Motor vehicle filtering silencer

Abstract

The invention relates to a filtering silencer for motor vehicle, comprising a metal casing and a ceramic inner core. The ceramic inner core is positioned inside the cavity of the metal casing. An air inlet and an air outlet are arranged on the ceramic inner core. The air inlet of the inner core, the cavity of the ceramic inner core, and the air outlet of the inner core are communicated with each other. Upper and lower ceramic baffles are arranged inside the cavity of the ceramic inner core. Bee holes are respectively arranged on the upper and the lower ceramic baffles. The upper and the lower ceramic baffles, and the medial wall of the ceramic inner core cavity form a cavity of millipore filtering materials. The air inlet of the inner core is communicated with the air outlet of the inner core through the bee holes and the cavity of the millipore filtering materials. Millipore filtering materials are arranged inside the cavity. The filtering silencer for motor vehicle has the advantages of adsorbing and filtering waste gas emitted by the engine, reducing the emission of noise and waste gas, solving the rusting problems of the metal casing and the inner core, lengthening the service life without need to change due to no corrosion, saving steel, and facilitating rinsing and assembly.

Description

technical field [0001] The present invention relates to a flow muffler or exhaust device of a machine or engine, a flow muffler or exhaust device of an internal combustion engine, and in particular to a motor vehicle filter muffler. Background technique [0002] Present motor vehicle muffler, wherein comprises metal shell, has shell air inlet on the metal shell left side wall, has shell exhaust port on the metal shell right side wall; Harmful gases such as carbon dioxide and sulfur dioxide are corroded, and the shell and inner core are easily rusted; it not only wastes steel materials, but also shortens the service life. At the same time, harmful gases are discharged without filtering and cause environmental pollution. Contents of the invention [0003] The purpose of the present invention is to provide a motor vehicle filter muffler with good use effect. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a filter mu...
