Abstract

The invention discloses a silencer for a nuclear power unit. The silencer comprises a silencing tube body, a connecting pipe and an exhaust opening, as well as a multi-stage silencing body and a sound absorber which are arranged in the silencing tube body, wherein the connecting pipe is arranged in the silencing tube body and extends out of the bottom of the silencing tube body; the multi-stage silencing body is arranged at the periphery of the connecting pipe and comprises a plurality of silencing plates arranged side by side, as well as an upper fixing plate and a lower fixing plate which are arranged at the tops and the bottoms of the silencing plates; the exhaust opening is formed in one side of the top of the silencing tube body, and the sound absorber is arranged in the exhaust opening; and an end socket is arranged at the top of the connecting pipe. According to the silencer for the nuclear power unit, noise generated in the exhaust process is greatly reduced, so that the noise reduction effect is good, the noise reduction standard of a nuclear power system can be met, and noise pollution is reduced.

Description

technical field [0001] The invention relates to a muffler, in particular to a muffler for a nuclear power unit. Background technique [0002] The muffler is a device that prevents sound transmission and allows airflow to pass through, and is an important measure to eliminate aerodynamic noise. The muffler is installed on the air flow channel of aerodynamic equipment (such as blower, air compressor, boiler exhaust, generator, water pump and other equipment with high exhaust noise) or in the intake and exhaust system to reduce noise. device. [0003] With the development of my country's nuclear power industry, nuclear power accompanies our lives and reduces human dependence on coal and other non-renewable energy sources. In the process of nuclear power application, due to its complex system, and the protection level and execution standards are higher than general standards, and Due to the large load during the operation of nuclear power plants, the exhaust noise is much highe...
