Product Description

I. Overview 
The steam muffler series products can be used to effectively muffle steam and other gas muffler emissions in municipal, electric power, petroleum, chemical, metallurgical, textile, cement, environmental protection and other industries. It is an important measure to eliminate steam emission noise. For example: steam boilers, steam pipes, safety valves, superheaters, reheaters, deaerators, steam turbines, steam drums, safety doors, autoclaves, pressure kettles and other equipment for steam emission noise reduction and noise reduction. When the user installs Lianyungang Zhuli machinery products as required, the sound attenuation can reach 30-90 decibels.

2. Principle
The steam muffler is mainly based on the principle of "small hole injection" combined with "impedance expansion and sound absorption". Steam discharge generally has a fast flow rate and high flow noise. It is necessary to expand the flow with through holes first. The steam after multiple through holes will get a pressure drop in the resistant expansion chamber, and the airflow will be ejected through the small holes. The sound power of the octave band has been reduced, and the frequency of the sound pressure level has been pushed up to the range above 20000 Hz, and the noise is greatly weakened, but the secondary noise of some frequencies needs to be further muffled. We install a resistive absorption outside the expansion The acoustic cotton structure is designed according to the spectral characteristics of the residual noise emitted by the pressure reducing body to effectively absorb the residual noise.
