Exhaust silencing purifier for automobile

Abstract

The invention relates to the technical field of automobile parts, in particular to an exhaust silencing purifier for an automobile, and provides a combined type automobile exhaust silencing purifier capable of immediately reducing automobile noise and purifying exhaust for the automobile. The exhaust silencing purifier is simple in structure, convenient to use, practical, low in cost and capable of improving practicability. The exhaust silencing purifier comprises an exhaust pipe, a muffling pipe, a first bent pipe, a spiral muffling pipe, a second expansion pipe, a second bent pipe, an air outlet pipe, an automobile chassis and a mounting plate. Filter cotton is arranged in the middle of the left end of the exhaust pipe, a heat recovery device is mounted on the exhaust pipe, the right endof the muffling pipe is matched and connected with the left end of the filter cotton, a first expansion pipe is disposed on the muffling pipe, the right end of the second expansion pipe is connectedwith the top end of the second bent pipe, the left end of the second bent pipe is connected with the right end of the air outlet pipe, two first grooves are formed in the bottom end of the automobilechassis, a silencing and purifying device is placed on the mounting plate, and the top end of the mounting plate is matched and connected with the bottom end of the automobile chassis.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an exhaust muffler for automobiles. Background technique [0002] The noise of automobile exhaust system is an important part of automobile noise. The exhaust system can be regarded as a system composed of pipes and acoustic components. These components allow sound waves of some frequencies to pass through while blocking sound waves of other frequencies, thereby To achieve the noise reduction effect. In the design of exhaust system, the realization of acoustic performance is one of its important design goals. [0003] With the continuous and rapid development of China's economy and society, as of the end of 2017, the number of motor vehicles in the country has reached 3.1 billion, and the number of cars has reached 2.1 billion. The proportion of automobiles has been increasing year after year, and has become the main body of motor vehicles. China has clearly entered the era...

Problems solved by technology

However, the heat energy produced by the automobile engine is only the handle groove (38). Tube heat utilization is particularly important

[0004] At present, the domestic automobile exhaust system is still mainly in the stage of reducing noise, and it cannot achieve noise reduction, resulting in people being in a "noise pollution" environment, which is extremely harmful to people's physical and mental health; There are few studies on the utilization of waste heat in trachea devices, and most of them only use it to heat water, which has a single function and lacks universality, resulting in low practicability
