Energy-saving automobile exhaust pipe

Abstract

The invention discloses an energy-saving automobile exhaust pipe. The energy-saving automobile exhaust pipe comprises an exhaust pipe body, an exhaust pipe gas inlet pipe, an exhaust pipe gas outlet pipe, an exhaust pipe four-level filtering element cylinder and a connection flange. The exhaust pipe gas outlet pipe is designed and manufactured into an isometric cylindrical structure. The exhaust pipe gas inlet pipe is designed and manufactured into a reversed horn-shaped taper structure and is connected with an automobile tail pipe through the connection flange. The exhaust pipe four-level filtering element cylinder is arranged at the front end of the exhaust pipe gas outlet pipe, is convenient to replace frequently and is composed of four levels of filtering structures including activated carbon, asbestos, a molecular sieve filtering element and a fiber filtering membrane. The exhaust gas pipe body and the connection flange are both made of heat-resisting stainless steel materials, and the inner surface and the outer surface of the exhaust gas pipe body and the inner surface and the outer surface of the connection flange are subjected to dacromet and zincizing combined anti-corrosion treatment. The energy-saving automobile exhaust pipe is scientific in design, simple in structure, convenient to mount and demount, capable of absorbing and purifying automobile tail gas and protecting the environment and also capable of effectively preventing corrosion of harmful gas to the exhaust pipe body under the high-temperature environment, the service life of the exhaust pipe is prolonged, and the production cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of automobile key parts manufacturing, in particular to an energy-saving automobile exhaust pipe. Background technique [0002] With the popularity of family passenger cars, especially the full-load work of urban taxis, air pollution caused by car exhaust emissions has become the chief culprit in the deterioration of PM2.5 environmental indicators. At present, most small car exhaust pipes are of single-tube structure, and the exhaust gas is directly discharged without treatment, which seriously affects air quality and pollutes the urban environment. In addition, the working environment of the automobile exhaust pipe itself is harsh, and it is exposed to high temperature and harmful gas environment for a long time. The exhaust pipe itself corrodes seriously and has a low service life. Summary of the invention [0003] In order to solve the above problems, the present invention provides an energy-saving automobile ...
