However, the steam ejector will generate noise during use. The noise generated by the steam ejector is mainly jet noise and turbulent noise, which is caused by the vortex generated by the high-speed jet ejected from the nozzle and the shear flow of the surrounding gas.

[0031] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.
[0032] A steam ejector device, referring to Figure 1 and Figure 2, including a steam ejector 1, the steam ejector 1 includes a main body 11, a diffusion chamber 12 and an outlet chamber 13 connected in sequence, the main body 11 is connected with an air inlet pipe and an ejector pipe 14, the air inlet pipe is used to pass the gas to be pressurized, and the ejector pipe 14 is used to pass the ejection steam. The steam ejector device also includes a platen 15, the main body 11 is installed on the platen 15, so as to fix the steam ejector 1. In order to reduce the vibration of the ejector pipe 14, a spring hanger is installed on the ejector pipe 14, and the spring hanger is fixedly connected to the ejector pipe 14, so as to reduce the vibration of the ejector pipe 14.
[0033] Reference Figure 2 and Figure 3 The steam ejector device also includes a sound insulation and noise reduction layer 2, which is installed on the steam ejector 1 to soundproof and reduce the noise of the steam ejector 1, and a sound insulation and noise reduction layer 2 is also installed between the table top 15 and the main body 11. By installing the sound insulation and noise reduction layer 2 between the table top 15 and the main body 11, the possibility of noise being transmitted from the main body 11 to the table top and then transmitted through the table top 15 is reduced.
[0034] In this embodiment, the above-mentioned sound insulation and noise reduction layer 2 is arranged on the main body 11, the diffusion chamber 12 and the outlet chamber 13. In other embodiments, the sound insulation and noise reduction layer 2 may be arranged on one of the main body 11, the diffusion chamber 12 and the outlet chamber 13, or on two of them.
[0035] The sound insulation and noise reduction layer 2 includes an ultra-fine glass wool layer 25, a lead plate 26 and a T70 sound insulation layer 24. The T70 sound insulation layer 24 is produced by Maike Company. Sound insulation coil. The T70 sound insulation layer 24, the ultra-fine glass wool layer 25 and the lead plate 26 are sequentially mounted on the steam ejector 1. First, the sound insulation is performed by the T70 sound insulation layer 24, then the sound is absorbed by the ultra-fine glass wool layer 25, and finally the lead plate 26 is used for secondary sound insulation, thereby increasing the sound insulation and noise reduction effect. In addition, the T70 sound insulation material is based on patented micro-nano layered composite technology. The interior of the coil is composed of a multi-layer structure. The sound waves are attenuated by multi-layer reflections when passing through layered interfaces with different characteristic impedances, which effectively changes and avoids the "matching effect" of the material, thereby further increasing the sound insulation and noise reduction effect of the steam ejector 1.
[0036] The sound insulation and noise reduction layer 2 on the table top is formed by stacking two lead plates 26 , two layers of ultra-fine glass wool layers 25 and two layers of T70 sound insulation layers 24 from top to bottom.
[0037] Sound insulation is to block noise, weaken transmitted sound energy, and block the propagation of sound. Sound absorption is to absorb sound, thereby reducing the spread of sound. By first soundproofing, then absorbing sound, and then soundproofing, the effect of sound insulation and noise reduction is greatly increased.
[0038] The thickness of the ultra-fine glass wool is 15cm-20cm. In this embodiment, the thickness of the ultra-fine glass wool is 15cm, and the density is 20KG / m3. The sound absorption coefficients of ultra-fine glass wool and aluminum silicate surface with different thicknesses are shown in the following table:
[0039]
[0040] From the above table, we can see that when ultra-fine glass wool is used and the thickness of the ultra-fine glass wool is 15cm and the density is 20Kg / m 3 When the sound absorption coefficient of noise of each frequency is optimal.
[0041] In the following, the sound insulation and noise reduction layer 2 on the main body 11 is named as the first sound insulation and noise reduction layer 21 , the sound insulation and noise reduction layer 2 on the diffusion chamber 12 is named as the second sound insulation and noise reduction layer 22 , and the sound insulation and noise reduction layer 2 on the outlet chamber 13 is named as the third sound insulation and noise reduction layer 23 .
[0042] Since the noises generated by the body 11, the plenum chamber 12 and the outlet chamber 13 are different in magnitude, in order to reduce the waste of materials, the first sound insulation and noise reduction layer 21, the second sound insulation and noise reduction layer 22 and the third sound insulation and noise reduction layer 23 are all composed of different compositions, as follows: the first sound insulation and noise reduction layer 21 is composed of two layers of T70 sound insulation layers 24, three layers of ultra-fine glass wool layers 25 and one layer of lead plate 26. First, two layers of T70 sound insulation layers 24 are sleeved on the body 11, then three layers of ultra-fine glass wool layers 25 are sleeved, and finally one layer of lead plate 26 is sleeved to complete the sound insulation and noise reduction of the body 11.
[0043] The second sound insulation and noise reduction layer 22 is composed of two layers of T70 sound insulation layers 24, three layers of ultra-fine glass wool layers 25 and two layers of lead plates 26. First, two layers of T70 sound insulation layers 24 are sleeved on the body 11, then three layers of ultra-fine glass wool layers 25 are sleeved, and finally two layers of lead plates 26 are sleeved to complete the sound insulation and noise reduction of the expansion chamber 12.
[0044] The third sound insulation and noise reduction layer 23 is composed of a T70 sound insulation layer 24 and three ultra-fine glass wool layers 25. First, a T70 sound insulation layer 24 is sleeved on the body 11, and then three ultra-fine glass wool layers 25 are sleeved to complete the sound insulation and noise reduction of the outlet chamber 13.
[0045] In this embodiment, in order to further increase the sound insulation and noise reduction effect of the steam ejector 1, adjacent sound insulation and noise reduction layers 2 are overlapped with each other in a staggered manner. Taking the first sound insulation and noise reduction layer 21 and the second sound insulation and noise reduction layer 22 as an example:
[0046] The T70 sound insulation layers 24 on the same layer are abutted against each other, the T70 sound insulation layer 24 on the second layer is overlapped at the overlapping gaps of the adjacent T70 sound insulation layers 24 on the first layer to seal the overlapping gaps, and the ultra-fine glass wool layer 25 on the third layer is overlapped at the overlapping gaps of the adjacent T70 sound insulation layers 24 on the second layer to seal the overlapping gaps. The above layers are overlapped in sequence to further increase the sound insulation and noise reduction effects.
[0047] In order to reduce the overlapping gap between adjacent sound insulation and noise reduction layers 2, a 45° bevel overlap is adopted at the overlapping part. Taking the adjacent T70 sound insulation layers 24 as an example, the end faces of two adjacent T70 sound insulation layers 24 close to each other are set as 45° bevels. When the adjacent T70 sound insulation layers 24 abut against each other, the two bevels fit against each other, thereby reducing the gap caused by the mutual abutment.
[0048] The implementation principle of the embodiment of the present application is: by respectively arranging the first sound insulation and noise reduction layer 21, the second sound insulation and noise reduction layer 22 and the third sound insulation and noise reduction layer 23 on the main body 11, the diffusion chamber 12 and the outlet chamber 13, sound insulation and noise reduction are performed on different parts of the steam ejector 1.
[0049] The noise is first soundproofed by using the T70 sound insulation layer 24, then the noise is sound-absorbed by using the ultra-fine glass wool layer 25, and finally the noise is secondarily soundproofed by using the lead plate 26, thereby increasing the sound insulation and noise reduction effect.
[0050] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
