Abstract

The invention relates to a no-black smoke tail gas filter. The no-black smoke tail gas filter comprises a filter box (1); a filter net (2) and a ceramic honeycomb carrier (3) are arranged in the filter box (1); an inclined pressing mark (2.1) and a longitudinal pressing projection (2.2) are arranged on the filter net (2); and a spraying head (9) is arranged at the front end of the filter box (1). The no-black smoke tail gas filter firstly uses sodium carbonate water mist for eliminating acid components in tail gas, then reacts the tail gas with main components of CO, HC and NOx as CO2, H2O, N2 and O2 under two grades of filtration by the filter net and the ceramic honeycomb carrier, can effectively filter black smoke particles in waste gas through micro holes in separation walls, can burn the black smoke particles under the effect of catalyst coating layers, and further improves the tail gas purifying effect.

Description

technical field [0001] The invention relates to a black-smoke-free tail gas filter, which is used for purifying automobile tail gas. It belongs to the technical field of automobile equipment. Background technique [0002] At present, many ordinary automobile exhaust filters are directly discharged through simple filtration, and the exhaust gas of vehicles equipped with diesel engines contains black smoke particles, and the existing exhaust filters cannot effectively filter black smoke particles, which will cause Environmental pollution; the further elimination of the acidic components of the existing tail gas is a new demand for tail gas treatment and urban environmental protection. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiency, provides a kind of exhaust gas filter without black smoke, and this exhaust filter can also filter black smoke particle while filtering the harmful gas of CO, HC, NOx in automobil...
