Internal combustion engine exhaust device

Abstract

The invention discloses an internal combustion engine exhaust device. The internal combustion engine exhaust device comprises an exhaust device body; the exhaust device body includes an intake pipe; an expansion chamber is arranged on one side of the intake pipe; a filter device is arranged on one side, far from the intake pipe, of the expansion chamber; a first filter layer and a second filter layer are arranged in the filter device far from the intake pipe in sequence; one side, far from the expansion chamber, of the filter device is fixedly connected with a ternary catalyst through a ventilation pipe; a netty separation plate is arranged in the ternary catalyst, and is provided with a purifying agent; and the purifying agent includes a carrier and a catalyst. Particles included in exhausted gas can be effectively filtered to reduce the atmospheric pollution from the exhausted gas of an internal combustion engine, so that the exhausted gas can achieve the emission standard, the requirement of a traditional exhaust device on purification is satisfied, the noise generated by a main body of the exhaust device is the lowest, the noise pollution on roads is reduced, and the overall silencing effect of the main body of the exhaust device is improved.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to an exhaust device for internal combustion engines. Background technique [0002] Gasoline engines, diesel engines, gas turbines and other internal combustion engines often contain carbon monoxide, nitrogen oxides, hydrocarbons, lead, and solid suspended particles. Because these exhaust gases pollute the air and endanger health, it is often necessary to discharge the exhaust gas into the atmosphere. The exhaust gas is purified, and water, as a cleaning agent and acid gas solvent, can well filter solid suspended particles, lead particles, and acid gases in nitrogen oxides and hydrocarbons in the exhaust gas. There are also related The exhaust gas purification device is generally equipped with a rotating shaft driven by a motor in a cylindrical exhaust gas purification box, and a plurality of discs are arranged on the rotating shaft. Clean water is injected into ...

AI Technical Summary

Problems solved by technology

However, when this exhaust gas purification device is actually used, it is found that the exhaust gas purification device of this structure has a low purification efficiency for exhaust gas, and the exhaust gas discharged after purification cannot meet the emission standard and cannot meet the purification requirements. The effect is average, the structure is complicated, and the manufacturing cost is high. Now a new technical solution is needed to solve the above problems
