A Diesel Engine Muffler with Soot Particle Collection Function

Abstract

The invention provides a diesel engine muffler with a charcoal smoke particulate collecting function. The diesel engine muffler is characterized in that a baffle capable of being pushed by waste gas is arranged in a front muffler tube of the diesel engine muffler; a moving rod vertical to the end surface is arranged on the end surface, back on to a gas inlet of the front muffler tube, of the baffle; a baffle reset elastic piece is arranged on the moving rod in a sleeving manner; the initial end of the moving rod is connected with the baffle; the baffle compresses the baffle reset elastic piece when being pushed by the waste gas; an inner brush in contact with the inner wall of the front muffler tube is arranged on the periphery of the baffle; the tail end of the moving rod is connected with a brush frame, and an outer brush in contact with the outer wall of a rear muffler tube is fixed at the end part of the brush frame; when being pushed by the waste gas entering from the gas inlet of the front muffler tube, the baffle drives the inner brush to clean the inner wall of the front muffler tube; the baffle pushes the moving rod, so that the outer brush cleans the outer wall of the rear muffler tube; when gas stops entering the gas inlet, the baffle reset elastic piece pushes the baffle to move and reset towards the gas inlet of the front muffler tube so as to drive the inner brush and the outer brush to clean again; mechanical cleaning and dust removing equipment can be integrated on the muffler to clean tail gas from a diesel engine.

Description

technical field [0001] The invention relates to the field of diesel engines, in particular to a diesel engine muffler with the function of collecting soot particles. Background technique [0002] The function of the existing muffler is single, it can only reduce the noise generated during the exhaust process, and it is helpless to capture or eliminate the soot particles. The purification technology of diesel engine soot particles is mostly filtered by wall-flow particulate filter (DPF). As the filtered particles gradually accumulate, DPF will be blocked, which will increase the exhaust back pressure of the engine, improving power and economy. The decline, therefore, must remove the soot particles accumulated in the DPF in a timely manner, a process called regeneration. Although the DPF has a good trapping effect on soot particles, the regeneration of this device is very difficult, and methods such as electric heating or fuel injection are required to burn the soot particles...

AI Technical Summary

Problems solved by technology

Although the DPF has a good trapping effect on soot particles, it is very difficult to regenerate this device, and it needs electric heating or fuel injection to burn the soot particles

Therefore, not only the material tolerance and service life of the DPF are difficult to meet the requirements, but also the structure of the entire post-processing device is complicated and the cost is expensive.

[0003] Due to the defect of DPF, many diesel vehicles in use do not have after-treatment devices for exhaust gas. The exhaust gas is directly discharged into the atmosphere after passing through the muffler. Therefore, the interior of the muffler is covered with soot particles. It rushes out of the exhaust pipe together with the airflow, causing serious air pollution

Only when the muffler is disassembled and cleaned regularly can the phenomenon of black smoke be improved, but this method of disassembling and cleaning the muffler frequently is difficult to be adopted by users
