Titanium automobile exhaust pipe

Abstract

The invention discloses a titanium automobile exhaust pipe. The inner wall of a conical pipe body is provided with a spiral gas groove, and one end, with a large caliber, of the conical pipe body is provided with an intake pipe which communicates with the gas groove, and the gas groove is internally provided with a plurality of purification bulges evenly; the conical pipe body is internally provided with purification elbow pipes made of titanium materials axially, and the purification elbow pipes are hollow pipes with porous structures, and are filled with activated carbon; a second cover bodyis provided with a connecting pipe which communicates with the upper end of the side wall of a cooling chamber, and the lower end of the side wall of the cooling chamber is provided with an exhaust pipe; the cooling chamber is internally provided with a filter screen transversely, and a plurality of flow baffles are arranged above the inner side wall of the cooling chamber and the filter screen evenly; and the outer wall of the cooling chamber is provided with elastic heat-absorbing layers in a sleeving manner. According to the titanium automobile exhaust pipe disclosed by the invention, automobile exhaust comes into full contact with the purification bulges and the purification elbow pipes separately, and the purification effect is good; the exhaust pipe is not liable to vibration, and the service lives of the exhaust pipe and fixing parts thereof are prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobile tail gas emission treatment and relates to a titanium automobile exhaust pipe. Background technique [0002] With the development of society, automobiles are becoming more and more popular, but the exhaust gas emitted by automobiles not only smells weird, but also makes people dizzy and nauseated, which affects people's health. In the case of a small number of vehicles, the self-purification ability of the atmosphere can still dissolve the toxic substances in the automobile exhaust; but with the rapid increase in the number of automobiles, the problems caused by automobile exhaust are becoming more and more serious. Scientific analysis shows that automobile exhaust contains hundreds of different compounds, among which pollutants include solid suspended particles, carbon monoxide, hydrocarbons, nitrogen oxides, etc.; the harmful exhaust gas emitted by a car in a year is three times larger than i...

AI Technical Summary

Problems solved by technology

[0003] The air inlet of most existing automobile exhaust pipes is set at the port of the cylinder body, and the exhaust gas mainly passes through the axis of the cylinder body, but the purification catalytic structure is arranged on the cylinder wall, so that the contact area between the exhaust gas and the purification catalytic structure is small and the contact time is short. Short, which seriously affects the purification effect; the traditional automobile exhaust pipe is a hollow, straight structure, and the exhaust gas of the automobile is always in a high-speed flow state, which makes the exhaust pipe easy to vibrate, thereby reducing the service life of the exhaust pipe and its fixed parts
