Silencer for steam flowing out

The innovation concerns a silencer for outflow Steam with an entrance space formed by perforated side walls and containing packing.

In steam operating equipment, especially in those that work in counter-pressure or compound circuit, comes it often happens that with partial or total throttling of the steam consumption still relatively high tension and overheated Steam must be blown off into the open. This is usually associated with a lot of noise, both in your own company and

is also perceived as annoying and unpleasant in the neighborhood,

In order to remedy this problem, it was proposed that the steam be fed through a cylinder consisting of several sheet metal provided with concentric and offset holes Conduct muffler. The task at hand is only incompletely achieved because of the steam Damper still leaves with relatively high pressure.

It is also known to use the muffler in internal combustion engines to fill with spherical bodies, which are moved by the escaping gas, so that the gas pressure decreases. The usage such a muffler for steam to be blown off under high pressure is obviously relative because of the high price of the spherical body has not been envisaged.

For the same reason, silencers intended for internal combustion engines, in which prefabricated spherical, with axial bores provided bodies or tubes made of ceramic material are used as a filler, when Steam blow-off not used.

The object of the innovation is to create an economical and effective one while avoiding the disadvantages described To create silencers for outflowing steam. It will therefore

suggested a relaxation pot, which was completed at the forehead end is and at the other end a steam inlet opening has to use, the openwork jacket of a completely filled with granular material, in particular gravel Ringrauia is enclosed.

In the expansion pot according to the fire, the pressure energy is of the steam entering due to the widening of the cross section and the deflection by 90 ° and the resulting turbulence significantly reduced, so that the steam enters the gravel filling with significantly reduced flow energy. the granular gravel filling sets the energy of the flowing through Steam further down and it is easy to understand that the granular material has the effect of smooth spheres or smoother, rounded pebbles far outperforms, and also the greater economic efficiency of the granular gravel used according to the innovation in contrast to the expensive spherical gravel Particular emphasis should be placed on damping bodies. The gravel layer offers the steam flow a multitude of more or less narrow passages, which act as as many throttling points and in the steam flow cause a pressure drop, through which the sound-absorbing effect is achieved.

In the drawing is an embodiment of the muffler according to the innovation shown in longitudinal section in a semaphatic representation.

An expansion pot 1, the steam inlet opening of which 2 pointing downwards is enclosed by a king room 5, its Inner surface of the jacket 4 of the expansion pot 1 is formed. This jacket 4 and the jacket surface 5 of the hanging space 3 are also perforated like a sieve. Between the two lateral surfaces 4 and "5 is cleaned more evenly assorted, granular gravel 6 embedded, which the poräse Forms a throttle layer which completely fills the annular space 3.

As a result of the widening of the cross-section φ & τ , the pressure of the steam entering through the opening 2 is reduced, which is also deflected at right angles to the direction of flow towards the openings in the jacket 4 of the tensioning tip I and in this, as a result of the vortex formation that occurs, experiences a further pressure reduction, so that it is already enters the gravel filling 6 in a significantly relaxed state. In the gravel filling 6, the pressure is further reduced as a result of the friction on the rough and angular surfaces of the individual grains and the narrow passages formed by the latter.

The size of the effective lateral surfaces 4 and 5 and the The thickness of the gravel layer 6 with its cavities must be adapted to the respective conditions (amount and condition of steam).

be fits so that the steam to be relaxed on external pressure through the holes in the jacket surface 5 of the annular space 3 with so low speed escapes, so that no undesired noise can arise.

At the pressures and temperatures of the steam to be discharged (approx. 10-15 aiii and approx. 250-30O ⁰ C), the steam remains overheated even after the throttling, so that it practically does not condense in the gravel layer during operation.
