阅读说明：本技术 一种气体混合器 (Gas mixer ) 是由 李卫 潘洁 孙洲律 陈静 于 2018-12-29 设计创作，主要内容包括：一种气体混合器,包括混合器外壳(1)和混合器芯体(2),混合器芯体(2)包括燃气芯体(21)和EGR芯体(22),燃气芯体(21)内设置有两个交错布置的燃气喷射管(3),EGR芯体(22)内设置有四个EGR喷射管(4,5)并形成十字交叉的EGR混合芯。将气体混合器的燃气混合芯结构和EGR混合芯结构均设计为十字交叉的组合形式,从而使得燃气和EGR废气均能够从径向喷射管的多个喷射孔中喷出并充满混合器芯体(2)的截面,进而改善进入混合器芯体的燃气以及EGR废气的均匀程度,兼具较低的压力损失以及较高的工作可靠性,同时,还能够降低混合器的混合效果对下游管路导向的敏感度。(The utility model provides a gas mixer, includes blender shell (1) and blender core (2), and blender core (2) are provided with two staggered arrangement's gas injection pipe (3) including gas core (21) and EGR core (22) in gas core (21), are provided with four EGR injection pipe (4, 5) in EGR core (22) and form the EGR of cross and mix the core. The gas mixing core structure and the EGR mixing core structure of the gas mixer are designed into a cross combined form, so that gas and EGR waste gas can be sprayed out of a plurality of spray holes of the radial spray pipe and are filled with the cross section of the mixer core body (2), the uniformity of the gas entering the mixer core body and the EGR waste gas is improved, the gas mixing core structure and the EGR waste gas have lower pressure loss and higher working reliability, and meanwhile, the sensitivity of the mixing effect of the mixer to the direction of a downstream pipeline can be reduced.)
