DPF tail gas particle catcher

According to the DPF tail gas particle catcher, a shell is arranged for containing a mounting sealing plate and filter elements, the filter elements are clamped and positioned to the mounting sealing plate, a first gas pipe and a second gas pipe are connected to the two ends of the shell correspondingly, the caliber of the first gas pipe is larger than that of the single filter element, and meanwhile the distance between the first gas pipe and the mounting end is larger than the thickness of the filter elements. In this way, the space between the first air pipe and the mounting end allows the filter element to have enough space to move after the mounting sealing plate is pulled out, so that a user can conveniently mount and dismount the filter element. The caliber of the first air pipe allows a user to stretch into a hand or other equipment to directly take out the filter element from the first air cavity, so that the mounting and dismounting operations of the user are further facilitated.
