worth noting that, see Figure 1 The top of the top cover 4 is fixedly connected to the discharge pipe 8, and the discharge pipe 8 and the muffler body 1 are interconnected. There are four groups of internal threaded seats 5. Through the four groups of internal threaded seats 5, the top cover 4 and the fixing ring 6 can be better connected, which is more practical.
[0027] It is worth noting that see Figure 2 and Figure 6 One end of the heat conducting plate 10 is sleeved with a sealing ring 11, and the sealing ring 11 is attached to the inner wall of the first through-hole tube 17. The heat conducting plate 10 is distributed in an annular form. The sealing ring 11 structure can better ensure the sealing performance of the four spaces inside the muffler.
[0028] It is worth mentioning that see Figure 2 The bottom of the muffler body 1 is fixedly connected to the bottom plate 21. A connecting pipe 2 is provided on the outside of the bottom plate 21. The other end of the connecting pipe 2 is fixedly connected to the flange 3. The connecting pipe 2 and the interior of the muffler body 1 are connected to each other. Through the flange 3 structure, the muffler can be conveniently installed on the end of the boiler blowpipe, which is more convenient to operate.
[0029] When using the energy-saving noise reduction silencer, you first need to install the silencer, install the flange 3 at the bottom and the end mounting position of the boiler blowpipe, and use fasteners to connect and fix them. Then, when the airflow enters the silencer, it will first pass through the diverter plate 14 set inside the silencer body 1, which can divide an airflow into four airflows. Then, when the four airflows diffuse again, they are dispersed and weakened by the first through-hole tube 17, the second through-hole tube 18 and the third through-hole tube 19. Then, the rock wool sound-absorbing panel 16 wrapped around the outside of the third through-hole tube 19 absorbs the sound, thereby achieving the effect of noise reduction and silencing. At the same time, during the operation of the silencer, due to the combination of the heat conduction plate 10 installed inside the silencer body 1 and the heat dissipation and heat sink 13 provided on the outside of the silencer body 1, when the inside of the silencer generates a higher temperature due to the high-temperature gas, the high The temperature can be conducted to the muffler body 1 through the heat conducting plate 10, and the heat is quickly dissipated by the heat dissipation plate 12 outside the muffler body 1 and the multiple heat dissipation fins 13 on the heat dissipation plate 12, so as to reduce the high temperature inside the muffler, thereby reducing the energy consumption of the muffler, achieving the effect of energy saving and noise reduction, and effectively improving the service life of the noise reduction muffler. In addition, as the use time of the muffler increases, since an independent top cover 4 is installed on the top of the muffler body 1 and a fixing ring 6 is installed on the top of the muffler body 1, when the rock wool sound absorbing board 16 inside it ages and the sound absorption effect deteriorates due to long-term use, the top cover 4 can be removed separately, and then the rock wool sound absorbing board 16 can be pulled out from the inside of the muffler body 1 and replaced with a new rock wool sound absorbing board 16, so as to achieve the purpose of maintenance and replacement, which is more convenient during operation.
