Abstract: In filtering particles such as soot from a flue gas a porous filter body of a particulate material bonded together in the body is employed. The material is a metal or metal-like material having a thermal conductivity in excess of 10 W/mK, and the porous filter body has a porosity of 50-90% and a maximum pore size of 10-40 .mu.m. In accordance with the method, the flue gas is conducted through the porous filter body so as to accumulate the particles in the porous filter body. The particles accumulated in the porous filter body are burned off, whereby heat is generated locally. The heat generated locally by the burning-off of the particles is conducted throughout the porous filter body so that the temperature rise generated by the burning-off heat is reduced. Consequently, the porous filter body is not exposed to fatal thermal stresses. A particular application of the porous filter body of the flue gas filter means is in vehicles comprising combustion engines generating soot, such as in diesel engines.

Abstract translation: 在从烟道气中过滤诸如烟灰的颗粒时，使用在体内结合在一起的颗粒材料的多孔过滤体。 该材料是导热率超过10W / mK的金属或类金属材料，多孔过滤体的孔隙率为50-90％，最大孔径为10-40μm。 根据该方法，烟道气通过多孔过滤器主体进行传导，以将颗粒积聚在多孔过滤体中。 积聚在多孔过滤器主体中的颗粒被烧掉，从而局部产生热量。 通过颗粒的燃烧局部产生的热量贯穿整个多孔过滤​​体进行，使得由燃烧热产生的温度降低。 因此，多孔过滤体不会受到致命的热应力的影响。 烟道气过滤装置的多孔过滤体的特定应用是包括产生烟灰的燃烧发动机的车辆，例如柴油发动机。

Abstract: A rotating particulate trap is disclosed, which may find application in diesel engines, air conditioning systems, industrial air-filters and the like. The invention includes a disk or cylinder which is formed from material suitable for filtering particulates which are present in the exhaust gases of diesel engines, gas turbines, industrial air or other particulate laden gases. The disk is mounted transversely in the exhaust duct of a diesel engine and in a fresh air duct which is disposed parallel to the exhaust duct. As the disk rotates within the exhaust duct, it filters particulates from the exhaust gases of the diesel engine. The filtered particulates are expelled from the disk by fresh air blowing in the air duct as the disk rotates within the air duct. The fresh air is blown in the air duct in a direction opposite to the flow of exhaust gases within the exhaust duct by a fan or compressor or compressed air jets. The counterflow arrangement of fresh air and combustion gases enhances the effectiveness of particulate removal as the disk rotates between the exhaust duct and the fresh air duct. Particulates expelled from the disk are blown into a filter bag which is attached to the end of the fresh air duct.

Abstract: In a filter consisting of holoow cylindrical open-pore ceramic foam cylinder elements and an end plate made of gas-impermeable material, as an insert in a filter cup for cleaning exhaust gases of diesel engines, in which the exhaust gases flow through the active filter section essentially perpendicularly to the cylinder axis, bending moments which lead to breakage of the ceramic foam cylinder elements occur during fitting of the elements due to lack of surface evenness and plane-parallelism of the end faces. A filter of the aforementioned kind, in which the end faces of the ceramic foam cylinder elements are provided with temperature-resistant and thermal shock-resistant layers of material which are plastic at room temperature, avoids the bending moments.
