Abstract

The invention discloses a diesel exhaust particle catalytic cleaner. The diesel exhaust particle catalytic cleaner comprises a shell and a carrier. The carrier is of a helical structure formed by stacking and rolling two corrugated plates. When the carrier is unfolded and laid flat, ripples of the two corrugated plates are arranged in a crossed mode, and the included angle formed between the ripples of each corrugated plates and the width direction of the corrugated plates ranges from 30 degrees to 60 degrees. Due to the fact that the ripples of the two corrugated plates are arranged in the crossed mode, the contact area between exhaust and the carrier is increased, the contact time of exhaust and the carrier is prolonged, the catalytic reaction more fully generates, activity and efficiency of the catalytic cleaner are remarkably improved, and accumulation of particles in the catalytic cleaner is reduced.

Description

technical field [0001] The invention relates to a catalytic purifier for diesel vehicle exhaust particulate matter. Background technique [0002] According to statistics, the PM emissions in diesel vehicle exhaust exceed 90% of the total PM emissions from motor vehicles in the country. In other words, PM in diesel vehicle exhaust is the main source of PM in my country's air pollution. The PM emission in the exhaust of diesel vehicles has seriously affected the urban air quality and the health of human life, affecting the sustainable development of social economy. The treatment of PM in diesel vehicle exhaust is urgent. [0003] Diesel Particulate Filter DPF (Diesel Particulate Filter) technology is a treatment method for diesel vehicle exhaust particulate matter that is more respected in developed countries such as Europe and the United States. DPF is made of silicon carbide, cordierite and aluminum titanate, and its structure is similar to a honeycomb ceramic carrier. H...
