As preferably, described casing is made by steelframe and the sound-absorbing composite board that is fixed on the steelframe, the thickness of this sound-absorbing composite board is 100～180mm, and this sound-absorbing composite board is made up of sound-absorbing material in the filling interlayer of metal shell plate and metal shell plate and chatter plate.
As preferably, the forward and backward both sides of described casing also are respectively equipped with the active door of two fans, casing can open and cut out.
As preferably, the sidewall of noise elimination air inlet duct and noise elimination air exhaust channel is made up of sound-absorbing material in the filling interlayer of metal perforated plate, metal perforated plate and chatter plate.
As preferably, described exhaust silencer is the silencing type exhaust silencer.
As preferably, be between described casing, diesel generating set and the exhaust silencer and removably connect.
As preferably, described exhaust silencer is arranged on box house, and its relief opening is communicated with the noise elimination air exhaust channel.
As preferably, described exhaust silencer is arranged on the casing top.
Compared with prior art, advantage of the present utility model is: guaranteeing to have realized the encapsulation noise elimination under the ventilation and heat prerequisite effectively, noise does not have direct projection, noise reduction is big, noise elimination ventilation flue low-resistance, circulation is good, simultaneously, adopt the silencing type exhaust silencer, realized quiet synchronously with sound proof box, casing and diesel generating set are combined into one, available lifting, automobile transportation, also configurablely on vehicle frame, haul conveniently moving; In addition, the casing acoustic board is in absorption and the sound insulation of selecting low, the mid-frequency noise that overweights large and medium-sized diesel generator aspect thickness and the sound-absorbing material filling unit weight, and is with strong points.
