The invention discloses an automobile exhaust purification silencer capable of increasing contact between silencing cotton and air. The automobile exhaust purification silencer comprises an exhaust pipe, a second baffle plate is fixedly mounted at one end of the exhaust pipe, a mounting hinge plate is hinged to the outer side of the second baffle plate, the inner side of the mounting hinge plate fixedly sleeves an air outlet pipe, an outlet filter block is fixedly mounted on the inner side of the air outlet pipe, a branch pipe is fixedly mounted on the inner side of the second baffle, and an exhaust hole is formed in the branch pipe. By means of a honeycomb disturbance pipe and a silencing disturbance block, the honeycomb disturbance pipe gathers airflow to be spirally exhausted when a first spiral purification pipe and a second spiral purification pipe correspondingly perform purification, the detonation kinetic energy of tail gas is preliminarily reduced, sound waves are relieved, the airflow is scattered through honeycomb small holes of the honeycomb disturbance pipe, the airflow kinetic energy is further eliminated, the silencing effect is enhanced, the silencing disturbance block further disperses the tail gas flow entering the tail gas pipe and reduces the vibration of the airflow, so that the airflow is silenced at the initial stage, and the subsequent silencing is perfected.

    本发明公开了一种增大消音棉与空气接触的汽车尾气净化消声器,包括尾气管,尾气管的一端固定安装有第二挡板,第二挡板的外侧铰接有安装铰接板,安装铰接板的内侧固定套接有出气管,出气管的内侧固定安装有出口滤块,第二挡板的内侧固定安装有支管,支管的内部开设有排气孔。通过蜂窝扰动管和消音扰动块,蜂窝扰动管在第一螺旋净化管和第二螺旋净化管分别净化时将气流聚向螺旋排出,将尾气爆燃动能初步消减减轻了音浪,并且经由蜂窝扰动管的蜂窝小孔打散气流,将气流动能进一步消除,增强了消音效果,消音扰动块将进入尾气管内的尾气流,进一步分散,并且将气流的震动消减,使得气流在初步阶段就被消音,完善了后续的消音。
