And the inwall connection of shell is mounted with interior warehouse, the inside of the interior warehouse disappears through being mounted with the first noise elimination filter disk and second
Absorption wallboard is provided between sound filtering table, and the first noise elimination filter disk and the second noise elimination filter disk, between the absorption wallboard
Region be gas channel, the inside of the interior warehouse is through being connected with upper outlet and lower outlet, the first noise elimination filter disk
Including filtering table outer ring, filtering table inner panel and airflow hole, the second noise elimination filter disk includes filtering table outer ring, filtering table inner panel
With absorption baffle plate.
Preferably, the shell generally cylindrical structural.
Preferably, Sound-proof material is filled between the shell and interior warehouse.
Preferably, the first noise elimination filter disk is disc-shaped structure, and airflow hole is provided with three altogether.
Preferably, the absorption baffle plate is mounted with nine around filtering table outer ring, and its length scale is different.
Compared with prior art, the beneficial effects of the utility model are：The duct type muffler, using duct type knot
Structure is designed, by the positioned inside of pipeline have multi-filtering dish structure carry out air-flow lower noise process, Ran Houyi
The secondary process entirely eliminated the noise by outlet, realization from air flow inlet end.
