An apparatus for use in the treatment of contaminated fluid is provided. The apparatus includes an outer element into which contaminated fluid flows and an inner element positioned in substantial axial alignment within the outer element and in spaced relations thereto. The apparatus also includes, between its ends, a pathway defined by an interior surface of the inner element and along which treated fluid may be directed out from the apparatus. A waste nanoadsorbent material can be provided between the outer element and the inner element, for use in removing contaminants within the fluid flowing through the apparatus. A method for the treatment of contaminated fluid is also provided.

An improved, efficient, and regenerable exhaust emission filter and filter system are provided which incorporate the use of an inorganic, non-woven fiber filter element. The filter is able to capture exhaust pollutants and particulates through the interwoven nature of the filter element and due to area enhancements applied to the filter element including microscopic enhancements. The filter has an improved life and is able to combust a greater percentage of trapped particulates due to the high temperatures the filter element can withstand. The filter element if formed from a non-woven fiber block which is machined or shaped into a filter foundation. The filter element can have a multitude of coatings and catalysts applied and can be wrapped in insulation and a casing. The improved exhaust emission filter is particularly useful for diesel engine exhausts.

The invention concerns a device for reducing the amount of soot particles discharged from the exhaust gas system of an internal combustion engine. Owing to the addition of an additive to the fuel, the ignition temperature of the soot particles during afterburning is reduced to between approximately 300 and 350.degree. C., so dropping far below the normal operating temperature of the unit. Consequently the regeneration process of the filter in the unit starts comparatively early. An essential component of the present invention is the so-called deep-bed filter which is composted of a plurality of rolled-up tubes of special ceramic thread and a heat-resistant resilient steel wire. The special production method and special construction of the ceramic stack according to the invention guarantee a satisfactory useful life of the soot filter which withstands vibrations and mechanical stresses.

An exhaust gas purification filter comprising a metal porous body obtained by packing and fixing metal fibers having a mean fiber diameter of 5 to 40 .mu.m or heat resistant ceramic fibers having a mean fiber diameter of 1 to 40 .mu.m in a dispersed state into pores of a foamed structure porous body made of a heat-resistant metal so that a packing density of the resulting metal porous body is from 5 to 20%. The filter may be in a laminated structure by laminating the foregoing foamed structure porous body filled with or without the metal or ceramic fibers and a fiber structure porous body obtained by fixing metal fibers having a mean diameter of 5 to 40 .mu.m or heat-resistant ceramic fibers having a mean diameter of 1 to 40 .mu.m in a dispersed state so that a packing density is from 5 to 25% are laminated. By using the inventive filter for collecting PM (dry soot, fine particles and SOF) contained in an exhaust gas of a Diesel engine, a pressure loss for the exhaust gas is minimized while high collection efficiency is kept.

摘要:
A device and method for maintaining a clean gas stream includes a particulate filter comprising of support tube made from a formed textile. The formed textile is constructed from a continuous filament inorganic yarn and is porous to allow gas and particulates therein to pass through the support tube. A filtering element is disposed about the support tube to trap particulates in the exhaust gas. The formed textile which defines the support tube is relatively flexible in its natural state. To act as a supporting structure, the formed textile is made less flexible by the application of an inorganic binder. The natural flexibility of the formed textile minimizes the damaging effects of mechanical and thermal shock, while the inorganic binder stiffens the formed textile and allows the support tube to support itself and the filtering element thereon.
