▎ 摘　　要

NOVELTY - The device has an inner cylinder end cover (9) side wall that is uniformly provided with multiple holes (21). The inner cylinder end cover is fixed on the upper surface with multiple hard springs (18). Multiple hard springs are supported and connected with clapboard (19). The outer cylinder upper cover (2) is fixed with the exhaust pipe (1). The outer cylinder lower cover (7) is fixed at one end of the exhaust gas inlet pipe (8). The exhaust gas inlet pipe is connected under the outer cylinder cover that orderly passes through the inner cylinder end cover and a baffle. The exhaust gas inlet pipe is located at one end of the clapboard is provided with a baffle. The metal layer at the upper end of the silicon carbide (SiC) particle trap (3) is provided with a pressure monitoring sensor (11). USE - Graphene diesel engine exhaust purification device. ADVANTAGE - The device effectively avoids the individual uses ceramics filter and avoids the spraying time. The device is simple and convenient for use, and reduces the labor cost, technical cost and time cost. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene diesel engine exhaust purification device.
