组合式排气后处理／空气滤清器和灰尘排除器单元
摘要：
本发明提供一种与燃烧系统(14)以及所述燃烧系统(14)的空气滤清器(16)一起使用的组合式排气后处理／灰尘排除器单元(10)。所述单元(10)包括长形壳体(30)，所述长形壳体(30)容纳排气后处理器件(40)并且具有从所述壳体(30)径向引导排气流(12)的径向排气出口(34)，所述单元(10)还包括灰尘排除器(60)，所述灰尘排除器(60)包括定位在所述排气出口(34)中的排除器出口(62)。排气出口(34)和排除器出口(62)具有椭圆形横截面(68,70)，其中所述排除器出口横截面(70)向内与所述排气出口(34)间隔开以限定用于排气流(12)的流量减小的区域(72)，从而使排气流(12)加速穿过排除器出口(62)。
摘要（英）：

A combined exhaust gas aftertreatment/dust ejector unit (10) is provided for use with a combustion process (14) and an air cleaner (16) of the combustion process (14). The unit (10) includes an elongate housing (30) containing an exhaust gas aftertreatment device (40) and having a radial exhaust gas outlet (34) to direct an exhaust gas flow (12) radially from the housing (30), and a dust ejector (60) including an ejector outlet (62) positioned in the exhaust gas outlet (34). The exhaust gas outlet (34) and the ejector outlet (62) have elliptical shaped cross sections (68,70), with the ejector outlet cross section (70) spaced inwardly from the exhaust gas outlet (34) to define a reduced flow area (72) for the exhaust gas flow (12) to accelerate the exhaust gas flow (12) past the ejector outlet (62).
