9. An engine exhaust gas treatment device according to claim 8, wherein: the shielding cover (401) is far away from the bottom of one side surface of the shell (101) and is fixedly provided with a matching block (404), the matching block (404) is matched with the fixing block (106), and a knob (405) acting on the fixing block (106) is inserted into the matching block (404).
10. An engine exhaust gas treatment device and a treatment method thereof, comprising the engine exhaust gas treatment device according to claims 1-9, characterized in that:
s1: the unscrewing knob (405) is turned, and then the retaining cover (401) is controlled to slide under the constraint of the two retaining edges (105) on the shell (101), so that the retaining cover (401) drives the top block (403) to slide away, and the force applied to the arc plate (211) is cancelled;
s2: applying a force to the arc plate (211) far away from the processing pipe (201), so that the four square blocks (213) are pulled out from the square groove holes (206) of the four first connecting plates (205), and the arc plate (211) is taken off from the processing pipe (201);
s3: four storage cylinders (301) filled with materials for treating engine exhaust are arranged in a chamber of a treatment pipe (201);
s4: the circular arc plate (211) is aligned with the position of the processing pipe (201) and is installed, then the blocking cover (401) is slid to enable the top block (403) to prop against the circular arc plate (211), the matching block (404) of the blocking cover (401) is enabled to be close to the fixed block (106) of the shell (101), and then the knob (405) is inserted and screwed.
