The operation principle of the utility model is described as follows below：
There are section relationships for the sense of hearing of human ear and the frequency of sound, and the sound frequency section that can be heard under normal circumstances is
The sound of 1000~20000Hz, high frequency and low frequency by people all to will not be heard, according to this characteristic, when muffler designs
It needs that intermediate frequency noise is reduced or improved by certain measure and method, the first order and two level drop in the present apparatus
The measure of making an uproar is to reduce noise by the way that sound frequency is increased to audible frequency or more, and three-level noise reduction is by reducing sound frequency
Noise is reduced below to audible frequency.
The sound frequency of high steam is related with the speed of exit steam and caliber, and relational expression is as follows：
F=sh × M/d (1)
Wherein：F is sound frequency, and sh Strouhal numbers, M is the muzzle velocity of steam, and d is the diameter of steam (vapor) outlet.
Sound frequency will improve when can show that steam (vapor) outlet speed improves, caliber reduces from formula (1), and frequency is increased to audible frequency
It more than rate will effectively reduce noise content.
When utility model works, steam is entered by steam inlet in level-one silencing cavity first, and silencing means is by cylinder
Cavity and exhaust hole composition, steam entry port are discharged by aperture, and discharge diameter d is rapidly reduced, and f is caused rapidly to be promoted, and is reached
Realize that sound frequency is significantly larger than audible frequency, realizes level-one noise reduction to a certain degree.Simultaneously three-level noise reduction water tank cooling water into
Enter in level-one muffler chamber the first layer cooling, it can be achieved that high-temperature steam.And then steam enters two level by level-one silencing cavity and disappears
Sound chamber, two level silencing cavity is roughly the same with level-one noise reduction cavity configuration, is made of circular cylindrical cavity and aperture, and steam is discharged from aperture
Diameter d is reduced, and f is rapidly promoted, it can be achieved that two level noise reduction, similarly, three-level noise reduction cooling water carry out secondary cooling to steam；When from
After the discharge of two level silencing cavity, high steam is condensed into liquid water stream and enters in three-level noise reduction sink mostly, big due to having in sink
The liquid water of amount to will constantly be reduced to flow velocity M, and then is discharged from tertiary effluent groove upper cap plate hole, and d is rapidly promoted, to real
The rapidly reduction of existing frequency f, reaches a certain level achievable frequency and is less than audible frequency, to realize third level noise reduction.Pass through
Three-level noise reduction realization noise is greatly lowered, and is worker's physical and mental health and unit to build good comfortable working environment
Safety in production provides a strong guarantee.
The utility model has the following technical effect that：
1, effective reduction of high pressure vapor line exhaust noise is realized.
2, Aided design can be carried out with original pipeline.
3, simple in structure, be easy to make and installation.
4, cooling and drainage can be realized to outlet high steam, prevents dangerous accident from occurring.
5, excessive maintaining is not necessarily to after installing.
