Automobile exhaust filtering device

Abstract

The invention discloses an automobile exhaust filtering device which comprises a shell. An air inlet pipe is installed at the left end of the shell. An end cover is arranged at the right end of the shell. A connecting pipe is integrally formed on the left side face of the end cover. A thread is formed on the surface of the connecting pipe. The connecting pipe is connected with the right end of the inner surface of the shell through the thread. First convex lugs are evenly distributed at the right end of the outer surface of the shell. Second convex lugs matched with the first convex lugs are arranged on the end cover. The first convex lugs and the second convex lugs are connected through bolts. An exhaust pipe is installed in the middle of the right side face of the end cover. According to the automobile exhaust filtering device, first diffluence holes in a first partition plate and second diffluence holes in a second partition plate are matched so that gas entering the shell can be subjected to diffluence, and the flowing stroke of exhaust gas inside the shell is increased; due to the fact that the first diffluence holes are formed around the first partition plate at equal intervals, exhaust diffluence is uniform, and the filtering effect is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an automobile exhaust filter device. Background technique [0002] With the continuous progress of life, automobiles have widely become the means of transportation for people to go out. Therefore, the emission of automobile exhaust needs to be strictly controlled. The automobile exhaust filter device is a device installed on the exhaust pipe of the automobile to purify the automobile exhaust. There is activated carbon in the casing, and the automobile exhaust is filtered and purified by the activated carbon before being discharged to the outside, thereby reducing the emission of harmful gases. The structure of the current exhaust gas filter is mostly complicated, and the activated carbon inside is difficult to replace, which leads to the reduction of the filtering effect of this exhaust filter after a period of use. If it is replaced as a whole, the cos...

Problems solved by technology

The structure of the current exhaust gas filter is mostly complicated, and the activated carbon inside is difficult to replace, which leads to the reduction of the filtering effect of this exhaust filter after a period of use. If it is replaced as a whole, the cost will be high, and this exhaust filter Due to the uneven distribution of the exhaust gas and the unreasonable flow diversion of the device, the flow stroke of the exhaust gas in the shell is too short, and the filtering effect is not ideal.
