Point has practicability outstanding.
To achieve the above object, the technical solution of the utility model is：
A kind of bypassing exhaust device, is set to the outlet side of exhaust gas treating device tailpipe, bypassing exhaust device mainly by
Shell and the flow-disturbing grid composition being set in shell, shell are equipped with air inlet and gas outlet, and air inlet passes through ingress pipe
It is connected with the outlet side of exhaust gas treating device tailpipe, flow-disturbing grid is also equipped at gas outlet.
Preferably, the roof of shell is fixed on by fixing bracket lifting on vehicle frame.
Preferably, fixing bracket by corner bevelling pipe and is individually fixed in the upper connector of corner bevelling pipe upper and lower side and lower connector
Composition, the lower end of corner bevelling pipe are fixed on the roof of shell by lower connector, and the upper end of corner bevelling pipe is fixed on by upper connector
The outside of longitudinal beam.
Preferably, air inlet is located at the front of case inside, and gas outlet is located at the rear side of shell and is tilted towards obliquely downward.
Compared with prior art, the utility model has the beneficial effects that：
1. bypassing exhaust device provided by the utility model is set to the outlet side of exhaust gas treating device EGP exhaust pipes, can
The temperature of exhaust gas, is effectively ensured neighbouring pedestrian and the nearby safety of each component, has practicability outstanding after effective reduction processing.
2. the main part of the utility model（Shell）It is fixed on longitudinal beam by the fixing bracket being especially arranged, it should
Fixing bracket can be by the main part of exhaust flow splitter（Shell）It is set to frame outside, it is not only convenient for disassembly and assembly, while being also vehicle
Enough spaces are reserved immediately below, do not influence arrangement.
3. the utility model is by the method for gas distribution flow-disturbing come to treated, exhaust gas cools down, this method is energy saving
Environmental protection also effectively reduces energy consumption while ensureing cooling-down effect.
