First silencing apparatus that the present embodiment is provided, is the silencing apparatus for Diesel engine, and main purpose is
Absorb the noise produced when being worked by engine.The silencing apparatus is arranged on the inside of Jing Yin casing, the row with Diesel engine
Tracheae is connected, and the waste gas noise of engine discharge carries out noise reduction process by the silencing apparatus.The silencing apparatus can be referred to as
Air exhaust muffler device, concrete structure can use a variety of noise elimination structures of the prior art, such as resistance type, anti-type, impedance complex
Type etc. just has the noise elimination structure of certain volume shape；It is preferred that the noise elimination structure of impedance composite, the structure has noise elimination frequency domain wide
The characteristics of.Further, in order to promote the radiating that diesel-driven generator is overall, it is to avoid the waste-gas heat of engine discharge has influence on quiet
Radiating in sound box bodies, it is preferred that air exhaust muffler device is isolated with silencing case body heat, air exhaust muffler device is independently arranged at
One jiao of top in silencing case body.Further, in order to preferably reduce noise during tail gas discharge, preferably in exhausting silencer
One layer of noise reduction backplate of outside cladding of device, can either play the effect being thermally isolated, can also play the effect of noise reduction.
Second silencing apparatus that the present embodiment is provided, is the silencing apparatus for being directed to the Jing Yin casing with axial flow blower,
Main purpose is to absorb the noise produced when being worked by axial flow blower.The silencing apparatus is arranged on the inside of Jing Yin casing, with axle
The shell of flow fan is directly connected to or is provided on the closed type air passage between axial flow blower and engine.This disappears
Acoustic device can abbreviation fans silencer, concrete structure can use a variety of noise elimination structures of the prior art, for example, resistance type,
Anti- type, impedance composite etc., still, these structures need to occupy certain space, influence whether the overall body of diesel-driven generator
Product, therefore be not very good.It is preferred that, fans silencer is set to strip-type silencer, with small volume, easy to process etc.
The characteristics of.Further, strip-type silencer is preferably the perforated plate composition using cladding sound-absorbing material, and this perforated plate, which has, to disappear
The characteristics of audio frequency field width.Jing Yin casing with axial flow blower, can also set the air duct and kuppe of closing, kuppe
The body fan of Diesel engine can be coated, kuppe is connected by being flexible coupling with the axial flow blower of air inlet louvers, a side
Face can avoid cold air from being muted the heat in casing, the effect that on the other hand also there is extension to eliminate the noise.
The 3rd silencing apparatus that the present embodiment is provided, is for the overall silencing apparatus of diesel generation group, main purpose
It is to set to handle for diesel-driven generator all component sound-absorbing, sound insulation in the inside of Jing Yin casing.The silencing apparatus is specifically quiet
