Waste heat power generation silencing system

The utility model discloses a waste heat power generation silencing system which structurally comprises an outer shell, an inner shell, a cavity, a steam silencer, circulating water, a steam inlet pipe, a circulating water inlet pipe, a circulating water outlet pipe, a sealing cover and a silencing exhaust pipe. By means of the property that the density and the specific volume of water are larger than those of air, pressure reduction and cooling of high-pressure steam (the size is reduced after the steam is cooled and condensed) are facilitated, so that the silencing effect of the steam silencer is enhanced, and noise generated by discharging of the high-pressure steam is reduced; and the content of air in the containing cavity is detected through the vacuum sensor, so that the containing cavity is kept vacuum, outward transmission of noise is reduced, and the silencing effect is improved. 本实用新型公开了一种余热发电消音系统，其结构包括外壳体、里壳体、空腔、蒸汽消音器、循环水、蒸汽进管、循环水进管、循环水出管、封盖和消音排气管，本实用新型具有以下有益效果，蒸汽消音器将噪音引入水中，利用水的密度和比容大于空气的性质，利于高压水蒸
