Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b):

referring to fig. 1-3, the present invention provides an external automobile exhaust processor, which includes two shells 1, the outer edge of the shells 1 is integrally connected to a fixing edge 2, and mounting holes 3 are formed on the fixing edge 2 at intervals;

an exhaust port 4, wherein the bottom of the shell 1 is provided with the exhaust port 4;

the three-way catalytic inner core 5 is placed in the shell 1;

the active carbon cotton block 6 is placed in the shell 1, and the active carbon cotton block 6 is located below the ternary catalysis inner core 5.

Specifically, as shown in fig. 1, the upper portion of the shell 1 is obliquely contracted, the inner side of the shell 1 protrudes to form a ring table, the three-way catalytic inner core 5 is arranged on the ring table, the upper portion of the three-way catalytic inner core 5 is obliquely contracted with the upper portion of the shell 1, the structure is matched, the placement is fixed, and the installation is convenient.

Specifically, as shown in fig. 1, 2 and 3, the bottom of the casing 1 is curved and bent, and the exhaust port 4 is opened at the bent part of the casing 1, so that the activated carbon cotton block 6 can be conveniently placed, the activated carbon cotton block 6 is large in size and fully contacts with tail gas, and the exhaust is smooth.

Specifically, as shown in fig. 1, the bottom of the ternary catalysis inner core 5 protrudes to form a circular truncated cone, and an arc groove is formed in the bottom of the circular truncated cone, so that the activated carbon cotton block 6 can be conveniently fixed.

Specifically, the top of the activated carbon cotton block 6 is clamped in an arc groove of the circular truncated cone, and the activated carbon cotton block 6 is prevented from being located by limiting the structure.

Specifically, as shown in fig. 2, the lower part of the activated carbon cotton block 6 is in arc fit with the bottom of the shell 1, and the upper part of the activated carbon cotton block 6 is of an upward convex arc structure, so that the activated carbon cotton block 6 is prevented from blocking a tail gas channel, and the tail gas emission is not smooth.

The working principle is as follows:

when the three-way catalytic inner core is used, the three-way catalytic inner core 5 is fitted and clamped at the position of the annular table, then the activated carbon cotton block 6 (adsorbing solid particles in tail gas) is placed at the lower part of the shell 1, and the activated carbon cotton block 6 can naturally recover to the original shape after being filled, so that the top of the activated carbon cotton block 6 is fitted and clamped into the arc groove of the three-way catalytic inner core 5, the activated carbon cotton block 6 is fixed, and finally the two shells 1 are closed and fixed by bolts and nuts along the mounting holes 3 on the fixing edge 2;
