ラントの連続運転が不可能になる。[Detailed description of the invention] When a porous sound absorber used as a sound absorber in a conventional silencer becomes clogged with dust, ash, etc. contained in the gas, the sound deadening performance deteriorates significantly. When a silencer is installed in a see-through draft fan for a boiler or an induced draft fan for a denitrification equipment, dust, ash, and acidic ammonium sulfate (in the case of an induced draft fan for a denitrification equipment) contained in the boiler exhaust gas may be removed from the silencer. It adheres to sound absorbers, clogging them and requiring frequent cleaning, making continuous operation of thermal power plants impossible.

中で使用される消音器に応用されるものである。 The present invention consists of multiple layers of sound absorbers each having an air outlet provided between two layers of porous sound absorbing material, arranged in a gas flow path with their outer surfaces substantially parallel to the gas flow. It is an object of the present invention to provide a silencer for a boiler, which is characterized by forming a structure with low pressure loss and blowing air from the air outlet through the porous sound-absorbing material into the flow path. It is applied to induced draft fans, induced draft soil silencers for denitrification equipment, and other silencers used in gaseous air containing dust.

The diagram will be explained. FIG. 1 is an explanatory diagram of one embodiment of the noise muffling device of the present invention, and FIG. 2 is a detailed diagram of its sound absorbing body. 1 is a duct, 2 is a muffler outer plate, 3 is a sound absorber (porous) having an air intake port between multiple layers of porous sound absorbing material, 4 is an air outlet, 5 is an air flow direction, and 6 is a The airflow surface, 7, indicates a void. The muffling device is composed of a muffler outer plate 2 and a sound absorber 3, and airflow is muffled by passing through a passage with low pressure loss between the sound absorbers 3. Each sound absorber consists of a two-sided sound absorber block, the outer surface of which is placed in the gas flow path substantially parallel to the gas flow, and an air outlet 4 is provided in the gap 7 between the two sides.
