Abstract

resumo "sistema de tratamento de descargas que possui um scr com uma entrada central" a presente invenção refere-se a um sistema de tratamento de descarga para um veículo de trabalho, que possui um canal de descarga que transmite um fluxo de descarga de um motor para um sistema doc. o sistema doc possui um redutor introduzido e misturado no fluxo de descarga, e um canal doc conecta o doc a uma entrada central de um scr. o scr inclui pelo menos duas câmaras de descarga. quando o fluxo de descarga entra no scr na entrada central em uma câmara central onde é dividido em pelo menos dois fluxos de descarga separados que são movidos em pelo menos duas direções diferentes entre si. cada fluxo de descarga separado é movido através de uma câmara de descarga separada e substrato. um canal move pelo menos um dos fluxos de descarga separados para uma área que retém outro fluxo de descarga, e os dois fluxos de descarga separados são combinados e expelidos através de uma saída.
