Problems solved by technology

[0003] Boiler steam in the power generation department not only has high temperature and high pressure, but also has a wide frequency bandwidth of discharge. It is not enough to rely solely on small holes for noise reduction, and the pressure is too high. Installing sound-absorbing cotton directly at the exhaust port will easily cause damage to the sound-absorbing cotton, and it will not be effective after damage. The effect of cushioning

Embodiment 1

[0032] see figure 1 and figure 2 As shown, the purpose of this embodiment is to provide a multi-functional environmental protection and energy-saving muffler, including a silencing pipe fitting 100, and the silencing pipe fitting 100 includes an outer shell 110, and the two ends of the outer shell 110 are respectively provided with a seal 140 and a cover 160, and the outer shell 110 A central tube 130 is provided on one side of the sealing member 140. The sealing member 140 includes an outer sealing plate 141 and an inner sealing plate 142. The outer sealing plate 141 and the inner sealing plate 142 are connected to form a seal facing the outer casing 110 and is located on the central tube 130. The inner tube 120 is also arranged in the outer shell 110, the inner tube 120 is connected with the central tube 130, and an air outlet cavity is formed between the inner tube 120 and the outer shell 110, please refer to figure 2 As shown, A is the deceleration chamber, B is the dec...

Embodiment 2

[0035] see image 3 As shown, a sound-absorbing layer 180 is provided inside the outer casing 110, and the sound-absorbing layer 180 surrounds the outside of the air outlet cavity, and the sound-absorbing layer 180 is filled with a resistive sound-absorbing structure, which includes glass cloth and sound-absorbing cotton, wherein the glass cloth adopts no Alkali glass cloth and sound-absorbing cotton adopt centrifugal glass wool board. In addition, the cover 160 includes an inner cover 161 and an outer cover 162. The cover plate 162 has a ring structure, and the inner cover plate 161 has a circular structure. An opening is formed between the inner cover plate 161 and the outer cover plate 162. Therefore, when the high-temperature and high-pressure gas enters the deceleration chamber and the decompression chamber, and then passes through the outlet chamber Glass cloth and sound-absorbing cotton absorb the remaining noise after deceleration and decompression, specifically design...

Embodiment 3

[0039] see Figure 5 and Figure 6As shown, the outer wall of the inner tube 120 is provided with a plurality of 121, and the outer wall of the central tube 130 is provided with a plurality of inner tube holes and central tube holes 131, wherein a is the opening area of ​​the inner tube hole central tube hole 131, and the distance between the centers of the holes is is 16mm, and the hole diameter is 3mm; b is the opening area of ​​121, the hole center distance is 16mm, and the hole diameter is 3mm; the section of a and b is 1100mm, so the high temperature and high pressure gas passes through 121 between the deceleration chamber and the decompression chamber flow, and flow out from the central tube 130 through the central tube hole 131 of the inner tube hole, thereby reducing the sound power of each octave band of the flowing high-temperature and high-pressure gas through 121 and the central tube hole 131 of the inner tube hole, so that the frequency of the sound pressure level...

Abstract

The invention relates to a silencing pipe fitting, in particular to a multifunctional environment-friendly energy-saving silencer. The silencer comprises a silencing pipe fitting, the silencing pipe fitting comprises an outer shell, an inner pipe is further arranged in the outer shell and connected with a center pipe, an air outlet cavity is formed between the inner pipe and the outer shell, an opening is formed in the position, corresponding to the air outlet cavity, of a cover piece, high-temperature and high-pressure air enters from a speed reduction cavity formed in the center pipe; in addition, a pressure reduction cavity is formed in the inner pipe; high-temperature and high-pressure gas after speed reduction enters the pressure reduction cavity along the central pipe, and the outer wall of the inner pipe is communicated with the air outlet cavity. After high-temperature and high-pressure gas is subjected to speed reduction and pressure reduction through the speed reduction cavity and the pressure reduction cavity, the generated impact force is greatly reduced, so that when the high-temperature and high-pressure gas subjected to pressure reduction and speed reduction is subjected to buffering and noise reduction through the noise reduction cotton, the noise reduction cotton cannot be damaged by the high-temperature and high-pressure gas, and the problem that the noise reduction cotton is easily damaged due to the fact that the noise reduction cotton is directly arranged at the exhaust port is solved.

Description

technical field [0001] The invention relates to a sound-absorbing pipe fitting, in particular to a multifunctional environment-friendly and energy-saving silencer. Background technique [0002] Chinese Patent Publication No.: CN206176329U discloses a noise reduction device for a boiler exhaust port, which includes a noise reduction shell arranged at the boiler exhaust port, and a guide that communicates with the boiler exhaust port is also arranged on the noise reduction shell. The inner wall of the sound-absorbing shell is fixed with a layer of sound-absorbing material, and a deflector made of sound-absorbing material is fixed in the position facing the exhaust port of the boiler in the sound-absorbing shell. Noise-absorbing cotton, when the smoke is discharged, it is buffered by the noise-absorbing cotton, and the speed is quickly reduced, and then discharged through the muffler device to reduce noise. [0003] Boiler steam in the power generation department not only has ...
