Abstract
The invention relates to the field of automobile tail gas treatment, in particular to an automobile three-way catalyst convenient to detach. The automobile three-way catalyst convenient to detach comprises a catalyst shell, an air inlet pipe and an air outlet pipe, wherein the air inlet pipe and the air outlet pipe are connected with the two ends of the catalyst shell respectively. The automobile three-way catalyst convenient to detach is characterized by further comprising an air inlet pipe edge thickening layer located at the edge of the air inlet pipe and is separately attached to the outer edge of the catalyst shell, and when the air inlet pipe edge thickening layer is separated from the outer edge of the catalyst shell, the air inlet pipe and the catalyst shell are separated, and a cleaning agent carrier in the catalyst shell is exposed. According to the automobile three-way catalyst convenient to detach, a filtering piece is used for filtering tail gas to some extent to prevent internal particles and the like from blocking holes of the cleaning agent carrier. The structure that the air inlet pipe and the catalyst shell are separated is adopted, and the catalyst shell is opened so that the cleaning agent carrier, the filtering piece and other structures can be detached. An air outlet pipe front end flow guide piece of an arch structure is adopted, air is guided to mainly flow in the middle, and tail gas settlings are prevented from accumulating at the front end of the catalyst shell.
