The vibration of the silencer chamber 1 can be reduced by the contraction and rebound of the damper 22 and the spring 23, thereby improving its stability. The anti-slip pad 24 can increase the friction force to prevent the silencer chamber 1 from shaking and tipping over due to vibration.

[0026] The working principle of this embodiment is as follows: when in use, first start the water pump 16, draw in the external water source connected to the external pipe 17, and transport it to the inside of the muffler chamber 1 through the water inlet pipe 18, then the steam enters the inside of the diverter pipe 12 from the steam inlet pipe 13, and flows to the cover plate 6 through the connecting pipe 14, and the steam passes through the muffler liner 5 and the muffler shell 4 through the small holes to disperse and reduce the noise. At the same time, the steam can heat the water inside the muffler chamber 1, and the remaining noise will be further absorbed and reduced by the sound-absorbing gravel layer 3 and the sandstone sound-absorbing board 9, so as to achieve the purpose of sound absorption and noise reduction. Finally, open the valve 20 to allow the hot water in the muffler chamber 1 to be discharged from the drain pipe 19, thereby completing the use of the high-performance rock muffler device for the steam system of the power plant.
