    The invention relates to mechanical engineering, 3 specifically to the noise mains of boiler installations, in the private network of exhaust steam from industrial power boilers. Known silencer containing a cylindrical body, provided with an inlet grille, a tubular element made of a variety of pipes, and inlet and outlet nozzles ti 1. However, the known device is not suitable for jamming high frequency noise and, therefore, has a low jamming efficiency. The purpose of the invention is to increase the efficiency of sound attenuation. This goal is achieved by the fact that in the boiler muffler of noise, in particular the outlet pair, which has a cylindrical body, equipped with an inlet grill, a tubular element made of a plurality of pipes, and inlet and outlet pipes, the casing is additionally equipped with a perforated nozzle placed between the inlet pipe and the tubular element and covered with sound-absorbing material, the inlet grille is made with a gap of 5-10 mm, and the exhaust pipe is made in the form of a perforated diffuser equipped with an exhaust grille with a lumen of 5-30 mm and covered with sound-absorbing material, the inlet grille being installed at a distance of 50-500 mm from the inlet pipe, the opening angle of the diffuser of the discharge pipe is: the diameter of the inlet pipe 3-5, the ratio of the length of the diffuser of the outlet pipe to the diameter of the body is at least 1, and the ratio of the length of the perforated nozzle to the diameter of the inlet pipe is not less than 12. Moreover, the body in the area of the tubular element can be made in the form of a heat exchanger with inlet and outlet fittings, and baffles are installed between the pipes. FIG. 1 shows a silencer, longitudinal section; in fig. 2 shows a method for connecting a battery silencer; in fig. 3 - method of connecting a single muffler; in fig. 4-boiler noise muffler with a heat exchanger. The boiler silencer (Fig. 1) consists of a cap with an inlet pipe 1, which is attached at a distance of 50 to 500 mm with brackets, an inlet grille 2 consisting of three nozzles coaxially arranged in the inlet part of the perforated expansive nozzle 3, forming together with a cylindrical body 4 a chamber with a variable cross-section, filled with sound-absorbing material 5. The outlet part of the perforated nozzle 3, in which the pressure gauge 6 is mounted, is connected to a tubular element 7 made of a plurality of pipes to which it is attached Flax outlet pipe, perforated in the form of a perforated diffuser 8 with an opening angle of 0-15 and with sound-absorbing material 9 with a superposed cone 10, to the bases of which through the flange of the diffuser 8 an output grille 11 is attached. The boiler muffler (figure 4) can be made with a heat exchanger containing an inlet 12 and an outlet 13 nozzle, and baffles 14 are installed between the pipelines. The lattice gap is the size of the square mesh of the lattice, so that for the clearance of the inlet grate 510 mm this size is 5x5 8x8 - 10; c10, and for the lumen of the output grating 5-30 mm, this size is 5x5 -20x20 - 30x30 mm. The ratio of the diameter of the housing 4 to the diameter of the inlet 1 is 3-5, the ratio of the length of the diffuser 8 to the diameter of the housing 4 is not lower than 1, and the ratio of the length of the nozzle 3 to the diameter of the inlet 1 is not less than 12. The silencer works as follows. The high-pressure steam supplied from the outlet pipe through the inlet pipe 1 flows successively through three successively installed nasas; The entrance grille 2. A variable cross-section chamber formed between the perforated expansive nozzle 3 and the body 4 is filled with sound-absorbing material 5. The steam expanded in the nozzle 3 flows through a tubular element 7 consisting of a plurality of tubes in which it is divided into jets, which causes Significant dissipation and damping of acoustic energy. 8 individual streams flowing into a common perforated diffuser, the sound waves and the accompanying sound waves are subjected31 with further ry to an intense damping Posagnke directly on the diffuser's flange 8. The output grille 11 additionally dampens sound waves. The water supplied (Fig. 4) through the nozzle 12 flows successively between the partitions 14, takes a significant amount of heat contained in the steam, and is not heated to a temperature of 100 ° C, and then is discharged through the nozzle 13 to the outside. The use of 9 both direct and countercurrent methods of steam cooling with water additionally reduces the noise level by 7-10 dB. In addition, warmed water, depending on the conditions and needs of the STATE, can be used for social or technological purposes. Thus, the device makes it possible to increase the efficiency of sound attenuation.
