Three-way catalytic exhaust pipe with guide plates

导流板三元催化排气管

Abstract

本发明申请公开了一种导流板三元催化排气管。方案为:包括排气管本体,排气管本体的一端为进气孔,另一端为排气孔,排气管本体内靠近进气孔设有过滤层,排气管本体内过滤层至排气孔之间设有导流板,导流板面积大于排气管本体横截面积的一半,导流板在排气管本体内径向交错设置,导流板之间设置有水平的三元催化层。本发明申请意在提供一种导流板三元催化排气管,以解决现有技术中由于过滤板设置在管道内壁上,无法使得全部尾气都经过过滤板,使得过滤效果有限的问题。
The invention discloses a three-way catalytic exhaust pipe with guide plates. According to the scheme, the three-way catalytic exhaust pipe comprises an exhaust pipe body, one end of the exhaust pipe body is provided with a gas inlet, and the other end of the exhaust pipe body is provided with an exhaust hole, and the portion, close to the gas inlet, in the exhaust pipe body is provided with a filtering layer; and the guide plates are arranged between the filtering layer and the exhaust hole in the exhaust pipe body, the area of the guide plates is larger than a half of the area of the cross section of the exhaust pipe body, the guide plates are arranged in a staggered manner in the radial direction in the exhaust pipe body, and horizontal three-way catalytic layers are arranged among the guide plates. The three-way catalytic exhaust pipe with the guide plates aims at solving the problems that in the prior art, a filtering plate is arranged on the inner wall of a pipeline, so that all exhaust cannot flow through the filtering plate, and the filtering effect is limited.
