Description
Technical Field
The utility model relates to the field of emission purification of motor vehicle internal combustion engines, in particular to a wall-flow type square-pore wood ceramic filter pressing device.
Background
With the increasing maintenance of motor vehicles, exhaust Particulate Matter (PM) emitted from internal combustion engines of motor vehicles has attracted considerable attention in recent years, and small particle size PM has been found to pose a serious threat to human health and ecological environment. Therefore, people adsorb PM discharged by adding the particle catcher, the traditional particle catcher is developed by taking the wall flow type circular honeycomb duct as a substrate, but the traditional particle catcher still has a plurality of problems at present, the filtering area of the common circular duct is relatively small, the filtering efficiency is low, most of filtering materials are synthesized artificially, the energy consumption is high, and the preparation process is complex. The wood ceramic is used as an emerging porous filtering material, can adsorb PM of tail gas, and has strong environmental friendliness and low cost. However, the experimental sample size of the wood ceramic filter body is small, and no pressing device suitable for the wood ceramic filter body exists in the market at present. Therefore, we propose a wall-flow type square duct wood ceramic filter pressing device.
