Automobile exhaust purification type exhaust cylinder

Abstract

The invention discloses an automobile exhaust purification type exhaust cylinder, which includes a shell. The shell is externally provided with evenly distributed cooling fins, an upper cover sleevesthe upper end of the shell, a lower cover sleeves the lower end of the shell, and the upper cover is provided with a through hole; one end of a guiding pipe communicates with the exhaust cylinder of an automobile, the other end of the guiding pipe penetrates through the through hole of the upper cover and is fixedly connected with a filter nozzle, the inner wall of the filter nozzle is fixedly connected with a flow guiding block, the filter nozzle is externally provided with an air inlet pipe, and the air inlet pipe is fixedly connected with the upper cover; and the air inlet pipe is fixedly connected with a spiral pipe with a porous structure on the surface through a layered partition plate, the spiral pipe is internally filled with activated carbon, the spiral pipe is externally wrappedwith a layer of filter net, the bottom of the spiral pipe is transitively connected with an air outlet pipe, and a sealing pad is installed at the joint. According to the automobile exhaust purification type exhaust cylinder, through the filter nozzle, the activated carbon and a catalytic layer, the action of attachment, filtration, catalysis is achieved, and thus the problems of incomplete automobile exhaust purification and high cost are solved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an automobile tail gas purification type exhaust pipe. Background technique [0002] At present, with the development of science and technology, people's living standards are gradually improving, and automobiles have become an essential travel tool for every family. However, with the increase in the use of automobiles, the exhaust gas emitted by automobiles is also increasing day by day. Because the exhaust gas emitted by automobiles contains nitrogen, Carbon monoxide, carbon dioxide, unburned hydrocarbons, carbon nitrogen compounds, nitrogen oxides, sulfur dioxide and other gases harmful to the environment and human body, leading to air pollution, and global warming lead to various natural disasters, such as El Niño phenomenon and La Niña Phenomena and so on have brought severe challenges to the survival of human beings, so the treatment of automobile ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a kind of automobile tail gas purifying type exhaust pipe, to solve the problem raised in the above-mentioned background technology, it has the beneficial effect that; through the filter for the first time filtering and adhesion, the exhaust gas in the car tail gas is preliminarily reduced. Solid particles, the pre-filtered exhaust gas enters the spiral tube through the through hole on the partition plate, and the activated carbon in the spiral tube absorbs and filters harmful substances in the exhaust gas again, and the spiral tube is hollowed out, so that the exhaust gas filtered and adsorbed by activated carbon It can be further purified through the catalytic layer on the inner wall of the shell, and then the exhaust gas after attachment, filtration and catalysis is discharged through the outlet pipe, thus solving the problems of incomplete purification and high cost
