Description

The excellent emission type muffler of high sealing

Technical field

The utility model relates to muffler technical field, specially a kind of excellent emission type muffler of high sealing.

Background technique

Muffler is a kind of device for preventing sound transmission and air-flow being allowed to pass through, and is the weight for eliminating air power noise Want measure.Muffler is mounted in air powered equipment, such as air blower, air compressor machine, boiler exhaust mouth, generator, water pump row The device of reduction noise on the airflow channel of the biggish equipment of port noise or in inlet and exhaust system, the type of muffler is very It is more, but study carefully its noise elimination mechanism, and they can be divided into six kinds of main types, i.e. resistive muffler, resistant noise-reducing device, impedance Complex deafener, microperforated panel muffler, aperture muffler and active muffler.

Currently, muffler mainly reduces noise using sound-absorbing porous material, sound-absorbing material is fixed on air-flow and is led to It is arranged in the duct on the inner wall in road or according to certain way, just constitutes resistive muffler, when sound wave enters resistive muffler When, a part of sound can rub in the hole of porous material and be converted to thermal energy consumption and dissipate, makes to weaken by the sound wave of muffler, But existing muffler is during use, since leakproofness is inadequate, to will lead to gas and waste oil is easy to produce and lets out Dew.

Utility model content
