Tail gas filter with good black smoke filter effect

The invention relates to a tail gas filter with a good black smoke filter effect. The tail gas filter comprises a filter box (1), wherein a first filter screen (2), a first ceramic honeycomb carrier (3), a second ceramic honeycomb carrier (7) and a second filter screen (8) are sequentially arranged in the filter box (1) in the airflow direction, and each ceramic honeycomb surface is coated with anacid-resistant coating. The tail gas filter with the good black smoke filter effect is good in acid resistance; a tail gas comprising the main components of CO, HC and NOx is reacted to generate CO2,H2O, N2 and O2 under the four-stage filter of the first filter screen, the first ceramic honeycomb carrier, the second ceramic honeycomb carrier and the second filter screen; and meanwhile, micropores in a partition wall are capable of effectively filtering black smoke particles in waste gas, and the black smoke particles are combusted under the action of catalyst coatings, so that the purification effect for the tail gas is further improved.
