In order to achieve the purpose, the utility model is realized by the following technical proposal:

The utility model provides a generating set's blast pipe, is including the tubulose body of vertical setting, and tubulose body both ends are all through the end plate shutoff, have seted up the air inlet on the lateral wall of tubulose body lower extreme, have seted up a plurality of ventholes on the lateral wall of tubulose body upper end, are provided with the decurrent baffle of slope on the tubulose body inner wall that is located the air inlet top, and the baffle is just to the air inlet setting, leaves the clearance that the flue gas passed through between baffle free end and the tubulose body.

The utility model discloses the during operation, generating set's waste gas gets into in the exhaust pipe through the air inlet, and waste gas passes through from the clearance between baffle and the tubulose body inner wall, and the venthole on the lateral wall of tubulose body upper end is discharged, and generating set produces a large amount of noises in the course of the work, and the baffle in the exhaust pipe makes the energy attenuation of sound wave on the sound wave reflection in the noise to tubulose body inner wall through the reciprocal reflection of making a round trip, reaches the purpose of making an uproar.

Compared with the prior art, the utility model has the advantages that: because the setting of this internal baffle of tubulose for the noise that produces in the generating set work can carry out the reflection of making a round trip through baffle and tubulose body inner wall, and the energy of sound wave in the decay noise reaches the purpose of making an uproar of falling, and a plurality of ventholes that set up on the tubulose body lateral wall simultaneously compare in current mode of discharging tail gas, and the efficiency of discharging tail gas is higher, and the device is applicable to in the industrial production, has very strong practicality.

The air inlet is connected with an air inlet pipe which inclines downwards, and the air inlet pipe is arranged right opposite to the baffle. The air inlet pipe is arranged obliquely downwards, so that the baffle plate has more obvious reflection effect on sound waves in noise.

And air blocking pipes are sleeved on the side wall of the upper end of the tubular body at intervals, and the air outlet holes are arranged right opposite to the inner wall of the wind shielding pipe. The air blocking pipe is arranged so that when tail gas is discharged, convection can not be formed between the tail gas and outside air, and outside sundries are prevented from entering the tubular body through the air outlet.

The wind blocking pipe is a long conical pipe, the conical tip of the long conical pipe is arranged downwards, a short conical pipe coaxial with the tubular body is arranged on the outer wall of the tubular body below the wind blocking pipe, the conical tip of the short conical pipe is arranged upwards, and a fan-shaped windward surface is enclosed between the long conical pipe and the short conical pipe. The setting of long conical tube and short conical tube makes this blast pipe discharge tail gas, utilizes external air as power for the tail gas that discharges out through the venthole is discharged by long conical tube top, very big improvement tail gas exhaust's speed.

The tubular body is formed by connecting a plurality of sections of circular tubes. The tubular body is divided into a plurality of sections of round pipes to facilitate the installation and the disassembly of the exhaust pipe, so that maintenance personnel can maintain the exhaust pipe daily and clean the inner wall of the exhaust pipe conveniently.
