Description
Technical field
The utility model belongs to electrostatic exhaust treatment system field, more particularly, to a kind of composite automobile tail gas
Particulate filter arrangement, its strainability that can lift filter is high with filter efficiency, the advantage of strainability stabilization.
Background technology
The concentration of Atmospheric Grains and open-assembly time are the key factors of the soakage and extent of injury for determining particulate matter,
Fine particle is rich in poisonous and harmful substances, and residence time in an atmosphere is long, and fed distance is remote, and open-assembly time is long, thus right
The influence of health and atmosphere quality is bigger.Issued at the beginning of 2014 according to Chinese Ministry of Environmental Protection《Automobile pollution in 2013
Preventing and treating annual report》Understand, diesel vehicle is the one of the main reasons for causing carbon in atmosphere smoke particle too high levels, the soot of its discharge
The total amount of grain is 600,000 tons or so, accounts for the 90% of vehicle mass exhaust total quantity.By the end of 2013, the diesel vehicle recoverable amount of China was
The 25.2% of motor vehicle total amount is accounted for, its recoverable amount will be in up-trend in future.Therefore, triggered by exhaust gas from diesel vehicle discharge
Problem of environmental pollution should widely be paid close attention to.
Current particle trapper (diesel particulate filter, DPF) is the master of Fractions of Diesel Engine Exhaust Particulates treatment
Stream method.Technology development more ripe, arresting efficiency is relatively preferable.But existing DPF material for core mostly with cordierite and
