Exhaust pipe with excellent silencing effect for dangerous goods transport vehicle

The invention discloses an exhaust pipe with an excellent silencing effect for a dangerous good transport vehicle. The exhaust pipe comprises an exhaust pipe body and a cooling plate, wherein a heat shield is arranged on the outer side of the exhaust pipe body; the exhaust pipe is in detachable connection with the heat shield; a groove is formed in the heat shield; the cooling plate is embedded into the groove; the cooling plate and the heat shield are in detachable connection; and cooling fins are arranged on the inner side of the cooling plate. The heat shield, as well as the cooling plate and the cooling fins, which are arranged inside the heat shield, can be used for heat heat insulation and cooling, so that the exhaust pipe can not be over-heated, and accordingly, internal elements are protected. Since a ceramic carrier plate, a fine filter screen and a coarse filter screen are arranged on a spark arrester of the exhaust pipe, tail gas in the exhaust pipe can be purified by meansof the ceramic carrier plate, the fine filter screen and the coarse filter screen. Thus, the function of the spark arrester is increased. The exhaust pipe is convenient to use.
