The invention relates to a preparation method of a DPF catalytic converter, which comprises lining paper wound on a first unwinding reel, glass ceramic fiber paper wound on a second unwinding reel and a third unwinding reel The base paper; the liner paper enters the corrugated forming mold through several guide rollers; the glass ceramic fiber paper enters the corrugated forming mold at the same time as the liner paper after passing through several guide rollers and the coating device for coating the alumina filter layer, and the liner paper It is located on the top surface of the glass ceramic fiber paper; the bottom paper is glued and plugged by several guide rollers and gluing devices, and then enters the corrugated forming mold and adheres to the bottom surface of the glass ceramic fiber paper; the composite corrugated paper formed by the corrugated forming mold passes through the separating device After separating the backing paper, single-sided corrugated paper is obtained, and the single-sided corrugated paper is glued and plugged and then rolled into shape; the preparation method of a DPF catalytic converter provided by the invention has low cost, simple process, high production efficiency, and is convenient for large-scale production. Chemical industry production.
Description
technical field [0001] The invention relates to a filter device using novel glass ceramic fiber paper as a base material, in particular to a preparation method of a DPF catalytic converter. Background technique [0002] DPF = Diesel Particulate Filter diesel particulate filter, refers to the device installed in the exhaust system of diesel vehicles to reduce particulate matter (PM) in the exhaust by filtering, referred to as DPF. Diesel engines with good fuel economy and power are widely used in various industries, such as motor vehicles, generator sets, ships, etc. However, PM emissions have always been a concern. PM can be suspended in the air for a long time, pollute the environment and affect human physical and mental health. With the increasingly stringent diesel engine emission standards, diesel particulate filter (DPF) has become one of the necessary technologies for diesel vehicle exhaust emissions to meet the standards. The design of DPF must be considered in ter...
