silencer housing. In addition, the throttles have low axial stiffness, therefore, they can be additional sources of noise due to intrinsic vibrations arising from turbulent pulsations in the steam stream. There is no drainage of accumulating condensate in the muffler, which can lead to destruction of the muffler structure when the condensate freezes at low outside temperatures.

The technical problem solved by the proposed utility model is to increase the efficiency of noise suppression by increasing the smoothness of steam expansion in the stages of the silencer and using additional measures to reduce sound energy in the silencer body and increase the reliability of its operation.

The problem is solved in that the known silencer containing a multi-stage housing made of a number of coaxial shells fastened by the ends, the first stage of the body is connected to the exhaust pipe, the roof, according to a utility model, is additionally equipped with a silencing chamber, a reflector located at the output of the last stage along the axis silencer and facing the concave side to the exhaust pipe provided with cylindrical shells coaxially mounted on the concave side of the reflector on the outside guiding partitions are located at the reflector, while the silencing chamber is made of cylindrical and two conical shells and covers the last step and the reflector with guiding partitions, the inner surface of the silencing chamber is covered with sound-absorbing material, a spiral-coiled mesh is located in all stages of the silencer, the first stage is equipped with a drainage tube, all steps are lined with sound-absorbing material from the outside.

In addition, the silencer can be equipped with stiffeners, tightening the steps and the silencing chamber.

According to the second embodiment, a well-known silencer of steam emission, comprising a multi-stage housing composed of coaxially arranged shells, the first stage of the housing is connected to the exhaust pipe, the roof, according to a utility model, is equipped with a silencing chamber, a reflector located at the output of the last stage along the axis of the silencer and facing the concave side to the exhaust pipe provided with cylindrical shells coaxially mounted on the concave side of the reflector, on the outside of the reflector are located The dividing partitions, the silencing chamber is made of cylindrical and two conical shells and covers the last stage and the reflector with guide partitions, the inner surface of the silencing chamber is covered with sound-absorbing material, a spiral-coiled mesh is located in all stages of the muffler, the first stage is equipped with a drainage tube, all stages are lined with sound-absorbing material, the silencer also has an additional pipeline, the first stage is divided by a partition into parts according to the number of exhaust pipes rovodov, each part has a drainage tube.

In addition, the silencer is equipped with a mounting frame for purge pipelines.

Figure 1 shows a longitudinal section of the proposed device according to the first embodiment, figure 2 - according to the second embodiment,

The steam exhaust silencer (option 1) contains a multi-stage housing 1 composed of coaxially arranged shells 2, the first stage 3 of the housing 1 is connected to the exhaust pipe 4, the roof 5, the silencing chamber 6, the reflector 7, located at the output of the last stage 8 silencer and facing the concave side to the exhaust pipe 4, provided with cylindrical shells 9, coaxially mounted on

the concave side of the reflector 7, on the outside of the reflector 7 there are guides, partitions 10, the silencing chamber 6 is made of cylindrical and two conical shells 11 and covers the last stage 8 and the reflector 7 with the guiding partitions 10, the inner surface of the silencing chamber 6 is covered with sound-absorbing material 12, in all stages 3, 13, 8 of the muffler there is a spiral-coiled mesh 14, the first stage is equipped with a drainage tube 15, all stages 3, 13, 8 are lined with sound-absorbing material 16 from the outside.

In the second embodiment of the device, an additional pipe 17 is provided, the first stage 3 is divided by a partition 18 into parts according to the number of exhaust pipes 4, 17, each part has a drain pipe 15, 19. The device is equipped with a mounting frame for the purge pipes 20.

The operation of the device is to dampen the noise of the stream stream, by successively reducing the stream rate in the silencer by increasing the flow section of each subsequent stage 3, 13, 8 and smoothly expanding the stream of each stage in a spiral-coiled grid 14, which has sufficient axial rigidity. To further reduce noise, a reflector 7 is used, which reflects sound energy towards the exhaust pipe 4, and a silencing chamber 6 is used, in which sound energy is absorbed by sound-absorbing material 12. The noise reduction from the silencer body is also achieved by lining sound-absorbing material 16 of all stages 3, 13, 8 silencers. The presence of the guide walls 10 reduces the aerodynamic drag of the silencer.

Thus, the proposed device can improve the efficiency of damping the noise of the steam discharge in comparison with the prototype.
