Heat energy recovery type boiler exhaust silencer

Abstract

The utility model discloses a heat energy recovery type boiler exhaust silencer, which relates to the technical field of boiler exhaust silencing, and comprises a silencing pipeline I. A silencing pipeline II is fixedly connected above the silencing pipeline I. When a boiler exhausts, exhaust gas exhausted by the boiler rushes into a buffer tank from an air inlet pipeline, enters the buffer tank, and then enters the buffer tank. As the space in the tank is suddenly increased, the waste gas is forced to diffuse, and the flow velocity is rapidly reduced, the aerodynamic noise generated when the waste gas flows is reduced, and the air flow has enough time to redistribute and balance the pressure in the buffer tank, so that the pressure of the air flow discharged from the buffer tank is more stable, the noise generated by pressure pulsation is reduced, and the service life of the buffer tank is prolonged. Then waste gas in the buffer tank flows to the silencing pipeline I and the silencing pipeline II and is finally discharged from the cover plate, and noise generated by the waste gas is absorbed by the rock wool I and the rock wool II when the waste gas passes through the silencing pipeline I and the silencing pipeline II, so that the problem that high-decibel noise affects the health of workers is solved.
