A diesel engine exhaust muffler and particle capture integrated device

Abstract

The invention discloses an integrated device for noise reduction and particle capture of diesel engine exhaust, comprising a barrel-shaped wall, a noise reduction mechanism and a particle capture mechanism; a support plate is arranged at the inner lower end of the barrel-shaped wall, and an air intake pipe is inserted at the upper end. The air inlet chamber is communicated with the first muffler pipe through the air inlet; the left side of the first muffler pipe is provided with a second muffler pipe; muffler mechanism; the lower fixing plate is integrated with the upper wall of the air inlet chamber; a plastic burning plate is arranged between the lower fixing plate and the supporting plate; the upper end of the lower fixing plate is sequentially provided with an upper fixing plate and a blowing ring; the blowing ring , The plastic burning plate, the upper fixing plate and the lower fixing plate constitute the particle capturing mechanism. The invention has the advantages of high integration, compact structure, small footprint and low production cost; the secondary noise reduction and multi-layer filtering treatment can effectively improve the noise reduction effect and particle capture rate of diesel engine exhaust.

Description

technical field [0001] The invention relates to an integrated device, in particular to an integrated device for exhaust gas silencing and particle capture of a diesel engine, belonging to the technical field of exhaust gas treatment equipment. Background technique [0002] Diesel engines are widely used in construction machinery, ships, heavy-duty vehicles and other fields because of their low fuel consumption and high torque output, and also have a high proportion of popularization and application in the field of foreign cars. With the increasingly prominent environmental problems, the emission standards formulated by various countries are gradually increasing, especially for the exhaust noise and particle emissions of diesel engines, which put forward more stringent requirements. Although diesel engines are currently equipped with many treatment devices for exhaust noise and particle emissions, they are all independent function mufflers and particle traps, which are not on...

Problems solved by technology

Although the current diesel engine has been equipped with many treatment devices for exhaust noise and particle emissions, they are all independent function mufflers and particle traps, which are not only complicated to install, but also occupy a large space, and the performance needs to be further improved
