背景技术Background technique
随着汽油车辆的数量急剧增长，目前车辆尾气污染已经成为各国大气的最主要污染源之一。为了车辆达到的排放标准的环保要求，通常就是在车辆排气管中安装三元催化装置，它将汽车排放出的有害气体CO、HC和NOx 通过氧化和催化作用转变为无毒无害的二氧化碳、水和氮气。但多年来结合催化装置的生产模式，传统三元催化器的催化方式是轴向催化，轴向催化局限于容腔内径尺寸、载体的位置，气流往往集中在载体轴向的中心位置，压力损失较大，载体中心流速不均匀。With the rapid increase in the number of gasoline vehicles, vehicle exhaust pollution has become one of the most important sources of air pollution in various countries. In order to meet the environmental protection requirements of the emission standards of the vehicle, a three-way catalytic device is usually installed in the vehicle exhaust pipe, which converts the harmful gases CO, HC and NOx emitted by the vehicle into non-toxic and harmless carbon dioxide through oxidation and catalysis , water and nitrogen. However, combined with the production mode of the catalytic device for many years, the catalytic method of the traditional three-way catalytic converter is axial catalysis. The axial catalysis is limited to the inner diameter of the cavity and the position of the carrier. Larger, the flow velocity in the center of the carrier is uneven.
随着各国对车辆排放要求的提升，车辆为达到排放的更高要求，三元催化载体的设计越来越长，从加大反应面积来解决汽体排放的更高要求，但对车辆发动机性能影响大，发动机背压升高，而且长期使用后传统的三元催化器载体会被一些污染颗粒堵塞，一旦催化器载体堵塞，会造成排气不畅，当传统直通的轴向排气的载体前面的孔体堵塞后，会让后面连通的载体就不能发生反应，导致发动机会背压升高，排气管温度急剧上升。所以在持续升级的排放要求下，如何不影响车辆其他性能的前提下，通过新的催化器载体转化方式来达到尾气排放系统的要求，是目前车辆动力及排气工程师们研究的方向。With the improvement of vehicle emission requirements in various countries, in order to meet the higher requirements of vehicle emissions, the design of the three-way catalytic carrier is getting longer and longer, from increasing the reaction area to solve the higher requirements of gas emissions, but the vehicle engine performance The impact is large, the engine back pressure increases, and after long-term use, the traditional three-way catalytic converter carrier will be blocked by some pollution particles. Once the catalytic converter carrier is blocked, it will cause poor exhaust. When the carrier of the traditional straight-through axial exhaust After the front hole is blocked, the carrier connected to the back will not be able to react, resulting in an increase in the back pressure of the engine and a sharp rise in the temperature of the exhaust pipe. Therefore, under the continuously upgraded emission requirements, how to meet the requirements of the exhaust emission system through a new catalytic converter carrier conversion method without affecting other vehicle performances is the current research direction of vehicle power and exhaust engineers.

参照图1，参照图4，在本发明第一方面实施中，喇叭形载体管（31），口径较小的一端连接排气管(11)，口径较大的一端连接进气管（21），载体分流凸盖（34）与导气顶盖（33）将气体向四周分散，然后气体进入喇叭形载体管内的四周空隙。喇叭形载体管由于进气口较大，形成较大的催化反应腔，而且可以使气体快速进入喇叭形载体管（31）内进行催化反应，部分未有催化反应通过径向开口向前倾的斜口排气口（43）还可以再进行催化反应，从而保障气体都进行催化反应。Referring to Fig. 1 and Fig. 4, in the implementation of the first aspect of the present invention, the trumpet-shaped carrier pipe (31), the smaller end of the caliber is connected to the exhaust pipe (11), and the end of the larger caliber is connected to the intake pipe (21), The carrier shunting convex cover (34) and the gas guide top cover (33) disperse the gas to the surroundings, and then the gas enters the surrounding spaces in the trumpet-shaped carrier tube. The trumpet-shaped carrier tube has a larger air inlet to form a larger catalytic reaction chamber, and can quickly enter the trumpet-shaped carrier tube (31) for catalytic reaction, and some parts that do not have catalytic reaction lean forward through the radial opening The oblique exhaust port (43) can also carry out catalytic reaction, thereby guaranteeing that all gases carry out catalytic reaction.
参照图3，在本发明第一方面实施中，斜口排气孔（43）是上述相邻的两个花形弹片（41）层叠加形成径向开口向前倾的间隙，由于有多个花形弹片（41）层叠加，故形成了多个径向开口向前倾的斜口排气孔（43）；气体从四周进入斜口排气孔（43），在斜口排气孔（43）内与催化剂接触进行催化反应，气体催化反应后再汇集到叠加花形弹片组载体（32）的载体集气腔（42）再排出。传统载体轴向直通反应量是以进气管直径计算，而叠加花形弹片组载体（32）是整体叠加花形弹片组载体（32）的表面积，气体接触载体面积大大增加，大大提高催化剂反应的效率。Referring to Figure 3, in the implementation of the first aspect of the present invention, the slanted exhaust hole (43) is the above-mentioned two adjacent flower-shaped shrapnel (41) stacked to form a gap in which the radial opening leans forward, because there are multiple flower-shaped The shrapnels (41) are superimposed on each other, thus forming a plurality of oblique vent holes (43) with radial openings inclined forward; the gas enters the oblique vent holes (43) from all around, and in the oblique vent holes (43) The gas is in contact with the catalyst to carry out the catalytic reaction, and after the catalytic reaction, the gas is collected into the carrier gas collection chamber (42) of the superimposed flower-shaped shrapnel group carrier (32) and then discharged. The axial straight-through reaction volume of the traditional carrier is calculated based on the diameter of the intake pipe, while the superimposed flower-shaped shrapnel group carrier (32) is the surface area of the overall superimposed flower-shaped shrapnel group carrier (32), the gas contacting carrier area is greatly increased, and the catalyst reaction efficiency is greatly improved.
在本发明第一方面实施中，叠加花形弹片组载体（32），叠加花形弹片组载体是由多个花形弹片（41）层叠加一起焊接而成的，气体旋转径向进入再排出，在催化气体反应过程的同时也可以将噪音净化，起到降低排气管噪声的作用。In the implementation of the first aspect of the present invention, the superimposed flower-shaped shrapnel group carrier (32), the superimposed flower-shaped shrapnel group carrier is formed by stacking and welding a plurality of flower-shaped shrapnel (41), and the gas rotates radially into and then discharged. During the gas reaction process, the noise can also be purified to reduce the noise of the exhaust pipe.
